ITEM 1. BUSINESS.

Overview

We are a leader in the development and sale of innovative, broadly enabling, high pressure-based platform technologies and related consumables for the worldwide life sciences, agriculture, cosmetics, food and beverage, and other key industries. Our solutions 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 safely and reproducibly control bio-molecular interactions (e.g., cell lysis, biomolecule extraction). Historically, our primary focus has been in 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. In more recent years, 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 platform) 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),to (ii) prepare higher quality, homogenized, extended shelf-life or room temperature stable low-acid liquid foods that cannot be acceptably preserved using existing non-thermal technologies and (iii), in some cases, improve the bioavailability of some poorly absorbed oils. Because of the significant market opportunity presented by UST, the Company has shifted its predominant efforts in commercializing this revolutionary platform.

On February 8, 2021, PBI announced plans to acquire the assets of a global eco-friendly agrochemical supplier. This opportunity is attractive as it has the potential of readily producing significant revenue, as well as the potential to apply the UST technology to improve some of the product line. In July 2021, a newly-formed subsidiary of PBI, PBI Agrochem, leased a warehouse in Sparks, NV, and hired a warehouse manager. See the further description of this possible transaction in Item 1 – Business – “The PBI Agrochem Platform.”

The reestablishment of previous business relationships and sales channels proceeded much more slowly during late 2021 than had been forecast by the management of the dormant agrochemicals company. As much of the historical business had been generated in California, the four-year drought conditions presented significant challenges throughout the 2022 year. The management of the dormant agrochemicals company continues to forecast an accelerating reestablishment of its previous customer base and sales, and robust global growth opportunities for its highly desirable “green” agrochemical product solutions. PBI is continuing to evaluate these agrochemical assets and the asset acquisition opportunity. The widely publicized rainfalls occurring throughout the West present both an opportunity that the drought is coming to an end as well as threat that flooded fields will be challenging to plant.

The PCT Platform

a. Description

The instruments, consumables and software used to perform PCT (the “PCT Platform”) use alternating cycles of hydrostatic pressure between ambient and ultra-high levels to safely and reproducibly control bio-molecular interactions (e.g., critical steps performed by hundreds of thousands of scientists worldwide, such as cell lysis and biomolecule extraction). Our primary focus is in making our recently released, GMP-compliant, next generation PCT-based Barocycler 2320 EXT instrument available globally to biopharmaceutical drug manufacturers to accelerate biologics development by streamlining workflows for the design, development, characterization and quality control of biotherapeutic drugs. The PCT Platform is also used in such areas as biomarker and target discovery, soil & plant biology, anti-bioterror, and forensics. We currently have hundreds of PCT instrument systems placed in approximately 200 academic, government, pharmaceutical, and biotech research laboratories worldwide. There are over 120 independent, peer-reviewed publications highlighting the advantages of using the PCT Platform in scientific research studies, many from key opinion leaders worldwide. The PCT Platform is offered through the Company’s Research Products & Services Group.

We are focused on solving the challenging problems inherent in biological sample preparation, a crucial laboratory step performed by scientists worldwide working in biological life sciences research. Sample preparation is a term that refers to a wide range of activities that precede most forms of scientific analysis. Sample preparation is often complex, time-consuming and, in our belief, one of the most error-prone steps of scientific research. It is a widely-used laboratory undertaking – the requirements of which drive what we believe is a large and growing worldwide market. We have developed and patented a novel, enabling technology platform that offers revolutionary speed and reproducible control in the sample preparation process, while revealing a far greater diversity and abundance of detectable unique analytes. It is based on harnessing the unique properties of high hydrostatic pressure. This process, which we refer to as Pressure Cycling Technology, or PCT, uses alternating cycles of hydrostatic pressure between ambient and ultra-high levels i.e., 20,000 psi or greater to safely, conveniently and reproducibly control the actions of molecules in biological samples, such as cells and tissues from human, animal, plant and microbial sources.

PCT is an enabling platform technology based on a physical process that had not previously been used to control bio-molecular interactions. PCT uses unique instrumentation that is capable of cycling pressure between ambient and ultra-high levels at controlled temperatures and specific time intervals, to rapidly and repeatedly control the interactions of bio-molecules, such as proteins, DNA, RNA, lipids and small molecules. Our laboratory instrument family, the Barocycler, and our proprietary consumables product line, which include our unique MicroTubes, MicroCaps, MicroPestles, and PULSE (Pressure Used to Lyse Samples for Extraction) Tubes, and application specific kits (containing consumable products and reagents), together make up our PCT Sample Preparation System (the “PCT SPS”).

In 2015, together with an investment bank, we formed a subsidiary called Pressure BioSciences Europe (“PBI Europe”) in Poland. We have 49% non-controlling ownership interest with the investment bank retaining 51%. As a result of subsequent changes in the Polish government, initial plans for PBI Europe have not been pursued. Throughout 2021, PBI Europe did not have any operating activities and we cannot reasonably predict when operations will commence.

Sample preparation is widely regarded as a significant impediment to research and discovery and sample extraction is generally regarded as one of the key parts of sample preparation. The process of preparing samples for genomic, proteomic, lipidomic, and small molecule studies includes a crucial step called sample extraction or sample disruption. This is the process of extracting biomolecules such as nucleic acid i.e., DNA and/or RNA, as well as proteins, lipids, or small molecules from the plant or animal cells and tissues that are being studied. Our current PCT sales and marketing efforts are based upon our belief that pressure cycling technology provides a superior solution for sample extraction when compared to other available technologies or procedures, and thus might significantly improve the quality and efficiency of sample preparation and subsequent test result.

Within the broad field of biological sample preparation, we focus the majority of our PCT and constant pressure (“CP”) product development efforts in three specific areas: biomarker discovery, precision medicine and forensics. We believe that our existing PCT and CP-based instrumentation and related consumable products fill an important and growing need in the sample preparation market for the safe, rapid, versatile, reproducible and more complete extraction of nucleic acids, proteins, lipids, and small molecules from a wide variety of plant, animal, and microbiological cells and tissues.

Biomarker Discovery and Precision Medicine

The most commonly used technique worldwide for the preservation of cancer and other tissues for long-term storage and subsequent pathology evaluation is to process them into formalin-fixed, paraffin-embedded (“FFPE”) samples. We believe that the quality and analysis of FFPE tissues is highly problematic, and that PCT offers significant advantages over current processing methods, including standardization, speed, biomolecule recovery, and safety.

Our customers include researchers at academic laboratories, government agencies, biotechnology companies, pharmaceutical companies and other life science institutions in the Americas, Europe, Asia, Africa and Australia/Pacific. Our goal is to continue market penetration in these target areas. We also believe that there is a significant opportunity to sell and/or lease additional Barocycler instrumentation to additional laboratories at current customer institutions.

b. Market

We focus most of our research and development and commercialization efforts on sample preparation and quality control analysis for genomic, proteomic, lipidomic, and small molecule studies. This market is comprised of academic and government research institutions, biotechnology and pharmaceutical companies, and other public and private laboratories that are engaged in studying genomic, proteomic and small molecule biomarkers within plant and animal cells and tissues. We elected to initially focus our resources on the market of genomic, proteomic and small molecule sample preparation because we believe it is an area that:

We believe that our existing PCT and CP-based instrumentation and related consumable products fill an important and growing need in the sample preparation market for the safe, rapid, versatile, reproducible and more complete extraction of nucleic acids, proteins and small molecules from a wide variety of plant and animal cells and tissues.

Biomarker Discovery - Mass Spectrometry

A biomarker is any substance (e.g., protein, DNA) that can be used as an indicator of the presence or absence of a particular disease-state or condition, and/or to predict or measure the progression and effects of therapy. Biomarkers can help in the diagnosis, prognosis, therapy selection and monitoring, prevention, surveillance, control, and cure of diseases and medical conditions.

A mass spectrometer is a laboratory instrument used in the analysis of biological samples, often focused on proteins, in life sciences research. It is frequently used to help discover biomarkers. According to the November 2017 published market report by Markets and Markets “Mass Spectrometry Market by Application (Pharmaceuticals, Biotechnology, Environmental testing), Platform (Single mass spectrometry (Quadrupole, TOF & Ion Trap), Hybrid mass spectrometry (Triple Quadrupole, QTOF & FTMS)) – Global Forecast to 2022, the global mass spectrometry market is expected to grow from USD $3.44 billion in 2016 to USD $5.27 billion by 2022, at a CAGR of 7.4% from 2016 to 2020. We believe PCT and CP-based products offer significant advantages in speed, reproducibility, and quality completeness of results, compared with current techniques used in the preparation of samples for mass spectrometry analysis.

Biomarker Discovery – Precision Medicine

Precision medicine is an approach to patient care that allows doctors to select treatments that are most likely to help patients based on a specific biomolecular understanding of their disease. The goal of precision medicine is to facilitate selection and/or development of treatments are tailored to the unique biomolecular variations specific to each person’s disease.

A significant roadblock in obtaining necessary information to advance precision medicine – specifically in proteogenomics, is sample preparation and the time required using conventional methods. We believe our PCT workflows address this roadblock by providing a rapid, reproducible means of extracting biomarkers from patient samples in a clinically relevant timeframe of 2 hours.

Biomarker Discovery – Cancer and Tumor Microenvironment

The most commonly used technique worldwide for the preservation of cancer and other tissues for subsequent pathology evaluation is formalin-fixation followed by paraffin-embedding, or FFPE. We believe that the quality and analysis of FFPE tissues is highly problematic, and that PCT offers significant advantages over current processing methods, including standardization, speed, biomolecule recovery, and safety.

Biopharmaceutical Quality Control

A critical step in biopharmaceutical manufacturing processes is quality control, involving characterization of the resulting biotherapeutics via peptide mapping and analysis of post-translational modifications. Peptide mapping can be used in drug discovery and throughout the manufacturing process for quality control between batches to produce a unique ‘fingerprint’ of an individual protein and to compare this with the theoretical gene-derived amino acid sequence. Using conventional methods this process can take overnight or more. We believe our PCT workflows offer a significant advantage to this process by offering a significant reduction in time and improvement in reproducibility with a GMP compliant platform. Many protein-based pharmaceuticals undergo specific enzymatic and chemical modifications (such as glycosylation, when specific carbohydrate moieties, glycans, are attached to the protein core, thus helping them remain active longer in the patient’s bloodstream). Like peptide mapping, analysis of glycans, also critical quality attributes of biologic drugs, requires tedious sample preparation steps that can be significantly accelerated and rendered more reproducible by PCT workflows.

Our customers include researchers at academic laboratories, government agencies, biotechnology companies, pharmaceutical companies and other life science institutions in the Americas, Europe, Asia, Africa, and Australia/Pacific. Our goal is to continue aggressive market penetration in these target areas. We also believe that there is a significant opportunity to sell and/or lease additional Barocycler instrumentation to additional laboratories within current customer organizations.

Sample Extraction Process

The process of preparing samples for genomic, proteomic and small molecule studies includes a crucial step called sample extraction or sample disruption. This is the process of extracting nucleic acid i.e., DNA and/or RNA, proteins or small molecules from the plant or animal cells and tissues that are being studied. Sample preparation is widely regarded as a significant impediment to research and discovery and sample extraction is generally regarded as one of the key parts of sample preparation. Our current commercialization efforts are based upon our belief that pressure cycling technology provides a superior solution to sample extraction compared with other available technologies or procedures and can thus significantly improve the quality of sample preparation, and thus the quality of the test result.

c. Products

We believe our PCT and CP products allow researchers to improve scientific research studies in the life sciences field. Our products are developed with the expectation of meeting or exceeding the needs of research scientists while enhancing the safety, speed and quality that is available to them with existing sample preparation methods.

Barocycler Instrumentation

Our Barocycler product line consists of laboratory instrumentation that subjects a sample to cycles of pressure from ambient (approximately 14.5 psi) to ultra-high levels (20,000 psi or much greater) and then back to ambient, in a precisely controlled manner.

Our instruments (the Barocycler 2320EXT, the HUB440 and the HUB880) use cycles of high, hydrostatic pressure to quickly and efficiently break up the cellular structures of a specimen to release proteins, nucleic acids, lipids and small molecules from the specimen into our consumable processing tubes, referred to as our PULSE Tubes and MicroTubes. Our instruments have temperature control options (on-board heating via internal heating jacket or heating and chilling via an external circulating water or oil bath), automatic fill and dispensing valves, and an integrated touchscreen for interfacing with an onboard micro-processor or computer. The microprocessor, computer or laptop computer are capable of saving specific PCT protocols, so the researcher can achieve maximum reproducibility for the preparation of nucleic acids, proteins, lipids, or small molecules from various biological samples. Our Barocycler instruments, consumable products and application specific kits make up our PCT Sample Preparation System.

Barocycler 2320EXTREME - The Barocycler 2320EXT is the flagship of the Company’s Barocycler line of PCT-based instruments. It weighs approximately 80lbs, delivers a maximum pressure of 45,000 psi, and can process either up to 16 MicroTubes simultaneously. The working temperature range is 4 – 95ºC and is controlled via an on-board electric heating jacket or external circulating bath. All tests are entered and recorded on a touch screen interface. Information from each test run (pressure profile, cycle number, and temperature) is recorded and can be stored on the instrument, on a USB drive, or networked into the user’s lab computer system. Pressure profiles can be manipulated in a number of ways, including static high pressure holds and pressure ramp programs. The Barocycler 2320EXT is pneumatic and requires an input air source of only 100psi to achieve and cycle at high pressure.

The Barocycler 2320EXT was developed to support the PCT-HD/PCT-SWATH application. PCT-HD enables faster, less cumbersome and higher quality processing of biopsy tissues. With homogenization, extraction, and digestion of proteins occurring in a single PCT MicroTube under high pressure, this protocol can yield analytical results in under four hours from the start of tissue processing. PCT-HD was developed by our scientists and engineers in collaboration with Professor Ruedi Aebersold and Dr. Tiannan Guo of the Institute of Molecular Systems Biology, ETH Zurich, and the University of Zurich, in Switzerland. Drs. Aebersold and Guo combined PCT-HD with SCIEX’s SWATH-Mass Spectrometry – calling the resulting method “PCT-SWATH”.

Barocycler HUB440 –We believe the Barocycler HUB440 is the first portable, ready to use, “plug-and-play” high pressure generator for the laboratory bench. The Barocycler HUB440 is capable of creating and controlling hydrostatic pressure from 500 psi to 58,000 psi and is designed for easy and flexible interfacing with a wide variety of user-specified pressure vessels. It is computer controlled and runs on software that was developed by us to allow data logging and sophisticated algorithms for controlling pressure and temperature. We own the rights and have a license to use the specialty LabVIEW software. We believe that over the coming years, the Barocycler HUB440 may become one of the main products in our pressure-based instrument line.

Barocycler HUB880 - The Barocycler HUB880 is a compact, portable, bench-top, ultra-high pressure generator with vessel interface flexibility similar to the HUB440, that uses an air pressure-to-liquid pressure intensifier allowing the user to generate fluid pressure as high as 90,000 psi with input air pressure of just 126 psi. The HUB880 can be operated through a simple front panel or controlled using an optional external Data Acquisition and Control Module for dynamic pressure control. We believe that the HUB880 will be well accepted by scientists that need to achieve super high pressure, such as those working in the life science research, food safety and vaccine industries.

The Shredder SG3 –The Shredder SG3 is a low shear mechanical homogenization system for use with tough, fibrous and other difficult-to-disrupt tissues and organisms. The Shredder SG3 System uses a variety of Shredder PULSE Tubes to directly and rapidly grind a biological sample which, when combined with selected buffers, can provide effective extraction of proteins, DNA, RNA, lipids and small molecules from tissues and organisms. The Shredder SG3 is also used to isolate intact and functional mitochondria from tissues. The Shredder SG3 features a three-position force setting lever, which enables the operator to select and apply reproducible force to the sample during the shredding process and eliminates the need for the operator to exert force for long periods when processing one or more samples.

Barocycler Consumable Products

PCT MicroTubes – PCT MicroTubes are made from a unique fluoropolymer, fluorinated ethylene propylene (FEP). FEP is highly inert and retains its integrity within an extremely wide temperature range (-200°C to 100°C), while providing important limited flexibility behavior for PCT applications. MicroTubes hold a maximum total volume of 150 microliters. PCT MicroTubes must be used with either PCT-MicroCaps or PCT-MicroPestles.

PCT-MicroCaps – PCT MicroCaps are made from polytetraflouroethylene (PTFE). The PCT MicroCaps are available in three sizes to accommodate total sample volume: 50, 100 and 150uL. 50uL MicroCaps are used with samples ≤50uL, 100uL MicroCaps are used with samples between 50-100uL, and 150uL MicroCaps are used with samples between 100-150uL.

PCT-Micro Pestle - PCT μPestles are made from polytetrafluoroethylene (PTFE), a synthetic fluoropolymer of tetrafluoroethylene, also known as Teflon (by DuPont Co). PTFE is practically inert; the only chemicals known to affect it are certain alkali metals and most highly reactive fluorinating agents. PCT μPestles, in conjunction with PCT MicroTubes, are designed to enhance the extraction of proteins, lipids, DNA, RNA and small molecules from minute amounts (0.5 – 3.0 mg) of solid tissue in extraction reagent volumes as low as 20-30 μL. PCT MicroTubes and PCT μPestles use PCT to effectively disrupt soft tissues and lyse their cells. As a result, the tissue sample trapped between the MicroTube walls and the μPestles shaft is crushed on every pressure cycle. This mechanical action, combined with the extraction ability of the buffer under high pressure, results in highly effective tissue homogenization and extraction.

PCT μPestles and PCT MicroTubes, together with a PBI Barocycler, comprise the PCT Micro-Pestle System, which provides a fast, safe, and efficient means of extraction from extremely small amounts of solid samples such as soft tissue biopsies. The PCT μPestle System can be used in any PBI Barocycler.

We believe our development of these various consumable products has helped, and will continue to help, drive the adoption of PCT within the life sciences market.

d. Competition

We compete with companies that have existing technologies for the extraction of nucleic acids, proteins, lipids, and small molecules from cells and tissues, including methods such as mortar and pestle grinding, sonication, rotor-stator homogenization, French Press, bead beating, freezer milling, enzymatic digestion, and chemical dissolution. We believe that there are a number of significant issues related to the use of these methods, including: complexity, sample containment, cross-contamination, shearing of biomolecules of interest, limited applicability to different sample types, ease-of-use, reproducibility, and cost. We believe that our PCT Sample Preparation System offers a number of significant advantages over these methods, including:

To be competitive in the industry, we believe we must be able to clearly and conclusively demonstrate to potential customers that our products provide these improved performance capabilities. We strongly believe that our PCT Sample Preparation System is a novel and enabling system for genomic, proteomic, and small molecule sample preparation. As such, many users of current manual techniques will need to be willing to challenge their existing methods of sample preparation and invest time to evaluate a method that could change their overall workflow in the sample preparation process, prior to adopting our technology.

Further, we are aware that the cost of the PCT Sample Preparation System may be greater than the cost of many of the other methods currently employed. Consequently, we are focusing our sales efforts on those product attributes that we believe will be most important and appealing to potential customers; namely speed, versatility, analyte diversity and abundance, reproducibility, quality, and safety.

e. Manufacturing and Supply

We currently manufacture and assemble the Barocycler 2320EXT, Barocycler HUB440, HUB880, the SHREDDER SG3, and most of our consumables at our South Easton, MA facility. We will regularly reassess the tradeoffs between in-house assembly versus the benefits of outsourced relationships for of the entire Barocycler product line, and future instruments.

We utilize a few contract manufacturers of certain parts for our Barocycler product line. They provide us with precision manufacturing services to meet our specific application and operational requirements.

At this time, we believe that this approach is the most cost-effective method for us to produce and market ISO Certified, CE and CSA Marked instruments.

f. Research and Development

Our research and development activities are split into two functional areas: Applications Development and Engineering.

Collaboration Program

Our Collaboration Program is an important element of our business strategy. Initiating a collaboration with a researcher involves the installation of a Barocycler instrument for an agreed upon period of time of approximately three to twelve months, a financial commitment that is beneficial to both the collaborator and PBI, and the execution of an agreed upon work plan. Our primary objectives for entering into a collaboration agreement include:

Since we initiated our collaboration program, third party researchers have cited the use of our PCT platform in over 120 peer-reviewed publications and dozens of scientific presentations. We believe that this program has provided and continues to provide us with independent and objective data about PCT from well-respected laboratories in the United States and throughout the rest of the world. We believe this program has been responsible for the sale of multiple Barocycler instruments over the past few years and will continue to help to increase the sales of instrument systems in the future.

Other Fields of Use and Applications for PCT

Our research and development efforts have shown that, in addition to genomic, proteomic, lipidomic, and small molecule sample preparation, PCT is potentially beneficial in several other areas of the life sciences, including pathogen inactivation, protein purification, control of chemical (particularly enzymatic) reactions, and immunodiagnostics. Other applications in the sample preparation market include forensics and histology, as discussed above. Our pursuit of these markets, however, depends on several factors, including our success in commercializing PCT in the area of sample preparation, our judgment regarding the investment required to be successful in these areas, the value of these markets to PBI, and the availability of sufficient financial resources. Below is a brief explanation of each of these additional potential applications and a short description of why we believe PCT can be used to improve scientific studies in these areas.

Protein Purification

Many vaccines and drugs are comprised of proteins. These proteins need to be purified from complex mixtures as part of the manufacturing process. Current purification techniques often result in the loss of a significant amount of the protein. Therefore, any method that could increase the amount of protein being recovered in the purification step, could subsequently lead to a reduction in cost to the manufacturer. We believe we have successfully generated proof-of-concept that PCT can satisfy this need. We believe that compared with current purification procedures, a process that uses PCT has the potential to increase protein recovery, increase the quality of the product, and lower production costs. We have been issued U.S. patents in this area.

Pathogen Inactivation

Biological products intended for human use, such as blood, vaccines and drugs, are put through rigorous processing protocols in an effort to minimize the potential of that product to transmit disease. These protocols may include methods to remove infectious materials such as pre-processing testing, filtration or chromatography, or methods to inactivate infectious agents that are not captured in the removal steps such as pasteurization, irradiation and solvent detergent inactivation. Notwithstanding current diligence in both the removal and inactivation steps, significant concern remains that some pathogens (e.g., bacteria, viruses, spores) capable of transmitting infection to recipients may not be removed or inactivated with current procedures. In addition, some removal and inactivation methods may not be useful because of cost, safety, ease-of-use or other practical concerns. To that end, we believe that a superior inactivation method is needed that can safely, rapidly and inexpensively inactivate pathogens in blood, vaccines and drugs without the need for chemical or other potentially toxic additives. We have successfully generated proof-of-concept that PCT can satisfy this need. We believe that compared with current procedures, a process that uses PCT has the potential to increase safety and yield, lower cost and decrease the potential side effects of current methods. We have been issued U.S. patents for this PCT-dependent inactivation technology.

Control of Chemical (Particularly Enzymatic) Reactions

Chemical reactions encompass many important interactions in nature. Methods used to control chemical reactions could have a positive effect on the quality, speed, and overall result of the reaction. The control and detection of chemical reactions is particularly useful in the biotechnology field for synthesizing and characterizing such molecules as nucleic acids and polypeptides. We believe that PCT offers distinct advantages in controlling chemical reactions over current methods, since PCT can provide precise, automated control over the timing and synchronization of chemical reactions, particularly enzymatic reactions. We have been issued U.S patents in this area.

Immunodiagnostics

Many tests used in the clinical laboratory today are based on the formation of a complex between two proteins, such as an antigen and an antibody. Such “immunodiagnostic” methods are used for the detection of infectious agents such as the human immunodeficiency virus (“HIV”), hepatitis viruses, West Nile virus, and others, as well as for endocrine, drug testing and cancer diagnostics. We have generated proof-of-concept that PCT may be used to control biomolecular interactions between proteins, such as antigens and antibodies. We believe this capability may provide a greater degree of sensitivity and quantitative accuracy in immunodiagnostic testing than that offered by methods that are available today. We have been issued U.S. patents in this area.

Extended Service Contracts

We offer extended service contracts on our laboratory instrumentation to all of our customers. These service contracts allow a customer who purchases a Barocycler instrument to receive on-site scheduled preventative maintenance, on-site repair and replacement of all worn or defective component parts, and telephone support, all at no incremental cost for the life of the service contract. We offer one-year and four-year extended service contracts to customers who purchase Barocycler instruments.

The BaroFold Platform

a. Description

The need for the efficient production of recombinant protein biopharmaceuticals has grown rapidly and demand for them will continue to grow because of their high specificity and efficacy. Protein drugs are being manufactured via expression in a variety of host organisms. With the rapid growth in biosimilars (less expensive versions of popular biopharmaceuticals that are manufactured and marketed after the expiration of the original patents), protein expression in bacteria is beginning to play a major role in this industry, particularly when the biological activity of the protein product is not dependent on post-translational modifications that only occur in more complex organisms.

Overexpression of proteins in bacteria often results in the accumulation of the protein product in inactive insoluble deposits inside the cells, called inclusion bodies. Inclusion bodies protect the protein of interest from degradation and present a simple and convenient ways to extract and purify it. Moreover, if the protein of interest is toxic or lethal to the host cell, then inclusion body expression may be the only available production method. However, the challenge of protein production in bacterial systems most often lies in conversion of inactive and misfolded proteins in the inclusion bodies into soluble, properly folded bioactive products. This conversion process is called protein refolding.

Traditional methods of protein refolding rely on using high concentrations of chemical denaturants and detergents to unfold misshapen proteins, and to disentangle and dissolve inactive aggregated proteins and to dissolve them, followed by up to 100-fold dilution or dialysis to remove interfering chemicals and then letting the proteins refold into their desired active forms. Since chemically-driven unfolding is harsh, it tends to destroy most of the tertiary (folding) protein structure, some of which could be beneficial for subsequent refolding. Moreover, dilution- or dialysis-based methods take a long time and produce very low yields of refolded protein, while most of the unfolded protein material tends to get lost into irreversible aggregation. Overall, traditional refolding methods are usually inefficient, include multiple costly steps and have very low recovery yields. Pressure-mediated disaggregation and unfolding and refolding of proteins offers an attractive pathway for achieving much higher yields of correctly folded proteins with desired efficaciousness, produced at much lower cost, versus traditional chemically driven methodologies.

Acquisition of BaroFold’s PreEMT™ high-pressure protein refolding technology in December 2017

Our acquisition of the assets of BaroFold, Inc. have significantly increased PBI’s intellectual property portfolio in high-pressure technologies with the addition of eight issued and several pending patents. These patents give PBI the ability to operate in several important areas for biologics research and manufacturing: protein folding, re-folding and disaggregation. The patents also provide PBI the right to grant licenses to third parties to practice the BaroFold technology in both research laboratories and in biopharmaceutical manufacturing.

Biopharmaceutical products are typically large-molecule protein therapeutics produced via complex biological manufacturing processes that can result in undesirable protein misfolding and aggregation outcomes. Misfolded or aggregated proteins typically lack therapeutic activity and can present health risks to patients, requiring robust remediation within pharmaceutical manufacturing processes. The BaroFold technology improves the quality of manufacturing, decreases manufacturing costs (as much as $2-10M/year per commercial biologic drug), and facilitates achievement of proper activity from difficult-to-manufacture proteins.

BaroFold technology utilizes high pressure instead of, or in synergy with, chemical denaturants, offering significantly milder conditions for unfolding and disaggregation of proteins in inclusion bodies. As a result, subsequent refolding can be carried out faster, more efficiently, and in much smaller volumes. Pressure-based unfolding of proteins in inclusion bodies tends to only partially unfold the protein and preserve some beneficial structures that could help to guide the refolding process into the desired outcomes. Consequently, higher yields of active protein and faster manufacturing turn-around further lower the cost of biopharmaceutical production. Moreover, lower requirements for harsh chemical reagents in high pressure refolding processing result in the decrease or elimination of associated hazardous waste generated from chemical removal processes, leading to further cost reduction and protection of the environment.

The instruments, consumables and software used to practice the BaroFold technology (the “BaroFold Platform”) can be used to significantly lower the cost, boost production yield, and improve the quality of protein therapeutics. It employs high pressure for the disaggregation and controlled refolding of proteins to their native structures at yields and efficiencies not achievable using existing technologies. The BaroFold Platform has been shown to remove protein aggregates in biotherapeutic drug manufacturing, thereby improving product efficacy and safety for both new-drug entities and biosimilar products. The BaroFold Platform can help companies create novel protein therapeutics, accelerate therapeutic protein development, manufacture follow-on biologics, and significantly optimize life-cycle management of protein therapeutics. It is scalable and practical for standard manufacturing processes. This unique technology platform can help protein-based biopharmaceutical companies create and manufacture high quality, novel protein therapeutics and lower the cost of existing formulations. Research and manufacturing licenses are available.

b. Market

According to a report entitled “Pharmaceutical market: worldwide revenue 2001-2022 by Matej Mikulic published on February 3, 2023, “the global pharmaceutical market has experienced significant growth in recent years. For 2022, the total global pharmaceutical market was estimated at 1.48 trillion U.S. dollars.”

We believe that biopharmaceuticals offer several benefits, such as highly effective and potent action, fewer side effects, and the potential to actually cure diseases rather than merely reduce disease burden or treat the symptoms, which have significantly increased the demand for biopharmaceutical products.

The predominant majority of biopharmaceutical products are recombinant proteins. Typical examples of such proteins are vaccines, monoclonal antibodies (MAbs), growth factors (such as Erythropoietin), hormones (such as insulin or HGH), receptor ligands, recombinant enzymes (Caspase, Cathepsin, etc.), blood factors and other therapeutic and research reagent proteins. Recombinant protein production can be done in bacteria or in cell cultures derived from higher organisms. Due to significant time and cost savings, attention to protein production in bacterial hosts has recently spiked, predominantly driven by rapid growth of biosimilars, antibody-drug conjugates (ADCs) and fusion proteins that are lethal to non-bacterial host cells. A major area of challenge in the biopharmaceuticals industry results from suboptimal folding configurations and/or agglomeration of proteins during production and storage, requiring subsequent remediation via unfolding and controlled refolding of these therapeutic proteins into their optimal configurations. Following initial penetration and acceleration through conversion of market share from traditional chemical methods, the growth of the protein refolding business is expected to follow the growth trajectory of the entire biopharmaceutical market.

Our BaroFold platform technology has been shown not only to save manufacturing costs and time, but to boost protein yield and minimize protein immunogenicity, resulting in greater efficacy and safety for the patient.

Moreover, PBI’s Barocycler line of products can also be utilized in accelerated protein stability testing to guide biopharmaceutical formulation development. PBI has initiated several collaborations, including a co-marketing agreement with RedShift BioAnalytics, Inc., and a research collaboration with the University of Delaware (see the Research and Development section below).

c. Products

Instruments: Barocycler 2320 EXT - a convenient screening tool for protein refolding optimization

Originally developed within the framework of our PCT platform business as a tool for biological sample preparation (as described above), our Barocycler 2320EXT instrument features a “ramp mode” in its control software that makes it ultimately suitable for performing research-scale experiments for protein refolding and disaggregation on a laboratory bench scale. Each protein molecule is biochemically unique and, while pressure is highly efficient in solubilization of practically any misfolded protein contained within inclusion bodies, a unique chemical environment may be required to persuade each unfolded protein molecule to refold into a stable biologically active state. Therefore, development of protein refolding methods requires screening experiments necessary to determine the most optimal composition of the chemical milieu for each protein of interest. The Barocycler 2320EXT is ideally suited for such experiments, providing researchers with abilities to process up to 12 specimens per batch in varying chemical environments. We believe that availability of this affordable screening tool will promote adoption of the high-pressure refolding approach among biopharmaceutical process development teams and academic researchers involved in development of protein biopharmaceuticals. The same instrument is also uniquely suited for studies of thermodynamics of protein aggregation and accelerated protein stability tests.

BaroFold Contract Services

Our BaroFold contract services can be used to significantly impact and improve the quality of large-molecule protein biotherapeutics. These services employ high pressure manipulations for the disaggregation and unfolding of proteins to their native structural states and then controlled refolding of the proteins to the desired therapeutically active state, at yields and efficiencies not achievable using existing technologies. The BaroFold Platform has been shown to eliminate protein aggregation during biotherapeutic drug manufacturing and storage, thereby improving product yield, efficacy and safety for both new-drug entities and biosimilar products. The BaroFold platform can help companies create novel protein therapeutics, accelerate therapeutic protein development, manufacture follow-on biologics, and enable life-cycle management of protein therapeutics. It is scalable and practical for standard manufacturing processes. This unique technology platform can help protein-based biopharmaceutical companies create and manufacture high quality, novel protein therapeutics and lower the cost of existing formulations. Research and manufacturing licenses are available.

e. Competition

Over two decades, BaroFold, Inc. built an intellectual property portfolio centered around the use of hydrostatic pressure for protein refolding and disaggregation. Following BaroFold’s acquisition by PBI in 2017, this portfolio, combined with the PBI patents in adjacent areas, puts PBI in a unique position worldwide to commercialize, practice and license out the right to practice high pressure protein refolding, disaggregation and accelerated stability testing. There is no direct competition to PBI that is using high pressure for these applications. Competing traditional approaches use chemicals for refolding and appear inferior in many aspects, as described above.

f. Manufacturing and Supply

Manufacturing of the Barocycler 2320EXT has been covered above, since this instrument shares its utility with applications of PCT technology platform. The PCT MicroTube consumable line is also shared between these two application areas.

PBI currently develops GMP-compliant, pilot-scale, high-pressure systems for processing of protein batches up to 10L in volume at pressure up to 60,000 psi.

In order to provide access for our customers to manufacturing-scale high pressure equipment, PBI is currently in negotiations with several HPP (High Pressure Processing) equipment vendors supplying large pressure systems to food manufacturers. Upon successful feasibility studies conducted by customers themselves, or within the framework of BaroFold Contract Services, PBI will act as a contractor to assist protein refolding customers in scaling up the process and identifying, procuring and validating appropriate large-scale equipment for high pressure protein refolding.

g. Research and Development

The PBI team has gained access to a significant body of research data through acquisition of the assets of BaroFold, Inc. BaroFold has spent over two decades perfecting high-pressure protein refolding applications and produced many publications and patents (see below). Our team’s experience in high pressure refolding is being used in Contract Service work currently offered by PBI to our biopharmaceutical customers, as described above. As an equipment vendor, PBI has a goal of taking advantage of these R&D instrument assets and turning a benchtop high pressure protein refolding solution into a convenient, popular and easily accessible workflow for thousands of laboratories worldwide. As the knowledge about this method spreads and feasibility of great economic impact of utilizing this approach at a production scale is demonstrated, PBI plans to license high pressure refolding methods to its biopharmaceutical customers.

Many protein biopharmaceuticals must be kept in solution. Any physical factors such as exposure to temperature fluctuations in storage and shipment, mechanical vibration, exposure to light, etc., could promote protein aggregation, if the biotherapeutic protein is stored in a suboptimal chemical environment. Protein aggregates tend to be highly immunogenic, i.e., causing a patient’s immune system to recognize protein drug as a foreign object and destroy it, leading to undesired inflammatory response and counteracting the desired therapeutic effect. Each protein drug may require optimization of its chemical environment (formulations development) to guarantee maximal stability and shelf life.

Meanwhile, high pressure is a convenient tool for controlled protein unfolding. Partially unfolded proteins tend to aggregate more rapidly. Brief exposure of the protein drug in a specific formulation to a “pressure shock” can be used to promote aggregation, allowing researchers to screen for best formulations that prevent drug aggregation in a matter of only a few days.

Additionally, several new applications of high pressure in biopharmaceutical development are stemming from a combined BaroFold and PBI intellectual property portfolio. One of these highly promising applications, namely, pressure-assisted accelerated protein stability testing, is currently being developed by PBI’s R&D team in collaboration with the Center for Biomanufacturing Science and Technology of the University of Delaware, headed by Professor Christopher J. Roberts. Conventional approaches for accelerated stability testing utilize exposure to high temperature. Since thermal effects on proteins are stochastic (i.e., random), there is little chance that every protein molecule will follow the same fate after thermal shock. Pressure exerts its effect on all protein molecules of the same type/conformation in exactly the same manner, making the pressure shock more effective in such studies. Our collaborative research program with Professor Roberts’s team is directed towards development of validated workflows for high pressure accelerated stability testing.

The UST Platform

a. Description

Animals and plants are water-based life forms. As such, they do not absorb oils very effectively, orally, transdermally or in any other manner. By creating very small particles (<100nm) of oil and water, we are able to change many of the characteristics of these oils, including stability, transparency, and absorbability. The UST™ Platform is based on the use of intense shear forces generated from ultra-high pressure (greater than 20,000 psi) discharged through a proprietary dynamically-controlled nanometer-scale valve orifice. UST has been shown to turn hydrophobic extracts of desired oil-soluble active molecules into stable, effectively water-soluble formulations on a laboratory and small process production scales, with a clear pathway to scale up for large scale production requirements. The UST Platform offers the potential to produce stable nanoemulsions of oil-like products in water. Such formulations could potentially have enormous success in many markets, including pharmaceuticals, nutraceuticals (such as medically important plant oil extracts like CBD-enriched plant oil soluble in water), cosmeceuticals and personal care products, liquid foods and beverages, agrochemicals, as well as inks, paints, lubricants and other industrial products. We believe that UST has the potential to play a significant role in a number of commercially important areas, including (i) the creation of stable nanoemulsions of otherwise immiscible fluids (e.g., oils and water), and (ii) the preparation of higher quality, homogenized, extended shelf-life or room temperature stable low-acid liquid foods that cannot be effectively preserved using existing non-thermal technologies, e.g., dairy products.

UST is an emerging technology that combines intense fluid shear forces with an instant, short-lived burst of heat achieved by specialized high-pressure equipment that can produce commercially sterile, pumpable, homogeneous fluid products. The UST process can provide energetic cellular disruption that results in the inactivation of bacteria, bacterial spores, viruses, and enzymes. Depending on operating conditions, low nano-scale emulsions (nanoemulsions) of oil and water mixtures can be produced that have been shown to have improved room-temperature shelf stability, and superior sensory profiles (taste, smell, texture and appearance). Of particular importance, oil-based active components delivered in such extreme nano-emulsions in water facilitates greatly improved absorption and bioavailability in the water-based biochemistry of humans, animals and plants, allowing for much lower loading quantities of actives required in manufacture, while ensuring safer and more controlled effective dosing.

The Company received its second US patent in 2021 to complement two patents in China on UST, focused on a low cost, scalable approach for product manufacturing. The Company believes this method can find use in various nanoemulsion applications for pharmaceutical (e.g., drug delivery), biotechnology (e.g., protein recovery, biomolecule extraction), agrochemical, cosmetics, and food (e.g., shelf-stable “clean label” products). We plan to design, develop, manufacture, and market UST-based production instruments, services and production to the life sciences and other industries. We initiated the process to build full-scale UST systems initially at two sites, in order to address current customer demands and the belief that a large number of foods, cosmetics/skincare, nutraceuticals, pharmaceutical, and other companies will follow.  Our business model for UST is focused on service contracts for product development, demonstration and optimization, followed by tolling for production at small and intermediate scales, and finally by establishment of lease and licensing arrangements with companies desiring to control and integrate UST production in-house.

b. Market

In 2019, we focused efforts on developing and demonstrating the UST protocol and seeding early adopters, which would provide insights into market, formulation, product development, and ultimately end product requirements. Our initial market focus has been on cannabis extracts, as this market’s unmet needs for nanoemulsions solutions offer high visibility and ready access to funding, versus many other important target markets, such as cosmetics, food and beverage, nutraceutical, pharmaceutical, and industrial fluids and lubricants. In 2020, we refined the Ultra Shear Technology ™ K45 instrument (the “BaroShear”) allowing us to run samples for multiple potential customers, which demonstrated the goal of producing room-temperature-stable, nearly mono-disperse, low-droplet-size nanoemulsions, validated by excellent transparency. (Transparency is achieved when nanoemulsion droplet sizes are well below ~150nm, i.e. smaller than the wavelength range of visible light – an important indicator of achievement of extremely low-scale nanoemulsions.)

We also moved forward in the development of the BaroShear Mini: a bench-top, laboratory-based instrument for research, formulation, and small volume processing; and the BaroShear Max: a high-volume, industrial-scale, clean-in-place (CIP), production-scale instrument.

In 2022, we demonstrated that our CBD nanoemulsion was stable for more than 30 months at room temperature or refrigerated conditions, and after repeated freeze/thaw events.  At the time of this publication, that product has remained stable for more the 30 months. We shipped the first UltraShear Max system to our partners at The Ohio State University.  We also initiated to process of setting up two bi-coastal facilities capable of meeting the development and production needs for several customers.  In the last month of the year, we shipped our first commercial batch and announced important commercial relationships in both the cannabis market and cosmeceuticals. In 2023, we plan to commercialize UST in multiple market segments.

c. Products

The Ultra Shear Technology™ platform instrument portfolio is currently comprised of three models for use in research, formulation, and processing of oil and water nanoemulsions.

d. Customers

Cannabis extracts, cosmecetical & personal care products, liquid foods & beverages, nutraceuticals, pharmaceuticals, agrochemicals, inks, paints, lubricants and other industrial products, and researchers and processors interested in developing stable, water-soluble nanoemulsions for any application.

e. Competition - High Pressure

The following companies are either direct or indirect competitors of PBI:

f. Manufacturing and Supply

PBI’s current commercialization strategy is to initially produce UST-processed bulk nanoemulsion products for companies in a variety of markets. These concentrated products will either be used as a final form or infused into another product and packaged by our customers. The development of both the machines and processed will be handled by PBI’s development and engineering team, with manufacturing at a combination of our locations, and utilizing selected Contract Manufacturing Organization (CMO), and, ultimately, with the end customers, where appropriate. We believe the demand for these high value concentrates will generate necessary revenues and allow us to begin production and marketing of devices for sale within two years. At that time, aftermarket service and support will initially be handled by PBI’s service and repair staff. As unit placements grow, we will investigate expansion of PBI’s service and support organization or augment it with external partners.

The PBI Agrochem Platform

In February 2021, PBI announced a signed Letter of Intent to acquire the assets and senior management of a dormant company with an extensive portfolio of innovative agrochemical products, utilizing natural product oils as active ingredients (similar to the use of orange oil or neem oil for pest control). With the intense and growing focus of consumers and governments on the long term environmental and health challenges presented by many conventional agrochemical products, this new class of “green” essential oil agrochemicals that are effective, while also considered safe for humans and animals represent a highly attractive and high-growth segment of the agrochemicals market.

The ability of PBI to further differentiate the efficiency and cost-effectiveness of these products versus traditional agrochemicals, through the application of UST to obtain all of the benefits of extremely low droplet-size nanoemulsions, offers a compelling growth and profitability acceleration opportunity in the agrochemicals business sector. While PBI is pursuing a lease and license model for the rollout of its UST platform into other business sectors, we elected to test a direct participation model in the agrochemical applications sector.

In July 2021, PBI established PBI Agrochem, Inc., a wholly owned agrochemicals subsidiary, in order to purchase up to $1M of “green” agrochemical products from the targeted acquisition, to allow the management of the dormant agrochemicals company to demonstrate the reestablishment of previous business relationships and sales channels, and to provide access to early agrochemical sales revenues for PBI (prior to closing the asset acquisition transaction). PBI Agrochem leased a warehouse near Sparks, NV and hired a warehouse manager to facilitate the shipping, storage and management of the “green” agrochemicals inventory. That management of the dormant agrochemicals company has not been effective in the reestablishment of sales channels and revenues, but PBI Agrochem is continuing to focus on developing this important area of market opportunity.

The year ended December 31, 2022 was very disappointing as sales of AgroChem did not materialize as expected. The historic prolonged drought in California and much of the West significantly impacted the agricultural markets. With the profound shift in weather at the end of 2022, there are some signs that the market will be more receptive in 2023.

Other

a. Sales and Marketing

Our marketing and sales functions are led by John Hollister, our Director of Sales and Marketing. Mr. Hollister oversees and directs all marketing and sales activities, including trade show attendance and sponsorship, on-line advertising, website maintenance and improvement, search engine optimization, creation and dissemination of newsletters, market research initiatives, the arrangement of on-location seminars, lectures, and demonstrations of instrumentation and consumables capabilities, and the supervision of our sales and marketing personnel. Mr. Schumacher is also responsible for the overall coordination of our collaboration programs, from initial set-up, research plan design, and training, service, and data analysis. Some of these responsibilities are shared with other departments such as Research and Development, but marketing and sales drives the collaborative process. Mr. Hollister is also responsible for the continued coordination and support of our foreign distribution partners. The Company is in the process of recruiting a field salesperson.

Our sales and marketing efforts are centered on using the independent data developed and disseminated by our collaboration partners to help drive the installed base of our PCT Sample Preparation System, BaroFold services, and BaroShear UST platform. The development of scientific data by our partners and our internal researchers provides our sales and marketing staff with additional tools that are essential in selling existing and newly developed paradigm-shifting, high-value technologies and services. We believe that partnering with seasoned, capable equipment distribution partners in the cannabis and other laboratory and process manufacturing markets will drive lead generation and purchase orders faster than if we were to build our own sales force.

b. Marketing Strategy

We recognize that our enabling PCT, BaroFold, and UST pressure platforms are powerful, novel platform technologies. We also recognize that the power of pressure is not yet widely understood, appreciated and utilized by researchers and engineers in today’s laboratories and prospective industrial partners. Our first goal is to greatly broaden the awareness of pressure and its applications among research scientists and to ensure they know that these technologies exist through our high-pressure instruments, requisite consumables, and unique services. To accomplish this expansion of knowledge about the power of pressure and the subsequent adoption of our pressure-based technology platforms, we have developed and are implementing a multi-faceted approach to marketing our products and services.

Key Opinion Leaders and Publications

To initially reach scientists, we have established collaborations with key opinion leaders (KOL) who recognized early the potential for our pressure-based platforms and who went on to report their discoveries in peer reviewed journals. Among the KOLs working with us is Dr. Ruedi Aebersold (Head of the Department of Biology, ETH, Zurich). Dr. Aebersold, a pioneer in proteomics, worked with our scientists and engineers to develop PCT-SWATH (aka PCT-HD), a superior method for the extraction and preparation of proteins from samples intended for analysis by mass spectrometry. Other KOLs include Dr. Jennifer van Eyk (Director of Advanced Clinical Biosystems Institute in the Department of Biomedical Sciences, Cedar Sinai, Los Angeles, CA) and Dr. Wayne Hubble (Jules Stein Professor at the University of California, LA). Dr. van Eyk is a recognized expert in the causes of heart disease and is using PCT in her attempt to discover cardiac disease biomarkers. Dr. Hubble, a member of the National Academy of Sciences, is a leader in the field of electron paramagnetic resonance (EPR). He uses PCT in his studies of protein-protein interactions, which are highly important in the discovery of drug targets and drug design. The publications and presentations of these and other world class scientists have been invaluable in gaining initial entry of PCT in several areas of research. In addition to publications by our numerous KOLs, there are also many additional peer reviewed publications from dozens of other scientists discussing the advantages of the PCT platform in bio-molecule sample preparation, as well as the advantages of our BaroFold technology and our UST platform. To this end, we do all we can to disseminate the work of these scientists in an effort to increase the exposure of PCT, BaroFold, and UST to the worldwide research community.

Broadcasting Our PCT, BaroFold and UST Platform Technologies and Products

In 2023, we plan to expand our Sales and Marketing team, in order to support these efforts.

c. Foreign Distribution Network

We have previously established distribution arrangements covering China, Poland, South Korea, Japan, and 24 countries in Western Europe.

On December 3, 2021, we entered into a two-year distribution agreement with Westlake Omics Biotechnology, Ltd, in Hangzhou, China with the belief that they were capable of rapidly expanding the market for Barocyclers in China.

In February 2016, we entered into a three-year distribution agreement with Bioanalytic of Poland, pursuant to which PBI granted Bioanalytic exclusive distribution rights to all of our PCT products in Poland... In August of 2021, we expanded our relationship with Bioanalytic to reflect an exclusive distribution relationship for all of the EU and non-EU members in Western Europe, in addition to Poland. In August 2021, we signed an exclusive distribution agreement with Bioanalytic on Aug 1 2021 that expires on December 31, 2023.

In September of 2016, we entered into a three-year distribution agreement with Vita Co. of Japan, pursuant to which we granted Vita Co. exclusive distribution rights to all of our PCT products in Japan. This agreement expired in 2019. We continue to maintain a distribution relationship with Vita and are in contract renewal discussions.

In January 2020, we entered into a three-year distribution agreement with SCINCO Co., LTD of South Korea, pursuant to which PBI granted SCINCO exclusive distribution rights to all of our PCT products in South Korea. The Companies are in discussion for an extension of this agreement.

Non-Exclusive and Other Distribution Agreements

In November 2011, we entered into a distributor agreement with OROBOROS Instruments Corp. (“OROBOROS”) of Austria, pursuant to which we granted OROBOROS non-exclusive world-wide distribution rights to our Shredder SG3 System and related products.

We are also the exclusive distributor, throughout the Americas, for Constant Systems, Ltd.’s (“CS”) cell disruption equipment, parts, and consumables. CS, a British company located northwest of London, England, has been providing niche biomedical equipment, related consumable products, and services to a global client base since 1989. CS designs, develops, and manufactures high pressure cell disruption equipment used by life sciences laboratories worldwide, particularly disruption systems for the extraction of proteins. The CS equipment provides a constant and controlled cell disruptive environment, giving the user superior, constant, and reproducible results whatever the application. CS has over 900 units installed in over 40 countries worldwide. The CS cell disruption equipment has proven performance in the extraction of cellular components, such as protein from yeast, bacteria, mammalian cells, and other sample types.

The CS pressure-based cell disruption equipment and our PCT-based instrumentation complement each other in several important ways. While both the CS and our technologies are based on high pressure, each product line has fundamental scientific capabilities that the other does not offer. Our PCT Platform uses certain patented pressure mechanisms to achieve small-scale, molecular level effects. CS’s technology uses different, proprietary pressure mechanisms for larger-scale, non-molecular level processing. In a number of routine laboratory applications, such as protein extraction, both effects can be critical to success. Therefore, for protein extraction and a number of other important scientific applications, we believe laboratories will benefit by using the CS and PBI products, either separately or together.

In June 2013, CS and PBI signed an expanded distribution agreement that made us the exclusive distributor of CS products throughout all of the Americas until the end of 2019. In October 2021, we renewed this distribution agreement for an additional two years.

d. Intellectual Property

We believe that protection of our intellectual property, through patents, trademarks and other trade secrets are essential to our business. Subject to the availability of sufficient financial resources, our practice is to file patent applications to protect technology, inventions, and improvements to inventions that are important to our business development. We also rely on trade secrets, know-how, and technological innovations to develop and maintain our potential competitive position.

The Company believes the UST method can find use in various nanoemulsion applications for effective delivery of desired oil-soluble components in pharmaceutical, nutraceutical, cosmeceutical, agrochemical, industrial and food/beverage (including shelf-stable “clean label”) products. We plan to design, develop, manufacture, and market three different models of BaroShear UST instruments:

Our issued patents expire between 2022 and 2030. Any failure to obtain and maintain adequate patent protection may adversely affect our ability to enter into, or affect the terms of, any arrangement for the marketing, sale or licensing of any of our products or technology platforms. It may also allow our competitors to duplicate our products without our permission and without compensation.

Summary of patents issued and pending for PBI:

License Agreements Relating to Pressure Cycling Technology

BioMolecular Assays, Inc.

In 1996, we acquired our initial equity interest in BioSeq, Inc., which at the time was developing our original pressure cycling technology. BioSeq, Inc. acquired its pressure cycling technology from BioMolecular Assays, Inc. under a technology transfer and patent assignment agreement. In 1998, we purchased all of the remaining outstanding capital stock of BioSeq, Inc., and at such time, the technology transfer and patent assignment agreement was amended to require us to pay BioMolecular Assays, Inc., a 5% royalty on our sales of products or services that incorporate or utilize the original pressure cycling technology that BioSeq, Inc. acquired from BioMolecular Assays, Inc. We were also required to pay BioMolecular Assays, Inc. 5% of the proceeds from any sale, transfer or license of all or any portion of the original pressure cycling technology. These payment obligations terminated March 7, 2016.

In connection with our acquisition of BioSeq, Inc., we licensed certain limited rights to the original pressure cycling technology back to BioMolecular Assays, Inc. This license is non-exclusive and limits the use of the original pressure cycling technology by BioMolecular Assays, Inc. solely for molecular applications in scientific research and development and in scientific plant research and development. BioMolecular Assays, Inc. is required to pay us a royalty equal to 20% of any license or other fees and royalties, but not including research support and similar payments, it receives in connection with any sale, assignment, license or other transfer of any rights granted to BioMolecular Assays, Inc. under the license. BioMolecular Assays, Inc. was required to pay us these royalties until the expiration in March 2016 of the patents held by BioSeq, Inc. since 1998. We have not received any royalty payments from BioMolecular Assays, Inc. under this license.

Battelle Memorial Institute

In December 2008, we entered into an exclusive patent license agreement with the Battelle Memorial Institute (“Battelle”). The licensed technology is the subject of a patent application filed by Battelle in 2008 and relates to a method and a system for improving the analysis of protein samples, including through an automated system utilizing pressure and a pre-selected agent to obtain a digested sample in a significantly shorter period than current methods, while maintaining the integrity of the sample throughout the preparatory process. In addition to royalty payments on net sales of “licensed products,” we are obligated to make minimum royalty payments for each year that we retain the rights outlined in the patent license agreement and we are required to have our first commercial sale of the licensed products within one year following the issuance of the patent covered by the licensed technology. After re-negotiating the terms of the contract in 2013, the minimum annual royalty was $1,200 in 2014 and $2,000 in 2015; the minimum royalties were $3,000 in 2016, $4,000 in 2017 and $5,000 in 2018 and each calendar year thereafter during the term of the agreement.

We have been successful in raising cash through debt and equity offerings in the past. We have efforts in place to continue to raise cash through debt and equity offerings.

Although we have successfully completed equity financings and reduced expenses in the past, we cannot assure our investors that our plans to address these matters in the future will be successful. Additional financing may not be available to us on a timely basis or on terms acceptable to us, if at all. In the event we are unable to raise sufficient funds on terms acceptable to us, we may be required to:

g. Regulation

Many of our activities are subject to regulation by governmental authorities within the United States and similar bodies outside of the United States. The regulatory authorities may govern the collection, testing, manufacturing, safety, efficacy, labeling, storage, record keeping, transportation, approval, advertising, and promotion of our products, as well as the training of our employees.

Currently, our PCT commercialization efforts are focused in the area of genomic, proteomic, lipidomic, and small molecule sample preparation. We do not believe that our current Barocycler products used in sample preparation are considered “medical devices” under the United States Food, Drug and Cosmetic Act (the “FDA Act”) and we do not believe that we are subject to the law’s general control provisions that include requirements for registration, listing of devices, quality regulations, labeling and prohibitions against misbranding and adulteration. We also do not believe that we are subject to regulatory inspection and scrutiny. If, however, we are successful in commercializing PCT in applications beyond our current focus area of genomic, proteomic, lipidomic, and small molecule sample preparation, such as protein purification, pathogen inactivation and immunodiagnostics, our products may be considered “medical devices” under the FDA Act, at which point we would be subject to the law’s general control provisions and regulation by the FDA that include requirements for registration listing of devices, quality regulations, labeling, and prohibitions against misbranding and adulteration. The process of obtaining approval to market these devices in the other potential applications of PCT would be costly and time consuming and could possibly prohibit us from pursuing such markets.

Some of our devices may also become subject to the European Pressure Equipment Directive, which requires certain pressure equipment meet certain quality and safety standards. We do not believe that we are currently subject to this directive because our Barocycler instruments are below the threshold documented in the text of the directive. If our interpretation were to be challenged, we could incur significant costs defending the challenge, and we could face production and selling delays, all of which could harm our business.

We self-certified that our Barocycler instrumentation was electromagnetically compatible, or “CE” compliant, which means that our Barocycler instruments meet the essential requirements of the relevant European health, safety and environmental protection legislation. In order to maintain our CE Marking, a requirement to sell equipment in many countries of the European Union, we are obligated to uphold certain safety and quality standards.

h. Employees

On December 31, 2022, we had 15 full-time employees 2 part-time employees and 1 intern. All employees enter into confidentiality agreements intended to protect our proprietary information. We believe that our relations with our employees are good. None of our employees are represented by a labor union. Our performance depends on our ability to attract and retain qualified professional, scientific and technical staff. The level of competition among employers for skilled personnel is high. Subject to our limited financial resources, we attempt to maintain employee benefit plans to enhance employee morale, professional commitment and work productivity and provide an incentive for employees to remain with us.

i. Corporate Information

We were incorporated in the Commonwealth of Massachusetts in August 1978 as Boston Biomedica, Inc. In 1996, Boston Biomedica completed a successful initial public offering and was listed on the NASDAQ market (where we maintained a listing until 2012). In September 2004, we completed the sale of Boston Biomedica’s core business units and began to focus exclusively on the development and commercialization of the PCT platform. Following this change in business strategy, we changed our legal name from Boston Biomedica, Inc. to Pressure BioSciences, Inc. We began operations as PBI in February 2005, research and development activities in April 2006, early marketing and selling activities of our Barocycler instruments in late 2007, and active marketing and selling of our PCT-based instrument platform in 2012. PBI maintained its listing on NASDAQ until 2012, at which time it was down-listed to the OTCQB market. PBI continues to focus on its objective of up-listing to a major exchange such as the NASDAQ or NYSE markets as soon as reasonably possible.

ITEM 1A. RISK FACTORS

This Annual Report on Form 10-K contains forward-looking statements that involve risks and uncertainties, such as statements of our objectives, expectations and intentions. The cautionary statements made in this Annual Report on Form 10-K should be read as applicable to all forward-looking statements wherever they appear in this report. Our actual results could differ materially from those discussed herein. Factors that could cause or contribute to such differences include those discussed below, as well as those discussed elsewhere in this Annual Report on Form 10-K.

Risks Related To Our COMPANY

We have received an opinion from our independent registered public accounting firm expressing substantial doubt regarding our ability to continue as a going concern.

The audit report issued by our independent registered public accounting firm on our audited consolidated financial statements for the fiscal year ended December 31, 2022, contains an explanatory paragraph regarding our ability to continue as a going concern. The audit report states that our auditing firm determined that there was substantial doubt in our ability to continue as a going concern due to the risk that we may not have sufficient cash and liquid assets at December 31, 2022 to cover our operating and capital requirements for the next twelve-month period; and if sufficient cash cannot be obtained, we would have to substantially alter, or possibly even discontinue, operations. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Management has developed a plan to continue operations. This plan includes continued control of expenses and obtaining equity or debt financing. Although we have successfully completed equity financings and reduced expenses in the past, we cannot assure you that our plans to address these matters in the future will be successful.

The factors described above could adversely affect our ability to obtain additional financing on favorable terms, if at all, and may cause investors to have reservations about our long-term prospects and may adversely affect our relationships with customers. There can be no assurance that our auditing firm will not issue the same opinion in the future. If we cannot successfully continue as a going concern, our stockholders may lose their entire investment.

Our revenue is dependent upon acceptance of our products by the market. The failure of such acceptance will cause us to curtail or cease operations.

Our revenue comes from the sale of our products. As a result, we will continue to incur operating losses until such time as sales of our products reach a mature level and we are able to generate sufficient revenue from the sale of our products to meet our operating expenses. There can be no assurance that customers will adopt our technology and products, or that businesses and prospective customers will agree to pay for our products. In the event that we are not able to significantly increase the number of customers that purchase our products, or if we are unable to charge the necessary prices, our financial condition and results of operations will be materially and adversely affected.

Our business could be adversely affected if we fail to implement and maintain effective disclosure controls and procedures and internal control over financial reporting.

We concluded that as of December 31, 2022, our disclosure controls and procedures and our internal control over financial reporting were not effective. We have determined that we have limited resources for adequate personnel to prepare and file reports under the Securities Exchange Act of 1934 within the required time periods and that material weaknesses in our internal control over financial reporting exist relating to our accounting for complex equity transactions. If we are unable to implement and maintain effective disclosure controls and procedures and remediate the material weaknesses in a timely manner, or if we identify other material weaknesses in the future, our ability to produce accurate and timely financial statements and public reports could be impaired, which could adversely affect our business and financial condition. We identified a lack of sufficient segregation of duties. Specifically, this material weakness is such that the design over these areas relies primarily on detective controls and could be strengthened by adding preventive controls to properly safeguard assets. In addition, investors may lose confidence in our reported information and the market price of our common stock may decline.

We have a history of operating losses, anticipate future losses and may never be profitable.

We have experienced significant operating losses in each period since we began investing resources in PCT and CP. These losses have resulted principally from research and development, sales and marketing, and general and administrative expenses associated with the development of our PCT business and more recently our BaroFold and UST business. During the year ended December 31, 2022, we recorded a net loss available to common shareholders of $17,803,953 or ($1.61) per share, as compared with $22,685,459 or ($3.42) per share, for the corresponding period in 2021. We expect to continue to incur operating losses until sales increase substantially. We cannot be certain when, if ever, we will become profitable. Even if we were to become profitable, we might not be able to sustain such profitability on a quarterly or annual basis.

If we are unable to obtain additional financing, business operations will be harmed and if we do obtain additional financing then existing shareholders may suffer substantial dilution.

We need substantial capital to implement our sales distribution strategy for our current products and to develop and commercialize future products using our high-pressure technology products and services across all of our targeted markets. Our capital requirements will depend on many factors, including but not limited to:

We expect the net proceeds from our financing plans, along with our current cash position, will enable us to fund our operating expenses and capital expenditure requirements for at least the next 24 months, during which time we expect to achieve profitability. If we do not achieve profitability as planned, we anticipate that we will need to raise additional capital to fund our operations and to otherwise implement our overall business strategy. We currently do not have any contracts or commitments for additional financing. There can be no assurance that financing will be available in amounts or on terms acceptable to us, if at all. Any additional equity financing may involve substantial dilution to then existing shareholders.

If adequate funds are not available or if we fail to obtain acceptable additional financing, we may be required to:

We have incurred substantial debt, which could impair our flexibility and access to capital and adversely affect our financial position, and our business would be materially adversely affected if we are unable to service our debt obligations.

As described in Note 9 to our audited financial statements, as of December 31, 2022, there were $17.8 million in convertible notes outstanding some of which is past due. One lender holds approximately $9.4 million of this debt. In addition, as of December 31, 2022 we were making daily payments of $11,670. As of March 31, 2023 we were making weekly payments totaling $60,157 to service Merchant Agreements.

We may incur additional indebtedness from time to time to implement our sales distribution strategy for our current products and to develop and commercialize future products using our high-pressure technology products and services across all of our targeted markets.

Our substantial indebtedness may:

In addition, our cash balance is significantly less than the principal amount of our outstanding debt, and we may not generate sufficient cash flow from our operations to pay our substantial debt. Any debt financing that is available could cause us to incur substantial costs and subject us to covenants that significantly restrict our ability to conduct our business.

Our financial results depend on revenues from our high-pressure technology products and services, and from government grants.

We currently rely on revenues from PCT, CP, BaroFold and UST technology products and services, and from revenues derived from grants awarded to us by governmental agencies, such as the National Institutes of Health. Through 2021, we have not yet achieved product readiness for BaroFold and UST, and/or market acceptance of our product offerings, to the extent necessary to achieve revenue growth sufficient to establish profitability. Competition for government grants is very intense, and we can provide no assurance that we will continue to be awarded grants in the future. If we are unable to increase revenues from sales of our high-pressure technology products and services and government grants, our business will fail.

We may be unable to obtain market acceptance of our high-pressure technology products and services.

Many of the initial sales of our pressure cycling technology products and services have been to our collaborators, following their use of our products in studies undertaken in sample preparation for genomics, proteomics, lipidomics, and small molecules studies. Later sales have been to key opinion leaders. Our technology requires scientists and researchers to adopt a method of sample extraction that is different from existing techniques. Our PCT sample preparation system is also more costly than most existing techniques. Our ability to obtain market acceptance will depend, in part, on our ability to demonstrate to our potential customers that the benefits and advantages of our technology outweigh the increased cost of our technology compared with existing methods of sample extraction. Similar early technology introduction, trial and acceptance challenges must be surmounted for the BaroFold and UST products and services, as well. If we are unable to demonstrate the benefits and advantages of our products and technology as compared with existing technologies, we will not gain market acceptance and our business will fail.

Our business may be harmed if we encounter problems, delays, expenses, and complications that often affect companies that have not achieved significant market acceptance.

Our high-pressure technology businesses will continue to face challenges in achieving market acceptance. If we encounter problems, delays, expenses and complications, many of which may be beyond our control or may harm our business or prospects. These include:

The sales cycle of our high-pressure technology products is lengthy. We have incurred and may continue to incur significant expenses and we may not generate any significant revenue related to those products.

Many of our current and potential customers have required between three and six months or more to test and evaluate our high-pressure technology products. This increases the possibility that a customer may decide to cancel its order or otherwise change its plans, which could reduce or eliminate our sales to that potential customer. As a result of this lengthy sales cycle, we have incurred and may continue to incur significant research and development, selling and marketing, and general and administrative expense related to customers from whom we have not yet generated any revenue from our products, and from whom we may never generate the anticipated revenue if a customer is not satisfied with the results of the evaluation of our products or if a customer cancels or changes its plans.

Our business could be harmed if our products contain undetected errors or defects.

We are continuously developing new and improving our existing, high-pressure technology products and we expect to do so across many areas of life sciences applications depending upon the availability of our resources. Newly introduced products can contain undetected errors or defects. In addition, these products may not meet their performance specifications under all conditions or for all applications. If, despite internal testing and testing by our collaborators, any of our products contain errors or defects or fail to meet customer specifications, then we may be required to enhance or improve those products or technologies. We may not be able to do so on a timely basis, if at all, and may only be able to do so at considerable expense. In addition, any significant reliability problems could result in adverse customer reaction, negative publicity or legal claims and could harm our business and prospects.

Our success may depend on our ability to manage growth effectively.

Our failure to manage growth effectively could harm our business and prospects. Given our limited resources and personnel, growth of our business could place significant strain on our management, information technology systems, sources of manufacturing capacity and other resources. To properly manage our growth, we may need to hire additional employees and identify new sources of manufacturing capabilities. Failure to effectively manage our growth could make it difficult to manufacture our products and fill orders, as well as lead to declines in product quality or increased costs, any of which would adversely impact our business and results of operations.

Our success is substantially dependent on the continued service of our senior management.

Our success is substantially dependent on the continued service of our senior management, specifically our Chief Executive Officer, Richard T. Schumacher. The loss of the services of any of our senior management could make it more difficult to successfully operate our business and achieve our business goals. In addition, our failure to retain existing engineering, research and development, operations, and marketing/sales personnel could harm our product development capabilities and customer and employee relationships, delay the growth of sales of our products, and result in the loss of key information, expertise, or know-how.

We may not be able to hire or retain the number of qualified personnel, particularly engineering and sales personnel, required for our business, which would harm the development and sales of our products and limit our ability to grow.

Competition in our industry for senior management, technical, sales, marketing, finance and other key personnel is intense. If we are unable to retain our existing personnel, or attract and train additional qualified personnel, either because of competition in our industry for such personnel or because of insufficient financial resources, our growth may be limited. Our success also depends in particular on our ability to identify, hire, train and retain qualified engineering and sales personnel with experience in design, development and sales of laboratory equipment.

Our reliance on a single third party for all of our manufacturing, and certain of our engineering, and other related services could harm our business.

We currently solely rely on CBM Industries, a third-party contract manufacturer, to manufacture our Barocycler 2320EXT instrumentation, provide manufacturing expertise, and manage the majority of our sub-contractor supplier relationships for this instrument. Because of our dependence on one manufacturer, our success will depend, in part, on the ability of CBM to manufacture our products cost effectively, in sufficient quantities to meet our customer demand, if and when such demand occurs, and meeting our quality requirements. If CBM experiences manufacturing problems or delays, or if CBM decides not to continue to provide us with these services, our business may be harmed. While we believe other contract manufacturers are available to address our manufacturing and engineering needs, if we find it necessary to replace CBM, there will be a disruption in our business and we would incur additional costs and delays that would harm our business.

Our failure to manage current or future alliances or joint ventures effectively may harm our business.

We have entered business relationships with four distribution partners and one co-marketing partner, and we may enter into additional alliances, joint ventures or other business relationships to further develop, market and sell our pressure cycling technology product line. We may not be able to:

Furthermore, any alliance, joint venture or other business relationship may divert management time and resources. Entering into a disadvantageous alliance, joint venture or business relationship, failing to manage an alliance, joint venture or business relationship effectively, or failing to comply with any obligations in connection therewith, could harm our business and prospects.

We may not be successful in growing our international sales.

We cannot guarantee that we will successfully develop our international sales channels to enable us to generate significant revenue from international sales. We currently have four international distribution agreements that cover 24 countries in Europe, Asia and Australia. We have generated limited sales to date from international sales and cannot guarantee that we will be able to increase our sales. As we expand, our international operations may be subject to numerous risks and challenges, including:

Our operating results are subject to quarterly variation. Our operating results may fluctuate significantly from period to period depending on a variety of factors, including but not limited to the following:

Our instrumentation operates at high pressures and may therefore become subject to certain regulations in the European Community. Regulation of high-pressure equipment may limit or hinder our development and sale of future instrumentation.

Our Barocycler instruments operate at high pressures. If our Barocycler instruments exceed certain pressure levels, our products may become subject to the European Pressure Equipment Directive, which requires certain pressure equipment meet certain quality and safety standards. We do not believe that we are subject to this directive because our Barocycler instruments are currently below the threshold documented in the text of the directive. If our interpretation were to be challenged, we could incur significant costs defending the challenge, and we could face production and selling delays, all of which could harm our business.

We expect that we will be subject to regulation in the United States, such as by the Food and Drug Administration, and overseas, if and when we begin to invest more resources in the development and commercialization of PCT in applications outside of sample preparation for the research field.

Our current pressure cycling technology products in sample preparation for the research field are not regulated by the FDA. Certain applications in which we intend to develop and commercialize pressure cycling technology, such as protein purification, pathogen inactivation and immunodiagnostics, are expected to require regulatory approvals or clearances from regulatory agencies, such as the FDA, prior to commercialization, when we expand our commercialization activities outside of the research field. We expect that obtaining these approvals or clearances will require a significant investment of time and capital resources and there can be no assurance that such investments will receive approvals or clearances that would allow us to commercialize the technology for these applications.

If we are unable to protect our patents and other proprietary technology relating to our pressure cycling technology products, our business will be harmed.

Our ability to further develop and successfully commercialize our products will depend, in part, on our ability to enforce our patents, preserve our trade secrets, and operate without infringing the proprietary rights of third parties. To date, we have been awarded 26 total United States and foreign patents related to our PCT technology platform, and one US patent and two additional patents in China related to our Ultra Shear Technology. We also received eight patents with our purchase of the assets of BaroFold in December 2017.

There can be no assurance that (a) any patent applications filed by us will result in issued patents; (b) patent protection will be secured for any particular technology; (c) any patents that have been or may be issued to us will be valid or enforceable; (d) any patents will provide meaningful protection to us; (e) others will not be able to design around our patents; and (f) our patents will provide a competitive advantage or have commercial value. The failure to obtain adequate patent protection would have a material adverse effect on us and may adversely affect our ability to enter into, or affect the terms of, any arrangement for the marketing or sale of any product.

Our patents may be challenged by others.

We could incur substantial costs in patent proceedings, including interference proceedings before the United States Patent and Trademark Office, and comparable proceedings before similar agencies in other countries, in connection with any claims that may arise in the future. These proceedings could result in adverse decisions about the patentability of our inventions and products, as well as about the enforceability, validity, or scope of protection afforded by the patents.

If we are unable to maintain the confidentiality of our trade secrets and proprietary knowledge, others may develop technology and products that could prevent the successful commercialization of our products.

We rely on trade secrets and other unpatented proprietary information in our product development activities. To the extent we rely on trade secrets and unpatented know-how to maintain our competitive technological position, there can be no assurance that others may not independently develop the same or similar technologies. We seek to protect our trade secrets and proprietary knowledge, in part, through confidentiality agreements with our employees, consultants, advisors and contractors. These agreements may not be sufficient to effectively prevent disclosure of our confidential information and may not provide us with an adequate remedy in the event of unauthorized disclosure of such information. If our employees, consultants, advisors, or contractors develop inventions or processes independently that may be applicable to our products, disputes may arise about ownership of proprietary rights to those inventions and processes. Such inventions and processes will not necessarily become our property but may remain the property of those persons or their employers. Protracted and costly litigation could be necessary to enforce and determine the scope of our proprietary rights. Failure to obtain or maintain trade secret protection, for any reason, could harm our business.

If we infringe on the intellectual property rights of others, our business may be harmed.

It is possible that the manufacture, use or sale of our pressure cycling technology products or services may infringe patent or other intellectual property rights of others. We may be unable to avoid infringement of the patent or other intellectual property rights of others and may be required to seek a license, defend an infringement action, or challenge the validity of the patents or other intellectual property rights in court. We may be unable to secure a license on terms and conditions acceptable to us, if at all. Also, we may not prevail in any patent or other intellectual property rights litigation. Patent or other intellectual property rights litigation is costly and time-consuming, and there can be no assurance that we will have sufficient resources to bring any possible litigation related to such infringement to a successful conclusion. If we do not obtain a license under such patents or other intellectual property rights, or if we are found liable for infringement, or if we are unsuccessful in having such patents declared invalid, we may be liable for significant monetary damages, may encounter significant delays in successfully commercializing and developing our pressure cycling technology products, or may be precluded from participating in the manufacture, use, or sale of our pressure cycling technology products or services requiring such licenses.

We may be unable to adequately respond to rapid changes in technology and the development of new industry standards.

The introduction of products and services embodying new technology and the emergence of new industry standards may render our existing pressure cycling technology products and related services obsolete and unmarketable if we are unable to adapt to change. We may be unable to allocate the funds necessary to improve our current products or introduce new products to address our customers’ needs and respond to technological change. In the event that other companies develop more technologically advanced products, our competitive position relative to such companies would be harmed.

We may not be able to compete successfully with others that are developing or have developed competitive technologies and products.

Several companies have developed, or are expected to develop, products that compete or will compete with our products. We compete with companies that have existing technologies for the extraction of nucleic acids, proteins and small molecules from cells and tissues, including but not limited to methods such as mortar and pestle, sonication, rotor-stator homogenization, French press, bead beating, freezer milling, enzymatic digestion, and chemical dissolution.

We are aware that there are additional companies pursuing new technologies with similar goals to the products developed or being developed by us. Some of the companies with which we now compete, or may compete in the future, have or may have more extensive research, marketing, and manufacturing capabilities, more experience in genomics and proteomics sample preparation, protein purification, pathogen inactivation, immunodiagnostics, and DNA sequencing and significantly greater technical, personnel and financial resources than we do, and may be better positioned to continue to improve their technology to compete in an evolving industry. To compete, we must be able to demonstrate to potential customers that our products provide improved performance and capabilities. Our failure to compete successfully could harm our business and prospects.

We will need to increase the size of our organization and may experience difficulties in managing growth.

We are a small company with a minimal number of employees. We expect to experience a period of expansion in headcount, facilities, infrastructure and overhead and anticipate that further expansion will be required to address potential growth and market opportunities. Future growth will impose significant added responsibilities on members of management, including the need to identify, recruit, maintain and integrate new managers. Our future financial performance and its ability to compete effectively will depend, in part, on its ability to manage any future growth effectively.

Provisions in our articles of organization and bylaws may discourage or frustrate stockholders’ attempts to remove or replace our current management.

Our articles of organization and bylaws contain provisions that may make it more difficult or discourage changes in our management that our stockholders may consider to be favorable. These provisions include:

These provisions could prevent or frustrate attempts to make changes in our management that our stockholders consider to be beneficial and could limit the price that our stockholders might receive in the future for shares of our common stock.

The costs of compliance with the reporting obligations of the Exchange Act, and with the requirements of the Sarbanes-Oxley Act of 2002 and the Dodd-Frank Wall Street Reform and Consumer Protection Act, may place a strain on our limited resources and our management’s attention may be diverted from other business concerns.

As a result of the regulatory requirements applicable to public companies, we incur legal, accounting, and other expenses that are significant in relation to the size of our Company including expenses related to complying with the Sarbanes-Oxley Act of 2002 and the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as rules subsequently implemented by the SEC and OTC Markets Group, Inc. These requirements have placed and will continue to place a strain on our systems and on our management and financial resources.

Certain of our net deferred tax assets could be substantially limited if we experience an ownership change as defined in the Internal Revenue Code.

Certain of our net operating losses (“NOLs”) give rise to net deferred tax assets. Our ability to utilize NOLs and to offset our future taxable income and/or to recover previously paid taxes would be limited if we were to undergo an “ownership change” within the meaning of Section 382 of the Internal Revenue Code (the “Code”). In general, an “ownership change” occurs whenever the percentage of the stock of a corporation owned by “5 percent shareholders,” within the meaning of Section 382 of the Code, increases by more than 50 percentage points over the lowest percentage of the stock of such corporation owned by such “5 percent shareholders” at any time over the preceding three years.

An ownership change under Section 382 of the Code would establish an annual limitation on the amount of NOLs we could utilize to offset our taxable income in any single taxable year to an amount equal to (i) the product of a specified rate, which is published by the U.S. Treasury, and the aggregate value of our outstanding stock plus; and (ii) the amount of unutilized limitation from prior years. The application of these limitations might prevent full utilization of the deferred tax assets attributable to our NOLs. We may have or will have experienced an ownership change as defined by Section 382 through the sale of equity and, therefore, we will consider whether the sale of equity units will result in limitations of our net operating losses under Section 382 when we start to generate taxable income. However, whether a change in ownership occurs in the future is largely outside of our control, and there can be no assurance that such a change will not occur.

We continue to face risks related to Novel Coronavirus (COVID-19) which could continue to significantly disrupt our research and development, operations, sales, and financial results.

Our business was adversely impacted by the effects of the Novel Coronavirus (COVID-19). In addition to global macroeconomic effects, the Novel Coronavirus (COVID-19) outbreak and any other related adverse public health developments could continue to cause disruption to our operations, research and development, and sales activities. Our third-party manufacturers, third-party distributors, and our customers have been and will be disrupted by worker absenteeism, quarantines and restrictions on employees’ ability to work, office and factory closures, disruptions to ports and other shipping infrastructure, border closures, or other travel or health-related restrictions. Depending on the magnitude of such effects on our activities or the operations of our third-party manufacturers and third-party distributors, the supply of our products will be delayed, which could adversely affect our business, operations and customer relationships. In addition, the Novel Coronavirus (COVID-19) or other disease outbreak will in the short-run and may over the longer term adversely affect the economies and financial markets of many countries, resulting in an economic downturn that will affect demand for our products and impact our operating results. There can be no assurance that any decrease in sales resulting from the Novel Coronavirus (COVID-19) will be offset by increased sales in subsequent periods. Although the magnitude of the impact of the Novel Coronavirus (COVID-19) outbreak on our business and operations remains uncertain, the continued spread of the Novel Coronavirus (COVID-19) or the occurrence of other epidemics and the imposition of related public health measures and travel and business restrictions will adversely impact our business, financial condition, operating results and cash flows. In addition, we have experienced and will experience disruptions to our business operations resulting from quarantines, self-isolations, or other movement and restrictions on the ability of our employees to perform their jobs that may impact our ability to develop and design our products in a timely manner or meet required milestones or customer commitments.

RISKS RELATED TO OWNERSHIP OF OUR SECURITIES

The holders of our Common Stock could suffer substantial dilution due to our corporate financing practices.

The holders of our common stock could suffer substantial dilution due to our corporate financing practices, which, in the past few years, have included private placements and a registered direct offering. As of December 31, 2022, there were 13,682,910 shares of common stock issued and outstanding. As of December 31, 2022 there were 300 shares of Series D Convertible Preferred Stock issued and outstanding and convertible into 25,000 shares of common stock, 80,570 shares of Series G Convertible Preferred Stock issued and outstanding convertible into 26,857 shares of common stock, 10,000 shares of Series H Convertible Preferred Stock issued and outstanding convertible into 33,334 shares of common stock, 21 shares of Series H2 Convertible Preferred Stock issued and outstanding convertible into 70,000 shares of common stock, 3,458 shares of Series J Convertible Preferred Stock issued and outstanding convertible into 115,267 shares of common stock, 6,880 shares of Series K Convertible Preferred Stock issued and outstanding convertible into 229,334 shares of common stock and 8,645 shares of Series AA Convertible Preferred Stock issued and outstanding convertible into 8,645,000 shares of common stock.

Further, in connection with private placement offerings and the Series D registered direct offering, we issued warrants to purchase common stock. In addition, as of December 31, 2021, we had issued notes and debentures convertible into common stock at $2.50 per common share and outstanding options and warrants to purchase an aggregate of 17,540,209 shares of common stock; and debt convertible into 5,232,118 shares of common stock.

If all of the outstanding shares of Series D Convertible Preferred Stock, Series G Convertible Preferred Stock, Series H Convertible Preferred Stock, Series H2 Convertible Preferred Stock, Series J Convertible Preferred Stock, Series K Convertible Preferred Stock and Series AA Convertible Preferred Stock were converted into shares of common stock and all outstanding options and warrants to purchase shares of common stock were exercised and all convertible notes and debentures were converted, each as of December 31, 2021, an additional 31,921,119 shares of common stock would be issued and outstanding, summing to a total dilution of 41,041,645 common shares.. This additional issuance of shares of common stock would cause immediate and substantial dilution to our existing stockholders and could cause a significant reduction in the market price of our common stock.

From time to time, we also may increase the number of shares available for issuance in connection with our equity compensation plan, we may adopt new equity compensation plans, and we may issue awards to our employees and others who provide services to us outside the terms of our equity compensation plans. Our board of directors may fix and determine the designations, rights, preferences or other variations of each class or series of preferred stock and may choose to issue some or all of such shares to provide additional financing in the future.

The issuance of any securities for acquisition, licensing or financing efforts, upon conversion of any preferred stock or exercise of warrants, pursuant to our equity compensation plans, or otherwise may result in a reduction of the book value and market price of the outstanding shares of our common stock. If we issue any such additional securities, such issuance will cause a reduction in the proportionate ownership and voting power of all current stockholders. Further, such issuance may result in a change in control of our Company.

Sales of a significant number of shares of our common stock in the public market or the perception of such possible sales, could depress the market price of our common stock.

Sales of a substantial number of shares of our common stock in the public markets, which include an offering of our preferred stock or common stock could depress the market price of our common stock and impair our ability to raise capital through the sale of additional equity or equity-related securities. We cannot predict the effect that future sales of our common stock or other equity-related securities would have on the market price of our common stock.

Our share price could be volatile and our trading volume may fluctuate substantially.

The price of common stock has been and may in the future continue to be extremely volatile. Many factors could have a significant impact on the future price of our shares of common stock, including:

A decline in the price of our shares of common stock could affect our ability to raise further working capital and adversely impact our ability to continue operations.

The relatively low price of our shares of common stock, and a decline in the price of our shares of common stock, could result in a reduction in the liquidity of our common stock and a reduction in our ability to raise capital. Because a significant portion of our operations has been and will continue to be financed through the sale of equity securities, a decline in the price of our shares of common stock could be especially detrimental to our liquidity and our operations. Such reductions and declines may force us to reallocate funds from other planned uses and may have a significant negative effect on our business plans and operations, including our ability to continue our current operations. If the price for our shares of common stock declines, it may be more difficult to raise additional capital. If we are unable to raise sufficient capital, and we are unable to generate funds from operations sufficient to meet our obligations, we will not have the resources to continue our operations.

The market price for our shares of common stock may also be affected by our ability to meet or exceed expectations of analysts or investors. Any failure to meet these expectations, even if minor, may have a material adverse effect on the market price of our shares of common stock.

Financial Industry Regulatory Authority (“FINRA”) sales practice requirements may also limit a stockholder’s ability to buy and sell our common stock.

FINRA has adopted rules that require that in recommending an investment to a customer, a broker-dealer must have reasonable grounds for believing that the investment is suitable for that customer. Prior to recommending speculative low-priced securities to their non-institutional customers, broker-dealers must make reasonable efforts to obtain information about the customer’s financial status, tax status, investment objectives and other information. Under interpretations of these rules, FINRA believes that there is a high probability that speculative low-priced securities will not be suitable for at least some customers. FINRA requirements make it more difficult for broker-dealers to recommend that their customers buy our common stock, which may limit your ability to buy and sell our common stock and have an adverse effect on the market for our shares.

Our Common Stock is subject to the “Penny Stock” rules of the SEC and the trading market in our securities is limited, which makes transactions in our stock cumbersome and may reduce the value of an investment in our stock.

The Securities and Exchange Commission has adopted Rule 15g-9 which establishes the definition of a “penny stock,” for the purposes relevant to us, as any equity security that has a market price of less than $5.00 per share or with an exercise price of less than $5.00 per share, subject to certain exceptions. For any transaction involving a penny stock, unless exempt, the rules require:

In order to approve a person’s account for transactions in penny stocks, the broker or dealer must:

The broker or dealer must also deliver, prior to any transaction in a penny stock, a disclosure schedule prescribed by the Commission relating to the penny stock market, which, in highlight form:

Generally, brokers may be less willing to execute transactions in securities subject to the “penny stock” rules. This may make it more difficult for investors to dispose of our common stock and cause a decline in the market value of our stock.

Disclosure also has to be made about the risks of investing in penny stocks in both public offerings and in secondary trading and about the commissions payable to both the broker-dealer and the registered representative, current quotations for the securities and the rights and remedies available to an investor in cases of fraud in penny stock transactions. Finally, monthly statements have to be sent disclosing recent price information for the penny stock held in the account and information on the limited market in penny stocks.

We have never declared or paid a cash dividend on our common stock and we do not expect to pay cash dividends on our common stock in the foreseeable future.

Our shares of Series D Convertible Preferred Stock are entitled to certain rights, privileges and preferences over our common stock, including a preference upon a liquidation of our Company, which will reduce amounts available for distribution to the holders of our common stock.

The holders of our shares of Series D are entitled to payment, prior to payment to the holders of common stock in the event of liquidation of the Company. If we are dissolved, liquidated or wound up at a time when the Series D Preferred Stock remain outstanding, the holders of the Series D Preferred Stock will be entitled to receive only an amount equal to the liquidation preference (as it may be adjusted from time to time), plus any accumulated and unpaid dividends, to the extent that we have funds legally available. Any remaining assets will be distributable to holders of our other equity securities.

Shares eligible for future sale may adversely affect the market.

From time to time, certain of our stockholders may be eligible to sell all or some of their shares of common stock by means of ordinary brokerage transactions in the open market pursuant to Rule 144 promulgated under the Securities Act, subject to certain limitations. In general, pursuant to amended Rule 144, non-affiliate stockholders may sell freely after six months subject only to the current public information requirement. Affiliates may sell after six months subject to the Rule 144 volume, manner of sale (for equity securities), current public information and notice requirements. Any substantial sales of our common stock pursuant to Rule 144 may have a material adverse effect on the market price of our common stock.

We currently do not intend to pay dividends on our common stock. As result, your only opportunity to achieve a return on your investment is if the price of our common stock appreciates.

We currently do not expect to declare or pay dividends on our common stock. In addition, in the future we may enter into agreements that prohibit or restrict our ability to declare or pay dividends on our common stock. As a result, your only opportunity to achieve a return on your investment will be if the market price of our common stock appreciates and you sell your shares at a profit.

We could issue additional common stock, which might dilute the book value of our Common Stock.

Our Board of Directors has authority, without action or vote of our shareholders, to issue all or a part of our authorized but unissued shares. Such stock issuances could be made at a price that reflects a discount or a premium from the then-current trading price of our common stock. In addition, in order to raise capital, we may need to issue securities that are convertible into or exchangeable for our common stock. These issuances would dilute the percentage ownership interest, which would have the effect of reducing your influence on matters on which our shareholders vote and might dilute the book value of our common stock. Shareholders may incur additional dilution if holders of stock warrants or options, whether currently outstanding or subsequently granted, exercise their options, or if warrant holders exercise their warrants to purchase shares of our common stock.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION.

OVERVIEW

We are a leader in the development & sale of innovative, broadly enabling, pressure-based platform solutions for the worldwide life sciences industry. Our solutions 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 safely and reproducibly control bio-molecular interactions (e.g., cell lysis, biomolecule extraction). Historically, our primary focus has been in 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. In more recent years, 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 platform) 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.

On February 8, 2021, PBI announced plans to acquire the assets of a global eco-friendly agrochemical supplier. This opportunity is attractive as it has the potential of readily producing significant revenue, as well as the potential to apply the UST technology to improve some of the product line. In July 2021, a newly-formed subsidiary of PBI, PBI Agrochem, leased a warehouse in Sparks, NV, and hired a warehouse manager. See the further description of this possible transaction in Item 1 – Business – “The PBI Agrochem Platform.”

Patents

To date, we have been awarded 26 total United States and foreign patents related to our PCT technology platform, and one US patent and two additional patents in China related to our Ultra Shear Technology. We also received eight patents with our purchase of the assets of BaroFold in December 2017. PBI also has 19 pending patents in the USA, Canada, Europe, Australia, China, and Taiwan.

Primary Fields of Use and Application for PCT

Sample preparation is widely regarded as a significant impediment to research and discovery and sample extraction is generally regarded as one of the key parts of sample preparation. The process of preparing samples for genomic, proteomic, lipidomic, and small molecule studies includes a crucial step called sample extraction or sample disruption. This is the process of extracting biomolecules such as nucleic acid i.e., DNA and/or RNA, proteins, lipids, or small molecules from the plant or animal cells and tissues that are being studied. Our current commercialization efforts are based upon our belief that pressure cycling technology provides a superior solution for sample extraction when compared to other available technologies or procedures and thus might significantly improve the quality of sample preparation, and thus the quality of the test result.

Within the broad field of biological sample preparation, in particular sample extraction, we focus the majority of our PCT and constant pressure (“CP”) product development efforts in three specific areas: biomarker discovery (primarily through mass spectrometric analysis), forensics, and histology. We believe that our existing PCT and CP-based instrumentation and related consumable products fill an important and growing need in the sample preparation market for the safe, rapid, versatile, reproducible and quality extraction of nucleic acids, proteins, lipids, and small molecules from a wide variety of plant, animal, and microbiological cells and tissues.

Biomarker Discovery and Precision Medicine

The most commonly used technique worldwide for the preservation of cancer and other tissues for long-term storage and subsequent pathology evaluation is to process them into formalin-fixed, paraffin-embedded (“FFPE”) samples. We believe that the quality and analysis of FFPE tissues is highly problematic, and that PCT offers significant advantages over current processing methods, including standardization, speed, biomolecule recovery, and safety.

Our customers include researchers at academic laboratories, government agencies, biotechnology companies, pharmaceutical companies and other life science institutions in the Americas, Europe, Asia, Africa and Australia/Pacific. Our goal is to continue aggressive market penetration in these target areas. We also believe that there is a significant opportunity to sell and/or lease additional Barocycler instrumentation to additional laboratories within current customer organizations.

If we are successful in commercializing PCT in applications beyond our current focus area of genomic, proteomic, lipidomic, and small molecule sample preparation, and if we are successful in our attempts to attract additional capital, our potential customer base could expand to include hospitals, reference laboratories, pharmaceutical manufacturing plants and other sites involved in each specific application. If we are successful in forensics, our potential customers could be forensic laboratories, military and other government agencies. If we are successful in biomarker discovery and precision medicine - specifically the extraction of biomolecules from FFPE tissues, our potential customers could be pharmaceutical companies, hospitals, and laboratories focused on drug discovery or differentiation of disease states, subtypes and susceptibility to alternative treatments.

Forensics

The detection of DNA has become a part of the analysis of forensic samples by laboratories and criminal justice agencies worldwide in their efforts to identify the perpetrators of violent crimes and missing persons. Scientists from the University of North Texas and Florida International University have reported improvements in DNA yield from forensic samples (e.g., bone and hair) when using the PCT platform in the sample preparation process. We believe that PCT may be capable of differentially extracting DNA from sperm cells and female epithelial cells captured in swabs collected from rape victims and subsequently stored in rape kits. We also believe that there are many completed rape kits that remain untested for reasons such as cost, time and quality of results. We further believe that the ability to differentially extract DNA from sperm and not epithelial cells could reduce the cost of such testing, while increasing the quality, safety and speed of the testing process.

Going Concern

The audit report issued by our independent registered public accounting firm on our audited consolidated financial statements for the fiscal year ended December 31, 2022, contains an explanatory paragraph regarding our ability to continue as a going concern. The audit report states that our auditing firm determined that there was substantial doubt in our ability to continue as a going concern due to the risk that we may not have sufficient cash and liquid assets at December 31, 2022 to cover our operating and capital requirements for the next twelve-month period; and if sufficient cash cannot be obtained, we would have to substantially alter, or possibly even discontinue, operations. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Management has developed a plan to continue operations. This plan includes continued control of expenses and obtaining equity or debt financing. Although we have successfully completed equity financings and reduced expenses in the past, we cannot assure you that our plans to address these matters in the future will be successful.

The factors described above could adversely affect our ability to obtain additional financing on favorable terms, if at all, and may cause investors to have reservations about our long-term prospects and may adversely affect our relationships with customers. There can be no assurance that our auditing firm will not issue the same opinion in the future. If we cannot successfully continue as a going concern, our stockholders may lose their entire investment.

RESULTS OF OPERATIONS

Year Ended December 31, 2022 as compared with December 31, 2021

Products and Services Revenue

Revenue from the sale of products and services was $1,729,343 in the year ended December 31, 2022 compared with $2,002,365 in the year ended December 31, 2021, a 13.6 % decrease. Revenue included sales of both PBI and Constant System pressure-based products, sales of BaroFold and UST Contract Services and sales of PBI Agrochem products. Sales of instrumentation decreased in 2022 by $323,247 or 31%, from $1,046,845 in 2021 to $723,598 in 2022. Sales of consumables were $257,325 for the year ended December 31, 2022 compared to $274,108 for the same period in 2021, a decrease of $16,783 or 6%. Sales of BaroFold and UST Contract Services decreased by 27% from $268,157 in 2021 to $196,000 in 2022. Products, Services, and Other Revenue included $79,901 from non-cash transactions in the current year while the prior year included non-cash transactions of $11,046. Revenue from non-cash transactions was recognized based on the carrying value of the assets involved per ASC 845.

Cost of Products and Services

The cost of products and services was $2,014,004 for the year ended December 31, 2022, compared with $942,383 in 2021. Our cost of products and services increased $1,071,621 for the year ended December 31, 2022 compared to the year ended December 31, 2021. This increase was mostly attributed to an increase of our inventory reserve of $641,815 along with the full year expense of the warehouse space in Sparks NV to house the Agrochem products and the staff and associated expenses for its management.

Research and Development

Research and development expenses were $969,532 for 2022 compared to $1,101,509 in 2021, a decrease of $131,977 or 12%. The decrease was mostly due to the termination of one full time equivalent employee (“FTE”) at the end of 2021.

Selling and Marketing

Selling and marketing expenses were $401,444 in 2022 compared to $324,728 in 2021, an increase of $76,716, or 24%. The reported increase was attributable to the addition of one marketing FTE in mid-2022 and an increase in travel expenses due to now allowable customer visits and trade shows.

General and Administrative

General and administrative costs were $3,242,652 in the year ended December 31, 2022, as compared with $3,818,892 in 2021, a decrease of $576,240 or 15%. The reported decrease was attributable to a decrease in investor relation contracts costs and the cost of issuable shares associated with these contracts.

Operating Loss

Our operating loss was $4,898,289 for the year ended December 31, 2022 as compared to $4,185,147 for the prior year, an increase of $713,142 or 17%. This increase in operating loss was largely attributable to the increase of our inventory reserve of $641,815 and decreases in revenue and gross margin in 2022.

Interest Expense

Interest expense totaled $10,438,565 for the year ended December 31, 2022 as compared to interest expense of $14,450,241 for the year ended December 31, 2021. The decrease in interest expense in the year ended December 31, 2022, compared to the corresponding prior period, is attributable to a reduction of common stock and warrants issued for interest and less accretion of interest and amortization of debt discounts.

Unrealized gain and loss on investment in equity securities

Unrealized gain on investments in equity securities was $3,662 for the year ended December 31, 2022 compared to an unrealized loss of $457,025 for the year ended December 31, 2021. The reported increase was attributable to the increase in the market price of the Company’s investment in Nexity. As of December 31, 2022, we held 100,250 shares of common stock of Nexity Global SA, (a Polish publicly traded company).

Loss on extinguishment of liabilities

In connection with payments of interest in common stock and debt extensions, we calculated net losses on extinguishment of liabilities of $751,335 in the year ended December 31, 2022 and net losses of $1,061,073 in the year ended December 31, 2021. The decrease is attributable to a reduction of common stock and warrants issued for interest.

For the year ended December 31, 2021, we recognized a gain of $734,077 for the forgiveness of our two PPP loans by the U.S. which reduced our loss recorded for the year ended December 31, 2021.

Net Loss attributable to common stockholders

During the year ended December 31, 2022, we recorded a net loss attributable to common shareholders of $17,803,953 or ($1.61) per share, as compared with a net loss available to common shareholders of $22,685,459 or ($3.42) per share during the year ended December 31, 2021. This decrease in the loss per share is principally attributable to the 67% increase in weighted average shares outstanding in the year ended December 31, 2022 along with a smaller loss for 2022 as explained above.

LIQUIDITY AND FINANCIAL CONDITION

As of December 31, 2022, we did not have adequate working capital resources to satisfy our current liabilities. We have been successful in raising cash through debt and equity offerings in the past. We have efforts in place to continue to raise cash through debt and equity offerings.

We believe our current and projected capital raising plans, and our projected continued increases in revenue, will enable us to extend our cash resources for the foreseeable future. Although we have successfully completed equity and debt financings and reduced expenses in the past, we cannot assure you that our plans to address these matters in the future will be successful.

We believe we will need approximately $12 million in additional capital to fund our three-pronged operational plan, which was designed to help increase revenues and reach profitability, by:

However, if we are unable to obtain such funds through sales, the capital markets or other source of financing on acceptable terms, or at all, we will likely be required to cease our operations, pursue a plan to sell our operating assets, or otherwise modify our business strategy, which could materially harm our future business prospects. These conditions raise substantive doubt about our ability to continue as a going concern.

Net cash used in operating activities was $4,478,041 for the year ended December 31, 2022 as compared with $4,868,573 for the year ended December 31, 2021.

Net cash used in investing activities for the year ended December 31, 2022 totaled $20,755 compared to $122,945 for the year ended December 31, 2021.

Net cash provided by financing activities for the year ended December 31, 2022 was $4,370,350 as compared with $5,105,289 for the year ended December 31, 2021.

Our common stock is currently traded on the OTCQB tier of the OTC Markets under the trading symbol “PBIO.”

COMMITMENTS AND CONTINGENCIES

Battelle Memorial Institute

In December 2008, we entered into an exclusive patent license agreement with the Battelle Memorial Institute (“Battelle”). The licensed technology is described in the patent application filed by Battelle on July 31, 2008 (US serial number 12/183,219). This application includes subject matter related to a method and a system for improving the analysis of protein samples including, through an automated system, utilizing pressure and a pre-selected agent to obtain a digested sample in a significantly shorter period of time than current methods, while maintaining the integrity of the sample throughout the preparatory process. Pursuant to the terms of the agreement, we paid Battelle a non-refundable initial fee of $35,000. In addition to royalty payments on net sales on “licensed products,” we are obligated to make minimum royalty payments for each year we retain the rights outlined in the patent license agreement; and, we are required to have our first commercial sale of the licensed products within one year following the issuance of the patent covered by the licensed technology. After re-negotiating the terms of the contract in 2013, the minimum annual royalty was $1,200 in 2014 and $2,000 in 2015; the minimum royalties were $3,000 in 2016, $4,000 in 2017 and $5,000 in 2018 and each calendar year thereafter during the term of the agreement.

Target Discovery Inc.

In March 2010, we signed a strategic product licensing, manufacturing, co-marketing, and collaborative research and development agreement with Target Discovery Inc. (“TDI”), a related party. Under the terms of the agreement, we have been licensed by TDI to manufacture and sell a highly innovative line of chemicals used in the preparation of tissues for scientific analysis (“TDI reagents”). The TDI reagents were designed for use in combination with our pressure cycling technology. The companies believe that the combination of PCT and the TDI reagents can fill an existing need in life science research for an automated method for rapid extraction and recovery of intact, functional proteins associated with cell membranes in tissue samples. We did not incur any royalty obligation under this agreement in 2022 or 2021.

In April 2012, we signed a non-exclusive license agreement with TDI to grant the non-exclusive use of our pressure cycling technology. We executed an amendment to this agreement on October 1, 2016 wherein we agreed to pay a monthly fee of $1,400 for the use of a lab bench, shared space and other utilities, and $2,000 per day for technical support services as needed. The agreement requires TDI to pay the Company a minimum royalty fee of $60,000 in 2022 and $60,000 in 2021. For the years ended December 31, 2022 and 2021, we reported expenses of $69,300 and $82,800, respectively for these arrangements.

Severance and Change of Control Agreements

Each of Mr. Schumacher, Dr. Ting, and Dr. Lazarev, executive officers of the Company, are entitled to receive a severance payment if terminated by us without cause. The severance benefits would include a payment in an amount equal to one year of such executive officer’s annualized base salary compensation plus accrued paid time off. Additionally, the officer will be entitled to receive medical and dental insurance coverage for one year following the date of termination.

Pursuant to severance agreements with each of Mr. Schumacher, Dr. Ting, and Dr. Lazarev, each such executive officer is entitled to receive a change of control payment in an amount equal to one year (other than Mr. Schumacher) of such executive officer’s annualized base salary compensation, accrued paid time off, and medical and dental coverage, in the event the officer is terminated as a result of a change of control of our Company. In the case of Mr. Schumacher, his payment is equal to two years of annualized base salary compensation, accrued paid time off, and two years of medical and dental coverage.

Pursuant to our equity incentive plans, any unvested stock options held by a named executive officer will become fully vested upon a change in control (as defined in the 2005 Equity Incentive Plan) of our Company.

Lease Commitments

We lease building space under non-cancelable leases in South Easton, MA, and lab space in Medford, MA and warehouse space in Sparks, NV. Rental costs are expensed as incurred. During 2022 and 2021 we incurred $243,250 and $203,367, respectively, in rent expense for the use of our corporate office, warehouse and research and development facilities.

Following is a schedule by year of future minimum rental payments required under operating leases with initial or remaining non-cancelable lease terms in excess of one year as of December 31, 2022:

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of December 31, 2022 and December 31, 2021.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates, assumptions and judgments that affect the amounts reported in the financial statements, including the notes thereto. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates. We do not consider any of our policies or estimates to be critical. Refer to Note 3 – Summary of Significant Accounting Policies to our financial statements for a complete discussion of the significant accounting policies and methods used in the preparation of our financial statements.

Management believes its application of accounting policies, and the estimates inherently required therein, are reasonable. These accounting policies and estimates are periodically reevaluated, and adjustments are made when facts and circumstances dictate a change.

Recent Accounting Standards

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. The Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption.

In August 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, as part of its overall simplification initiative to reduce costs and complexity of applying accounting standards while maintaining or improving the usefulness of the information provided to users of financial statements. Among other changes, the new guidance removes the beneficial conversion separation model for convertible debt. As a result, after adopting the guidance, entities will no longer account for beneficial conversion features in equity. The guidance is effective for public business entities, other than small reporting company’s financial statements starting January 1, 2022, with early adoption permitted. The Company is a small reporting company and early adopted the new guidance on January 1, 2022 using the modified retrospective approach and recorded a cumulative effect of adoption equal to a $2,728,243 decrease in additional paid in capital and a $2,255,216 decrease in accumulated deficit. There is no material impact to the Company’s statements of operations or cash flows as the result of the adoption of ASU 2020-06.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Securities Exchange Act of 1934 filings are recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our President and Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, as ours are designed to do, and management was necessarily required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As of December 31, 2022, we carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were not effective as of December 31, 2022 due to limited resources for adequate personnel to prepare and file reports under the Securities Exchange Act of 1934 within the required periods, and material weaknesses in our internal control over financial reporting relating to our accounting for complex equity transactions as described below under the heading “Report of Management on Internal Control over Financial Reporting”. Management plans to remediate this weakness by taking the actions described below.

Report of Management on Internal Control over Financial Reporting

We are responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act, as a process designed by, or under the supervision of our principal executive and principal financial officers and effected by our board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:
