Multiple Shipments of Hemp-Derived Nanoemulsified CBD Planned for Q4 2022 to Fill Existing Orders for Bulk Material Destined for White Label Use; Company Expects Q4 2022 Incremental Revenue in the Hundreds of Thousands of Dollars and in the Millions of Dollars for FY 2023

SOUTH EASTON, MA / ACCESSWIRE / September 28, 2022 / Pressure BioSciences, Inc. (OTCQB:PBIO) ("PBI" and the "Company"), a leader in the development and sale of innovative, broadly enabling, pressure-based instruments, consumables, and specialty testing services to the worldwide food and beverage, health and wellness, nutraceuticals, cosmetics, pharmaceuticals, and other key industries, today announced the Company's participation in the September 28^th Emerging Growth Investor Conference. This real-time, interactive conference will feature a number of exciting, rapidly-growing publicly traded companies, presenting for 30-45 minutes each. PBI's President and CEO, Mr. Richard T. Schumacher, is scheduled to be the first presenter of the conference, speaking at 9:00 am ET. Mr. Schumacher will focus the majority of his talk on the much-anticipated commercial launch of the Company's powerful, patented, and unique Ultra Shear Technology™ (UST™) nanoemulsification platform.

Over the past few months, PBI has announced the execution of three agreements covering the production, distribution, commercial roll-out, and financial partnership for novel, effectively water-soluble, highly bioavailable, nanoemulsified CBD products for both oral and topical use. Recently, the Company also announced the execution of a cosmeceuticals partnership with Dr. Denese SkinScience, a 20-year skincare industry leader with over $500 million in QVC sales.

All four contracts are based on the use of the UST platform to develop nanoemulsions of oil-based nutraceuticals and cosmetics. Nanoemulsions are known to turn oil-based active ingredient mixtures (e.g., CBD, THC, Astaxanthin, Curcumin, Retinol, Prednisone) into long-term stable, effectively water-soluble, highly bioavailable formulations. The Company believes these four contracts alone could generate over $5 million of accretive revenue for PBI in 2023. The Company plans to close on a minimum of six additional contracts over the remaining months of FY 2022, further adding to 2023 revenue.

About Pressure BioSciences, Inc.

Pressure BioSciences, Inc. (OTCQB: PBIO) is a leader in the development and sale of innovative, broadly enabling, pressure-based solutions for the worldwide life sciences and other industries. Our products are based on the unique properties of both constant (i.e., static) and alternating (i.e., pressure cycling technology, or PCT) hydrostatic pressure. PCT is a patented enabling technology platform that uses alternating cycles of hydrostatic pressure between ambient and ultra-high levels to control bio-molecular interactions safely and reproducibly (e.g., cell lysis, biomolecule extraction). Ourprimary focus is the development of PCT-based products for biomarker and target discovery, drug design and development, biotherapeutics characterization and quality control, soil & plant biology, forensics, and counter-bioterror applications. Additionally, major new market opportunities have emerged in the use of our pressure-based technologies in the following areas: (1) the use of our recently acquired, patented technology from BaroFold, Inc. (the "BaroFold" technology) to allow entry into the bio-pharma contract services sector, and (2) the use of our recently-patented, scalable, high-efficiency, pressure-based Ultra Shear Technology ("UST") platform to (i) create stable nanoemulsions of otherwise immiscible fluids (e.g.,oils and water) and to (ii) prepare higher quality, homogenized, extended shelf-life or room temperature stable low-acid liquid foods that cannot be effectively preserved using existing non-thermal technologies.
