Note 2. Summary of Significant Accounting Policies

Basis of Presentation and Liquidity

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

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation.

On November 8, 2023, the Company completed the sale of substantially all of the assets relating to its Orthobiologics segment (the “Orthobiologics Business”) to Berkeley Biologics, LLC (“Berkeley”). The Orthobiologics Business was comprised of assets relating to researching, developing, administering, insuring, operating, commercializing, manufacturing, selling and marketing the Company’s Orthobiologics products, and the business of contract manufacturing of particulate bone, precision milled bone, cellular bone matrix, acellular dermis, soft tissue and other products. The assets sold represent the entirety of the Company’s Orthobiologics segment. In the sale, the Company received approximately $14.6 million, and the Company may earn up to an additional $20 million, in the aggregate, in the form of earn-out payments. The earn-out payments are equal to 10% of the actual revenue earned by Berkeley in each of the five years after the closing of the sale from sales of specified Orthobiologics products under the purchase agreement (including improvements, modifications, derivatives and enhancements related to those products). Additionally, the purchase agreement provides for a customary indemnity holdback in the amount of $1.5 million to be retained by Berkeley for 24 months after close. The Company recognized a gain of approximately $6.0 million on the sale of the Orthobiologics Business which is recorded in "Income from discontinued operations" in the Company's consolidated statement of operations for the year ended December 31, 2023. Should the Company receive incremental proceeds in the future through an Earn-Out Payment or payment of the holdback amount, an additional gain will be recorded upon the receipt of such amounts.

The sale of the Orthobiologics Business represents a strategic shift that has a major effect on the Company’s operations and financial results. Accordingly, this transaction is accounted for as Discontinued Operations for all periods presented in accordance with Accounting Standards Codification (“ASC”) 205-20, Discontinued Operations. Unless indicated otherwise, the information in the notes to the consolidated financial statements relates to continuing operations. See Note 4 for further discussion of the divestiture of the Orthobiologics Business.

In accordance with Accounting Standards Update (“ASU”) 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40), the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the consolidated financial statements are issued. For the year ended December 31, 2023, the Company incurred a net loss of $37.7 million, and as of December 31, 2023, the Company had an accumulated deficit of $175.6 million. In addition, during the year ended December 31, 2023, the Company used $21.8 million of cash in operating activities and expects to continue to incur cash outflows in 2024. Because of the numerous risks and uncertainties associated with the Company’s commercialization and development efforts, the Company is unable

to predict when it will become profitable, and it may never become profitable. The Company’s inability to achieve and then maintain profitability would negatively affect its business, financial condition, results of operations and cash flows. Furthermore, even if the Company does achieve profitability, it may not be able to sustain or increase profitability on an ongoing basis, or, in general, be able to satisfy its obligations, including those related to the FiberCel Recall described in Note 17, when they become due.

In order to mitigate the current and potential future liquidity issues caused by the matters noted above, the Company may seek to raise capital through the issuance of common stock, such as the private placement which we closed in September 2023, which is described further in Note 14, or pursue asset sale or other transactions, such as the sale of the Orthobiologics Business described above. However, such transactions may not be successful and the Company may not be able to raise additional equity or sell or license assets on acceptable terms, or at all. As such, based on its current operating plans, the Company believes there is uncertainty as to whether its future cash flows along with its existing cash, issuances of additional equity and cash generated from expected future sales will be sufficient to meet the Company’s anticipated operating needs through twelve months from the financial statement issuance date. Due to these factors, there is substantial doubt about the Company’s ability to continue as a going concern within one year after the issuance of the financial statements.

The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. That is, the accompanying financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates continuity of operations, realization of assets, and satisfaction of liabilities in the ordinary course of business.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates and assumptions relating to inventories, receivables, long-lived assets, the valuation of stock-based awards, the valuation of the revenue interest obligation, the valuation of the warrant liability, the contingent liability for the FiberCel Litigation and deferred income taxes are made at the end of each financial reporting period by management. Management continually re-evaluates its estimates, judgments and assumptions, and management's evaluation could change. Actual results could differ from those estimates.

Net Loss per Share Attributable to Common Stockholders

Our common stock has a dual class structure, consisting of Class A common stock, $0.001 par value per share (the “Class A common stock) and Class B common stock, $0.001 par value per share (the “Class B common stock). Other than voting rights, the Class B common stock has the same rights as the Class A common stock, and therefore both are treated as the same class of stock for purposes of the earnings per share calculation. Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average shares outstanding during the period. For purposes of the diluted net income (loss) per share attributable to common stockholders calculation, stock options, restricted stock units (“RSUs”) and certain warrants are considered to be common stock equivalents. All common stock equivalents have been excluded from the calculation of diluted net loss per share attributable to common stockholders, as their effect would be anti-dilutive for all periods presented. Therefore, basic and diluted net loss per share were the same for both periods presented.

Fair Value of Financial Instruments

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.

The estimated fair value of financial instruments disclosed in the financial statements has been determined by using available market information and appropriate valuation methodologies. The carrying value of all current assets and current liabilities approximates fair value because of their short-term nature.

Cash and Cash Equivalents

The Company maintains its cash balances at banks and financial institutions. The balances are insured up to the legal limit. The Company maintains cash balances that may, at times, exceed this insured limit. The Company considers cash on hand, demand deposits in a bank, money market funds, and all highly liquid investments with an original maturity of 90 days or less to be cash and cash equivalents.

Accounts Receivable and Allowances

Accounts receivable in the accompanying balance sheets are presented net of allowances for doubtful accounts and other credits. The Company grants credit to customers in the normal course of business, but generally does not require collateral or any other security to support its receivables.

The Company evaluates the collectability of accounts receivable based on a combination of factors. In circumstances where a specific customer is unable to meet its financial obligations to the Company, a provision to the allowance for doubtful accounts is recorded to reduce the net recognized receivable to the amount that is reasonably expected to be collected. For all other customers, a provision to the allowance for doubtful accounts is recorded based on factors including the length of time the receivables are past due, the current business environment and the Company’s historical experience. Provisions to the allowance for doubtful accounts are recorded to general and administrative expenses. Account balances are charged off against the allowance when it is probable that the receivable will not be recovered. The Company's allowance for doubtful accounts was approximately $0.7 million and $0.1 million as of December 31, 2023 and 2022, respectively.

Inventories

Inventories, consisting of purchased materials, direct labor and manufacturing overhead, are stated at the lower of cost or net realizable value, with cost determined generally using the average cost method. At each balance sheet date, the Company also evaluates inventories for excess quantities, obsolescence or shelf life expiration. This evaluation includes analysis of the Company’s current and future strategic plans, historical sales levels by product, projections of future demand, the risk of technological or competitive obsolescence for products, general market conditions and a review of the shelf life expiration dates for products. To the extent that management determines there is excess or obsolete inventory or quantities with a shelf life that is too near its expiration for the Company to reasonably expect that it can sell those products prior to their expiration, the Company adjusts the carrying value to estimated net realizable value.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line method over the following estimated useful lives of the assets:


Processing and research equipment		5 to 10 years
Office equipment and furniture		3 to 5 years
Computer hardware and software		3 years

Leasehold improvements are amortized on the straight-line method over the shorter of the lease term or the estimated useful life of the asset. Repairs and maintenance costs are expensed as incurred.

Leases

In February 2016, the FASB issued ASU No 2016-02 “Leases” to increase the transparency and comparability about leases among entities. Additional ASUs have been issued subsequent to ASU 2016-02 to provide supplementary clarification and implementation guidance for leases related to, among other things, the application of certain practical expedients, the rate implicit in the lease, lessee reassessment of lease classification, lessor reassessment of lease term and purchase options, variable payments that depend on an index or rate and certain transition adjustments. ASU 2016-02 and these additional ASUs are now codified as Accounting Standards Codification Standard 842 - “Leases” (“ASC 842”). ASC 842 supersedes the lease accounting guidance in Accounting Standards Codification 840 “Leases” (“ASC 840”) and requires lessees to recognize a lease liability and a corresponding lease asset for virtually all lease contracts. It also requires additional disclosures about leasing arrangements. The Company elected to utilize the “package” of expedients, as defined in ASC 842, which retain the lease classification and initial direct costs for any leases that existed prior to adoption of the standard. Accordingly, previously reported financial information has not been restated to reflect the application of the new standard to the comparative periods presented. The Company adopted the standard in the fourth quarter of 2022 for the full 2022 year resulting in the recognition of a Right-of-use (“ROU”) asset and operating lease liability on the Company’s consolidated balance sheet of approximately $2.4 million as of January 1, 2022. As the ROU asset and the lease payable obligation were essentially the same upon adoption of ASC 842, there was no cumulative effect impact on the Company’s accumulated deficit.

The Company determines if an arrangement contains a lease at inception. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from that lease. For leases with a term greater than 12 months, ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The lease term includes the option to extend the lease when it is reasonably certain the Company will exercise that option. When available, the Company uses the rate implicit in the lease to discount lease payments to present value. In the case the implicit rate is not available, the Company uses its incremental borrowing rate based on information available at the lease commencement date, including publicly available data for instruments with similar characteristics, to determine the present value of lease payments. The Company combines lease and non-lease elements for office leases.

Long-Lived Assets

Purchased intangible assets with finite lives are carried at acquired fair value, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets.

The Company periodically evaluates the period of depreciation or amortization for long-lived assets to determine whether current circumstances warrant revised estimates of useful lives. The Company reviews its property and equipment and intangible assets for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. Impairment exists when the carrying value of the company’s asset exceeds the related estimated undiscounted future cash flows expected to be derived from the asset. If impairment exists, the carrying value of that asset is adjusted to its fair value. A discounted cash flow analysis is used to estimate an asset’s fair value, using assumptions that market participants would apply. The results of impairment tests are subject to management’s estimates and assumptions of projected cash flows and operating results. Changes in assumptions or market conditions could result in a change in estimated future cash flows and could result in a lower fair value and therefore an impairment, which could impact reported results. There were no impairment losses for the years ended December 31, 2023 and 2022.

Warrant Liability

The Company accounts for its warrants in accordance with ASC 815, Derivatives and Hedging – Contracts in Entity's Own Equity, as either liabilities or as equity instruments depending on the specific terms of the warrant agreement. The Prefunded and Common Warrants issued in connection with the September 2023 private placement (see Note 14) are

classified as liabilities and are recorded at fair value. The warrants are subject to re-measurement at each settlement date and at each balance sheet date and any change in fair value is recognized in other expense (income), net in the consolidated statements of operations. The Company estimates the fair value of the warrant liability using a Black-Scholes pricing model. We are required to make assumptions and estimates in determining an appropriate term, risk-free interest rate, volatility factor, dividend yield, and the fair value of common stock. Any significant adjustments to the unobservable inputs would have a direct impact on the fair value of the warrant liability.

Revenue Recognition

The Company’s revenue is generated from contracts with customers in accordance with ASC 606. The core principle of ASC 606 is that the Company recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. The ASC 606 revenue recognition model consists of the following five steps: (1) identify the contracts with a 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 entity satisfies a performance obligation.

As noted above, the Company enters into contracts to primarily sell and distribute products to healthcare providers or commercial partners. Revenue is recognized when the Company has met its performance obligations pursuant to its contracts with its customers in an amount that the Company expects to be entitled to in exchange for the transfer of control of the products to the Company’s customers. For all product sales, the Company has no further performance obligations and revenue is recognized at the point control transfers which occurs either when: i) the product is shipped via common carrier; or ii) the product is delivered to the customer or distributor, in accordance with the terms of the agreement.

A portion of the Company’s product revenue is generated from consigned inventory maintained at hospitals and from inventory physically held by distributors and direct sales representatives. For these types of products sales, the Company retains control until the product has been shipped, used or implanted, at which time revenue is recognized.

The Company elected to account for shipping and handling activities as a fulfillment cost rather than a separate performance obligation. Amounts billed to customers for shipping and handling are included as part of the transaction price and recognized as revenue when control of the underlying products is transferred to the customer. The related shipping and freight charges incurred by the Company are included in sales and marketing costs. Shipping and handling costs were not material in both the years ended December 31, 2023 and 2022, respectively.

Contracts with customers state the final terms of the sale, including the description, quantity, and price of each implant distributed. The payment terms and conditions in the Company’s contracts vary; however, as a common business practice, payment terms are typically due in full within 30 to 60 days of delivery. The Company, at times, extends volume discounts to customers.

The Company permits returns of its products in accordance with the terms of contractual agreements with customers. Allowances for returns are provided based upon analysis of the Company’s historical patterns of returns matched against the revenues from which they originated. The Company records estimated returns as a reduction of revenue in the same period revenue is recognized.

Stock-Based Compensation Plans

The Company accounts for its stock-based compensation plans in accordance with FASB Accounting Standards Codification (“ASC”) 718, Accounting for Stock Compensation. FASB ASC 718 requires the measurement and recognition of compensation expense for all stock-based awards made to employees and directors, including employee stock options and restricted stock units. Stock-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense on a straight-line basis over the requisite service period of the entire award.

Research and Development Costs

Research and development costs, which include mainly salaries, outside services and supplies, are expensed as incurred.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash. The Company’s cash balances with the individual institutions may at times exceed the federally insured limits.

As of December 31, 2023, there was one customer that represented 10% of the Company’s net sales for the year ended 2023 and another customer that represented 31% of the Company’s accounts receivable as of December 31, 2023.

Comprehensive Income (Loss)

Comprehensive income (loss) comprises net income (loss) and other changes in equity that are excluded from net income (loss). For the years ended December 31, 2023 and 2022, the Company’s net loss equaled its comprehensive loss and accordingly, no additional disclosure is presented.

Income Taxes

The Company uses the asset and liability method of accounting for income taxes. Deferred income taxes are recorded to reflect the tax consequences on future years for differences between the tax basis of assets and liabilities and their financial reporting amounts at each year-end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to amounts that are more likely than not to be realized.

The Company is subject to income taxes in the federal and state jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. In accordance with the authoritative guidance on accounting for uncertainty in income taxes, the Company recognizes tax liabilities for uncertain tax positions when it is more likely than not that a tax position will not be sustained upon examination and settlement with various taxing authorities. Liabilities for uncertain tax positions are measured based upon the largest amount of benefit that is more likely than not (greater than 50%) of being realized upon settlement. The Company’s policy is to recognize interest and/or penalties related to income tax matters in income tax expense.

Note 10. Long-Term Debt

On May 31, 2017, the Company entered into a $12 million term loan facility (“MidCap Loan Facility”) and an $8.0 million asset-backed revolving line of credit (“MidCap Credit Facility”), under which the Company’s borrowing capacity was limited by certain qualifying assets, with MidCap Financial Trust (“May 2017 Financing”). The MidCap Loan Facility was amended in December 2017, February 2018 and July 2019 (all amendments being considered modifications) such that an additional $1.5 million, $3.0 million, and $3.5 million, respectively were received by the Company bringing the total aggregate principal amount outstanding under the MidCap Loan Facility to $20 million. The borrowings under the MidCap Loan Facility and the MidCap Credit Facility were fully repaid with a portion of the proceeds from the SWK Loan Facility as more fully described below.

On August 10, 2022, the Company entered into a senior secured term loan facility with SWK Funding LLC, as agent, and other lenders party thereto for an aggregate principal amount of $25 million, and the Company amended the facility on May 12, 2023 (as amended, the “SWK Loan Facility”). An initial draw of $21 million was made in August 2022, with the additional $4 million drawn on December 14, 2022 upon satisfaction of the amended terms enabling such receipt. The SWK Loan Facility also allows for the establishment of a separate, new asset-based revolving loan facility of up to $8 million, which has not been entered into to date. The SWK Loan Facility matures on August 10, 2027 and accrues interest, payable quarterly in arrears. Principal amortization of the SWK Loan Facility starts on November 15, 2024, which amortization may be extended to November 17, 2025 if certain conditions have been satisfied. Principal payments during the amortization period will be limited based on revenue-based caps. As of December 31, 2023, quarterly principal payments are scheduled to begin on November 15, 2024, in an amount equal to 5% of the aggregate principal amount funded with the balance paid at maturity. The SWK Loan Facility also includes both revenue and liquidity covenants, restrictions as to payment of dividends, and is secured by all assets of the Company, subject to certain customary exceptions. As of December 31, 2023, Elutia was in compliance with its financial covenants under the agreement governing the SWK Loan Facility (“SWK Loan Facility Agreement”).

All of the SWK Loan Facility borrowings take the form of Secured Overnight Financing Rate (“SOFR”) loans and bear interest at a rate per annum equal to the sum of an applicable margin of (i) 7.75% and the “Term SOFR Rate” (based upon an interest period of 3 months), or (ii) if the Company has elected the PIK Interest option (as defined below), 3.75% and the “Term SOFR Rate.” The Company may elect a portion of the interest due, to be paid in-kind at a rate per annum of 4.5% (“PIK Interest”), and such election may be made (x) until November 15, 2024 if the conditions to draw the Additional Term Loan have not been met, or (y) if such conditions to draw the Additional Term Loan have been satisfied, until November 17, 2025. The “Term SOFR Rate” is subject to a floor of 2.75%. The agreement governing the SWK Loan Facility also includes an exit fee equal to 6.5% of the aggregate principal amount funded prior to termination plus $62,500 and prepayment penalties equal to: (i) if such prepayment occurs prior to the first anniversary of the Closing Date, 2% of the aggregate principal amount funded prior to the termination plus remaining unpaid interest payments scheduled to be paid during the first year of the loan or (ii) if such prepayment occurs after the first anniversary of the Closing Date but prior to the second anniversary of the Closing Date, 2% of the aggregate principal amount funded prior to the termination. The weighted average interest rate on the SWK Loan Facility was 13.2% for the year ended December 31, 2023 and 12.6% for the period from August 10, 2022 through December 31, 2022.

On August 10, 2022, the Company issued to SWK Funding LLC a warrant (“Class A Warrant”) to purchase, in the aggregate, up to 187,969 shares of Class A common stock of the Company, $0.001 par value per share at an exercise price of $6.65 per share. The Class A Warrant is immediately exercisable for up to 187,969 shares of Class A common stock from time to time on or after the Closing Date. The exercise price and number of shares of Class A common stock issuable upon exercise of the Class A Warrant are subject to adjustment in the event of stock dividends, stock splits and certain other events affecting the Class A common stock. Unless earlier exercised or terminated in accordance with its terms, the Class A Warrant will expire on the seventh anniversary of the Closing Date. Upon issuance, the Company valued the Class A Warrant at approximately $0.6 million using the Black-Scholes model. The recognition of the Class A Warrant as well as deferred financing costs of approximately $0.5 million incurred in securing the SWK Loan Facility

served to reduce the recorded value of the associated debt. The debt discount and deferred financing costs will be recognized as interest expense through the maturity of the loan.

The Company used $16 million of the proceeds of the SWK Loan Facility to repay all outstanding obligations on the MidCap Loan Facility and MidCap Credit Facility. Such payment included (i) $12.8 million to repay all outstanding principal and accrued interest on the MidCap Loan Facility, (ii) $1.7 million to pay the prepayment and exit fees on the MidCap Loan Facility and (iii) $1.5 million to repay the outstanding balance, accrued interest and exit fees on the MidCap Credit Facility. The prepayment fees, payment of unaccrued exit fees and the write-off of unamortized deferred financing costs resulted in a loss to the Company of approximately $1.2 million which has been recorded as other expense (income), net in the accompanying consolidated statements of operations for the year ended December 31, 2022.

The SWK Loan Facility Agreement requires certain mandatory prepayments, subject to certain exceptions, with: (1) 100% of any net casualty proceeds in excess of $250,000 and (2) for non-ordinary course asset sales, an amount equal to the difference between (x) the proportion of divested gross profit (as defined in the SWK Loan Facility Agreement) to the Company’s total gross profit (as defined in the SWK Loan Facility Agreement) multiplied by the outstanding loans under the SWK Loan Facility and (y) the difference between $1,000,000 and the aggregate sale proceeds of any assets previously sold during the fiscal year. No such mandatory prepayments were required during the year ended December 31, 2022; however, the closing of the divestiture of the Orthobiologics Business on November 8, 2023 triggered the mandatory prepayment of $4.0 million. Of such amount, $2.0 million was paid shortly after closing of the divestiture of the Orthobiologics Business and the remainder was paid on February 15, 2024 based on mutual agreement between the parties.

Borrowings under the MidCap Loan Facility, as amended, bore interest at a rate per annum equal to the sum of (x) the greater of (i) 2.25% and (ii) the applicable London Interbank Offered Rate for U.S. dollar deposits divided by 1.00 minus the maximum effective reserve percentage for Eurocurrency funding (“LIBOR”) plus (y) 7.25%. The weighted average interest rate on MidCap Loan Facility was 9.5% from January 1, 2022 through August 10, 2022 (the “Repayment Date”). Borrowings under the MidCap Credit Facility bore interest at a rate per annum equal to the sum of (x) the greater of (i) 2.25% and (ii) LIBOR plus (y) 4.95%. The weighted average interest rate on MidCap Credit Facility was 7.2% from January 1, 2022 through the Repayment Date.

During 2017, the Company restructured certain of its liabilities with a tissue supplier and entered into an unsecured promissory note totaling $2.1 million. The note bears interest at 5% and includes quarterly interest-only payments in 2017 and quarterly interest and principal payments from March 31, 2018 through August 31, 2021. The Company used $1.4 million of the proceeds from the SWK Loan Facility to repay the remaining balance on the promissory note; however the accrued interest on the promissory note was forgiven by the lender. Such forgiveness resulted in a gain to the Company of approximately $0.4 million which has been recorded as other expense (income), net in the accompanying consolidated statements of operations for the year ended December 31, 2022.

As of December 31, 2023, the contractual maturities of the long-term debt are as follows (in thousands):



Years ending December 31,	Term Loan
2024	$	3,321
2025		5,282
2026		5,282
2027		10,571
Total		24,456
Debt Discount		(440)
Deferred Financing Costs		(339)
Total, net		23,677
Current Portion		(3,321)
Long-term Debt	$	20,356

In addition to the above, the Company finances the annual premiums of certain insurance policies through short-term financing arrangements and includes the liabilities associated with such arrangements within accrued liabilities in accompanying consolidated balance sheets. The fair value of all debt instruments, which is based on inputs considered to be Level 2 under the fair value hierarchy, approximates the respective carrying values as of December 31, 2023 and 2022.

Revenue Interest Obligation

Revenue Interest Obligation

Note 11. Revenue Interest Obligation

As part of the CorMatrix asset acquisition described in Note 9, the Company assumed a restructured, long-term obligation (the “Initial Revenue Interest Obligation”) to Ligand Pharmaceuticals (“Ligand”) with an estimated present value on the acquisition date of $27.7 million. Subject to annual minimum payments of $2.75 million per year, the terms of the Initial Revenue Interest Obligation require Elutia to pay Ligand, 5% of future sales of the products Elutia acquired from CorMatrix, including CanGaroo, ProxiCor, Tyke and VasCure, as well as products substantially similar to those products, such as the version of CanGaroo that Elutia is currently developing that is designed to include antibiotics. Furthermore, a $5.0 million payment will be due to Ligand if cumulative sales of these products exceed $100 million and a second $5.0 million will be due if cumulative sales exceed $300 million during the ten-year term of the agreement which expires on May 31, 2027.

On January 10, 2024, the Company entered into an amendment to the Revenue Interest Obligation (“Amended Revenue Interest Obligation”). Pursuant to the Amended Revenue Interest Obligation, the parties modified and restructured the Revenue Interest Obligation by (i) revising the annual minimum payments for 2024 and each subsequent fiscal year during the term of the agreement from $2.75 million to $4.4 million; (ii) agreeing to a payment by the Company of $3.0 million in satisfaction of all royalty obligations for the first three fiscal quarters of 2023, with half of such amount to be paid not later than January 20, 2024, and the remainder to be paid not later than April 10, 2024; (iii) agreeing to a payment by the Company of $1.1 million in satisfaction of the royalty obligations for the fourth quarter of 2023; and (iii) waiving the obligation of Elutia to make the $5.0 million milestone payment that became due to Ligand in the second quarter of 2023.

As of December 31, 2023, the Company recorded the present value of the estimated total future payments under the Initial Revenue Interest Obligation as a long-term obligation and the short-term portion is comprised of (i) the 2023 and 2024 minimum payments, (ii) the first $5.0 million sales milestone payment noted above and (iii) the unpaid portion of the 2022 minimum payments. The short-term portion as of December 31, 2022 is comprised of (i) the 2023 minimum payments, (ii) the first $5.0 million sales milestone payment noted above and (iii) the unpaid portion of the 2022 minimum payments.

Common Stock and Warrants

Note 14. Common Stock and Warrants

Private Placement of Common Stock and Warrants

On September 21, 2023, the Company sold, in a private offering an aggregate of (i) 6,852,811 units (“Common Units”) each comprised of (a) one share of the Company’s Class A common stock and (b) a warrant (“Common Warrant”) to purchase one and one half shares of Class A Common Stock, and (ii) 503,058 units (the “Prefunded Units”), each comprised of (a) a prefunded warrant (“Prefunded Warrant”) to purchase one share of Class A Common Stock, and (b) a Common Warrant. The Common Units were sold at a purchase price of $1.4275 per unit, and the Prefunded Units were sold at a purchase price of $1.4265 per unit, for aggregate gross proceeds of approximately $10.5 million, before deducting offering expenses. Each Common Warrant is exercisable at any time until the earlier of (a) 30 trading days after the clearance by the FDA of the Company’s CanGarooRM antibiotic-eluting biologic envelope or (b) five years from the date of the offering, at an exercise price per share of $1.4275. Each Prefunded Warrant is exercisable at any time at a nominal exercise price per share of $0.001 (with the remainder of the exercise price per share of Class A Common Stock having been prefunded to the Company).

The Company incurred transaction fees, including commissions and legal fees, of approximately $1.1 million in connection with the private placement, of which $0.4 million were allocated to the issuance of the common stock. See below for discussion of the accounting for warrants and the allocation of the remainder of the transaction fees.

Warrant Liabilities

The Company has concluded that the Common Warrants and the Prefunded Warrants (collectively, the “Offering Warrants”) do not meet the equity contract scope exception under ASC 815-40 as in the event of a (i) fundamental transaction such as a merger and (ii) failure to timely delivery warrant shares upon exercise, certain provisions may require the Company to adjust the settlement value that is not consistent with a fixed-for-fixed option pricing model. As a result, as of the September 21, 2023 issuance date, the Company allocated $8.6 million of the gross proceeds from the offering to the Offering Warrants based on their fair value, and the remaining $1.9 million was allocated to the common shares and recorded as permanent equity. The liability associated with the Offering Warrants is recorded as warrant liability in the accompanying consolidated balance sheet as of December 31, 2023.

The valuation of the Offering Warrants is adjusted to fair value (Level 3) at each subsequent balance sheet date until the warrants are settled. To this end, due primarily to fluctuations in the Company’s underlying common stock price between the issuance date of the Offering Warrants and December 31, 2023, the warrant liability was revalued to $12.8 million as of December 31, 2023. The change in fair value of $4.2 million has been recorded as other expense (income), net in the accompanying consolidated statements of operations for the year ended December 31, 2023.

The Company also allocated a portion of the transaction fees noted above to the Offering Warrants and expensed within other expense (income), net, approximately $0.7 million of these fees.

The Company calculated the fair value of the Offering Warrants using the Black-Scholes option pricing model with the following inputs:


		September 21, 2023			December 31, 2023
Common stock price	$	1.53		$	2.16
Expected term (years)		0.9			0.7
Risk-free interest rate		5.5	%		5.1	%
Volatility factor		117.4	%		107.3	%
Dividend yield		—	%		—	%

The expected term of the Offering Warrants is based on a significant unobservable input, the Company’s probability-weighted expectations relative to the timing of the clearance by the U.S. Food & Drug Administration of the Company’s CanGarooRM antibiotic-eluting biologic envelope.

Public Offering of Common Stock

On December 1, 2022, the Company issued and sold 2,350,000 shares of its Class A common stock at a price to the public of $4.75 per share in a registered underwritten public offering, resulting in net proceeds to the Company of approximately $10.2 million, after deducting underwriting discounts and offering expense.

*Net Present Value; see discussion of value below

The warrant liability in the table above consisted of the fair value of Offering Warrants (as defined in Note 14 below) to purchase the Company’s Class A Common Stock and was based on significant inputs not observable on the market, which represents a Level 3 measurement within the fair value hierarchy. See Note 14 for discussion of the Company’s valuation methods and related impacts on the consolidated statement of operations with respect to the warrant liability.

The Company has estimated the value of the Initial Revenue Interest Obligation as of December 31, 2023 and 2022, including contingent milestone payments and estimated sales-based payments, based on assumptions related to future sales of the acquired products. At each reporting period, the value of the Revenue Interest Obligation is re-measured based on current estimates of future payments, with changes to be recorded in the consolidated statements of operations using the catch-up method. There was no change to estimated future payments during the year ended December 31, 2023 and thus, no re-measurement gain or loss was recognized.

In connection with our estimation at December 31, 2022, it was determined that the estimated future payments, discounted at the original discount rate, had decreased since the prior estimates. Such decrease was primarily the result of anticipated changes to our strategic partnerships relative to sales of both our CanGaroo and cardiovascular product lines that were expected to impact the timing and extent of such sales and, thereby, were expected to reduce expected future payments to Ligand. The change to estimated future payments yielded a reduction to the total Revenue Interest Obligation of approximately $5.0 million for the year ended December 31, 2022 with such amount recognized as a gain in other expense (income), net in our consolidated statement of operations.

The following table provides a rollforward of the aggregate fair value of the Revenue Interest Obligation and warranty liability categorized with Level 3 inputs for the years ended December 31, 2023 and 2022 (in thousands):

Commitment and Contingencies

Note 17. Commitment and Contingencies

Cook Biotech License and Supply Agreements

Elutia has entered into a license agreement with Cook Biotech Incorporated (“Cook Biotech”) for an exclusive, worldwide license to the porcine tissue for use in the Company’s Cardiovascular and CanGaroo products, subject to certain co-exclusive rights retained by Cook Biotech. The term of such license is through the date of the last to expire of the licensed Cook Biotech patents, which is anticipated to be July 2031. Along with this license agreement, Elutia entered into a supply agreement whereby Cook Biotech would be the exclusive supplier to Elutia of the licensed porcine tissue. Under certain limited circumstances, Elutia has the right to manufacture the licensed product and pay Cook Biotech a royalty of 3% of sales of the Elutia-manufactured tissue. The supply agreement expires on the same date as the related license agreement. No royalties were paid to Cook Biotech during the years ended December 31, 2023 and 2022. Elutia has also entered into an amendment to the Cook Biotech license agreement (the “Cook Biotech Amendment”) in order to add fields of exclusive use. Specifically, the Cook Biotech Amendment provides for a worldwide exclusive license to the porcine tissue for use with neuromodulation devices in addition to cardiovascular devices. The Cook Amendment includes license fee payments of $0.1 million per year in each of the years 2021 through 2026. Such license payments would accelerate if a change in control, as defined, occurs within Elutia. The Company, in its sole discretion, can terminate the license agreement at any time.

In February 2024, it was announced that Cook Biotech was acquired by RTI Surgical, Inc. The Company does not expect the acquisition to affect its supply agreement with Cook Biotech, which the Company understands will continue as a subsidiary of RTI Surgical.

Legal Proceedings

From time to time, the Company may be involved in claims and proceedings arising in the course of the Company’s business. The outcome of any such claims or proceedings, regardless of the merits, is inherently uncertain. The Company records accruals for contingencies when it is probable that a liability has been incurred and the amount can be reasonably estimated. Where the available information is only sufficient to establish a range of probable liability, and no point within the range is more likely than any other, the lower end of the range has been used. When a material loss contingency is reasonably possible, but not probable, the Company does not record a liability, but instead discloses the nature of the matter and an estimate of the loss or range of loss, to the extent such estimate can be made. Accruals recorded are adjusted periodically as assessments change or additional information becomes available, and management's judgments may be materially different than the actual outcomes.

FiberCel Litigation

In June 2021, the Company announced a voluntary recall of a single lot of FiberCel fiber viable bone matrix. Since September 2021, 109 lawsuits or claims have been filed or asserted against the Company. The lawsuits, which have been filed against Elutia, certain Medtronic entities, and others, allege that the plaintiffs were exposed to and/or contracted tuberculosis and/or suffered substantial symptoms and complications following the implantation of FiberCel during orthopedic fusion operations. Such lawsuits were filed in Indiana state court (collectively, the “Indiana State Complaints”); the Superior Court of the State of Delaware (collectively, the “Delaware State Complaints”); the Circuit Court of Maryland (collectively, the “Maryland State Complaints”); the Court of Common Pleas of Ohio (the “Ohio State Complaint”); the U.S. District Court of the Southern District of Ohio (the “Ohio Federal Complaint”); the U.S. District Court for the Western District of North Carolina (“North Carolina Federal Complaint”); the Circuit Court of Florida, and the U.S. District Court for the Northern District and the Southern District of Florida (collectively, the “Florida Complaints”); U.S. District Court for the Eastern District of Michigan (collectively “Michigan Federal Complaints.”); the U.S. District Court for the District of Colorado (“Colorado Federal Complaint”); the U.S. District Court for the District of Oregon (“Oregon Federal Complaint”); the Fayette, Kentucky Circuit Court and the U.S. District Court for the Eastern District of Kentucky (collectively, “Kentucky Complaints.”); the U.S. District Court for the Western District of Louisiana (“Louisiana Federal Complaint”);the Circuit Court of Cook County, Illinois and the U.S. District Court for the Northern District of Illinois (collectively, the “Illinois Complaints”); the U.S. District Court for the Eastern District of Pennsylvania (“Pennsylvania Federal Complaint); the U.S. District Court for the Eastern District of Virginia (“Virginia Federal Complaint”); the U.S. District Court for the Central District of California (“California Federal Complaint”); and the U.S. District Court of Arizona (“Arizona Federal Complaint").

Plaintiffs in the Indiana State Complaints allege a cause of action under Indiana’s Product Liability Act, citing manufacturing defects, defective design and failure to properly warn and instruct, and several of the complaints allege loss of consortium. Plaintiffs in these actions assert that the defendants are strictly liable or have breached the duty of care owed to plaintiffs by failing to exercise reasonable care in designing, manufacturing, marketing and labeling FiberCel and are seeking various types of damages, including economic damages, non-economic damages and loss of consortium. Plaintiffs in one of the Indiana State Complaints allege causes of action for product liability, negligence, breach of express and implied warranties, and punitive damages. Each of the plaintiffs in the Delaware State Complaints alleges negligence, breach of implied warranty, breach of express warranty, and medical monitoring and punitive damages, and two also allege loss of consortium. Plaintiffs in the Delaware State Complaints are seeking economic, consequential, and punitive damages. The Maryland State Complaints assert claims of negligence, breach of implied warranty, breach of express warranty, medical monitoring, and loss of consortium. The Florida Complaints contain three strict liability claims for defective design, defective manufacture, and failure to warn. A claim for punitive damages is also pled. The Ohio State Complaint alleges causes of action for product liability and negligence and seeks compensatory damages. The Colorado Federal Complaint asserts causes of action for strict product liability, misrepresentation, negligence, breach of express warranty, and breach of implied warranty of merchantability. The Michigan Federal Complaints assert causes of action for negligence, gross negligence breach of implied warranty, breach of express warranty, intentional infliction of emotional

distress, and liability under the res ipsa loquitur doctrine. The Michigan Federal Complaints seek compensatory damages and punitive damages. The North Carolina Federal Complaint alleges causes of action for negligence, defective design, breach of implied warranty, breach of express warranty, and loss of consortium, and seeks both compensatory and punitive damages. The Oregon Federal Complaint asserts strict liability claims for defective design, defective manufacture, and failure to warn, and seeks compensatory damages. The Ohio Federal Complaint asserts strict liability claims for defective manufacturing, inadequate warning, nonconformance with representations, and also alleges loss of consortium and seeks compensatory damages. The Kentucky Complaints assert strict liability claims based on manufacturing defect, design defect, failure to warn, negligence, breach of implied warranty, breach of express warranty, and seek recovery for medical monitoring, loss of consortium, compensatory damages, and punitive damages. The Louisiana Federal Complaint asserts claims of violation of the Louisiana products liability act, negligence and gross negligence, breach of implied warranty, breach of express warranty and seek recovery for medical monitoring. The Illinois Complaints contain claims of strict liability, defective design and manufacturing, breach of express warranty, breach of implied warranty and negligence and seek compensatory damages. Plaintiff in the Pennsylvania Federal Complaint asserts claims for strict liability, negligence, breach of implied warranty, and breach of express warranty, as well as claims under the Wrongful Death Act and the Survival Act and seeks compensatory and punitive damages. The Virginia Federal Complaint asserts causes of action for negligent failure to warn, negligence, breach of implied warranty, breach of express warranty and seeks recovery for medical monitoring, compensatory damages and punitive damages. The California Federal Complaint advances claims of strict liability (defective design and manufacture), negligence and breach of implied warranty and seeks compensatory damages and recovery for medical monitoring. The Arizona Federal Complaint asserts strict product liability claims for defective design, manufacture and failure to warn, negligence, breach of implied warranty and breach of express warranty and seeks recovery for medical monitoring, loss of consortium, compensatory damages, and punitive damages.

The Company refers to all of the aforementioned litigation, or claim notices, collectively as the “FiberCel Litigation.”

Since August 2022, the Company has engaged in a process to negotiate and attempt to resolve many of the cases in the FiberCel Litigation. In total, Elutia’s liability in 29 of the cases was settled for a total cash outlay of approximately $9.1 million. For the remaining 80 cases for which settlements have not been reached, the Company estimated a probable loss related to each case and has recorded a liability at an estimated amount of $15.0 million at December 31, 2023, which is recorded as Contingent liability for FiberCel litigation in the accompanying consolidated balance sheets. In order to reasonably estimate the liability for the unsettled FiberCel Litigation cases, the Company, along with outside legal counsel, has assessed a variety of factors, including (i) the extent of the injuries incurred, (ii) recent experience on the settled claims, (iii) settlement offers made to the other parties to the litigation and (iv) any other factors that may have a material effect on the FiberCel Litigation. While the Company believes its estimated liability to be reasonable, the actual loss amounts are highly variable and are dependent upon the relevant facts and case by case resolutions. As more information is learned about asserted claims and potential future trends, adjustments may be made to this Contingent Liability for FiberCel Litigation as appropriate. Management believes that it is reasonably possible that the Company could incur liabilities in excess of amounts accrued and the ultimate liability could be material to the results of operations and the cash flows in the period recognized. The Company, however, is unable to estimate the possible loss or range of loss in excess of the amount recognized at this time.

Defense costs are recognized in the accompanying consolidated statements of operations as incurred.

The Company has purchased insurance coverage that, subject to common contract exclusions, provided coverage for the FiberCel Litigation product liability losses as well as legal defense costs. Additionally, the Company has various potential indemnity and/or contribution rights against third party sources with respect to certain product liability losses. When settlements are reached and/or amounts are recorded in the related Contingent Liability for FiberCel Litigation, the Company calculates amounts due to be reimbursed pursuant to the terms of the coverage and related agreements, and pursuant to other indemnity or contribution claims, in respect of product liability losses and related defense costs. The amounts probable of reimbursement or recovery from this calculation are recorded as receivables. The determination that the recorded receivables are probable of collection is based on the terms of agreements reached in respect of indemnity and contribution claims as well as the advice of the Company’s outside legal counsel. These receivables at December 31, 2023 totaled $2.7 million and are recorded as Receivables of FiberCel Litigation Costs in the accompanying consolidated balance sheets.

The indemnity and contribution receivables amount at December 31, 2023 represents amounts that are not believed to be subject to any current dispute. At December 31, 2023, the Company continues to pursue up to $3.8 million or more in additional amounts in respect of such indemnity and contribution claims and as such, has not been reflected as part of this receivable. The Company will vigorously pursue its position with respect to this amount.

Viable Bone Matrix Recall

In July 2023, the Company announced a voluntary recall of a single lot of a certain viable bone matrix (“VBM”) product and the market withdrawal of all of its VBM products produced after a specified date (the “VBM Recall”). Notice of the voluntary recall was issued to centers after the Company learned of post-surgical Mycobacterium tuberculosis (“MTB”) infections in two patients treated with a VBM product from a single donor lot. Prior to release, samples from this specific lot had tested negative for MTB by an independent laboratory using a nucleic acid test that is designed to specifically detect the MTB organism. At present, two lawsuits have been filed, and 15 claims have been asserted as a result of the VBM Recall.

Management has determined that there is a reasonably possible likelihood of material claims due to the VBM Recall, but does not believe that an estimate of the loss or range of loss can be made. This is mainly due to the early stages of the lawsuits and claims and the lack of receipt by the Company of the medical records needed to assess any possible loss. Consequently, management has determined that no probable liability for such possible claims would be recognized for the VBM Recall as of December 31, 2023. While unknown at this time, possible losses in connection with the VBM Recall could have a material effect on the Company’s financial position and results of operations. Consistent with the FiberCel Litigation above, the Company has purchased insurance coverage that, subject to common contract exclusions, provide coverage for the possible claims associated with the VBM Recall as well as legal defense costs. As of December 31, 2023, the Company has recorded a legal fee liability and related insurance receivable totaling $0.1 million for legal services rendered in defending Elutia in the VBM Recall.

As of both December 31, 2023 and 2022, the Company was not a party to, or aware of, any legal matters or claims with material financial exposure, except for the FiberCel Litigation and the VBM Recall.

Note 9. Intangible Assets

On May 31, 2017, the Company completed an asset purchase agreement with CorMatrix Cardiovascular, Inc. (“CorMatrix”) and acquired all CorMatrix commercial assets and related intellectual property. A substantial portion of the assets acquired consisted of intangible assets related to the acquired products and customer relationships. Management determined that the estimated acquisition-date fair values of the intangible assets related to acquired products and customer relationships were $29.3 million and $4.7 million, respectively.

The components of identified intangible assets as of December 31, 2023 and 2022 are as follows (in thousands):


	December 31, 2023						December 31, 2022
			Accumulated						Accumulated
	Cost		Amortization		Net		Cost		Amortization		Net

Total	$	34,040	$	(22,369)	$	11,671	$	34,040	$	(18,971)	$	15,069

Acquired products and customer relationships are both amortized over a ten-year period. Amortization expense totaled approximately $3.4 million for each of the years ended December 31, 2023 and 2022, which is included in cost of

goods sold in the accompanying consolidated statements of operations. Annual amortization expense is expected to be approximately $3.4 million during the years ended December 31, 2024 through 2026 and approximately $1.5 million during the year ended December 31, 2027.

Stock-Based Compensation

Note 5. Stock-Based Compensation

In 2015, the Company established the Elutia Inc. 2015 Stock Option/Stock Issuance Plan, as amended (the “2015 Plan”) which provided for the granting of incentive and non-qualified stock options to employees, directors and consultants of the Company. On October 7, 2020, in connection with the Company’s IPO, the Company adopted the Elutia Inc. 2020 Incentive Award Plan, and on June 8, 2023, the Company’s stockholders approved the amendment and restatement of that plan (as amended and restated, the “2020 Plan”), which authorizes the grant of incentive and non-qualified stock options, restricted stock, restricted stock units and stock appreciation rights to employees, directors and consultants. Shares of Class A common stock totaling 1,636,000 were initially reserved for issuance pursuant to the 2020 Plan, and in June 2023, the number of shares of Class A common stock reserved for issuance under the 2020 Plan was increased by 2,000,000 shares. In addition, the shares reserved for issuance under the 2020 Plan also include shares reserved but not issued under the 2015 Plan as well as an annual increase as set forth in the 2020 Plan. As of December 31, 2023, the Company had 3,401,678 shares of Class A common stock available for issuance under the 2020 Plan, and on January 1, 2024, the shares available for issuance were increased by 927,904 pursuant to the automatic increase provisions of the plan. On January 31, 2024, we granted stock options covering 1,615,561 shares of Class A common stock and restricted stock units covering 2,267,500 shares of Class A common stock to employees and consultants under the 2020 Plan.

Stock Options

The Company’s policy is to grant stock options at an exercise price equal to 100% of the market value of a share of Class A common stock at closing on the date of the grant. The Company’s stock options have contractual terms of ten years, and generally vest over a four-year period from the date of grant.

A summary of stock option activity under the Company’s 2015 Plan and 2020 Plan for the years ended December 31, 2023 is as follows:


				Weighted-
				Average
		Weighted-		Remaining		Aggregate
		Average		Contractual		Intrinsic
		Exercise		Term		Value
	Number of Shares	Price		(years)		(in thousands)
Outstanding, December 31, 2022	1,864,739	$	9.41		7.5	$	8
Granted	157,500	$	2.64
Exercised	—	$	—
Forfeited	(521,046)	$	10.36
Outstanding, December 31, 2023	1,501,193	$	8.37		7.8	$	-
Vested and exercisable, December 31, 2023	786,058	$	10.00		7.1	$	-

As of December 31, 2023, there was approximately $1.9 million of total unrecognized compensation expense related to unvested stock options. These costs are expected to be recognized over a weighted- average period of 1.9 years. The weighted average grant date fair value of options granted during the years ended December 31, 2023 and 2022 were $1.63 and $3.30, respectively. The total intrinsic value of options exercised was not material for both the years ended December 31, 2023 and 2022.

The Company uses the Black-Scholes model to value its stock option grants that vest based on the passage of time or the achievement of certain performance criteria and expenses the related compensation cost using the straight-line method over the vesting period. The fair value of stock options is determined on the grant date using assumptions for the estimated fair value of the underlying common stock, expected term, expected volatility, dividend yield, and the risk-free interest rate. Before the completion of the Company’s IPO, the Board of Directors determined the fair value of common stock considering the state of the business, input from management, third party valuations and other considerations. The Company uses the simplified method for estimating the expected term used to determine the fair value of options. The expected volatility of the Class A common stock is partially based on the historical volatility of comparable companies in the industry whose share prices are publicly available. The Company uses a zero-dividend yield assumption as the Company has not paid dividends since inception nor does it anticipate paying dividends in the future. The risk-free interest rate approximates recent U.S. Treasury note auction results with a similar life to that of the option. The period expense is then determined based on the valuation of the options and is recognized on a straight-line basis over the requisite service period for the entire award.

The following weighted-average assumptions were used to determine the fair value of options during the years ended December 31, 2023 and 2022:


	Year Ended
	December 31,
	2023		2022
Expected term (years)	6.0		6.2
Risk-free interest rate	3.9	%	2.3	%
Volatility factor	63.8	%	63.8	%
Dividend yield	—		—

The Company has also granted to President and Chief Executive Officer stock options that vest in equal installments upon the achievement of certain share price thresholds for twenty consecutive days of trading at each respective threshold. For these stock options, the Company accounted for the awards as market condition awards and used an option pricing model, the Monte Carlo model, to determine the fair value of the respective equity instruments and an expense recognition term of approximately three years. As of December 31, 2023, there are 182,511 stock options outstanding that are market condition stock option awards.

Restricted Stock Units

Restricted stock units (“RSUs”) represent rights to receive common shares at a future date. There is no exercise price and no monetary payment is required for receipt of restricted stock units or the shares issued in settlement of the award.

A summary of the RSU activity under the Company’s 2020 Plan for the year ended December 31, 2023 is as follows:


		Weighted-
		Average
	Number of Shares	Grant Date
	Underlying RSUs	Fair Value
Unvested, December 31, 2022	372,307	$	5.90
Granted	122,000	$	2.12
Vested	(75,996)	$	11.69
Forfeited	(82,703)	$	3.93
Unvested, December 31, 2023	335,608	$	3.64

The total fair value of the RSUs granted during the year ended December 31, 2023 and 2022 of $0.3 million and $2.4 million, respectively was based on the fair market value of the Company's Class A common stock on the date of grant. The fair value at the time of the grant is amortized to expense on a straight-line basis over the vesting period of three to four years.

The Company has also granted to President and Chief Executive Officer RSUs that vest in equal installments upon the achievement of certain share price thresholds for twenty consecutive days of trading at each respective threshold. For these RSUs, the Company accounted for the awards as market condition awards and used a Monte Carlo model to determine the fair value of these RSUs as well as the expense recognition term of two to three years using the graded vesting method. As of December 31, 2023, there were 89,894 RSUs outstanding that were market condition RSU awards.

As of December 31, 2023, $0.8 million of unrecognized compensation costs related to RSUs is expected to be recognized over a weighted average period of approximately two years.

Employee Stock Purchase Plan

The Company makes shares of its Class A common stock available for purchase under the Elutia Inc. 2020 Employee Stock Purchase Plan (the “ESPP”). The ESPP provides for separate six-month offering periods that begin in March and September of each year. Under the ESPP, employees may purchase a limited number of shares of Elutia Class A common stock at 85% of the fair market value on either the first day of the offering period or the purchase date, whichever is lower. The ESPP is considered compensatory for purposes of stock-based compensation expense. The number of shares reserved under the ESPP will automatically increase on the first day of each fiscal year through January 1, 2030, in an amount equal to the lesser of (i) 1% of the total shares of Class A common stock outstanding on the final day of the immediately preceding calendar year; or (ii) a lesser number of shares determined by the Company’s board of directors. As of December 31, 2023, the total shares of Class A common stock authorized for issuance under the ESPP was 542,365 of which 335,808 remained available for future issuance. During the year ended December 31, 2023, 104,905 shares of Class A common stock were issued under the ESPP.

Income Taxes

Income Taxes

Income Taxes

Note 13. Income Taxes

The Company is subject to income taxes in the United States. Income taxes are accounted for under the asset and liability method. Deferred income tax assets and liabilities are calculated based on the difference between the financial

statement carrying amounts of existing assets and liabilities and their respective tax bases using the enacted income tax rates expected to be in effect during the years in which the temporary differences are expected to reverse.

The reconciliation of the U.S. federal statutory rate to the consolidated effective tax rate is as follows:


	Years Ended December 31,
	2023		2022
Tax benefit at U.S. statutory rate	21.0	%	21.0	%
State income tax benefit, net of federal benefit	1.8	%	1.9	%
Nondeductible expenses	(2.8)	%	(0.3)	%
State law changes	0.6	%	0.5	%
Other	(1.4)	%	0.1	%
Change in valuation allowance	(19.3)	%	(23.3)	%
Income tax expense	(0.1)	%	(0.1)	%

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes as well as net operating loss carryforwards. As of December 31, 2023 and 2022, significant components of the Company’s net deferred income taxes are as follows (in thousands):


	December 31,
	2023		2022
Deferred tax assets:
Tax goodwill	$	2,613	$	2,947
Net operating loss carryforwards		23,325		19,743
Inventory		137		491
Acquired intangibles		1,734		1,452
Revenue interest obligation		1,220		774
Interest expense		3,510		2,533
Research and development costs		2,412		1,749
Operating lease liability		52		364
FiberCel litigation costs		2,867		669
Other		1,653		2,045
Total assets		39,523		32,767
Deferred tax liabilities:
Operating lease right-to-use assets		(51)		(350)
Prepaid expenses		(484)		(562)
Total liabilities		(535)		(912)

Total net deferred tax asset		38,988		31,855
Valuation allowance		(38,988)		(31,855)
Net deferred tax asset, net of valuation allowance	$	—	$	—

The Company did not recognize any deferred benefit for income taxes for the years ended December 31, 2023 and 2022, as the increases to the respective net deferred tax assets of $7.1 million and $7.6 million, respectively, were offset by corresponding increases to the Company’s deferred tax asset valuation allowance due to uncertainty of realizing the deferred tax assets.

The Company evaluates the need for deferred tax asset valuation allowances based on a more likely than not standard. The ability to realize deferred tax assets depends on the ability to generate sufficient taxable income within the carryback or carryforward periods provided for in the tax law for each applicable tax jurisdiction. Valuation allowances are established when necessary to reduce deferred tax assets to amounts that are more likely than not to be realized. Based on the uncertainty of future taxable income generation, as of December 31, 2023 and 2022, the Company has provided valuation allowances against all deferred tax assets.

The Company regularly assesses the realizability of its deferred tax assets. Changes in historical earnings performance and future earnings projections, among other factors, may cause the Company to adjust its valuation allowance, which would impact the Company’s income tax expense in the period the Company determines that these factors have changed.

The income tax expense for the years ended December 31, 2023 and 2022 relates to current amounts due on certain state tax obligations.

As of December 31, 2023, the Company had net operating loss carryforwards for federal income tax purposes of approximately $102.1 million, comprised of $17.7 million that will expire beginning in 2036 and $84.4 million that have no expiration date. The Company also had state net operating loss carryforwards of approximately $33.5 million that will expire beginning in 2030. Utilization of the net operating loss carryforwards may be subject to an annual limitation under Section 382 of the Code, and corresponding provisions of state law, due to ownership changes that have occurred previously or that could occur in the future. These ownership changes may limit the amount of carryforwards that can be utilized annually to offset future taxable income. The Company has not conducted a study to assess whether a change of control has occurred or whether there have been multiple changes of control since inception due to the significant complexity and cost associated with such a study. If the Company has experienced a change of control, as defined by Section 382, at any time since inception, utilization of the net operating loss carryforwards would be subject to an annual limitation under Section 382. Any limitation may result in expiration of a portion of the net operating loss carryforwards before utilization.

As of December 31, 2023 and 2022, the Company had no unrecognized tax benefits.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
