Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our consolidated financial statements and related notes thereto included elsewhere in this Annual Report on Form 10-K,as well as the other information provided from time to time in our other filings with the SEC. Some of the information contained in this discussion and analysis or set forth elsewhere in this annual report, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. As a result of many factors,our actual results could differ materially from those discussed in or implied by these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in the section of this Annual Report on Form 10-K titled “Risk Factors.” Please also see the section titled “Special Note Regarding Forward-Looking Statements.”

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 technology, 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.

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 therapies. The ExPERT family of products includes four instruments, which we call the ATx, STx, GTx and VLx, and related software protocols, as well as a portfolio of proprietary related PAs and consumables. We launched the VLx instrument in September 2022.

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 200 granted U.S. and foreign patents and more than 100 pending patent applications worldwide.

From leading commercial cell therapy drug and biologic developers and top biopharmaceutical companies to top academic and government research institutions, including the 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 a majority of the top 25 pharmaceutical companies based on 2023 global revenue, to hundreds of biotechnology companies and academic centers focused on translational research. As of December 31, 2024, we have placed more than 760 of our electroporation instruments with customers worldwide.

Historically, we have financed our operations primarily from the issuance and sale of equity securities, previous debt borrowings and cash flows from operations. On August 3, 2021, we issued and sold 15,525,000 shares of common stock in our U.S. IPO at a price to the public of $13.00 per share, inclusive of 2,025,000 shares issued pursuant to the full exercise of the underwriters’ option to purchase additional shares. The IPO generated gross proceeds to us of $201.8 million. We received aggregate net proceeds of $184.3 million after deducting aggregate underwriting commissions and offering costs of $17.6 million.

We believe that our current cash, cash equivalents and short-term investments will enable us to fund our operating expenses and capital expenditure requirements for at least the next 12 months from the date of the filing of this Annual

Report. We have based this estimate on assumptions that may prove to be wrong, however, and we could exhaust our available capital resources sooner than we expect. See “Liquidity and Capital Resources” below for more information about our current capital resources.

Since our inception, we have incurred significant operating losses. Our ability to generate revenue sufficient to achieve profitability will depend on the successful further development and commercialization of our products. We generated revenue of $38.6 million and $41.3 million for the years ended December 31, 2024 and 2023, respectively, and incurred net losses of $41.1 million and $37.9 million for those same years. As of December 31, 2024, we had an accumulated deficit of $216.9 million. We expect to continue to incur net losses as we focus on growing commercial sales of our products in both the United States and international markets, including growing our sales teams, scaling our manufacturing operations, and continuing research and development efforts to develop new products and further enhance our existing products.

We believe we have a diversified revenue model with revenue generated from multiple sources including recurring license fees, sales of instruments and related PAs and participation in the clinical and commercial success of some of our customers through milestone and sales-based payments under SPL agreements.

Key Factors Affecting Our Performance

We believe that our financial performance has been, and in the foreseeable future will continue to be, primarily driven by the following factors. While each of these factors presents significant opportunities for our business, they also pose challenges that we must successfully address in order to sustain our growth and improve our results of operations. Our ability to successfully address the factors below is subject to various risks and uncertainties, including those described in this Annual Report under the heading “Risk Factors.”

Sales and Licenses of Instruments

Our financial performance has largely been driven by, and in the future will continue to be impacted by, the rate of sales and licenses of our ExPERT family of proprietary Flow Electroporation instruments to existing and new customers. We currently market four versions of our instruments, the ATx, the STx, the GTx and the VLx. The ATx is primarily to academic institutions and investigative research users. The STx is primarily sold to end users for research and drug discovery purposes, and the GTx is licensed to customers for research, clinical or commercial use or sold for research use in certain circumstances or sold to academic centers for research or clinical use. We launched the VLx in September 2022 to provide our customers with an easier to use system that incorporates the benefits of the ExPERT platform. We view the demand for our instruments, whether in the form of sales or license, as an indicator of the health of our current business and as a predictor of future instrument sale and license revenue. As described below, we separately sell proprietary single-use PAs, which we call PAs, that are necessary for our customers to use our electroporation instruments. Therefore, depending on the number of instruments that have been sold or are under active license, we have insight into the demand for PAs that will also translate to future revenue for us.

Our sales model varies based on the activity of the end customer, such as whether they are a translational research center, an academic center, a company focused on drug or biologic discovery, or a company engaged in cell therapy development, and the customer’s intended use of our platform. If our customer intends to use our platform for research or discovery only, we typically sell the instrument outright. Each of the ATx, STx, GTx and VLx instruments have different prices based on the instrument’s features, with the VLx being the most expensive. When we sell an instrument, we also provide a non-exclusive license to our intellectual property for the customer to use the instrument broadly for research or discovery, as applicable. In the case of a sale, title to the instrument conveys to the buyer, but we retain ownership of intellectual property rights and software and protocols loaded onto the instruments.

The sales cycle for our cell engineering instruments varies widely and typically ranges from approximately six to approximately 12 months, with the actual period depending on project stage, budget process, equipment prioritization and the general financial status of the customer or the market in general. As a result of this lengthy and unpredictable sales cycle, we expect that we may be prone to quarterly fluctuations in our instrument sales revenue.

For cell therapy customers who use our technology to develop engineered cells for human therapeutic use in clinical trials or, if approved by regulatory authorities, for commercial sale, we license our platform on a non-exclusive basis in exchange for an annual fee per instrument licensed. This license fee varies based on whether the instrument is being used for preclinical or clinical purposes. Once we have a research or clinical license with a customer, we generally have high visibility into future license revenue from this customer. It is possible, however, that our future license revenue could be impacted by failure of the customer therapeutic candidates to progress through clinical development for reasons unrelated to the successful use of our instruments, such as toxicity, lack of efficacy, funding constraints, changes in development priorities, patient access limitations or regulatory challenges. For any of these reasons, a customer could determine not to renew or to enter into additional licenses with us, which could result in our actual future license revenues differing from our estimates and projections.

Our installed base of electroporation instruments has grown to over 760 instruments as of December 31, 2024. This installed base includes both instruments sold to customers and instruments licensed for research and clinical use. Because of the size of the drug and biologic discovery market and our long history in that market, the installed base of instruments is currently weighted more heavily towards instruments sold for discovery and research applications. However, since each licensed instrument provides us with ongoing license revenues, the share of revenues from licensed instruments may grow as a share of our total revenue mix.

We plan to further grow our installed base of ExPERT instruments through additional sales and licenses to our current customers and through the sale or license of instruments to new cell therapy, product discovery, academic and other customers. To achieve this goal, we intend to further expand our commercial infrastructure, including through the expansion of our sales force and field application scientists. We have expanded our sales force and field application scientist count over the past several years and now have over 33 dedicated field sales and application scientist professionals globally. Our candidate identification and hiring process is stringent, and there can be no assurance that we will be able to continue to recruit the high level of candidates that make up our current team.

In addition, we have numerous collaborations in place with academic and commercial institutions to further expand our capabilities and supporting data in new cell engineering applications. Recent sales efforts have also focused on expanding our presence in translational academic centers, which we view as a potentially meaningful source of installed base expansion given the increased industry focus on, and government funding allocated to, cell therapy. Academic translational centers have been a strong source of cell therapy innovation and commercial spinouts in the cell therapy sector.

We expect license revenue to continue to grow as those customers move their existing drug or biologic development programs into later-stage clinical trials and advance their preclinical pipeline programs into clinical development. In addition, we expect new customers to emerge and contribute to these revenues, particularly given the underlying growth in the cell therapy pipeline among companies in this industry, availability of capital to support such companies, and in particular the switch by some of these cell therapy companies away from viral approaches to non-viral approaches.

Sales of Processing Assemblies and Consumables

In addition to instrument sales, our current and future revenue is dependent on sales of our proprietary PAs, as well as the sale of our proprietary consumables, for use with our instruments. We sell PAs that are intended either to support research use or use in cGMP clinical research applications. The PAs differ in terms of their volume capacities and the associated numbers of cells that can be processed in each electroporation sequence with a particular PA, as well as the number of transfection experiments that can be performed in a single electroporation process. Our PA pricing varies based on the volume of cells processed and the number of transfections per PA.

76

Table of Contents

We expect that as our installed instrument base grows, our sales of PAs and consumables will grow accordingly, especially as cell therapy programs continue to progress through clinical development and potentially become commercial-stage, thereby increasing the number of PAs needed by customers. We are also developing and intend to launch new PAs that target previously unserved subsegments across the bioprocessing and cell therapy markets, which could further increase our PA sales. However, both the number of PAs used per instrument, as well as the specific PA used, is highly variable across our customer base and depends on several factors, including:

•the purpose for which the customer is using the platform;

•the relative pricing of our PAs;

•the progression of cell therapy products through preclinical and clinical development;

•whether the cell therapy customer uses a centralized or decentralized manufacturing process;

•the customer’s target indication, which can result in variations in patient numbers needed for clinical trials; and

•whether the cells to be processed using our platform are patient-derived, donor-derived or cell line-derived.

With considerable variability of processes, even within the same indication, such as is the case for allogeneic genetically-modified cell therapies, such as CAR-Ts, and the nascency of the cell therapy industry, we expect that it may take several years for us to gain visibility into how these factors will impact our PA revenue over time.

We continuously re-evaluate our PA portfolio based on customer needs and have introduced, and intend to continue to introduce, new PAs, improvements to existing PAs, and complementary products. Some new PAs may fail to be used in line with our expectations when they are launched. While we also price PAs based on the value provided to the customer, introduction of new PAs could cannibalize our existing PA portfolio more than we anticipated if customers find the new products to be a better solution for their applications or workflows.

Strategic Platform Licenses (SPLs)

Typically, our cell therapy customers will either purchase our ATx instrument for research purposes or purchase or obtain a research use license of our GTx instrument technology in order to validate the use of our technology in their programs and to progress their preclinical work towards clinic trials. However, once a cell therapy customer using one of our ExPERT instruments advances their preclinical research to a stage where they are planning to enter clinical development, they need to enter into a licensing arrangement with us for the rights to clinical and/or commercial use of our instrument. Our customers typically negotiate the terms of those licenses during research and preclinical development.

We refer to these arrangements as SPL agreements, the terms of which contain not only higher annual, non-exclusive fees for the clinical use of the instrument, but also allow us to share in the economics of the customer’s programs. We have 29 SPL partnerships with commercial cell therapy developers, On average, our current SPL agreements allow for approximately six product candidates per license, although this average may change over time. SPL agreements typically include potential payments to us upon the customer’s achievement of specified clinical development or regulatory milestones, as well as potential sales-based payments to us, which could be payments based upon the achievement of specified sales levels and/or royalty payments that are a percentage of the customer’s net sales. The amount of each milestone payment is typically correlated in size with value-creating, precommercial clinical progress events or commercial sales levels.

Under our current SPLs, one program is in commercial stage, and 18 programs are currently in clinical development, meaning they have at least an FDA-cleared IND application or foreign equivalent. Our 29 SPLs have the potential to generate greater than $2 billion. This figure includes both existing active SPL programs currently in clinical development and future SPL programs that are encompassed in our SPL agreements. From the 18 active clinical programs under our SPL agreements, the total pre-commercial milestone opportunity can exceed $220 million if all of

77

Table of Contents

the active programs were to achieve regulatory approvals. We have already received about $10 million of milestone revenue from active programs. However, our actual milestone revenue from these agreements will likely be lower, as not all programs covered by each agreement will become and remain active programs in a customer’s development pipeline or successfully complete the clinical development process. Further, each agreement typically includes programs that have not been specifically identified, or for which a candidate may never be identified or developed by the customer.

Our strategy is to capitalize on the growth in the number of cell therapy developers by entering into new SPL agreements. We entered into six agreements in 2024.

For the year ended December 31, 2024, two cell therapy companies with which we have entered into an SPL agreement accounted for 32% of our total revenue, and our five largest SPL customers accounted for an aggregate of approximately 46% of our total revenue for the year through a combination of instrument license fees, milestones realized and processing assembly revenue.

Our future milestone revenue under our SPL agreements will depend in large part on the clinical and regulatory achievements of our customers. Generally, precommercial milestone payments become larger as programs move through clinical development. We rely in part on our customers’ public disclosures around regulatory timelines to forecast our receipt of precommercial milestone payments. While we expect our forecasting ability to improve over time as more of our customers’ programs advance through clinical development and the number of clinical programs covered by our licenses expands, given the early nature of the cell therapy clinical market, we expect our realization of precommercial milestones to be somewhat unpredictable.

In addition, the potential for sales-based payments once a customer’s product is approved and in commercial use is unknown and variable based on a number of factors, including inherent clinical risk, potential changes in the customer’s strategy, the designated indication and its impact on the potential number of patients to be served and the competitive products available to patients, product pricing and reimbursement structures, our customer’s commercial manufacturing plans and the inherent unknowns in adoption of next-generation cell therapies relative to other modalities.

Gross Margins

We have generated overall gross margins of over 80% for the last six years, although our margins vary depending on our revenue mix from instruments, PAs and milestones under SPL agreements and other factors. We price our instruments at a premium given what we believe to be the broad benefits of our platform, and the limited availability of alternative, clinically validated non-viral delivery approaches. However, the market for non-viral delivery is highly competitive, and introduction of a cGMP-grade platform by a competitor that delivers similar performance across a similar diversity of cell types could negatively impact our business and lead to increased price pressure that could negatively impact our gross margins. In addition, part of our growth strategy is to expand into new regional markets, which could require the use of distributors and/or our participation in more competitive environments, which could impact our ability to price our instruments at a premium and could negatively impact our ability to enter into SPL agreements on terms similar to those currently in effect.

We expect our gross margins to benefit from realization of the economics from our SPL agreements described above, to the extent that such milestones and/or sales-based payments grow to be a significant proportion of overall revenues, as there is no cost of goods sold associated with such revenue. However, realization of these potential revenues is uncertain. Margins may also experience downward pressure during the investment phase of our internal PA production ramp up, increases in labor and materials costs, expansion of our PA portfolio, future design changes or the mix of PAs sold, or other factors, but may benefit in the mid-to-long term as PA production becomes more automated.

Key Business Metrics

In addition to revenue, we regularly review several key business metrics to evaluate our business, measure our performance, identify trends affecting our business, formulate financial projections and make strategic decisions. These key metrics include:

With respect to the numbers of programs under license, in many cases we make estimates of such programs based on our contract terms with our customers and our knowledge about our customers’ clinical progression of their programs. We rely, in part, on our customers’ public disclosures around regulatory timelines to forecast our receipt of precommercial milestone payments. However, it is possible that some programs may have become dormant or inactive without our knowledge, some new programs may be identified and some programs may progress further in clinical development without our knowledge if the customer has not made a public announcement. While we expect our forecasting ability to continue to improve over time as more of our customers’ programs move through clinical development and the number of clinical programs covered by our licenses expands, given the early nature of the cell therapy clinical market, we expect our realization of precommercial milestones to be somewhat unpredictable. This number may fluctuate due to the success of our commercial partners. Additionally, the addition of a large SPL agreement in which one SPL customer uses multiple instruments as part of their research, clinical or commercial program, may dilute the percentage of commercial programs currently in the clinic.

As of the dates presented, our key metrics described above were as follows:

Components of Our Results of Operations

Revenue

We generate revenue principally from the sale of instruments, single-use PAs and consumables as well as from licenses to our customers. Our SPL agreements also include associated clinical progress milestones and sales-based payments to us, in addition to annual license payments. Sales of instruments and PAs under contracts with customers are classified as product sales in our consolidated financial statements. Revenue from SPLs, including payments that we may receive from our customers based on their achievement of specified clinical development or commercialization milestones, are classified as leased elements in our consolidated financial statements.

Our business and revenue growth strategy currently consists of the sale or instruments, the sale of PAs and consumables, and SPL license fees. We record revenue from the sale of instruments, PAs or consumables upon shipment to a customer. Licenses are typically invoiced annually at the start of each license period and are accounted for as monthly revenue over the license term with the expectation of continuing customer renewals of their licenses. As our customers achieve clinical progress milestones and/or sales-based payment milestones, we recognize the full value of the milestone as revenue. In addition, as customers use instruments they have either purchased or included with their license, they typically replenish their supplies of PAs and consumables through recurring purchases. Although customers are not contractually obligated to renew their licenses or to purchase additional PAs or consumables and may decide not to do so solely in their own discretion, license fees and PAs and consumable revenue streams have historically formed an important component of our revenues, and we believe they provide insight into our future performance. We consider these sales and license revenue streams to be recurring revenues.

In order to evaluate how our sales are trending across key markets, as well as the contribution of program economics from our SPL agreements, we separately analyze revenue derived from our core revenue, as well as the performance-based milestone revenues we recognize under our SPL agreements. Core revenue includes sales instruments, PAs and consumables, and research and clinical licenses, while non-core revenue relates to SPL program-related revenue. We recognize both core and non-core revenue in accordance with generally accepted accounting principles in the United States. (“U.S. GAAP”)

Program-related revenue includes precommercial milestones earned and recognized as revenue during the period. Once SPL customers achieve regulatory approval for and commercialize their products, in nearly all cases we will also be entitled to receive sales-based payments which may be milestone payments upon achievement of specified levels of net sales and/or royalties expressed as a percentage of net sales. We have not received any commercial payments from our SPL customers to date. As our customers progress their programs and achieve additional milestones, our SPL program revenue is expected to constitute a growing portion of our total revenues in future periods.

We also offer our customers extended warranty and service plans. Our extended warranty and service plans are offered for periods beyond the standard no-fee, one-year warranty that customers who purchase instruments receive. Research and clinical licenses include a warranty during the license term without additional charge. Extended warranty and service plans generally have fixed fees and terms ranging from one additional year to four additional years and include an annual calibration. We recognize revenue from the sale of extended warranty and service plans over the respective coverage period, which approximates the service effort provided by us. Warranties are typically not a material revenue stream for us and included in other revenue.

Product Sales

Revenue from contracts with customers includes revenue from the sale of instruments, PAs and consumables. Customers purchase an ATx, STx, GTx or VLx depending upon their intended use and all customers purchase PAs and consumables for use with our instruments. Commercial customers may not use a purchased instrument for clinical or commercial processes.

We expect product sales revenue to increase in future periods as our market and customer base grow.

80

Table of Contents

License Revenue

License revenue consists of revenue from research and commercial licenses. These licenses consist of fixed license payments and variable milestone payments that are dependent on our customer's achievement of clinical milestones. Typically, licenses that provide for clinical or commercial use also include sales-based milestone payments (and/or sales-based royalties in some cases) upon the commercialization of the customer's product. Under our research and clinical licenses, we provide our instruments and associated software to customers for non-exclusive use of our technology for research and/or specific clinical programs, typically along with rights for commercial use upon regulatory approval of the customer's products. We also provide scientific and regulatory support to our clinical use licensees to help them improve process optimization and facilitate their regulatory submission process.

We expect license revenue to increase in future periods as our market and customer base grow.

Cost of Goods Sold

Cost of goods sold primarily consists of costs for raw material parts, contract manufacturer costs, salaries, overhead, other direct costs related to sales recognized as revenue in the period, and licensed equipment depreciation.

We expect that our cost of goods sold will increase or decrease primarily to the extent that our instrument and PA and consumable revenue increases and decreases.

Gross Profit and Gross Margin

Gross profit is calculated as revenue less cost of goods sold. Gross margin is gross profit expressed as a percentage of revenue. Our gross profit in future periods will depend on a variety of factors, including sales mix among instruments, PAs, consumables and milestones, the specific mix among types of instruments or PAs, the proportion of revenues associated with licenses as opposed to sales, the share of revenues composed of milestones, changes in the costs to produce our various products, the launch of new products or changes in existing products, our cost structure for manufacturing including changes in production volumes, the proportion of sales made through third-party distributors, and the pricing of our products which may be impacted by market conditions.

Operating Expenses

Research and Development

Research and development expenses consist primarily of costs incurred for our research activities related to advancing our technology and development of applications for our technology, including research into specific applications and associated data development, process development, product development (e.g., development of instruments and PAs and consumables, including hardware and software engineering) and design and other costs not directly charged to inventory or cost of goods sold, such as supply chain development and design and management of quality systems.

These expenses include employee-related costs, such as salaries, benefits, incentive compensation, stock-based compensation, and travel, as well as consultant services, facilities, and other expenses, laboratory supplies and materials expenses for employees and contractors engaged in research and development. These expenses are exclusive of depreciation and amortization. We expense research and development costs as incurred in the period in which the underlying activity is undertaken.

We believe that our continued investment in research and development is essential to our long-term competitive position. We expect to continue to incur substantial research and development expenses as we invest in research and development to support our customers, develop new uses for our existing technology and develop improved and/or new offerings to our customers and partners. As a result, we expect that our research and development expenses will continue to increase in absolute dollars in future periods and vary from period to period as a percentage of revenue.

81

Table of Contents

Sales and Marketing

Our sales and marketing expenses consist primarily of salaries, commissions and other variable compensation, benefits, stock-based compensation and travel costs for employees within our commercial sales and marketing functions, as well as third-party costs associated with our marketing activities. These expenses are exclusive of depreciation and amortization.

We expect our sales and marketing expenses to increase in future periods as we expand our commercial sales, marketing and business development teams, increase our presence globally, and increase marketing activities to drive awareness and adoption of our products.

General and Administrative

General and administrative expenses primarily consist of salaries, benefits, stock-based compensation and travel costs for employees in our executive, accounting and finance, legal, corporate development, human resources, and office administration functions as well as professional services fees, such as consulting, audit, tax and legal fees, general corporate costs, facilities and allocated overhead expenses and costs associated with being a Nasdaq and AIM listed public company such as director fees, U.K. Nominated Advisor and broker fees, investor relations consultants and insurance costs. These expenses are exclusive of depreciation and amortization.

We expect that our general and administrative expenses will continue to increase in absolute dollars in future periods, primarily due to increased headcount to support anticipated growth in the business and due to incremental costs associated with operating as a public company listed on a U.S. exchange, including insurance (particularly directors and officers insurance), costs to comply with the rules and regulations applicable to companies listed on a U.S. securities exchange and costs related to compliance and reporting obligations pursuant to the rules and regulations of the SEC and stock exchange listing standards, investor relations and professional services. We expect these expenses to vary from period to period as a percentage of revenue.

Depreciation and Amortization

Depreciation expense consists of the depreciation of property and equipment used actively in the business, primarily by research and development activities. Amortization expense includes the amortization of leasehold improvements over their respective lease terms.

Other Income

Interest income includes interest earned on cash balances in our cash accounts and interest earned on money market funds, commercial paper and corporate bonds as well as miscellaneous income unrelated to our core operations.

Provision for Income Taxes

We did not recognize a benefit for the net operating losses we incurred for the years ended December 31, 2024 and 2023. As of December 31, 2024, we had U.S. net operating loss carryforwards of $109.9 million, which may be available to offset future taxable income and begin to expire in 2025, as well as net operating losses in the various states in which we file. We have recorded a full valuation allowance against our net deferred tax assets at each balance sheet date since, due to our history of net losses, we have determined that it is currently more likely than not that our net deferred tax assets are not recoverable.

Core revenue: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​

Total revenue for the year ended December 31, 2024 was $38.6 million, a decrease of $2.7 million, or 6%, compared to revenue of $41.3 million during the year ended December 31, 2023. The decrease was primarily driven by the decreases in program-related revenue.

Total core revenue for the year ended December 31, 2024 was $32.5 million, an increase of $2.7 million, or 9%, compared to core revenue of $29.8 million for the year ended December 31, 2023. Our overall increase in core revenue was primarily driven by revenue increases in PA and consumable sales, which increased by $3.7 million, or 36% for the year ended December 31, 2024 compared to the year ended December 31, 2023. The increase was also partially

attributable to an increase in other revenue of $0.2 million, offset by decreases in instrument sales of $1.2 million, for the year ended December 31, 2024 compared to the year ended December 31, 2023.

The $5.4 million decrease in SPL program-related revenues resulted from achievement of fewer contractually specified clinical and regulatory milestones during the year ended December 31, 2024 compared to the year ended December 31, 2023. The decrease reflects the expected variability from period to period in the level of program-related revenue given the small number of individual triggering events which currently generate this portion of revenue. We expect program-related revenue to continue to experience variability for some time, although we anticipate that variability may moderate as the volume of SPL agreements and associated milestones grows.

Cost of goods sold increased by $2.4 million, or 50%, for the year ended December 31, 2024, compared to the year ended December 31, 2023. The increase was primarily driven by increases in PA and consumable sales, an increase in the allowance for obsolete inventory of $1.1 million, and lower absorption of manufacturing overhead costs.

Gross profit decreased by $5.0 million, or 14%, for the year ended December 31, 2024, compared to the year ended December 31, 2023. The decrease was primarily driven by a decrease in program-related revenue for the year ended December 31, 2024 and by increases to cost of goods sold described above.

During the year ended December 31, 2024, gross margin was 82%, compared to 89% in the same period of 2023. The decrease was primarily driven by a decrease in SPL program-related revenue, and by an increase in the inventory allowance.

The decrease was primarily driven by a $1.6 million decrease in stock-based compensation, a $0.7 million decrease in engineering and lab expenses, and a $0.5 million decrease in office, travel, and general operating expenses, offset by a $0.6 million increase in occupancy expenses and a $0.6 million increase in compensation expenses.

Sales and marketing expenses decreased by $0.3 million, or 1%, for the year ended December 31, 2024, compared to the year ended December 31, 2023. The decrease was primarily driven by a $1.0 million decrease in occupancy expenses, a $0.4 million decrease in travel expenses, a $0.3 million decrease in stock-based compensation, and a $0.2 million decrease in professional services and marketing expenses, offset by a $1.4 million increase in compensation expense and a $0.2 million increase in software subscriptions.

(in thousands, except percentages) ​ ​ ​ ​

General and administrative expenses decreased by $0.4 million, or 1%, for the year ended December 31, 2024, compared to the year ended December 31, 2023. The decrease was primarily driven by a $1.4 million decrease in compensation expenses, a $0.8 million decrease in professional services, a $0.3 million credit loss recovery, net of expense, and a $0.2 million decrease in office, travel, and general operating expenses, offset by a $1.1 million increase in stock-based compensation, a $0.8 million increase in fixed asset disposal loss, and a $0.4 million increase in legal and public company expenses.

Depreciation and Amortization

​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​

​ ​ Year Ended December 31, ​ Change

(in thousands, except percentages) ​ ​ ​

Depreciation and amortization expense increased by $0.2 million, or 4%, for the year ended December 31, 2024, compared to the year ended December 31, 2023. The increase was primarily driven by investments in laboratory equipment and consignment instruments.

Other Income

​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​

​ ​ Year Ended December 31, ​ Change

(in thousands, except percentages) ​ ​ ​

Interest income decreased $0.2 million, or 2%, for the year ended December 31, 2024 compared to the year ended December 31, 2023. The decrease is primarily due to a decrease in balances of cash and investments.

Liquidity and Capital Resources

Since our inception, we have experienced losses and negative cash flows from operations. For the years ended December 31, 2024 and 2023, we incurred net losses of $41.1 million and $37.9 million, respectively. As of December 31, 2024, we had an accumulated deficit of $216.9 million. To date, we have funded our operations primarily with proceeds from sales of common stock, borrowings under loan agreements and cash flows associated with sales and licenses of our products to customers. On August 3, 2021, we completed our U.S. IPO, generating gross proceeds of $201.8 million. We received net proceeds of $184.3 million after deducting aggregate underwriting commissions and offering expenses of $17.6 million. As of December 31, 2024, we had cash and cash equivalents and short-term investments of $154.5 million.

85

Table of Contents

We expect to incur near-term operating losses as we continue to invest in expanding our business through growing our sales and marketing efforts, continued research and development, product development and expanding our product offerings. Based on our current business plan, we believe that our existing cash, cash equivalents, short-term investments and internally generated cash flows will enable us to fund our operating expenses and capital expenditure requirements for at least the next 12 months. We expect to end 2025 with approximately $160 million in total cash, cash equivalents and investments.

We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we expect. Our future funding requirements will depend on many factors, including:

• transaction and capital expenditures necessitated by strategic activities;

• market acceptance of our products;

• the effect of competing technological and market developments; and

• the level of our selling, general and administrative expenses.

If we are unable to execute on our business plan and adequately fund operations, or if the business plan requires a level of spending in excess of cash resources, we may have to seek additional equity or debt financing. If additional financings are required from outside sources, we may not be able to raise such capital on terms acceptable to us or at all. To the extent that we raise additional capital through the sale of equity or debt securities, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing, if available, may involve agreements that include covenants restricting our ability to take specific actions, such as incurring additional debt, selling or licensing our assets, making product acquisitions, making capital expenditures or declaring dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, it may be necessary to relinquish some rights to our technologies or our products, or grant licenses on terms that are not favorable to us. If we are unable to raise additional capital when desired, we may have to delay development or commercialization of future products. We also may have to reduce marketing, customer support or other resources devoted to our existing products.

Operating Activities

Net cash used in operating activities for the year ended December 31, 2024 was $27.6 million, and consisted primarily of our net loss of $41.1 million, offset in part by net non-cash expenses of $14.2 million, including stock-based compensation of $13.1 million, depreciation and amortization expenses of $4.3 million, an increase in our inventory reserve of $1.8 million, a loss on disposal of assets of $0.9 million, and other net non-cash expenses totaling $0.3 million, offset by the amortization of $6.2 million of discounts on investments. We also had net cash outflows of $0.7 million due to net changes in our operating assets and liabilities. Net changes in our operating assets and liabilities consisted primarily of a $1.9 million decrease in accounts payable, accrued expenses and other liabilities, a $1.2 million increase in other assets, and a $0.7 million decrease in operating lease liabilities, offset by a $1.4 million decrease in inventory, a $1.2 million decrease in accounts receivable, $0.3 million decrease in prepaid expenses and other current assets, and a $0.2 million increase in deferred revenue.

Net cash used in operating activities for the year ended December 31, 2023 was $21.7 million, and consisted primarily of our net loss of $37.9 million, offset in part by net non-cash expenses of $12.4 million, including stock-based compensation of $14.0 million, depreciation and amortization expenses of $4.2 million, an increase in our inventory reserve of $0.7 million, and other non-cash expenses totaling $0.6 million, offset by the amortization of $7.1 million of discounts on investments. We also had net cash inflows of $3.8 million due to net changes in our operating assets and liabilities. Net changes in our operating assets and liabilities consisted primarily of a $5.2 million decrease in accounts receivable, a $1.9 million decrease in tenant improvement allowances receivable, a $3.3 million increase in accounts payable, accrued expenses and other, and a $0.4 million decrease in other assets, offset by a $4.5 million increase in inventory, a $1.6 million decrease in deferred revenue, a $0.6 million decrease in prepaid expenses and other current assets, and a $0.2 million decrease in operating lease and other liabilities.

Investing Activities

Cash provided by investing activities during the year ended December 31, 2024 was $6.9 million, which was primarily attributable to maturities of investments of $159.4 million, partially offset by purchases investments of $150.9 million, and purchases of property and equipment of $1.7 million. Purchases of investments are made as part of ordinary course investing activities in compliance with our investment policy which has as its primary objective preservation of principal.

Cash provided by investing activities during the year ended December 31, 2023 was $55.0 million, which was primarily attributable to maturities of investments of $313.8 million, partially offset by purchases investments of $255.1 million, and purchases of property and equipment of $3.7 million.

Financing Activities

Net cash provided by financing activities during the years ended December 31, 2024 and 2023 was $2.1 million, which consisted of proceeds from the exercise of stock options and employee purchases from our employee stock purchase plan.

Contractual Obligations and Commitments

Our contractual obligations and commitments as of December 31, 2024 consisted exclusively of operating lease obligations. In May 2021, we entered into an operating lease for new office, lab and warehouse/manufacturing space (the “Headquarters Lease”). The Headquarters Lease term expires on August 31, 2035. The total incremental remaining non-cancellable lease payments under the lease agreement are $26.1 million through the lease term. We expect to be able to fund our obligations under this lease, both in the short-term and in the long-term, from cash on hand, investments and operating cash flows. See Part I, Item 2, “Facilities” in this Annual Report for additional information regarding the new office lease.

We had no debt obligations as of December 31, 2024 or 2023.

Purchase orders or contracts for the purchase of supplies and other goods and services are based on our current procurement or development needs and are generally fulfilled by our vendors within short time horizons.

Critical Accounting Estimates

We have prepared our consolidated financial statements in accordance with U.S. GAAP. Our preparation of these consolidated financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources.

Actual results could therefore differ materially from these estimates under different assumptions or conditions.

Critical accounting estimates are those estimates that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on our statement of operations and financial position. The following subset of our accounting estimates are considered to be our critical accounting estimates as of December 31, 2024 and 2023:

Allowance for Obsolete Inventory

We maintain an allowance for excess, obsolete, and slow-moving inventory to reflect the inventory at the lower of cost or net realizable value. These reserves are based on management's estimates of market conditions, future demand, and the physical condition of the inventory. Significant assumptions used in these estimates include historical sales trends, forecasted sales, and the expected timing of product obsolescence. Changes in these assumptions could materially affect the amounts reported in our financial statements. For the years ended December 31, 2024 and 2023, we recorded inventory reserves of $1.8 million and $0.7 million, respectively, primarily due to anticipated obsolescence and expiration of certain products.

Fair Value of Stock-based Compensation

We maintain an incentive compensation plan under which stock options and restricted stock units are granted primarily to employees, consultants and non-employee directors. We measure stock-based compensation expense on the date of grant and recognize the corresponding compensation expense of those awards over the requisite service period, which is generally the vesting period of the respective award. We record forfeitures as they occur.

We estimate the fair value of stock options granted to our employees and directors based on the closing price of our common stock on the grant date and the resulting stock-based compensation expense using the Black-Scholes option-pricing model. The fair value is based on the value of our common stock on the Nasdaq Global Select Market on the grant date. The Black-Scholes option-pricing model requires the use of assumptions regarding a number of variables that are complex, subjective and generally require significant judgment to determine. The assumptions include expected volatility based on the historical volatility of our common stock, expected dividend yield, risk-free rate of interest and the expected term using the simplified method and are disclosed in Note 4 to our consolidated financial statements.

Recent Accounting Pronouncements

A description of recently issued accounting pronouncements that may potentially impact our financial position, results of operations or cash flows is disclosed in Note 2 to our consolidated financial statements in this Annual Report.

Table of Contents

Emerging Growth Company Status

We are an “emerging growth company,” or EGC, under the JOBS Act. Section 107 of the JOBS Act provides that an EGC can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. Thus, an EGC can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to avail ourselves of the delayed adoption of new and revised accounting standards and, therefore, we will be subject to the same requirements to adopt new or revised accounting standards as private entities. We also intend to rely on other exemptions provided by the JOBS Act, including not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act.

We will remain an EGC until the earliest of: (i) December 31, 2026, which is the last day of the fiscal year following the fifth anniversary of our initial public offering in the United States; (ii) the last day of the first fiscal year in which our annual gross revenue is $1.235 billion or more; (iii) the date on which we have, during the previous rolling three-year period, issued more than $1 billion in non-convertible debt securities; and (iv) the last day of the fiscal year in which the market value of our common stock held by non-affiliates exceeded $700 million as of June 30 of such fiscal year.

We are also a “smaller reporting company,” as defined by Rule 12b-2 of the Exchange Act. We may continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250 million as of the last business day of our second fiscal quarter or (ii) our annual revenue is less than $100 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700 million as of the last business day of our second fiscal quarter. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company we have elected to present only the two most recent fiscal years of audited financial statements in this Annual Report. In addition, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

We are exposed to market risk for changes in interest rates related primarily to balances of our financial instruments including cash and cash equivalents and short-term investments. The primary objective of our investment approach is to preserve principal and provide liquidity. As a result, a 10% change in the level of market interest rates would not be expected to have a material effect on our business, financial condition or results of operations.

Foreign Currency Risk

We are exposed to financial risks as a result of exchange rate fluctuations between the U.S. Dollar and certain foreign currencies and the volatility of these rates. In the normal course of business, we earn revenue primarily denominated in U.S. Dollars as well as in Euros and British Pounds. We incur expenses primarily in U.S. Dollars as well as in Euros, British Pounds and other currencies. Our reporting currency is the U.S. Dollar. We hold our cash primarily in U.S. Dollars as well as in Euros and British Pounds. We do not expect that foreign currency gains or losses will have a material effect on our financial position or results of operations in the foreseeable future. We have not entered into any hedging arrangements with respect to foreign currency risk. As our international operations grow, we will continue to reassess our approach to managing risks relating to fluctuations in currency exchange rates.

Inflation Risk

During the last two years, inflation and changing prices have not had a material effect on our business. We are unable to predict whether inflation or changing prices will materially affect our business in the foreseeable future.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of MaxCyte, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of MaxCyte, Inc. (the “Company”) as of December 31, 2024 and 2023, and the related consolidated statements of operations, changes in stockholders’ equity, and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of their operations and their cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Notes to Consolidated Financial Statements

(in thousands, except par value, share and per share amounts)

1. Organization and Description of Business

MaxCyte, Inc. (the “Company” or “MaxCyte”) was incorporated as a majority owned subsidiary of EntreMed, Inc. (“EntreMed”) on July 31, 1998, under the laws and provisions of the state of Delaware and commenced operations on July 1, 1999. In November 2002, MaxCyte was recapitalized and EntreMed was no longer deemed to control the Company.

MaxCyte is a global life sciences company focused on advancing the discovery, development, and commercialization of next-generation cell therapies. MaxCyte leverages its proprietary cell engineering technology platform to enable the programs of its biotechnology and pharmaceutical company customers who are engaged in cell therapy, including gene editing and immuno-oncology, as well as in drug and biologic discovery and development and biomanufacturing. The Company licenses and sells its instruments and technology and sells its consumables to developers of cell therapies and to pharmaceutical and biotechnology companies for use in drug and biologic discovery and development and biomanufacturing.

The Company’s registration statement on Form S-1 related to its initial public offering of common stock in the United States (the “IPO”) was declared effective on July 29, 2021, and the Company’s common stock began trading on the Nasdaq Global Select Market on July 30, 2021. On August 3, 2021, the Company issued and sold 15,525,000 shares of common stock in the IPO at a price to the public of $13.00 per share, inclusive of 2,025,000 shares issued pursuant to the full exercise of the underwriters’ option to purchase additional shares. The IPO generated gross proceeds to the Company of $201,825. The Company received aggregate net proceeds of $184,268 from the IPO after deducting aggregate underwriting commissions and offering costs of $17,557.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”).

Use of Estimates

The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of revenues and expenses during the reporting period. In the accompanying consolidated financial statements, estimates are used for, but not limited to, revenue recognition, stock-based compensation, allowance for credit losses, allowance for inventory obsolescence, accruals for contingent liabilities, if applicable, deferred taxes and valuation allowance, and the depreciable lives of property and equipment. Actual results could differ from those estimates.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany balances have been eliminated in consolidation.

Reclassifications

Certain reclassifications have been made to prior years’ financial statements to conform to current year presentation. These reclassifications had no effect on previously reported results of operations or accumulated deficit.

96

Table of Contents

Concentrations of Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, investments and trade receivables. The Company’s cash and cash equivalents balances may exceed federally insured limits and cash may also be deposited in foreign bank accounts that are not covered by federal deposit insurance. The Company does not believe that this results in any significant credit risk. The Company invests its excess cash in money market funds, commercial paper and corporate debt. The Company has established guidelines relative to credit ratings, diversification and maturities that seek to maintain safety and liquidity.

Significant customers are those that accounted for 10% or more of the Company’s total revenue for the period or accounts receivable as the end of a reporting period. During the years ended December 31, 2024 and 2023, one customer represented 23% and 30% of revenue, respectively. As of December 31, 2024, this one customer accounted for 25% of accounts receivable, and another customer accounted for 14% of accounts receivable. As of December 31, 2023, three customers accounted for 38% of accounts receivable.

Certain components included in the Company’s products are obtained from a single source or a limited group of suppliers. During the year ended December 31, 2024, 16% of the Company’s additions to inventory were from one supplier. During the year ended December 31, 2023, the Company purchased approximately 56% from a single supplier. At December 31, 2024 and 2023, no supplier accounted for 10% or more of the Company’s total accounts payable.

Foreign Currency

The Company’s functional currency is the U.S. Dollar. Transactions denominated in foreign currencies are transacted at the exchange rate in effect at the date of each transaction. Differences in exchange rates during the period between the date a transaction denominated in foreign currency is consummated and the date on which it is either settled or at the reporting date are recognized in the consolidated statements of operations as general and administrative expense. For the years ended December 31, 2024 and 2023, the Company recognized $140 and $84 in foreign currency transaction losses, respectively.

Fair Value

Fair value is the price that would be received from the sale of an asset or paid to transfer a liability assuming an orderly transaction in the most advantageous market at the measurement date. US GAAP establishes a hierarchical disclosure framework which prioritizes and ranks the level of observability of inputs used in measuring fair value. These tiers include:

See Note 6 for additional information regarding fair value.

Cash and Cash Equivalents and Investments

Cash and cash equivalents consist of financial instruments including money market funds and commercial paper with original maturities of less than 90 days. Short-term investments consist of commercial paper, corporate bonds and U.S. Treasury securities and government agency bonds with original maturities greater than 90 days and less than one year. Long-term investments consist of U.S. Treasury securities and government agency bonds with maturities

97

Table of Contents

greater than one year. All money market funds and investments are recorded at amortized cost unless they are deemed to be impaired on an other-than-temporary basis, at which time they are recorded at fair value using Level 2 inputs. There were no changes from Level 2 for the years ended December 31, 2024 and 2023.

Inventory

The Company sells or licenses products to customers. The Company uses the average cost method of accounting for its inventory and adjustments resulting from periodic physical inventory counts are reflected in costs of goods sold in the period of the adjustment. Inventory is carried at the lower of cost or net realizable value. Inventory that is obsolete or in excess of forecasted usage is written down to its estimated net realizable value based on assumptions about future demand and market conditions. Inventory write-downs are charged to cost of goods sold and establish a new cost basis for the inventory.

Accounts Receivable

Accounts receivable are reduced by an allowance for expected credit losses if needed. The allowance for expected credit losses reflects the best estimate of probable losses determined principally on the basis of historical experience and specific allowances for known troubled accounts. All accounts or portions thereof that are deemed to be uncollectible or to require excessive collection effort are written off to the allowance for expected credit losses. The Company determined no allowance was necessary at December 31, 2024. The Company recorded an allowance for expected credit losses of $130 at December 31, 2023.

Property and Equipment

Property and equipment are stated at cost. Depreciation is computed using the straight-line method. Office equipment (principally computers) is depreciated over an estimated useful life of three years. Laboratory equipment is depreciated over an estimated useful life of five years. Furniture is depreciated over a useful life of five to seven years. Leasehold improvements are amortized over the shorter of the estimated lease term or useful life. Instruments represent equipment held at a customer’s site that is typically licensed to customers on a short-term basis and is depreciated over an estimated useful life of five years.

Property and equipment include capitalized costs to develop internal-use software. Applicable costs are capitalized during the development stage of the project and include direct internal costs, third-party costs and allocated interest expenses as appropriate.

Management reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of the long-lived asset is measured by a comparison of the carrying amount of the asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. The Company recognized no impairment for the years ended December 31, 2024 or 2023. The Company disposes of equipment when it has no future uses to the Company, and the loss on disposal is included in general and administrative expense in the Company’s consolidated statement of operations.

Revenue Recognition

The Company analyzes contracts to determine the appropriate revenue recognition using the following steps: (i) identification of contracts with customers; (ii) identification of distinct performance obligations in the contract; (iii) determination of contract transaction price; (iv) allocation of contract transaction price to the performance obligations; and (v) determination of revenue recognition based on timing of satisfaction of the performance obligations.

In some arrangements, product and services have been sold together representing distinct performance obligations. In such arrangements the Company allocates the sale price to the various performance obligations in the arrangement on a relative selling price basis. Under this basis, the Company determines the estimated selling price of each performance

obligation in a manner that is consistent with that used to determine the price to sell the deliverable on a standalone basis.

The Company recognizes revenue upon the satisfaction of its performance obligation (generally upon transfer of control of promised goods or services to its customers) in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services.

Licensing fee revenue is recognized ratably over the license period as a single performance obligation accounted under ASC 842, Leases. The single performance obligation consists of a lease of an instrument and license to intellectual property and technology that are integral to the instrument’s functionality, and therefore, all promises in a typical licensing arrangement of the Company are accounted for as a single performance obligation named “licenses” in our table of disaggregated revenue in Note 3.

Some licensing arrangements include provisions for milestone payments to the Company, if the customer accomplishes certain precommercial milestones in addition to the license of instrument and intellectual property. We refer to such licenses arrangements as strategic platform licenses (“SPLs”). We do not recognize revenue for the milestone provisions at the time of entering an SPL agreement, since each milestone stream of revenue is considered variable consideration that is highly uncertain and susceptible to factors outside our influence. We recognize the amount of revenue related to each milestone only at the time our customer achieves the milestone.

The Company defers incremental costs of obtaining a customer contract and amortizes the deferred costs over the period that the goods and services are transferred to the customer. The Company had no material incremental costs to obtain customer contracts in any period presented.

Deferred revenue results from amounts billed in advance to customers or cash received from customers in advance of services being provided.

Cost of Goods Sold

Cost of goods sold primarily consists of costs for raw material parts, contract manufacturer costs, salaries, overhead, licensed equipment depreciation and other direct costs related to sales recognized as revenue in the period.

Research and Development Costs

Research and development costs consist of independent proprietary research and development costs and the costs associated with work performed for fees from third parties. Research and development costs are expensed as incurred. Research costs performed for fees paid by customers are included in cost of goods sold.

Stock-Based Compensation Expense

Stock-based compensation expense is measured based on grant-date fair value. The Company grants stock-based awards in exchange for employee, consultant and non-employee director services. The value of the award is recognized as expense on a straight-line basis over the requisite service period.

The Company uses the market closing price of its common stock as reported on the Nasdaq Global Select Market for the fair value of equity awards on the grant date. The grant-date fair value of stock options is estimated using the Black-Scholes option pricing model for estimating fair value of its stock options granted. Option valuation models, including the Black-Scholes option pricing model, require the input of highly subjective assumptions, and changes in the assumptions used can materially affect the grant-date fair value of an award. These assumptions include the expected volatility, expected dividend yield, risk-free rate of interest and the expected life of the award. The Company has observed sufficient historical information regarding its common stock to use the Company’s common stock for the estimate of volatility in the Black-Scholes option pricing model. Management’s methodology for developing other

99

Table of Contents

assumptions has not changed from prior periods. A discussion of management’s methodology for developing each of the assumptions used in the Black-Scholes option pricing model is as follows:

Expected Volatility

Volatility is a measure of the amount by which a financial variable such as a share price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. The Company estimates its expected stock volatility based on historical volatility of its own common stock.

Expected Dividend Yield

The Company has never declared or paid common stock dividends and has no plans to do so in the foreseeable future. Therefore, the Company used an expected dividend yield of zero.

Risk-Free Interest Rate

This approximates the U.S. Treasury rate for the day of each option grant during the year, having a term that closely resembles the expected term of the option. For the Employee Stock Purchase Plan (“ESPP”), the U.S. Treasury rate on each Offering Date is used for a term that approximates the Purchase Period.

Expected Term

This is the period that the options granted are expected to remain unexercised. Options granted have a maximum term of ten years. The Company estimates the expected term of the options to be approximately six years for options, with a majority vesting over a four-year period, using the simplified method. Over time, management intends to track estimates of the expected term of the option term so that estimates will approximate actual behavior for similar options. For the ESPP, the term of each Purchase Period is used.

Expected Forfeiture Rate

The Company records forfeitures as they occur.

The fair value of stock options was estimated using the Black-Scholes option-pricing model based on the following assumptions during the years ended:

​ ​ ​ ​ ​ ​

​ ​ December 31,

Risk-free interest rate ​ 3.4-4.5% ​ 3.3-4.6% ​

Expected term (in years) ​ 5.5-6.1 ​ 3.6-6.1 ​

The fair value of the shares under the ESPP was estimated using the Black-Scholes option-pricing model based on the following assumptions during the years ended:

​ ​ ​ ​ ​

​ ​ December 31,

Expected volatility ​ 55% ​ 57-60%

Expected term (in years) ​ 0.5 ​ 0.5

See Note 4 for additional information regarding stock-based compensation.

Income Taxes

The Company uses the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that such tax rate changes are enacted. The measurement of a deferred tax asset is reduced, if necessary, by a valuation allowance if it is more-likely-than-not that all or a portion of the deferred tax asset will not be realized.

Management uses a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return, as well as guidance on derecognition, classification, interest and penalties and financial statement reporting disclosures. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company recognizes interest and penalties accrued on any unrecognized tax exposures as a component of income tax expense. The Company has not identified any uncertain income tax positions that could have a material impact on the consolidated financial statements.

The Company is subject to taxation in various jurisdictions in the United States and abroad and remains subject to examination by taxing jurisdictions for 2020 and all subsequent periods. The Company has a federal Net Operating Loss (“NOL”) carryforward of approximately $109.9 million as of December 31, 2024, of which approximately $32.7 million begins to expire in 2025. Certain of the Company’s NOLs were initially limited on an annual basis pursuant to Section 382 of the Internal Revenue Code of 1986 (“Section 382”), as amended, as a result of a cumulative change in ownership that occurred in 2016; however, as of December 31, 2024, the Company has determined that the cumulative limitation amount exceeds the NOLs subject to the limitation and, as a result, no annual limitation remains.

Leases

Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. In transactions where the Company is the lessee, at the inception of a contract, the Company determines if the arrangement is, or contains, a lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Lease expense is recognized on a straight-line basis over the lease term.

The Company has made certain accounting policy elections for leases where it is the lessee whereby the Company (i) does not recognize ROU assets or lease liabilities for short-term leases (those with original terms of 12 months or less) and (ii) combines lease and non-lease elements of its operating leases. See Note 8 for additional details about leases where the Company is the lessee.

All transactions in which the Company is the lessor are short-term (one year or less) and have been classified as operating leases. All leases require upfront payments covering the full period of the lease and thus, there are no future payments expected to be received from existing leases. See Note 3 for details about revenue recognition related to license agreements.

Comprehensive Loss

For the years ended December 31, 2024 and 2023, comprehensive loss equaled net loss; therefore, a separate statement of comprehensive loss is not included in the accompanying consolidated financial statements.

Loss Per Share

Basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of Common Stock outstanding during the period.

101

Table of Contents

For periods of net income, and when the effects are not anti-dilutive, diluted earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of shares outstanding plus the impact of all potential dilutive common shares, consisting primarily of common stock options and stock purchase warrants using the treasury stock method.

For periods of net loss, diluted loss per share is calculated similarly to basic loss per share because the impact of all dilutive potential common shares is anti-dilutive. The number of anti-dilutive shares, consisting of stock options and restricted stock units excluded from the computation of diluted loss per share, was 16.3 million and 16.7 million for the years ended December 31, 2024 and 2023, respectively.

Recent Accounting Pronouncements

New Accounting Pronouncements Recently Adopted

In December 2024, the Company adopted Accounting Standard Update ("ASU") 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, effective November 27, 2023. This guidance amends Topic 280 to require disclosure of significant segment expenses and other segment items on an annual and interim basis and to provide in interim periods all disclosures about a reportable segment's profit or loss and assets that are currently required annually. The adoption of this guidance did not have a material impact on the Company’s financial statements. See Note 10-Segment Reporting” for additional information.

New Accounting Pronouncements Not Yet Adopted

In December 2023, the FASB issuedASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU amends the guidance in Accounting Standards Codification (“ASC’) 740, Income Taxes, to improve the transparency of income tax disclosures by amending the required rate reconciliation disclosures as well as requiring disclosure of income taxes paid disaggregated by jurisdiction. The rate reconciliation disclosure will be required to be presented in both percentages and reporting currency amounts, with greater disaggregation of information. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024 and should be applied prospectively, with early adoption permitted. The Company is currently evaluating the amendments to identify potential impacts to the Company’s income tax disclosures beginning with the Annual Report on Form 10-K for the year ended December 31, 2025 on a prospective basis.

In November 2024, the FASB issued Accounting Standard Update No. 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures” (“ASU 2024-03”). The amendments in ASU 2024-03 improve the transparency of expenses by nature disclosures requiring disclosures disaggregating of each expense line item into specific categories, and qualitative disclosures of expenses. ASU 2024-03 will be effective for the fiscal years beginning after December 31, 2026. The Company is in the process of evaluating the impact of this ASU on its consolidated financial statements.

3. Revenue

Revenue is principally from the sale of instruments, processing assemblies (“PAs”) and consumables, and extended warranties and from our license agreements, which also include customer-specific milestone payments. In some arrangements, product and services have been sold together representing distinct performance obligations. In these arrangements the Company allocates the sale price to the various performance obligations in the arrangement on a relative selling price basis. Under this basis, the Company determines the estimated selling price of each performance obligation in a manner that is consistent with that used to determine the price to sell the deliverable on a standalone basis.

Revenue is recognized at the time control is transferred to the customer and the performance obligation is satisfied. Revenue from the sale of instruments, PAs and consumables is generally recognized at the time of shipment to the customer, provided no significant vendor obligations remain and collectability is reasonably assured. Revenue from licenses is recognized ratably over the license term and when specific milestones are achieved by a customer. Licensing

Performance Stock Units (“PSUs”)

During the year ended December 31, 2024, 550,838 PSUs were awarded to certain members of management and executive officers. The PSU awards represent a number of shares of common stock to be earned if a target level of performance, as approved by the Board of Directors, is achieved. The performance period continues through December 31, 2026. The actual number of shares of common stock underlying the PSUs to be earned will be between 0% and 125% of the target number of PSUs, depending on the level of achievement of such performance metrics. The weighted-average fair value of the PSUs granted during the year ended December 31, 2024 was estimated to be $4.31 per PSU. As of December 31, 2024, the Company determined that it was probable that the grants will vest at 100% of the target number of PSUs. During the year ended December 31, 2024, the Company recognized $794 in compensation expense related to the PSUs. The Company did not issue PSUs prior to January 2024. As of December 31, 2024, total unrecognized compensation expense related to outstanding PSUs was $1,581, which will be recognized over the next 2.0 years.
