Share-Based Payment Plans

15. Share-Based Payment Plans

Overview of Employee Share-Based Compensation Plans

Our former parent company, AVITA Medical, adopted the Employee Share Plan and the Incentive Option Plan (collectively, the “2016 Plans”). Upon completion of the Redomiciliation, the 2016 Plans were terminated with respect to future grants and accordingly, there are no more shares available to be issued under the 2016 Plans. In addition, upon completion of the Redomiciliation, the Company had an implicit consolidation or reverse stock split of 100:1 and all share information presented below in relation to the 2016 Plans has been presented on a reverse split stock basis. During November 2020, the Company, pursuant to Rule 416 under the Securities Act of 1933, filed a registration statement on form S-8 to register a total of 1,750,000 shares of common stock which may be issued pursuant to the terms of the Company’s 2020 Omnibus Incentive Plan (“2020 Plan”). On December 22, 2021, the Company’s stockholders approved the issuance of options and awards to the Board of Directors and the CEO. These awards are subject to the vesting and performance conditions as denoted in the individual agreements.

The 2020 Plan provides for the grant of the following Grants: (a) Incentive Stock Options, (b) Nonstatutory Stock Options, (c) Stock Appreciation Rights, (d) Restricted Stock Grants, (e) Restricted Stock Unit Grants, (f) Performance Grants, and (g) Other Grants. The 2020 Plan will be administered by the Compensation Committee or by the Board acting as the Compensation Committee. Subject to the general purposes, terms and conditions of the 2020 Plan, applicable law and any charter adopted by the Board governing the actions of the Compensation Committee, the Compensation Committee will have full power to implement and carry out the 2020 Plan. Without limitation, the Compensation Committee will have the authority to, interpret the plan, approve persons to

receive grants, determine the terms and number of shares of the grants, determine vesting and exercisability of grants, and make all other determinations necessary or advisable in connection with the administration of this Plan.

The contractual term of awards granted under the 2020 Plan is ten years from the date of its grant. Unless otherwise specified, the vesting period of awards under the 2020 Plan was: (i) vest over a four year period in four equal installments, 25% at the end of each year from the date of grant, and /or (ii) subject to other performance criteria and hurdles, as determined by the Compensation Committee.

Share-Based Payment Expenses

Share-based payment transactions are recognized as compensation expense based on the fair value of the instrument on the date of grant. The Company uses the graded-vesting method to recognize compensation expense. Compensation cost is reduced for forfeitures as they occur in accordance with ASU 2016-09, Simplifying the Accounting for Share-Based Payments ("ASU 2016-09"). During the three months ended March 31, 2022 and 2021, the Company recorded share-based compensation expense of $2.9 million, and $1.3 million, respectively. No income tax benefit was recognized in the consolidated statement of operations for share-based payment arrangements for the three months ended March 31, 2022 and 2021.

The Company has included share-based compensation expense as part of operating expenses in the accompanying consolidated statements of operations as follows (in thousands):

	Three-months ended March 31,

Restricted Stock Units

Restricted stock units (“RSUs”) are granted to executives as part of their long-term incentive compensation. RSUs granted prior to the 2020 Plan arise out of contracts between the Company's former parent company, AVITA Medical and the holders of such securities. RSUs granted as a result of stockholder approval at the December 22, 2021 AGM arise out of contracts between the Company and the holders of such securities. These RSU awards were approved by the Compensation Committee as determined necessary. All RSU awards have a contractual term of 10 years and vest in accordance with the tenure or performance conditions as determined by the Compensation Committee and set out in the contracts between the Company and the holders of such securities. The grant date fair value is determined based on the price of the Company stock price on the date of grant (stock price determined on NASDAQ post Redomiciliation and ASX prior to the Redomiciliation). RSUs primarily consist of awards to the CEO and other executives as well as Non-Executive Directors (as occurred following the 2021 AGM). The CEO RSU awards are described below.

37,620 (23,820 RSUs and 13,800 options) - Achieve a market capitalization of the Company of greater than or equal to US$1.25 billion (as compared to market capitalization of ~US$435M as of October 14, 2021) and maintain that market capitalization for at least 30 consecutive calendar days on or before December 31, 2024.

In order for any options or RSUs issued to the CEO to vest, both the service condition and the relevant performance or market condition (as set out in the relevant agreement between the Company and the CEO) must be satisfied.

Retirement Plans

18. Retirement Plans

The Company offers a 401(k)-retirement savings plan (the “401(k) Plan”) for its employees, including its executive officers, who satisfy certain eligibility requirements. 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. Total Company matching contributions to the 401(k) Plan were $233,000 and $221,000 in the three months ended March 31, 2022 and 2021, respectively.

Deferred compensation plans

The Company’s Deferred Compensation Plan (the "DCP"), which became effective on 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. These deferrals are immediately vested and are subject to investment risk and a risk of forfeiture under certain circumstances. 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 old. For employees over 55 years old employer contributions are immediately vested. Employer contributions to the DCP were $84,000 and $0 for the three months ended March 31, 2022 and 2021. The Company’s deferred compensation plan liability was $571,000 and $262,000 as of March 31, 2022 and December 31, 2021, respectively, and is included in other long-term liabilities.

The Company established a COLI to fund the DCP. The COLI is subject to creditor claims in the event of insolvency, but the assets held in the COLI are not available for general corporate purposes. Amounts in the COLI are invested in a number of funds. The securities are carried at the cash surrender value and are included in other long-term assets on the Consolidated Balance Sheets. We record investment gains and losses in operating expenses on the Consolidated Statements of Operations, along with the offsetting amount related to the increase or decrease in deferred compensation liability.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2022

Accounting Policies [Abstract]

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 of America (“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. 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 Transition Report on Form 10-KT for the transition period ended December 31, 2021 filed with the SEC on February 28, 2022 (United States) and the ASX on March 01, 2022 (Australia) (the “Transition Report”).

There have been no changes to the Company’s significant accounting policies as described in the Transition Report on Form 10-KT 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 Transition 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 on consolidation.

Use of Estimates

The preparation of the accompanying consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts (including doubtful accounts, carrying value of long-lived asset, the useful lives of long-lived assets, accounting for marketable securities, income taxes, stock-based compensation, and the stand-alone selling price for the BARDA contract) and related disclosures. Estimates have been prepared on the basis of 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 accumulated other comprehensive gain (loss) in shareholders’ equity. Gains and losses resulting from foreign currency transactions are included in general and administrative expenses and were a loss of $22,000 and gain of $8,000 for the three months ended March 31, 2022 and 2021, respectively.

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 and foreign currency transactions are included in general and administrative expenses. During the three months ended March 31, 2022 and 2021, the Company recorded losses of $15,000 and $16,000, respectively.

Comprehensive Income (Loss)

The components of comprehensive income (loss) consist of net income (loss), foreign currency translation adjustments from its subsidiaries not using the U.S. dollar as their functional currency and unrealized gains and losses in investments available for sale. The Company did not have reclassifications from other comprehensive income (loss) to net loss during the quarter ended March 31, 2022.

Revenue Recognition

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.

To determine revenue recognition for arrangements that are within the scope of Accounting Standard Codification (“ASC”) Topic 606, Revenue Recognition, 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 performance obligation(s) 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. Once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised with each contract, determines whether those are performance obligations and the related transaction price. The Company then recognizes the sale of goods based on the transaction price that is allocated to the respective performance obligation when the performance obligation is satisfied.

The Company’s revenue consists primarily of the sale of the RECELL System to hospitals or other treatment centers and to BARDA (collectively, “customers”), predominately in the United States. The Company evaluated the BARDA contract and concluded that a portion of the arrangement, such as the procurement of the RECELL system and the emergency preparedness, represents a transaction with a customer and as such are in the scope of ASC 606. Amounts received from BARDA for the research and development of the Company’s product are classified as BARDA income in the consolidated statement of operations and are accounted for under IAS 20. For further details refer to BARDA Income and Receivables below.

Revenues for commercial customers (hospitals and treatment centers) are recognized as control of the product is transferred to customers, at an amount that reflects the consideration expected to be received in exchange for the product. Revenues are recognized net of volume discounts. As such, revenue is recognized only to the extent a significant reversal of revenues is not expected to occur in subsequent periods. 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 fulfilment costs such as commissions and shipping and handling expenses as incurred.

For revenues related to the BARDA contract within the scope of ASC 606, the Company identified two performance obligations (i) the procurement of 5,614 RECELL units, (ii) emergency preparedness services. Through this contract the Company promises to procure the product through a vendor management inventory arrangement and to stand ready to provide emergency deployment services related to the product. Emergency preparedness services include procuring necessary storage containers, housing, and maintaining the containers (and product), and providing shipping and handling services in the event of an emergency situation. This stand ready obligation is a series of distinct services that are substantially the same and have the same pattern of transfer to the customer, overtime as services are consumed.

The total transaction price for the portion of the BARDA contract that is within the scope of ASC 606, was determined to be $9.2 million. The transaction price was allocated on a stand-alone selling price basis as follows: $7.6 million to the procurement of the RECELL product, which is classified as revenues when recognized in the consolidated statement of operations and $1.6 million to the emergency deployment services which is classified as revenues when recognized in the consolidated statement of operations. The $1.6 million for emergency deployment includes variable consideration which is deemed immaterial to the contract as a whole. The Company estimated the stand-alone selling price of the procurement of the RECELL product based on historical pricing of the Company’s product at the initial execution of the contract. The Company estimated the stand-alone selling price of the emergency deployment services performed based on the Company’s projected cost of providing the services plus an applicable profit margin as denoted in the contract.

The Company’s performance obligations are either satisfied at a point in time or over time as services are provided. The product procurement performance obligation is satisfied at a point in time, upon transfer of control of the product. As such, the related revenue for these performance obligations is recognized at a point in time as revenue within the Company’s consolidated statement of operations. In addition to guidance under ASC 606, the Company recognizes revenue from the sales of RECELL product to BARDA for placement into vaccine stockpiles in accordance with Securities and Exchange Commission (SEC) Interpretation, Commission Guidance regarding Accounting for Sale of Vaccines and BioTerror Countermeasures to the Federal Government for Placement into the Pediatric Vaccine Stockpile or the Strategic National Stockpile (SNS). Under this guidance, revenue is recognized when product is placed in the BARDA vendor-managed inventory as control of the product has been transferred to the customer at the time of delivery to the VMI. RECELL units that have been delivered to BARDA have a product replacement obligation at no cost to BARDA due to product’s limited shelf-life. The estimated cost of the expired inventory over the term of the contract is recognized on a per unit basis at the time of delivery. The liability is released upon replacement of the product along with a corresponding reduction to inventory. The emergency preparedness services performance obligation is satisfied over time. Revenue for the emergency deployment will be recognized on a straight-line basis during the term of the contract as services are consumed over time. Services recognized are included in sales within the consolidated statement of operations. Contract costs to fulfil the performance obligations are incremental and expected to be recovered are capitalized and amortized on a straight-line basis over the term of the contract. Contract costs are included in other long-term assets.

Contract Liabilities

The Company receives payments from customers based on contractual terms. Trade receivables are recorded when the right to consideration becomes unconditional. The Company satisfies its performance obligation on product sales when the products are shipped or delivered, depending on the terms of the sale. Payment terms on invoiced amounts are typically 30-90 days, and do not include a financing component. Contract liabilities are recorded when the Company receives payment prior to satisfying its obligation to transfer goods to a customer.

Cost of Sales

Cost of sales related to products includes costs to manufacture or purchase, package, and ship the Company’s products. Costs also include relevant production overhead and depreciation and amortization. These costs are recognized when control of the product is transferred to the customer and revenue is recognized.

Income Taxes

Income taxes are accounted for using the liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income or loss in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that a portion of the deferred tax asset will not be realized. We recognize interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying consolidated statement of operations. Accrued interest and penalties are included on the related tax liability line in the consolidated balance sheet.

The Company reviews its uncertain tax positions regularly. An uncertain tax position represents the Company’s expected treatment of a tax position taken in a filed return or planned to be taken in a future tax return or claim that has not been reflected in measuring income tax expense for financial reporting purposes. The Company recognizes the tax benefit from an uncertain tax position when it is more-likely-than-not that the position will be sustained upon examination on the basis of the technical merits or the statute of limitations for the relevant taxing authority to examine and challenge the tax position has expired.

Cash and Cash Equivalents

Consists of cash held at deposit institutions and cash equivalents. Cash equivalents consist of short-term highly liquid investments with original maturities of three months or less from the date of purchase and consist primarily of money market funds. The Company holds cash at deposit institutions in the amount of $6.9 million and $4.4 million of which $760,000 and $203,000 is denominated in foreign currencies in foreign institutions as of March 31, 2022 and December 31, 2021, respectively. As of March 31, 2022 and December 31, 2021, the Company held cash equivalents in the amount of $16.6 million and $51.1 million, respectively.

Restricted Cash

Pursuant to a contractual agreement to maintain the business credit card, the Company must maintain restricted cash deposits which amounted to approximately $201,000 and $201,000 as of March 31, 2022 and December 31, 2021, 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, BARDA receivables and other receivables. As of March 31, 2022 and December 31, 2021, substantially all of the Company’s cash was deposited in accounts at financial institutions, and amounts may exceed federally insured limits. Management believes that the Company is not exposed to significant credit risk due to the financial strength of the depository institutions in which its cash is held.

As of March 31, 2022 no single commercial customer accounted for more than 10% of total revenues or net accounts receivable. BARDA revenue for emergency deployment accounted for approximately 1% and 47% of total revenues for the three months ended March 31, 2022 and 2021, respectively. BARDA receivables for emergency preparedness services accounted for 1% and 3% of total BARDA receivables as of March 31, 2022 and December 31, 2021, respectively. See table below for breakdown of BARDA receivables (in thousands).

	As of March 31, 2022		As of December 31, 2021
BARDA procurement and emergency preparedness services	$	8	$	9
BARDA expense reimbursements		674		299
Total BARDA receivables	$	682	$	308

Marketable Securities

We classify all highly liquid investments with original maturities of three months or less from the date of purchase as cash equivalents and all highly liquid investments with stated maturities of greater than three months as marketable securities. The Company classifies marketable securities as short-term when they have remaining contractual maturities of one year or less from the balance sheet date, and as long-term when the investments have remaining contractual maturities of more than one year from the balance sheet date. Classification is determined at the time of purchase and re-evaluated each balance sheet date. Short-term marketable securities represent investment of cash available for current operations. We account for our marketable securities as available-for-sale securities.

All marketable securities, which consist of corporate debt securities, U.S government agency obligations, U.S treasury and commercial paper are denominated in the U.S. dollars, have been classified as “available for sale”, and are carried at fair value. Unrealized gains and losses, net of any related tax effects, are excluded from earnings and are included in other comprehensive income (loss) and reported as a separate component of stockholders equity until realized. Realized gains and losses on marketable securities are included in other income in the accompanying Consolidated Statements of Operations. The cost of any marketable securities sold is based on the specific identification method. The amortized cost of marketable securities is adjusted for amortization of premiums and accretion of discounts to maturity. Interest on marketable securities is included in other income. In accordance with the Company’s investment policy, management invests to diversify credit risk and only invests in securities with high credit quality, including U.S. government securities, and the maximum final maturity from the date of purchase is thirty-seven months.

If necessary, the Company will recognize an allowance for credit losses on available-for-sale debt securities on an individual basis, and will no longer consider other than-temporary impairment or immediately reduce the cost basis of the investment provided that it is more likely than not that the security will be held to recovery or maturity. Further, the Company will recognize any improvements in estimated credit losses on available-for-sale debt securities immediately in earnings and reduce the existing allowance for credit losses. The Company will disaggregate its available-for-sale debt securities into the following categories: commercial paper, corporate debt, government and agency securities and money market funds. The Company’s corporate bonds are comprised of predominantly high-grade corporate bonds while its government and agency securities are U.S. treasury bonds, and U.S. agency bonds. The Company has analyzed both corporate bonds and government and agency securities and identified that both types of securities have similar risk characteristics in that they are traded infrequently and have contractual interest rates and maturity dates.

To evaluate for impairment, management reviews credit rating changes, securities trends, interest rate movements and unrealized loss at the security level of the Company’s available for sale debt securities. If any of these give rise to a potential credit concern, the Company performs a discounted cash flow analysis to determine the credit portion of the impairment. The discounted cash flow analysis will be performed either internally or through the assistance of a qualified third party. Once the credit component of the impairment is determined, the Company will record the impaired amount as an allowance to the available-for-sale debt securities balance and as a charge to other income in the accompanying Consolidated Statements of Operations, not to exceed the amount of the unrealized loss. The Company assesses expected credit losses at the end of each reporting period and adjusts the allowance through other income.

BARDA Income and Receivables

The AVITA Group was awarded a Biomedical Advance Research and Development Authority (“BARDA”) contract in September 2015. The contract with BARDA expires December 31, 2023. Under this arrangement BARDA supported the Company’s research and development for the Company’s product, including the U.S. clinical regulatory program targeted towards PMA, our compassionate use program, clinical and health economics research. Currently, the BARDA contract is supporting the Company’s clinical trial in soft-tissue reconstruction.

Consideration received under the BARDA arrangement is earned and recognized under a cost-plus-fixed-fee arrangement in which the Company is reimbursed for direct costs incurred plus allowable indirect costs and a fixed-fee earned. Billings under the contracts are based on approved provisional indirect billing rates, which permit recovery of fringe benefits, general and administrative expenses and a fixed fee.

The Company has concluded that grants under the BARDA arrangement are not within the scope of ASC 606, as it does not meet the definition of a contract with a “customer.” The Company has further concluded that Subtopic 958-605, Not-for-Profit-Entities-Revenue Recognition also does not apply, as the Company is a business entity and the payments are with governmental agencies or units. With respect to the BARDA arrangement, we considered the guidance in IAS 20, Accounting for Government Grants and Disclosure of Government Assistance, by analogy. BARDA income and related receivables are recognized when there is reasonable assurance that the amount will be received, and all attaching conditions have been complied with. When the payment relates to an expense item, the amount received is recognized as income over the period when the expense was incurred.

Leases

The Company has operating leases for corporate office space, manufacturing and warehouse facility. The Company’s operating leases have remaining lease terms of one year to two years, some of which include options to renew the lease. At contract inception, the Company determines whether the contract is a lease or contains a lease. A contract contains a lease if the Company is both able to identify an asset and can conclude it has the right to control the identified asset for a period of time. Leases with an initial term of twelve months or less are not recorded on the condensed consolidated balance sheet.

Right of use (“ROU”) assets represent the Company’s right to control an underlying asset for the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an explicit rate, the Company used its incremental borrowing rate (“IBR”) based on the information available at commencement date in determining the discount rate used to present value lease payments. In determining the IBR, the Company considered its credit rating and current market interest rates. The IBR used approximates the interest that the Company would be required to pay for a collateralized loan over a similar term. The Company’s leases typically do not include any residual value guarantees or asset retirement obligations.

The Company’s lease terms are only for periods in which it has enforceable rights. A lease is no longer enforceable when both the lessee and the lessor each have the right to terminate the lease without permission from the other party with no more than an insignificant penalty. The Company has options to renew some of these leases for three years after their expiration. The Company considers these options, which may be elected at the Company’s sole discretion, in determining the lease term on a lease-by-lease basis. Lease expense is recognized on a straight-line basis over the lease term and is primarily included in general and administrative expenses in the accompanying consolidated statements of operations.

The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component for all underlying asset classes. Some leases require variable payments for common area maintenance, property taxes, parking, insurance and other variable costs. The variable portion of lease payments is not included in operating lease assets or liabilities. Variable lease costs are expensed when incurred.

Share-based Compensation

Share-based compensation

The Company records compensation expense for stock options based on the fair market value of the awards on the date of grant. The fair value of share-based compensation awards is amortized over the vesting period of the award. Compensation expense for performance-based awards is measured based on the number of shares ultimately expected to vest, estimated at each reporting date based on management’s expectations regarding the relevant performance criteria, if any. The Black-Scholes option pricing model and Monte Carlo Simulation were used to estimate the fair value of the time-based and performance-based options, respectively. Under ASU 2016-09, Compensation – Stock Compensation (“ASC 718”) Improvements to Employee Share-Based Payment Accounting, the Company elected to account for forfeitures as they occur.

The following assumptions were used in the valuation of stock options.

•

Expected volatility – determined using the average of the historical volatility using daily intervals over the expected term and the derived volatility using the longest term available of 12 months.

•

Expected dividends - based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future

•

Expected term – the expected term of the Company’s stock options for tenure only vesting has been determined utilizing the “simplified” method as described in the SEC’s Staff Accounting Bulletin No. 107 relating to share-based compensation. The simplified method was chosen because the Company has limited historical option exercise experience due to its short operating history of awards granted, the first plan was established in 2016 and was primarily used for Executives awards. Further, the Company does not have sufficient history of exercises in the U.S. market given the recent redomiciliation to the United States during 2020. The expected term of options with a performance condition was set to the contractual term of 10 years.

•

Risk-free interest rate – the risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant for a period approximately equal to the expected term of the award.

Segment Reporting

Operating segments are defined as components of an enterprise for which separate discrete financial information is available for evaluation by the chief operating decision-maker in making decisions regarding resource allocation and assessing performance. The Company’s chief operating decision maker is its Chief Executive Officer. To date, the Company has viewed its operations and manages its business as one segment.

Deferred Compensation Plan and Investments in Corporate-Owned Life Insurance

The Company’s Deferred Compensation Plan (the "DCP"), which became effective on October 2021, allows highly compensated key employees to elect to defer a portion of their salary, bonus, commissions and RSU awards to later years. Management determined that the DCP shall be accounted for similar to a defined benefit plan under ASC 715, Compensation – Retirement Benefits, and should follow accounting treatment similar to a cash balance plan. Management determined that the employee portion and employer portion of the deferred compensation should be recognized as compensation expense with a corresponding credit to deferred compensation liability. The matching contribution will be accrued over the vesting period of two-years with 25% vesting in the first year and 75% vesting in the second year. Employees aged 55 or older immediately vest in employer matching contributions. The change in the liability between each reporting period is accounted for as compensation expense with a corresponding adjustment to deferred compensation liability. Upon distribution, the Company will record the distribution as a decrease to compensation liability with corresponding credit to cash. The Company funds the DCP through a Corporate-Owned Life Insurance (“COLI”). Per the ASC 325-30-25-1A, Investments – Other, COLI is recorded as an asset in other long-term assets as it does not meet the definition of a plan asset under ASC 715. The Company invests in COLI policies relating to its deferred compensation plan. Investments in COLI policies are recorded at their cash surrender values as of each balance sheet date. Changes in the cash surrender value during the period are recorded as a gain or loss in the statement of operations in other income.

Equity [Abstract]

Common and Preferred Stock

13. Common and Preferred Stock

The Company’s CHESS Depositary Interests ("CDIs") are quoted on the ASX under the ticker code, “AVH”. The Company’s shares of common stock are quoted on NASDAQ under the ticker code, “RCEL”. One share of common stock on NASDAQ is equivalent to five CDIs on the ASX.

As a result of the ‘implicit consolidation’ that occurred under the AVITA group's redomiciliation from Australia to the United States of America, the number of shares of common stock on issue in the Company (as set out in the consolidated financial statements) is less than the number of ordinary shares in AVITA Medical (the prior parent company of the AVITA group) that was previously set out in the consolidated financial statements of AVITA Medical. All common share amounts included in the consolidated financial statements have been retroactively reduced by a factor of one hundred and all per share amounts have been increased by a factor or one hundred, with the exception of the Company’s common stock par value.

The Company is authorized to issue 200,000,000 shares of common stock, par value $0.0001 per share, and 10,000,000 shares of preferred stock, par value $0.0001 per share, issuable in one or more series as designated by the Company’s board of directors. No other class of capital stock is authorized. As of March 31, 2022, and December 31, 2021, 24,955,581 and 24,925,743 shares of common stock, respectively, were issued and outstanding and no shares of preferred stock were outstanding.

- Definition

The entire disclosure for shareholders' equity comprised of portions attributable to the parent entity and noncontrolling interest, including other comprehensive income. Includes, but is not limited to, balances of common stock, preferred stock, additional paid-in capital, other capital and retained earnings, accumulated balance for each classification of other comprehensive income and amount of comprehensive income.

Accounting Changes And Error Corrections [Abstract]

Accounting Standards Update

3. Accounting Standards Update

Recently Adopted Accounting Pronouncements

In November 2021, the FASB issued ASU 2021-10, “Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance.” ASC 832 requires business entities to provide certain disclosures when they (1) have received government assistance and (2) use a grant or contribution accounting model by analogy to other accounting guidance. The guidance will require business entities to disclose the nature of the transactions, accounting policies used to account for the transactions, and state which line items on the balance sheet and income statement are affected by these transactions and the amount applicable to each financial statement line. Business entities will also have to disclose significant terms and conditions of transactions with a government such as the duration of the agreement, any commitments made by either side, provisions, and contingencies. The guidance in ASU 2021-10 is effective for all entities for fiscal years beginning after December 15, 2021. Entities may apply the provision either (1) prospectively to all transactions within the scope of ASC 832 that are reflected in the financial statements as of the adoption date and all new transactions entered into after the date of adoption or (2) retrospectively. The Company adopted this standard as of January 1, 2022. The adoption did not have a material impact on the Consolidated Financial Statements or disclosures.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, or ASU 2019-12, which includes amendments to simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC 740, Income Taxes, or ASC 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. The new guidance is effective for the Company for annual periods beginning after December 15, 2021 and interim periods within fiscal years beginning after December 15, 2022. Early adoption of the amendments is permitted. The Company adopted this standard as of January 1, 2022. The adoption did not have a material impact on the Consolidated Financial Statements.

Recent Accounting Pronouncements Not Yet Adopted

All other newly issued but not yet effective accounting pronouncements have been deemed to be not applicable or immaterial to the Company.

- Definition

The entire disclosure for change in accounting principle. Includes, but is not limited to, nature, reason, and method of adopting amendment to accounting standards or other change in accounting principle.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

5. Fair Value Measurements

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 Company’s Level 1 assets include money market instruments and are valued based upon observable market prices. Level 2 assets consist of commercial paper, U.S Government agency obligations, corporate debt securities and U.S Treasury securities. Level 2 securities are valued based upon observable inputs that include reported trades, broker/dealer quotes, bids and offers. As of March 31, 2022 and December 31, 2021, the Company had no investments that were measured using unobservable (Level 3) inputs. There were no transfers between fair value measurement levels during the quarter ended March 31, 2022 or the transition period ended December 31, 2021.

The net operating loss carryforwards may be subject to limitation regarding their utilization against taxable income in future periods due to “change of ownership” provisions of the Internal Revenue Code and similar state and foreign provisions. Of these carryforwards, $21.7 million will expire, if not utilized, between 2026 through 2038. The state carryforwards begin to expire between 2026 through 2041. The remaining carryforwards have no expiration. The Company is forecasting current year losses and has full valuation allowances against its deferred tax assets. Tax expense for the three months ended March 31, 2022 and 2021 of $4,000 and $10,000, respectively, is related to state minimum taxes.

In assessing the recoverability of its deferred tax assets, the Company considers whether it is more likely than not that its deferred assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income in those periods in which temporary differences become deductible and/or net operating losses can be utilized. The Company considers all positive and negative evidence when determining the amount of the net deferred tax assets that are more likely than not to be realized. This evidence includes, but is not limited to, historical earnings, scheduled reversal of taxable temporary differences, tax planning strategies and projected future taxable income. Based upon the weight of available evidence including the uncertainty regarding the Company’s ability to utilize certain net operating losses and tax credits in the future, the Company has established a valuation allowance against its net deferred tax assets of $51.3 million and $46.9 million as of December 31, 2021 and 2020, respectively. The deferred tax assets are primarily net operating loss carryforwards for which management has determined it is more likely than not that the deferred tax assets will not be realized.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements related to a particular tax position are measured based on the largest benefit that has a greater than a 50% likelihood of being realized upon settlement. The amount of unrecognized tax benefits is adjusted as appropriate for changes in facts and circumstances, such as significant amendments to existing tax law, new regulations or interpretations by the taxing authorities, new information obtained during a tax examination, or resolution of an examination.

The Company has not identified any uncertain tax positions as of March 31, 2022 or December 31, 2021.

The Company files income tax returns in the U.S. federal, California and certain other state and foreign jurisdictions. The Company remains subject to income tax examinations for its U.S. federal and state income taxes generally for fiscal years ended

June 30, 2006 and forward. The Company also remains subject to income tax examinations for international income taxes for fiscal years ended June 30, 2018 through June 30, 2021, and for certain other U.S. state and local income taxes generally for the fiscal years ended June 30, 2018 through June 30, 2021.

- 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.

Net Loss Per Share

17. Net Loss per Share

The following is a reconciliation of the basic and diluted loss per share computations:

	Three months ended March 31,
	(in thousands, except per share data)
	2022			2021
Net Loss	$	(9,463	)	$	(5,997	)
Weighted-average common shares – outstanding, basic		24,938			22,734
Weighted-average common shares – outstanding, diluted		24,938			22,734
Net loss per common share, basic	$	(0.38	)	$	(0.26	)
Net loss per common share, diluted	$	(0.38	)	$	(0.26	)

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. 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 ended March 31, 2022 and 2021, diluted net loss per common share is the same as the basic net loss per share for those periods.

Contingencies

12. 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 to be a better estimate 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 March 31, 2022 and December 31, 2021, the Company did not have any outstanding or threatened litigation that would have a material impact to the financial statements.

Revenue Performance Obligation [Abstract]

Revenues

14. Revenues

Revenues

The Company’s revenue consists of sale of the RECELL System to hospitals or other treatment centers and to BARDA (collectively “customers”), predominately in the United States. In addition, the Company records service revenue for the emergency preparedness services provided to BARDA.

Performance Obligations

For commercial contracts, we identified the hospital or treatment center as the customer in Step 1 of the 5-step model of ASC 606 and have determined a contract exists with those customers. As these contracts typically have a single performance obligation (i.e. product delivery), no allocation of the transaction price is required in Step 4 of the model. Control of the product is transferred to the customer at a point in time, at the point in time at which the goods are either shipped or delivered to our customers’ facilities, depending on the terms of the contract. The transaction price is stated within the contract and is therefore fixed consideration. The transaction price does not include the sales tax that are imposed by governmental authorities.

For the contract with BARDA, the Company identified two performance obligations (i) the procurement of 5,614 RECELL units; and (ii) emergency preparedness services. The Company’s performance obligations are either satisfied at a point in time or over time as services are provided. The product procurement performance obligation is satisfied at a point in time, upon transfer of control of the product. RECELL units that have been delivered to BARDA have a product replacement obligation at no cost to BARDA due to product’s limited shelf-life. The estimated cost of the expired inventory over the term of the contract is recognized on a per unit basis at the time of delivery. The liability is released upon replacement of the product along with a corresponding reduction to inventory. The Company has estimated deferred cost of approximately $52,000 and $64,000 as of March 31, 2022 and December 31, 2021, respectively, for the rotation cost of the product. Such amounts are recorded in other current liabilities and other long-term liabilities as of March 31, 2022 and December 31, 2021, respectively. The emergency preparedness services performance obligation is satisfied over time. Revenue for the emergency deployment will be recognized on a straight-line basis during the term of the contract as services are consumed over time. Services recognized for the three months ended March 31, 2022 and 2021 were $93,000 and $58,000, respectively, and are included in sales within the consolidated statement of operations. Contract costs to fulfil the performance obligation are incremental and expected to be recovered are capitalized and amortized on a straight-line basis over the term of the contract. As of March 31, 2022 and December 31, 2021 contract costs of $441,000 and $504,000 are included in other long-term assets, respectively.

Remaining Performance Obligations

Revenues from remaining performance obligations are calculated as the dollar value of the remaining performance obligations on executed contracts. The estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) pursuant to the Company’s existing customer agreements is $882,000 and $952,000 as of March 31, 2022 and December 31, 2021, respectively. Approximately $447,000 for March 31, 2022 and $517,000 for December 31, 2021 of the total balance relates to our July 2020 contract with BARDA for the purchase, delivery and storage of RECELL Systems for emergency response preparedness for a period of three years. The Company expects to recognize this amount as services are provided to BARDA. For the remaining balance of $435,000 as of March 31, 2022 and December 31, 2021, the Company expects to recognize revenue on a straight-line basis over the term of the contract upon generation of sales for with Cosmotec. For the contract with BARDA, we recognized $93,000 and $58,000 of service revenue related to the emergency readiness performance obligation during the three months ended March 31, 2022 and 2021. We are contracted to manage this inventory of product until the federal government requests shipment or at contract termination on December 31, 2023.

Variable Consideration

The Company evaluates its contracts with customers for forms of variable consideration, which may require an adjustment to the transaction price based on their estimated impact. For commercial customers, revenue from the sale of goods is recognized net of volume discounts. The Company uses the expected value method when estimating variable consideration. Revenue is only recognized to the extent that it is probable that a significant reversal will not occur. Variable consideration under the BARDA contract is not material to the 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 the period ended March 31, 2022 and December 31, 2021, 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. The Company had $882,000 and $952,000 of contract liabilities as of March 31, 2022 and December 31, 2021, respectively. The balance relate to the unsatisfied performance obligation for emergency preparedness under the BARDA contract and Cosmotec. Performance obligation will be satisfied, and revenue will be recognized over time over the term of the contract. For the three months ended March 31, 2022 and 2021, the Company recognized $93,000 and $58,000 of revenue from amounts included in the beginning balance of contract liabilities.

Cost to Obtain and Fulfill a Contract

Commercial contract fulfillment costs include commissions and shipping expenses. The Company has opted to immediately expense the incremental cost of obtaining a contract when the underlying related asset would have been amortized over one year or less. The Company generally does not incur costs to obtain new contracts.

BARDA Contract Costs

Cost to fulfill the BARDA emergency preparedness performance obligation, which primarily consist of billed costs to BARDA incurred in connection with the emergency deployment services, are incremental and expected to be recovered. Costs are capitalized and amortized on a straight-line basis over the term of the contract. As of March 31, 2022 and December 31, 2021, the Company had $441,000 and $504,000 of contracts costs included in other long-term assets. Amortization expense related to deferred contract costs were $85,000 and $50,000, during the three months ended March 31, 2022 and 2021, respectively, and are classified as cost of sales on the accompanying consolidated Statements of Operations. There was no impairment loss in relation to deferred contract costs during the three months ended March 31, 2022 and 2021.

Disaggregated Revenue

The Company disaggregates revenue from contracts with customers into geographical regions and by customer type. As noted in the segment footnote, the Company’s business consists of one reporting segment. A reconciliation of disaggregated revenue by geographical region and customer type is provided in Segment Note 11.

- 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.

The Company

1. The Company

Nature of the Business

The AVITA group of companies (comprising AVITA Medical, Inc. (“AVITA” or the “Company”) and its subsidiaries, including AVITA Medical Pty Limited, previously known as AVITA Medical Limited, (“AVITA Medical”)) (collectively, “AVITA Group” or “we”, “us”, or “our”) is a commercial-stage regenerative medicine company focused on the treatment of burns, trauma and other acute injuries, together with skin defects like vitiligo. The Company’s lead product is the RECELL® System, a device that enables healthcare professionals to produce a suspension of Spray-On Skin™ Cells using a small sample of the patient’s own skin. In September 2018, the United States Food & Drug Administration (“FDA”) granted premarket approval (“PMA”) to the RECELL System for use in the treatment of acute thermal burns in patients eighteen years and older. Following receipt of our original PMA, we commenced commercializing the RECELL System in January 2019 in the United States. In June 2021 the FDA approved an expanded indication to include treatment of pediatric acute full-thickness thermal burns. In February 2022, the FDA approved a PMA supplement for the RECELL® Autologous Cell Harvesting Device with enhanced ease-of-use, aimed at providing clinicians a more efficient user experience and simplified workflow. In addition, the FDA has granted the Company Investigational Device Exemptions (“IDEs”) which have enabled the Company to initiate pivotal clinical trials to further expand the approval of the RECELL System for soft tissue reconstruction and vitiligo. Enrollment of those clinical trials is complete and, if successful, those studies would enable the Company to seek FDA approval to market the RECELL System in the United States in those indications.

In February 2019 we entered into a collaboration with COSMOTEC, an M3 Group company, to market and distribute the RECELL System in Japan. We worked with COSMOTEC to advance our application for approval of the RECELL System in Japan pursuant to Japan’s Pharmaceuticals and Medical Devices Act (“PMDA”). In February 2022, COSMOTEC’s application for regulatory approval was approved by the PMDA initially with labelling for burns only. COSMOTEC plans to commercially launch RECELL in Japan following Japan’s Ministry of Health, Labour, and Welfare approval of reimbursement pricing. Once soft tissue and vitiligo data are available from the Company’s related U.S. clinical trials, COSMOTEC plans to submit a further application for soft tissue and vitiligo indications.

In March 2020, the World Health Organization declared the outbreak of a novel strain of the coronavirus (“COVID-19”) a pandemic. We continue to closely monitor the recent developments surrounding the continued spread and potential resurgence of COVID-19 due to existing and future variants. As a result of the pandemic, our customers (primarily hospitals) are experiencing disruptions with respect to a shortage in operating room personnel. Although the number of U.S. hospitalizations due to COVID-19 has decreased in the last several months and many government imposed restrictions have been lifted, we continue to be unable to predict the full impact that the ongoing COVID-19 pandemic will have on our future results of operations, liquidity and financial condition due to numerous uncertainties, including the duration of the pandemic, the actions that may be taken in the future by government authorities across the United States in response to new variants. The Company has assessed the potential impact of COVID-19 on certain accounting matters including, but not limited to, the allowance for doubtful accounts, inventory reserves and return reserves, and impairment considerations for long-lived assets, marketable securities and intangibles, as of March 31, 2022 and through the date of this report. With respect to future operating results, it is not possible at this time to predict, with any degree of precision, the effects of COVID-19. Consequently, actual results for accounting estimates and assumptions, particularly those relating to the recoverability of certain intangible assets and estimates of expected credit losses on accounts receivable could differ from these estimates. However, we do not currently believe that COVID-19 will result in any significant changes in costs going forward. We will continue to monitor the performance of our business and reassess the impacts of COVID-19 and its variants.
