Overview
We are a leading commercial cell engineering company focused on providing enabling platform technologies to advance the discovery, development and commercialization of next-generation cell therapeutics and to support innovative cell-based research and development. Over more than two decades, we have developed and commercialized our proprietary Flow Electroporation ® platform, which facilitates complex engineering of a wide variety of cells.
Electroporation is a method of transfection, or the process of deliberately introducing molecules into cells, that involves applying an electric field in order to temporarily increase the permeability of the cell membrane. This precisely controlled increase in permeability allows the intracellular delivery of molecules, such as genetic material and proteins, that would not normally be able to cross the cell membrane as easily.
With increased knowledge of cell complexity and systems biology in the scientific community, researchers have sought to leverage or repurpose cell functions and/or machinery for research or therapeutic purposes. The ability to engineer living cells by introducing foreign molecules, such as gene editing systems and transgenes, has led to a revolution in biological research and resulted in numerous biological discoveries. Living human cells can also be engineered ex vivo , or outside the body, where they are repaired or reprogrammed to fight disease. In this case, the engineered cell itself is the drug.
Cell therapy has emerged as one of the fastest growing and most promising treatment modalities to address a host of human diseases. The recent success of multiple U.S. Food and Drug Administration (the “ FDA”) approved cell therapies providing long-lasting amelioration of symptoms or presence of disease has catalyzed tremendous investment—leading to exponential growth in cell-based therapies being evaluated for therapeutic applications. The Alliance for Regenerative Medicine (“ARM”), an international advocacy organization, estimates that the regenerative medicine sector, which consists of gene, cell, and tissue-based therapeutic developers raised an aggregate of $12.6 billion in 2022 and that, as of January 2023, there were more than 2,220 active clinical trials focused on regenerative and advanced medicine, which includes gene therapy, cell-based immuno-oncology, cell therapy and tissue engineering.
Our ExPERT platform, which is based on our Flow Electroporation technology, has been designed to address this rapidly expanding cell therapy market and can be utilized across the continuum of the high-growth cell therapy sector, from discovery and development through commercialization of next-generation, cell-based medicines. The ExPERT family of products includes four instruments, which we call the ATx™, STx™, GTx™ and VLx™, as well as a portfolio of proprietary related disposables and consumables. We launched the ExPERT VLx™ instrument for very large-scale cell engineering in September 2022. Our disposables and consumables include PAs designed for use with our instruments, as well as accessories supporting PAs such as electroporation buffer solution and software protocols. We have garnered meaningful expertise in cell engineering via our internal research and development efforts as well as our customer-focused commercial approach, which includes a growing application scientist team. The platform is also supported by a robust intellectual property portfolio with more than 150 granted U.S. and foreign patents and more than 95 pending patent applications worldwide.
From leading commercial cell therapy drug developers and top biopharmaceutical companies to top academic and government research institutions, including the U.S. National Institutes of Health (“NIH”), our customers have extensively validated our technology. We believe the features and performance of our platform have led to sustained customer engagement. Our existing customer base ranges from large biopharmaceutical companies, including all of the top 10, and 20 of the top 25, pharmaceutical companies based on 2021 global revenue, to hundreds of biotechnology companies and academic centers focused on translational research.

Our Competitive Strengths
We believe our industry leadership position and continued growth will be driven by the following competitive strengths:
• Proprietary technology platform that unlocks the significant potential of cell-based therapeutics . We built our ExPERT platform to advance the growing demands for non-viral delivery and next-generation cell and gene engineering approaches. Our ExPERT platform enables delivery of almost any molecule into almost any cell type. We believe our ExPERT platform leads the industry in performance, as measured by consistency, efficiency, viability, flexibility and scale. Our ExPERT platform is further supported by a robust intellectual property portfolio.
• Comprehensive, high-performance transfection platform . We believe our ExPERT platform offers a unique value proposition given the flexibility to scale up from research to current good manufacturing practices (“cGMP”) manufacturing on a single platform— enabling the engineering of cells ranging from tens of thousands of cells to more than tens of billions of cells in a single transfection run taking 30 minutes or less. Our long-term internal engineering expertise is supplemented by our customer focused approach—with a growing application scientist team working with our customers across increasingly diverse applications.
• Recognition as a leader in the large and growing next-generation cell therapy market with the ability to capitalize on rising demand for non-viral approaches. We believe we are well positioned to increase our market share within the large and growing next-generation cell therapy market. Since the FDA approved the first engineered CAR-T cell therapies to treat blood-based cancers in 2017, the number of cell therapy candidates being evaluated pre-clinically and clinically has grown exponentially. We expect growth to continue given the remaining high unmet medical need in cancer and other chronic conditions and predict increased investments in cell therapy product development across a variety of human diseases. We expect to grow our market share given the high performance of our platform and the ongoing adoption of non-viral delivery as the industry has trended towards developing advanced cell-based therapies with complex engineering strategies to improve efficacy, reduce time to patient treatment and expand into new indications.
• Innovative partnership business model focused on value creation and shared success . Our SPL partnerships allow us to participate in the value creation of our customers’ programs via precommercial milestones and in nearly all cases commercial sales-based payments. We intend to continue to build a portfolio of strategic partnerships with cell therapy developers, which provide us with a growing, diversified source of annual licenses and potential downstream revenue.
In addition to the high performance and flexibility of the ExPERT platform, we believe our partnership model further reduces clinical risk and development timelines for our cell therapy partners. By entering into SPL partnerships with us, for example, our partners gain access to our FDA Master File to support their IND-enabling studies and potentially shorten clinical development. Our FDA Master File, which is a submission to the FDA with confidential detailed information about our products, methods, processes and data, was originally established in 2002 and has been continuously updated as platform improvements are implemented to support different applications and cell types. The FDA Master File and equivalent Technical Files in other countries can be referenced by our partners to support their own regulatory submissions with the goal of accelerating regulatory submissions processes for our partners. To date, our FDA Master File and Technical Files have been referenced by our customers in over 40 clinical trials.

• Recurring revenue model provides high visibility, with drivers of potential long-term upside. Our business model enables us to generate substantial revenue from five sources: sales of instruments, disposables and consumables to new customers; additional sales of instruments, disposables and consumables to our existing installed base; annual instrument license fees from cell therapy customers; potential precommercial milestones under SPL partnerships; and potential commercial sales-based payments under SPL partnerships. We generate recurring revenue from our ExPERT instrumentation licenses, as well as disposables and consumables (or buffer) sales, which provides high visibility into future near-term revenue. In addition to recurring revenue, we have the potential to receive meaningful precommercial and commercial payments under SPL partnerships as our customers achieve success in advancing programs through the clinic and into the commercial stage. In aggregate, given our SPLs entered into to-date, we have the potential to receive over $1.55 billion in precommercial milestone payments, if all of the programs were to be granted regulatory approvals.
• Leadership team and workforce with deep domain knowledge. Our management team combines strong and broad subject matter expertise with a demonstrated history of commercial and operational execution. Moreover, our workforce has deep domain knowledge across a range of scientific, engineering, regulatory and business disciplines. We have supplemented our diverse technical experience by assembling a deep operational team with expertise in manufacturing, legal, sales, marketing, customer service and finance. We believe the team we have assembled with talent from multiple disciplines and a science- and customer-focused culture represents a significant competitive advantage for us. As of December 31, 2022, of our 125 full-time employees, 68 have advanced degrees including 25 with Ph.D. degrees.
Our Technology Platform
The foundation of our technology is our proprietary and patented Flow Electroporation platform, which we have developed and optimized for more than 20 years. Electroporation, or electro-permeabilization, leverages the fundamental properties of cell membranes, the ability to create reversible permeability in the presence of an electric charge, as a universal method to introduce foreign molecules, or transfect, eukaryotic cells, which are cells with a cell membrane and nucleus. Electroporation can be applied to almost any eukaryotic cell type to deliver a broad range of molecules, including DNA, human messenger RNA (“mRNA”), siRNA and proteins. Our proprietary Flow Electroporation platform is fully scalable and can support small-scale research and development through large-scale cell engineering for development of commercial therapeutics.
Our technology platform is marketed under the ExPERT brand, the elements of which are depicted in the graphic above. The value of our ExPERT brand starts with Efficiency—with high delivery Efficiency , users can achieve Potency , with high Potency, users improve their chances of therapeutic Efficacy , and if this can be repeated, Reproducibly from patient to patient, users have a successful Therapy . By delivering high efficiency at any scale, the ExPERT platform is designed to improve our customer’s ability to achieve the required therapeutic index, enabling accelerated, cost-efficient translation of complex cellular therapies from research to the clinic.
Our ExPERT platform consists of four instruments, the ATx, STx, GTx and VLx, which use a broad range of PAs, or disposables, of different volumes to enable scalable electroporation from tens of thousands to billions of cells to facilitate the translation of complex cellular therapies from concept to the clinic, in support of the intended therapeutic

Overview of our ExPERT Platform
Our Flow Electroporation Technology was designed to meet the stringent demands of clinical use— namely, the ability to safely and reproducibly modify a broad range of primary human cells with high efficiency, low cytotoxicity, and at the scale required to enable the treatment of patients across a diverse range of diseases.
We believe the current ExPERT instrument family represents the next generation of our clinically validated, electroporation technology for complex and scalable cellular engineering. By delivering high transfection efficiency with enhanced functionality and ease of use, the ExPERT platform delivers the high-end performance that we believe is essential to enabling the next wave of biological and cellular therapeutics. The combination of the ExPERT instruments, associated disposables and universal electroporation buffer provides researchers, production scientists, and cGMP facilities with a solution to transfect cells with high efficiency, viability and consistency, which are the three attributes that are consistently ranked by our customers as the top requirements when choosing a cellular or gene engineering platform for clinical use. We believe our ExPERT platform is seen as a critical enabling technology by many of the leading cell therapy companies, helping them to achieve their program goals and milestones expeditiously. Our instruments are sold or licensed for research or clinical use, while the associated disposables and electroporation buffer are sold to support pre-clinical research and development work and are compatible for integration into cGMP manufacturing environments.
We believe that the following four components of our platform have allowed us to successfully address the increasing complexity of cellular engineering approaches in the industry:
• instrument design;
• electroporation and cell handling protocols;
• PAs (disposables); and
• universal electroporation buffer formulation (consumables).
In addition, we have implemented a global scientific and regulatory support strategy for our customers that is designed to accelerate clinical development and streamline the regulatory submission process, thereby potentially saving time and reducing cost and development risk.
We believe our ExPERT platform offers a compelling value proposition to our academic and biopharmaceutical customers due to: (i) the ability to use our technology to deliver almost any molecule into almost any cell type, including hard-to-transfect human primary cells, while maintaining high cell viability and function; (ii) the capacity to introduce larger and more diverse molecules, as well as multiple payloads, which exceeds the capabilities of other intracellular delivery technologies, such as viral vectors; and (iii) the flexibility to scale up from research to cGMP, manufacturing on a single platform—enabling the engineering of cells ranging from tens of thousands of cells to tens of billions of cells in a single transfection run in 30 minutes or less.
We believe our ExPERT intracellular delivery platform provides value across numerous applications in the life sciences market, including research, discovery, development, and manufacturing of next-generation, cell-based

therapeutics, as well as in biomanufacturing, such as transient protein production for drug discovery and manufacturing of other proteins, including biological therapeutics, viral vectors and vaccines, and small molecule drug discovery.
Our ExPERT technology platform is being used in the clinic to support the development of next-generation cell therapy approaches to treat human disease. Following the successful clinical development leading to FDA approvals of CAR-T cell therapies in blood-based cancers, developers have focused on improving efficacy, lowering the cost of manufacturing and/or expanding engineered cell therapies into new indications, such as solid tumors, as well as autoimmune and neurogenerative diseases. To address these goals, the ex vivo cell therapy industry has trended towards developing more complex therapies that require sophisticated engineering and gene manipulation as well as the use of different starting cell types.
In addition, we are committed to continued research and development investments in technology and scientific innovation to maintain our market leadership position.
Our Industry Background
As the cell therapy market continues to evolve, more complex approaches are being deployed to improve efficacy, reduce time to treat patients and expand the application of cell therapy to additional indications. The use of viral vectors carries several challenges, however, especially given the increase in complexity of these “next-generation” ex vivo cell therapy approaches, such as:
• Viral payload limitations. Many methods of gene manipulation require insertion of relatively large molecules, including proteins such as CAS9 RNP for CRISPR or plasmids. Viral vectors, particularly Adeno-Associated Virus (“AAV”), have fundamental payload capacity limitations, curtailing their utility for complex engineering systems. Additionally, the industry has continued to shift to using complex molecules including combination of proteins and mRNA which cannot be delivered by viral means.
• Concerns around toxicity. Given viruses used in gene therapy by default infect human cells, there continue to be questions around the safety profile associated with viruses. In particular, there are concerns over the potential for random integration of lentivirus and the widespread presence of neutralizing antibodies against many AAV serotypes used in gene therapies.
• Costs and time to market. Concerns exist regarding viral vector manufacturing capacity and the cost associated with viral development and manufacturing. Additional bottlenecks arise from demand for viral approaches, which has led to subsequent demand for cGMP plasmids. Furthermore, vein-to-vein manufacturing times remain high and efficiencies are needed to deliver cell therapeutic medicines to patients faster.
Novel intracellular delivery approaches are needed to support the increased complexity of the burgeoning cell therapy pipeline. Characteristics include reducing immunogenicity risk of viral vectors, the need to drive high efficiency of multi-molecule delivery while maintaining high cell viability and potency, reducing the risk of potential genotoxicity of multiplex editing (potential for translocations), the need to deliver a large number of molecules at scale, the ability to deliver to a large number of cell types in a time efficient matter, and the need to manufacture in a cGMP environment—all at a manageable cost.
The challenges of viral delivery methods and increased complexity of next-generation cell therapies has driven increased adoption of non-viral delivery technologies, such as electroporation. We believe our ExPERT technology is well positioned as a non-viral delivery platform in the cell therapy market. Originally developed in 1999 for the cell therapy market, we have systematically designed and improved the platform to deliver any molecule, into any cell at any scale, with high efficiency and under cGMP conditions. Our ExPERT platform is now the delivery backbone for a number of next-generation cell therapy programs that are in the clinic.
Our Agreements with Customers
11
Table of Contents
We have a diverse portfolio of clinical partners and licensees that mirror the overall next-generation engineered ex vivo cell therapies. While difficult to predict given uncertainty around regulatory approvals and clinical risk, according to Evaluate Pharma, a provider of commercial intelligence and predictive analytics to the pharmaceutical industry, the first next-generation ex vivo cell therapies using non-viral approaches could be approved in the United States as early as 2023.
Our platform’s ability to engineer a diversity of cell types (including CAR-T, chimeric antigen receptor Natural Killer cells (“CAR-NK/NK”), T cell receptor (“TCR”) and stem cells) and cell sources (autologous and allogeneic) enhances our opportunity by potentially providing SPL partnership revenues regardless of which approaches advance in the coming years. Additionally, our instruments and platform have been used in over 40 clinical trials to date for drugs being developed to treat a variety of indications, from hematological malignancies to solid tumors to inherited genetic disorders. We believe that the increasing number of publications highlighting the performance of our platform compared to other electroporation, transfection and transduction approaches will continue to drive acceptance of our products in the cellular engineering market segments.
In addition to sales of our instruments, as part of our business model we enter into the following types of instrument license agreements with our customers:
Research Licenses
Research licenses are agreements we have entered into with customers (which could be academic institutions or commercial entities), which provide access to the use of our instruments for preclinical research-only purposes, without the rights or ability to produce material for use in the clinic. Research licenses provide the customer with the ability to use the platform for research in exchange for a non-refundable, annual lease payment of typically $150,000 per instrument per year, or in certain circumstances under a sale of an instrument to a cell therapy user. We have entered into many research licenses to-date, either as (i) stand-alone research license agreements, (ii) research and clinical license agreements that do not have associated commercial rights or (iii) under an SPL partnership, which allows a customer to use the instrument for clinical development and potential commercial sale of a therapeutic product. Research licenses under a stand-alone research license agreement (as well as instruments purchased for research use) could represent opportunities for future SPL partnerships.
Clinical Licenses
Clinical licenses are agreements with academic institutions or commercial entities that provide access to the use of our instruments for the clinical evaluation and development of a therapeutic product intended for human use. In a clinical license, we retain title to the instrument and provide the customer with the ability to reference our FDA Master File (and international equivalents), use the platform for production of clinical material for human clinical use, as well as access to our application scientist team, all in exchange for an annual lease payment that typically approximates $250,000 per instrument per year for commercial customers. Academic clinical licenses can represent opportunities for future SPL partnerships to the extent that commercial entities seek and obtain rights to such programs from the academic institution.
Strategic Platform Licenses (SPLs)
Given our value proposition in non-viral delivery, we have established strategic relationships in the form of SPL partnerships with a growing number of leading cell therapy developers as they work to bring next-generation cell therapies into and through the clinic and advance those candidates to potential commercialization.
12
Table of Contents
Under these SPL partnerships and other license agreements with our customers, we retain title to the licensed instrument and associated intellectual property, and in exchange for an annual license fee per instrument, we provide our customers with non-exclusive access, for a defined field of use to our:
• cGMP-compatible platform, which enables early-optimization and scale-up from pre-clinical research into clinical development using our intellectual property portfolio;
• FDA Master File and Technical Files, which may accelerate and streamline development and reduce regulatory risk in the creation and development of our partners’ therapeutic drug candidates;
• experienced team of sales personnel and application scientists who work directly with our customers to solve cell engineering problems; and
• continuous know-how and cell engineering process improvements.
In return, these SPL partnerships provide us with the ability to receive downstream program-related precommercial milestone payments and, in most cases, commercial sales-based payments. In addition, from our SPL partnership customers, we receive both annual research and clinical license fees as well as payments from sales of our proprietary disposables as recurring revenue streams. Given growth in the cell therapy pipeline and increased investment in the space, we estimate that the number of potential SPL partnerships for us will continue to grow significantly, based on our estimates of growth in the cell therapy pipeline, growth in the number of therapeutic delivery entrants into the market and ongoing shift in the industry to non-viral delivery.
Our customer relationships may evolve to an SPL partnership after the customer’s drug candidate optimization and verification process nears completion and the clinical process development stage begins. Specifically, if a customer wishes to use our products in the clinical phase of process development, they will need to enter into an SPL partnership, as a customer must obtain clinical rights to perform clinical process development, including for engineering runs. Customer discussion for an SPL partnership can take place any time during our engagement.
Our SPL customers typically pay an annual license fee per instrument per year for a research license (for preclinical use) or per instrument per year for a clinical license (for clinical or commercial use) or in certain circumstances may purchase an instrument for research use. Partners also purchase associated single-use disposables and consumables as needed. Our SPL partners also commit to pay precommercial milestone payments for each therapeutic licensed under the agreement and produced using our platform, as they achieve key precommercial clinical development events (including, for example, IND filing, dosing of an agreed number of patients in a Phase 1 clinical trial, initiating a pivotal clinical trial, and Biologics License applications (“BLA”) approvals in specified regions). Almost all of our SPL partnerships also include a commitment to pay us post-approval sales-based payments for commercialized therapeutics.
We view our ability to sign SPL partnerships as a key measure of our success in partnering with leading therapeutic developers in the clinic, which then supports the performance of our platform.

Table of Contents
The following graphic is an example of typical single-product revenues from a representative SPL partnership:
Our SPL partnerships and research and clinical licenses may be terminated at the option of our customers at any time. Annual instrument lease fees are non-refundable and customers may not use our instruments or process assemblies after terminating their agreement with us. We retain title to the leased instrument in each of our licenses. Upon contract termination, our customers would be responsible for any further clinical studies or data development that regulators may require to allow a change in their cell engineering methodology. We have entered into 19 SPL partnerships with commercial cell therapy developers and, to date, none of our SPL partnership licensees has ever terminated their contract with us.
Of the over 125 potential programs allowed under our current SPL partnerships, 16 are active in the clinic, meaning they have at least an FDA-cleared investigational new drug application (“IND”). An IND is a request for authorization from the FDA to administer a therapeutic being investigated in humans in a clinical research setting. An IND must become effective before human clinical trials may begin. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, raises safety concerns or questions about the proposed clinical trial. Clinical trials then involve the administration of the investigational product to human subjects under the supervision of qualified investigators and are conducted under protocols detailing, among other things, the objectives of the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated.
5
Our 19 SPL partnerships have the potential to generate over $1.55 billion in precommercial milestone payments if all of the licensed programs were to achieve regulatory approvals. In addition, under the SPL partnerships, we typically have the potential to receive significant, sales-based commercial payments for approved products. However, clinical development involves a lengthy and expensive process with uncertain outcomes, including the results of pre-clinical research, as well as clinical trials demonstrating product safety and efficacy, and therefore our customers may not begin or complete clinical development, or may never receive FDA or other regulatory approval for all or any product candidates covered by their SPL partnership agreements with us, in which case we will not receive the full potential precommercial milestone payments or the sales-based commercial payments or royalties contemplated by our SPL agreements.

Our Products
ExPERT Instruments
The ExPERT instrument family was designed to provide a single unifying technology that can be used from concept to clinic, with both the research and clinical versions of the instrument incorporating the same underlying technology and protocols. Our customers have a choice of three different instrument versions that are standardized on the same technology to deliver equivalent high performance—the ATx, STx and GTx, as well as a portfolio of proprietary related disposables and consumables. In September 2022, we introduced a fourth instrument, the ExPERT VLx, for large-scale cell engineering. Customers can start with the lower to medium scale research instrument (ATx) and then scale up to the clinical version (GTx) without the need for re-optimization or re-validation. The STx provides the same scale as the GTx but is used for drug discovery applications, such as preclinical monoclonal antibody production, and not for human therapeutic use. The STx is not covered by our FDA Master File or our Technical Files.
We believe these systems will also be supportive of the commercial marketing of our partners’ therapeutic products which we enable. By allowing our customers to perform their research and process optimization on a research platform and seamlessly scale to a clinically validated, cGMP environment and 21 CFR Part 11 compatible clinical platforms, significant time and cost savings can be realized.
All our instruments have been designed to provide customers with the key features required for a scalable high-performance transfection solution. Each of our ExPERT instruments are benchtop with the same small footprint and have integrated touch screens with an intuitive Graphical User Interface (“GUI”), designed for simple training and operation. To support use in the cGMP suite for clinical manufacturing, our GTx ExPERT software is network capable to enable upload of electronic batch records to a local shared drive and has a software intermediary to facilitate integration and automated data transfer to cloud-based data management solutions. We have integrated hardware and software design solutions, manufactured under cGMP, that are tailored for use in cGMP manufacturing of clinical products for advanced cellular therapies.
The following chart summarizes the features of the four ExPERT instruments:

Table of Contents
ExPERT ATx: Research focused, static electroporation for small to medium scale transfection
Our ExPERT ATx static electroporation instrument is a research focused, high performance electroporation platform for small to medium scale transfection. The ATx instrument delivers high efficiency and viability at research scale and can utilize our range of PAs capable of transfecting from 75,000 up to 700 million cells. Additionally, our ATx instrument is compatible with all of our static PAs, which can also be used on our GTx instrument, allowing for a seamless transition to our clinical cGMP-compatible platform. The ATx is designed and used by our customers for early design of experiment and process optimization at small scale to minimize cell acquisition and reagent costs. Once optimized for the biological function with smaller numbers of cells, the process can be replicated and scaled before being transferred to the clinical platform (GTx) for eventual manufacturing in the cGMP suite or to the STx platform for drug discovery and bioprocessing applications.
ExPERT STx: Flow Electroporation for protein production and drug development
Our ExPERT STx, which is used in the field of protein production as well as other drug discovery applications, also incorporates our proprietary Flow Electroporation Technology for high yield transient expression of complex proteins, viral vectors, vaccines and biologics. Our STx instrument has high efficiency and can rapidly transfect from 75,000 up to 20 billion cells. When combined with flexible media strategies, the STx allows for substantial improvement in yields of high-quality, transiently expressed proteins while enabling reduced media costs.
Another key application area for the STx is expression of therapeutic targets for cell-based assays. Traditionally, drug screening has been performed using stable cell lines because conventional transfection technologies, such as lipofection, may induce changes to membrane composition, which does not offer the consistency and scalability that are critical for sensitive, high throughput screens. By enabling high efficiency transfection of multiple plasmids simultaneously into billions of cells, the STx provides drug developers with the ability to express complex, multi-subunit proteins, such as ion channels, in physiologically relevant cells. The high viability of our transfected cells leads to robust assay responses on multiple platforms, including automated electrophysiology and high content screening technologies.
Moreover, precise control over loading efficiency gives assay developers the ability to “dial in” optimal assay windows.

ExPERT GTx: Flow Electroporation for large scale transfection in therapeutic applications
The ExPERT GTx incorporates our proprietary Flow Electroporation Technology for use in the cGMP manufacturing of cellular therapies for use in the clinic. By incorporating the Flow Electroporation Technology, larger volumes of up to 20 billion cells can be electroporated within 15 to 20 minutes. With a processing potential that ranges from 75,000 to 20 billion cells on a cGMP, 21 CFR Part 11 compatible system, the GTx represents a platform for clinical electroporation at large scale.
The GTx integrates several design features that are critical for use in a cGMP setting, such as barcode reading capability to maintain positive identification of patient samples, 21 CFR Part 11 compatible software and networking capability for automated uploading of electronic batch records to either a central server or to a cloud-based data management platform. The GTx enables closed sample processing, on a system compatible with integration into cGMP manufacturing environments, and that has an established regulatory path supported by our FDA Master File and Technical Files.
ExPERT VLx: Designed for very large volume cell-engineering
The ExPERT VLx Large-Scale Transfection System is a cGMP compliant instrument specifically designed for very large volume cell-engineering. Using proprietary Flow Electroporation Technology, the VLx supports the ability to transfect up to 200 billion cells in less than 30 minutes—10 times the capacity of the STx and GTx. This system is designed for the rapid and large-scale production of recombinant proteins, monoclonal antibodies, viral vectors, vaccines, virus-like particles (“VLPs”), and allogeneic cell therapies. We launched the VLx under the ExPERT brand in September 2022 to provide customers with an easy to use, large-scale system that incorporates the benefits of the ExPERT platform for large-scale bioprocessing.
Disposables—Processing Assemblies (PAs)
Our range of disposable PAs is an important differentiator for us. We are not aware of any other company with the breadth and diversity of supported processing volumes that enable high efficiency electroporation flow, in single-well and multi-well formats, for use in both the research and clinical settings. We view our PA designs as one of the key contributors to the capacities, high efficiency and viability delivered by the ExPERT platform.
We have developed a broad range of PAs that are specially designed to process and electroporate the user’s chosen quantity of cells. Each PA contains two electrodes, between which a medical-grade gasket is sandwiched that has a unique well design consistent with the processing volume required and to allow maximum retrieval of cells. Our PAs are capable of electroporating cell volumes from small to large scale, in single and multi-well formats, for both research and clinical use. Cells are placed into the sample bag in large scale PAs, or into the well or wells in small scale PAs, and the
17
Table of Contents
PA is then connected to the instrument for processing. The instrument touch screen allows the operator to select the desired cell protocol that encodes the electroporation parameters, select the type of PA to be used and enter any sample specific information. Once the sample information has been entered, the operator will touch the “Start Processing” icon on the user interface and the sample will be rapidly processed. Larger volumes of cells are accommodated by larger capacity PAs and a set of simple software commands through the intuitive GUI.
Our ExPERT system uses two PA designs — a static cuvette used for smaller cell volumes (from 75,000 cells up to 200 million cells) and a cartridge design that is used for both static and Flow Electroporation for larger cell volumes (700 million up to tens of billions of cells). The Flow Electroporation PA (Flow PA) allows for processing of cellular volumes ranging from 10 mL to 100 mL and up to tens of billions of cells. The Flow PA consists of bags and associated tubing, made from medical grade materials, that are connected to the electroporation cartridge. Users transfer their cells and loading molecules to the sample bag, and the pump on either the GTx or STx instrument pumps a fixed volume of cells into the cartridge chamber where they are electroporated. Once the electroporation is complete, the cells are pumped to the collection bag and the chamber is filled with the next volume of cells for electroporation. This process is repeated until the entire sample volume is processed. The maximum volume of 100 mL of cells can be processed in approximately 15–20 minutes.
Examples of our two ExPERT PA designs are shown in the pictures below:
We have conducted extensive end-user research to continue improving the design of the PAs and the range of products available. We launched the ExPERT cuvette in 2020 based on customer feedback, which incorporated a new design to improve handling and ease of use and have continued to expand the availability the ExPERT PA portfolio design. We have also expanded our portfolio of multi-well cuvettes, which reduce manual handling and improve productivity in the lab, with the launch of our R-50x8. The R-50x8 is an 8-well cuvette capable of processing up to 225,000 cells in each well. By enabling eight samples to be processed in the same cuvette, a more efficient process can be achieved by users. We expect to convert our entire portfolio of PAs to the ExPERT design by the end of 2023. We plan to continue to support customers using legacy processing assemblies until they transition to our ExPERT products.
In 2022, we added the R-20K Flow Electroporation Processing Assembly for our STx and GTx platforms, which can process between 5 mL and 20 mL sample volumes, which can accommodate between 200 million and up to 4 billion cells. The R-20K assembly will allow clients to develop therapies at small or mid-scale volumes with improved cell recovery in a closed process adaptable format to assist in de-risking their manufacturing process at the electroporation step. To further support our customers’ sterile closed process workflows, we also introduced ‘Closed Process Electroporation Buffer’ products in two volume sizes, 500 mL and 1 Liter, which allow for the addition of our proprietary electroporation buffer to concentrated cell samples before electroporation. For our VLx Platform we introduced the R-1L Flow Electroporation Processing Assembly, which can process in 30 minutes or less between 100 mL and 1 Liter sample volume accommodating up to 200 billion cells in a single run. The R-1L assembly allows for

We are committed to strategically investing in improvements in the PA design and range of products to ensure that customers have solutions that address all of their volume and use requirements, in both research and clinical settings, including current development of advancements for PA that support the VLx.
Supporting Products
Our proprietary electroporation buffer, a balanced salt solution that protects cells during transfection, is formulated for use with all our instrument platforms and PAs. This consumable is used for all cell types, eliminating the need to change buffers as users switch protocols, cell types or scale up. The buffer is made in a cGMP facility, is fully chemically defined and is free of human or animal components, and is tested to meet technical, sterility and endotoxin specifications. This buffer formulation is a key contributing factor, in combination with instrument and PA design features, to the flexibility, high efficiency and viability that can be achieved by customers across the broad range of cell types processed using our platform.
Sales and Marketing
We follow a direct sales model in North America, the United Kingdom, and Europe, while also selling through third-party distributors in Asia and some regions of Europe. As of December 31, 2022, we had over 25 field sales and application scientists located in the United States, the United Kingdom, and several regions in Europe and Asia. Since the commercial launch of our first Flow Electroporation instrument, the installed base of our instruments has grown to more than 600 instruments globally.
Our sales force and field application scientists and international partners inform our current and potential customers of current product offerings, new target applications and advances in our technologies and products. As our primary point of contact in the marketplace, our field teams focus on delivering a consistent marketing message and high level of customer support, while also working to help us better understand the evolving market and customer needs. We intend to

expand our sales, support, and marketing efforts in regions such as the Asia-Pacific region. We currently use distributors in countries in these regions, such as in China and Japan, supplemented by dedicated MaxCyte team members, and continuously assess the need for direct sales and local support personnel to supplement our distributors’ resources. As we expand into a new geography, we generally rely initially on third-party distributors until we are able to recruit a direct sales force, field application scientists and business development resources in the country or region.
Our business model is focused on identifying new applications in cell engineering to enable our customers to develop better medicines and maximize use across our customers’ value chains. This is enabled through customer partnerships that allows us to further understand the critical applications for our technology and inform our future developments and market expansion.
Research and Development
Investment in research and development is at the core of our business strategy. Members of our research and development team specialize in many functional areas including molecular biology, cellular biology, physics, gene editing, cell culture, protein manufacturing, process development, mechanical engineering, cell handling processes, electroporation algorithm development and customer technical support.
Our research and development teams are aligned into two teams, applications and instrumentation. The application team is responsible for developing data on key applications, including improving approaches to cell handling and cell culture; designing, developing and enhancing electroporation protocols; developing and enhancing cell engineering applications, and performing product testing and quality assurance activities. The instrumentation engineering team focuses on developing and improving electroporation instruments and PA disposables to meet our partners’ wide range of needs from research to commercialization in a GMP environment. The research and development functional teams work together as a core team, following a stage-gate process to develop, qualify and launch new products to market.
Other research and development activities include customer technical support such as cell processing techniques, instrumentation training and application support. Most of our research and development operations are conducted in our Maryland facility.
We have made substantial investments in product and technology development since our inception. Research and development expenses totaled $19.5 million and $15.4 million in the years ended December 31, 2022 and 2021, respectively.
We expect our research and development expenses to increase significantly for the foreseeable future as we develop data supporting the use of our products in various applications and continue to enhance our existing products as well as develop new products for our current and new markets.
Manufacturing and Supply
We design, develop and manufacture our single use PA disposables and conduct final functional testing in our Maryland facility, and for risk mitigation, we utilize a third-party manufacturer for a portion of the PA disposables supply. In addition, we design, develop and manufacture our ExPERT instruments in-house. Our in-house manufacturing and design function is certified as ISO 9001 compliant and our manufacturing facility and controlled-access shipping, receiving and storage spaces are located at our current headquarters in Maryland. We relocated our operations, including inventory and manufacturing, to a significantly larger space in a new facility during 2022.
Instruments
Our range of ExPERT instruments are manufactured, tested and shipped from our Maryland facility under cGMP. Several custom components of our ExPERT instruments are fabricated by third-party suppliers. The assembly of technology-sensitive components and the final assembly is completed in-house. Presently, our Maryland manufacturing

facility can support the production of ExPERT instruments in excess of anticipated demand, and we plan to continue obtaining the space and staffing necessary to meet customer demand for the foreseeable future.
Processing Assemblies
Our PAs are only available from us and are designed for use only with our instruments. The PAs are designed, developed, tested and shipped from our Maryland facility. We outsource supply and manufacturing of key PA components. Final clean-room disposables assembly is performed at our headquarters facility and at a third party. In-house cleanroom PA assembly activities were initiated in 2022 in order to enhance operational control over quality, expand capacity, enable automation implementation, provide for multiple manufacturing sites and improve other areas of operations. In addition, in-house manufacturing allows research and development to more rapidly develop new products and enhancements as a result of housing research and development in the same facility.
Supply
For both instrument and PA manufacturing, we regularly assess our supply chain to ensure availability of components, our ability to respond to customer demand for our products and to qualify multiple suppliers. We have relationships with multiple custom parts manufacturers and electronics suppliers that can provide components for our instruments, including components currently provided by a single source. Approximately 34% of our inventory held at December 31, 2022 was purchased from one supplier. Single source suppliers are chosen for their business stability and scalability to minimize risk. If a single source supplier has a part or process that is time-consuming to transfer to another supplier, our approach is to hold enough inventory of that part to allow adequate time for technical transfer and qualification wherever possible. Our ongoing strategy is to maintain adequate levels of inventories at all times and to qualify at least two suppliers for critical components, and we plan to continue the diversification of our supply chain as we scale. This inventory strategy was designed to minimize supply chain risk and as a result we are currently able to ship on demand and to date have never had a backorder for a product.
Competition
The life sciences market is highly competitive and dynamic, reflecting rapid technological evolution and continually evolving customer requirements. There are other companies, both established and early-stage, that have or are developing electroporation and other non-viral delivery technologies that could be applicable to both bioprocessing and cell engineering. These companies include Lonza Group AG, Thermo Fisher Scientific Inc., Miltenyi Biotec, Bio-Rad Laboratories, Inc. and Harvard Biosciences Inc. (BTX), as well as several other smaller companies, including spinouts from academic labs.
Some of these companies may have substantially greater financial and other resources than us, including larger research and development staff or more established sales forces. Other competitors are in the process of developing novel technologies for the life sciences market which may lead to products that rival or replace our products.
For further discussion of the risks we face as a result of competition, see “Risk Factors—Risks Related to Our Business and Growth Strategy—We may be unable to compete successfully against our existing or future competitors.”
Intellectual Property
Our intellectual property strategy has been, and still is, to obtain patent protection in relevant jurisdictions over our instruments, methods utilizing our instruments, as well as design patents over the ExPERT system. As part of this strategy, we have focused on obtaining protection for our non-viral delivery platform to the extent possible, particularly in the United States and other key jurisdictions of commercial value. As of March 8, 2023, we have more than 150 granted U.S. and foreign patents, including in foreign jurisdictions such as Australia, Canada, Japan, China, South Korea and certain countries in Europe, as well as over 95 pending patent applications worldwide. The main focus of our patent coverage is to protect our Flow Electroporation process, as well as the processing assemblies/disposables, control and
21
Table of Contents
process elements, and methods/applications of using our non-viral delivery platform. Our patent portfolio provides protection over our instruments and related methods through at least 2028 and over our electroporation applications and methods through 2034. We are also working to secure design protection of the ExPERT system, which has the potential to provide protection through at least 2036.
In addition to our granted patents and filed applications, we maintain and protect a number of different trade secrets related to our cell processing technology and other core technology areas, such as improvements made to protocols, pulsing patterns, proprietary buffer and formulations developed by us. Our years of accumulated know-how and the technical expertise of our employees provide us with a competitive advantage. We use our know-how and technical expertise to optimize and update our proprietary methods and protocols, such as cell handling and preparation techniques unique to different cells and target molecules, which we confidentially share with our customers.
We maintain the confidentiality of our trade secrets, know-how and proprietary methods and protocols to protect our intellectual property from competitors. One key element of this protection is our FDA Master File and Technical Files described in more detail below, which allow us to submit to the regulatory authorities confidential detailed information about our ExPERT system and disposables. The relevant submission can be referenced by our customers or licensees to support their own regulatory filings without the need for us to disclose the confidential information contained in the FDA Master File and Technical Files.
We also seek to protect our brand through procurement of trademark rights. As of March 8, 2023, we owned 17 registered trademarks in the United States, 191 registered foreign trademarks, 13 pending U.S. trademark applications, and more than 31 pending foreign trademark applications. Our registered trademarks and pending trademark applications include trademarks for our company name, a stylized version of ExPERT, and our logo. In order to supplement protection of our brand, we have also registered several internet domain names.
Government Regulation
The FDA and similar governmental authorities regulate, among other things, the research, development, testing, manufacturing, clearance, approval, labeling, storage, recordkeeping, advertising, promotion, marketing, distribution, post-market monitoring and reporting, as well as import and export of technologies including biological drug products.
Our biopharmaceutical and life sciences customers are subject to extensive regulations by the FDA and equivalent regulatory authorities in other countries, regarding the conduct of preclinical studies and clinical trials, in the manufacture of product candidates and products for use in humans (i.e., “Good Manufacturing Practice” laws and regulations) and the marketing authorization and commercialization of biological drug products.
The activities of sponsors, applicants and manufacturers are subject to regulation of those jurisdictions where the research or manufacturing occur, and also jurisdictions for which applications are planned or have been made and the product is intended to be marketed.
Although we are not engaged in directly regulated activities, our customers will generally assess our products for sufficiency in meeting their regulatory needs, and may impose rigorous quality or other regulatory compliance requirements on us as their supplier through supplier qualification processes and customer contracts.
We have established a quality management system (under ISO 9001:2015 standards) which is designed to respond to customer expectations and needs and support customer adherence to applicable regulatory requirements. The technologies we offer for potential use by customers in a cGMP environment are produced under this ISO 9001:2015 quality management system.

Master Files and Technical Files to Support Customer Regulatory Submissions
Our core business is focused on developing our proprietary and patented electroporation technology platform, which is used by our customers in research and development applications as well as for manufacture of commercial cell therapies. In order to support our customers’ use of our platform, we have voluntarily submitted a Master File to the FDA, Center for Biologics Evaluation and Research and Master Files or Technical Files to comparable regulatory authorities in other jurisdictions, including Canada, Japan, the United Kingdom and Austria, and provide nonexclusive Letters of Authorization to the Master or Technical Files under contractual agreements with our customers. We have also discussed the potential to submit a Master File with the Therapeutic Goods Administration in Australia. In this way, the regulatory body may review information on our platform in the context of its utilization by our partners in regulated products, for example, as described in our customers’ INDs or BLAs. We continuously update the Master and Technical Files in order to support the regulatory activities of our customers. The FDA and regulators in other countries allow Master and Technical Files, but they do not approve them. Rather, they review them in the context of evaluating the submissions by our customers that reference our files.
U.S. Healthcare Laws and Reform
In the United States, there are federal and state healthcare laws that constrain the business or financial arrangements and relationships through which our customers who use our platform and we, if we develop a product, research, sell, market and distribute products. Such laws include federal and state anti-kickback laws, false claims laws, transparency laws and health information privacy and security laws. Violations of these laws can lead to significant administrative, civil and criminal penalties, including sanctions, damages, disgorgement, monetary fines, possible exclusion from participation in government healthcare programs such as Medicare and Medicaid, imprisonment, additional reporting requirements and/or oversight obligations, contractual damages, reputational harm, diminished profits and future earnings and curtailment or restructuring of operations.
Additionally, in the United States and some foreign jurisdictions there have been, and continue to be, several legislative and regulatory changes and proposed reforms of the healthcare system in an effort to contain costs, improve quality, and expand access to care, including the proposed modification to some of the aforementioned laws. In the United States, there have been and continue to be a number of healthcare-related legislative initiatives that have significantly affected the healthcare industry. These reform initiatives may, among other things, result in modifications to the aforementioned laws and/or the implementation of new laws affecting the healthcare industry. Similarly, a significant trend in the healthcare industry is cost containment. Third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. Our ability to commercialize any of our products successfully, and our customers and collaborators’ ability to commercialize their products successfully, will depend in part on the extent to which coverage and adequate reimbursement for these products and will be available from third-party payors. As such, cost containment reform efforts may result in an adverse effect on our operations.
The Foreign Corrupt Practices Act
The Foreign Corrupt Practices Act (“FCPA”), prohibits any U.S. individual or business from paying, offering, or authorizing payment or offering of anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the United States to comply with accounting provisions requiring the company to maintain books and records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations.
Data Privacy and Security Laws and Regulations
In the ordinary course of business, we collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect, secure, dispose of, transmit, and share (collectively, process) personal information, such as clinical
23
Table of Contents
trial data and other health data. Accordingly, we may be subject to numerous data privacy and security obligations, including federal, state, local, and foreign laws, regulations, guidance, industry standards, external and internal privacy and security policies, contractual requirements and other obligations related to data privacy and security. These frameworks are evolving and may impose potentially conflicting obligations. Such obligations may include, without limitation, the Federal Trade Commission Act , the California Consumer Privacy Act of 2018, as amended by the California Privacy Rights Act of 2020 (“CPRA”) (collectively, “CCPA”), the European Union’s General Data Protection Regulation 2016/679 (“EU GDPR”), the EU GDPR as it forms part of United Kingdom law by virtue of section 3 of the European Union (Withdrawal) Act 2018 (“UK GDPR”), the ePrivacy Directive, and wiretapping laws. Further, the federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”), imposes specific requirements relating to the privacy, security, and transmission of individually identifiable health information. In addition, several states within the United States, such as Virginia, Colorado, Connecticut, and Utah, have enacted comprehensive data privacy laws, and similar laws are being considered at the federal, state, and local levels.
The EU GDPR, UK GDPR, and CCPA are examples of the increasingly stringent and evolving regulatory frameworks related to personal information processing that may increase our compliance obligations and exposure for any noncompliance. European data privacy and security laws (including the EU GDPR and UK GDPR) impose significant and complex compliance obligations on companies that are subject to those laws, notably with respect to the processing of health-related data from European Economic Area (“EEA”) or United Kingdom-based individuals. Additionally, the CCPA applies to personal information of consumers, business representative, and employees who are California residents, imposes specific requirements on covered businesses, provides for administrative fines of up to $7,500 per violation and allows private litigants affected by certain data breaches to recover significant statutory damages. In addition, the CPRA expanded the CCPA’s requirements. Furthermore, U.S. federal and state consumer protection laws may require us to publish statements that accurately and fairly describe how we handle personal information and choices individuals may have about the way we handle their personal information.
See the section titled “Risk Factors – Risks Related to Our Regulatory Environment and Our Industry” for additional information about the laws and regulations to which we are or may become subject and about the risks to our business associated with such laws and regulations.
Employees and Human Capital
As of December 31, 2022, we had 125 full-time employees, 68 of which have advanced degrees, including 25 with Ph.D. degrees.
Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, training, incentivizing and integrating our existing and new employees, advisors and consultants. The principal purposes of our equity incentive plans are to attract, retain and reward personnel through the granting of equity-based compensation awards in order to increase shareholder value and the success of our company by motivating such individuals to perform to the best of their abilities and achieve our objectives.
None of our employees is represented by a labor organization or under any collective-bargaining arrangements. We consider our employee relations to be good.
