PROSPECTUS SUMMARY

        The following summary highlights information contained elsewhere in this prospectus. You should read carefully the entire prospectus, including "Risk Factors," our financial statements, pro forma financial information, and related notes appearing elsewhere in this prospectus, before making a decision to invest in our common stock.

        Unless indicated otherwise, the information included in this prospectus assumes (1) no exercise of the underwriters' option to purchase up to             additional shares of our common stock to cover overallotments, if any, and (2) the shares of common stock to be sold in this offering are sold at $            per share, which is the midpoint of the range set forth on the front cover of this prospectus.

        The historical operations described in this prospectus refer to the historical operations of STAG Industrial, Inc. and our predecessor business. We have generally described the business operations in this prospectus as if the historical operations of our predecessor business were conducted by us.

Overview

        STAG Industrial, Inc. is a newly formed, self-administered and self-managed full-service real estate company focused on the acquisition, ownership and management of single-tenant industrial properties throughout the United States. We will continue and grow the single-tenant industrial business conducted by our predecessor business. Benjamin S. Butcher, the Chairman of our board of directors and our Chief Executive Officer and President, together with an affiliate of New England Development, LLC ("NED"), a real estate development and management company, formed our predecessor business, which commenced active operations in 2004.

        Upon completion of our formation transactions and this offering, our portfolio will consist of 89 industrial properties in 26 states with approximately 13.5 million rentable square feet. As of June 30, 2010, our properties were 94.6% leased to 72 tenants, with no single tenant accounting for more than 5.5% of our total annualized rent and no single industry accounting for more than 14.6% of our total annualized rent.

        We target the acquisition of individual Class B, single-tenant industrial properties predominantly in secondary markets throughout the United States with purchase prices ranging from $5 million to $25 million. We believe our focus on owning and expanding a portfolio of such properties will generate returns for our shareholders that are attractive in light of the risks associated with these returns because:

Table of Contents

For a description of what we consider to be Class A and Class B properties, see "Business—Our Properties."

        Our target properties are generally leased to:

        We believe the market inefficiently prices our target properties because investors underestimate the probability of tenant retention beyond the primary lease term, or overestimate the expected cost of tenant default. Further, we believe our underwriting processes, utilizing our proprietary model, allows us to acquire properties at a discount to their intrinsic values, where intrinsic values are determined by the properties' future cash flows.

        When we refer to an "investment grade credit tenant," we mean a tenant that has a published senior unsecured credit rating of BBB-/Baa3 or above from one or both of Standard & Poor's or Moody's Investors Service. When we refer to a sub-investment grade credit tenant, we mean a tenant that is not an investment grade credit tenant.

        We were incorporated on July 21, 2010 under the laws of the State of Maryland. We intend to elect and qualify to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the "Code"), for the year ending December 31, 2010, and generally will not be subject to U.S. federal taxes on our income to the extent we currently distribute our income to our shareholders and maintain our qualification as a REIT. We are structured as an umbrella partnership REIT ("UPREIT") and will own substantially all of our assets and conduct substantially all of our business through our operating partnership. Our principal executive offices are located at 99 Chauncy Street, 10th Floor, Boston, Massachusetts 02111. Our telephone number is (617) 574-4777. Our website is www.stagreit.com. The information found on, or otherwise accessible through, our website is not incorporated into, and does not form a part of, this prospectus or any other report or document we file with or furnish to the SEC.

Our Strategies

        Our primary business objectives are to own and operate a balanced and diversified portfolio of single-tenant industrial properties that maximizes cash flows available for distribution to our shareholders, and to enhance shareholder value over time by achieving sustainable long-term growth in funds from operations ("FFO") per share through the following strategies.

        Our primary investment strategy is to acquire individual Class B, single-tenant industrial properties predominantly in secondary markets throughout the United States through third-party purchases and structured sale-leasebacks featuring high initial yields and strong ongoing cash-on-cash returns.

        We believe secondary markets tend to have less occupancy and rental rate volatility and less buyer competition compared with primary markets. As of June 30, 2010, our properties had an average annualized rent of $3.97 per rentable square foot of leased space. Our low average rent baseline reduces turnover because, from a tenant's perspective, the costs of relocating may seem expensive compared to continued payment of our prevailing rent.

        The performance of single-tenant properties tends to be binary in nature—either a tenant is paying rent or the owner is paying the entire carrying costs of the property. We believe that this binary nature frequently causes the market to inefficiently price our target assets due to the rigid application of decision rules. For example, we believe that many buyers of single-tenant properties avoid acquisitions where the tenant does not have an investment grade rating or where the remaining primary lease term is less than an arbitrary number such as 12 years.

        We further believe that our method of using and applying the results of our due diligence and our ability to understand and underwrite risk allows us to exploit this market inefficiency. Lastly, we believe that the systematic aggregation of individual properties will result in a diversified portfolio that mitigates the risk of any single property and will produce sustainable returns which are attractive in light of the associated risks. A diversified portfolio with low correlated risk—essentially a "virtual industrial park"—facilitates debt financing and mitigates individual property ownership risk.

        External Growth through Acquisitions:    Our target acquisitions will be predominantly in secondary markets across the United States, in the $5 million to $25 million range. Where appropriate potential returns present themselves, we also may acquire assets in primary markets. We will continue to develop our large existing network of relationships with real estate and financial intermediaries. These individuals and companies give us access to significant deal flow—both those broadly marketed and those exposed through only limited marketing. We believe that a significant portion of the 14 billion square feet of industrial space in the United States falls within our target investment criteria and that there will be ample supply of suitable acquisition opportunities.

        Internal Growth through Asset Management:    Our asset management team will seek to maximize cash flows by maintaining high retention rates and leasing vacant space, managing operating expenses and maintaining our properties. We seek to accomplish these objectives by improving the overall performance and positioning of our assets by utilizing our tenant relationships and leasing expertise to maintain occupancy and increase rental rates. Our asset management team collaborates with our internal credit function to actively monitor the credit profile of each of our tenants on an ongoing basis. Additionally, we work with national and local brokerage companies to market and lease available properties on advantageous terms. During the period from March 3, 2004 to June 30, 2010, the management company achieved a lease renewal rate of 81.2% based on square footage. As of June 30,

4


Table of Contents


2010, our portfolio had approximately 733,736 square feet, or 5.4% of our total rentable square feet, available for lease.

        We believe that our market knowledge, systems and processes allow us to analyze efficiently the risks in an asset's ability to produce cash flow going forward. We blend fundamental real estate analysis with corporate credit analysis in our proprietary model to make a probabilistic assessment of cash flows that will be realized in future periods. For each asset, our analysis focuses on:

        We intend to preserve a flexible capital structure and to utilize primarily debt secured by pools of properties. We are currently negotiating with several financial institutions regarding the establishment of a $         million corporate credit facility (subject to increase to $         million under certain circumstances) that we anticipate will close contemporaneously with the closing of this offering. We expect to fund property acquisitions initially through a combination of cash available from offering proceeds, this corporate credit facility and traditional mortgage financing. Where possible, we also anticipate using common units of limited partnership interest in our operating partnership ("common units") to acquire properties from existing owners seeking a tax-deferred transaction. We intend to meet our long-term liquidity needs through cash provided by operations and use of other financing methods as available from time to time including, but not limited to, secured and unsecured debt, perpetual and non-perpetual preferred stock, additional common equity issuances, letters of credit and other arrangements. In addition, we may invest in properties subject to existing mortgages or similar liens.

Market Overview

        Unless otherwise indicated, all information contained in this Market Overview section is derived from market materials prepared by CBRE-EA as of September 14, 2010, and the projections and beliefs of CBRE-EA stated herein are as of that date.

        As of June 30, 2010, the overall U.S. industrial market consisted of approximately 269,000 buildings with more than 14 billion square feet of space. In terms of net rentable area ("NRA"), warehouse/distribution facilities constitute the majority (60.1%) of this space followed by manufacturing (25.1%) and flex/office (which includes research and development) (11.8%). Unclassified buildings (industrial facilities such as sewage treatment centers and airport hangars that are not amenable to private real estate investment) represent the remaining 3.0%.

        The single-tenant industrial sector offers investors the opportunity to receive stable income from leases to a variety of firms across the spectrum of industrial sub-property types, and single-tenant industrial buildings are more likely to provide their owners with less volatile cash flows after expenses, as they generally do not require the same degree of tenant and capital improvement expenditures that are required on an ongoing basis to lease multi-tenanted space or other classes of commercial property.

Debt Financing and Liquidity

        As of June 30, 2010, on a pro forma basis, we expect to have mortgage debt outstanding with an estimated aggregate balance of approximately $166.9 million secured by the majority of the contributed properties at a weighted average annual interest rate of 5.8%. All of this debt will bear interest at a fixed rate through its initial term. Of the $166.9 million of fixed rate debt we expect to have outstanding, $73.0 million is fixed as a result of interest rate swaps. This debt will be comprised of a $73.0 million loan maturing in 2012, an $85.4 million loan maturing in 2018 and an $8.5 million loan maturing in 2027. See "Business—Description of Certain Debt" for more information about such debt.

        We are currently negotiating with several financial institutions regarding the establishment of a $         million corporate credit facility (subject to increase to $         million under certain circumstances), that we anticipate will close contemporaneously with the closing of this offering. In addition, we are currently negotiating the extension of the maturity date of our debt due in 2012. The pro forma debt yield on this instrument is        %. No assurances can be given that we will obtain any credit facility or extension or if we do what the terms will be.

        Upon completion of this offering and after the debt paydowns discussed under "Use of Proceeds," we expect to have approximately $   million in cash and $         million in credit facility capacity immediately available to us, and upon satisfaction of certain lender conditions, $       million in credit facility capacity, to fund working capital and property acquisitions and to execute our business strategy.

Our Formation Transactions and Structure

        We have deployed more than $1.3 billion through four private equity real estate funds, SCP Green, LLC ("Fund I"), STAG Investments II, LLC ("Fund II"), STAG Investments III, LLC ("Fund III") and STAG Investments IV, LLC ("Fund IV"), and one joint venture, STAG GI. We were formed to acquire the existing assets and operations of our predecessor business.

        Our senior management team consists of Mr. Butcher, the Chairman of our board of directors and our Chief Executive Officer and President, Gregory W. Sullivan, our Chief Financial Officer, Executive Vice President and Treasurer, Stephen C. Mecke, our Chief Operating Officer and Executive Vice President, Kathryn Arnone, our Executive Vice President, General Counsel and Secretary, and David G. King, our Executive Vice President and Director of Real Estate Operations. They have each led or helped manage private and public real estate companies and funds, including STAG, AMB Property Corp., Trizec Hahn Corporation, Meditrust Corporation and LaQuinta Corporation.

        Prior to or concurrent with the completion of this offering, we will engage in the following formation transactions, which are designed to consolidate the ownership of our property portfolio under our operating partnership and its subsidiaries, consolidate our acquisition and asset management

businesses into a subsidiary of our operating partnership and enable us to qualify as a REIT for U.S. federal income tax purposes commencing with the taxable year ending December 31, 2010:

        We will not enter into any tax protection agreements in connection with our formation transactions.

        Following completion of our formation transactions, Fund II will continue to operate as a private, fully-invested fund and will retain ownership of its 86 properties, with approximately 13.1 million rentable square feet. We will enter into a services agreement with Fund II on terms we believe to be customary, pursuant to which we will manage its properties in return for an annual asset management fee based on the equity investment in such assets, which will initially equal 0.94% of the equity investment and may increase up to 1.25% of the equity investment to the extent assets are sold and the total remaining equity investment is reduced.

        Following completion of our formation transactions, Fund III will retain ownership of three properties with approximately 890,891 rentable square feet that are vacant and that are acquisition opportunities for us (the "Option Properties"). Following completion of our formation transactions, we will enter into a services agreement with Fund III pursuant to which we will manage the Option Properties for an annual fee of $30,000 per property and provide the limited administrative services

Fund III will require until its liquidation for an annual fee of $20,000. Upon approval of our independent directors, we will have the right to acquire any of the Option Properties individually.

        In addition, we will enter into a services agreement with Fund IV pursuant to which we will provide the limited administrative services Fund IV will require until its liquidation for an annual fee of $20,000. STAG GI will not require administrative services from us or our affiliates following completion of our formation transactions.

        Following completion of our formation transactions, Fund II, Fund III, Fund IV and STAG GI will make no additional property acquisitions, and our senior management team will devote substantially all of its business time to our business.

        Upon completion of our formation transactions and this offering, our directors and executive officers and their affiliates will receive material financial and other benefits, as shown below. For a more detailed discussion of these benefits see "Management," "Certain Relationships and Related Transactions" and "Structure and Formation of Our Company—Benefits of Our Formation Transactions and this Offering to Certain Parties."

        Formation Transactions.    Fund III, Fund IV, STAG GI and the members of the management company will receive                common units as a result of their contribution to us of the entities owning our properties and the management company, as described above under "—Our Formation Transactions and Structure—Formation Transactions." In addition, upon completion of our formation transactions, we will repay or assume indebtedness secured by our properties and unsecured indebtedness, as described under "—Our Formation Transactions and Structure—Formation Transactions" and "Use of Proceeds." The table below sets forth a list of what individual directors and executive officers of our company will receive as a result of the contributions.

The amounts shown in the table reflect common units received by the individual directly or received by any entity, but if by an entity only to the extent of the individual's interest in the assets of the entity. Accordingly, the amounts shown in the table above do not reflect common units received by entities that may be controlled by the individual (except to the extent of the individual's interest in the assets of the entity).

(2)
Consists of our executive officers' investments in Fund III, Fund IV and STAG GI and their residual interests in Fund III, Fund IV and STAG GI. Solely for purposes of this table, we calculated our executive officers' residual interests assuming Fund III, Fund IV and STAG GI are liquidated upon the closing of this offering at $            per share, which is the midpoint of the price range set forth on the front cover of this prospectus and made certain other assumptions. See "—Benefits to Related Parties—Formation Transactions" below.

(3)
Based upon an assumed initial public offering price of $            per share, which is the midpoint of the price range set forth on the front cover of this prospectus.

        Upon completion of our formation transactions and this offering, Fund III will receive                common units, Fund IV will receive                common units, STAG GI will receive                common units and the management company will receive                common units. The number of common units that Fund III, Fund IV, STAG GI and the management company will receive in our formation transactions (an aggregate of                common units) is fixed and will not change based on the ultimate initial public offering price in this offering.

        After the expiration of the lock-up period, Fund III, Fund IV and STAG GI may distribute its common units to its members in accordance with the fund's operating agreement. In addition to their invested equity, certain members of Fund III, Fund IV and STAG GI, including certain of our officers, employees and directors, have residual interests, or contingent profit interests, in Fund III, Fund IV and STAG GI. As a result, they may receive distributions related to these residual interests if there are sufficient proceeds after return of capital and preferred returns to themselves and the other equity investors in Fund III, Fund IV and STAG GI. In all cases where there is a residual distribution, the

14


Table of Contents


higher the share price of our common stock at the time a fund is liquidated, the greater the portion of the common units the fund will distribute to the holders of the residual interests.

        The number of common units being issued to each fund in our formation transactions is fixed so that residual interests will not, in any manner, require us to issue additional common units or shares of common stock or otherwise dilute investors in this offering. In addition, because the value of the residual interests depends on the value of our common stock, not on the value of certain properties or portfolios individually, such residual interests align the interests of the holders of residual interests with the interests of our company and shareholders. See "Structure and Formation of Our Company—Benefits of Our Formation Transactions and the Offering to Certain Parties."

        Voting Agreement.    An affiliate of GI Partners will receive rights to designate two nominees for election to our board of directors, and Fund III, Fund IV, STAG GI and the contributors of the management company will enter into a voting agreement pursuant to which they will vote any shares of common stock that they own in favor of the election of the two nominees at each annual meeting of shareholders.

        Services Agreements and Option Agreement.    We will enter into services agreements with each of Fund II, Fund III and Fund IV and an option to purchase agreement with Fund III with respect to the Option Properties. See "—Our Formation Transactions and Structure—Services Agreements and Option Properties."

        Registration Rights Agreement.    We have agreed to file a shelf registration statement with the Securities and Exchange Commission ("SEC") covering the resale of the shares of common stock issued or issuable in exchange for common units issued in our formation transactions, the shares of common stock underlying LTIP units and any shares of restricted common stock issued to our directors and officers. We have also agreed to provide rights to these holders of common units to demand additional registration statement filings.

        Employment Agreements.    Messrs. Butcher, Sullivan, Mecke and King and Ms. Arnone will enter into employment agreements with us providing for salary, discretionary bonus and other benefits.

        Equity Incentive Plan Grants.    We will issue                LTIP units to our executive officers and                shares of restricted common stock to our executive officers and non-management directors pursuant to our 2010 Equity Incentive Plan, representing in the aggregate        % of the total number of shares of our common stock outstanding on a fully-diluted basis.

        Director Compensation.    We will pay annual fees to each of our non-management directors for services as a director. Any non-management director who joins our board of directors in the future will receive an initial grant of restricted shares of common stock upon attendance at his or her first board meeting. See "Management—Board Compensation."

        Indemnification Agreements.    Our bylaws provide that we will indemnify our directors, executive officers and employees to the fullest extent permitted by Maryland law. We also intend to enter into indemnification agreements with our directors and executive officers. See "Management—Limitation on Liabilities and Indemnification of Directors and Officers."

Conflicts of Interest

        The executive officers for each of the managers of Fund II, Fund III, Fund IV and STAG GI consist of a number of persons who serve as executive officers in similar positions in our company, specifically: Messrs. Butcher, Sullivan, Mecke and King and Ms. Arnone. Also, Mr. Butcher, who is a member of our board of directors, also serves on the board of managers and/or management committees of the managers of Fund II, Fund III and Fund IV, and is a member of the board of

15


Table of Contents


directors of STAG GI. Our executive officers and certain of our directors may have conflicting duties because they have a duty to both us and to Fund II (which will retain ownership of its properties and continue as a private, fully-invested fund until liquidated), Fund III (which will retain ownership of the Option Properties), Fund IV and STAG GI. Upon completion of our formation transactions, all of these entities will be fully invested and, as a result, will not be making any additional investments in income properties. It is possible that the executive officers' and board members' fiduciary duty to Fund II, Fund III, Fund IV and STAG GI, including, without limitation, their interests in Fund II and the Option Properties, will conflict with what will be in the best interests of our company.

        We did not conduct arm's-length negotiations with respect to the terms and structuring of our formation transactions, resulting in the principals of the management company having the ability to influence the type and level of benefits that they and our other affiliates will receive. We have not obtained third-party appraisals of the properties to be contributed to us in our formation transactions or fairness opinions in connection with our formation transactions.

        Additional conflicts of interest could arise in the future as a result of the relationships between us and our affiliates, on the one hand, and our operating partnership or any partner thereof on the other. Our directors and officers have duties to our company under applicable Maryland law in connection with their management of our company. At the same time, we, as the indirect general partner of our operating partnership, have duties to our operating partnership and to its limited partners in connection with the management of our operating partnership under Delaware law as modified by our operating partnership agreement. Our duties, as the indirect general partner of our operating partnership, may come into conflict with the duties of our directors and officers to our company.

        We plan to adopt policies to reduce potential conflicts of interest. Generally, our policies will provide that any transaction involving us in which any of our directors, officers or employees has an interest must be approved by a vote of a majority of our disinterested directors. However, we cannot assure you that these policies will be successful in eliminating the influence of these conflicts. See "Policies with Respect to Certain Activities—Conflicts of Interest Policies."

Tax Status

        We will elect to be taxed as a REIT under the Code commencing with our taxable year ending December 31, 2010. As a REIT, we generally will not be subject to U.S. federal income tax on income that we distribute currently to our shareholders. Under the Code, REITs are subject to numerous organizational and operational requirements, including the distribution requirement described below. If we fail to qualify for taxation as a REIT in any year, our income will be taxed at regular corporate rates, we will not be allowed a deduction for dividends to our shareholders in computing our taxable income and we may be precluded from qualifying for treatment as a REIT for the four-year period following the year of our failure to qualify. Even if we qualify as a REIT for U.S. federal income tax purposes, we may still be subject to state and local taxes on our income and property and to U.S. federal income and excise taxes on our undistributed income.

Distribution Policy

        We are a newly formed company that has not commenced operations, and as a result, we have not paid any distributions as of the date of this prospectus. U.S. federal income tax law generally requires that a REIT distribute annually at least 90% of its REIT taxable income, determined without regard to the deduction for dividends paid and excluding any net capital gains. To satisfy the requirements to qualify as a REIT and generally not be subject to U.S. federal income tax, we intend to make quarterly distributions of all or substantially all of our net income to holders of our common shares out of assets legally available therefor. We intend to pay a pro rata initial distribution with respect to the period commencing on the completion of this offering and ending at the last day of the then-current fiscal

16


Table of Contents


quarter, based on a distribution of $            per share for a full quarter. On an annualized basis, this would be $            per share, or an annual distribution rate of approximately             %, based on the midpoint of the range set forth on the cover page of this prospectus. We estimate this initial annual distribution rate will represent approximately            % of estimated cash available for distribution to our common shareholders for the 12 months ending June 30, 2011. We intend to maintain our initial distribution rate for the 12-month period following completion of this offering unless our actual results of operations, economic conditions or other factors differ materially from the assumption used is our estimate. Any future distributions we make will be at the discretion of our board of directors and will depend upon our earnings and financial condition, maintenance of REIT qualification, the applicable provisions of the Maryland General Corporation Law ("MGCL") and such other factors as our board may determine in its sole discretion. We anticipate that our estimated cash available for distribution will exceed the annual distribution requirements applicable to REITs. However, under some circumstances, we may be required to pay distributions in excess of cash available for distribution in order to meet these distribution requirements and may need to use the proceeds from future equity and debt offerings, sell assets or borrow funds to make some distributions. We have no intention to use the net proceeds of this offering to make distributions nor do we intend to make distributions using shares of common stock. We cannot assure you that our distribution policy will not change in the future.

Restrictions on Ownership and Transfer of Stock

        Due to limitations on the concentration of ownership of a REIT imposed by the Code, not more than 50% of the value of the outstanding shares of beneficial ownership of a REIT may be owned, directly or indirectly, by five or fewer individuals (as defined by the Code to include certain entities) during the last half of a taxable year (other than the first year for which an election to be a REIT has been made). As a result, our charter provides that, subject to certain exceptions, no person may beneficially own, or be deemed to own by virtue of the attribution provisions of the Code, either more than 9.8% in value or in number of shares, whichever is more restrictive, of our outstanding shares of capital stock, or more than 9.8% in value or in number of shares, whichever is more restrictive, of our outstanding common stock. Our board of directors may, in its discretion, exempt a person from the 9.8% ownership limits under certain circumstances. In connection with our formation transactions, our board of directors has granted a waiver to STAG GI to own up to        % of our outstanding common stock on a fully diluted basis. Our charter also prohibits any person from, among other matters: beneficially or constructively owning or transferring shares of our capital stock if such ownership or transfer would result in our being "closely held" within the meaning of Section 856(h) of the Code; owning or transferring our capital stock if such ownership or transfer would result in us becoming a "pension-held REIT" under Section 856(h)(3)(D) of the Code; transferring shares of our capital stock if such transfer would result in our capital stock being owned by fewer than 100 persons; or beneficially or constructively owning or transferring shares of our capital stock if such ownership or transfer would cause us to own, directly or indirectly, 10% or more of the ownership interests in a tenant of our company (or a tenant of any entity owned or controlled by us) or would cause any independent contractor to not be treated as such under Section 856(d)(3) of the Code, or beneficially or constructively owning shares of our capital stock to the extent such beneficial or constructive ownership would otherwise cause us to fail to qualify as a REIT. See "Description of Stock—Restrictions on Ownership and Transfer of Stock."

Lock-Up Arrangements

        We and our executive officers and directors and the owners of the management company, Fund III, Fund IV and STAG GI have agreed not to sell or transfer any common units or shares of common stock, as applicable, for a period of 180 days in the case of our company and 12 months in the case of our executive officers, directors and contributors after the date of this prospectus. Specifically, all of these parties have agreed, subject to exceptions, not to directly or indirectly offer, pledge, sell or contract to sell any common units or shares of common stock, sell any option or contract to purchase

any common units or shares of common stock, purchase any option or contract to sell any common units or shares of common stock, grant any option, right or warrant for the sale of any common units or shares of common stock, lend or otherwise dispose of or transfer any common units or shares of common stock, request or demand that we file a registration statement related to the common units or shares of common stock, or enter into any swap or other agreement that transfers, in whole or in part, the economic consequence of ownership of any common units or shares of common stock whether any such swap or transaction is to be settled by delivery of shares or other securities, in cash or otherwise.

Common stock and common units to be outstanding after completion of our formation transactions and this offering                           shares/units(1)(2)(3)
Use of proceeds   We estimate that the net proceeds we will receive from the sale of shares of our common stock in this offering will be approximately $         million (or approximately $         million if the underwriters exercise their overallotment option in full), in each case assuming a public offering price of $        per share, which is the mid-point of the range set forth on the cover of this prospectus, and after deducting underwriting discounts and commissions of approximately $         million (or approximately $         million if the underwriters exercise their overallotment option in full) and estimated organizational and offering expenses of approximately $         million payable by us. We will contribute the net proceeds we receive from this offering to our operating partnership in exchange for common units in our operating partnership.

•       approximately $219.1 million to repay mortgage debt secured by certain of the properties we will acquire in our formation transactions;

   

•       approximately $       million for general corporate purposes including acquisitions of real estate assets;

   

•       approximately $5.4 million to repay subordinate mortgage debt secured by the Option Properties (the common units to be issued to Fund III in our formation transactions will be reduced accordingly);

   

•       approximately $4.4 million to repay the loan dated January 31, 2009 from an affiliate of NED to the Fund III subsidiaries that will be contributed to us in our formation transactions;

   

•       approximately $2.8 million to repay the loan originally drawn on May 15, 2007 from Fund III to the management company;

   

•       approximately $3.3 million to terminate a portion of interest rate swaps due to the retirement of mortgage debt;

   

•       approximately $1.0 million to repay the line of credit dated May 15, 2007 from an affiliate of NED to the management company; and

   

•       approximately $0.5 million to pay transfer taxes associated with the contribution of our properties to us.

    If the underwriters exercise their overallotment option in full, we expect to use the additional $       million of net proceeds for general corporate purposes, including acquisitions of real estate assets. See "Use of Proceeds."

Table of Contents


Summary Financial Information

        The following table sets forth summary financial and operating data on (1) a pro forma basis for our company and (2) an historical basis for STAG Predecessor Group. On a pro forma basis, we will own 89 industrial properties, consisting of 57 properties owned by STAG Predecessor Group and 32 properties that constitute STAG Contribution Group. STAG Predecessor Group, which includes the entity that is considered our accounting acquirer, is part of our predecessor business and consists of the subsidiaries of Fund III that will be contributed to us by Fund III in our formation transactions. STAG Contribution Group consists of the properties owned by Fund IV and STAG GI that will be contributed to us in the formation transactions.

        In the summary financial and operating data, we have not presented historical information for STAG Industrial, Inc. because we have not had any corporate activity since our formation other than the issuance of shares of common stock in connection with the initial capitalization of our company and activity in connection with our formation transactions and this offering, and because we believe that a discussion of the results of STAG Industrial, Inc. would not be meaningful.

        We have not presented historical financial information for the management company as its results are not considered significant, and because we believe that a discussion of these results (which primarily consist of acquisition and asset management fees from Fund II, Fund III and Fund IV and general and administrative costs), would not be meaningful.

        You should read the following summary financial and operating data in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operation," our unaudited pro forma consolidated financial statements and related notes, the historical combined financial statements and related notes of STAG Predecessor Group, the historical combined statements of revenue and certain expenses and related notes of STAG Contribution Group, and the historical (combined) statements of revenue and certain expenses and related notes of the various properties listed in the Index to the Financial Statements.

        The unaudited pro forma condensed consolidated balance sheet data is presented as if this offering and our formation transactions had occurred on June 30, 2010, and the unaudited pro forma statements of operations and other data for the six months ended June 30, 2010 and the year ended December 31, 2009, is presented as if this offering and our formation transactions had occurred on January 1, 2009. The pro forma financial information is not necessarily indicative of what our actual financial condition would have been as of June 30, 2010 or what our actual results of operations would have been assuming this offering and our formation transactions had been completed as of January 1, 2009, nor does it purport to represent our future financial position or results of operations.

        The unaudited summary historical combined balance sheet information as of June 30, 2010 and statement of operations data for the six months ended June 30, 2010 and 2009 have been derived from the unaudited combined financial statements of the STAG Predecessor Group included elsewhere in this prospectus. The summary historical combined balance sheet information as of December 31, 2009 and 2008, and the historical combined statement of operations data for the years ended December 31, 2009, 2008, and 2007, have been derived from the combined financial statements of the STAG Predecessor Group audited by PricewaterhouseCoopers LLP, independent registered public accountants, whose report thereon is included elsewhere in this prospectus. The summary historical combined balance sheet information as of December 31, 2007 and 2006 and the historical combined statement of operations for the period ended December 31, 2006 have been derived from the unaudited combined financial statements of the STAG Predecessor Group, which are not included in this prospectus.

        The audited historical financial statements of STAG Predecessor Group in this prospectus, and therefore the historical financial and operating data in the table below, exclude the operating results and financial condition of the Option Properties, the entities that own the Option Properties and the management company.

RISK FACTORS

        An investment in our common stock involves risks. In addition to other information in this prospectus, you should carefully consider the following risks before investing in our common stock offered by this prospectus. The occurrence of any of the following risks could materially and adversely affect our business, prospects, financial condition, results of operations and our ability to make cash distributions to our shareholders, which could cause you to lose all or a significant portion of your investment in our common stock. Some statements in this prospectus, including statements in the following risk factors, constitute forward-looking statements. See "Cautionary Note Regarding Forward-Looking Statements."

Risks Related to Our Business and Operations

        All of our 89 properties are industrial properties, including 42 warehouse/distribution facilities, 26 manufacturing facilities and 21 flex/office facilities. This concentration may expose us to the risk of economic downturns in the industrial real estate sector to a greater extent than if our properties were more diversified across other sectors of the real estate industry.

        Our operating results may be affected by market and economic challenges, including the current global economic credit environment, which may result from a continued or exacerbated general economic slow down experienced by the nation as a whole or by the local economies where our properties may be located, or by the real estate industry, including the following:

        Also, to the extent we purchase real estate in an unstable market, we are subject to the risk that if the real estate market ceases to attract the same level of capital investment in the future that it attracts at the time of our purchases, or the number of companies seeking to acquire properties decreases, the value of our investments may not appreciate or may decrease significantly below the amount we pay for these investments. The length and severity of any economic slow down or downturn cannot be predicted. Our operations could be negatively affected to the extent that an economic slow down or downturn is prolonged or becomes more severe.

        Domestic and international financial markets recently experienced significant dislocations brought about in large part by failures in the U.S. banking system. These dislocations have impacted the availability of credit. If this dislocation in the credit markets causes the inability to borrow at attractive rates, our ability to borrow monies to finance the purchase of, or other activities related to, real estate assets will be negatively impacted. If we are unable to borrow monies on terms and conditions that we find acceptable, we likely will have to reduce the number of properties we can purchase, and the return on the properties we do purchase may be lower. Also, if the values of our properties decline we may

RISK FACTORS


we may be unable to refinance all of our debt as it matures. All of these events would have a material adverse effect on our results of operations, financial condition and ability to pay distributions.

        In addition to general, regional, national and international economic conditions, our operating performance is impacted by the economic conditions of the specific markets in which we have concentrations of properties. We have holdings in the following states (which, as of June 30, 2010, accounted for the percentage of our total annualized rent indicated): North Carolina (14.9%); Ohio (13.2%); Wisconsin (7.1%); and Michigan (6.1%). Our operating performance could be adversely affected if conditions become less favorable in any of the states or regions in which we have a concentration of properties.

        We are subject to certain industry concentrations with respect to our properties, including the following (which, as of June 30, 2010, accounted for the percentage of our total annualized rent indicated): Containers & Packaging (14.6%); Business Services (10.8%); Personal Products (8.9%); and Technology (8.1%). Such industries are subject to specific risks that could result in downturns within the industries. For example, several of our technology tenants operate in the telecommunications sector. Telecommunications companies face risks regarding their ability to adapt to new technological developments and changes in regulations by the Federal Communications Commission and other federal, state and local agencies. Any downturn in one or more of these industries, or in any other industry in which we may have a significant concentration now or in the future, could adversely affect our tenants who are involved in such industries. If any of these tenants is unable to withstand such downturn or is otherwise unable to compete effectively in its business, it may be forced to declare bankruptcy, fail to meet its rental obligations, seek rental concessions or be unable to enter into new leases, which could materially and adversely affect us.

        Any of our tenants may experience a downturn in its business at any time that may significantly weaken its financial condition or cause its failure. As a result, such tenant may decline to extend or renew its lease upon expiration, fail to make rental payments when due or declare bankruptcy. The default, financial distress or bankruptcy of a single tenant could cause interruptions in the receipt of rental revenue and/or result in a vacancy, which is likely to result in the complete reduction in the operating cash flows generated by the property leased to that tenant and may decrease the value of that property. In addition, a majority of our leases generally require the tenant to pay all or substantially all of the operating expenses normally associated with the ownership of the property, such as utilities, real estate taxes, insurance and routine maintenance. Following a vacancy at a single-tenant property, we will be responsible for all of the operating costs at such property until it can be re-let, if at all.

RISK FACTORS


        Many of our tenants rely on external sources of financing to operate their businesses. The U.S. financial and credit markets continue to experience significant liquidity disruptions, resulting in the unavailability of financing for many businesses. If our tenants are unable to obtain financing necessary to continue to operate their businesses, they may be unable to meet their rent obligations to us or enter into new leases with us or be forced to declare bankruptcy and reject our leases, which could materially and adversely affect us.

        We were organized in July 2010 and will commence operations upon completion of our formation transactions and this offering. We are subject to all the risks and uncertainties associated with any new business, including the risk that we will not achieve our investment objectives and that the value of your investment could decline substantially.

        We have no experience operating as a publicly traded REIT. We cannot assure you that our past experience will be sufficient to successfully operate our company as a REIT or a publicly traded company, including the requirements to timely meet disclosure requirements and comply with the Sarbanes-Oxley Act of 2002. Failure to maintain REIT status would have an adverse effect on our financial condition, results of operations, cash flow, per share trading price of our common stock and ability to satisfy our debt service obligations and to pay dividends to you.

        Our success depends to a significant degree upon the continued contributions of certain key personnel including, but not limited to, Messrs. Butcher, Sullivan, Mecke and King and Ms. Arnone, whose continued service is not guaranteed, and each of whom would be difficult to replace. While we have entered into employment contracts with Messrs. Butcher, Sullivan, Mecke and King and Ms. Arnone, they may nevertheless cease to provide services to us at any time. If any of our key personnel were to cease employment with us, our operating results could suffer. Our ability to retain our management group or to attract suitable replacements should any members of the management group leave is dependent on the competitive nature of the employment market. The loss of services from key members of the management group or a limitation in their availability could adversely impact our financial condition and cash flows. Further, such a loss could be negatively perceived in the capital markets. We have not obtained and do not expect to obtain key man life insurance on any of our key personnel except for Mr. Butcher, the founder of STAG. The policy has limits in the amount of $5.0 million and covers us in the event of Mr. Butcher's death.

        We also believe that, as we expand, our future success depends, in large part, upon our ability to hire and retain highly skilled managerial, investment, financing, operational and marketing personnel. Competition for such personnel is intense, and we cannot assure you that we will be successful in attracting and retaining such skilled personnel.

RISK FACTORS


        We acquire and intend to continue to acquire primarily generic distribution warehouses, manufacturing properties and flex/office facilities. The acquisition of properties entails various risks, including the risks that our investments may not perform as we expect. Further, we face competition for attractive investment opportunities from other well-capitalized real estate investors, including both publicly-traded REITs and private institutional investment funds, and these competitors may have greater financial resources than us and a greater ability to borrow funds to acquire properties. This competition will increase as investments in real estate become increasingly attractive relative to other forms of investment. As a result of competition, we may be unable to acquire additional properties as we desire or the purchase price may be significantly elevated. In addition, we expect to finance future acquisitions through a combination of secured and unsecured borrowings, proceeds from equity or debt offerings by us or our operating partnership or its subsidiaries and proceeds from property contributions and divestitures which may not be available and which could adversely affect our cash flows. Any of the above risks could adversely affect our financial condition, results of operations, cash flows and ability to pay distributions on, and the market price of, our common stock.

        A key component of our growth strategy is to continue to acquire additional industrial real estate assets. Since 2004, approximately 32.0% of the acquisitions we sourced, based on total purchase price, were acquired before they were widely marketed by real estate brokers, or "limited marketing" transactions. Properties that are acquired by "limited marketing" transactions are typically more attractive to us as a purchaser because of the absence of a formal sales process, which could lead to higher prices. If we cannot obtain "limited marketing" deal flow in the future, our ability to locate and acquire additional properties at attractive prices could be somewhat adversely affected.

        We have not obtained updated third-party appraisals of the properties and other assets to be contributed to us in our formation transactions or fairness opinions in connection with our formation transactions. The initial public offering price of our common stock was determined in consultation with the underwriters based on the history and prospects for the industry in which we compete, our financial information, the ability of our management and our business potential and earning prospects, the prevailing securities markets at the time of this offering, and the recent market prices of, and the demand for, publicly traded shares of generally comparable companies. The initial public offering price does not necessarily bear any relationship to the book value or the fair market value of such assets. As a result, the consideration for these assets in our formation transactions may exceed their book value and fair market value.

        All distributions will be made at the discretion of our board of directors and will depend on our earnings, our financial condition, maintenance of our REIT qualification and other factors as our board of directors may deem relevant from time to time. We may not be able to make distributions in the

25


Table of Contents

RISK FACTORS


future. In addition, some of our distributions may include a return of capital. To the extent that we make distributions in excess of our current and accumulated earnings and profits, such distributions would generally be considered a return of capital for U.S. federal income tax purposes to the extent of the holder's adjusted tax basis in its shares. A return of capital is not taxable, but it has the effect of reducing the holder's adjusted tax basis in its investment. To the extent that distributions exceed the adjusted tax basis of a holder's shares, they will be treated as gain from the sale or exchange of such stock. See "U.S. Federal Income Tax Considerations—Taxation of shareholders." If we borrow to fund distributions, our future interest costs would increase, thereby reducing our earnings and cash available for distribution from what they otherwise would have been.

        Prior to our formation transactions and this offering, Fund III, Fund IV and STAG GI owned or controlled our 89 initial properties comprising an aggregate 13.5 million rentable square feet. All of these properties have been under management for less than four years. The properties may have characteristics or deficiencies unknown to us that could affect their valuation or revenue potential and such properties may not ultimately perform up to our expectations. We cannot assure you that the operating performance of the properties will not decline under our management.

Risks Related to Our Organization and Structure

        Certain of our directors and executive officers have ownership interests in the other entities or properties to be contributed to us in our formation transactions, including Fund III, Fund IV, STAG GI and the management company. Following the completion of our formation transactions and this offering, under the contribution agreements with certain of our directors and executive officers and their affiliates, we will be entitled to indemnification in the event of breaches of the representations and warranties made by them with respect to the entities and properties to be acquired by us. Such indemnification is limited and we are not entitled to any other indemnification in connection with our formation transactions. See "—We are assuming liabilities in connection with our formation transactions, including unknown liabilities" above. In addition, we expect that our executive officers will enter into employment agreements with us pursuant to which they will agree, among other things, not to engage in certain business activities in competition with us and pursuant to which they will devote substantially all of their business time to our business. See "Management—Employment Agreements." We may choose not to enforce, or to enforce less vigorously, our rights under these agreements due to our ongoing relationship with our directors and executive officers.

        We did not conduct arm's-length negotiations with respect to all of the terms of our formation transactions. In the course of structuring our formation transactions, our directors and executive officers had the ability to influence the type and level of benefits that they and our other officers will receive from us. In addition, certain of our directors and executive officers had substantial pre-existing ownership interests in Fund III, Fund IV, STAG GI and the management company, and will receive substantial economic benefits as a result of our formation transactions. The formation transaction

RISK FACTORS


documents provide that the individual allocations of the total formation transaction value to each prior investor are determined by the provisions of the applicable partnership agreement or organizational document of the relevant fund. Also, our directors and executive officers have assumed management and/or director positions with us, for which they will obtain certain other benefits such as employment agreements, restricted stock or LTIP unit grants and other compensation.

        Certain of our executive officers and directors also serve on the board of managers and/or management committees of the managers of Fund II, Fund III and Fund IV, and are members of the board of directors of STAG GI. Our officers and directors may have conflicting duties because they have a duty to both us and to Fund II (which will retain ownership of its properties and continue as a private, fully-invested fund until liquidated), Fund III (which will retain ownership of the Option Properties), Fund IV and STAG GI. Upon completion of our formation transactions, all of these entities will be fully invested and, as a result, will not be making any additional investments in income properties. However, some Fund II properties may be competitive with our current or future properties. It is possible that the executive officers' and board members' fiduciary duty to Fund II, Fund III, Fund IV and STAG GI, including, without limitation, their interests in Fund II and the Option Properties, will conflict with what will be in the best interests of our company.

        After the consummation of this offering, we, as the sole member of the general partner of our operating partnership, will have fiduciary duties to the other limited partners in the operating partnership, the discharge of which may conflict with the interests of our shareholders. The limited partners of our operating partnership have agreed that, in the event of a conflict in the fiduciary duties owed by us to our shareholders and, in our capacity as indirect general partner of our operating partnership, to such limited partners, we are under no obligation to give priority to the interests of such limited partners. In addition, those persons holding common units will have the right to vote on certain amendments to the operating partnership agreement (which require approval by a majority in interest of the limited partners, including us) and individually to approve certain amendments that would adversely affect their rights. These voting rights may be exercised in a manner that conflicts with the interests of our shareholders. For example, we are unable to modify the rights of limited partners to receive distributions as set forth in the operating partnership agreement in a manner that adversely affects their rights without their consent, even though such modification might be in the best interest of our shareholders.

        In addition, conflicts may arise when the interests of our shareholders and the limited partners of the operating partnership diverge, particularly in circumstances in which there may be an adverse tax consequence to the limited partners. Tax consequences to holders of common units upon a sale or refinancing of our properties may cause the interests of our senior management to differ from your own. As a result of unrealized built-in gain attributable to contributed property at the time of contribution, some holders of common units, including our principals, may suffer different and more adverse tax consequences than holders of our common stock upon the sale or refinancing of the properties owned by our operating partnership, including disproportionately greater allocations of items of taxable income and gain upon a realization event. As those holders will not receive a correspondingly greater distribution of cash proceeds, they may have different objectives regarding the

27

RISK FACTORS



appropriate pricing, timing and other material terms of any sale or refinancing of certain properties, or whether to sell or refinance such properties at all.

        We may experience conflicts of interest with several members of our senior management team who have or may become limited partners in our operating partnership through the receipt of LTIP units granted under our 2010 Equity Incentive Plan. See "Management—Equity Incentive Plan."

        In order to maintain our qualification as a REIT, we are generally required under the Code to distribute annually at least 90% of our net taxable income, determined without regard to the dividends paid deduction and excluding any net capital gain. In addition, we will be subject to income tax at regular corporate rates to the extent that we distribute less than 100% of our net taxable income, including any net capital gains. Because of these distribution requirements, we may not be able to fund future capital needs, including any necessary acquisition financing, from operating cash flow. Consequently, we may rely on third-party sources to fund our capital needs. We may not be able to obtain financing on favorable terms or at all. Any additional debt we incur will increase our leverage. Our access to third-party sources of capital depends, in part, on:

        If we cannot obtain capital from third-party sources, we may not be able to acquire properties when strategic opportunities exist, meet the capital and operating needs of our existing properties or satisfy our debt service obligations. Further, in order to meet the REIT distribution requirements and maintain our REIT status and to avoid the payment of income and excise taxes, we may need to borrow funds on a short-term basis even if the then-prevailing market conditions are not favorable for these borrowings. These short-term borrowing needs could result from differences in timing between the actual receipt of cash and inclusion of income for U.S. federal income tax purposes or the effect of non-deductible capital expenditures, the creation of reserves, certain restrictions on distributions under loan documents or required debt or amortization payments.

        To the extent that capital is not available to acquire properties, profits may not be realized or their realization may be delayed, which could result in an earnings stream that is less predictable than some of our competitors and result in us not meeting our projected earnings and distributable cash flow levels in a particular reporting period. Failure to meet our projected earnings and distributable cash flow levels in a particular reporting period could have an adverse effect on our financial condition and on the market price of our common stock.

        Our charter contains 9.8% ownership limits.    Our charter, subject to certain exceptions, authorizes our directors to take such actions as are necessary and desirable to limit any person to actual or

28


Table of Contents

RISK FACTORS


constructive ownership of no more than 9.8% in value or in number of shares, whichever is more restrictive, of the outstanding shares of our capital stock and no more than 9.8% in value or in number of shares, whichever is more restrictive, of the outstanding shares of our common stock. Our board of directors, in its sole discretion, may exempt a proposed transferee from the ownership limits. However, our board of directors may not grant an exemption from the ownership limits to any proposed transferee whose ownership, direct or indirect, of more than 9.8% of the value or number of our outstanding shares of our common stock could jeopardize our status as a REIT. The ownership limits contained in our charter and the restrictions on ownership of our common stock may delay or prevent a transaction or a change of control that might involve a premium price for our common stock or otherwise be in the best interest of our shareholders. See "Description of Stock—Restrictions on Ownership and Transfer of Stock."

        Our board of directors may create and issue a class or series of preferred stock without shareholder approval.    Our board of directors is empowered under our charter to amend our charter to increase or decrease the aggregate number of shares of our common stock or the number of shares of stock of any class or series that we have authority to issue, to designate and issue from time to time one or more classes or series of preferred stock and to classify or reclassify any unissued shares of our common stock or preferred stock without shareholder approval. Our board of directors may determine the relative rights, preferences and privileges of any class or series of preferred stock issued. As a result, we may issue series or classes of preferred stock with preferences, dividends, powers and rights, voting or otherwise, senior to the rights of holders of our common stock. The issuance of preferred stock could also have the effect of delaying or preventing a change of control transaction that might otherwise be in the best interests of our shareholders.

        Certain provisions in the partnership agreement for our operating partnership may delay or prevent unsolicited acquisitions of us.    Provisions in the partnership agreement for our operating partnership may delay or make more difficult unsolicited acquisitions of us or changes in our control. These provisions could discourage third parties from making proposals involving an unsolicited acquisition of us or change of our control, although some shareholders might consider such proposals, if made, desirable. These provisions include, among others:

        Any potential change of control transaction may be further limited as a result of provisions of the partnership unit designation for the LTIP units, which require us to preserve the rights of LTIP unit holders and may restrict us from amending the partnership agreement for our operating partnership in a manner that would have an adverse effect on the rights of LTIP unit holders.

        Certain provisions of Maryland law could inhibit changes in control.    Certain provisions of the MGCL may have the effect of inhibiting a third party from making a proposal to acquire us or impeding a change of control under circumstances that otherwise could provide our shareholders with

the opportunity to realize a premium over the then-prevailing market price of our common stock, including:

        We have elected to opt out of these provisions of the MGCL, in the case of the business combination provisions of the MGCL, by resolution of our board of directors, and in the case of the control share provisions of the MGCL, pursuant to a provision in our bylaws. However, only upon the approval of our stockholders, our board of directors may by resolution elect to repeal the foregoing opt-outs from the business combination provisions of the MGCL and we may, only upon the approval of our stockholders, by amendment to our bylaws, opt in to the control share provisions of the MGCL in the future.

        Additionally, Title 8, Subtitle 3 of the MGCL, permits our board of directors, without shareholder approval and regardless of what is currently provided in our charter or our bylaws, to implement takeover defenses, some of which (for example, a classified board) we do not currently have. These provisions may have the effect of inhibiting a third party from making an acquisition proposal for our company or of delaying, deferring or preventing a change in control of our company under circumstances that otherwise could provide the holders of our common stock with the opportunity to realize a premium over the then-current market price.

        Our charter, bylaws, the partnership agreement for our operating partnership and Maryland law also contain other provisions that may delay, defer or prevent a transaction or a change of control that might involve a premium price for our common stock or otherwise be in the best interest of our shareholders. See "Certain Provisions of Maryland Law and of Our Charter and Bylaws—Our Board of Directors," "—Business Combinations," "—Control Share Acquisitions," "—Maryland Unsolicited Takeovers Act," "—Advance Notice of Director Nominations and New Business" and "Our Operating Partnership and the Partnership Agreement."

        In connection with this offering, we are entering into employment agreements with Messrs. Butcher, Sullivan, Mecke and King and Ms. Arnone. These employment agreements provide that each executive may terminate his or her employment and, under certain conditions, receive severance based on            or             times (depending on the officer) the annual total of salary and bonus. In addition, their incentive compensation such as LTIP units or restricted shares of common stock grants may vest. In the case of certain terminations, they would not be restricted from competing

        The compensation committee of our board of directors is responsible for overseeing our compensation and employee benefit plans and practices, including our executive compensation plans and our incentive compensation and equity-based compensation plans. Our compensation committee has significant discretion in structuring compensation packages and may make compensation decisions based on any number of factors. As a result, compensation awards may not be tied to or correspond with improved financial results at our company or the share price of our common stock.

        In the past, we have reported our results to the investors in our predecessor business on a fund-by-fund basis. We have generally maintained separate systems and procedures for each fund, which makes it more difficult for us to evaluate and integrate their systems and procedures on a reliable company-wide basis. In addition, for certain funds we were not required to report our results on a GAAP basis. In connection with our operation as a public company, we will be required to report our operations on a consolidated basis under GAAP and, in some cases, on a property by property basis. We are in the process of implementing an internal audit function and modifying our company-wide systems and procedures in a number of areas to enable us to enhance our reporting on a consolidated basis under GAAP as we continue the process of integrating the financial reporting of our predecessor. If we fail to implement proper overall business controls, including as required to integrate our predecessor entities and support our growth, our results of operations could be harmed or we could fail to meet our reporting obligations.

        Our board of directors has overall authority to oversee our operations and determine our major corporate policies. This authority includes significant flexibility. For example, our board of directors can do the following:

RISK FACTORS


        Any of these actions could increase our operating expenses, impact our ability to make distributions or reduce the value of our assets without giving you, as a shareholder, the right to vote.

        Maryland law provides that a director or officer has no liability in that capacity if he or she performs his or her duties in good faith, in a manner he or she reasonably believes to be in our best interests and with the care that an ordinarily prudent person in a like position would use under similar circumstances. In addition, our charter eliminates our directors' and officers' liability to us and our shareholders for money damages except for liability resulting from actual receipt of an improper benefit or profit in money, property or services or active and deliberate dishonesty established by a final judgment and which is material to the cause of action. Our bylaws require us to indemnify our directors and officers to the maximum extent permitted by Maryland law for liability actually incurred in connection with any proceeding to which they may be made, or threatened to be made, a party, except to the extent that the act or omission of the director or officer was material to the matter giving rise to the proceeding and was either committed in bad faith or was the result of active and deliberate dishonesty, the director or officer actually received an improper personal benefit in money, property or services, or, in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful. As a result, we and our shareholders may have more limited rights against our directors and officers than might otherwise exist under common law. In addition, we may be obligated to fund the defense costs incurred by our directors and officers.

General Real Estate Risks

        The investment returns available from equity investments in real estate depend on the amount of income earned and capital appreciation generated by the properties, as well as the expenses incurred in connection with the properties. If our properties do not generate income sufficient to meet operating expenses, including debt service and capital expenditures, then our ability to pay distributions to our shareholders could be adversely affected. In addition, there are significant expenditures associated with an investment in real estate (such as mortgage payments, real estate taxes and maintenance costs) that generally do not decline when circumstances reduce the income from the property. Income from and the value of our properties may be adversely affected by:

32


Table of Contents

RISK FACTORS


        In addition, periods of economic slowdown or recession, rising interest rates or declining demand for real estate, or public perception that any of these events may occur, would result in a general decrease in rents or an increased occurrence of defaults under existing leases, which would adversely affect our financial condition and results of operations. Future terrorist attacks may result in declining economic activity, which could reduce the demand for, and the value of, our properties. To the extent that future attacks impact our tenants, their businesses similarly could be adversely affected, including their ability to continue to honor their existing leases.

        For these and other reasons, we cannot assure you that we will be profitable or that we will realize growth in the value of our real estate properties.

        We compete with other owners, operators and developers of real estate, some of which own properties similar to ours in the same markets and submarkets in which our properties are located. If our competitors offer space at rental rates below current market rates or below the rental rates we currently charge our tenants, we may lose potential tenants, and we may be pressured to reduce our rental rates below those we currently charge in order to retain tenants when our tenants' leases expire. As a result, our financial condition, cash flows, cash available for distribution, trading price of our common stock and ability to satisfy our debt service obligations could be materially adversely affected.

RISK FACTORS


        Our results of operations, cash flows and the value of our common stock would be adversely affected if we are unable to lease, on economically favorable terms, a significant amount of space in our operating properties. As of June 30, 2010, leases with respect to 36.4% of our total annualized rent will expire on or before December 31, 2013. We cannot assure you expiring leases will be renewed or that our properties will be re-leased at base rental rates equal to or above the current average base rental rates. In addition, the number of vacant or partially vacant industrial properties in a market or submarket could adversely affect our ability to re-lease the space at attractive rental rates.

        A property may incur a vacancy either by the continued default of a tenant under its lease or the expiration of one of our leases. In addition, certain of the properties we acquire may have some level of vacancy at the time of closing. Certain of our properties may be specifically suited to the particular needs of a tenant. We may have difficulty obtaining a new tenant for any vacant space we have in our properties. If the vacancy continues for a long period of time, we may suffer reduced revenue resulting in less cash available to be distributed to shareholders. In addition, the resale value of a property could be diminished because the market value of a particular property will depend principally upon the value of the leases of such property.

        When a tenant at one of our properties does not renew its lease or otherwise vacates its space in one of our buildings, it is likely that, in order to attract one or more new tenants, we will be required to expend funds to construct new tenant improvements in the vacated space. We cannot assure you that we will have adequate sources of funding available to us for such purposes in the future.

        If a tenant becomes bankrupt or insolvent, that could diminish the income we receive from that tenant's leases. Our tenants may experience downturns in their operating results due to adverse changes to their business or economic conditions, and those tenants that are highly leveraged may have a higher possibility of filing for bankruptcy or insolvency. We may not be able to evict a tenant solely because of its bankruptcy. On the other hand, a bankruptcy court might authorize the tenant to terminate its leases with us. If that happens, our claim against the bankrupt tenant for unpaid future rent would be an unsecured prepetition claim subject to statutory limitations, and therefore such amounts received in bankruptcy are likely to be substantially less than the remaining rent we otherwise were owed under the leases. In addition, any claim we have for unpaid past rent could be substantially less than the amount owed. If the lease for such a property is rejected in bankruptcy, our revenue would be reduced and could cause us to reduce distributions to shareholders.

RISK FACTORS


        Real estate investments are not as liquid as other types of investments, and this lack of liquidity may limit our ability to react promptly to changes in economic or other conditions. In addition, significant expenditures associated with real estate investments, such as mortgage payments, real estate taxes and maintenance costs, are generally not reduced when circumstances cause a reduction in income from the investments. In addition, we intend to comply with the safe harbor rules relating to the number of properties that can be disposed of in a year, the tax bases and the costs of improvements made to these properties, and other items that enable a REIT to avoid punitive taxation on the sale of assets. Thus, our ability at any time to sell assets or contribute assets to property funds or other entities in which we have an ownership interest may be restricted. This lack of liquidity may limit our ability to vary our portfolio promptly in response to changes in economic or other conditions and, as a result, could adversely affect our financial condition, results of operations, cash flows and our ability to pay distributions on, and the market price of, our common stock.

        We have acquired, and may continue to acquire, properties in markets that are new to us. When we acquire properties located in these markets, we may face risks associated with a lack of market knowledge or understanding of the local economy, forging new business relationships in the area and unfamiliarity with local government and permitting procedures.

        We attempt to ensure that all of our properties are adequately insured to cover casualty losses. However, there are certain losses, including losses from floods, earthquakes, acts of war, acts of terrorism or riots, that are not generally insured against or that are not generally fully insured against because it is not deemed economically feasible or prudent to do so. In addition, changes in the cost or availability of insurance could expose us to uninsured casualty losses. In the event that any of our properties incurs a casualty loss that is not fully covered by insurance, the value of our assets will be reduced by the amount of any such uninsured loss, and we could experience a significant loss of capital invested and potential revenue in these properties and could potentially remain obligated under any recourse debt associated with the property. Moreover, we, as the indirect general partner of our operating partnership, generally will be liable for all of our operating partnership's unsatisfied recourse obligations, including any obligations incurred by our operating partnership as the general partner of joint ventures. Any such losses could adversely affect our financial condition, results of operations, cash flows and ability to pay distributions on, and the market price of, our common stock. In addition, we may have no source of funding to repair or reconstruct the damaged property, and we cannot assure you that any such sources of funding will be available to us for such purposes in the future. We evaluate our insurance coverage annually in light of current industry practice through an analysis prepared by outside consultants.

        As part of our formation transactions, we will assume existing liabilities of contributed operating companies and liabilities in connection with contributed properties, some of which may be unknown or unquantifiable at the time this offering is consummated. Unknown liabilities might include liabilities for cleanup or remediation of undisclosed environmental conditions beyond the scope of our environmental

RISK FACTORS


insurance coverage, claims of tenants, vendors or other persons dealing with the entities prior to this offering, tax liabilities, and accrued but unpaid liabilities whether incurred in the ordinary course of business or otherwise. As part of our formation transactions, the owners of our predecessor business have only made limited representations and warranties to us regarding the entities, properties and assets that we will own following our formation transactions that survive for a period of one year and agreed to indemnify us and our operating partnership for breaches of such representations subject to specified deductibles and caps, as applicable. Because many liabilities, including tax liabilities, may not be identified within such period, we may have no recourse against any of the owners of our predecessor business for these liabilities.

        In addition, we may in the future acquire properties, or may have previously owned properties, subject to liabilities and without any recourse, or with only limited recourse, with respect to unknown liabilities. As a result, if a liability were asserted against us based on ownership of any of these entities or properties, then we might have to pay substantial sums to settle it, which could adversely affect our cash flows.

        Under various federal, state and local environmental laws, a current or previous owner or operator of real property may be liable for the cost of removing or remediating hazardous or toxic substances on such property. Such laws often impose liability whether or not the owner or operator knew of, or was responsible for, the presence of such hazardous or toxic substances. Even if more than one person may have been responsible for the contamination, each person covered by the environmental laws may be held responsible for all of the clean-up costs incurred. In addition, third parties may sue the owner or operator of a site for damages based on personal injury, natural resources or property damage or other costs, including investigation and clean-up costs, resulting from the environmental contamination. The presence of hazardous or toxic substances on one of our properties, or the failure to properly remediate a contaminated property, could give rise to a lien in favor of the government for costs it may incur to address the contamination, or otherwise adversely affect our ability to sell or lease the property or borrow using the property as collateral. Environmental laws also may impose restrictions on the manner in which property may be used or businesses may be operated. A property owner who violates environmental laws may be subject to sanctions which may be enforced by governmental agencies or, in certain circumstances, private parties. In connection with the acquisition and ownership of our properties, we may be exposed to such costs. The cost of defending against environmental claims, of compliance with environmental regulatory requirements or of remediating any contaminated property could materially adversely affect our business, assets or results of operations and, consequently, amounts available for distribution to our shareholders.

        Environmental laws in the United States also require that owners or operators of buildings containing asbestos properly manage and maintain the asbestos, adequately inform or train those who may come into contact with asbestos and undertake special precautions, including removal or other abatement, in the event that asbestos is disturbed during building renovation or demolition. These laws may impose fines and penalties on building owners or operators who fail to comply with these requirements and may allow third parties to seek recovery from owners or operators for personal injury associated with exposure to asbestos. Some of our properties contain asbestos-containing building materials.

        We invest in properties historically used for industrial, manufacturing and commercial purposes. Some of these properties contain, or may have contained, underground storage tanks for the storage of petroleum products and other hazardous or toxic substances. All of these operations create a potential

RISK FACTORS



for the release of petroleum products or other hazardous or toxic substances. Some of our properties are adjacent to or near other properties that have contained or currently contain underground storage tanks used to store petroleum products or other hazardous or toxic substances. In addition, certain of our properties are on or are adjacent to or near other properties upon which others, including former owners or tenants of our properties, have engaged, or may in the future engage, in activities that may release petroleum products or other hazardous or toxic substances.

        From time to time, we may acquire properties, or interests in properties, with known adverse environmental conditions where we believe that the environmental liabilities associated with these conditions are quantifiable and that the acquisition will yield a superior risk-adjusted return. In such an instance, we underwrite the costs of environmental investigation, clean-up and monitoring into the cost. Further, in connection with property dispositions, we may agree to remain responsible for, and to bear the cost of, remediating or monitoring certain environmental conditions on the properties.

        Preliminary assessments of environmental conditions at a property that meet certain specifications are often referred to as "Phase I environmental site assessments" or "Phase I environmental assessments." They are intended to discover and evaluate information regarding the environmental condition of the surveyed property and surrounding properties. Phase I environmental assessments generally include an historical review, a public records review, an investigation of the surveyed site and surrounding properties, and preparation and issuance of a written report, but do not include soil sampling or subsurface investigations and typically do not include an asbestos survey. No such assessments have been updated on our properties for purposes of this offering, and, as of June 30, 2010, approximately 25.8% of our properties have environmental assessments which are more than three years old. Material environmental conditions, liabilities or compliance concerns may arise after the environmental assessment has been completed. Moreover, there can be no assurance that:

        Under the Americans with Disabilities Act of 1990, as amended (the "ADA"), places of public accommodation must meet certain federal requirements related to access and use by disabled persons. Noncompliance could result in the imposition of fines by the federal government or the award of damages to private litigants. If we are required to make unanticipated expenditures to comply with the ADA, including removing access barriers, then our cash flows and the amounts available for distributions to our shareholders may be adversely affected. While we believe that our properties are currently in material compliance with these regulatory requirements, the requirements may change or new requirements may be imposed that could require significant unanticipated expenditures by us that will affect our cash flows and results of operations.

        We own one of our properties through a leasehold interest in the land underlying the building and we may acquire additional buildings in the future that are subject to similar ground leases. As lessee under a ground lease, we are exposed to the possibility of losing the property upon expiration, or an

37


Table of Contents

RISK FACTORS


earlier breach by us, of the ground lease, which may have an adverse effect on our business, financial condition and results of operations, our ability to make distributions to our shareholders and the trading price of our common stock.

        In the future, our ground leases may contain certain provisions that may limit our ability to sell certain of our properties. In addition, in the future, in order to assign or transfer our rights and obligations under certain of our ground leases, we may be required to obtain the consent of the landlord which, in turn, could adversely impact the price realized from any such sale.

        We also own one property that benefits from payment in lieu of tax ("PILOT") programs and to facilitate such tax treatment our ownership in this property is structured as a leasehold interest with the relevant municipality serving as lessor. With respect to such arrangement, we have the right to purchase the fee interest in the property for a nominal purchase price, so the risk factors set forth above for traditional ground leases are mitigated by our ability to convert such leasehold interest to fee interest. In the event of such a conversion of our ownership interest, however, any preferential tax treatment offered by the PILOT program will be lost.

        We expect to hold the various real properties in which we invest until such time as we decide that a sale or other disposition is appropriate given our investment objectives. Our ability to dispose of properties on advantageous terms depends on factors beyond our control, including competition from other sellers and the availability of attractive financing for potential buyers of our properties. We cannot predict the various market conditions affecting real estate investments which will exist at any particular time in the future. Due to the uncertainty of market conditions which may affect the future disposition of our properties, we cannot assure you that we will be able to sell our properties at a profit in the future. Accordingly, the extent to which you will receive cash distributions and realize potential appreciation on our real estate investments will be dependent upon fluctuating market conditions.

        Furthermore, we may be required to expend funds to correct defects or to make improvements before a property can be sold. We cannot assure you that we will have funds available to correct such defects or to make such improvements.

        We may acquire properties through contracts that could restrict our ability to dispose of the property for a period of time. These "lock-out" provisions could affect our ability to turn our investments into cash and could affect cash available for distributions to you. Lock-out provisions could also impair our ability to take actions during the lock-out period that would otherwise be in the best interest of our shareholders and, therefore, may have an adverse impact on the value of our common stock relative to the value that would result if the lock-out provisions did not exist.

        If we decide to sell any of our properties, we presently intend to use our best efforts to sell them for cash. However, in some instances we may sell our properties by providing financing to purchasers. If we provide financing to purchasers, we will bear the risk that the purchaser may default, which could negatively impact our cash distributions to shareholders and result in litigation and related expenses.

38

RISK FACTORS


Even in the absence of a purchaser default, the distribution of the proceeds of sales to our shareholders, or their reinvestment in other assets, will be delayed until the promissory notes or other property we may accept upon a sale are actually paid, sold, refinanced or otherwise disposed of.

Risks Related to Our Debt Financings

        Our charter and bylaws do not limit the amount or percentage of indebtedness that we may incur, and we are subject to risks normally associated with debt financing, including the risk that our cash flows will be insufficient to meet required payments of principal and interest. There can be no assurance that we will be able to refinance any maturing indebtedness, that such refinancing would be on terms as favorable as the terms of the maturing indebtedness or that we will be able to otherwise obtain funds by selling assets or raising equity to make required payments on maturing indebtedness.

        In particular, loans obtained to fund property acquisitions will generally be secured by first mortgages on such properties. If we are unable to make our debt service payments as required, a lender could foreclose on the property or properties securing its debt. This could cause us to lose part or all of our investment, which in turn could cause the value of our common stock and distributions payable to shareholders to be reduced. Certain of our existing and future indebtedness is and may be cross-collateralized and, consequently, a default on this indebtedness could cause us to lose part or all of our investment in multiple properties. See "Policies With Respect to Certain Activities—Financing Policies."

        As of June 30, 2010, we had total pro forma outstanding debt of approximately $166.9 million, and we expect that we will incur additional indebtedness in the future. Interest we pay reduces our cash available for distributions. We have entered into interest rate swaps to mitigate the risk of increasing interest rates for our $73.0 million in variable rate debt. Since we have incurred and may continue to incur variable rate debt, increases in interest rates raise our interest costs, which reduces our cash flows and our ability to make distributions to you. If we are unable to refinance our indebtedness at maturity or meet our payment obligations, the amount of our distributable cash flows and our financial condition would be adversely affected, and we may lose the property securing such indebtedness. In addition, if we need to repay existing debt during periods of rising interest rates, we could be required to liquidate one or more of our investments in properties at times which may not permit realization of the maximum return on such investments.

        The terms of our mortgage loans require us to comply with loan-to-collateral-value ratios, debt service coverage ratios and, in the case of an event of default, limitations on the ability of our subsidiaries that are borrowers under our mortgage loans to make distributions to us or our other subsidiaries. In addition, we are currently negotiating with several financial institutions regarding the establishment of a $             million corporate credit facility (subject to increase to $             million under certain circumstances) that we anticipate will close contemporaneously with this offering. Any facility we obtain will likely include a number of additional customary financial and other covenants. Any of our existing loan covenants or future credit facility covenants may limit our flexibility in our

RISK FACTORS


operations and prevent us from making distributions to our shareholders, and breaches of these covenants could result in defaults under the instruments governing the applicable indebtedness even if we have satisfied our payment obligations.

        As of June 30, 2010, we had certain secured loans that are cross-collateralized by multiple properties. If we default on any of these loans we may then be required to repay such indebtedness, together with applicable prepayment charges, to avoid foreclosure on all cross-collateralized properties within the applicable pool. Moreover, any future corporate credit facility of ours may contain certain cross-default provisions which are triggered in the event that our other material indebtedness is in default. These cross-default provisions may require us to repay or restructure the facility in addition to any mortgage or other debt that is in default. If our properties were foreclosed upon, or if we are unable to refinance our indebtedness at maturity or meet our payment obligations, the amount of our distributable cash flows and our financial condition would be adversely affected.

        We are a holding company and conduct all of our operations through our operating partnership. We do not have, apart from our ownership of our operating partnership, any independent operations. As a result, we will rely on distributions from our operating partnership to pay any dividends we might declare on our common stock. We will also rely on distributions from our operating partnership to meet our debt service and other obligations, including our obligations to make distributions required to maintain our REIT status. The ability of subsidiaries of our operating partnership to make distributions to the operating partnership, and the ability of our operating partnership to make distributions to us in turn, will depend on their operating results and on the terms of any loans that encumber the properties owned by them. Such loans may contain lockbox arrangements, reserve requirements, financial covenants and other provisions that restrict the distribution of funds. In the event of a default under these loans, the defaulting subsidiary would be prohibited from distributing cash. For example, our subsidiaries are party to mortgage loans that prohibit, in the event of default, their distribution of any cash to a related party, including our operating partnership. As a result, a default under any of these loans by the borrower subsidiaries could cause us to have insufficient cash to make distributions on our common stock required to maintain our REIT status.

        Some of our financing arrangements require us to make a lump-sum or "balloon" payment at maturity. Our ability to make a balloon payment at maturity is uncertain and may depend upon our ability to obtain additional financing or our ability to sell the property. At the time the balloon payment is due, we may or may not be able to refinance the existing financing on terms as favorable as the original loan or sell the property at a price sufficient to make the balloon payment. The effect of a refinancing or sale could affect the rate of return to shareholders and the projected time of disposition of our assets. In addition, payments of principal and interest made to service our debts may leave us with insufficient cash to pay the distributions that we are required to pay to maintain our qualification as a REIT.

        If mortgage debt is unavailable at reasonable rates, we may not be able to finance the purchase of properties. In addition, we run the risk of being unable to refinance mortgage debt when the loans come due or of being unable to refinance such debt on favorable terms. If interest rates are higher when we refinance such debt, our income could be reduced. We may be unable to refinance such debt

RISK FACTORS


at appropriate times, which may require us to sell properties on terms that are not advantageous to us or could result in the foreclosure of such properties. If any of these events occur, our cash flows would be reduced. This, in turn, would reduce cash available for distribution to you and may hinder our ability to raise more capital by issuing more stock or by borrowing more money.

        We use various derivative financial instruments to provide a level of protection against interest rate risks, but no hedging strategy can protect us completely. These instruments involve risks, such as the risk that the counterparties may fail to honor their obligations under these arrangements, that these arrangements may not be effective in reducing our exposure to interest rate changes and that a court could rule that such agreements are not legally enforceable. These instruments may also generate income that may not be treated as qualifying REIT income for purposes of the 75% or 95% REIT income tests. In addition, the nature and timing of hedging transactions may influence the effectiveness of our hedging strategies. Poorly designed strategies or improperly executed transactions could actually increase our risk and losses. Moreover, hedging strategies involve transaction and other costs. We cannot assure you that our hedging strategy and the derivatives that we use will adequately offset the risk of interest rate volatility or that our hedging transactions will not result in losses that may reduce the overall return on your investment.

Risks Related to this Offering

        The purchase price per share of our common stock offered pursuant to this prospectus reflects the result of negotiations between us and the representatives of the underwriters. The purchase price may not accurately reflect the future value of our company, and the offering price may not be realized upon any subsequent disposition of the shares.

        In the future, we may attempt to increase our capital resources by making offerings of debt or additional offerings of equity securities, including commercial paper, senior or subordinated notes and series of preferred stock or common stock. Upon liquidation, holders of our debt securities and shares of preferred stock, if any, and lenders with respect to other borrowings will receive a distribution of our available assets prior to the holders of our common stock. Additional equity offerings may dilute the holdings of our existing shareholders or reduce the market price of our common stock, or both. Preferred stock, if issued, could have a preference on liquidating distributions or a preference on dividend payments or both that could limit our ability to make a dividend distribution to the holders of our common stock. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, holders of our common stock bear the risk of our future offerings reducing the market price of our common stock and diluting their stock holdings in us.

RISK FACTORS


        Sales of substantial amounts of shares of our common stock in the public market, or upon exchange of common units or exercise of any options, or the perception that such sales might occur could adversely affect the market price of our common stock. The exchange of common units for common stock, the exercise of any stock options or the vesting of any restricted stock granted to certain directors, executive officers and other employees under our 2010 Equity Incentive Plan, the issuance of our common stock or common units in connection with property, portfolio or business acquisitions and other issuances of our common stock or common units could have an adverse effect on the market price of the shares of our common stock. Also, continuing investors that will hold shares of our outstanding common stock and            common units on a pro forma basis are parties to agreements that provide for registration rights. The exercise of these registration rights could depress the price of our common stock. The existence of shares of our common stock reserved for issuance as restricted shares or upon exchange of options or common units may adversely affect the terms upon which we may be able to obtain additional capital through the sale of equity securities. In addition, future sales by us of our common stock may be dilutive to existing shareholders.

        Our executive officers and our directors and the owners of the management company, Fund III, Fund IV and STAG GI have entered into lock-up agreements that, subject to exceptions, prohibit them from selling, pledging, transferring or otherwise disposing of our common stock or securities convertible into our common stock for a period of 12 months after the date of this prospectus. The representatives of the underwriters may, in their discretion, release all or any portion of the common stock subject to the lock-up agreements with our directors and officers and the owners of the management company, Fund III, Fund IV and STAG GI at any time without notice or shareholder approval. If the restrictions under the lock-up agreements are waived or terminated, up to approximately            shares of common stock, including securities convertible into our common stock, will be available for sale into the market, subject only to applicable securities rules and regulations and, in some cases, vesting requirements, which could reduce the market price for our common stock.

        Currently, there is no established trading market for our common stock. We will apply for listing on the New York Stock Exchange ("NYSE") under the symbol "STIR" to be effective upon completion of this offering. We cannot assure you that our listing application will be accepted or that, if accepted, an active trading market for our common stock will develop after the offering or if one does develop, that it will be sustained.

        Even if an active trading market develops, the market price of our common stock may be volatile. In addition, the trading volume in our common stock may fluctuate and cause significant price variations to occur. If the market price of our common stock declines, you may be unable to resell your shares at or above the initial public offering price. We cannot assure you that the market price of our common stock will not fluctuate or decline significantly in the future. Some of the factors that could affect our stock price or result in fluctuations in the price or trading volume of our common stock include:

RISK FACTORS


        In addition, the stock market has experienced price and volume fluctuations that have affected the market prices of many companies in industries similar or related to ours and may have been unrelated to operating performances of these companies. These broad market fluctuations could reduce the market price of our common stock.

        As of June 30, 2010, the pro forma net tangible book value of the assets to be acquired by us in our formation transactions was approximately $       million, or $      per share of our common stock held by our continuing investors, assuming the exchange of common units for shares of our common stock on a one-for-one basis. As a result, the pro forma net tangible book value per share of our common stock after the consummation of our formation transactions and this offering will be less than the initial public offering price. The purchasers of our common stock offered hereby will experience immediate and substantial dilution of $      per share in the pro forma net tangible book value per share of our common stock.

        One of the factors that will influence the price of our common stock will be the dividend yield on our common stock (as a percentage of the price of our common stock) relative to market interest rates. An increase in market interest rates may lead prospective purchasers of our common stock to expect a higher dividend yield and, if we are unable to pay such yield, the market price of our common stock could decrease.

        The market value of the equity securities of a REIT is based primarily upon the market's perception of the REIT's growth potential and its current and potential future cash distributions, whether from operations, sales or refinancings, and is secondarily based upon the real estate market value of the underlying assets. For that reason, our common stock may trade at prices that are higher or lower than our net asset value per share. To the extent we retain operating cash flow for investment purposes, working capital reserves or other purposes, these retained funds, while increasing the value of our underlying assets, may not correspondingly increase the market price of our common stock. Our failure to meet the market's expectations with regard to future earnings and cash distributions likely would adversely affect the market price of our common stock.

        STAG Predecessor Group had historical net losses of $2.0 million, $0.9 million, $5.6 million, $7.7 million and $2.0 million for the six months ended June 30, 2010 and 2009 and the years ended December 31, 2009, 2008 and 2007, respectively. STAG Predecessor Group had historical accumulated deficits after effects of depreciation and amortization of $5.2 million and $1.5 million as of June 30, 2010 and December 31, 2009, respectively. There can be no assurance that we will not continue to incur net losses in the future, which could adversely affect our ability to service our indebtedness and our ability to pay dividends or make distributions, any of which could adversely affect the trading price of our common stock.

        Following this offering, we will become subject to reporting and other obligations under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), including the requirements of Section 404 of the Sarbanes-Oxley Act. Section 404 requires annual management assessments of the effectiveness of our internal controls over financial reporting and a report by our independent registered public accounting firm addressing these assessments. These reporting and other obligations will place significant demands on our management, administrative, operational, internal audit and accounting resources and will cause us to incur significant expenses. We may need to upgrade our systems or create new systems; implement additional financial and management controls, reporting systems and procedures; expand our internal audit function; and hire additional accounting, internal audit and finance staff. If we are unable to accomplish these objectives in a timely and effective fashion, our ability to comply with the financial reporting requirements and other rules that apply to reporting companies could be impaired. Any failure to achieve and maintain effective internal controls could have a material adverse effect on our business, operating results and stock price.

U.S. Federal Income Tax Risks

        Our qualification as a REIT will depend upon our ability to meet requirements regarding our organization and ownership, distributions of our income, the nature and diversification of our income and assets and other tests imposed by the Code. If we fail to qualify as a REIT for any taxable year after electing REIT status, we will be subject to U.S. federal income tax on our taxable income at corporate rates. In addition, we would generally be disqualified from treatment as a REIT for the four taxable years following the year of losing our REIT status. Losing our REIT status would reduce our net earnings available for investment or distribution to shareholders because of the additional tax liability. In addition, dividends to shareholders would no longer qualify for the dividends-paid deduction and we would no longer be required to make distributions. If this occurs, we might be required to borrow funds or liquidate some investments in order to pay the applicable tax. For a discussion of the REIT qualification tests and other considerations relating to our election to be taxed as REIT, see "U.S. Federal Income Tax Considerations."

        In the future, we may institute a dividend reinvestment plan, which would allow our shareholders to acquire additional shares of common stock by automatically reinvesting their cash dividends. If our shareholders participate in a dividend reinvestment plan, they will be deemed to have received, and for

RISK FACTORS


income tax purposes will be taxed on, the amount reinvested in shares of our common stock to the extent the amount reinvested was not a tax-free return of capital. In addition, our shareholders will be treated for tax purposes as having received an additional distribution to the extent the shares are purchased at a discount to fair market value. As a result, unless a shareholder is a tax-exempt entity, it may have to use funds from other sources to pay its tax liability on the value of the shares of common stock received.

        Even if we qualify as a REIT for U.S. federal income tax purposes, we may be subject to some U.S. federal, state and local taxes on our income or property. For example:

        We intend to make distributions to our shareholders to comply with the REIT requirements of the Code.

        From time to time, we may generate taxable income greater than our income for financial reporting purposes, or our taxable income may be greater than our cash flow available for distribution to shareholders (for example, where a borrower defers the payment of interest in cash pursuant to a contractual right or otherwise). If we do not have other funds available in these situations we could be required to borrow funds, sell investments at disadvantageous prices or find another alternative source of funds to make distributions sufficient to enable us to pay out enough of our taxable income to satisfy the REIT distribution requirement and to avoid corporate income tax and the 4% excise tax in a particular year. These alternatives could increase our costs or reduce our equity. Thus, compliance with the REIT requirements may hinder our ability to operate solely on the basis of maximizing profits.

        To qualify as a REIT, we must satisfy certain tests on an ongoing basis concerning, among other things, the sources of our income, nature of our assets and the amounts we distribute to our shareholders. We may be required to make distributions to shareholders at times when it would be more advantageous to reinvest cash in our business or when we do not have funds readily available for

distribution. Compliance with the REIT requirements may hinder our ability to operate solely on the basis of maximizing profits and the value of our shareholders' investment.

        We expect to purchase real properties and lease them back to the sellers of such properties. While we will use commercially reasonable efforts to structure any such sale-leaseback transaction such that the lease will be characterized as a "true lease" for tax purposes, thereby allowing us to be treated as the owner of the property for U.S. federal income tax purposes, we cannot assure you that the Internal Revenue Service ("IRS") will not challenge such characterization. In the event that any such sale-leaseback transaction is challenged and recharacterized as a financing transaction or loan for U.S. federal income tax purposes, deductions for depreciation and cost recovery relating to such property would be disallowed. If a sale-leaseback transaction were so recharacterized, we might fail to satisfy the REIT qualification "asset tests" or "income tests" and, consequently, lose our REIT status effective with the year of recharacterization. Alternatively, the amount of our REIT taxable income could be recalculated which might also cause us to fail to meet the distribution requirement for a taxable year.

        We may be deemed to be, or make investments in entities that own or are themselves deemed to be taxable mortgage pools. Similarly, certain of our securitizations or other borrowings could be considered to result in the creation of a taxable mortgage pool for U.S. federal income tax purposes. As a REIT, provided that we own 100% of the equity interests in a taxable mortgage pool, we generally would not be adversely affected by the characterization of the securitization as a taxable mortgage pool. Certain categories of shareholders, however, such as foreign shareholders eligible for treaty or other benefits, shareholders with net operating losses, and certain tax-exempt shareholders that are subject to unrelated business income tax, could be subject to increased taxes on a portion of their dividend income from us that is attributable to the taxable mortgage pool. In addition, to the extent that our stock is owned by tax-exempt "disqualified organizations," such as certain government-related entities that are not subject to tax on unrelated business income, we will incur a corporate-level tax on a portion of our income from the taxable mortgage pool. In that case, we are authorized to reduce and intend to reduce the amount of our distributions to any disqualified organization whose stock ownership gave rise to the tax by the amount of such tax paid by us that is attributable to such shareholder's ownership. Moreover, we would be precluded from selling equity interests in these securitizations to outside investors, or selling any debt securities issued in connection with these securitizations that might be considered to be equity interests for U.S. federal income tax purposes. These limitations may prevent us from using certain techniques to maximize our returns from securitization transactions.

        The rules dealing with federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Department of the Treasury. Changes to the tax laws, with or without retroactive application, could adversely affect our shareholders or us. We cannot predict how changes in the tax laws might affect our shareholders or us. New legislation, Treasury Regulations, administrative interpretations or court decisions could significantly and negatively affect our ability to qualify as a REIT or the federal income tax consequences of such qualification.

RISK FACTORS


        As a result of our formation transactions described above, the contributors expect to defer approximately $       million of taxable income and taxable gain. The contribution transactions are expected to be tax free, in whole or in part, to us, our operating partnership and the contributors. Our operating partnership will have a carryover tax basis in the assets of the limited liability companies acquired by us by contribution such that our basis will be the same as the basis immediately before our formation transactions, adjusted upward by the gain, if any, recognized by the contributors. As a result of the contributions, we will have substantial built-in taxable income in our assets immediately after our formation transactions.

        We intend to take the position that each of the contributions of the interests in the limited liability companies qualify as a tax-free transaction, in whole or in part, under the Code. To the extent any of these contributions does not so qualify, then the contribution would be treated as a taxable asset sale in which the contributors would be required to recognize taxable gain. If the contribution is treated as a taxable event, our adjusted tax basis in the assets of the limited liability companies is expected to equal the then fair market value of the consideration paid for such assets.

ERISA Risks

        Fiduciaries of employee benefit plans subject to the Employee Retirement Income Security Act of 1974, as amended ("ERISA") should take into account their fiduciary responsibilities in connection with a decision to invest in our common stock. If such fiduciaries breach their responsibilities, including (among other things) the responsibility to act prudently, to diversify the plan's assets, and to follow plan documents and investment policies, they may be held liable for plan losses and may be subject to civil or criminal penalties and excise taxes. Similar consequences may result if a plan's investment in shares of our stock constitutes a so-called "prohibited transaction" under ERISA. Plans or arrangements that are not subject to ERISA, such as individual retirement accounts, may be subject to Section 4975 of the Code, which contains similar prohibited transaction rules.

        Although it is intended that our underlying assets and our operating partnership's underlying assets will not constitute "plan assets" of ERISA plans within the meaning of Department of Labor regulations and Section 3(42) of ERISA, there can be no assurance in this regard. If our assets or our operating partnership's assets constitute plan assets under ERISA, certain transactions in which we might normally engage could constitute prohibited transactions under ERISA or the Code. If our assets or our operating partnership's assets are plan assets, our managers may be fiduciaries under ERISA.

        Governmental employee benefit plans and certain church plans are exempt from ERISA, but these plans may be subject to federal, state or local laws that are similar to the ERISA laws and regulations discussed above.

USE OF PROCEEDS

        We estimate that the net proceeds we will receive from the sale of shares of our common stock in this offering will be approximately $             million (or approximately $             million if the underwriters exercise their overallotment option in full), in each case assuming a public offering price of $            per share, which is the mid-point of the range set forth on the cover of this prospectus, and after deducting underwriting discounts and commissions of approximately $             million (or approximately $             million if the underwriters exercise their overallotment option in full) and estimated organizational and offering expenses of approximately $             million payable by us. We will contribute the net proceeds of this offering to our operating partnership in exchange for common units in our operating partnership.

        We expect our operating partnership will use the net proceeds as follows:

        If the underwriters exercise their overallotment option in full, we expect to use the additional       million of net proceeds for general corporate purposes, including acquisitions of real estate assets.

USE OF PROCEEDS


        The debt repayments described above are estimated based on principal and related accrued interest outstanding as of June 30, 2010. The actual amounts of the debt repayments will depend on the principal and related accrued interest outstanding at the time of payment and may be greater than or less than our estimates above.

        Pending application of cash proceeds, we intend to invest the net proceeds temporarily in interest-bearing, short-term investment-grade securities, money-market accounts or checking accounts, which are consistent with our intention to qualify for taxation as a REIT. Such investments may include, for example, government and government agency certificates, certificates of deposit, interest-bearing bank deposits and mortgage loan participations. These initial investments are expected to provide a lower net return than we will seek to achieve from investments in our properties.

DISTRIBUTION POLICY

        We intend to elect and qualify to be treated as a REIT for U.S. federal income tax purposes commencing with our taxable year ending December 31, 2010. U.S. federal income tax law generally requires that a REIT distribute annually at least 90% of its REIT taxable income, determined without regard to the deduction for dividends paid and excluding net capital gains. We will not be required to make distributions with respect to income derived from the activities conducted through STAG Industrial TRS, Inc. (our "TRS") that is not distributed to us. Our TRS is the entity through which we will provide any third-party management and advisory services, potentially including management services provided to Fund II, Fund III and Fund IV, unless such services can be provided without jeopardizing our REIT status. To the extent our TRS's income is not distributed and is instead reinvested with the operations of our TRS, the value of our equity interest in our TRS will increase. The aggregate value of the securities that we hold in our TRS may not exceed 25% of the total value of our gross assets. In part because of restrictions applicable to us as a REIT, distributions from our TRS to us will not exceed 25% of our gross income with respect to any given taxable year.

        We are a newly formed company that has not commenced operations and, as a result, we have not paid distributions as of the date of this prospectus. To satisfy the requirements to qualify as a REIT and generally not be subject to U.S. federal income tax, we intend to make quarterly distributions of all or substantially all of our taxable income to holders of our common stock out of assets legally available therefor. We intend to pay a pro rata initial distribution with respect to the period commencing on the completion of this offering and ending at the last day of the then-current fiscal quarter, based on a distribution of $      per share for a full quarter. On an annualized basis, this would be $      per share, or an annual distribution rate of approximately    %, based on the midpoint of the range set forth on the cover page of this prospectus. We estimate that this initial annual distribution rate will represent approximately      % of estimated cash available for distribution to our common shareholders for the 12 months ending June 30, 2011. Our intended initial annual distribution rate has been established based on our estimate of cash available for distribution for the 12 months ending June 30, 2011, which we have calculated based on adjustments to our pro forma net income for the 12 months ended June 30, 2010 (after giving effect to the offering and the formation transactions). This estimate was based on our pro forma operating results and does not take into account our growth strategy, nor does it take into account any unanticipated expenditures we may have to make or any debt we may have to incur. In estimating our cash available for distribution for the 12 months ending June 30, 2011, we have made certain assumptions as reflected in the table and footnotes below.

        Our estimate of cash available for distribution does not include the effect of any changes in our working capital. Our estimate also does not reflect the amount of cash estimated to be used for investing activities for acquisition and other activities, other than a reserve for recurring capital expenditures and current contractual tenant improvement or leasing commission costs to be incurred in the 12 months ending June 30, 2011 related to any new leases or lease renewals entered into as of June 30, 2010. It also does not reflect the amount of cash estimated to be used for financing activities, other than scheduled debt principal payments on mortgage and other indebtedness that will be outstanding upon completion of this offering. Any such investing and/or financing activities may have a material effect on our estimate of cash available for distribution. Because we have made the assumptions set forth above in estimating cash available for distribution, we do not intend this estimate to be a projection or forecast of our actual results of operations or our liquidity, and we have estimated cash available for distribution for the sole purpose of determining the amount of our initial annual distribution rate. Our estimate of cash available for distribution should not be considered as an alternative to cash flow from operating activities (computed in accordance with GAAP). In addition, the methodology upon which we made the adjustments described below is not necessarily intended to be a basis for determining future dividends or other distributions.

DISTRIBUTION POLICY


        We intend to maintain our initial distribution rate for the 12-month period following completion of this offering unless our actual results of operations, economic conditions or other factors differ materially from the assumptions used in our estimate. Any future distributions we make will be at the discretion of our board of directors and will depend upon our earnings and financial condition, maintenance of REIT qualification and the applicable provisions of the MGCL and such other factors as our board may determine in its sole discretion. We anticipate that our estimated cash available for distribution will exceed the annual distribution requirements applicable to REITs. However, under some circumstances, we may be required to pay distributions in excess of cash available for distribution in order to meet these distribution requirements and we may need to use the proceeds from future equity and debt offerings, sell assets or borrow funds to make distributions. We have no intention to use the net proceeds from this offering to make distributions nor do we intend to make distributions using shares of common stock. We cannot assure you that our distribution policy will not change in the future. Actual distributions may be significantly different from the expected distributions. For more information regarding risk factors that could materially adversely affect our earnings and financial condition, please see "Risk Factors."

        We anticipate that our distributions generally will be taxable as ordinary income to our shareholders, although a portion of the distributions may be designated by us as qualified dividend income, excess inclusion income, or capital gain or may constitute a return of capital. We will furnish annually to each of our shareholders a statement setting forth distributions paid during the preceding year and their characterization as ordinary income, excess inclusion income, return of capital, qualified dividend income and/or capital gains.

        The following table describes our pro forma net loss before non-controlling interest for the year ended December 31, 2009, and the adjustments we have made thereto in order to estimate our initial cash available for distribution to the holders or our common stock for the 12 months ending June 30, 2011 (dollars in thousands, except per share data). The table reflects our condensed consolidated information, including common units in our operating partnership. Each common unit in our operating

Provision for tenant improvements and leasing commissions includes any current contractual tenant improvement or leasing commission costs to be incurred in the 12 months ending June 30, 2011 related to any new leases or lease renewals entered into as of June 30, 2010. During the 12 months ending June 30, 2011, we expect to have additional tenant improvement and leasing commission expenditures related to new and renewal leasing that occur after June 30, 2010. Any increases in such expenditures would be directly related to such new and renewal leasing in that such expenditures would be incurred when a new lease is signed or an expiring lease is renewed, and are not included herein because we have no contractual obligations at this time for such future leasing.

(4)
Estimated annual provision for recurring capital expenditures is based on $      per leasable square foot of such expenditures for our consolidated portfolio. This estimate is based on the historical weighted average of our existing portfolio, on a per square foot basis, of annual recurring capital expenditures from 2007 through 2009 and the annualized six months ended June 30, 2010.

DILUTION

        Purchasers of our common stock offered in this prospectus will experience an immediate and substantial dilution of the net tangible book value of our common stock from the initial public offering price. As of June 30, 2010, we had a net tangible book value of approximately $         million, or $      per share of our common stock held by continuing investors, assuming the exchange of common units into shares of our common stock on a one-for-one basis. After giving effect to the sale of the shares of our common stock offered hereby, including the use of proceeds as described under "Use of Proceeds," and our formation transactions, the deduction of underwriting discounts and commissions, and estimated formation transaction and offering expenses, the pro forma net tangible book value as of June 30, 2010 attributable to common shareholders, including the effects of the grant of LTIP units and restricted shares of common stock to our executive officers, directors and certain employees, would have been $         million, or $        per share of our common stock. This amount represents an immediate increase in net tangible book value of $        per share to continuing investors and an immediate dilution in pro forma net tangible book value of $        per share from the assumed public offering price of $      per share of our common stock to new public investors. See "Risk Factors—Risks Related to this Offering—Differences between the book value of the assets to be acquired in our formation transactions and the price paid for our common stock will result in an immediate and material dilution of the book value of our common stock." The following table illustrates this per share dilution:

(1)
Net tangible book value per share of our common stock before our formation transactions and this offering is determined by dividing net tangible book value based on June 30, 2010 net book value of the tangible assets (consisting of total assets less intangible assets, which are comprised of goodwill (if applicable), deferred financing and leasing costs, acquired above-market leases and acquired in place lease value, net of liabilities to be assumed, excluding acquired below market leases and acquired above-market ground leases) of our predecessor by the number of shares of our common stock held by continuing investors after this offering, assuming the conversion into shares of our common stock on a one-for-one basis of the common units to be issued in connection with our formation transactions.

(2)
Increase in the net tangible book value attributable to the formation transactions, but before the offering, was determined by dividing the difference between the pro forma net tangible book value, excluding net offering proceeds, and the net tangible book value of the predecessor by the number of operating partnership units to be issued to continuing investors.

(3)
Increase in the net tangible book value attributable to the offering was determined by dividing the net offering proceeds by the number of shares of common stock (excluding LTIP units) and common units to be issued to continuing investors, assuming the exchange in full of common units on a one-for-one basis for common stock.

(4)
Based on pro forma net tangible book value of approximately $         million divided by the sum of                   shares of our common stock and common units to be outstanding after this offering, not including     shares of common stock issuable upon exercise of unvested LTIP units granted under our equity incentive plan.

(5)
Dilution is determined by subtracting pro forma net tangible book value per share of our common stock after giving effect to our formation transactions and this offering from the initial public offering price paid by a new investor for a share of our common stock.

SELECTED FINANCIAL INFORMATION

        The following table sets forth selected financial and operating data on (1) a pro forma basis for our company and (2) an historical basis for the STAG Predecessor Group. On a pro forma basis we will own 89 industrial properties consisting of 57 properties owned by STAG Predecessor Group and 32 properties that constitute STAG Contribution Group. STAG Predecessor Group, which includes the entity that is considered our accounting acquirer, is part of our predecessor business and consists of the subsidiaries of Fund III that will be contributed to us by Fund III in our formation transactions. STAG Contribution Group consists of the properties owned by Fund IV and STAG GI that will be contributed to us in the formation transactions.

        In the selected financial and operating data, we have not presented historical financial information for STAG Industrial, Inc. because we have not had any corporate activity since our formation other than the issuance of shares of common stock in connection with the initial capitalization of our company and activity in connection with our formation transactions and this offering, and because we believe that a discussion of the results of STAG Industrial, Inc. would not be meaningful.

        We have not presented historical financial information for the management company as its results are not considered significant, and because we believe that a discussion of these results, (which primarily consist of acquisition and asset management fees from Fund II, Fund III and Fund IV and general and administrative costs) would not be meaningful.

        You should read the following summary financial and operating data in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operation," our unaudited pro forma consolidated financial statements and related notes, the historical combined financial statements and related notes of STAG Predecessor Group, the historical combined statements of revenue and certain expenses and related notes of STAG Contribution Group, and the historical (combined) statements of revenue and certain expenses and related notes of the various properties listed in the Index to the Financial Statements.

        The unaudited pro forma condensed consolidated balance sheet data is presented as if this offering and our formation transactions had occurred on June 30, 2010, and the unaudited pro forma statements of operations and other data for the six months ended June 30, 2010 and the year ended December 31, 2009, is presented as if this offering and our formation transactions had occurred on January 1, 2009. The pro forma financial information is not necessarily indicative of what our actual financial condition would have been as of June 30, 2010 or what our actual results of operations would have been assuming this offering and our formation transactions had been completed as of January 1, 2009, nor does it purport to represent our future financial position or results of operations.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

        The following discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in forward-looking statements for many reasons, including the risks described in "Risk Factors" and elsewhere in this prospectus. You should read the following discussion with "Cautionary Note Regarding Forward-Looking Statements" and the combined financial statements and related notes included elsewhere in this prospectus.

        The following discussion and analysis is based on, and should be read in conjunction with, the unaudited financial statements and notes thereto as of June 30, 2010 (and for the six months ended June 30, 2010 and 2009) and the audited financial statements and notes thereto as of December 31, 2009 and 2008 (and for the years ended December 31, 2009, 2008 and 2007) of STAG Predecessor Group. We have not had any corporate activity since our formation, other than the issuance of 110 shares of our common stock in connection with our initial capitalization and activities in preparation for our formation transactions and this offering. Accordingly, we believe that a discussion of our results of operations would not be meaningful, and this discussion and analysis therefore only discusses the combined results of STAG Predecessor Group. For more information regarding these companies, see "Selected Financial Information." All significant intercompany balances and transactions have been eliminated in the financial statements.

Overview

        We are a newly formed, self-administered and self-managed full-service real estate company focused on the acquisition, ownership and management of single-tenant industrial properties throughout the United States. We will continue and grow the single-tenant industrial business conducted by our predecessor business. Mr. Butcher, the Chairman of our board of directors and our Chief Executive Officer and President, together with an affiliate of NED, a real estate development and management company, formed our predecessor business, which commenced active operations in 2004. Since inception, we have deployed more than $1.3 billion of capital, representing the acquisition of 218 properties totaling approximately 34.9 million rentable square feet in 142 individual transactions.

        Upon completion of our formation transactions and this offering, our portfolio will consist of 89 industrial properties in 26 states with approximately 13.5 million rentable square feet. Our properties consist of 42 warehouse/distribution properties, 26 manufacturing properties and 21 flex/office properties. As of June 30, 2010, our properties were 94.6% leased to 72 tenants, with no single tenant accounting for more than 5.5% of our total annualized rent and no single industry accounting for more than 14.6% of our total annualized rent.

        We intend to continue to target the acquisition of individual Class B, single-tenant industrial properties predominantly in secondary markets throughout the United States with purchase prices ranging from $5 million to $25 million. We believe that, due to observed market inefficiencies, our focus on these properties will allow us to generate returns for our shareholders that are attractive in light of the associated risks, when compared to other real estate portfolios.

        We intend to elect and qualify to be taxed as a REIT under the Code for the year ending December 31, 2010, and generally will not be subject to U.S. federal taxes on our income to the extent we currently distribute our income to our shareholders and maintain our qualification as a REIT. We are structured as an UPREIT and will own substantially all of our assets and conduct substantially all of our business through our operating partnership.

        As a result of our formation transactions, our future financial condition and results of operations will differ significantly from, and will not be comparable with, the historical financial position and

CONDITION AND RESULTS OF OPERATIONS



results of operations of STAG Predecessor Group, which will be only a part of our company after the consummation of our formation transactions. Please refer to our unaudited pro forma consolidated financial statements and related notes included elsewhere in this prospectus, which present on a pro forma basis the condition and results of our company as if our formation transactions and this offering and the application of the net proceeds thereof had all occurred on June 30, 2010 for the pro forma consolidated balance sheet and on January 1, 2009 for the pro forma consolidated statements of operations. The pro forma financial information is not necessarily indicative of what our actual financial position and results of operations would have been as of the date or for the periods indicated, nor does it propose to represent our future financial position or results of operations.

        Concurrently with this offering, we will complete our formation transactions, pursuant to which we will acquire, through a series of contribution transactions, direct or indirect interests in the management company and certain of the industrial properties owned by Fund III, Fund IV and STAG GI.

        As a result of our formation transactions, we will acquire our property portfolio together with the other assets and operations of the management company. In consideration for the contributions, we will issue an aggregate of                common units with an aggregate value of $            , assuming an offering price at the mid-point of the range set forth on the cover page of this prospectus, to the contributors of the management company, Fund III, Fund IV and STAG GI. We will also repay with the proceeds of this offering approximately $227.3 million of debt and assume approximately $166.9 million in principal amount of mortgage debt secured by our properties, based on June 30, 2010 balances.

        Our management has determined that common control does not exist among the entities constituting our predecessor business; accordingly, our formation transactions will be accounted for as a business combination. Any interests in the entities contributed by Fund III are presented in the combined financial statements of STAG Predecessor Group, which includes the entity that is considered our accounting acquirer, at historical cost. The contribution of all interests other than those directly owned by STAG Predecessor Group will be accounted for under the purchase method of accounting and recorded at the estimated fair value of acquired assets and assumed liabilities corresponding to their ownership interests. The fair values of tangible assets acquired are determined on an as-if-vacant basis. The as-if-vacant fair value will be allocated to land, building, tenant improvements and the value of in-place leases based on our own market knowledge and published market data, including current rental rates, expected downtime to lease up vacant space, tenant improvement construction costs, leasing commissions and recent sales on a per square foot basis for comparable properties in our sub-markets. The estimated fair value of acquired in-place leases are the costs we would have incurred to lease the property to the occupancy level of the property at the date of acquisition. Such estimates include the fair value of leasing commissions and legal costs that would be incurred to lease this property to this occupancy level. Additionally, we evaluate the time period over which such occupancy level would be achieved and include an estimate of the net operating costs (primarily real estate taxes, insurance and utilities) incurred during the lease-up period, which generally ranges up to eight to 15 months. Above-market and below-market in-place lease values are recorded as an asset or liability based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between the contractual amounts to be paid pursuant to the in-place leases and our estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. The fair value of the debt assumed was determined using current market interest rates for comparable debt financings.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS


        Upon consummation of our formation transactions and this offering, our operations will be carried on through our operating partnership, STAG Industrial Operating Partnership, L.P., which we formed on December 21, 2009. Our formation transactions were designed to:

        As a result, we expect to be a fully integrated, self-administered and self-managed real estate company with 23 employees providing substantial in-house expertise in asset management, property management, leasing, tenant improvement construction, acquisitions, repositioning, redevelopment, legal and financing.

Factors That May Influence Future Results of Operations

        We expect to continue our predecessor business' investment strategy of acquiring individual, Class B single-tenant industrial properties predominantly in secondary markets throughout the United States through third-party purchases and structured sale-leasebacks featuring high initial yields and strong current cash-on-cash returns. We believe that the systematic aggregation of such properties results in a diversified portfolio that will produce sustainable returns which are attractive in light of the associated risks. Future results of operations may be affected, either positively or negatively, by our ability to execute this strategy.

        We receive income primarily from rental revenue from our properties. The amount of rental revenue generated by the properties in our portfolio depends principally on our ability to maintain the occupancy rates of currently leased space and to lease currently available space and space available from lease terminations. As of June 30, 2010, properties owned by our predecessor business were approximately 94.6% leased. The amount of rental revenue generated by us also depends on our ability to maintain or increase rental rates at our properties. Future economic downturns or regional downturns affecting our submarkets that impair our ability to renew or re-lease space and the ability of our tenants to fulfill their lease commitments, as in the case of tenant bankruptcies, could adversely affect our ability to maintain or increase rental rates at our properties. Negative trends in one or more of these factors could adversely affect our rental revenue in future periods.

        Our ability to re-lease space subject to expiring leases will impact our results of operations and is affected by economic and competitive conditions in our markets and by the desirability of our individual properties. As of June 30, 2010, in addition to approximately 733,736 rentable square feet of

63


Table of Contents

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS


currently available space in our properties, leases representing approximately 4.2% and 7.8% of the rentable square footage of such portfolio are scheduled to expire prior to December 31, 2010 and December 31, 2011, respectively. The leases scheduled to expire prior to December 31, 2010 and December 31, 2011 represent approximately 4.4% and 9.9%, respectively, of the total annualized rent for our portfolio.

        The properties in our portfolio are located in markets throughout the United States. Positive or negative changes in economic or other conditions, adverse weather conditions and natural disasters in these markets may affect our overall performance.

        Our rental expenses generally consist of utilities, real estate taxes, management fees, insurance and site repair and maintenance costs. For the majority of our tenants, our rental expenses are controlled, in part, by the triple net provisions in tenant leases. In our triple net leases, the tenant is responsible for all aspects of and costs related to the property and its operation during the lease term, including utilities, taxes, insurance and maintenance costs. However, we also have modified gross leases and gross leases in our property portofolio. The terms of those leases vary and on some occasions we may absorb property related expenses of our tenants. In our modified gross leases, we are responsible for some property related expenses during the lease term, but the cost of most of the expenses is passed through to the tenant for reimbursement to us. In our gross leases, we are responsible for all aspects of and costs related to the property and its operation during the lease term. Our overall performance will be impacted by the extent to which we are able to pass-through rental expenses to our tenants.

        Following this offering, we also will incur increased general and administrative expenses, including legal, accounting and other expenses related to corporate governance, public reporting and compliance with various provisions of the Sarbanes-Oxley Act of 2002. We anticipate that our staffing levels will increase from 23 employees to between 25 and 30 employees during the next 12 to 24 months and, as a result, our general and administrative expenses will further increase.

Critical Accounting Policies

        Our discussion and analysis of the historical financial condition and results of operations of the STAG Predecessor Group are based upon its combined financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements in conformity with GAAP requires management to make estimates and assumptions in certain circumstances that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amount of revenue and expenses in the reporting period. Actual amounts may differ from these estimates and assumptions. We have provided a summary of significant accounting policies in note 2 to the combined financial statements of the STAG Predecessor Group included elsewhere in this prospectus. We have summarized below those accounting policies that require material subjective or complex judgments and that have the most significant impact on financial condition and results of operations. Management evaluates these estimates on an ongoing basis, based upon information currently available and on various assumptions that it believes are reasonable as of the date hereof. In addition, other companies in similar businesses may use different estimation policies and

64


Table of Contents

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS



methodologies, which may impact the comparability of our or the STAG Predecessor Group's results of operations and financial condition to those of other companies.

        The following discussion of critical accounting policies uses "we" and "STAG Predecessor Group" interchangeably. Except where specifically stated to the contrary, we expect the critical accounting policies of STAG Industrial, Inc. to be substantially similar to those of the STAG Predecessor Group.

        Rental property is carried at cost. We review our properties on a periodic basis for impairment and provide a provision if impairments are identified. To determine if an impairment may exist, we review our properties and identify those that have had either an event of change or event of circumstances warranting further assessment of recoverability (such as a decrease in occupancy). If further assessment of recoverability is needed, we estimate the future net cash flows expected to result from the use of the property and its eventual disposition, on an individual property basis. If the sum of the expected future net cash flows (undiscounted and without interest charges) is less than the carrying amount of the property on an individual property basis, we will recognize an impairment loss based upon the estimated fair value of such property as compared to its current carrying value.

        Depreciation expense is computed using the straight-line method based on the following useful lives:

Buildings   40 years
Building and land improvements   5 - 21 years
Tenant improvements   Shorter of useful life or terms of related lease

        Expenditures for tenant improvements, leasehold improvements and leasing commissions are capitalized and amortized or depreciated over the shorter of their useful lives or the terms of each specific lease. Repairs and maintenance are charged to expense when incurred. Expenditures for improvements are capitalized.

        We account for all acquisitions in accordance with the guidance issued by the Financial Accounting Standards Board ("FASB") under FASB Accounting Standard Codification ("ASC"), ASC 805, Business Combinations, (formerly known as Statement of Financial Accounting Standards ("SFAS") No. 141(R)). The FASB issued ASC 805 to improve the relevance, representational faithfulness, and comparability of the information that a reporting entity provides in its financial reports about a business combination and its effects. The statement is to be applied prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. We adopted ASC 805 on January 1, 2009 and the adoption did not have a material effect on the combined financial statements.

        Upon acquisition of a property, we allocate the purchase price of the property based upon the fair value of the assets acquired, which generally consist of land, buildings, tenant improvements and intangible assets including in-place leases, above market and below market leases and tenant relationships. We allocate the purchase price to the fair value of the tangible assets of an acquired property by valuing the property as if it were vacant. Acquired above and below market leases are valued based on the present value of the difference between prevailing market rates and the in-place rates measured over a period equal to the remaining term of the lease for above market leases and the initial term plus the term of any below market fixed rate renewal options for below market leases that are considered bargain renewal options. The above market lease values are amortized as a reduction of

65


Table of Contents

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS



rental income over the remaining term of the respective leases, and the below market lease values are amortized as an increase to base rental income over the remaining initial terms plus the terms of any below market fixed rate renewal options that are considered bargain renewal options of the respective leases.

        We maintain an allowance for estimated losses that may result from the inability of tenants to make required payments. We regularly assess our ability to collect outstanding payments and in so doing must make estimates of the collectability of tenant accounts receivable. If a tenant fails to make contractual payments beyond any allowance, we may recognize bad debt expense in future periods equal to the amount of unpaid rent and deferred rent.

        Financial instruments include cash and cash equivalents, tenant accounts receivable, interest rate swaps, accounts payable, other accrued expenses and mortgage notes payable. The fair values of the cash and cash equivalents, tenant accounts receivable, accounts payable and other accrued expenses approximate their carrying or contract values.

        We calculate the fair value of mortgage notes payable by discounting the future cash flows using the current rates at which loans would be made to borrowers with similar credit ratings for loans with similar remaining maturities and similar loan-to-value ratios.

        We account for interest rate swaps in accordance with ASC 815, Derivatives and Hedging, (formerly known as SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended by SFAS No. 138, Accounting for Certain Derivative Instruments and Certain Hedging Activities). On January 1, 2009, we adopted SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities, an Amendment of FASB Statement No. 133 (SFAS 161), which changes the disclosure requirements for derivative instruments and hedging activities. The adoption of SFAS 161 (now included in ASC 815) did not have a material impact on our results of operations or financial condition.

        We designate interest rate swaps as non-hedge instruments. Accordingly, we recognize the fair value of the interest rate swap as asset or liability on the combined balance sheets with the changes in fair value recognized in the combined statements of operations.

        We adopted the fair value measurement provisions as of January 1, 2008 for our interest rate swaps recorded at fair value. The new guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. As of December 31, 2009 and 2008, we applied the provisions of this standard to the valuation of our interest rate swaps, which are the only financial instruments measured at fair value on a recurring basis.

CONDITION AND RESULTS OF OPERATIONS


        Rental revenue is recognized on a straight-line basis over the term of the lease when collectability is reasonably assured. Differences between rental revenue earned and amounts due under the lease are charged or credited, as applicable, to accrued rental revenue. Additional rents from expense reimbursements for insurance, real estate taxes and certain other expenses are recognized in the period in which the related expenses are incurred.

        Certain tenants are obligated to make payments for insurance, real estate taxes and certain other expenses and these costs, which have been assumed by the tenants under the terms of their respective leases, are not reflected in our combined financial statements. To the extent any tenant responsible for these costs under their respective lease defaults on their lease or it is deemed probable that they will fail to pay for such costs, we would record a liability for such obligation.

        Rental revenue from month-to-month leases or leases with no scheduled rent increases or other adjustments is recognized on a monthly basis when earned.

        Lease termination fees are recognized as termination revenue when the related leases are canceled and we have no continuing obligation to provide services to such former tenants. STAG Predecessor Group has no lease termination revenue for the years presented.

        We recognize gains on sales of real estate pursuant to the provisions of ASC 360-20-15, Accounting for Sales of Real Estate (formerly known as SFAS No. 66). The specific timing of a sale is measured against various criteria in ASC 360-20-15 related to the terms of the transaction and any continuing involvement in the form of management or financial assistance associated with the property. If the sales criteria are not met, we defer gain recognition and accounts for the continued operations of the property by applying the finance, installment or cost recovery methods, as appropriate, until the sales criteria are met.

Historical Results of Operations of STAG Predecessor Group

        The following table summarizes our historical results of operations for the six months ended June 30, 2010 and 2009 (unaudited) and the years ended December 31, 2009, 2008, and 2007.

        Certain properties included in the STAG Predecessor Group were owned by a related party for the period August 11, 2006 through May 31, 2007, its commencement date of operations. The period for which certain properties were owned by a related party is labeled Antecedent. The two periods of ownership have been separated by a vertical line on the face of the combined statements of operations to highlight the fact that the financial information for such periods has been prepared under two different historical-cost bases of accounting. We have prepared our discussion of the results of operations for the year ended December 31, 2007 by comparing the results of operations of STAG Predecessor Group for the years ended December 31, 2008 to the combined amounts for 2007 obtained by adding the audited operating results of each of the Antecedent for the period of January 1, 2007 to May 31, 2007 and STAG Predecessor Group period of June 1, 2007 to December 31, 2007 (since the difference in basis between Antecedent and STAG Predecessor Group were not materially different and the entities were under common management). Although this combined presentation does not comply with GAAP, we believe that it provides a meaningful method of comparison.

Tenant recoveries related to reimbursement of real estate taxes, insurance, repairs and maintenance, and other operating expenses are recognized as revenue in the period the applicable expenses are incurred.

        Total revenue decreased by $360,000, or 2.3%, to $15.0 million for the six months ended June 30, 2010 compared to $15.4 million for the six months ended June 30, 2009. A detailed analysis of the increase follows.

        Rent.    Rental revenue decreased by $452,000, or 3.4%, to $12.6 million for the six months ended June 30, 2010 compared to $13.0 million for the six months ended June 30, 2009. The decrease was primarily attributable to lower occupancy levels and lower rental rates primarily on new leases during the six months ended June 30, 2010.

        Tenant recoveries.    Tenant recoveries increased by $92,000, or 3.9%, to $2.5 million for the six months ended June 30, 2010, compared to $2.4 million for the six months ended June 30, 2009. The increase in tenant recoveries was primarily attributable to the amount of tenant specific billings related to real estate tax and insurance recoveries compared to the previous period. The increase was partially offset by a decrease in tenant recoveries attributable to lower occupancy rates.

        Property.    Property expense, which consists of property operation and maintenance expenses and bad debt expense decreased by $912,000, or 34.3%, to $1.7 million for the six months ended June 30, 2010 compared to $2.7 million for the six months ended June 30, 2009. The decrease was primarily attributable to $1.1 million in bad debt expense incurred during the six months ended June 30, 2009. The bad debt expense resulted from non-payment of rent and reimbursable expenses from four financially troubled tenants. These decreases were partially offset by an increase in carrying costs related to lower occupancy rates during the six months ended June 30, 2010.

        General and administrative.    General and administrative expenses increased $53,000, or 29.8%, to $231,000 for the six months ended June 30, 2010 from $178,000 for the six months ended June 30, 2009. The increase was primarily attributable to additional legal and accounting fees incurred.

        Real estate taxes and insurance.    Real estate taxes and insurance increased by $45,000, or 3.0%, to $1.6 million for the six months ended June 30, 2010 compared to $1.5 million for the six months ended June 30, 2009. The increase was primarily attributable to higher real estate tax assessments at various properties, offset by lower insurance fees incurred.

        Asset management fees.    Asset management fees remained unchanged at $297,000 for the six months ended June 30, 2010 and 2009, respectively.

        Depreciation and amortization.    Depreciation and amortization expense decreased $266,000, or 4.8%, to $5.3 million for the six months ended June 30, 2010 compared to $5.6 million for the six months ended June 30, 2009. The decrease was primarily attributable to accelerated amortization of lease intangibles recorded during the six months ended June 30, 2009 in connection with certain lease terminations.

        Interest income.    Interest income decreased 66.7% to $2,000 for the six months ended June 30, 2010 from $6,000 for the six months ended June 30, 2009. The decrease was primarily attributable to declining interest rates on bank deposit accounts and lower cash balances.

        Interest expense.    Interest expense increased $131,000, or 1.9%, to $6.9 million for the six months ended June 30, 2010 compared to $6.8 million for the six months ended June 30, 2009. The increase was attributable to a new loan amendment entered into in 2009 with higher interest rate spreads. The increase was partially offset by a reduction in loan balances due to amortized principal payments under amended loan agreements.

        Gain (loss) on interest rate swaps.    Our loss on interest rate swaps was $935,000 for the six months ended June 30, 2010 compared to a gain of $800,000 for the six months ended June 30, 2009. The decrease was primarily attributable to larger underlying notional amounts under the swap agreements and a decrease in the forward rate of the underlying LIBOR-based floating rate debt.

        Total revenue decreased by $1.1 million, or 3.5%, to $30.2 million for the year ended December 31, 2009 compared to $31.3 million for the year ended December 31, 2008. A detailed analysis of the decrease follows.

        Rent.    Rent decreased by $1.7 million, or 6.1%, to $25.7 million for the year ended December 31, 2009 compared to $27.3 million for the year ended December 31, 2008. The two primary components of the decrease were lower occupancy levels and the write-off of above market lease intangible assets. Rental revenue decreased $923,000 due to lower occupancy during 2009. Rental revenue decreased $690,000 due to the write-off of above market lease intangible assets related to a lease termination.

        Tenant recoveries.    Tenant recoveries increased by $600,000, or 14.1%, to $4.5 million for the year ended December 31, 2009 compared to $4.0 million for the year ended December 31, 2008. The increase in tenant recoveries was primarily attributable to the amount of tenant specific billings related to real estate tax and insurance recoveries compared to the previous period. The increase was partially offset by a decrease in tenant recoveries attributable to lower occupancy rates.

        Property.    Property expense, which consists of property operation and maintenance expenses and bad debt expense, increased by $2.3 million, or 77.5%, to $5.3 million for the year ended December 31, 2009 compared to $3.0 million for the year ended December 31, 2008. The increase was primarily attributable to an increase of $1.9 million in bad debt expense recorded in 2009. The increase in bad debt expense resulted from nonpayment of rent and reimbursable expenses from five financially troubled tenants. The increase in property expense was also attributable to approximately $250,000 of environmental remediation costs incurred in connection with our Daytona Beach, FL property.

        General and administrative.    General and administrative expenses decreased $24,327, or 4.8%, to $478,141 for the year ended December 31, 2009 from $502,468 for the year ended December 31, 2008. The decrease was primarily attributable to a reduction in legal fees incurred and a reduction in appraisal fees, partially offset by an increase in accounting fees.

        Real estate taxes and insurance.    Real estate taxes and insurance increased by $263,088, or 9.4%, to $3.1 million for the year ended December 31, 2009 compared to $2.8 million for the year ended December 31, 2008. The increase was primarily attributable to a payment made for real estate taxes on our St. Louis, MO property on behalf of a non-paying tenant. This increase was partially offset by lower real estate tax assessments at various other properties.

        Asset management fees.    Asset management fees decreased $9,883, or 1.6%, to $599,869 for the year ended December 31, 2009 from $609,752 for the year ended December 31, 2008.

        Depreciation and amortization.    Depreciation and amortization expense decreased $1.9 million, or 15.3%, to $10.3 million for the year ended December 31, 2009 compared to $12.1 million for the year ended December 31, 2008. The decrease was primarily attributable to accelerated amortization of lease intangibles related to lease terminations during the year ended December 31, 2008. The decrease was also attributable to a reduced asset base for depreciation purposes due to a 2008 asset impairment.

        Loss on impairment.    There were no impairment charges for the year ended December 31, 2009 compared to $3.7 million for the year ended December 31, 2008. The 2008 impairment charge was attributable to the impairment of our property located in Daytona Beach, Florida. The loss of occupancy, its continued vacancy and lower market rents indicated that the carrying amount of this property had been impaired.

        Interest income.    Interest income decreased $73,632, or 52.4%, to $66,852 for the year ended December 31, 2009 from $140,484 for the year ended December 31, 2008. The decrease was primarily attributable to declining bank deposit balances resulting from an increase in principal payments on debt during the year ended December 31, 2009.

        Interest expense.    Interest expense decreased $729,490, or 4.8%, to $14.3 million for the year ended December 31, 2009 compared to $15.1 million for the year ended December 31, 2008. The decrease was primarily attributable to a reduction in interest rates and loan balances due to amortized principal payments under amended loan agreements.

        Gain (loss) on interest rate swaps.    Our loss on interest rate swaps increased $445,720, or 35.0%, to $1.7 million for the year ended December 31, 2009 compared to $1.3 million for the year ended December 31, 2008. The increase was primarily attributable to larger underlying notional amounts under the swap agreements and an increase in the interest rate swap spread.

        Total revenue increased by $18.8 million, or 150.4%, to $31.3 million for the year ended December 31, 2008 compared to $12.5 million for the year ended December 31, 2007. A detailed analysis of the increase follows.

        Rent.    Rent increased by $16.2 million, or 144.7%, to $27.3 million for the year ended December 31, 2008 compared to $11.2 million for the year ended December 31, 2007. The increase was primarily attributable to the full-year recognition of rental income generated from properties that were acquired during 2007.

        Tenant recoveries.    Tenant recoveries increased by $2.6 million, or 198.1%, to $4.0 million for the year ended December 31, 2008 compared to $1.3 million for the year ended December 31, 2007. The increase was primarily attributable to the full-year recognition of tenant recovery revenue generated from properties that were acquired during 2007.

        Property.    Property expense increased by $2.5 million, or 445.0%, to $3.0 million for the year ended December 31, 2008 compared to $551,593 for the year ended December 31, 2007. The increase was primarily attributable to recognition of a full year of expenses from the properties that were acquired during 2007.

        General and administrative.    Our general and administrative expenses increased $98,829, or 24.5%, to $502,468 for the year ended December 31, 2008 from $403,639 for the year ended December 31,

2007. The increase was primarily attributable to additional legal and accounting fees incurred, partially offset by a decrease in management company reimbursements.

        Real estate taxes and insurance.    Real estate taxes and insurance increased by $1.9 million, or 217.0%, to $2.8 million for the year ended December 31, 2008 compared to $884,612 for the year ended December 31, 2007. The increase was primarily attributable to recognition of a full year of real estate taxes and insurance expenses for the properties that were acquired during 2007.

        Asset management fees.    Asset management fees increased $364,952, or 149.1%, to $609,752 for the year ended December 31, 2008 from $244,800 for the year ended December 31, 2007. The increase was attributable to the full-year recognition of asset management fees relating to properties acquired during 2007.

        Depreciation and amortization.    Depreciation and amortization expense increased $7.4 million, or 158.3%, to $12.1 million for the year ended December 31, 2008 compared to $4.7 million for the year ended December 31, 2007. The increase was primarily attributable to the full-year recognition of depreciation and amortization expense relating to properties acquired during 2007 and to accelerated amortization in 2008 of lease intangibles related to lease terminations during the year. The increase was partially offset by a reduced asset base for depreciation purposes due to a 2008 asset impairment.

        Loss on impairment.    Our impairment charges were $3.7 million for the year ended December 31, 2008 compared to no impairment charges for the year ended December 31, 2007. The 2008 impairment charge was attributable to the impairment of our property located in Daytona Beach, Florida. The loss of occupancy, its continued vacancy and reduced market rents indicated that the carrying amount of this property had been impaired.

        Interest income.    Interest income decreased $23,016, or 14.1%, to $140,484 for the year ended December 31, 2008 from $163,500 for the year ended December 31, 2007. The decrease was primarily attributable to declining interest rates on bank deposit accounts.

        Interest expense.    Interest expense increased $7.2 million, or 91.5%, to $15.1 million for the year ended December 31, 2008 compared to $7.9 million for the year ended December 31, 2007. The increase was attributable to the full-year recognition of interest expense relating to properties acquired during the year ended December 31, 2007. The increase was partially offset by a decrease in interest expense on our properties on a same store basis as a result of decreased interest rates under our LIBOR-based floating rate loans during 2008.

        Gain (loss) on interest rate swaps.    Our loss on interest rate swaps was $1.3 million for the year ended December 31, 2008 compared to no loss for the year ended December 31, 2007. We swapped $87.6 million of floating rate debt for fixed rate debt during the year ended December 31, 2008. The loss was primarily attributable to a decrease in the forward rate of the underlying LIBOR-based floating rate debt. We were not party to any such agreements during the year ended December 31, 2007.

Liquidity and Capital Resources

        Our short-term liquidity requirements consist primarily of funds to pay for operating expenses and other expenditures directly associated with our properties, including:

In addition, we will require funds for future dividends expected to be paid to our common shareholders and unit holders in our operating partnership.

        We intend to satisfy our short-term liquidity requirements through our existing cash and cash equivalents, cash flow from operating activities, the proceeds of this offering and borrowings available under a credit facility.

        Our long-term liquidity needs consist primarily of funds necessary to pay for acquisitions, non-recurring capital expenditures and scheduled debt maturities. We intend to satisfy our long-term liquidity needs through cash flow from operations, long-term secured and unsecured borrowings, issuance of equity securities, or, in connection with acquisitions of additional properties, the issuance of common units of the operating partnership property dispositions and joint venture transactions.

        Following completion of this offering, our debt will be comprised of a $73.0 million loan maturing in 2012, an $85.4 million loan maturing in 2018 and an $8.5 million loan maturing in 2027. We are currently negotiating with several financial institutions regarding the establishment of a $             million corporate credit facility (subject to increase to $             million under certain circumstances) that we expect will close contemporaneously with the closing of this offering. This facility will be used for property acquisitions, working capital requirements and other general corporate purposes. We anticipate that the proposed credit facility will contain customary terms, covenants and other conditions for credit facilities of this type. In addition, we are currently negotiating the extension of the maturity date of the Anglo Master Loan (Fund III), which matures in 2012. No assurances can be given that we will obtain any credit facility or extension or if we do what the terms will be.

        Certain of our loan agreements contain financial covenants. Our Anglo Master Loan Fund III described above contains a loan-to-value requirement with respect to the collateral properties that is measured annually and a minimum debt service coverage ratio that is measured semi-annually. Our loan with RBS Citizens and Bank of America contains a loan-to-value requirement with respect to the collateral properties that is measured annually and a minimum debt service coverage ratio that is measured quarterly. We are currently in compliance with the financial covenants in our loan agreements.

        We are currently negotiating with several financial institutions regarding the establishment of a $             million (subject to increase to $             million under certain circumstances) that we expect will close contemporaneously with the closing of this offering. This facility will be used for property acquisitions, working capital requirements and other general corporate purposes. We anticipate that the proposed credit facility will contain customary terms, covenants and other conditions for credit facilities of this type. In addition, we are currently negotiating the extension of the maturity date of the Anglo Master Loan (Fund III), which matures in 2012. No assurances can be given that we will obtain any credit facility or extension or if we do what the terms will be.

Off Balance Sheet Arrangements

        As of June 30, 2010, neither STAG Predecessor Group nor, on a pro forma basis, our company, had any off-balance sheet arrangements.

Interest Rate Risk

        ASC 815, Derivatives and Hedging (formerly known as SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended by SFAS No. 138, Accounting for Certain Derivative Instruments and Certain Hedging Activities), requires us to recognize all derivatives on the balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value and the changes in fair value must be reflected as income or expense. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of derivatives are either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings or recognized in other comprehensive income, which is a component of shareholders equity. The ineffective portion of a derivative's change in fair value is immediately recognized in earnings. Because our predecessor business did not previously prepare financial statements in accordance with GAAP, we did not designate the hedges at the time of inception and therefore, our existing investment in interest rate swaps does not qualify as an effective hedge, and as such, changes in the swaps' fair market value are being recorded in earnings.

        As of June 30, 2010, on a pro forma basis, we had approximately $73.0 million of mortgage debt subject to interest rate swaps with such interest rate swaps having an approximate $1.8 million net fair value. As these interest rate swaps were entered into prior to us reporting on a GAAP basis, they are designated as non-hedge instruments.

We have prepared the results of operations for the year ended December 31, 2007 by combining amounts for 2007 obtained by adding the audited operating results of each of the Antecedent for the period of January 1, 2007 to May 31, 2007 and STAG Predecessor Group for the period of June 1, 2007 to December 31, 2007 (since the difference in basis between Antecedent and STAG Predecessor Group were not materially different and the entities were under common management). Although this combined presentation does not comply with GAAP, we believe that it provides a meaningful method of comparison.

        Net cash provided by operating activities.    Net cash provided by operating activities decreased $0.1 million to $4.7 million for the six months ended June 30, 2010 compared to $4.8 million for the six months ended June 30, 2009. The decrease in cash provided by operating activities was primarily attributable to the net changes in current assets and liabilities.

        Net cash used in investing activities.    Net cash used in investing activities decreased $0.3 million to $(1.1) million for the six months ended June 30, 2010 compared to $(1.4) million for the six months ended June 30, 2009. The change is attributable to a decrease in building improvements made during the six months ended June 30, 2010.

        Net cash used in financing activities.    Net cash used in financing activities increased $1.1 million to $4.0 million for the six months ended June 30, 2010 compared to $2.9 million for the six months ended June 30, 2009. The increase was primarily attributable to an increase in distributions and an increase in principal payments on mortgage loans, partially offset by a decrease in deferred financing fees.

        Net cash provided by operating activities.    Net cash provided by operating activities decreased $66,000 to $8.4 million for the year ended December 31, 2009 compared to $8.4 million for the year ended December 31, 2008. The decrease in 2009 cash provided by operating activities was primarily attributable to net changes in current assets and liabilities.

        Net cash used in investing activities.    Net cash used in investing activities increased $1.6 million to $(2.0) million for the year ended December 31, 2009 compared to $(0.4) million for the year ended December 31, 2008. The change is attributable to an increase in building improvements made during 2008.

        Net cash used in financing activities.    Net cash used in financing activities decreased $1.6 million to $(6.9) million for the year ended December 31, 2009 compared to $(8.5) million for the year ended December 31, 2008. The decrease in cash used in financing activities was primarily attributable to a decrease in distributions of $4.8 million and an increase in proceeds from other notes payable of $4.4 million. The decrease was offset by an increase in deferred financing costs of $0.4 million and an increase in principal payments on mortgage loans of $7.2 million.

        Net cash provided by operating activities.    Net cash provided by operating activities increased $4.9 million to $8.4 million for the year ended December 31, 2008 compared to $3.5 million for the year ended December 31, 2007. The increase was primarily due to the full-year recognition of operating activities in 2008 relating to properties acquired during the year ended December 31, 2007. The increase is also attributable to net changes in current assets and liabilities.

        Net cash used in investing activities.    Net cash used in investing activities decreased $203.3 million to $0.4 million for the year ended December 31, 2008 compared to $(203.7) million for the year ended December 31, 2007. The change is attributable to a decrease in cash used for property acquisitions and deferred costs resulting from the completion of the acquisition phase of our real estate investment program during 2007.

        Net cash provided by (used in) financing activities.    Net cash provided by (used in) financing activities decreased $213.1 million to $(8.5) million for the year ended December 31, 2008 compared to $204.6 million for the year ended December 31, 2007. The change is primarily attributable to a decrease in proceeds from mortgage loans and a decrease in investor contributions resulting from the completion of the acquisition phase of our real estate investment program during 2007. An increase in distributions also contributed to the decrease.

Non-GAAP Financial Measures

        In this prospectus, we disclose and discuss NOI, EBITDA, FFO and AFFO, all of which meet the definition of "non-GAAP financial measure" set forth in Item 10(e) of Regulation S-K promulgated by the SEC.  As a result we are required to include in this prospectus a statement of why management believes that presentation of these measures provides useful information to investors.

        None of NOI, EBITDA, FFO or AFFO should be considered as an alternative to net income (determined in accordance with GAAP) as an indication of our performance, and we believe that to understand our performance further, NOI, EBITDA, FFO and AFFO should be compared with our reported net income or net loss and considered in addition to cash flows in accordance with GAAP, as presented in our consolidated financial statements.

Net Operating Income (NOI)

        We consider NOI to be an appropriate supplemental measure to net income because it helps both investors and management to understand the core operations of our properties. We define NOI as operating revenue (including rental revenue, tenant recoveries and other operating revenue) less property-level operating expenses (which includes management fees and general and administrative

expenses). NOI excludes depreciation and amortization, impairments, gain/loss on sale of real estate, interest expense and other non-operating items.

Funds from Operations (FFO)

        We calculate FFO before non-controlling interest in accordance with the standards established by the National Association of Real Estate Investment Trusts ("NAREIT"). FFO represents net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of depreciable operating property, real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures.

        Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs.

        However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effects and could materially impact our results from operations, the utility of FFO as a measure of our performance is limited. Other equity REITs may not calculate FFO in accordance with the NAREIT definition as we do, and, accordingly, our FFO may not be comparable to such other REITs' FFO. FFO should not be used as a measure of our liquidity, and is not indicative of funds available for our cash needs, including our ability to pay dividends.

        As with FFO, our reported AFFO may not be comparable to other REITs' AFFO, should not be used as a measure of our liquidity, and is not indicative of our funds available for our cash needs, including our ability to pay dividends.

        The majority of our leases are either triple net or provide for tenant reimbursement for costs related to real estate taxes and operating expenses In addition, most of the leases provide for fixed rent increases. We believe that inflationary increases may be at least partially offset by the contractual rent increases and tenant payment of taxes and expenses described above. We do not believe that inflation has had a material impact on our historical financial position or results of operations.

Newly Issued Accounting Standards

        In June 2009, the FASB issued an accounting standard that requires enterprises to perform a more qualitative approach to determining whether or not a variable interest entity will need to be consolidated. This evaluation will be based on an enterprise's ability to direct and influence the activities of a variable interest entity that most significantly impact its economic performance. It requires ongoing reassessments of whether an enterprise is the primary beneficiary of a variable interest entity. This accounting standard is effective for fiscal years beginning after November 15, 2009. We adopted this guidance and the adoption of this guidance did not have a material impact on our combined financial statements.

        In August 2009, the FASB issued guidance on Fair Value Measurements and Disclosures—Measuring Liabilities at Fair Value. The objective of the new guidance is to provide clarification for the fair value measurement of liabilities, specifically providing clarification that in circumstances in which a quoted price in an active market for an identical liability is not available, a reporting entity is required to measure fair value using certain prescribed techniques. Techniques highlighted include using the quoted price of the identical liability when traded as an asset, quoted prices for similar liabilities or similar liabilities when traded as assets, or another valuation technique that is consistent with the principles of fair value measurements. The new guidance also clarifies that when estimating the fair value of a liability, a reporting entity is not required to include a separate input or adjustment to other inputs relating to the existence of a restriction that prevents the transfer of the liability. Finally, the guidance clarifies that both a quoted price in an active market for the identical liability and the quoted price for the identical liability when traded as an asset in an active market when no adjustment to the quoted price of the asset are required are Level 1 fair value measurements. We adopted this guidance and the adoption of this guidance did not have a material impact on our combined financial statements.

Quantitative and Qualitative Disclosure About Market Risk

        Our future income, cash flows and fair values relevant to financial instruments are dependent upon prevailing market interest rates. Market risk refers to the risk of loss from adverse changes in market prices and interest rates. We use derivative financial instruments to manage, or hedge, interest rate risks related to our borrowings, primarily through interest rate swaps.

        An interest rate swap is a contractual agreement entered into by two counterparties under which each agrees to make periodic payments to the other for an agreed period of time based on a notional amount of principal. Under the most common form of interest rate swap, known from our perspective as a floating-to-fixed interest rate swap, a series of floating, or variable, rate payments on a notional amount of principal is exchanged for a series of fixed interest rate payments on such notional amount.

        As of June 30, 2010, our predecessor business had hedged a portion of its variable rate mortgage debt through floating-to-fixed interest rate swaps in the aggregate notional amount of approximately $73.0 million whereby, as described above, it swapped the variable rate interest on the hedged debt for a fixed rate of interest. The market values of the swaps depend heavily on the current market fixed rate, the corresponding term structures of variable rates and the expectation of changes in future variable rates. As expectations of future variable rates change, the market values of the swaps change. We will treat the swaps as non-hedge instruments and, accordingly, recognize the fair value of the swaps as assets or liabilities on our balance sheet, with the change in fair value recognized in our statements of operations.

        No assurance can be given that our predecessor business's hedging activities, or any future hedging activities by us, will have the desired beneficial effect on our results of operations or financial condition.

        Interest risk amounts are our management's estimates and were determined by considering the effect of hypothetical interest rates on our financial instruments. These analyses do not consider the effect of any change in overall economic activity that could occur in that environment. Further, in the event of a change of that magnitude, we may take actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, these analyses assume no changes in our financial structure.

        As of June 30, 2010, we had total pro forma outstanding debt of approximately $166.9 million, and we expect that we will incur additional indebtedness in the future. Interest we pay reduces our cash available for distributions. Approximately $73.0 million of our pro forma outstanding debt as of June 30, 2010 bears interest at a variable rate, but this entire variable debt amount has been swapped to fixed rate debt.

MARKET OVERVIEW

        Unless otherwise indicated, all information contained in this Market Overview section is derived from market materials prepared by CBRE-EA as of September 14, 2010, and the projections and beliefs of CBRE-EA stated herein are as of that date.

Market Opportunity

        The single-tenant industrial sector offers investors the opportunity to receive stable income from leases to a variety of firms across a broad spectrum of industrial sub-property types. As compared to multi-tenant and other classes of commercial property, single-tenant industrial buildings are more likely to provide their owners with less volatile cash flows after expenses, as single-tenant industrial buildings generally do not require the same degree of tenant and capital improvement expenditures on an ongoing basis.

        In recent years, the single-tenant industrial market has attracted a diverse set of buyers and sellers, from private funds, REITs and individual investors, similar to the multi-tenant industrial market. Despite a low level of investment sales recorded in 2009 and early 2010, over the past decade, single-tenant properties have consistently accounted for close to 20% of the total industrial investment sales volume tracked by Real Capital Analytics. As liquidity is gradually restored to the broader commercial real estate market, opportunities for conventional sale and sale-leaseback opportunities from owner-users are likely to increase.

        Due to the recent capital market dislocation on commercial real estate values, the single-tenant industrial market currently offers a favorable investment opportunity, as recent transactions indicate average sales prices have declined and capitalization rates have increased in recent quarters compared with prior years, according to Real Capital Analytics. Capitalization rates represent the ratio of a property's annual net operating income to its purchase price. Recent sales transactions indicate that opportunities exist to acquire select single-tenant industrial assets at a favorable cost basis compared with pre-distortion periods.

        Within the context of the broader real estate market, industrial property has exhibited a number of favorable investment characteristics. Based on the National Council of Real Estate Investment Fiduciaries ("NCREIF") Property Index, industrial property has generally outperformed commercial property as a whole on a total return basis over the long term by generating high and stable cash-flow yields. Furthermore, Class B industrial space and secondary markets offer a higher degree of stability in occupancies and rents, relative to Class A space and primary markets. At the same time, Class B property prices are regularly discounted significantly compared to Class A property prices, providing a compelling investment opportunity for Class B property.

        While current industrial market occupancy and rent conditions remain challenging, statistics compiled by CBRE-EA indicate market rents and occupancies are likely to improve in 2011.

Size of the Industrial Sector

        As of June 30, 2010, the overall U.S. industrial market consisted of approximately 269,000 buildings with more than 14 billion square feet of space. In terms of net rentable area ("NRA"), warehouse/distribution facilities constituted the majority (60.1%) of this space, followed by manufacturing (25.1%), and flex/office (which includes research and development) (11.8%).
