Notes to Condensed Consolidated Financial Statements

(Unaudited)

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 discovery and development and biomanufacturing. The Company licenses and sells its instruments and technology and sells its consumables to developers of cell therapies and pharmaceutical and biotechnology companies for use in drug 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 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 unaudited condensed consolidated interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the instructions to Form 10-Q and Article 8 of Regulation S-X of the United States Securities and Exchange Commission (the “SEC”). In the Company’s opinion, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly the financial position, results of operations, and cash flows as of and for the periods presented. The condensed consolidated balance sheet at December 31, 2023 has been derived from audited consolidated financial statements as of that date. The unaudited condensed consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year or any other future year or period. Certain information and notes disclosure normally included in financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to instructions, rules, and regulations prescribed by the SEC. The Company believes that the disclosures provided herein are adequate to make the information presented not misleading when these unaudited interim condensed consolidated financial statements are read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K filed with the SEC on March 12, 2024.

Significant Accounting Policies

The Company’s significant accounting policies are disclosed in the notes to its audited consolidated financial statements for the year ended December 31, 2023 included in its Annual Report on Form 10-K and have not materially changed during the three months ended March 31, 2024.

7

Basis of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, CCTI, Inc. 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.

Concentration of Risk

The Company maintains its cash and cash equivalents with three financial institutions that management believes to be of high credit quality. At times, the Company’s cash 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 beyond the normal credit risk associated with commercial banking relationships.

Significant customers are those that accounted for 10% or more of the Company’s total revenue for the period or accounts receivable as of the end of a reporting period. During the three months ended March 31, 2024, two customers represented 23% and 18% of revenue, respectively. During the three months ended March 31, 2023, two customers represented 23% and 11% of revenue, respectively. As of March 31, 2024, two customers accounted for 23% 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 three months ended March 31, 2024, 30% of the Company’s additions to inventory was from one supplier. During the three months ended March 31, 2023, the Company purchased 60% of its inventory from one supplier. As of March 31, 2024, amounts payable to one supplier totaled 29% of total accounts payable.  At December 31, 2023, no supplier accounted for 10% or more of the Company’s total accounts payable.  

Accounts Receivable

Accounts receivable are reduced by an allowance for credit losses, if needed. The Company maintains an allowance for credit losses of an amount equal to anticipated future write-offs. The Company determined that no allowance was necessary at March 31, 2024.  The Company recorded an allowance for expected credit losses of $130 at December 31, 2023.

Foreign Currency

The Company’s functional currency is the US dollar; transactions denominated in foreign currencies are subject to currency risk. The Company recognized $33 in foreign currency transaction losses and $6 in foreign currency transaction gains for the three months ended March 31, 2024 and 2023, respectively.  

Leases

For transactions in which the Company is the lessee, at the inception of a contract, the Company determines if the arrangement is, or contains, a lease. See Note 7 for additional details about leases under which 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 on revenue recognition related to lease agreements.

Comprehensive Loss

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

8

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.

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, restricted stock units, performance stock units and shares under employee stock purchase plans 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 excluded from the computation of diluted loss per share, consisting of shares underlying stock options, restricted stock units, performance stock units, and shares under employee stock purchase plans was 17.9 million for the three months ended March 31, 2024 and 17.1 million for the three months ended March 31, 2023.

Recent Accounting Pronouncements

The Company has evaluated all issued and unadopted Accounting Standards Updates and believes the adoption of these standards will not have a material impact on its results of operations, financial position, or cash flows.

3.    Revenue

Revenue is principally from the sale of instruments and processing assemblies, extended warranties and the lease of instruments, which lease agreements also include customer-specific milestone payments. In some arrangements, products 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 and processing assemblies is generally recognized at the time of shipment to the customer, provided that no significant vendor obligations remain and collectability is reasonably assured. Revenue from equipment leases is recognized ratably over the contractual term of the lease agreement and when specific milestones are achieved by a customer. Licensing fee revenue is recognized ratably over the license period. Revenue from fees for research services is recognized when services have been provided.

Disaggregation of Revenue

The following table depicts the disaggregation of revenue by type of contract:

		Three months ended March 31, 2024

Additional Disclosures Relating to Revenue from Contracts with Customers

Deferred revenue represents payments received for performance obligations not yet satisfied and is presented as current or long-term in the accompanying condensed consolidated balance sheets based on the expected timing and satisfaction of the underlying goods or services. Deferred revenue was $4,755 and $5,352 as of March 31, 2024 and December 31, 2023, respectively. During the three months ended March 31, 2024 and March 31, 2023, the Company recognized $2,254 and $2,623 of revenue, respectively, that was included in deferred revenue at the beginning of such periods.

Remaining contract consideration for which revenue has not been recognized due to unsatisfied performance obligations with a duration greater than one year at March 31, 2024 was $360, of which the Company expects to recognize $81 in one year or less, $81 in one to two years, $41 in two to three years, and $157 thereafter.

For the three months ended March 31, 2024 and 2023, the Company did not incur, and therefore did not defer, any material incremental costs to obtain contracts or costs to fulfill contracts.

4.    Stockholders’ Equity

Common Stock

During the three months ended March 31, 2024, the Company issued 272,640 shares of common stock as a result of stock option exercises, receiving gross proceeds of $703, and issued 170,801 shares from the vesting of restricted stock units.

Preferred Stock

The Company’s certificate of incorporation authorizes the issuance of up to 5,000,000 shares of preferred stock, par value $0.01 per share. As of March 31, 2024 and December 31, 2023, no shares of preferred stock were issued or outstanding.

Stock Incentive Plans

The Company adopted the MaxCyte, Inc. Long-Term Incentive Plan (the “2016 Plan”) in January 2016 to provide for the awarding of (i) stock options, (ii) restricted stock, (iii) incentive shares, and (iv) performance awards, in each case, to employees, officers, and directors of the Company and to other individuals as determined by the Board of Directors.

In December 2021, the Company adopted the MaxCyte, Inc. 2021 Inducement Plan (the “Inducement Plan”) to provide for the awarding of (i) non-qualified stock options; (ii) stock appreciation rights; (iii) restricted stock awards; (iv) restricted stock unit awards; (v) performance awards; and (vi) other awards, in each case, only to persons eligible to receive grants of awards who satisfy the standards for inducement grants under Nasdaq Marketplace Rule 5635(c)(4) or 5635(c)(3), if applicable, and the related guidance under Nasdaq IM 5635-1. The Board of Directors reserved 2,500,000 shares for issuance under the Inducement Plan.

In May 2022, the Company’s Board of Directors adopted, and in June 2022, the Company’s stockholders approved, the MaxCyte, Inc. 2022 Equity Incentive Plan (the “2022 Plan”) to provide for the awarding of (i) incentive stock options, (ii) non-qualified stock options, (iii) stock appreciation rights, (iv) restricted stock awards, (v) restricted stock unit awards, (vi) performance awards, and (vii) other awards. Following the approval of the 2022 Plan, no additional awards can be

10

granted under the 2016 Plan or the Inducement Plan, but all outstanding awards will continue to remain subject to the terms of the applicable plan.

Upon the effectiveness of the 2022 Plan, a total of 3,692,397 shares were initially reserved for issuance pursuant to future awards under the 2022 Plan, consisting of 1,928,000 new shares and 1,764,397 shares previously available under the 2016 Plan. If and to the extent that outstanding options under the 2016 Plan or the Inducement Plan are forfeited, the shares underlying such forfeited options will become available for issuance under the 2022 Plan. At the Company’s Annual Meeting of Stockholders held on June 22, 2023, the Company’s stockholders voted to reserve an additional 6,069,000 shares of issuance pursuant to future awards under the 2022 Plan.

At March 31, 2024 and December 31, 2023, there were 4,353,000 and 6,202,000 shares, respectively, available to be issued under the 2022 Plan.

The value of an equity award is recognized as expense on a straight-line basis over the requisite service period. At March 31, 2024, total unrecognized compensation expense was $25,434, which will be recognized over an estimated weighted average period of 2.6 years.

Stock Options

The weighted-average fair value of the stock options granted during the three months ended March 31, 2024 and 2023 was estimated to be $2.23 and $2.04, per option share, respectively.  

Restricted Stock Units (“RSUs”)

The weighted-average fair value of the RSUs granted during the three months ended March 31, 2024 and 2023 was estimated to be $4.36 and $4.35 per RSU, respectively.

Performance Stock Units (“PSUs”)

During the three months ended March 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 three months ended March 31, 2024 was estimated to be $4.31 per PSU. During the three months ended March 31, 2024, the Company determined that it was probable that the grants will vest at 100% of the target number of PSUs.  Stock-based compensation expense for the service period since the grant date of $197 was recognized in the three months ended March 31, 2024.  The Company did not issue PSUs prior to January 2024.

Stock-based Compensation Expense

The Company recorded stock-based compensation expense in the following expense categories of its condensed consolidated statements of operations:

	Three months ended March 31,
	2024		2023

6.    Fair Value

The Company’s condensed consolidated balance sheets include various financial instruments (primarily cash and cash equivalents, accounts receivable and accounts payable) that are carried at cost, which approximates fair value due to the short-term nature of the instruments.

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Company had no financial assets or liabilities measured at fair value on a recurring basis as of March 31, 2024 or December 31, 2023.

Financial Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

Money market funds, US Treasury securities and government agency bonds, commercial paper and corporate debt instruments classified as held-to-maturity are measured at fair value on a non-recurring basis when they are deemed to be impaired on an other-than-temporary basis. The Company periodically reviews investments to assess for credit impairment. Based on its assessment, all unrecognized holding losses were due to factors other than credit loss, such as changes in interest rates. Therefore, no impairment was recognized during the three months ended March 31, 2024 or 2023.

The following table summarizes the Company’s financial instruments that were measured at fair value on a non-recurring basis at March 31, 2024:

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 including cell and gene therapies 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 is used by biopharmaceutical companies to facilitate 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 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. Our disposables and consumables include processing assemblies (“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 and biologic developers and top biopharmaceutical companies to top academic and government research institutions, including the U.S. National Institutes of Health, 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, which includes but is not limited to our 27 SPL partners, ranges from large biopharmaceutical companies, including a majority of the top 25 pharmaceutical companies based on 2022 global revenue, to hundreds of biotechnology companies and academic centers focused on translational research.  Our Flow Electroporation technology is used by one of our SPL partners to engineer the first ex-vivo cell therapy approved by the FDA in December 2023.

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, commercialization adoption and market acceptance of our products. We generated revenue of $11.3 million and incurred a net loss of $9.5 million for the three months ended March 31, 2024. As of March 31, 2024, we had an accumulated deficit of $185.3 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 force, scaling our manufacturing operations, continuing research and development efforts to develop new products and further enhance our existing products.

18

Recent Developments

Throughout the first quarter of 2024, we have continued to enter into SPL agreements with our cell therapy customers. These agreements, which are discussed in more detail in “Results of Operations” below, provide us with revenue from instrument sales and leases and disposables sales as well as pre-commercial milestones based on progress of our partners’ programs through the clinic and sales-based payments upon commercialization of our partners’ programs. In the first quarter of 2024, we signed SPL agreements with three new partners: Lion TCR, Imugene, Wugen, and we announced that we had signed a fourth agreement with Be Biopharma on April 2, 2024.  We continue to grow our SPL pipeline and, while the specific timing of any agreement is uncertain, we look forward to continuing to build on our existing SPL partnerships and develop additional SPL partnerships in the future.

Revenue

We generate revenue principally from the sale of instruments and single-use PAs and buffer, and from the lease of instruments to our customers. Our SPL partnerships also include associated clinical progress milestones and sales-based payments to us, in addition to annual lease payments.

In order to evaluate how our sales are trending across key markets, as well as the contribution of program-related revenue from our SPL partnerships, we separately analyze revenue derived from our cell therapy customers and drug discovery customers, as well as the performance-based milestone revenues we recognize under our SPL partnerships. Cell therapy revenues include primarily revenue from instruments sold, annual license fees for instruments under lease, and sales of our proprietary disposables. Drug discovery revenue includes primarily revenue from instruments sold, sales of our proprietary disposables and, occasionally, instruments leased. Core revenue includes sales and leases of instruments and disposables to cell therapy and drug discovery customers, excluding SPL program-related revenue. Program-related revenues include clinical progress milestone and sales-based revenues derived from SPL agreements. Milestone revenues are recognized when a customer achieves the associated milestone event.

The following table provides details regarding our core business revenue for the periods presented:

	Three Months Ended

	2024		2023		Amount		%
(in thousands, except percentages)
Core revenue:
Instrument revenue	$	1,928	$	2,189	$	(261)	(12%)

Other revenue		224		174		50	29%
Total core revenue	$	8,188	$	7,772	$	416	5%

Total revenue for the three months ended March 31, 2024 was $11.3 million, an increase of $2.8 million, or 32%, compared to revenue of $8.6 million during the three months ended March 31, 2023.  The increase was primarily driven by an increase in program-related revenue and total core revenue described below.

Total core revenue for the three months ended March 31, 2024 was $8.2 million, an increase of $0.4 million, or 5%, compared to core revenue of $7.8 million for the three months ended March 31, 2023.  Our overall increase in core revenue was primarily driven by increases in disposable sales of $0.8 million in the cell therapy market and drug discovery markets, primarily offset by decreases in instrument sales and lease revenue of $0.3 million and $0.2 million, respectively.  

The $2.4 million increase in program-related revenues resulted from achievement of contractually specified clinical and regulatory milestones and 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 partnerships and associated milestones grows.

We expect total revenue to increase over time as our customers’ programs advance and our markets grow, resulting in additional instrument sales and leases and disposable sales and as the percentage of our installed base that are under cell therapy license agreements increases. We expect revenue from disposable and instrument sales and instrument licenses to cell therapy customers will continue to grow as those customers advance their preclinical pipeline programs into clinical development and move their existing drug development programs into later-stage clinical trials and, potentially, into commercialization. In addition, we believe we are well positioned to attract new customers who may contribute to these revenues, based on the underlying growth in the cell therapy pipeline among companies in this market, the extent to which capital is available to support such companies, and in particular the switch by some cell therapy companies away from viral to non-viral approaches. We expect, however, that our revenue may fluctuate from period to period due to the timing of securing product sales and licenses, the inherently uncertain nature of the timing of our partners’ achievements of clinical progress and our dependence on the program decisions of our partners.

20

Cost of Goods Sold and Gross Profit

Cost of goods sold primarily consists of costs for instrument and processing assembly components, contract manufacturer costs, salaries, overhead and other direct costs related to sales recognized as revenue in the period. Cost of goods sold associated with instrument lease revenue consists of leased equipment depreciation. Gross profit is calculated as revenue less cost of goods sold. Gross profit 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, disposables and milestones, the specific mix among types of instruments or disposables, the proportion of revenues associated with instrument leases as opposed to sales, 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, and the pricing of our products which may be impacted by market conditions.

During the three months ended March 31, 2024 and 2023, gross margin remained flat at 88%.  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. Instrument pricing also depends upon the customer’s specific market. However, the market for non-viral delivery is highly competitive, and introduction of a GMP-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 negatively impacts our gross margins.

	Three Months Ended March 31,				Change
	2024		2023		Amount		%
(in thousands, except percentages)
Cost of goods sold	$	1,403	$	1,000	$	403	40%
Gross profit	$	9,939	$	7,576	$	2,363	31%
Gross margin		88%		88%

Cost of goods sold increased by $0.4 million, or 40%, for the three months ended March 31, 2024 compared to the three months ended March 31, 2023. The increase was primarily driven by an increase in disposable sales and in-house manufacturing and raw material pricing increases, offset by a decrease in instrument sales.

Gross profit increased by $2.4 million, or 31%, for the three months ended March 31, 2024 compared to the three months ended March 31, 2023. The increase was primarily driven by an increase in program-related revenue for the three months ended March 31, 2024.  

We expect that our cost of goods sold will generally increase or decrease modestly as our instrument and disposables revenue increases or decreases. We expect our gross margin to benefit from realization of program-related revenue from our SPL agreements, to the extent that such revenue grows to be a significant proportion of overall revenues, as there is no cost of goods sold associated with such revenue. However, realization and timing of these potential milestone revenues is uncertain.

Operating Expenses

Research and Development

	Three Months Ended March 31,				Change
	2024		2023		Amount		%
(in thousands, except percentages)
Research and development	$	6,678	$	6,047		$631	10%

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 disposables, including hardware and software engineering) and design and other costs not directly charged to inventory or cost of goods sold.

21

These expenses principally include employee-related costs, such as salaries, benefits, incentive compensation, stock-based compensation, and travel, as well as consultant services, facilities, and laboratory supplies and materials. 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.

Research and development expenses increased by $0.6 million, or 10%, for the three months ended March 31, 2024 compared to the three months ended March 31, 2023. The increase was primarily driven by a $0.8 million increase in compensation expense and a $0.2 million increase in lab expense, offset by a $0.4 million decrease in stock-based compensation.

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 for 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.  

Sales and Marketing

	Three Months Ended March 31,				Change
	2024		2023		Amount		%
(in thousands, except percentages)
Sales and marketing	$	7,365	$	6,296	$	1,069	17%

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.

Sales and marketing expenses increased by $1.1 million, or 17%, for the three months ended March 31, 2024 compared to the three months ended March 31, 2023. The increase was primarily driven by a $0.7 million increase in compensation expenses as a result of increases in headcount, and a $0.4 million increase in professional fees.

We expect our recurring sales and marketing expenses to increase in absolute dollars in future periods as we expand our commercial sales, marketing and business development teams, expand our product offerings, expand our collaboration efforts, increase our presence globally, and increase marketing activities to drive awareness and adoption of our products. We expect that in the near term, sales and marketing expenses could increase as a percentage of revenue, and thereafter vary from period to period as a percentage of revenue.  The effects of such sales and marketing investments could take a few quarters to materialize into revenue growth or it may not materialize into revenue growth as expected or at all.

General and Administrative

	Three Months Ended March 31,				Change
	2024		2023		Amount		%
(in thousands, except percentages)
General and administrative	$	7,103	$	7,499	$	(396)	(5)%

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, information systems 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 public company fees associated with being a Nasdaq and AIM listed public company such as director fees, U.K. Nominated Adviser and broker fees, investor relations consultants fees and insurance costs. These expenses are exclusive of depreciation and amortization.

General and administrative expenses decreased by $0.4 million, or 5%, for the three months ended March 31, 2024 compared to the three months ended March 31, 2023. The decrease was primarily driven by a $0.5 million decrease in

22

professional services, an aggregate $0.2 million decrease in occupancy and general office expenses, offset by an increase in stock-based compensation of $0.2 million, an increase of $0.1 million in public company fees.

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. 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 intangible assets over their respective useful lives.

Depreciation and amortization expense increased by $0.2 million, or 17%, for the three months ended March 31, 2024, compared to the three months ended March 31, 2023. The increase was primarily driven by increases in leasehold improvements and purchases in laboratory equipment.

Interest Income and Other Expense

	Three Months Ended March 31,				Change
	2024		2023		Amount		%
(in thousands, except percentages)
Interest income	$	2,749		2,296	$	453	20%

Interest income represents interest on our cash balances and investments, which increased by $0.5 million, or 20%, for the three months ended March 31, 2024 compared to March 31, 2023. The increase was driven by increases in interest rates during the three months ended March 31, 2024.

Liquidity and Capital Resources

Since our inception, we have experienced losses and negative cash flows from operations. For the three months ended March 31, 2024, we incurred a net loss of $9.5 million. As of March 31, 2024, we had an accumulated deficit of $185.3 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.

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 from the date these financial statements have been issued.

23

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 cost and timing of establishing additional sales, marketing and distribution capabilities;

• the cost of our research and development activities and successful development of data supporting use of our products for new applications, and timely launch of new features and products;

• sales to existing and new customers and the progress of our SPL partners in developing their pipelines of product candidates;

• our ability to enter into additional SPL partnerships and licenses for clinical use of our platform in the future;

• changes in the amount of capital available to existing and emerging customers in our target markets;

• 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 three months ended March 31, 2024 was $10.6 million, and consisted primarily of our net loss of $9.5 million, offset in part by net non-cash expenses of $2.4 million, including stock-based compensation of $3.0 million, depreciation and amortization expenses of $1.1 million, and an aggregate $0.2 million in bad debt recoveries and other non-cash charges offset by amortization of discounts on investments of $2.0 million. We also had net cash outflows of $3.4 million due to changes in our operating assets and liabilities. Net changes in our operating assets and liabilities consisted primarily of an increase in accounts receivable of $0.3 million, a decrease in accounts payable and accrued expenses of $3.3 million due to timing considerations, a decrease in deferred revenue of $0.6 million, and a decrease in operating lease liabilities of $0.1 million, offset by a decrease in prepaid expenses and other current assets of $0.7 million and a decrease in inventory of $0.2 million.  

Net cash used in operating activities for the three months ended March 31, 2023 was $4.3 million, and consisted primarily of our net loss of $10.9 million, offset in part by net non-cash expenses of $2.6 million, including stock-based compensation of $3.3 million and depreciation and amortization expenses of $1.0 million, and other non-cash charges of $0.1 million, offset by amortization of discounts on investments of $1.7 million. We also had net cash inflows of $3.9 million due to changes in our operating assets and liabilities. Net changes in our operating assets and liabilities consisted primarily of a decrease in accounts receivable of $3.4 million due to increased cash collections, an increase in accounts payable and accrued expenses of $1.2 million due to timing considerations, a decrease in tenant improvements allowance (“TIA”) receivable of $0.9 million, a decrease in prepaid expense and other current assets of $0.5 million, and a decrease in other assets of $0.4 million, partially offset by a $1.7 million increase in inventory and a $1.0 million increase in deferred revenue.

Investing Activities

Net cash used in investing activities during the three months ended March 31, 2024 was $14.4 million, which was primarily due to purchases of investments of $48.0 million and purchases of property and equipment of $0.8 million, offset by maturities of investments of $34.4 million.

Net cash provided by investing activities during the three months ended March 31, 2023 was $29.6 million, which was primarily attributable to maturities of investments of $89.0 million, partially offset by purchases of investments of $57.8 million and purchases of property and equipment of $1.6 million.

Financing Activities

Net cash provided by financing activities during the three months ended March 31, 2024 and 2023 was $0.7 million, and $1.5 million, respectively, which was attributable to the exercise of stock options.

Contractual Obligations and Commitments

Our contractual obligations and commitments as of March 31, 2024 consisted exclusively of operating lease obligations. In May 2021, we entered into the Headquarters Lease for new office, lab and warehouse/manufacturing space. The Headquarters Lease term expires on August 31, 2035. The total incremental remaining non-cancellable lease payments under the lease agreement are $27.7 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.

We had no debt obligations as of March 31, 2024 and December 31, 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.

25

Critical Accounting Estimates

We have prepared our condensed consolidated financial statements in accordance with U.S. GAAP. Our preparation of these condensed 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.

There have been no material changes to our critical accounting policies and estimates from those disclosed in our consolidated financial statements and the related notes and other financial information included in the Annual Report on Form 10-K filed with SEC on March 12, 2024.

JOBS Act Accounting Election

We are an emerging growth company, (“EGC”), under the Jumpstart Our Business Startups Act of 2012, (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.

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 condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

Item 3. 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 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.

26

As we do not currently have indebtedness, we are not exposed to interest rate risk from increases in interest rates.

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 assess 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.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our “disclosure controls and procedures” as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the design and operation of these disclosure controls and procedures were effective as of March 31, 2024 at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the three months ended March 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

27

PART II. OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, we may become involved in legal proceedings arising in the ordinary course of our business. We are not currently a party to any material legal proceedings, and we are not aware of any pending or threatened legal proceeding against us that we believe will have, individually or in the aggregate, a material adverse effect on our business, financial condition or results of operations.

Item 1A. Risk Factors.

Our business is subject to risks and events that, if they occur, could adversely affect our financial condition and results of operations and the trading price of our securities. In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors described in Part I, Item 1A. “Risk Factors” of our Annual Report on Form 10-K filed with the SEC on March 12, 2024. There have been no material changes to the risk factors set forth in that report.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

(a) Sale of Unregistered Securities

None.

(b) Use of Proceeds

Cash used since the IPO is described elsewhere in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of our periodic reports filed with the SEC. As of the date of this filing, there has been no material change in the planned use of proceeds from the IPO as described in the final prospectus for our IPO.

Item 3. Defaults Upon Senior Securities.

None.

Item 4. Mine Safety Disclosures.

Not applicable.

Item 5. Other Information.

Not applicable.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

2.    Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the instructions to Form 10-Q and Article 8 of Regulation S-X of the United States Securities and Exchange Commission (the “SEC”). In the Company’s opinion, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly the financial position, results of operations, and cash flows as of and for the periods presented. The condensed consolidated balance sheet at December 31, 2023 has been derived from audited consolidated financial statements as of that date. The unaudited condensed consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year or any other future year or period. Certain information and notes disclosure normally included in financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to instructions, rules, and regulations prescribed by the SEC. The Company believes that the disclosures provided herein are adequate to make the information presented not misleading when these unaudited interim condensed consolidated financial statements are read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K filed with the SEC on March 12, 2024.

Significant Accounting Policies

The Company’s significant accounting policies are disclosed in the notes to its audited consolidated financial statements for the year ended December 31, 2023 included in its Annual Report on Form 10-K and have not materially changed during the three months ended March 31, 2024.

Basis of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, CCTI, Inc. 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.

Concentration of Risk

The Company maintains its cash and cash equivalents with three financial institutions that management believes to be of high credit quality. At times, the Company’s cash 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 beyond the normal credit risk associated with commercial banking relationships.

Significant customers are those that accounted for 10% or more of the Company’s total revenue for the period or accounts receivable as of the end of a reporting period. During the three months ended March 31, 2024, two customers represented 23% and 18% of revenue, respectively. During the three months ended March 31, 2023, two customers represented 23% and 11% of revenue, respectively. As of March 31, 2024, two customers accounted for 23% 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 three months ended March 31, 2024, 30% of the Company’s additions to inventory was from one supplier. During the three months ended March 31, 2023, the Company purchased 60% of its inventory from one supplier. As of March 31, 2024, amounts payable to one supplier totaled 29% of total accounts payable.  At December 31, 2023, no supplier accounted for 10% or more of the Company’s total accounts payable.  

Accounts Receivable

Accounts receivable are reduced by an allowance for credit losses, if needed. The Company maintains an allowance for credit losses of an amount equal to anticipated future write-offs. The Company determined that no allowance was necessary at March 31, 2024.  The Company recorded an allowance for expected credit losses of $130 at December 31, 2023.

Foreign Currency

The Company’s functional currency is the US dollar; transactions denominated in foreign currencies are subject to currency risk. The Company recognized $33 in foreign currency transaction losses and $6 in foreign currency transaction gains for the three months ended March 31, 2024 and 2023, respectively.  

Leases

For transactions in which the Company is the lessee, at the inception of a contract, the Company determines if the arrangement is, or contains, a lease. See Note 7 for additional details about leases under which 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 on revenue recognition related to lease agreements.

Comprehensive Loss

For the three months ended March 31, 2024 and 2023, comprehensive loss equaled net loss; therefore, a separate statement of comprehensive loss is not included in the accompanying condensed 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.

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, restricted stock units, performance stock units and shares under employee stock purchase plans 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 excluded from the computation of diluted loss per share, consisting of shares underlying stock options, restricted stock units, performance stock units, and shares under employee stock purchase plans was 17.9 million for the three months ended March 31, 2024 and 17.1 million for the three months ended March 31, 2023.

Recent Accounting Pronouncements

The Company has evaluated all issued and unadopted Accounting Standards Updates and believes the adoption of these standards will not have a material impact on its results of operations, financial position, or cash flows.

Revenue

Revenue

3.    Revenue

Revenue is principally from the sale of instruments and processing assemblies, extended warranties and the lease of instruments, which lease agreements also include customer-specific milestone payments. In some arrangements, products 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 and processing assemblies is generally recognized at the time of shipment to the customer, provided that no significant vendor obligations remain and collectability is reasonably assured. Revenue from equipment leases is recognized ratably over the contractual term of the lease agreement and when specific milestones are achieved by a customer. Licensing fee revenue is recognized ratably over the license period. Revenue from fees for research services is recognized when services have been provided.

Disaggregation of Revenue

Additional Disclosures Relating to Revenue from Contracts with Customers

Deferred revenue represents payments received for performance obligations not yet satisfied and is presented as current or long-term in the accompanying condensed consolidated balance sheets based on the expected timing and satisfaction of the underlying goods or services. Deferred revenue was $4,755 and $5,352 as of March 31, 2024 and December 31, 2023, respectively. During the three months ended March 31, 2024 and March 31, 2023, the Company recognized $2,254 and $2,623 of revenue, respectively, that was included in deferred revenue at the beginning of such periods.

Remaining contract consideration for which revenue has not been recognized due to unsatisfied performance obligations with a duration greater than one year at March 31, 2024 was $360, of which the Company expects to recognize $81 in one year or less, $81 in one to two years, $41 in two to three years, and $157 thereafter.

For the three months ended March 31, 2024 and 2023, the Company did not incur, and therefore did not defer, any material incremental costs to obtain contracts or costs to fulfill contracts.

Stock Incentive Plans

The Company adopted the MaxCyte, Inc. Long-Term Incentive Plan (the “2016 Plan”) in January 2016 to provide for the awarding of (i) stock options, (ii) restricted stock, (iii) incentive shares, and (iv) performance awards, in each case, to employees, officers, and directors of the Company and to other individuals as determined by the Board of Directors.

In December 2021, the Company adopted the MaxCyte, Inc. 2021 Inducement Plan (the “Inducement Plan”) to provide for the awarding of (i) non-qualified stock options; (ii) stock appreciation rights; (iii) restricted stock awards; (iv) restricted stock unit awards; (v) performance awards; and (vi) other awards, in each case, only to persons eligible to receive grants of awards who satisfy the standards for inducement grants under Nasdaq Marketplace Rule 5635(c)(4) or 5635(c)(3), if applicable, and the related guidance under Nasdaq IM 5635-1. The Board of Directors reserved 2,500,000 shares for issuance under the Inducement Plan.

In May 2022, the Company’s Board of Directors adopted, and in June 2022, the Company’s stockholders approved, the MaxCyte, Inc. 2022 Equity Incentive Plan (the “2022 Plan”) to provide for the awarding of (i) incentive stock options, (ii) non-qualified stock options, (iii) stock appreciation rights, (iv) restricted stock awards, (v) restricted stock unit awards, (vi) performance awards, and (vii) other awards. Following the approval of the 2022 Plan, no additional awards can be

granted under the 2016 Plan or the Inducement Plan, but all outstanding awards will continue to remain subject to the terms of the applicable plan.

Upon the effectiveness of the 2022 Plan, a total of 3,692,397 shares were initially reserved for issuance pursuant to future awards under the 2022 Plan, consisting of 1,928,000 new shares and 1,764,397 shares previously available under the 2016 Plan. If and to the extent that outstanding options under the 2016 Plan or the Inducement Plan are forfeited, the shares underlying such forfeited options will become available for issuance under the 2022 Plan. At the Company’s Annual Meeting of Stockholders held on June 22, 2023, the Company’s stockholders voted to reserve an additional 6,069,000 shares of issuance pursuant to future awards under the 2022 Plan.

At March 31, 2024 and December 31, 2023, there were 4,353,000 and 6,202,000 shares, respectively, available to be issued under the 2022 Plan.

The value of an equity award is recognized as expense on a straight-line basis over the requisite service period. At March 31, 2024, total unrecognized compensation expense was $25,434, which will be recognized over an estimated weighted average period of 2.6 years.

Stock Options

The weighted-average fair value of the stock options granted during the three months ended March 31, 2024 and 2023 was estimated to be $2.23 and $2.04, per option share, respectively.  

Restricted Stock Units (“RSUs”)

The weighted-average fair value of the RSUs granted during the three months ended March 31, 2024 and 2023 was estimated to be $4.36 and $4.35 per RSU, respectively.

Performance Stock Units (“PSUs”)

During the three months ended March 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 three months ended March 31, 2024 was estimated to be $4.31 per PSU. During the three months ended March 31, 2024, the Company determined that it was probable that the grants will vest at 100% of the target number of PSUs.  Stock-based compensation expense for the service period since the grant date of $197 was recognized in the three months ended March 31, 2024.  The Company did not issue PSUs prior to January 2024.

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Company had no financial assets or liabilities measured at fair value on a recurring basis as of March 31, 2024 or December 31, 2023.

Financial Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

Money market funds, US Treasury securities and government agency bonds, commercial paper and corporate debt instruments classified as held-to-maturity are measured at fair value on a non-recurring basis when they are deemed to be impaired on an other-than-temporary basis.

Summary of Significant Accounting Policies (Policies)

Summary of Significant Accounting Policies

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the instructions to Form 10-Q and Article 8 of Regulation S-X of the United States Securities and Exchange Commission (the “SEC”). In the Company’s opinion, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly the financial position, results of operations, and cash flows as of and for the periods presented. The condensed consolidated balance sheet at December 31, 2023 has been derived from audited consolidated financial statements as of that date. The unaudited condensed consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year or any other future year or period. Certain information and notes disclosure normally included in financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to instructions, rules, and regulations prescribed by the SEC. The Company believes that the disclosures provided herein are adequate to make the information presented not misleading when these unaudited interim condensed consolidated financial statements are read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K filed with the SEC on March 12, 2024.

Principles of Consolidation

Basis of Consolidation

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

Reclassifications

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.

Concentrations of Risk

Concentration of Risk

The Company maintains its cash and cash equivalents with three financial institutions that management believes to be of high credit quality. At times, the Company’s cash 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 beyond the normal credit risk associated with commercial banking relationships.

Significant customers are those that accounted for 10% or more of the Company’s total revenue for the period or accounts receivable as of the end of a reporting period. During the three months ended March 31, 2024, two customers represented 23% and 18% of revenue, respectively. During the three months ended March 31, 2023, two customers represented 23% and 11% of revenue, respectively. As of March 31, 2024, two customers accounted for 23% 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 three months ended March 31, 2024, 30% of the Company’s additions to inventory was from one supplier. During the three months ended March 31, 2023, the Company purchased 60% of its inventory from one supplier. As of March 31, 2024, amounts payable to one supplier totaled 29% of total accounts payable.  At December 31, 2023, no supplier accounted for 10% or more of the Company’s total accounts payable.  

Foreign Currency

Foreign Currency

The Company’s functional currency is the US dollar; transactions denominated in foreign currencies are subject to currency risk. The Company recognized $33 in foreign currency transaction losses and $6 in foreign currency transaction gains for the three months ended March 31, 2024 and 2023, respectively.  

Accounts Receivable

Accounts Receivable

Accounts receivable are reduced by an allowance for credit losses, if needed. The Company maintains an allowance for credit losses of an amount equal to anticipated future write-offs. The Company determined that no allowance was necessary at March 31, 2024.  The Company recorded an allowance for expected credit losses of $130 at December 31, 2023.

Leases

Leases

For transactions in which the Company is the lessee, at the inception of a contract, the Company determines if the arrangement is, or contains, a lease. See Note 7 for additional details about leases under which 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 on revenue recognition related to lease agreements.

Comprehensive Loss

Comprehensive Loss

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

Loss Per Share

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.

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, restricted stock units, performance stock units and shares under employee stock purchase plans 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 excluded from the computation of diluted loss per share, consisting of shares underlying stock options, restricted stock units, performance stock units, and shares under employee stock purchase plans was 17.9 million for the three months ended March 31, 2024 and 17.1 million for the three months ended March 31, 2023.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

The Company has evaluated all issued and unadopted Accounting Standards Updates and believes the adoption of these standards will not have a material impact on its results of operations, financial position, or cash flows.
