Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited Consolidated Financial Statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the Consolidated Financial Statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of the results for the interim periods presented. The information included in this quarterly report on Form 10-Q should be read in conjunction with the audited Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year-ended December 31, 2023 filed with the SEC on February 22, 2024 and the Australian Securities Exchange ("ASX") on February 23, 2024 (the “2023 Annual Report"). Except for revenue recognition, related to the RECELL GO system, as described below, there have been no changes to the Company’s significant accounting policies as described in the 2023 Annual Report that have had a material impact on the Company’s Consolidated Financial Statements. See the summary of the Company’s significant accounting policies set forth in the notes to its Consolidated Financial Statements included in the 2023 Annual Report. Principles of Consolidation The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation. Recent Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly reviewed by the Chief Operating Decision Maker ("CODM") and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The ASU also allows, in addition to the measure that is most consistent with GAAP, the disclosure of additional measures of segment profit or loss that are used by the CODM in assessing segment performance and deciding how to allocate resources. All disclosure requirements under ASU 2023-07 are also required for public entities with a single reportable segment. The ASU is effective for the Company’s 2023 Annual Report on Form 10-K for the fiscal year ending December 31, 2025, and subsequent interim periods, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments affected by this ASU require (i) enhanced disclosures in connection with an entity's effective tax rate reconciliation and (ii) income taxes paid disaggregated by jurisdiction. These amendments are effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures. Use of Estimates The preparation of the accompanying Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts (including estimate of the average selling price for PermeaDerm sales, stand-alone selling price ("SSP") for the RPD, allowance for credit losses, reserves for inventory excess and obsolescence, carrying value of long-lived assets, the useful lives of long-lived assets, accounting for marketable securities, income taxes, fair value of debt, fair value of warrants and stock-based compensation) and related disclosures. Estimates have been prepared based on the current and available information. However, actual results could differ from estimated amounts. Foreign Currency Translation and Foreign Currency Transactions The financial position and results of operations of the Company’s operating non-U.S. subsidiaries are generally determined using the respective local currency as the functional currency of that subsidiary. Assets and liabilities of these subsidiaries are translated at the exchange rate in effect at each period end. Income statement accounts are translated at the average rate of exchange prevailing during the period. Adjustments arising from the use of differing exchange rates from period to period are included in Other comprehensive gain (loss) in Stockholders’ Equity. The Company’s non-operating subsidiaries that use the U.S. dollar as their functional currency remeasure monetary assets and liabilities at exchange rates in effect at the end of each period and nonmonetary assets and liabilities at historical rates. Gains and losses resulting from these remeasurements are included in earnings in the Consolidated Statement of Operations. Gains and losses for remeasurement were minimal during the three-months and six-months ended June 30, 2024 and 2023. The Company records certain revenues and operating expenses in foreign currencies. These revenues and expenses are translated into U.S. Dollars based on the average exchange rate for the reporting period. Assets and liabilities denominated in foreign currencies are translated into U.S. Dollars at the exchange rate in effect as of the balance sheet date. For the three and six-months ended June 30, 2024, the Company incurred approximately $7,000 and $12,000 in losses included in net loss in the Consolidated Statement of Operations, respectively. For the three and six-months ended June 30, 2023 transactions gains and losses were minimal. Cash and Cash Equivalents Cash and cash equivalents consist of cash held at deposit institutions and cash equivalents. Cash equivalents consist primarily of money market funds. Cash equivalents also include short-term highly liquid investments with original maturities of three months or less from the date of purchase. The Company holds cash at deposit institutions in the amount of $6.6 million and $10.7 million as of June 30, 2024 and December 31, 2023, respectively. The Company does not have cash on deposit denominated in foreign currency in foreign institutions as of June 30, 2024. As of December 31, 2023, the Company had $69,000 of cash on deposit denominated in foreign currencies in foreign institutions. As of June 30, 2024 and December 31, 2023, the Company held cash equivalents in the amount of $10.8 million and $11.4 million, respectively. Concentrations Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, trade receivables and debt and other liabilities. As of June 30, 2024 and December 31, 2023, substantially all the Company’s cash was deposited in accounts at financial institutions, and amounts exceed federally insured limits and are subject to the risk of bank failure. As of June 30, 2024 and December 31, 2023, no single commercial customer accounted for more than 10% of net accounts receivable or more than 10% of revenues for the three-months and six-months ended June 30, 2024 and 2023. Revenue Recognition The Company generates revenues primarily from the sale of: • RECELL EOU, RPK, and PermeaDerm products to hospitals, other treatment centers, and distributors. • Maintenance fee received from BARDA to ensure first right of access to our inventory. In the prior year, the Company recorded service revenue for the emergency preparedness services provided to BARDA. • Lease revenue for the RPD. The Company’s sale of the RECELL EOU and PermeaDerm products are accounted for under ASC 606, Revenue from contracts with customers (“ASC 606”). Revenue for the RECELL GO system is disaggregated between two accounting standards: (1) ASC 606 for the RPK and (2) ASC 842, Leases ("ASC 842") for the RPD. Revenues from BARDA, are accounted for under ASC 606, and are included in Sales revenues within the Consolidated Statements of Operations. To determine revenue recognition for contracts that are within the scope of ASC 606, the Company performs the following five steps: 1. Identify the contract with a customer 2. Identify the performance obligations 3. Determine the transaction price 4. Allocate the transaction price to the performance obligations 5. Recognize revenue when/as a performance obligation(s) is(are) satisfied In order for an arrangement to be considered a contract, it must be probable that the Company will collect the consideration to which it is entitled for goods or services to be transferred. The Company then assesses the goods or services promised within the contract to determine whether each promised good or service is a performance obligation. Performance obligations are promises in a contract to transfer a distinct good or service to the customer that (i) the customer can benefit from on its own or together with other readily available resources, and (ii) is separately identifiable from other promises in the contract. The Company determines the transaction price based on the amount of consideration the Company expects to receive for transferring the promised goods or services in the contract. Consideration may be fixed, variable, or a combination of both. At contract inception for arrangements that include variable consideration, the Company estimates the probability and extent of consideration it expects to receive under the contract utilizing either the most likely amount method or expected amount method, whichever best estimates the amount expected to be received. The Company then considers any constraints on the variable consideration and includes in the transaction price variable consideration to the extent it is deemed probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. When accounting for a contract that contains multiple performance obligations, the Company must develop judgmental assumptions to determine the estimated SSP for each performance obligation identified in the contract. We utilize the observable SSP when available, which represents the price charged for the promised product or service when sold separately. When the SSP for our products or services are not directly observable, we determine the SSP using relevant information available and apply suitable estimation methods including, but not limited to, the cost-plus margin approach. The Company then allocates the transaction price to each performance obligation based on the relative SSP and recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) control is transferred to the customer and the performance obligation is satisfied. Most of the Company’s contracts have a single performance obligation. As such, the Company recognizes revenue when its customers obtain control of promised goods or services, in an amount that reflects the consideration which the Company expects to be entitled in exchange for those goods or services. Revenue is recognized net of volume discounts (variable consideration). For the Company’s contracts that have an original duration of one year or less, the Company elected the practical expedient applicable to such contracts and does not consider the time value of money. Further, because of the short duration of these contracts, the Company has not disclosed the transaction price for the remaining performance obligations as of each reporting period or when the Company expects to recognize this revenue. The Company has further applied the practical expedient to exclude sales tax in the transaction price and expense contract acquisition costs such as commissions and shipping and handling expenses as incurred. Revenue recognition for contracts that are within the scope of ASC 606 and ASC 842 The Company enters into contracts with customers where it receives consideration for the RPK and does not receive additional consideration for the RPD. As a result, judgment and analysis are required to determine the appropriate accounting, including: (i) whether the arrangement contains an embedded lease, and if so, whether such embedded lease is a sales-type lease or an operating lease, (ii) the amount of the total consideration, as well as variable consideration, (iii) the identification of the distinct performance obligations contained within the arrangement, (iv) how the arrangement consideration should be allocated to each performance obligation when multiple performance obligations exist, including the determination of standalone selling price, and (v) when to recognize revenue on the performance obligations. For these contracts the Company considers the guidance under ASC 842 to determine if furnishing the RPD to the customer during the period of use establishes an embedded lease. To determine if the contract contains a lease, the Company evaluates the customer’s rights and ability to control the use of the underlying equipment throughout the contract term, including any equipment substitution rights retained by the Company. As the contract conveys the right to control the use of an identified asset for a period of time, the contract was determined to contain a lease. The Company then evaluated the lease classification based on the below: • Pursuant to ASC 842-30, the Company will classify a lease as a sales-type lease if: (i) the lease transfers ownership of the underlying asset to the lessee by the end of the lease term, (ii) the lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise, (iii) the lease term is for the major part of the remaining economic life of the underlying asset, (iv) the present value of the sum of the lease payments and any residual value guaranteed by the lessee that is not already reflected in the lease payments equals or exceeds substantially all (90% or more) of the fair value of the underlying asset, or (v) the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. • Pursuant to ASC 842-30, when none of the sales-type lease classification criteria are met, a lessor would classify the lease as a direct financing lease when both of the following criteria are met: (i) the present value of the sum of the lease payments and any residual value guaranteed by the lessee that is not already reflected in the lease payments and/or any other third party unrelated to the lessor equals or exceeds substantially all (90% or more) of the fair value of the underlying asset and (ii) it is probable that the lessor will collect the lease payments plus any amount necessary to satisfy a residual value guarantee. • Pursuant to ASC 842-30, a lessor would classify a lease as an operating lease when none of the sales-type or direct financing lease classification criteria are met. Further, per ASC 842, a lessor is required to classify a lease with variable lease payments that do not depend on an index or rate as an operating lease at lease commencement if the lease would have been classified as a sales-type lease or a direct financing lease in accordance with the classification criteria of ASC 842 and the lessor would have otherwise recognized a loss at inception. In determining whether the lease components are related to a sales-type lease or an operating lease, the Company evaluates if the lease transfers ownership at the end of the lease term, purchase options, the lease term in relation to the economic life of the asset, if the lease payments exceed the fair value of the asset, and if the asset is of a specialized nature. The Company also evaluates if the lease results in a loss at inception. As the lease term is for the major part of the economic life, the lease meets the classification criteria for sales-type lease. However, to determine if the contract results in a loss at lease inception we evaluated the consideration in the contract. The consideration at lease commencement does not contain fixed payments, purchase options, penalty payments or residual value guarantees. The variable consideration is related to the sale of the RPK. As the variable lease payments are not dependent on an index or rate, the variable consideration is excluded from consideration at contract inception resulting in a loss at lease commencement. As such, the Company classifies the lease as an operating lease. The contracts contain a lease component, the RPD, and a nonlease component, the RPK. The lease component will be accounted for under the ASC 842 and the nonlease component will be accounted for under ASC 606, as described above. In accordance with ASC 842, the consideration in the contract will be allocated to each separate lease component and nonlease component of the contract. The consideration is allocated to these lease and non-lease components based on the SSP (as described above for contracts with-in the scope of ASC 606). In accordance with ASC 842, variable consideration will be recognized once the sale of the RPK occurs. Consideration will be allocated to the RPD and RPK based on the SSP. Consideration related to the RPD will be recognized as Lease revenue and consideration related to the RPK will be recognized as Sales revenues in accordance with guidance in ASC 606, as described above, upon transfer of control of the product. Assets in our lease program are reported in Plant and equipment, net on our Consolidated Balance Sheets and are depreciated over the useful life of the RPD devices 200 uses, as indicated in the Instructions for Use that were approved by the FDA, and expensed as Costs of goods sold in the Consolidated Statements of Operations. The RPD depreciation has a direct relationship to the number of RPK units sold. Based on customer usage, each purchase of an RPK unit results in a 1/200 depreciation to the RPD.

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited Consolidated Financial Statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the Consolidated Financial Statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of the results for the interim periods presented. The information included in this quarterly report on Form 10-Q should be read in conjunction with the audited Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year-ended December 31, 2023 filed with the SEC on February 22, 2024 and the Australian Securities Exchange ("ASX") on February 23, 2024 (the “2023 Annual Report").

Except for revenue recognition, related to the RECELL GO system, as described below, there have been no changes to the Company’s significant accounting policies as described in the 2023 Annual Report that have had a material impact on the Company’s Consolidated Financial Statements. See the summary of the Company’s significant accounting policies set forth in the notes to its Consolidated Financial Statements included in the 2023 Annual Report.

Principles of Consolidation

The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation.

Recent Accounting Pronouncements

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly reviewed by the Chief Operating Decision Maker ("CODM") and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The ASU also allows, in addition to the measure that is most consistent with GAAP, the disclosure of additional measures of segment profit or loss that are used by the CODM in assessing segment performance and deciding how to allocate

resources. All disclosure requirements under ASU 2023-07 are also required for public entities with a single reportable segment. The ASU is effective for the Company’s 2023 Annual Report on Form 10-K for the fiscal year ending December 31, 2025, and subsequent interim periods, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments affected by this ASU require (i) enhanced disclosures in connection with an entity's effective tax rate reconciliation and (ii) income taxes paid disaggregated by jurisdiction. These amendments are effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.

Use of Estimates

The preparation of the accompanying Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts (including estimate of the average selling price for PermeaDerm sales, stand-alone selling price ("SSP") for the RPD, allowance for credit losses, reserves for inventory excess and obsolescence, carrying value of long-lived assets, the useful lives of long-lived assets, accounting for marketable securities, income taxes, fair value of debt, fair value of warrants and stock-based compensation) and related disclosures. Estimates have been prepared based on the current and available information. However, actual results could differ from estimated amounts.

Foreign Currency Translation and Foreign Currency Transactions

The financial position and results of operations of the Company’s operating non-U.S. subsidiaries are generally determined using the respective local currency as the functional currency of that subsidiary. Assets and liabilities of these subsidiaries are translated at the exchange rate in effect at each period end. Income statement accounts are translated at the average rate of exchange prevailing during the period. Adjustments arising from the use of differing exchange rates from period to period are included in Other comprehensive gain (loss) in Stockholders’ Equity.

The Company’s non-operating subsidiaries that use the U.S. dollar as their functional currency remeasure monetary assets and liabilities at exchange rates in effect at the end of each period and nonmonetary assets and liabilities at historical rates. Gains and losses resulting from these remeasurements are included in earnings in the Consolidated Statement of Operations. Gains and losses for remeasurement were minimal during the three-months and six-months ended June 30, 2024 and 2023.

The Company records certain revenues and operating expenses in foreign currencies. These revenues and expenses are translated into U.S. Dollars based on the average exchange rate for the reporting period. Assets and liabilities denominated in foreign currencies are translated into U.S. Dollars at the exchange rate in effect as of the balance sheet date. For the three and six-months ended June 30, 2024, the Company incurred approximately $7,000 and $12,000 in losses included in net loss in the Consolidated Statement of Operations, respectively. For the three and six-months ended June 30, 2023 transactions gains and losses were minimal.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash held at deposit institutions and cash equivalents. Cash equivalents consist primarily of money market funds. Cash equivalents also include short-term highly liquid investments with original maturities of three months or less from the date of purchase. The Company holds cash at deposit institutions in the amount of $6.6 million and $10.7 million as of June 30, 2024 and December 31, 2023, respectively. The Company does not have cash on deposit denominated in foreign currency in foreign institutions as of June 30, 2024. As of December 31, 2023, the Company had $69,000 of cash on deposit denominated in foreign currencies in foreign institutions. As of June 30, 2024 and December 31, 2023, the Company held cash equivalents in the amount of $10.8 million and $11.4 million, respectively.

Concentrations

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, trade receivables and debt and other liabilities. As of June 30, 2024 and December 31, 2023, substantially all the Company’s cash was deposited in accounts at financial institutions, and amounts exceed federally insured limits and are subject to the risk of bank failure.

As of June 30, 2024 and December 31, 2023, no single commercial customer accounted for more than 10% of net accounts receivable or more than 10% of revenues for the three-months and six-months ended June 30, 2024 and 2023.

Revenue Recognition

The Company generates revenues primarily from the sale of:

•

RECELL EOU, RPK, and PermeaDerm products to hospitals, other treatment centers, and distributors.

•

Maintenance fee received from BARDA to ensure first right of access to our inventory. In the prior year, the Company recorded service revenue for the emergency preparedness services provided to BARDA.

•

Lease revenue for the RPD.

The Company’s sale of the RECELL EOU and PermeaDerm products are accounted for under ASC 606, Revenue from contracts with customers (“ASC 606”). Revenue for the RECELL GO system is disaggregated between two accounting standards: (1) ASC 606 for the RPK and (2) ASC 842, Leases ("ASC 842") for the RPD. Revenues from BARDA, are accounted for under ASC 606, and are included in Sales revenues within the Consolidated Statements of Operations.

To determine revenue recognition for contracts that are within the scope of ASC 606, the Company performs the following five steps:

Identify the contract with a customer

Identify the performance obligations

Determine the transaction price

Allocate the transaction price to the performance obligations

Recognize revenue when/as a performance obligation(s) is(are) satisfied

In order for an arrangement to be considered a contract, it must be probable that the Company will collect the consideration to which it is entitled for goods or services to be transferred. The Company then assesses the goods or services promised within the contract to determine whether each promised good or service is a performance obligation. Performance obligations are promises in a contract to transfer a distinct good or service to the customer that (i) the customer can benefit from on its own or together with other readily available resources, and (ii) is separately identifiable from other promises in the contract.

The Company determines the transaction price based on the amount of consideration the Company expects to receive for transferring the promised goods or services in the contract. Consideration may be fixed, variable, or a combination of both. At contract inception for arrangements that include variable consideration, the Company estimates the probability and extent of consideration it expects to receive under the contract utilizing either the most likely amount method or expected amount method, whichever best estimates the amount expected to be received. The Company then considers any constraints on the variable consideration and includes in the transaction price variable consideration to the extent it is deemed probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved.

When accounting for a contract that contains multiple performance obligations, the Company must develop judgmental assumptions to determine the estimated SSP for each performance obligation identified in the contract. We utilize the observable SSP when available, which represents the price charged for the promised product or service when sold separately. When the SSP for our products or services are not directly observable, we determine the SSP using relevant information available and apply suitable estimation methods including, but not limited to, the cost-plus margin approach. The Company then allocates the transaction price to each performance obligation based on the relative SSP and recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) control is transferred to the customer and the performance obligation is satisfied.

Most of the Company’s contracts have a single performance obligation. As such, the Company recognizes revenue when its customers obtain control of promised goods or services, in an amount that reflects the consideration which the Company expects to be entitled in exchange for those goods or services. Revenue is recognized net of volume discounts (variable consideration). For the Company’s contracts that have an original duration of one year or less, the Company elected the practical expedient applicable to such contracts and does not consider the time value of money. Further, because of the short duration of these contracts, the Company has not disclosed the transaction price for the remaining performance obligations as of each reporting period or when the Company expects to recognize this revenue. The Company has further applied the practical expedient to exclude sales tax in the transaction price and expense contract acquisition costs such as commissions and shipping and handling expenses as incurred.

Revenue recognition for contracts that are within the scope of ASC 606 and ASC 842

The Company enters into contracts with customers where it receives consideration for the RPK and does not receive additional consideration for the RPD. As a result, judgment and analysis are required to determine the appropriate accounting, including: (i) whether the arrangement contains an embedded lease, and if so, whether such embedded lease is a sales-type lease or an operating lease, (ii) the amount of the total consideration, as well as variable consideration, (iii) the identification of the distinct performance obligations contained within the arrangement, (iv) how the arrangement consideration should be allocated to each performance obligation when multiple performance obligations exist, including the determination of standalone selling price, and (v) when to recognize revenue on the performance obligations.

For these contracts the Company considers the guidance under ASC 842 to determine if furnishing the RPD to the customer during the period of use establishes an embedded lease. To determine if the contract contains a lease, the Company evaluates the customer’s rights and ability to control the use of the underlying equipment throughout the contract term, including any equipment substitution rights retained by the Company. As the contract conveys the right to control the use of an identified asset for a period of time, the contract was determined to contain a lease. The Company then evaluated the lease classification based on the below:

•

Pursuant to ASC 842-30, the Company will classify a lease as a sales-type lease if: (i) the lease transfers ownership of the underlying asset to the lessee by the end of the lease term, (ii) the lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise, (iii) the lease term is for the major part of the remaining economic life of the underlying asset, (iv) the present value of the sum of the lease payments and any residual value guaranteed by the lessee that is not already reflected in the lease payments equals or exceeds substantially all (90% or more) of the fair value of the underlying asset, or (v) the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term.

•

Pursuant to ASC 842-30, when none of the sales-type lease classification criteria are met, a lessor would classify the lease as a direct financing lease when both of the following criteria are met: (i) the present value of the sum of the lease payments and any residual value guaranteed by the lessee that is not already reflected in the lease payments and/or any other third party unrelated to the lessor equals or exceeds substantially all (90% or more) of the fair value of the underlying asset and (ii) it is probable that the lessor will collect the lease payments plus any amount necessary to satisfy a residual value guarantee.

•

Pursuant to ASC 842-30, a lessor would classify a lease as an operating lease when none of the sales-type or direct financing lease classification criteria are met. Further, per ASC 842, a lessor is required to classify a lease with variable lease payments that do not depend on an index or rate as an operating lease at lease commencement if the lease would have been classified as a sales-type lease or a direct financing lease in accordance with the classification criteria of ASC 842 and the lessor would have otherwise recognized a loss at inception.

In determining whether the lease components are related to a sales-type lease or an operating lease, the Company evaluates if the lease transfers ownership at the end of the lease term, purchase options, the lease term in relation to the economic life of the asset, if the lease payments exceed the fair value of the asset, and if the asset is of a specialized nature. The Company also evaluates if the lease results in a loss at inception. As the lease term is for the major part of the economic life, the lease meets the classification criteria for sales-type lease. However, to determine if the contract results in a loss at lease inception we evaluated the consideration in the contract. The consideration at lease commencement does not contain fixed payments, purchase options, penalty payments or residual value guarantees. The variable consideration is related to the sale of the RPK. As the variable lease payments are not dependent on an index or rate, the variable consideration is excluded from consideration at contract inception resulting in a loss at lease commencement. As such, the Company classifies the lease as an operating lease.

The contracts contain a lease component, the RPD, and a nonlease component, the RPK. The lease component will be accounted for under the ASC 842 and the nonlease component will be accounted for under ASC 606, as described above. In accordance with ASC 842, the consideration in the contract will be allocated to each separate lease component and nonlease component of the contract. The consideration is allocated to these lease and non-lease components based on the SSP (as described above for contracts with-in the scope of ASC 606). In accordance with ASC 842, variable consideration will be recognized once the sale of the RPK occurs. Consideration will be allocated to the RPD and RPK based on the SSP. Consideration related to the RPD will be recognized as Lease revenue and consideration related to the RPK will be recognized as Sales revenues in accordance with guidance in ASC 606, as described above, upon transfer of control of the product.

Assets in our lease program are reported in Plant and equipment, net on our Consolidated Balance Sheets and are depreciated over the useful life of the RPD devices 200 uses, as indicated in the Instructions for Use that were approved by the FDA, and expensed as Costs of goods sold in the Consolidated Statements of Operations. The RPD depreciation has a direct relationship to the number of RPK units sold. Based on customer usage, each purchase of an RPK unit results in a 1/200 depreciation to the RPD.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

13. Commitments and Contingencies

The Company is subject to certain contingencies arising in the ordinary course of business. The Company records accruals for these contingencies to the extent that a loss is both probable and reasonably estimable. If some amount within a range of loss appears more likely than any other amount within the range, that amount is accrued. Alternatively, when no amount within a range of loss appears to be a better estimate than any other amount, the lowest amount in the range is accrued. The Company expenses legal costs associated with loss contingencies as incurred. As of June 30, 2024 and December 31, 2023, the Company did not have any outstanding or threatened litigation that would have a material impact on the financial statements.

Minimum Purchase Commitments with Stedical

The Company is subject to minimum purchase of PermeaDerm product for the initial term of five years. For 2024, the Company has an obligation to purchase a minimum of $5.0 million of inventory from Stedical. For the three and six-months ended June 30, 2024, the Company has purchased $2.6 million in inventory with another $2.4 million of inventory remaining to be purchased. This obligation is not recorded in the Company's Consolidated Balance Sheets. For the first three years of the agreement, the minimum purchase should increase annually by an amount equal to the percentage growth in the Company's annual US based revenues excluding PermeaDerm revenue, or a minimum increase of at least 20% over the prior year purchase commitment. After the third year, the minimum purchase obligation shall increase annually by an amount equal to the percentage growth of the Company's annual U.S.-based revenues excluding PermeaDerm sales. The minimum purchase obligation should never decrease from the previous year.

Revenue, Performance Obligation [Abstract]

Revenues

5. Revenues

The Company generates revenues primarily from the sale of:

•

RECELL Ease of Use ("EOU"), RECELL GO RPK, and PermeaDerm products to hospitals, other treatment centers, and distributors.

•

Maintenance fee received from BARDA in exchange for first right of access to our inventory. In the prior year, the Company recorded service revenues for the emergency preparedness services provided to BARDA.

•

Lease revenue for the RECELL GO RPD.

The Company’s sale of the EOU and PermeaDerm products are accounted for under ASC 606 Revenue from contracts with customers (“ASC 606”). Revenue for the RECELL GO device is disaggregated between two accounting standards: (1) ASC 606 for the RPK and (2) ASC 842 for the RPD.

RECELL GO

The RECELL GO device consists of a single-use RPK and a durable AC powered device, RPD. The Company enters into contracts with customers where it receives consideration for the single-use RPK and does not receive additional consideration for the RPD. The consideration in the contract is allocated based on the SSP. Upon sale of the RPK the consideration is allocated to the lease and nonlease components. Consideration received for the RPK is recorded in Sales revenues in the Consolidated Statement of Operations and consideration for the lease is recorded in Lease revenue in the Consolidated Statement of Operations. During the three and six-months ended June 30, 2024, the Company recorded approximately $613,000 in Sales revenue related to the RPK and $12,000 related to Lease revenue in the Consolidated Statement of Operations, respectively.

Distributor Transactions

For international markets, the Company exclusively partners with third-party distributors (currently, COSMOTEC in Japan, and PolyMedics Innovation GmbH, in Germany). Revenue recognition occurs when the distributors obtain control of the product. The terms of sales transactions through distributors are generally consistent with the terms of direct sales to customers and do not contain return rights. These transactions are accounted for in accordance with the Company’s revenue recognition policy described in Note 2, Summary of Significant Accounting Policies in our Consolidated Financial Statements.

PermeaDerm Sales

As provided in the Stedical Scientific Distribution Agreement, the Company’s gross margin from the sale of PermeaDerm is 50% of the average sales price ("ASP"). The Company and Stedical share the gross revenue from the sale of the products evenly at 50% of ASP. The Company recognizes revenue when the customer obtains control of promised goods, in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods.

Remaining Performance Obligations

Contract liabilities are calculated as the dollar value of the remaining performance obligations on executed contracts and primarily relate to COSMOTEC and other customers. The estimated revenue expected to be recognized in the future once the performance obligation is satisfied under the Company’s existing customer agreements is $545,000 and $390,000 as of June 30, 2024 and December 31, 2023, respectively. These amounts are classified between current and long-term in Other current liabilities and Contract liabilities in the Consolidated Balance Sheets. For current balances refer to Note 11 of our Consolidated Financial Statements.

Contract Assets and Contract Liabilities

Contract assets include amounts related to the Company’s contractual right to consideration for both completed and partially completed performance for which the Company does not have the right to payment. As of June 30, 2024 and December 31, 2023, the Company does not have any contract assets.

Contract liabilities are recorded when the Company receives payment prior to satisfying its obligation to transfer goods to a customer. Contract liability balance primarily relates to unsatisfied performance obligation with COSMOTEC of $374,000 and $390,000 as of June 30, 2024 and December 31, 2023, respectively. This balance is classified between current and long-term. As of June 30, 2024 and December 31, 2023, a total of $34,000 and $33,000, respectively, was included in Other current liabilities and

$340,000 and $357,000, respectively, in Contract liabilities in the Consolidated Balance Sheets. The Company has an additional $171,000 and zero, as of June 30, 2024 and December 31, 2023, respectively, in current contract liabilities not related to COSMOTEC. This balance will be recognized during the third quarter when the performance obligation is satisfied.

The Company recognized approximately $8,000 and $17,000 of revenue from COSMOTEC for amounts included in the beginning balance of Contract liabilities for the three-months and six-months ended June 30, 2024 and 2023, respectively.

Disaggregated Revenue

The Company disaggregates revenue from contracts with customers into geographical regions, by customer type and by product. As noted in the segment footnote, the Company’s business consists of one reporting segment. A reconciliation of revenue by geographical region, customer type and product are provided in Note 12 of our Consolidated Financial Statements.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Summary of Significant Accounting Policies (Policies)	6 Months Ended
Summary of Significant Accounting Policies (Policies)	Jun. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Consolidated Financial Statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the Consolidated Financial Statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of the results for the interim periods presented. The information included in this quarterly report on Form 10-Q should be read in conjunction with the audited Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year-ended December 31, 2023 filed with the SEC on February 22, 2024 and the Australian Securities Exchange ("ASX") on February 23, 2024 (the “2023 Annual Report"). Except for revenue recognition, related to the RECELL GO system, as described below, there have been no changes to the Company’s significant accounting policies as described in the 2023 Annual Report that have had a material impact on the Company’s Consolidated Financial Statements. See the summary of the Company’s significant accounting policies set forth in the notes to its Consolidated Financial Statements included in the 2023 Annual Report.
Principles of Consolidation	Principles of Consolidation The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly reviewed by the Chief Operating Decision Maker ("CODM") and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The ASU also allows, in addition to the measure that is most consistent with GAAP, the disclosure of additional measures of segment profit or loss that are used by the CODM in assessing segment performance and deciding how to allocate resources. All disclosure requirements under ASU 2023-07 are also required for public entities with a single reportable segment. The ASU is effective for the Company’s 2023 Annual Report on Form 10-K for the fiscal year ending December 31, 2025, and subsequent interim periods, with early adoption permitted. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments affected by this ASU require (i) enhanced disclosures in connection with an entity's effective tax rate reconciliation and (ii) income taxes paid disaggregated by jurisdiction. These amendments are effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.
Use of Estimates	Use of Estimates The preparation of the accompanying Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts (including estimate of the average selling price for PermeaDerm sales, stand-alone selling price ("SSP") for the RPD, allowance for credit losses, reserves for inventory excess and obsolescence, carrying value of long-lived assets, the useful lives of long-lived assets, accounting for marketable securities, income taxes, fair value of debt, fair value of warrants and stock-based compensation) and related disclosures. Estimates have been prepared based on the current and available information. However, actual results could differ from estimated amounts.
Foreign Currency Translation and Foreign Currency Transactions	Foreign Currency Translation and Foreign Currency Transactions The financial position and results of operations of the Company’s operating non-U.S. subsidiaries are generally determined using the respective local currency as the functional currency of that subsidiary. Assets and liabilities of these subsidiaries are translated at the exchange rate in effect at each period end. Income statement accounts are translated at the average rate of exchange prevailing during the period. Adjustments arising from the use of differing exchange rates from period to period are included in Other comprehensive gain (loss) in Stockholders’ Equity. The Company’s non-operating subsidiaries that use the U.S. dollar as their functional currency remeasure monetary assets and liabilities at exchange rates in effect at the end of each period and nonmonetary assets and liabilities at historical rates. Gains and losses resulting from these remeasurements are included in earnings in the Consolidated Statement of Operations. Gains and losses for remeasurement were minimal during the three-months and six-months ended June 30, 2024 and 2023. The Company records certain revenues and operating expenses in foreign currencies. These revenues and expenses are translated into U.S. Dollars based on the average exchange rate for the reporting period. Assets and liabilities denominated in foreign currencies are translated into U.S. Dollars at the exchange rate in effect as of the balance sheet date. For the three and six-months ended June 30, 2024, the Company incurred approximately $7,000 and $12,000 in losses included in net loss in the Consolidated Statement of Operations, respectively. For the three and six-months ended June 30, 2023 transactions gains and losses were minimal.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash held at deposit institutions and cash equivalents. Cash equivalents consist primarily of money market funds. Cash equivalents also include short-term highly liquid investments with original maturities of three months or less from the date of purchase. The Company holds cash at deposit institutions in the amount of $6.6 million and $10.7 million as of June 30, 2024 and December 31, 2023, respectively. The Company does not have cash on deposit denominated in foreign currency in foreign institutions as of June 30, 2024. As of December 31, 2023, the Company had $69,000 of cash on deposit denominated in foreign currencies in foreign institutions. As of June 30, 2024 and December 31, 2023, the Company held cash equivalents in the amount of $10.8 million and $11.4 million, respectively.
Concentrations	Concentrations Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, trade receivables and debt and other liabilities. As of June 30, 2024 and December 31, 2023, substantially all the Company’s cash was deposited in accounts at financial institutions, and amounts exceed federally insured limits and are subject to the risk of bank failure. As of June 30, 2024 and December 31, 2023, no single commercial customer accounted for more than 10% of net accounts receivable or more than 10% of revenues for the three-months and six-months ended June 30, 2024 and 2023.
Revenue Recognition	Revenue Recognition The Company generates revenues primarily from the sale of: • RECELL EOU, RPK, and PermeaDerm products to hospitals, other treatment centers, and distributors. • Maintenance fee received from BARDA to ensure first right of access to our inventory. In the prior year, the Company recorded service revenue for the emergency preparedness services provided to BARDA. • Lease revenue for the RPD. The Company’s sale of the RECELL EOU and PermeaDerm products are accounted for under ASC 606, Revenue from contracts with customers (“ASC 606”). Revenue for the RECELL GO system is disaggregated between two accounting standards: (1) ASC 606 for the RPK and (2) ASC 842, Leases ("ASC 842") for the RPD. Revenues from BARDA, are accounted for under ASC 606, and are included in Sales revenues within the Consolidated Statements of Operations. To determine revenue recognition for contracts that are within the scope of ASC 606, the Company performs the following five steps: 1. Identify the contract with a customer 2. Identify the performance obligations 3. Determine the transaction price 4. Allocate the transaction price to the performance obligations 5. Recognize revenue when/as a performance obligation(s) is(are) satisfied In order for an arrangement to be considered a contract, it must be probable that the Company will collect the consideration to which it is entitled for goods or services to be transferred. The Company then assesses the goods or services promised within the contract to determine whether each promised good or service is a performance obligation. Performance obligations are promises in a contract to transfer a distinct good or service to the customer that (i) the customer can benefit from on its own or together with other readily available resources, and (ii) is separately identifiable from other promises in the contract. The Company determines the transaction price based on the amount of consideration the Company expects to receive for transferring the promised goods or services in the contract. Consideration may be fixed, variable, or a combination of both. At contract inception for arrangements that include variable consideration, the Company estimates the probability and extent of consideration it expects to receive under the contract utilizing either the most likely amount method or expected amount method, whichever best estimates the amount expected to be received. The Company then considers any constraints on the variable consideration and includes in the transaction price variable consideration to the extent it is deemed probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. When accounting for a contract that contains multiple performance obligations, the Company must develop judgmental assumptions to determine the estimated SSP for each performance obligation identified in the contract. We utilize the observable SSP when available, which represents the price charged for the promised product or service when sold separately. When the SSP for our products or services are not directly observable, we determine the SSP using relevant information available and apply suitable estimation methods including, but not limited to, the cost-plus margin approach. The Company then allocates the transaction price to each performance obligation based on the relative SSP and recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) control is transferred to the customer and the performance obligation is satisfied. Most of the Company’s contracts have a single performance obligation. As such, the Company recognizes revenue when its customers obtain control of promised goods or services, in an amount that reflects the consideration which the Company expects to be entitled in exchange for those goods or services. Revenue is recognized net of volume discounts (variable consideration). For the Company’s contracts that have an original duration of one year or less, the Company elected the practical expedient applicable to such contracts and does not consider the time value of money. Further, because of the short duration of these contracts, the Company has not disclosed the transaction price for the remaining performance obligations as of each reporting period or when the Company expects to recognize this revenue. The Company has further applied the practical expedient to exclude sales tax in the transaction price and expense contract acquisition costs such as commissions and shipping and handling expenses as incurred. Revenue recognition for contracts that are within the scope of ASC 606 and ASC 842 The Company enters into contracts with customers where it receives consideration for the RPK and does not receive additional consideration for the RPD. As a result, judgment and analysis are required to determine the appropriate accounting, including: (i) whether the arrangement contains an embedded lease, and if so, whether such embedded lease is a sales-type lease or an operating lease, (ii) the amount of the total consideration, as well as variable consideration, (iii) the identification of the distinct performance obligations contained within the arrangement, (iv) how the arrangement consideration should be allocated to each performance obligation when multiple performance obligations exist, including the determination of standalone selling price, and (v) when to recognize revenue on the performance obligations. For these contracts the Company considers the guidance under ASC 842 to determine if furnishing the RPD to the customer during the period of use establishes an embedded lease. To determine if the contract contains a lease, the Company evaluates the customer’s rights and ability to control the use of the underlying equipment throughout the contract term, including any equipment substitution rights retained by the Company. As the contract conveys the right to control the use of an identified asset for a period of time, the contract was determined to contain a lease. The Company then evaluated the lease classification based on the below: • Pursuant to ASC 842-30, the Company will classify a lease as a sales-type lease if: (i) the lease transfers ownership of the underlying asset to the lessee by the end of the lease term, (ii) the lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise, (iii) the lease term is for the major part of the remaining economic life of the underlying asset, (iv) the present value of the sum of the lease payments and any residual value guaranteed by the lessee that is not already reflected in the lease payments equals or exceeds substantially all (90% or more) of the fair value of the underlying asset, or (v) the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. • Pursuant to ASC 842-30, when none of the sales-type lease classification criteria are met, a lessor would classify the lease as a direct financing lease when both of the following criteria are met: (i) the present value of the sum of the lease payments and any residual value guaranteed by the lessee that is not already reflected in the lease payments and/or any other third party unrelated to the lessor equals or exceeds substantially all (90% or more) of the fair value of the underlying asset and (ii) it is probable that the lessor will collect the lease payments plus any amount necessary to satisfy a residual value guarantee. • Pursuant to ASC 842-30, a lessor would classify a lease as an operating lease when none of the sales-type or direct financing lease classification criteria are met. Further, per ASC 842, a lessor is required to classify a lease with variable lease payments that do not depend on an index or rate as an operating lease at lease commencement if the lease would have been classified as a sales-type lease or a direct financing lease in accordance with the classification criteria of ASC 842 and the lessor would have otherwise recognized a loss at inception. In determining whether the lease components are related to a sales-type lease or an operating lease, the Company evaluates if the lease transfers ownership at the end of the lease term, purchase options, the lease term in relation to the economic life of the asset, if the lease payments exceed the fair value of the asset, and if the asset is of a specialized nature. The Company also evaluates if the lease results in a loss at inception. As the lease term is for the major part of the economic life, the lease meets the classification criteria for sales-type lease. However, to determine if the contract results in a loss at lease inception we evaluated the consideration in the contract. The consideration at lease commencement does not contain fixed payments, purchase options, penalty payments or residual value guarantees. The variable consideration is related to the sale of the RPK. As the variable lease payments are not dependent on an index or rate, the variable consideration is excluded from consideration at contract inception resulting in a loss at lease commencement. As such, the Company classifies the lease as an operating lease. The contracts contain a lease component, the RPD, and a nonlease component, the RPK. The lease component will be accounted for under the ASC 842 and the nonlease component will be accounted for under ASC 606, as described above. In accordance with ASC 842, the consideration in the contract will be allocated to each separate lease component and nonlease component of the contract. The consideration is allocated to these lease and non-lease components based on the SSP (as described above for contracts with-in the scope of ASC 606). In accordance with ASC 842, variable consideration will be recognized once the sale of the RPK occurs. Consideration will be allocated to the RPD and RPK based on the SSP. Consideration related to the RPD will be recognized as Lease revenue and consideration related to the RPK will be recognized as Sales revenues in accordance with guidance in ASC 606, as described above, upon transfer of control of the product. Assets in our lease program are reported in Plant and equipment, net on our Consolidated Balance Sheets and are depreciated over the useful life of the RPD devices 200 uses, as indicated in the Instructions for Use that were approved by the FDA, and expensed as Costs of goods sold in the Consolidated Statements of Operations. The RPD depreciation has a direct relationship to the number of RPK units sold. Based on customer usage, each purchase of an RPK unit results in a 1/200 depreciation to the RPD.

The Company’s basic net loss per share is calculated by dividing the net loss by the weighted-average number of shares of common stock outstanding for the relevant period. In accordance with ASC 710-10, Compensation - General, 93,845 shares of Common Stock held by the rabbi trust are excluded from the denominator in the basic and diluted net loss per common share calculations. For details on shares of common stock held by the rabbi trust refer to Note 18 of our Consolidated Financial Statements. For the purposes of the calculation of diluted net loss per share, options to purchase common stock, restricted stock units and unvested shares of common stock issued upon the early exercise of stock options have been excluded from the calculation of diluted net loss per share as their effect is anti-dilutive. Because the Company has reported a net loss for the three-months and six-months ended June 30, 2024 and 2023, diluted net loss per common share is the same as the basic net loss per share for those periods.

Long-term Debt

6. Long-term debt

On October 18, 2023 (the “Closing Date”) the Company entered into a credit agreement, by and between the Company, as borrower, and an affiliate of OrbiMed Advisors, LLC (the “Lender”) as the lender and administrative agent (the "Credit Agreement") . The Credit Agreement provides for a five-year senior secured credit facility in an aggregate principal amount of up to $90.0 million, of which (i) $40.0 million was made available on the Closing Date (the “Initial Commitment Amount”), (ii) $25.0 million is available, at the Company’s discretion, on or prior to December 31, 2024, subject to certain net revenue requirements, and (iii) $25.0 million is available, at the Company’s discretion, on or prior to June 30, 2025, subject to certain net revenue requirements. The maturity date of the agreement is October 18, 2028 (the "Maturity Date"). On the Closing Date, the Company closed on the Initial Commitment Amount of $40.0 million, less certain fees and expenses payable to or on behalf of the Lender. The Company received net proceeds of $38.8 million upon closing after deducting the Lender's transaction costs in connection with the issuance.

All obligations under the Credit Agreement are guaranteed by all of the Company’s wholly owned subsidiaries (subject to certain exceptions) and secured by substantially all of the Company's and each guarantor's assets. The loan will be due in full on the Maturity Date unless the Company elects to repay the principal amount at any time prior to the Maturity Date. Upon prepayment, the Company will owe the applicable repayment premium and exit fee of 3% on the principal amount of the loans. The repayment premium varies between 0.0% - 3.0%, depending on certain conditions that are defined in the Credit Agreement. The repayment premium incorporates the make-whole amount. The make-whole amount represents the remaining scheduled interest payments on the loan during the period commencing on the prepayment date through the 24-month anniversary of the Closing Date. The Credit Agreement further states that the Company will be required to repay the principal amount of the loans if the Company does not achieve certain net revenue thresholds. If, for any quarter until the maturity date, the Company’s net revenue does not equal or exceed the applicable trailing 12-month amount as set forth in the Credit Agreement, then the Company shall repay in equal quarterly installments equal to 5.0% of the outstanding principal amount of the loan on the date the net revenue amount was not satisfied, together with a repayment premium and exit fee. The Company shall repay amounts outstanding in full immediately upon an acceleration as a result of an event of default as set forth in the Credit Agreement, together with a repayment premium and other fees. As of June 30, 2024, the Company has not made any repayments on the outstanding debt balance.

During the term of the Credit Agreement, interest payable in cash by the Company shall accrue on any outstanding debt at a rate per annum equal to the greater of (x) the SOFR rate for such period and (y) 4.00% plus, in either case, 8.00%. As of June 30, 2024, the interest rate was 13.33%. During an event of default, any outstanding amount will bear interest at a rate of 4.00% in excess of the otherwise applicable rate of interest. The Company will pay certain fees with respect to the Credit Agreement, including an upfront fee, an unused fee on the undrawn portion of the Loan Facility, an administration fee, a repayment premium and an exit fee, as well as certain other fees and expenses of the Lender. The undrawn fee accrues at 0.5% of the undrawn balance and it is recorded as an asset in the Consolidated Balance Sheets.

The Credit Agreement contains certain customary events of default, including with respect to nonpayment of principal, interest, fees or other amounts; material inaccuracy of a representation or warranty; failure to perform or observe covenants; material defaults on other indebtedness; bankruptcy and insolvency events; material monetary judgments; loss of certain key permits, persons and contracts; material adverse effects; certain regulatory matters; and any change of control. As of June 30, 2024, the Company was in compliance with all financial covenants in the Credit Agreement.

Each of the Credit Agreement and the Pledge and Security Agreement entered into by the Company, the guarantors and the Lender on October 18, 2023 (the “Pledge and Security Agreement”) contains a number of customary representations, warranties and covenants that, among other things, will limit or restrict the ability of the Company and its subsidiaries to (subject to certain qualifications and exceptions): create liens and encumbrances; incur additional indebtedness; merge, dissolve, liquidate or consolidate; make acquisitions, investments, advances or loans; dispose of or transfer assets; pay dividends or make other payments in respect of their

capital stock; amend certain material documents; redeem or repurchase certain debt; engage in certain transactions with affiliates; and enter into certain restrictive agreements. In addition, the Company and guarantors will be required to maintain at least $10.0 million of unrestricted cash and cash equivalents.

On the Closing Date, the Company issued to an affiliate of the Lender a warrant (the “Warrant”) to purchase up to 409,661 shares of the Company’s Common Stock, par value $0.0001 per share (“Common Stock”), at an exercise price of $10.9847 per share, with a term of 10 years from the issuance date. The Warrant contains customary share adjustment provisions, as well as weighted average price protection in certain circumstances.

As permitted under ASC 825, Financial Instruments, the Company elected the fair value option to record the long-term debt and warrant with changes in fair value recorded in the Consolidated Statements of Operations in Other income, net. Changes related to instrument-specific credit risk are revalued by comparing the amount of the total change in fair value of the long-term debt to the amount of change in fair value that would have occurred if the Company’s credit spread had not changed between the reporting periods, and is recorded in other comprehensive income in the Consolidated Balance Sheet. The difference between the fair value of the long-term debt and the unpaid principal balance of $40.0 million is an additional liability of $989,000 and reduction to the liability of $188,000 as of June 30, 2024 and December 31, 2023, respectively. For changes in fair value refer to Note 4 of our Consolidated Financial Statements.

Fair Value Disclosures [Abstract]

Fair Value Measurements

4. Fair Value Measurements

ASC 820, Fair Value Measurement, the authoritative guidance on fair value measurements establishes a framework with respect to measuring assets and liabilities at fair value on a recurring basis and non-recurring basis. Under the framework, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, as of the measurement date. The framework also establishes a three-tier hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the

most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability and are developed based on the best information available in the circumstances. The hierarchy consists of the following three levels:

Level 1: Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.

Level 2: Inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3: Inputs are unobservable inputs for the asset or liability

The following tables present information about the Company’s financial assets measured at fair value on a recurring basis, based on the three-tier fair value hierarchy:

The following table presents the summary of changes in the fair value of our Level 3 financial instruments:


	As of June 30, 2024						As of December 31, 2023
	Long-term debt			Warrant liability			Long-term debt		Warrant liability
Balance beginning of period	$	39,812		$	3,158		$	-	$	-
Fair value on issuance date								37,575		2,425
Change in fair value in earnings		1,615			(1,190	)		1,616		733
Change in fair value in other comprehensive loss		(438	)		-			621		-
Balance end of period, at fair value	$	40,989		$	1,968		$	39,812	$	3,158

The Company’s Level 1 assets include money market instruments and are valued based upon observable market prices. Level 2 assets consist of U.S Treasury securities and U.S. Government Agency obligations. Level 2 securities are valued based upon observable inputs that include reported trades, broker/dealer quotes, bids and offers. The corporate-owned life insurance contracts are recorded at cash surrender value, which approximates the fair value and is categorized as Level 2. Non-qualified deferred compensation plan liability is measured at fair value based on quoted prices of identical instruments to the investment vehicles selected by the participants and it is recorded as Level 2. There were no transfers between fair value measurement levels during the periods ended June 30, 2024 and December 31, 2023.

Long-term debt

The fair value of the debt was determined using a Monte Carlo Simulation ("MCS") in order to predict the probability of different outcomes. The valuation was performed based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The fair value of the debt is recorded in the Consolidated Balance Sheets. The fair value is estimated by the Company each reporting period and the change in the fair value is recorded in both earnings and other comprehensive income depending on the instrument's inherent credit risk and market risk related to the debt valuation.

As the debt is subject to net revenue requirements, the valuation of the debt was determined using MCS. The underlying metric to be simulated is the projected Trailing Twelve Month (“TTM”) revenues at each quarter end through the maturity date of October 18. 2028. Based on the simulated metric, the different levels of simulated TTM revenues may trigger different discounted cash flow scenarios in which the TTM revenues are lower than the targeted revenues per the Credit Agreement or the TTM revenues are equal to or higher than the targeted revenues per the Credit Agreement. The MCS performs 100,000 iterations of various simulated revenues to determine the fair value of the debt.

The below assumptions were used in the Monte Carlo simulation


	June 30, 2024			December 31, 2023
Risk-free interest rate		4.34	%		3.81	%
Revenue volatility		64.00	%		64.00	%
Revenue discount rate		17.11	%		16.58	%

Warrant Liability

The fair value of the warrant liability is recognized in connection with the Credit Agreement. The fair value of the warrant liability was determined based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The fair value of the warrant liability, which is reported within Warrant liability on the Consolidated Balance Sheets, is estimated by the Company based on the Black-Scholes option pricing model with the following key inputs:


	June 30, 2024			December 31, 2023
Price of common stock	$	7.92		$	13.72
Expected term	9.31 years			9.81 years
Expected volatility		54.21	%		31.07	%
Exercise price	$	10.9847		$	10.9847
Risk-free interest rate		4.31	%		3.84	%
Expected dividends		0.00	%		0.00	%

The Internal Revenue Code of 1986, as amended, allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) Plan. The Company matches contributions to the 401(k) Plan based on the amount of salary deferral contributions the participant makes to the 401(k) Plan. The Company will match up to 6% of an employee’s compensation that the employee contributes to his or her 401(k) Plan account up to the maximum allowable. The Company's total matching contributions to the 401(k) Plan were $518,000 and $249,000 for the three-months ended June 30, 2024 and 2023, respectively, and $1.4 million and $671,000 for the six-months ended June 30, 2024 and 2023, respectively.

Non-Qualified Deferred Compensation Plan

The Company’s NQDC plan, which became effective in October 2021 allows for eligible management and highly compensated key employees to elect to defer a portion of their salary, bonus, commissions and RSU awards to later years. Cash deferrals are immediately vested and are subject to investment risk and a risk of forfeiture under certain circumstances. RSU deferrals are subject to the vesting conditions of the award. Once RSUs vest, subject to a six-month and one day holding period, employees are allowed to diversify the common stock into other investment options offered by the plan. For cash deferrals, the Company matches 4% to 6% (depending on level) of employee contributions. These matching employer contributions are vested over a two-year period with 25% vesting on year one and 75% vesting on year two for employees under 55 years of age. Employer contributions for employees over 55 years of age are immediately vested. Employer contributions to the NQDC Plan were $33,000 and $39,000 for the three-months ended June 30, 2024 and 2023, respectively and $67,000 and $80,000 for the six-months ended June 30, 2024 and 2023, respectively. The Company’s deferred compensation plan liability was $3.9 million and $3.8 million as of June 30, 2024 and December 31, 2023, respectively. These liabilities are split between current and long term on the Consolidated Balance Sheets. As of June 30, 2024, $753,000 is included in Current non-qualified deferred compensation liability and $3.1 million in the long term non-qualified deferred compensation liability. As of December 31, 2023, $168,000 is included in Current non-qualified deferred compensation liability and $3.7 million in the long-term non-qualified deferred compensation liability. During the three-months ended June 30, 2024, the Company did not have distributions from the deferred compensation liability. For the six-months ended June 30, 2024, the Company had distributions of approximately $215,000 in the deferred compensation liability for terminated employees.

During the three-months and six-months ended June 30, 2023, the Company had a distribution of approximately $82,000 for a terminated employee.

The Company established a COLI to fund the NQDC Plan. Amounts in the COLI are invested across a number of funds. The securities are carried at the cash surrender value on the Consolidated Balance Sheets. The Company records investment gains and losses of the COLI as Other income net. Refer to Note 4 of our Consolidated Financial Statements for the fair values of the COLI policies and the NQDC liability.

Rabbi Trust

During April 2022, the Company established a rabbi trust to hold the assets of the NQDC Plan. The rabbi trust holds the COLI asset and the Common stock from deferred RSU awards that have vested. The NQDC Plan permits diversification of fully vested shares into other equity securities subject to a six-month and one day holding period. In accordance with ASR 268, Redeemable Preferred Stock, and ASC 718, Compensation — Stock Compensation, prior to vesting, the deferred share awards are classified as an equity instrument and changes in fair value of the amount owed to the participant are not recognized. The redemption amounts of the deferred awards are based on the vested percentage and are recorded outside of permanent equity as Non-qualified deferred compensation share awards on the Consolidated Balance Sheets. As of June 30, 2024 and December 31, 2023, a total of 101,526 and 81,052, shares awards have been deferred, respectively. Vested shares are converted to Common stock and are reclassified to permanent equity. Common stock held in the rabbi trust is classified in a manner similar to treasury stock and presented separately on the Consolidated Balance Sheets as Common stock held by the NQDC Plan. As of June 30, 2024 and December 31, 2023 a total of 93,845 and 99,106 shares were held in the rabbi trust at the redemption value of $1.0 million and $1.1 million, respectively.

The following table summarizes the Non-qualified deferred compensation plan share award activity as of June 30, 2024 and December 31, 2023 (in thousands):

(in thousands)	June 30, 2024			December 31, 2023

The Company

1. The Company

Nature of the Business

AVITA Medical, Inc. (collectively with its subsidiaries, “AVITA Medical”, “we”, “our”, “us”, or “Company”) is a commercial-stage regenerative medicine company transforming the standard of care in wound management and skin restoration with innovative devices. At the forefront of the Company's portfolio is its patented and proprietary RECELL® technology (“RECELL”). RECELL harnesses the regenerative properties of a patient’s own skin to create an autologous skin cell suspension, Spray-On Skin™ Cells, delivering a transformative solution at the point of care. This breakthrough technology serves as the catalyst for a new treatment paradigm enabling improved clinical outcomes. The Company also holds the right to market, sell, and distribute PermeaDerm®, a biosynthetic wound matrix, in the United States under the terms of an exclusive multi-year distribution agreement with Stedical Scientific, Inc. ("Stedical").

The single-use RECELL Autologous Cell Harvesting Device ("RECELL Ease-of-Use" or "RECELL EOU") is approved by the U.S. Food and Drug Administration ("FDA") for the treatment of thermal burn wounds and full-thickness skin defects, and repigmentation of stable depigmented vitiligo lesions. The Company's next-generation device, RECELL GO™ Autologous Cell Harvesting Device ("RECELL GO"), is FDA-approved to treat thermal burn wounds and full-thickness skin defects. RECELL GO introduces enhanced features that streamline the preparation of Spray-On Skin Cells and improves workflow efficiency in the operating room. It consists of two components: a multi-use, AC-powered RECELL GO Processing Device ("RPD") and a RECELL GO Preparation Kit ("RPK"). The RPK contains the single-use RECELL GO Cartridge, disaggregation head, RECELL Enzyme™, and other components. The RPD provides the control for the RPK, manages the pressure applied to disaggregate the donor skin cells, and precisely regulates the incubation times of the RECELL Enzyme and solutions to optimize cell yield and promote cell viability.
