Notes to Unaudited Condensed Financial Statements

1.NATURE OF BUSINESS AND BASIS OF PRESENTATION

Business

iSpecimen Inc. (“iSpecimen” or the “Company”) was incorporated in 2009 under the laws of the state of Delaware. The Company has developed and launched a proprietary online marketplace platform that connects medical researchers who need access to subjects, samples, and data, with hospitals, laboratories, and other organizations who have access to them. iSpecimen is a technology-driven company founded to address a critical challenge: how to connect life science researchers who need human biofluids, tissues, and living cells (“biospecimens”) for their research, with biospecimens available (but not easily accessible) in healthcare provider organizations worldwide. The Company’s proprietary platform, the iSpecimen Marketplace platform, was designed to solve this problem and transform the biospecimen procurement process to accelerate medical discovery. The Company is headquartered in Lexington, Massachusetts and its principal market is North America. The Company operates as one operating and reporting segment.

Basis of Presentation

The accompanying unaudited condensed financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) as determined by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) for interim financial information, and, pursuant to the rules and regulations of Article 10 of Regulation S-X of the Securities Act of 1933, as amended (the “Securities Act”), published by the Securities and Exchange Commission (“SEC”) for interim financial statements. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the unaudited condensed financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results of operations for the periods presented. They may not include all of the information and footnotes required by GAAP for complete financial statements. Therefore, these unaudited condensed financial statements should be read in conjunction with the Company’s audited financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

Going Concern Uncertainty and Management’s Plan

The Company has recognized recurring losses since inception. As of March 31, 2024, the Company had negative working capital of $414,722, an accumulated deficit of $62,266,929, cash and cash equivalents and short-term investments of $2,556,384, and accounts payable and accrued expenses of $5,271,289. Since inception, the Company has relied upon raising capital and its revenues to finance operations.

The future success of the Company is dependent on its ability to successfully obtain additional working capital and/or to ultimately attain profitable operations. The Company has initiated efforts to decrease its capital and operational expenditures by cutting costs and right sizing the Company through reductions in workforce. During the year ended December 31, 2023 and the first quarter of 2024, the Company executed reductions in workforce, resulting in an estimated reduction in monthly compensation costs of approximately 41% and technology costs of approximately 66% in the three months ended March 31, 2024, after streamlining operations and rationalizing resources to focus on key market opportunities. In addition, the Company plans to add additional customers and suppliers to increase and add additional revenues through its new revenue enhancement projects as well as to reduce and manage expenditures to improve its financial position and ensure continued funding of operations. However, as certain elements of the Company’s operating plan are not within the Company’s control, the Company is unable to assess their probability of success. The Company may also seek to fund its operations through public equity or debt financing, as well as other sources.

On March 5, 2024, the Company put in place an At the Market Offering Agreement (the “ATM Agreement”) which may allow the Company to issue and sell shares of its common stock, having an aggregate offering price of up to $1,500,000 (the “ATM Shares”), from time to time through the Sales Agent (as defined below under Note 9). During the three months ended March 31, 2024, the Company sold 337,970 shares of common stock for gross proceeds of approximately $138,000 under the ATM Agreement. The Company incurred offering costs of approximately $205,000 resulting in a net cost of approximately $67,000.

iSpecimen Inc.

Notes to Unaudited Condensed Financial Statements

The Company may be unsuccessful in increasing its revenues from its new enhancement projects or contain its operating expenses, or it may be unable to raise additional capital on commercially favorable terms. The Company’s failure to generate additional revenues or contain operating costs would have a negative impact on the Company’s business, results of operations and financial condition and the Company’s ability to continue as a going concern. If the Company does not generate enough revenue to provide an adequate level of working capital, its business plan will be scaled down further.

These conditions raise substantial doubt regarding the Company’s ability to continue as a going concern for a period of one year from the date these unaudited condensed financial statements are issued. Management’s plan to mitigate the conditions that raise substantial doubt includes generating additional revenues through its revenue enhancement projects, deferring certain projects and capital expenditures and eliminating certain future operating expenses for the Company to continue as a going concern. However, there can be no assurance that the Company will be successful in completing any of these options. As a result, management’s plans cannot be considered probable and thus do not alleviate substantial doubt about the Company’s ability to continue as a going concern.

The accompanying unaudited condensed financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The unaudited condensed financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described above.

Impact of the Current Economy

The Company’s financial performance is subject to global economic conditions and their impact on the levels of spending by its customer research organizations, particularly discretionary spending for procurement of specimens used for research. Economic recessions may have adverse consequences across industries, including the health and biospecimen industries, which may adversely affect the Company’s business and financial condition. The Company increased its allowance for doubtful accounts in accounts receivables by $197,924 during the three months ended March 31, 2024 due to certain boutique life sciences customers either lacking liquidity or having filed for bankruptcy. The Company has enhanced procedures related to its credit check process for new and existing customers to mitigate the risk to future collectability of receivables.

Changes in general market, economic and political conditions in domestic and foreign economies or financial markets, including fluctuation in stock markets resulting from, among other things, trends in the economy and inflation, as are being currently experienced, may result in a reduction in researchers’ demand for specimens due to the research organization’s inability to obtain funding.

To further address the current market conditions, the Company has taken steps, that include, but are not limited to, reevaluating its pricing in order to be more competitive, creating campaigns to highlight and fast-track high demand items, enhancing internal team communications to accelerate the sales cycle, moving to a new line of business structure organized by its internal categorization of biospecimen suppliers’ capabilities to increase efficiency in operations, implementation of next day quotes to increase conversion ratios of quotes to purchase orders, and initiation of efforts to decrease expenditures through reductions in workforce.  

The Company believes that its business will continue to be resilient through a continued industry-wide economic slowdown in life science research, and that the Company has and will continue to work on improving liquidity to address its financial obligations and alleviate possible adverse effects on its business, financial condition, results of operations or prospects.

Impact of the Russian-Ukrainian War on the Company’s Operations

The Company’s business was negatively impacted during the first half of 2022 by the ongoing war between Russia and Ukraine. At the start of the war, the Company had approximately $1 million of purchase orders that were slated to be fulfilled by the Company’s supply network in Ukraine and Russia. This supply network was shut down at the start of the war. Ukrainian suppliers were disabled due to war conditions and evacuations and some of the Company’s Russian suppliers were disabled by sanctions. While the Company mobilized to shift these purchase orders to other suppliers in the network, the process of specimen collections from other supply sites took time, which caused a delay in the fulfillment of such purchase orders. Alternate suppliers do not have the same favorable unit

Notes to Unaudited Condensed Financial Statements

economics or specimen collection rates, and this also impacted the Company’s margins. Additionally, key resources were diverted from operations to resolving the re-fulfillment issues caused by the conflict.

As of March 31, 2024, the Company’s supply sites in Russia that had not been under sanctions were accessible and the Company’s supply sites in Ukraine were mostly reopened. However, logistics and transportation of specimens out of the country of Ukraine remains challenging and not as economically feasible as they were prior to the beginning of the war. Due to the uncertainty caused by the ongoing war, Ukrainian and Russian suppliers may again become inaccessible to the Company. Therefore, as long as the uncertainty continues, the Company’s policy is to ensure at a purchase order level that an order is not solely sourced from the two countries. The short and long-term implications of the war are difficult to predict as of the filing date of the Company’s Quarterly Report on Form 10-Q in which these unaudited condensed financial statements are included (the “Quarterly Report”). The imposition of more sanctions and countersanctions may have an adverse effect on the economic markets generally and could impact the Company’s business and the businesses of the Company’s supply partners, especially those in Ukraine and Russia. Because of the highly uncertain and dynamic nature of these events, it is not currently possible to estimate the impact of the war on the Company’s business and the companies from which the Company obtains supplies and distributes specimens.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company’s significant accounting policies and recent accounting standards are summarized in Note 2 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. There were no significant changes to these accounting policies during the three months ended March 31, 2024.

Use of Estimates

The preparation of the Company’s unaudited condensed financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Company utilizes certain estimates in the determination of the deferred tax valuation allowances, revenue recognition, stock-based compensation, allowance for doubtful accounts, accrued expenses, and the useful lives of internally developed software and sequenced data. The Company bases its estimates on historical experience and other market-specific or other relevant assumptions that it believes to be reasonable under the circumstances. Actual results could differ from such estimates.

Investments

The Company’s investments are considered to be available-for-sale as defined under ASC 320, Investments – Debt Securities, and are recorded at fair value. Unrealized gains and losses are included in accumulated other comprehensive income. Purchases and sales of securities are reflected on a trade-date basis. Realized gains or losses are released from accumulated other comprehensive income and into earnings on the statement of operations, and amortization of premiums and accretion of discounts on the U.S treasury bills are recorded in interest expense or income, respectively.

The Company continually monitors the difference between its cost basis and the estimated fair value of its investments. The Company’s accounting policy for impairment recognition requires other-than-temporary impairment charges to be recorded when it determines that it is more likely than not that it will be unable to collect all amounts due according to the contractual terms of the fixed maturity security or that the anticipated recovery in fair value of the equity security will not occur in a reasonable amount of time. Impairment charges on investments are recorded based on the fair value of the investments at the measurement date or based on the value calculated using a discounted cash flow model. Credit-related impairments on fixed maturity securities that the Company does not plan to sell, and for which it is not more likely than not to be required to sell, are recognized in net income. Any non-credit related impairment is recognized as a component of other comprehensive income. Factors considered in evaluating whether there is a decline in value include: the length of time and the extent to which the fair value has been less than cost; the financial condition and near-term prospects of the issuer; and the likelihood that it will be required to sell the investment.

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability of fair value measures, the following hierarchy prioritizes the inputs to valuation methodologies used to measure fair value:

● Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets.

● Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

● Level 3 — Valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.

For certain financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable, the carrying amounts approximate their fair values as of March 31, 2024 and December 31, 2023, respectively, because of their short-term nature. Available-for-sale securities are recorded at fair value and as level 1 investments.

Revenue Recognition and Accounts Receivable

The Company recognizes revenue using the five-step approach as follows: (1) identify the contract with the customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when (or as) the Company satisfies the performance obligations.

The Company generates revenue by procuring various specimens from hospitals, laboratories, and other supply sites, for the Company’s medical research customers using the Company’s proprietary software, the iSpecimen Marketplace, to identify, locate, and ultimately validate the required specimens to the Company’s customers’ requested specifications. The Company’s performance obligation is to procure a specimen meeting the customer’s specification(s) from a supplier, on a “best efforts” basis, for the Company’s customer at the agreed price per specimen as indicated in the customer’s contract with the Company. The Company does not currently charge suppliers or customers for the use of the Company’s proprietary software. Each customer will execute a material and data use agreement with the Company or agree to online purchase terms, each of which includes terms such as specimen and data use, shipment terms, payment, and cancellation terms. These are then supplemented by purchase orders that specify specimen requirements including detailed inclusion/exclusion criteria, quantities to be collected, and pricing. Collectively, these customer agreements represent the Company’s contracts with its customer. Generally, contracts have fixed unit pricing. For certain specimen orders, a refundable customer deposit may be required prior to order fulfillment depending on project set-up requirements, which is presented as deferred revenue. The Company expects to recognize the deferred revenue within the next twelve months.

Specimen collections occur at supply sites within the Company’s network. “Collection” is when the specimen has been removed, or “collected” from the patient or donor. A specimen is often collected specifically for a particular Company order. Once collected, the specimen is assigned by the supplier to the Company and control of the specimen passes to the Company. “Accession” is the process whereby a collected specimen and associated data are registered and assigned in the iSpecimen Marketplace to a particular customer order, which can occur while a specimen is at the supplier site or while at the Company site and it is when control of the specimen passes to the customer. Suppliers may ship specimens to the Company or directly to the customer if specimens must be delivered within a short time period (less than 24 hours after collection) or shipping to the Company is not practical.

The Company has evaluated principal versus agent considerations as part of the Company’s revenue recognition policy. The Company has concluded that it acts as principal in the arrangement as it manages the procurement process from beginning to end and determines which suppliers will be used to fulfill an order, usually takes physical possession of the specimens, sets prices for the specimens, and bears the responsibility for customer credit risk.

Notes to Unaudited Condensed Financial Statements

The Company recognizes revenue over time, as the Company has created an asset with no alternative use to the Company, which has an enforceable right to payment for performance completed to date. At contract inception, the Company reviews a contract and related order upon receipt to determine if the specimen ordered has an alternative use by the Company. Generally, specimens ordered do not have an alternative future use to the Company and the performance obligation is satisfied when the related specimens are accessioned. The Company uses an output method to recognize revenue for specimens with no alternative future use. The output is measured based on the number of specimens accessioned. In the rare circumstances where specimens do have an alternative future use, the Company's performance obligation is satisfied at the time of shipment.

Customers are generally invoiced upon shipment. Depending on the quantity of specimens ordered, it may take several accounting periods to completely fulfill a purchase order. In other words, there can be multiple invoices issued for a single purchase order, reflecting the specimens being accessioned over time. However, specimens are generally shipped as soon as possible after they have been accessioned.

Once a specimen that has no alternative future use and for which the Company has an enforceable right to payment has been accessioned, the Company records the offset to revenue in accounts receivable – unbilled. Once the specimen has been shipped and invoiced, a reclassification is made from accounts receivable - unbilled to accounts receivable.

Customers are generally given fourteen days from the receipt of specimens to inspect the specimens to ensure compliance with specifications set forth in the purchase order documentation. Customers are entitled to either receive replacement specimens or receive reimbursement of payments made for such specimens. The Company has a nominal history of returns for nonacceptance of specimens delivered. When this occurs, the Company gives the customer a credit for the returns. The Company has not recorded a returns allowance.

The following table summarizes the Company’s revenue for the three months ended March 31:

	2024		2023
Specimens - contracts with customers	$	2,136,100	$	2,712,376
Shipping and other		153,893		237,821
Revenue	$	2,289,993	$	2,950,197

The Company carries its accounts receivable at the invoiced amount less an allowance for doubtful accounts. On a periodic basis, the Company evaluates its accounts receivable to determine if an allowance for doubtful accounts is necessary, based on economic conditions and each customer’s payment history. Receivables are written off when deemed uncollectible, with any future recoveries recorded as income when received. As of March 31, 2024 and December 31, 2023, the Company had an allowance for doubtful accounts of $718,821 and $520,897, respectively.

The Company applies the practical expedient to account for shipping and handling activities as fulfillment cost rather than as a separate performance obligation. Shipping and handling costs incurred are included in cost of revenue.

Internally Developed Software, Net

The Company capitalizes certain internal and external costs incurred during the application development stage of internal-use software projects until the software is ready for its intended use. Amortization of the asset commences when the software is complete and placed into service and is recorded in operating expenses. The Company amortizes completed internal-use software over its estimated useful life of five years on a straight-line basis. Costs incurred during the planning, training and post-implementation stages of the software development life cycle are classified as technology costs and are expensed to operations as incurred.

Other Intangible Assets, Net

The Company procures data generated from sequencing of Formalin-Fixed Paraffin-Embedded (“FFPE”) blocks from a third-party sequencer which the Company licenses to its customers with the sale of FFPE blocks at an additional cost. The sequenced data is also organized to form a database of research content that is available for sale through a subscription model. The Company has determined that the sequenced data is an intangible asset and capitalizes the cost to procure the sequenced data. The sequenced data is amortized to

12

iSpecimen Inc.

Notes to Unaudited Condensed Financial Statements

cost of revenue over an estimated useful life of five years on a straight-line basis. The costs paid to the third-party sequencer are the only costs capitalized and all other related costs are expensed to operations as incurred.

Impairment of Long-Lived Assets

Management reviews long-lived assets for impairment when circumstances indicate the carrying amount of an asset may not be recoverable. An impairment loss is recognized when expected cash flows are less than the asset’s carrying value. Long-lived assets consist of property and equipment, internal-use software and other intangible assets. No impairment charges were recorded for the three months ended March 31, 2024 and 2023.

Stock-Based Compensation

The Company records stock-based compensation for options granted to employees, non-employees, and to members of the board of directors for their services to the Company based on the grant date fair value of awards issued, and the expense is recorded on a straight-line basis over the requisite service period. Forfeitures are recognized when they occur.

The Company uses the Black-Scholes-Merton option pricing model to determine the fair value of stock options. The use of the Black-Scholes-Merton option pricing model requires management to make assumptions with respect to the expected term of the option, the expected volatility of the common stock consistent with the expected life of the option, risk-free interest rates and expected dividend yields of the common stock. The Company has concluded that its historical share option exercise experience does not provide a reasonable basis upon which to estimate expected term. Therefore, the expected term was determined according to the simplified method, which is the average of the vesting tranche dates and the contractual term. Due to the lack of Company-specific historical and implied volatility data, the estimate of expected volatility is primarily based on the historical volatility of a group of similar companies that are publicly traded. For these analyses, companies with comparable characteristics are selected, including enterprise value and position within the industry, and with historical share price information sufficient to meet the expected life of the stock-based awards. The Company computes the historical volatility data using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term of its stock-based awards.

The risk-free interest rate is determined by reference to U.S. Treasury zero-coupon issues with remaining maturities similar to the expected term of the options. The Company has not paid, and does not anticipate paying, cash dividends on shares of its common stock.

The fair value of the Company’s common stock is equal to the closing price on the specified grant date.

Restricted Stock Units (“RSUs”)

The Company recognizes stock-based compensation expense from RSUs ratably over the specified vesting period. The fair value of RSUs is determined to be the closing share price of the Company’s common stock on the grant date.

Common Stock Warrants

The Company accounts for common stock warrants as either equity instruments or liabilities, depending on the specific terms of the warrant agreement. The warrants shall be classified as a liability if 1) the underlying shares are classified as liabilities or 2) the entity can be required under any circumstances to settle the warrant by transferring cash or other assets. The measurement of equity-classified non-employee stock-based payments is generally fixed on the grant date and are considered compensatory. For additional discussion on warrants, see Note 9.

Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss applicable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by adjusting the weighted-average number of shares outstanding for the dilutive effect of common stock equivalents

outstanding for the period, determined using the treasury-stock method. Therefore, basic and diluted net loss per share applicable to common stockholders were the same for all periods presented.

The table below provides information on shares of the Company’s common stock issuable upon vesting and exercise, as of March 31:

	2024	2023
Shares issuable upon vesting of RSUs	96,788	216,058
Shares issuable upon exercise of stock options	350,062	330,788

Recently Adopted Accounting Standards

In June 2016, the FASB issued Accounting Standards Updates (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the impairment model for most financial assets and certain other instruments. For receivables, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowance for losses. In addition, an entity will have to disclose significantly more information about allowances and credit quality indicators. The new standard is effective for the Company for fiscal years beginning after December 15, 2022. The Company adopted this new standard as of January 1, 2023. ASU 2016-13 did not have a material impact on the Company’s unaudited condensed financial statements.

In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies an issuer’s accounting for convertible instruments by reducing the number of accounting models that require separate accounting for embedded conversion features. ASU 2020-06 also simplifies the settlement assessment that entities are required to perform to determine whether a contract qualifies for equity classification and makes targeted improvements to the disclosures for convertible instruments and earnings-per-share (EPS) guidance. This update will be effective for the Company’s fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Entities can elect to adopt the new guidance through either a modified retrospective method of transition or a fully retrospective method of transition. The Company adopted this new standard as of January 1, 2024. ASU 2020-06 did not have a material impact on the Company’s unaudited condensed financial statements.

3.AVAILABLE-FOR-SALE SECURITIES

The Company purchased U.S. Treasury bills during the three months ended March 31, 2024 and has classified them as available-for-sale securities. The amortized cost, gross unrealized gains and losses, and fair value for available-for-sale securities as of March 31, 2024 and December 31, 2023 are as follows:

	March 31, 2024

Total Available-for-sale securities	$	2,661,092	$	36,138	$	(35,298)	$	2,661,932

The Company recorded $680 of realized losses in the three months ended March 31, 2024. The Company did not have any realized gains or losses in the three months ended March 31, 2023. Maturities of the U.S. Treasury bills are all due within the current fiscal year. Marketable securities in an unrealized loss position as of March 31, 2024 were not deemed impaired at acquisition and subsequent declines in fair value are not deemed attributed to declines in credit quality. The Company believes that it is more likely than not that it will receive a full recovery of par value on the securities, although there can be no assurance that such recovery will occur.

4.PROPERTY AND EQUIPMENT, NET

Property and equipment, net consisted of the following at the dates indicated:

	March 31,		December 31,

Accumulated depreciation		(460,781)		(444,731)
Total property and equipment, net	$	120,873	$	127,787

Depreciation expense for property and equipment was $16,050 and $38,589 for the three months ended March 31, 2024 and 2023, respectively.

5.INTERNALLY DEVELOPED SOFTWARE, NET

During the three months ended March 31, 2024 and 2023, the Company capitalized $275,486 and $1,539,546, respectively, of internally developed software costs in connection with the development and continued enhancement of the technology platform and web interfaces. Capitalized costs primarily consist of payroll and payroll-related costs for the Company’s employees. The Company recognized $532,750 and $433,326 of amortization expense associated with capitalized internally developed software costs during the three months ended March 31, 2024 and 2023, respectively. Accumulated amortization associated with capitalized internally developed software costs as of March 31, 2024 and December 31, 2023 was $7,497,505 and $6,964,755, respectively.

6. OTHER INTANGIBLE ASSETS, NET

During the three months ended March 31, 2024, the Company did not sequence any FFPE blocks and therefore did not capitalize any sequenced data as other intangible assets. The Company licenses to its customers, at an additional cost, the sequenced data associated with the sequenced FFPE blocks with the sale of said FFPE blocks. The sequenced data is also organized to form a database of research content that is available for sale to the Company’s customers through a subscription model. The Company recognized $47,889 of amortization expense associated with the capitalized sequenced data during the three months ended March 31, 2024. No amortization

8.COMMITMENTS AND CONTINGENCIES

Leases

The Company has one operating lease of office space in Lexington, Massachusetts, which was initially set to expire on February 28, 2024. The lease was renewed on September 27, 2023 to extend the lease term for a period of 12 months from February 29, 2024 through February 28, 2025. The lease renewal includes an option to terminate the lease before its expiration date if notice is provided to the lessor by June 30, 2024.

Leases with an initial term of twelve months or less are not recorded on the balance sheet date, and the Company does not separate lease and non-lease components of contracts. There are no material residual guarantees associated with any of the Company’s leases, and there are no significant restrictions or covenants included in the Company’s lease agreements.

The Company’s lease agreement does not provide an implicit borrowing rate. Therefore, the Company used a benchmark approach to derive an appropriate imputed discount rate. The Company benchmarked itself against other companies of similar credit ratings and comparable quality and derived an imputed rate, which was used to discount its real estate lease liabilities.

There was no sublease rental income for the three months ended March 31, 2024, and the Company is not the lessor in any lease arrangement, and there were no related-party lease agreements.

Non-cash operating lease expense (operating cash flow)	$	40,517
Change in operating lease liabilities (operating cash flow)	$	(39,541)

Sales Tax Payable

The majority of the Company’s customers are researchers, universities, hospitals, and not-for-profit entities that were believed by the Company to have a sales and use tax exemption that generally excludes them from paying sales taxes. The main types of specimens the Company sells are blood, blood plasma, human tissue, human parts, and human bodily fluids and only a few of these products are typically not taxable in some states regardless of the buyer’s tax exemption status. The Company historically has not collected sales tax in states where it had sales. Had the Company contemporaneously collected and remitted sales tax for all customers and in all jurisdictions where it would have been required, there would have been no material impact on the Company’s unaudited condensed financial statements.

As a result of an entity-wide risk assessment process that commenced in the second quarter of 2023, the Company engaged external tax consultant advisors to complement internal resources and efforts to provide support in assessing the appropriate sales tax treatment associated with the Company’s products for all prior years in which the Company had generated revenue, to assist with the facilitation and tracking of Voluntary Disclosure Agreements (“VDAs”) in jurisdictions where a potential tax liability may exist and to assist with the implementation of a sales tax software platform solution for the calculation, communication, collection, and remittance of sales tax for all non-exempt future sales.

From the Company’s inception through the filing date of this Quarterly Report, the Company now believes that an obligation to collect and remit sales tax existed for certain of its sales of products to certain of its customers. The Company has analyzed its product sales, on an invoice-by-invoice and customer-by-customer basis, to determine which products are subject to sales tax in each jurisdiction, and determining which of its customers are exempt from sales tax, and which customers who were not exempt from sales tax have already paid compensating use tax to the appropriate jurisdiction. Part of this process includes requesting and obtaining exemption letters or representations from its customers or proof of payment of their compensating use tax. As the Company continues to make progress on this project, certain customers have notified the Company that they are not exempt from the payment of sales tax and have not remitted use tax and the Company has started to invoice such customers for past sales tax due.  

As of March 31, 2024, the Company had accrued a sales tax liability of approximately $710,000 and the related interests and penalties of approximately $208,000 in accrued expenses on the balance sheet. The estimated liability represents the estimated tax liability for sales made to customers who have notified the Company that they are not exempt from sales taxes and customers who have not responded to the Company’s request to provide a sales exemption letter. As of March 31, 2024, the Company had recovered approximately $412,000 of prior taxes from certain customers who do not have a sales tax exemption. The Company continues to pursue those non-responsive customers and expects over time that further exemption letters or representations will be received that will reduce the liability. The Company did not recognize any additional loss in its statement of operations and comprehensive loss related to the sales tax liability during the three months ended March 31, 2024. The Company is in the process of commencing its VDA filings with relevant taxing jurisdictions regarding its noncompliance, during which it will remit its sales tax obligations.

Legal Proceedings

From time to time the Company is involved in litigation, claims, and other proceedings arising in the ordinary course of business. Such litigation and other proceedings may include, but are not limited to, actions relating to employment law and misclassification, intellectual property, commercial or contractual claims, or other consumer protection statutes. Litigation and other disputes are inherently

unpredictable and subject to substantial uncertainties and unfavorable resolutions could occur. As of March 31, 2024, there was no material litigation against the Company.

9.STOCKHOLDERS’ EQUITY

The Company’s authorized capital is 250,000,000 shares, of which (1) 200,000,000 shares are common stock, par value $0.0001 per share and (2) 50,000,000 shares are preferred stock, par value $0.0001 per share, which may, at the sole discretion of the Company’s board of directors, be issued in one or more series.

Common Stock

On March 5, 2024, the Company entered into the ATM Agreement with Rodman & Renshaw LLC as agent (the “Sales Agent”) pursuant to which the Company may issue and sell shares of its common stock, having an aggregate offering price of up to $1,500,000 (the “ATM Shares”), from time to time through the Sales Agent (the “ATM Offering”). The ATM Shares when issued will be registered pursuant to the Company’s “shelf” registration statement on Form S-3 (File No 333-265976), which became effective on July 12, 2022. The Company intends to sell the ATM Shares, from time to time, pursuant to the ATM Agreement, in transactions that are “at the market offerings” as defined in Rule 415(a)(4) promulgated under the Securities Act. During the three months ended March 31, 2024, the Company issued 337,970 shares of common stock for gross proceeds of approximately $138,000, under the ATM Agreement. The Company paid expenses of approximately $205,000 in connection with the ATM Offering, resulting in a net cost of approximately $67,000.

During the three months ended March 31, 2023, the Company issued 67,736 shares of common stock for cash exercises of options of $67,736. There were no options exercises during the three months ended March 31, 2024.

Warrants

Underwriter Warrants

In connection with the Company's underwriting agreement with ThinkEquity, a division of Fordham Financial Management, Inc. (“ThinkEquity”) and the representative of the Company’s IPO underwriters, the Company entered into a warrant agreement to purchase up to 90,000 shares of common stock to several affiliates of ThinkEquity (the “Underwriter Warrants”). The Underwriter Warrants are exercisable at a per share exercise price of $10.00 and are exercisable at any time and from time to time, in whole or in part, during the four- and one-half year period commencing 180 days from the effective date of the IPO registration statement. The Underwriter Warrants became exercisable on or after December 16, 2021 (six months from the effective date of the offering) and expire on June 15, 2026. Upon issuance of the Underwriter Warrants, as partial compensation for its services as an underwriter, the fair value of approximately $0.4 million was recorded as equity issuance costs in the year ended December 31, 2021. As of March 31, 2024, the Underwriter Warrants had not been exercised, and had a weighted average exercise price of $10 per share and a remaining weighted average time to expiration of 2.21 years.

Lender Warrant

In connection with the loan agreement entered into with Western Alliance Bank (the “Lender”) on August 13, 2021, the Company issued a warrant (the “Lender Warrant”) to the Lender to purchase 12,500 shares of common stock of the Company. The Lender Warrant is exercisable at a per share exercise price of $8.00 and is exercisable at any time on or after August 13, 2021 through August 12, 2031. The Company determined that the Lender Warrant was equity-classified. As of March 31, 2024, the Lender Warrant had not been exercised, and had a weighted average exercise price of $8 per share and a remaining weighted average time to expiration of 7.37 years.

PIPE Warrants

On December 1, 2021, the Company completed a private placement (the “PIPE”) in which the Company issued warrants (the “PIPE Warrants”) to purchase up to an aggregate of 1,312,500 shares of common stock. These PIPE Warrants have an exercise price of $13.00 per share and are immediately exercisable upon issuance and will expire on the five and one-half-year anniversary of the issuance date.

On February 13, 2024, the Company entered into certain warrant repurchase and termination agreements with the holders of the PIPE Warrants to repurchase the PIPE Warrants for a purchase price equal to $0.04 multiplied by the number of shares of common stock issuable pursuant to such PIPE Warrants. In connection with such repurchases, all past, current and future obligations of the Company relating to the PIPE Warrants were released, discharged and are of no further force or effect.

A summary of total warrant activity during the three months ended March 31, 2024 is as follows:

Stock Incentive Plans

2021 Plan

In March 2021, the Company adopted the iSpecimen Inc. 2021 Stock Incentive Plan, which was subsequently amended in June 2021 and then on May 25, 2022 (the “2021 Plan”). The 2021 Plan was adopted to enhance the Company’s ability to attract, retain and motivate employees, officers, directors, consultants, and advisors by providing such persons with equity ownership opportunities and performance-based incentives. The 2021 Plan authorizes options, restricted stock, RSUs and other stock-based awards. The Company's board of directors, or any committee to which the board of directors delegates such authority, has the sole discretion in administering, interpreting, amending, or accelerating the 2021 Plan. Awards may be made under the 2021 Plan for up to 608,000 shares of the Company's common stock, and the 2021 Plan was made effective with the completion of the IPO.

On May 24, 2023, at the Company’s annual meeting of stockholders, the stockholders approved an amendment to the 2021 Plan to increase the number of shares under the 2021 Plan from 608,000 shares of common stock to 1,869,500 shares of common stock.

During the three months ended March 31, 2024 and 2023, 80,340 and 118,247 equity awards were granted under the 2021 Plan, respectively. As of March 31, 2024, there were 1,320,028 shares of common stock available for future grants under the 2021 Plan.

2013 Plan

The iSpecimen Inc. 2013 Stock Incentive Plan (the “2013 Plan”) was adopted on April 12, 2013 and subsequently amended on July 29, 2015. The aggregate number of shares of common stock that may be issued pursuant to the 2013 Plan was 1,713,570.

No equity awards were granted under the 2013 Plan during the three months ended March 31, 2024 and 2023. According to the 2013 Plan, which was adopted by the Company’s board of directors on April 12, 2013, no awards shall be granted under the 2013 Plan after

11.INCOME TAXES

As of March 31, 2024 and December 31, 2023, the Company had federal net operating loss carryforwards of approximately $53,200,000 and $50,800,000, respectively, of which approximately $13,000,000 expires at various periods through 2037 and approximately $40,200,000 and $37,800,000, respectively, can be carried forward indefinitely. As of March 31, 2024 and December 31, 2023, the Company had state net operating loss carryforwards of approximately $32,300,000 and $31,100,000, respectively, that expire at various periods through 2043, respectively. As of March 31, 2024 and December 31, 2023, the Company had federal and state tax credits of approximately $2,110,700 and $2,058,300, respectively, available for future periods that expire at various periods through 2043. The Company has recorded a full valuation allowance against net deferred income tax assets due to a history of losses generated since inception.

Due to changes in ownership provisions of the Internal Revenue Code of 1986 (the “IRC”), the availability of the Company's net operating loss carryforwards may be subject to annual limitations under Section 382 of the IRC against taxable income in the future period, which could substantially limit the eventual utilization of such carryforwards.

Overview

We were incorporated in 2009 under the laws of the state of Delaware. Our mission is to accelerate life science research and development via a single global marketplace platform, the iSpecimen Marketplace, which connects researchers to subjects, specimens, and associated data. We are headquartered in Lexington, Massachusetts. We operate as one operating and reporting segment.

In addition to creating a single global platform where both specimen providers and researchers can connect, the platform automates the process of searching for and selecting specimens for research. The platform taps into healthcare provider data to gain insights into the available samples in biobanks or laboratories, or to gain insights into the patient populations to support specimen collections directly from research subjects. The platform receives de-identified data from electronic medical records, laboratory information systems, and other healthcare data sources of available specimens and research subjects and harmonizes the data across all participating organizations.

Researchers can search this data using our intuitive, web-based user interface to obtain specimens more efficiently. They can instantly find the specific specimens they need for their studies, request quotes for these specimens or for custom collections directly from research subjects, place orders, and track and manage their specimens and associated data across projects.

Biospecimen providers also gain efficiencies using the iSpecimen Marketplace, not only because the platform provides instant access to a large researcher base, but because the technology orchestrates the bioprocurement workflow from specimen request to fulfillment. Specimen providers can access intuitive dashboards to view requests, create proposals, and track and manage their orders.

Finally, the platform helps with administrative and reporting functions for researchers, suppliers, and our internal personnel, including user and compliance management.

The iSpecimen Marketplace is composed of four major functional areas: search, workflow, data, and administrative reporting. We continue to invest in the evolution of these areas to improve engagement with the platform and liquidity across it. Our core business objective is to retain and grow both researcher and supplier usage of our platform to support biospecimen procurement, as well as to position our Company to explore other adjacent business opportunities that can benefit from the use of the iSpecimen Marketplace.

23

The iSpecimen Marketplace currently supports the supply chain management and bioprocurement process for specimens and associated data. We generate revenue by procuring various specimens from hospitals, laboratories, and other supply sites comprising our network, and delivering them to our medical research customers using our proprietary software to identify and locate the required specimens. Costs paid to acquire specimens from hospitals and laboratories generally vary depending upon the sample type, collection requirements, and data provided. We generally operate in a “just in time” fashion, meaning we procure specimens from our suppliers and distribute specimens to our customers after we obtain an order for specimens from a research client. Generally, we do not speculatively purchase and bank samples in anticipation of future, unspecified needs. We believe our approach offers many advantages over a more traditional inventory-based supplier business model where biorepositories take inventory risks, and where inventory turnover and cash conversion cycles can be lengthy.

Private Placement Offering

On December 1, 2021, we closed on a private placement offering (“PIPE”) for gross proceeds of approximately $21 million, before deducting approximately $1.4 million for underwriting discounts and commissions and estimated offering expenses, for (i) an aggregate of 1,749,999 shares of common stock and (ii) warrants, which are exercisable for an aggregate of up to 1,312,500 shares of common stock, all of which were repurchased by us on February 13, 2024, and are no longer outstanding.

At the Market Offering

On March 5, 2024, we entered into an At the Market Offering Agreement (the “ATM Agreement”) with Rodman & Renshaw LLC as agent (the “Sales Agent”) pursuant to which we may issue and sell shares of our common stock, having an aggregate offering price of up to $1,500,000 (the “ATM Shares”), from time to time through the Sales Agent (the “ATM Offering”). The ATM Shares, when issued, will be registered pursuant to our shelf registration statement on Form S-3 (File No 333-265976), which became effective on July 12, 2022. We intend to sell the ATM Shares, from time to time, pursuant to the ATM Agreement, in transactions that are “at the market offerings” as defined in Rule 415(a)(4) promulgated under the Securities Act. During the three months ended March 31, 2024, we issued 337,970 shares of common stock for gross proceeds of approximately $138,000 under the ATM Agreement. In connection with the ATM Offering, we incurred offering costs of approximately $205,000, resulting in a net cost of approximately $67,000.

Impact of the Current Economy

The Company’s financial performance is subject to global economic conditions and their impact on levels of spending by our customer research organizations, particularly discretionary spending for procurement of specimens used for research. Economic recessions may have adverse consequences across industries, including the health and biospecimen industries, which may adversely affect our business and financial condition. We increased our allowance for doubtful accounts in accounts receivables by $197,924 during the three months ended March 31, 2024 due to certain boutique life sciences customers either lacking liquidity or having filed for bankruptcy. We have enhanced procedures related to our credit check process for new and existing customers in fiscal year 2023 to mitigate the risk to future collectability of receivables.

Changes in general market, economic and political conditions in domestic and foreign economies or financial markets, including fluctuation in stock markets resulting from, among other things, trends in the economy and inflation, as are being currently experienced, may result in a reduction in researchers’ demand for specimens due to the research organization’s inability to obtain funding.

To further address the current market conditions, we have taken steps, which include but are not limited to, reevaluating our pricing in order to be more competitive, creating campaigns to highlight and fast-track high demand items, enhancing internal team communications to accelerate the sales cycle, moving to a new line of business structure organized by our internal categorization of biospecimen suppliers capabilities to increase efficiency in operations, implementation of next day quotes to increase conversion ratios of quotes to purchase orders, and initiation of efforts to decrease expenditures through reductions in our workforce.

We believe that our business will continue to be resilient through a continued industry-wide economic slowdown in life science research, and that we will continue to work on improving our liquidity to address our financial obligations and alleviate possible adverse effects on our business, financial condition, results of operations or prospects.

Impact of the Russian-Ukrainian War on Our Operations

Our business was negatively impacted during the first half of 2022 by the ongoing war between Russia and Ukraine. At the start of the war, we had approximately $1 million of purchase orders that were slated to be fulfilled by our supply network in Ukraine and Russia. This supply network was shut down at the start of the war. Ukrainian suppliers were disabled due to war conditions and evacuations and some of our Russian suppliers were disabled by sanctions. While we mobilized to shift these purchase orders to other suppliers in the network, the process of specimen collections from other supply sites took time, which caused a delay in the fulfillment of such purchase orders. Alternate suppliers do not have the same favorable unit economics or specimen collection rates, and this also impacted our margins. Additionally, key resources were diverted from operations to resolving the re-fulfillment issues caused by the conflict.

As of March 31, 2024, our supply sites in Russia that had not been under sanctions were accessible and our supply sites in Ukraine were mostly reopened. However, logistics and transportation of specimens out of the country of Ukraine remains challenging and not as economically feasible as they were prior to the beginning of the war. Due to the uncertainty caused by the ongoing war, Ukrainian and Russian suppliers may again become inaccessible to us. Therefore, as long as the uncertainty continues, our policy is to ensure at a purchase order level that an order is not solely sourced from the two countries. The short and long-term implications of the war are difficult to predict as of the date of this Quarterly Report. The imposition of more sanctions and countersanctions may have an adverse effect on the economic markets generally and could impact our business and the businesses of our supply partners, especially those in Ukraine and Russia. Because of the highly uncertain and dynamic nature of these events, it is not currently possible to estimate the impact of the war on our business and the companies from which we obtain supplies and distribute specimens.

Known Trends, Demands, Commitments, Events or Uncertainties Impacting Our Business

Chief Executive Officer Initiatives

The Company’s mission remains to accelerate life sciences research and development, pursuant to a single global marketplace platform. Executive management of the Company continues to review the Company’s structure, processes, and resources to evaluate and identify areas for improvement, and has been focused on creating and ensuring a runway for growth and scale for the business.

Throughout the year ended December 31, 2023 and in the first quarter of 2024, we initiated efforts to decrease our capital and operation expenditures by cutting costs and right sizing the Company through reductions in our workforce while streamlining operations and rationalizing resources to focus on key market opportunities. As a result, we began to experience significant decreases in expenditures starting in the second half of 2023. The reductions in workforce resulted in an estimated reduction in compensation costs of approximately 41% and technology costs of approximately 66% in the quarter ended March 31, 2024, when compared to the quarter ended March 31, 2023.

One of our key new revenue enhancement initiatives is to identify, through sequencing, high value cancer patients which possess specific mutations in donor Formalin-Fixed Paraffin-Embedded (“FFPE”) blocks. We have invested in active repetitive screening to create a virtual inventory of availability for our research customers in areas of high value. This initiative is extremely valuable, not only to our business, but we believe, for the entire industry. We have entered into contracts with qualified suppliers to provide specific high value FFPE blocks which, we believe, could result in significant revenue share options. The power of our supplier network makes this initiative possible and when paired with the search functionality of our proprietary iSpecimen Marketplace, it provides an easier solution than what currently exists in our industry. We formally launched this initiative towards the end of the third quarter of 2023 and have recognized a modest level of revenue since then. We own the data generated from sequencing of the FFPE blocks, and we are now creating a database of research content of our specific high value sequenced data that, we believe, will generate additional reiterative revenue by selling to researchers access to the database.

Our iSpecimen Marketplace Onsite Program, which offers additional support to our biospecimen supplier partners, is underway and we have appointed iSpecimen Marketplace Onsite coordinators, whose responsibility is to field all requests made by the supplier partner and submit proposals on behalf of the supplier partner, resulting in the acceleration of fulfillment with streamlined sample-related management and reduced strain on existing supplier staff and product pipelines.

During the three months ended March 31, 2024, we have had ongoing operational process improvement activities to increase collaboration within and between departments. Beginning during the second quarter of 2023, we moved to a line of business structure organized by our internal categorization of biospecimen suppliers’ capabilities, which has increased efficiency in our operations and throughout the Company. Previously, it took an extended number of days to complete a feasibility study in order to provide a customer

quote, which negatively impacted the time to convert a quote to a purchase order. We completed the implementation of a next day quote system in the third quarter of 2023 and we have already started to see positive results, as evidenced by increased conversion ratios of quotes to purchase orders which contributed to the increased revenue results for the second half of 2023.

While we are committed to investing in and developing our technology, we plan to invest at a significantly lower level in 2024 when compared to 2023 while we focus on raising capital and growing our revenues through key market opportunities. During the three months ended March 31, 2024 and 2023, we capitalized approximately $275,000 and $1,540,000, respectively, of internally developed software costs. These investments have already resulted in meaningful progress which includes an updated search functionality, improved user interface, increased automation, and an enhanced matchmaking function of the iSpecimen Marketplace platform. We anticipate that these investments will increase revenue opportunities and result in operational efficiencies, positively impacting our liquidity, capital resources and results of operations in the future.

During the year ended December 31, 2023, while still onboarding new suppliers, we shifted to the quality of our network. We established business criteria that focus on supplier capabilities and revenue growth strategies as well as technology criteria for integrating onto our iSpecimen Marketplace platform and participating with us. We have been reengaging our suppliers in a more meaningful manner which assisted us in the implementation of our next day quote system. We now have a key supplier program whereby we proactively engage with the suppliers to promote our business through marketing campaigns and supplier organizations’ offerings.

Components of Our Results of Operations

Revenue

We generate revenue by procuring various specimens from hospitals, laboratories, and other supply sites, for our medical research customers using our proprietary software, the iSpecimen Marketplace, to identify, locate, and ultimately validate the required specimens to our customers’ requested specifications. The Company’s performance obligation is to procure a specimen meeting the customer specification(s) from a supplier, on a “best efforts” basis, for our customer at the agreed price per specimen as indicated in the customer contract with the Company. We do not currently charge suppliers or customers for the use of our proprietary software. Each customer will execute a material and data use agreement with the Company or agree to online purchase terms, each of which includes terms such as specimen and data use, shipment terms, payment and cancellation terms. These are then supplemented by purchase orders that specify specimen requirements including detailed inclusion/exclusion criteria, quantities to be collected, and pricing. Collectively, these customer agreements represent the Company’s contracts with its customer. Generally, contracts have fixed unit pricing. For certain specimen orders, a refundable customer deposit may be required prior to order fulfillment depending on project set-up requirements, presented as deferred revenue. The Company expects to recognize the deferred revenue within the next twelve months.

We recognize revenue over time, as we have created an asset with no alternative use and we have an enforceable right to payment for performance completed to date. At contract inception, we review a contract and related order upon receipt to determine if the specimen ordered has an alternative use to us. Generally, specimens ordered do not have an alternative future use to us and our performance obligation is satisfied when the related specimens are accessioned. We use an output method to recognize revenue for specimens with no alternative future use. The output is measured based on the number of specimens accessioned.

Customers are typically invoiced upon shipment. Depending on the quantity of specimens ordered, it may take several accounting periods to completely fulfill a purchase order. In other words, there can be multiple invoices issued for a single purchase order, reflecting the specimens being accessioned over time. However, specimens are generally shipped as soon as possible after they have been accessioned.

Cost of Revenue

Cost of revenue primarily consists of the purchase price to acquire specimens from hospitals and laboratories, inbound and outbound shipping costs, supply costs related to samples, payment processing and related transaction costs, costs paid to the supply sites to support sample collections, amortization of capitalized sequenced data costs and other assets related to sequenced data. Shipping costs upon receipt of products from suppliers are recognized in cost of revenue.

26

Technology

Technology costs include consulting fees, payroll and related expenses for employees involved in the development and implementation of our technology, software license and system maintenance fees, outsourced data center costs, data management costs, amortization of internally developed software, and other expenses necessary to support technology initiatives. Collectively, these costs reflect the efforts we make to offer a wide variety of products and services to our customers. Technology and data costs are generally expensed as incurred.

A portion of technology costs are related to research and development. Costs incurred for research and development are expensed as incurred, except for software development costs that are eligible for capitalization. Research and development costs primarily include salaries and related expenses, in addition to the cost of external service providers.

Sales and Marketing

Sales and marketing costs primarily consist of payroll and related expenses for personnel engaged in marketing and selling activities, including salaries and sales commissions, travel expenses, public relations, and social media costs, ispecimen.com website development and maintenance costs, search engine optimization fees, advertising costs, direct marketing costs, trade shows and events fees, marketing and customer relationship management software, and other marketing-related costs.

Supply Development

We have agreements with supply partners that allow us to procure specimens from them and distribute these samples to customers. Supply development costs primarily include payroll and related expenses for personnel engaged in the development and management of this supply network, related travel expenses, regulatory compliance costs to support the network, and other supply development and management costs.

Fulfillment

Fulfillment costs primarily consist of those costs incurred in operating and staffing operations and customer service teams, including costs attributable to assess the feasibility of specimen requests, creating and managing orders, picking, packaging, and preparing customer orders for shipment, responding to inquiries from customers, and laboratory equipment and supplies.

General and Administrative

General and administrative expenses primarily consist of costs for corporate functions, including payroll and related expenses for human resources, legal, finance, and executive teams, associated software licenses, facilities, and equipment expenses, such as depreciation and amortization expense and rent, outside legal expenses, insurance costs, and other general and administrative costs.

Revenue

Revenue decreased by approximately $660,000, or 22%, from approximately $2,950,000 for the three months ended March 31, 2023 to approximately $2,290,000 for the three months ended March 31, 2024. This was primarily due to a decrease of 3,388, or approximately 39%, in specimen count from 8,629 specimens in the three months ended March 31, 2023 to 5,241 specimens in the three months ended March 31, 2024. The effect of the decrease in specimen count was partially offset by a change in the specimen mix which caused the average selling price per specimen to increase by approximately $95, or 28%, from approximately $342 in the three months ended March 31, 2023 to approximately $437 in the three months ended March 31, 2024.

Cost of Revenue

Cost of revenue decreased by approximately $147,000, or 13%, from approximately $1,147,000 for the three months ended March 31, 2023 to approximately $1,000,000 for the three months ended March 31, 2024, which was attributable to an approximately 39% decrease in the number of specimens accessioned for the current period compared to the same period in the prior year, partially offset by an approximately $58, or 44%, increase in the average cost per specimen.

Technology

Technology expenses increased by approximately $78,000, or 9%, from approximately $834,000 for the three months ended March 31, 2023 to approximately $912,000 for the three months ended March 31, 2024. The increase was related to increases in amortization of internally developed software of approximately $99,000, professional fees of approximately $11,000, and general operating expenses of approximately $1,000, which were partially offset by decreases in headcount and payroll and related expenses of approximately $33,000.

28

Sales and Marketing Expenses

Sales and marketing expenses decreased by approximately $296,000, or 31%, from approximately $962,000 for the three months ended March 31, 2023 to approximately $666,000 for the three months ended March 31, 2024. The decrease was primarily attributable to decreases in payroll and related expenses of approximately $217,000, external marketing expense of approximately $95,000, and general operating expenses related to sales and marketing of approximately $20,000, which were partially offset by an increase in advertising and promotions expense of approximately $36,000.

Supply development expenses decreased by approximately $77,000, or 28%, from approximately $275,000 for the three months ended March 31, 2023 to approximately $198,000 for the three months ended March 31, 2024. The decrease was primarily attributable to decreases in payroll and related expenses of approximately $37,000, professional fees of approximately $31,000, and general supply development expenses of approximately $9,000.

Fulfillment

Fulfillment costs decreased by approximately $45,000, or 10%, from approximately $456,000 for the three months ended March 31, 2023 to approximately $411,000 for the three months ended March 31, 2024. The decrease was primarily attributable to decreases in professional fees of approximately $27,000, payroll and related expenses of approximately $10,000 for personnel engaged in pre-sales feasibility assessments and order fulfillment, and general operating expenses related to fulfillment of approximately $8,000.

General and Administrative Expenses

General and administrative expenses increased by approximately $286,000, or 16%, from approximately $1,818,000 for the three months ended March 31, 2023 to approximately $2,104,000 for the three months ended March 31, 2024. The increase was attributable to increases in professional fees of approximately $329,000, taxes and insurance of approximately $267,000, and bad debt expense of approximately $45,000, which were partially offset by decreases in compensation costs of approximately $250,000, general operating expenses of approximately $78,000, depreciation and amortization of approximately $23,000, and utilities and facilities expenses of approximately $4,000.

Other Income, net

Other income, net, decreased by approximately $12,000, or 11%, from approximately $111,000 for the three months ended March 31, 2023 to approximately $98,000 for the three months ended March 31, 2024. The decrease in other income, net, was attributable to a decrease in interest income of approximately $84,000 and an increase in interest expense of approximately $1,000, partially offset by an increase in other income of approximately $72,000.

Capital Resources

We have had recurring losses since inception. As of March 31, 2024, our available cash and available-for-sale securities totaled approximately $2,556,000, which represented a decrease of approximately $2,450,000 from approximately $5,006,000, as of December 31, 2023. We had negative working capital of approximately $415,000, an accumulated deficit of approximately $62,267,000, cash and cash equivalents and short-term investments of approximately $2,556,000, and accounts payable and accrued expenses of approximately $5,271,000. Our continued viability is dependent on the ability to successfully obtain additional working capital and/or ultimately attain profitable operations. During the year ended December 31, 2023 and the first quarter of 2024, we executed reductions in workforce, resulting in an estimated reduction in monthly compensation costs of approximately 41% in the three months ended March 31, 2024 when compared to the quarter ended March 31, 2023, after streamlining operations and rationalizing resources to focus on key market opportunities. We plan to add additional customers and suppliers to increase and add additional revenues through our new revenue enhancement projects as well as to reduce and manage expenditures to improve our financial position and ensure continued funding of operations. However, as certain elements of our operating plan are not within our control, we are unable to assess their probability. We may also seek to fund our operations through public equity or debt financing, as well as other sources.

On March 5, 2024, we put in place an ATM Agreement which may allow us to issue and sell shares of our common stock, having an aggregate offering price of up to $1,500,000, from time to time through the Sales Agent. During the three months ended March 31, 2024, we sold 337,970 shares of common stock for gross proceeds of approximately $138,000 under the ATM Agreement. We incurred offering costs of approximately $205,000 resulting in a net cost of approximately $67,000.

We may be unsuccessful in increasing our revenues from our new enhancement project or contain our operating expenses, or we may be unable to raise additional capital on commercially favorable terms. Our failure to generate additional revenues or contain operating costs would have a negative impact on our business, results of operations and financial condition and our ability to continue as a going concern. If we do not generate enough revenue to provide an adequate level of working capital, our business plan will be scaled down further.

These conditions raise substantial doubt regarding our ability to continue as a going concern for a period of one year after the date of this Quarterly Report. Management’s plan to mitigate the conditions that raise substantial doubt includes generating additional revenues through its revenue enhancement projects, deferring certain projects and capital expenditures and eliminating certain future operating expenses for us to continue as a going concern. However, there can be no assurance that we will be successful in completing any of these options. As a result, management’s plans cannot be considered probable and thus do not alleviate substantial doubt about our ability to continue as a going concern.

Cash Flows

Operating Activities

For the three months ended March 31, 2024, net cash used in operating activities was approximately $2,072,000, which consisted of a net loss of approximately $2,902,000 offset by non-cash charges of approximately $861,000, which included approximately $533,000 related to amortization of internally developed software, approximately $198,000 in bad debt expense, approximately $94,000 in stock-based compensation, approximately $48,000 related to amortization of other intangible assets, and approximately $16,000 related to depreciation of property and equipment, which were offset by approximately $27,000 of accretion of discount on available-for-sale securities.

30

Total changes in assets and liabilities of approximately $31,000 were attributable to an approximately $365,000 decrease in accounts payable, an approximately $143,000 decrease in deferred revenue, an approximately $40,000 decrease in operating lease liability, and an approximately $22,000 increase in prepaid expenses and other current assets, offset by an approximately $234,000 decrease in accounts receivable-unbilled, an approximately $170,000 increase in accrued expenses, an approximately $93,000 decrease in accounts receivable, and an approximately $41,000 decrease in operating lease right-of-use asset.

For the three months ended March 31, 2023, net cash used in operating activities was approximately $2,826,000, which consisted of a net loss of approximately $2,432,000 offset by non-cash charges of approximately $745,000, which included approximately $433,000 related to amortization of internally developed software, approximately $153,000 in bad debt expense, approximately $121,000 in stock-based compensation, and approximately $39,000 related to depreciation of property and equipment.

Total changes in assets and liabilities of approximately $1,140,000 were attributable to an approximately $1,561,000 increase in accounts receivable, an approximately $623,000 decrease in accrued expenses, an approximately $38,000 decrease in operating lease liability, an approximately $35,000 decrease in deferred revenue, and an approximately $12,000 increase in prepaid expenses and other current assets, offset by an approximately $743,000 decrease in accounts receivable-unbilled, an approximately $242,000 increase in accounts payable, an approximately $106,000 decrease in tax credit receivable, and an approximately $39,000 decrease in operating lease right-of-use asset.

Investing Activities

Net cash provided by investing activities was approximately $1,937,000 for the three months ended March 31, 2024, which consisted of approximately $2,683,000 of proceeds from sales and maturities of available-for-sale securities, which were offset by approximately $461,000 of purchases of available-for-sale securities, approximately $275,000 of capitalization of internally developed software, and approximately $9,000 of purchase of property and equipment.

Net cash used in investing activities was approximately $8,788,000 for the three months ended March 31, 2023, which consisted of approximately $7,241,000 of purchase of available-for-sale securities, approximately $1,540,000 of capitalization of internally developed software, and approximately $8,000 of purchase of property and equipment.

Financing Activities

Net cash used in financing activities was approximately $119,000 for the three months ended March 31, 2024, which consisted of approximately $205,000 for the payment of offering costs in connection with the issuance of common stock in connection with the ATM Offering and approximately $53,000 for the repurchase of common stock exercisable under PIPE Warrants, offset by approximately $138,000 of proceeds received from the issuance of common stock in connection with the ATM Offering.

Net cash provided by financing activities was approximately $68,000 for the three months ended March 31, 2023, due to proceeds received from the exercise of stock options.

Effects of Inflation and Supply Chain Shortages

Our operations are heavily reliant on specimen availability, and as a result, we often receive more requests than we can fulfill. While the Company is subject to these types of supply chain constraints that are specific to the specimen industry, we have not been materially affected by the more common supply chain issues currently affecting the economy, specifically surrounding transportation. Due to the small size of the packages that we ship, our carriers were able to continue making timely deliveries during the three months ended March 31, 2024. However, there had been an increase in our shipping costs period over period during the three months ended March 31, 2024.

We have experienced negative effects of inflation in certain areas of our business due to the high rates of inflation in the world’s current economy. This inflation is affecting employee salaries, which account for a significant portion of our operating costs. Additionally, the costs of supplies have been affected by inflation; however, these costs are not significant to the Company’s results.

Inflation has not had a significant impact on the cost of specimens due to our long-term contracts maintained with vendors, which include revenue sharing plans.

31

Critical Accounting Policies and Estimates

We have chosen accounting policies that we believe are appropriate to accurately and fairly report our operating results and financial condition in conformity with GAAP. We apply these accounting policies in a consistent manner. Our significant accounting policies are discussed in Note 2, “Summary of Significant Accounting Policies,” in our financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2023.

The application of critical accounting policies requires that we make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures. These estimates and assumptions are based on historical experience and other market-specific or other relevant assumptions that we believe to be reasonable under the circumstances. We evaluate these estimates and assumptions on an ongoing basis. If actual results ultimately differ from previous estimates, the revisions are included in results of operations in the period in which the actual amounts become known. The critical accounting policies that involve the most significant management judgments and estimates used in preparation of our unaudited condensed financial statements or are the most sensitive to change from outside factors, are discussed in “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. There have been no material changes in our critical accounting policies and procedures during the three months ended March 31, 2024.

JOBS Act Transition Period

On April 5, 2012, the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) was enacted. Section 107 of the JOBS Act provides that an “emerging growth company” 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. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies.

We have elected not to “opt out” of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we will adopt the new or revised standard at the time private companies adopt the new or revised standard and will do so until such time that we either (i) irrevocably elect to “opt out” of such extended transition period or (ii) no longer qualify as an emerging growth company.

We are in the process of evaluating the benefits of relying on other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, as an “emerging growth company,” we intend to rely on certain of these exemptions, including without limitation, (i) providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002 and (ii) complying with any requirement that may be adopted by the PCAOB regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor discussion and analysis. We will remain an “emerging growth company” until the earliest of (i) the last day of the fiscal year in which we have total annual gross revenues of $1.235 billion or more; (ii) December 31, 2026; (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the SEC.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Not applicable for smaller reporting companies.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the fiscal quarter ended March

32

31, 2024, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. These controls and procedures are designed to provide reasonable assurance that the information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial and accounting officer, in a manner to allow timely decisions regarding required disclosures. Based on this evaluation, management has concluded that our disclosure controls and procedures were not effective as of March 31, 2024 due to the following material weakness in internal control over financial reporting:

● The Company did not design and maintain adequate controls to maintain appropriate documentation for the tax-exempt status of its customers, calculate and collect sales tax at point of sale, and subsequently report and remit in a timely manner to the relevant tax jurisdictions sales tax obligations.

Notwithstanding the existence of the material weakness described above, management believes that the unaudited condensed financial statements included in this Quarterly Report fairly present, in all material respects, our financial position, results of operations and cash flows as of and for the periods presented, in conformity with GAAP.

Management’s Plan for Remediation

The material weakness described above was identified as a result of an entity-wide risk assessment process that commenced in the quarter ended June 30, 2023. The Company is in the process of implementing a remediation plan to improve our internal control over financial reporting and to remediate the related control deficiencies that led to the material weakness. In response to these deficiencies, management, with the oversight of the Audit Committee of the Board of Directors, has identified and implemented steps to remediate the material weakness.

The Company began implementing the remediation plan during the second quarter of fiscal year 2023 and this remediation is ongoing as of the filing date of this Quarterly Report. The following remedial measures are designed to address the material weakness and to continue to improve our internal control over financial reporting.

● We have engaged external tax advisors to complement internal resources and efforts and provide support in assessing the appropriate sales tax treatment associated with the Company’s products for all prior years in which the Company had generated revenue.

● We have begun obtaining sales tax exemption letters, representation letters or proof of payments of compensating use tax from our customers and we have started a collection effort of these sales taxes from certain customers who have notified the Company that they do not have a sales tax exemption letter.

● We have begun implementing a sales tax software platform solution for the calculation, collection, and remittance of sales tax for all non-exempt future sales, and assisting with the collection and tracking of VDAs received from states where a potential sales tax liability may exist.

● We have begun designing and implementing enhanced policies, procedures and controls related to the calculation, communication, collection, and remittance of sales tax to relevant jurisdictions.

● We have begun training appropriate personnel in the effective design and execution of our enhanced policies, procedures, and controls, including the importance of the ongoing, consistent effective execution of such procedures and controls.

We are committed to the remediation of the material weakness and expect to successfully implement enhanced control processes. However, as we continue to evaluate, and work to improve our internal control over financial reporting, management may determine that additional measures to address control deficiencies or modifications to the remediation plan are necessary. Therefore, we cannot assure you when we will be able to fully remediate such weakness, nor can we be certain that additional actions will not be required or what the costs may be of any such additional actions. Moreover, we cannot assure you that additional material weaknesses will not arise in the future.

Changes in Internal Control Over Financial Reporting

We are in the process of implementing certain changes to our internal controls to remediate the material weakness described above. Except as noted above, there were no changes in the Company’s internal control over financial reporting during the three months ended March 31, 2024 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

NATURE OF BUSINESS

NATURE OF BUSINESS

1.NATURE OF BUSINESS AND BASIS OF PRESENTATION

Business

iSpecimen Inc. (“iSpecimen” or the “Company”) was incorporated in 2009 under the laws of the state of Delaware. The Company has developed and launched a proprietary online marketplace platform that connects medical researchers who need access to subjects, samples, and data, with hospitals, laboratories, and other organizations who have access to them. iSpecimen is a technology-driven company founded to address a critical challenge: how to connect life science researchers who need human biofluids, tissues, and living cells (“biospecimens”) for their research, with biospecimens available (but not easily accessible) in healthcare provider organizations worldwide. The Company’s proprietary platform, the iSpecimen Marketplace platform, was designed to solve this problem and transform the biospecimen procurement process to accelerate medical discovery. The Company is headquartered in Lexington, Massachusetts and its principal market is North America. The Company operates as one operating and reporting segment.

Basis of Presentation

The accompanying unaudited condensed financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) as determined by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) for interim financial information, and, pursuant to the rules and regulations of Article 10 of Regulation S-X of the Securities Act of 1933, as amended (the “Securities Act”), published by the Securities and Exchange Commission (“SEC”) for interim financial statements. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the unaudited condensed financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results of operations for the periods presented. They may not include all of the information and footnotes required by GAAP for complete financial statements. Therefore, these unaudited condensed financial statements should be read in conjunction with the Company’s audited financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

Going Concern Uncertainty and Management’s Plan

The Company has recognized recurring losses since inception. As of March 31, 2024, the Company had negative working capital of $414,722, an accumulated deficit of $62,266,929, cash and cash equivalents and short-term investments of $2,556,384, and accounts payable and accrued expenses of $5,271,289. Since inception, the Company has relied upon raising capital and its revenues to finance operations.

The future success of the Company is dependent on its ability to successfully obtain additional working capital and/or to ultimately attain profitable operations. The Company has initiated efforts to decrease its capital and operational expenditures by cutting costs and right sizing the Company through reductions in workforce. During the year ended December 31, 2023 and the first quarter of 2024, the Company executed reductions in workforce, resulting in an estimated reduction in monthly compensation costs of approximately 41% and technology costs of approximately 66% in the three months ended March 31, 2024, after streamlining operations and rationalizing resources to focus on key market opportunities. In addition, the Company plans to add additional customers and suppliers to increase and add additional revenues through its new revenue enhancement projects as well as to reduce and manage expenditures to improve its financial position and ensure continued funding of operations. However, as certain elements of the Company’s operating plan are not within the Company’s control, the Company is unable to assess their probability of success. The Company may also seek to fund its operations through public equity or debt financing, as well as other sources.

On March 5, 2024, the Company put in place an At the Market Offering Agreement (the “ATM Agreement”) which may allow the Company to issue and sell shares of its common stock, having an aggregate offering price of up to $1,500,000 (the “ATM Shares”), from time to time through the Sales Agent (as defined below under Note 9). During the three months ended March 31, 2024, the Company sold 337,970 shares of common stock for gross proceeds of approximately $138,000 under the ATM Agreement. The Company incurred offering costs of approximately $205,000 resulting in a net cost of approximately $67,000.

The Company may be unsuccessful in increasing its revenues from its new enhancement projects or contain its operating expenses, or it may be unable to raise additional capital on commercially favorable terms. The Company’s failure to generate additional revenues or contain operating costs would have a negative impact on the Company’s business, results of operations and financial condition and the Company’s ability to continue as a going concern. If the Company does not generate enough revenue to provide an adequate level of working capital, its business plan will be scaled down further.

These conditions raise substantial doubt regarding the Company’s ability to continue as a going concern for a period of one year from the date these unaudited condensed financial statements are issued. Management’s plan to mitigate the conditions that raise substantial doubt includes generating additional revenues through its revenue enhancement projects, deferring certain projects and capital expenditures and eliminating certain future operating expenses for the Company to continue as a going concern. However, there can be no assurance that the Company will be successful in completing any of these options. As a result, management’s plans cannot be considered probable and thus do not alleviate substantial doubt about the Company’s ability to continue as a going concern.

The accompanying unaudited condensed financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The unaudited condensed financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described above.

Impact of the Current Economy

The Company’s financial performance is subject to global economic conditions and their impact on the levels of spending by its customer research organizations, particularly discretionary spending for procurement of specimens used for research. Economic recessions may have adverse consequences across industries, including the health and biospecimen industries, which may adversely affect the Company’s business and financial condition. The Company increased its allowance for doubtful accounts in accounts receivables by $197,924 during the three months ended March 31, 2024 due to certain boutique life sciences customers either lacking liquidity or having filed for bankruptcy. The Company has enhanced procedures related to its credit check process for new and existing customers to mitigate the risk to future collectability of receivables.

Changes in general market, economic and political conditions in domestic and foreign economies or financial markets, including fluctuation in stock markets resulting from, among other things, trends in the economy and inflation, as are being currently experienced, may result in a reduction in researchers’ demand for specimens due to the research organization’s inability to obtain funding.

To further address the current market conditions, the Company has taken steps, that include, but are not limited to, reevaluating its pricing in order to be more competitive, creating campaigns to highlight and fast-track high demand items, enhancing internal team communications to accelerate the sales cycle, moving to a new line of business structure organized by its internal categorization of biospecimen suppliers’ capabilities to increase efficiency in operations, implementation of next day quotes to increase conversion ratios of quotes to purchase orders, and initiation of efforts to decrease expenditures through reductions in workforce.  

The Company believes that its business will continue to be resilient through a continued industry-wide economic slowdown in life science research, and that the Company has and will continue to work on improving liquidity to address its financial obligations and alleviate possible adverse effects on its business, financial condition, results of operations or prospects.

Impact of the Russian-Ukrainian War on the Company’s Operations

The Company’s business was negatively impacted during the first half of 2022 by the ongoing war between Russia and Ukraine. At the start of the war, the Company had approximately $1 million of purchase orders that were slated to be fulfilled by the Company’s supply network in Ukraine and Russia. This supply network was shut down at the start of the war. Ukrainian suppliers were disabled due to war conditions and evacuations and some of the Company’s Russian suppliers were disabled by sanctions. While the Company mobilized to shift these purchase orders to other suppliers in the network, the process of specimen collections from other supply sites took time, which caused a delay in the fulfillment of such purchase orders. Alternate suppliers do not have the same favorable unit

economics or specimen collection rates, and this also impacted the Company’s margins. Additionally, key resources were diverted from operations to resolving the re-fulfillment issues caused by the conflict.

As of March 31, 2024, the Company’s supply sites in Russia that had not been under sanctions were accessible and the Company’s supply sites in Ukraine were mostly reopened. However, logistics and transportation of specimens out of the country of Ukraine remains challenging and not as economically feasible as they were prior to the beginning of the war. Due to the uncertainty caused by the ongoing war, Ukrainian and Russian suppliers may again become inaccessible to the Company. Therefore, as long as the uncertainty continues, the Company’s policy is to ensure at a purchase order level that an order is not solely sourced from the two countries. The short and long-term implications of the war are difficult to predict as of the filing date of the Company’s Quarterly Report on Form 10-Q in which these unaudited condensed financial statements are included (the “Quarterly Report”). The imposition of more sanctions and countersanctions may have an adverse effect on the economic markets generally and could impact the Company’s business and the businesses of the Company’s supply partners, especially those in Ukraine and Russia. Because of the highly uncertain and dynamic nature of these events, it is not currently possible to estimate the impact of the war on the Company’s business and the companies from which the Company obtains supplies and distributes specimens.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company’s significant accounting policies and recent accounting standards are summarized in Note 2 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. There were no significant changes to these accounting policies during the three months ended March 31, 2024.

Use of Estimates

The preparation of the Company’s unaudited condensed financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Company utilizes certain estimates in the determination of the deferred tax valuation allowances, revenue recognition, stock-based compensation, allowance for doubtful accounts, accrued expenses, and the useful lives of internally developed software and sequenced data. The Company bases its estimates on historical experience and other market-specific or other relevant assumptions that it believes to be reasonable under the circumstances. Actual results could differ from such estimates.

Investments

The Company’s investments are considered to be available-for-sale as defined under ASC 320, Investments – Debt Securities, and are recorded at fair value. Unrealized gains and losses are included in accumulated other comprehensive income. Purchases and sales of securities are reflected on a trade-date basis. Realized gains or losses are released from accumulated other comprehensive income and into earnings on the statement of operations, and amortization of premiums and accretion of discounts on the U.S treasury bills are recorded in interest expense or income, respectively.

The Company continually monitors the difference between its cost basis and the estimated fair value of its investments. The Company’s accounting policy for impairment recognition requires other-than-temporary impairment charges to be recorded when it determines that it is more likely than not that it will be unable to collect all amounts due according to the contractual terms of the fixed maturity security or that the anticipated recovery in fair value of the equity security will not occur in a reasonable amount of time. Impairment charges on investments are recorded based on the fair value of the investments at the measurement date or based on the value calculated using a discounted cash flow model. Credit-related impairments on fixed maturity securities that the Company does not plan to sell, and for which it is not more likely than not to be required to sell, are recognized in net income. Any non-credit related impairment is recognized as a component of other comprehensive income. Factors considered in evaluating whether there is a decline in value include: the length of time and the extent to which the fair value has been less than cost; the financial condition and near-term prospects of the issuer; and the likelihood that it will be required to sell the investment.

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability of fair value measures, the following hierarchy prioritizes the inputs to valuation methodologies used to measure fair value:

● Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets.

● Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

● Level 3 — Valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.

For certain financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable, the carrying amounts approximate their fair values as of March 31, 2024 and December 31, 2023, respectively, because of their short-term nature. Available-for-sale securities are recorded at fair value and as level 1 investments.

Revenue Recognition and Accounts Receivable

The Company recognizes revenue using the five-step approach as follows: (1) identify the contract with the customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when (or as) the Company satisfies the performance obligations.

The Company generates revenue by procuring various specimens from hospitals, laboratories, and other supply sites, for the Company’s medical research customers using the Company’s proprietary software, the iSpecimen Marketplace, to identify, locate, and ultimately validate the required specimens to the Company’s customers’ requested specifications. The Company’s performance obligation is to procure a specimen meeting the customer’s specification(s) from a supplier, on a “best efforts” basis, for the Company’s customer at the agreed price per specimen as indicated in the customer’s contract with the Company. The Company does not currently charge suppliers or customers for the use of the Company’s proprietary software. Each customer will execute a material and data use agreement with the Company or agree to online purchase terms, each of which includes terms such as specimen and data use, shipment terms, payment, and cancellation terms. These are then supplemented by purchase orders that specify specimen requirements including detailed inclusion/exclusion criteria, quantities to be collected, and pricing. Collectively, these customer agreements represent the Company’s contracts with its customer. Generally, contracts have fixed unit pricing. For certain specimen orders, a refundable customer deposit may be required prior to order fulfillment depending on project set-up requirements, which is presented as deferred revenue. The Company expects to recognize the deferred revenue within the next twelve months.

Specimen collections occur at supply sites within the Company’s network. “Collection” is when the specimen has been removed, or “collected” from the patient or donor. A specimen is often collected specifically for a particular Company order. Once collected, the specimen is assigned by the supplier to the Company and control of the specimen passes to the Company. “Accession” is the process whereby a collected specimen and associated data are registered and assigned in the iSpecimen Marketplace to a particular customer order, which can occur while a specimen is at the supplier site or while at the Company site and it is when control of the specimen passes to the customer. Suppliers may ship specimens to the Company or directly to the customer if specimens must be delivered within a short time period (less than 24 hours after collection) or shipping to the Company is not practical.

The Company has evaluated principal versus agent considerations as part of the Company’s revenue recognition policy. The Company has concluded that it acts as principal in the arrangement as it manages the procurement process from beginning to end and determines which suppliers will be used to fulfill an order, usually takes physical possession of the specimens, sets prices for the specimens, and bears the responsibility for customer credit risk.

The Company recognizes revenue over time, as the Company has created an asset with no alternative use to the Company, which has an enforceable right to payment for performance completed to date. At contract inception, the Company reviews a contract and related order upon receipt to determine if the specimen ordered has an alternative use by the Company. Generally, specimens ordered do not have an alternative future use to the Company and the performance obligation is satisfied when the related specimens are accessioned. The Company uses an output method to recognize revenue for specimens with no alternative future use. The output is measured based on the number of specimens accessioned. In the rare circumstances where specimens do have an alternative future use, the Company's performance obligation is satisfied at the time of shipment.

Customers are generally invoiced upon shipment. Depending on the quantity of specimens ordered, it may take several accounting periods to completely fulfill a purchase order. In other words, there can be multiple invoices issued for a single purchase order, reflecting the specimens being accessioned over time. However, specimens are generally shipped as soon as possible after they have been accessioned.

Once a specimen that has no alternative future use and for which the Company has an enforceable right to payment has been accessioned, the Company records the offset to revenue in accounts receivable – unbilled. Once the specimen has been shipped and invoiced, a reclassification is made from accounts receivable - unbilled to accounts receivable.

Customers are generally given fourteen days from the receipt of specimens to inspect the specimens to ensure compliance with specifications set forth in the purchase order documentation. Customers are entitled to either receive replacement specimens or receive reimbursement of payments made for such specimens. The Company has a nominal history of returns for nonacceptance of specimens delivered. When this occurs, the Company gives the customer a credit for the returns. The Company has not recorded a returns allowance.

The following table summarizes the Company’s revenue for the three months ended March 31:

	2024		2023
Specimens - contracts with customers	$	2,136,100	$	2,712,376
Shipping and other		153,893		237,821
Revenue	$	2,289,993	$	2,950,197

The Company carries its accounts receivable at the invoiced amount less an allowance for doubtful accounts. On a periodic basis, the Company evaluates its accounts receivable to determine if an allowance for doubtful accounts is necessary, based on economic conditions and each customer’s payment history. Receivables are written off when deemed uncollectible, with any future recoveries recorded as income when received. As of March 31, 2024 and December 31, 2023, the Company had an allowance for doubtful accounts of $718,821 and $520,897, respectively.

The Company applies the practical expedient to account for shipping and handling activities as fulfillment cost rather than as a separate performance obligation. Shipping and handling costs incurred are included in cost of revenue.

Internally Developed Software, Net

The Company capitalizes certain internal and external costs incurred during the application development stage of internal-use software projects until the software is ready for its intended use. Amortization of the asset commences when the software is complete and placed into service and is recorded in operating expenses. The Company amortizes completed internal-use software over its estimated useful life of five years on a straight-line basis. Costs incurred during the planning, training and post-implementation stages of the software development life cycle are classified as technology costs and are expensed to operations as incurred.

Other Intangible Assets, Net

The Company procures data generated from sequencing of Formalin-Fixed Paraffin-Embedded (“FFPE”) blocks from a third-party sequencer which the Company licenses to its customers with the sale of FFPE blocks at an additional cost. The sequenced data is also organized to form a database of research content that is available for sale through a subscription model. The Company has determined that the sequenced data is an intangible asset and capitalizes the cost to procure the sequenced data. The sequenced data is amortized to

cost of revenue over an estimated useful life of five years on a straight-line basis. The costs paid to the third-party sequencer are the only costs capitalized and all other related costs are expensed to operations as incurred.

Impairment of Long-Lived Assets

Management reviews long-lived assets for impairment when circumstances indicate the carrying amount of an asset may not be recoverable. An impairment loss is recognized when expected cash flows are less than the asset’s carrying value. Long-lived assets consist of property and equipment, internal-use software and other intangible assets. No impairment charges were recorded for the three months ended March 31, 2024 and 2023.

Stock-Based Compensation

The Company records stock-based compensation for options granted to employees, non-employees, and to members of the board of directors for their services to the Company based on the grant date fair value of awards issued, and the expense is recorded on a straight-line basis over the requisite service period. Forfeitures are recognized when they occur.

The Company uses the Black-Scholes-Merton option pricing model to determine the fair value of stock options. The use of the Black-Scholes-Merton option pricing model requires management to make assumptions with respect to the expected term of the option, the expected volatility of the common stock consistent with the expected life of the option, risk-free interest rates and expected dividend yields of the common stock. The Company has concluded that its historical share option exercise experience does not provide a reasonable basis upon which to estimate expected term. Therefore, the expected term was determined according to the simplified method, which is the average of the vesting tranche dates and the contractual term. Due to the lack of Company-specific historical and implied volatility data, the estimate of expected volatility is primarily based on the historical volatility of a group of similar companies that are publicly traded. For these analyses, companies with comparable characteristics are selected, including enterprise value and position within the industry, and with historical share price information sufficient to meet the expected life of the stock-based awards. The Company computes the historical volatility data using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term of its stock-based awards.

The risk-free interest rate is determined by reference to U.S. Treasury zero-coupon issues with remaining maturities similar to the expected term of the options. The Company has not paid, and does not anticipate paying, cash dividends on shares of its common stock.

The fair value of the Company’s common stock is equal to the closing price on the specified grant date.

Restricted Stock Units (“RSUs”)

The Company recognizes stock-based compensation expense from RSUs ratably over the specified vesting period. The fair value of RSUs is determined to be the closing share price of the Company’s common stock on the grant date.

Common Stock Warrants

The Company accounts for common stock warrants as either equity instruments or liabilities, depending on the specific terms of the warrant agreement. The warrants shall be classified as a liability if 1) the underlying shares are classified as liabilities or 2) the entity can be required under any circumstances to settle the warrant by transferring cash or other assets. The measurement of equity-classified non-employee stock-based payments is generally fixed on the grant date and are considered compensatory. For additional discussion on warrants, see Note 9.

Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss applicable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by adjusting the weighted-average number of shares outstanding for the dilutive effect of common stock equivalents

outstanding for the period, determined using the treasury-stock method. Therefore, basic and diluted net loss per share applicable to common stockholders were the same for all periods presented.

The table below provides information on shares of the Company’s common stock issuable upon vesting and exercise, as of March 31:

	2024	2023
Shares issuable upon vesting of RSUs	96,788	216,058
Shares issuable upon exercise of stock options	350,062	330,788

Recently Adopted Accounting Standards

In June 2016, the FASB issued Accounting Standards Updates (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the impairment model for most financial assets and certain other instruments. For receivables, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowance for losses. In addition, an entity will have to disclose significantly more information about allowances and credit quality indicators. The new standard is effective for the Company for fiscal years beginning after December 15, 2022. The Company adopted this new standard as of January 1, 2023. ASU 2016-13 did not have a material impact on the Company’s unaudited condensed financial statements.

In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies an issuer’s accounting for convertible instruments by reducing the number of accounting models that require separate accounting for embedded conversion features. ASU 2020-06 also simplifies the settlement assessment that entities are required to perform to determine whether a contract qualifies for equity classification and makes targeted improvements to the disclosures for convertible instruments and earnings-per-share (EPS) guidance. This update will be effective for the Company’s fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Entities can elect to adopt the new guidance through either a modified retrospective method of transition or a fully retrospective method of transition. The Company adopted this new standard as of January 1, 2024. ASU 2020-06 did not have a material impact on the Company’s unaudited condensed financial statements.

Leases

The Company has one operating lease of office space in Lexington, Massachusetts, which was initially set to expire on February 28, 2024. The lease was renewed on September 27, 2023 to extend the lease term for a period of 12 months from February 29, 2024 through February 28, 2025. The lease renewal includes an option to terminate the lease before its expiration date if notice is provided to the lessor by June 30, 2024.

Leases with an initial term of twelve months or less are not recorded on the balance sheet date, and the Company does not separate lease and non-lease components of contracts. There are no material residual guarantees associated with any of the Company’s leases, and there are no significant restrictions or covenants included in the Company’s lease agreements.

The Company’s lease agreement does not provide an implicit borrowing rate. Therefore, the Company used a benchmark approach to derive an appropriate imputed discount rate. The Company benchmarked itself against other companies of similar credit ratings and comparable quality and derived an imputed rate, which was used to discount its real estate lease liabilities.

There was no sublease rental income for the three months ended March 31, 2024, and the Company is not the lessor in any lease arrangement, and there were no related-party lease agreements.

Sales Tax Payable

The majority of the Company’s customers are researchers, universities, hospitals, and not-for-profit entities that were believed by the Company to have a sales and use tax exemption that generally excludes them from paying sales taxes. The main types of specimens the Company sells are blood, blood plasma, human tissue, human parts, and human bodily fluids and only a few of these products are typically not taxable in some states regardless of the buyer’s tax exemption status. The Company historically has not collected sales tax in states where it had sales. Had the Company contemporaneously collected and remitted sales tax for all customers and in all jurisdictions where it would have been required, there would have been no material impact on the Company’s unaudited condensed financial statements.

As a result of an entity-wide risk assessment process that commenced in the second quarter of 2023, the Company engaged external tax consultant advisors to complement internal resources and efforts to provide support in assessing the appropriate sales tax treatment associated with the Company’s products for all prior years in which the Company had generated revenue, to assist with the facilitation and tracking of Voluntary Disclosure Agreements (“VDAs”) in jurisdictions where a potential tax liability may exist and to assist with the implementation of a sales tax software platform solution for the calculation, communication, collection, and remittance of sales tax for all non-exempt future sales.

From the Company’s inception through the filing date of this Quarterly Report, the Company now believes that an obligation to collect and remit sales tax existed for certain of its sales of products to certain of its customers. The Company has analyzed its product sales, on an invoice-by-invoice and customer-by-customer basis, to determine which products are subject to sales tax in each jurisdiction, and determining which of its customers are exempt from sales tax, and which customers who were not exempt from sales tax have already paid compensating use tax to the appropriate jurisdiction. Part of this process includes requesting and obtaining exemption letters or representations from its customers or proof of payment of their compensating use tax. As the Company continues to make progress on this project, certain customers have notified the Company that they are not exempt from the payment of sales tax and have not remitted use tax and the Company has started to invoice such customers for past sales tax due.  

As of March 31, 2024, the Company had accrued a sales tax liability of approximately $710,000 and the related interests and penalties of approximately $208,000 in accrued expenses on the balance sheet. The estimated liability represents the estimated tax liability for sales made to customers who have notified the Company that they are not exempt from sales taxes and customers who have not responded to the Company’s request to provide a sales exemption letter. As of March 31, 2024, the Company had recovered approximately $412,000 of prior taxes from certain customers who do not have a sales tax exemption. The Company continues to pursue those non-responsive customers and expects over time that further exemption letters or representations will be received that will reduce the liability. The Company did not recognize any additional loss in its statement of operations and comprehensive loss related to the sales tax liability during the three months ended March 31, 2024. The Company is in the process of commencing its VDA filings with relevant taxing jurisdictions regarding its noncompliance, during which it will remit its sales tax obligations.

Legal Proceedings

From time to time the Company is involved in litigation, claims, and other proceedings arising in the ordinary course of business. Such litigation and other proceedings may include, but are not limited to, actions relating to employment law and misclassification, intellectual property, commercial or contractual claims, or other consumer protection statutes. Litigation and other disputes are inherently

unpredictable and subject to substantial uncertainties and unfavorable resolutions could occur. As of March 31, 2024, there was no material litigation against the Company.

Stock Incentive Plans

2021 Plan

In March 2021, the Company adopted the iSpecimen Inc. 2021 Stock Incentive Plan, which was subsequently amended in June 2021 and then on May 25, 2022 (the “2021 Plan”). The 2021 Plan was adopted to enhance the Company’s ability to attract, retain and motivate employees, officers, directors, consultants, and advisors by providing such persons with equity ownership opportunities and performance-based incentives. The 2021 Plan authorizes options, restricted stock, RSUs and other stock-based awards. The Company's board of directors, or any committee to which the board of directors delegates such authority, has the sole discretion in administering, interpreting, amending, or accelerating the 2021 Plan. Awards may be made under the 2021 Plan for up to 608,000 shares of the Company's common stock, and the 2021 Plan was made effective with the completion of the IPO.

On May 24, 2023, at the Company’s annual meeting of stockholders, the stockholders approved an amendment to the 2021 Plan to increase the number of shares under the 2021 Plan from 608,000 shares of common stock to 1,869,500 shares of common stock.

During the three months ended March 31, 2024 and 2023, 80,340 and 118,247 equity awards were granted under the 2021 Plan, respectively. As of March 31, 2024, there were 1,320,028 shares of common stock available for future grants under the 2021 Plan.

2013 Plan

The iSpecimen Inc. 2013 Stock Incentive Plan (the “2013 Plan”) was adopted on April 12, 2013 and subsequently amended on July 29, 2015. The aggregate number of shares of common stock that may be issued pursuant to the 2013 Plan was 1,713,570.

No equity awards were granted under the 2013 Plan during the three months ended March 31, 2024 and 2023. According to the 2013 Plan, which was adopted by the Company’s board of directors on April 12, 2013, no awards shall be granted under the 2013 Plan after

the completion of ten years from the date on which the 2013 Plan was adopted by the Company’s board of directors. Therefore, as of April 13, 2023, no further shares had been granted under the 2013 Plan.

Stock Options

During the three months ended March 31, 2024 and 2023, the Company granted 80,340 and 117,500 stock options, respectively.

As of March 31, 2024 and December 31, 2023, the Company had federal net operating loss carryforwards of approximately $53,200,000 and $50,800,000, respectively, of which approximately $13,000,000 expires at various periods through 2037 and approximately $40,200,000 and $37,800,000, respectively, can be carried forward indefinitely. As of March 31, 2024 and December 31, 2023, the Company had state net operating loss carryforwards of approximately $32,300,000 and $31,100,000, respectively, that expire at various periods through 2043, respectively. As of March 31, 2024 and December 31, 2023, the Company had federal and state tax credits of approximately $2,110,700 and $2,058,300, respectively, available for future periods that expire at various periods through 2043. The Company has recorded a full valuation allowance against net deferred income tax assets due to a history of losses generated since inception.

Due to changes in ownership provisions of the Internal Revenue Code of 1986 (the “IRC”), the availability of the Company's net operating loss carryforwards may be subject to annual limitations under Section 382 of the IRC against taxable income in the future period, which could substantially limit the eventual utilization of such carryforwards.

Mar. 31, 2024

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

Use of Estimates

The preparation of the Company’s unaudited condensed financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Company utilizes certain estimates in the determination of the deferred tax valuation allowances, revenue recognition, stock-based compensation, allowance for doubtful accounts, accrued expenses, and the useful lives of internally developed software and sequenced data. The Company bases its estimates on historical experience and other market-specific or other relevant assumptions that it believes to be reasonable under the circumstances. Actual results could differ from such estimates.

Investments

Investments

The Company’s investments are considered to be available-for-sale as defined under ASC 320, Investments – Debt Securities, and are recorded at fair value. Unrealized gains and losses are included in accumulated other comprehensive income. Purchases and sales of securities are reflected on a trade-date basis. Realized gains or losses are released from accumulated other comprehensive income and into earnings on the statement of operations, and amortization of premiums and accretion of discounts on the U.S treasury bills are recorded in interest expense or income, respectively.

The Company continually monitors the difference between its cost basis and the estimated fair value of its investments. The Company’s accounting policy for impairment recognition requires other-than-temporary impairment charges to be recorded when it determines that it is more likely than not that it will be unable to collect all amounts due according to the contractual terms of the fixed maturity security or that the anticipated recovery in fair value of the equity security will not occur in a reasonable amount of time. Impairment charges on investments are recorded based on the fair value of the investments at the measurement date or based on the value calculated using a discounted cash flow model. Credit-related impairments on fixed maturity securities that the Company does not plan to sell, and for which it is not more likely than not to be required to sell, are recognized in net income. Any non-credit related impairment is recognized as a component of other comprehensive income. Factors considered in evaluating whether there is a decline in value include: the length of time and the extent to which the fair value has been less than cost; the financial condition and near-term prospects of the issuer; and the likelihood that it will be required to sell the investment.

Fair Value Measurements

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability of fair value measures, the following hierarchy prioritizes the inputs to valuation methodologies used to measure fair value:

● Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets.

● Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

● Level 3 — Valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.

For certain financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable, the carrying amounts approximate their fair values as of March 31, 2024 and December 31, 2023, respectively, because of their short-term nature. Available-for-sale securities are recorded at fair value and as level 1 investments.

Revenue Recognition and Accounts Receivable

Revenue Recognition and Accounts Receivable

The Company recognizes revenue using the five-step approach as follows: (1) identify the contract with the customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when (or as) the Company satisfies the performance obligations.

The Company generates revenue by procuring various specimens from hospitals, laboratories, and other supply sites, for the Company’s medical research customers using the Company’s proprietary software, the iSpecimen Marketplace, to identify, locate, and ultimately validate the required specimens to the Company’s customers’ requested specifications. The Company’s performance obligation is to procure a specimen meeting the customer’s specification(s) from a supplier, on a “best efforts” basis, for the Company’s customer at the agreed price per specimen as indicated in the customer’s contract with the Company. The Company does not currently charge suppliers or customers for the use of the Company’s proprietary software. Each customer will execute a material and data use agreement with the Company or agree to online purchase terms, each of which includes terms such as specimen and data use, shipment terms, payment, and cancellation terms. These are then supplemented by purchase orders that specify specimen requirements including detailed inclusion/exclusion criteria, quantities to be collected, and pricing. Collectively, these customer agreements represent the Company’s contracts with its customer. Generally, contracts have fixed unit pricing. For certain specimen orders, a refundable customer deposit may be required prior to order fulfillment depending on project set-up requirements, which is presented as deferred revenue. The Company expects to recognize the deferred revenue within the next twelve months.

Specimen collections occur at supply sites within the Company’s network. “Collection” is when the specimen has been removed, or “collected” from the patient or donor. A specimen is often collected specifically for a particular Company order. Once collected, the specimen is assigned by the supplier to the Company and control of the specimen passes to the Company. “Accession” is the process whereby a collected specimen and associated data are registered and assigned in the iSpecimen Marketplace to a particular customer order, which can occur while a specimen is at the supplier site or while at the Company site and it is when control of the specimen passes to the customer. Suppliers may ship specimens to the Company or directly to the customer if specimens must be delivered within a short time period (less than 24 hours after collection) or shipping to the Company is not practical.

The Company has evaluated principal versus agent considerations as part of the Company’s revenue recognition policy. The Company has concluded that it acts as principal in the arrangement as it manages the procurement process from beginning to end and determines which suppliers will be used to fulfill an order, usually takes physical possession of the specimens, sets prices for the specimens, and bears the responsibility for customer credit risk.

The Company recognizes revenue over time, as the Company has created an asset with no alternative use to the Company, which has an enforceable right to payment for performance completed to date. At contract inception, the Company reviews a contract and related order upon receipt to determine if the specimen ordered has an alternative use by the Company. Generally, specimens ordered do not have an alternative future use to the Company and the performance obligation is satisfied when the related specimens are accessioned. The Company uses an output method to recognize revenue for specimens with no alternative future use. The output is measured based on the number of specimens accessioned. In the rare circumstances where specimens do have an alternative future use, the Company's performance obligation is satisfied at the time of shipment.

Customers are generally invoiced upon shipment. Depending on the quantity of specimens ordered, it may take several accounting periods to completely fulfill a purchase order. In other words, there can be multiple invoices issued for a single purchase order, reflecting the specimens being accessioned over time. However, specimens are generally shipped as soon as possible after they have been accessioned.

Once a specimen that has no alternative future use and for which the Company has an enforceable right to payment has been accessioned, the Company records the offset to revenue in accounts receivable – unbilled. Once the specimen has been shipped and invoiced, a reclassification is made from accounts receivable - unbilled to accounts receivable.

Customers are generally given fourteen days from the receipt of specimens to inspect the specimens to ensure compliance with specifications set forth in the purchase order documentation. Customers are entitled to either receive replacement specimens or receive reimbursement of payments made for such specimens. The Company has a nominal history of returns for nonacceptance of specimens delivered. When this occurs, the Company gives the customer a credit for the returns. The Company has not recorded a returns allowance.

The following table summarizes the Company’s revenue for the three months ended March 31:

	2024		2023
Specimens - contracts with customers	$	2,136,100	$	2,712,376
Shipping and other		153,893		237,821
Revenue	$	2,289,993	$	2,950,197

The Company carries its accounts receivable at the invoiced amount less an allowance for doubtful accounts. On a periodic basis, the Company evaluates its accounts receivable to determine if an allowance for doubtful accounts is necessary, based on economic conditions and each customer’s payment history. Receivables are written off when deemed uncollectible, with any future recoveries recorded as income when received. As of March 31, 2024 and December 31, 2023, the Company had an allowance for doubtful accounts of $718,821 and $520,897, respectively.

The Company applies the practical expedient to account for shipping and handling activities as fulfillment cost rather than as a separate performance obligation. Shipping and handling costs incurred are included in cost of revenue.

Internally Developed Software, net

Internally Developed Software, Net

The Company capitalizes certain internal and external costs incurred during the application development stage of internal-use software projects until the software is ready for its intended use. Amortization of the asset commences when the software is complete and placed into service and is recorded in operating expenses. The Company amortizes completed internal-use software over its estimated useful life of five years on a straight-line basis. Costs incurred during the planning, training and post-implementation stages of the software development life cycle are classified as technology costs and are expensed to operations as incurred.

Other Intangible Assets, Net

Other Intangible Assets, Net

The Company procures data generated from sequencing of Formalin-Fixed Paraffin-Embedded (“FFPE”) blocks from a third-party sequencer which the Company licenses to its customers with the sale of FFPE blocks at an additional cost. The sequenced data is also organized to form a database of research content that is available for sale through a subscription model. The Company has determined that the sequenced data is an intangible asset and capitalizes the cost to procure the sequenced data. The sequenced data is amortized to

cost of revenue over an estimated useful life of five years on a straight-line basis. The costs paid to the third-party sequencer are the only costs capitalized and all other related costs are expensed to operations as incurred.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets

Management reviews long-lived assets for impairment when circumstances indicate the carrying amount of an asset may not be recoverable. An impairment loss is recognized when expected cash flows are less than the asset’s carrying value. Long-lived assets consist of property and equipment, internal-use software and other intangible assets. No impairment charges were recorded for the three months ended March 31, 2024 and 2023.

Stock-Based Compensation

Stock-Based Compensation

The Company records stock-based compensation for options granted to employees, non-employees, and to members of the board of directors for their services to the Company based on the grant date fair value of awards issued, and the expense is recorded on a straight-line basis over the requisite service period. Forfeitures are recognized when they occur.

The Company uses the Black-Scholes-Merton option pricing model to determine the fair value of stock options. The use of the Black-Scholes-Merton option pricing model requires management to make assumptions with respect to the expected term of the option, the expected volatility of the common stock consistent with the expected life of the option, risk-free interest rates and expected dividend yields of the common stock. The Company has concluded that its historical share option exercise experience does not provide a reasonable basis upon which to estimate expected term. Therefore, the expected term was determined according to the simplified method, which is the average of the vesting tranche dates and the contractual term. Due to the lack of Company-specific historical and implied volatility data, the estimate of expected volatility is primarily based on the historical volatility of a group of similar companies that are publicly traded. For these analyses, companies with comparable characteristics are selected, including enterprise value and position within the industry, and with historical share price information sufficient to meet the expected life of the stock-based awards. The Company computes the historical volatility data using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term of its stock-based awards.

The risk-free interest rate is determined by reference to U.S. Treasury zero-coupon issues with remaining maturities similar to the expected term of the options. The Company has not paid, and does not anticipate paying, cash dividends on shares of its common stock.

The fair value of the Company’s common stock is equal to the closing price on the specified grant date.

Restricted Stock Units (“RSUs”)

The Company recognizes stock-based compensation expense from RSUs ratably over the specified vesting period. The fair value of RSUs is determined to be the closing share price of the Company’s common stock on the grant date.

Common Stock Warrants

Common Stock Warrants

The Company accounts for common stock warrants as either equity instruments or liabilities, depending on the specific terms of the warrant agreement. The warrants shall be classified as a liability if 1) the underlying shares are classified as liabilities or 2) the entity can be required under any circumstances to settle the warrant by transferring cash or other assets. The measurement of equity-classified non-employee stock-based payments is generally fixed on the grant date and are considered compensatory. For additional discussion on warrants, see Note 9.

Net Loss Per Share

Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss applicable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by adjusting the weighted-average number of shares outstanding for the dilutive effect of common stock equivalents

outstanding for the period, determined using the treasury-stock method. Therefore, basic and diluted net loss per share applicable to common stockholders were the same for all periods presented.

The table below provides information on shares of the Company’s common stock issuable upon vesting and exercise, as of March 31:

	2024	2023
Shares issuable upon vesting of RSUs	96,788	216,058
Shares issuable upon exercise of stock options	350,062	330,788
Shares issuable upon exercise of PIPE Warrant (defined below) to purchase common stock	—	1,312,500
Shares issuable upon exercise of Lender Warrant (defined below) to purchase common stock	12,500	12,500
Shares issuable upon exercise of Underwriter Warrant (defined below) to purchase common stock	90,000	90,000

Recently Adopted Accounting Standards

Recently Adopted Accounting Standards

In June 2016, the FASB issued Accounting Standards Updates (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the impairment model for most financial assets and certain other instruments. For receivables, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowance for losses. In addition, an entity will have to disclose significantly more information about allowances and credit quality indicators. The new standard is effective for the Company for fiscal years beginning after December 15, 2022. The Company adopted this new standard as of January 1, 2023. ASU 2016-13 did not have a material impact on the Company’s unaudited condensed financial statements.

In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies an issuer’s accounting for convertible instruments by reducing the number of accounting models that require separate accounting for embedded conversion features. ASU 2020-06 also simplifies the settlement assessment that entities are required to perform to determine whether a contract qualifies for equity classification and makes targeted improvements to the disclosures for convertible instruments and earnings-per-share (EPS) guidance. This update will be effective for the Company’s fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Entities can elect to adopt the new guidance through either a modified retrospective method of transition or a fully retrospective method of transition. The Company adopted this new standard as of January 1, 2024. ASU 2020-06 did not have a material impact on the Company’s unaudited condensed financial statements.
