The consolidated financial statements include the accounts of Astrotech Corporation and its wholly-owned subsidiaries that are required to be consolidated. All intercompany transactions have been eliminated in consolidation.

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that directly affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. Management continuously evaluates its critical accounting policies and estimates, including those used in evaluating the recoverability of long-lived assets, recognition of revenue, valuation of inventory, and the recognition and measurement of loss contingencies, if any. Actual results may vary.

Astrotech recognizes revenue employing the generally accepted revenue recognition methodologies described under the provisions of ASC Topic 606 “Revenue from Contracts with Customers” (“Topic 606”), which was adopted by the Company in fiscal year 2019. The methodology used is based on contract type and how products and services are provided. The guidelines of Topic 606 establish a five-step process to govern the recognition and reporting of revenue from contracts with customers. The five steps are: (i) identify the contract with a customer, (ii) identify the performance obligations within the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations within the contract, and (v) recognize revenue when or as the performance obligations are satisfied.

An additional factor is reasonable assurance of collectability. This necessitates deferral of all or a portion of revenue recognition until collection. During the fiscal year ended June 30, 2021, the Company had two material revenue sources that comprised substantially all of its $334 thousand in revenue. During the fiscal year ended June 30, 2020, the Company recognized revenue from one material customer for a total of $488 thousand.

The Company disaggregates revenue by reporting segment to depict the nature of revenue in a manner consistent with its business operations and to be consistent with other communications and public filings. Refer to Note 15 for additional details of revenues by reporting segment.

Contract Assets and Liabilities. The Company enters into contracts to sell products and provide services, and it recognizes contract assets and liabilities that arise from these transactions. The Company recognizes revenue and corresponding accounts receivable according to Topic 606 and, at times, recognizes revenue in advance of the time when contracts give it the right to invoice a customer. The Company may also receive consideration, per the terms of a contract, from customers prior to transferring goods to the customer. The Company records customer deposits as deferred revenue. Additionally, the Company may receive payments, most typically for service and warranty contracts, at the onset of the contract and before services have been performed. In such instances, the Company records a deferred revenue liability. The Company recognizes these contract liabilities as sales after all revenue recognition criteria are met.

Practical Expedients. In cases where the Company is responsible for shipping after the customer has obtained control of the goods, it has elected to treat the shipping activities as fulfillment activities rather than as a separate performance obligation. Additionally, the Company has elected to capitalize the cost to obtain a contract only if the period of amortization would be longer than one year. The Company only gives consideration to whether a customer agreement has a financing component if the period of time between transfer of goods and services and customer payment is greater than one year.

Product Sales. The Company recognizes revenue from sales of products upon shipment or delivery when control of the product transfers to the customer, depending on the terms of each sale, and when collection is probable. In the circumstance where terms of a product sale include subjective customer acceptance criteria, revenue is deferred until the Company has achieved the acceptance criteria unless the customer acceptance criteria are perfunctory or inconsequential. The Company generally offers customers payment terms of less than one year.

Freight. The Company records shipping and handling fees that it charges to its customers as revenue and related costs as cost of goods sold.

Multiple Performance Obligations. Certain agreements with customers include the sale of equipment involving multiple elements in cases where obligations in a contract are distinct and thus require separation into multiple performance obligations, revenue recognition guidance requires that contract consideration be allocated to each distinct performance obligation based on its relative standalone selling price. The value allocated to each performance obligation is then recognized as revenue when the revenue recognition criteria for each distinct promise or bundle of promises has been met.

The standalone selling price for each performance obligation is an amount that depicts the amount of consideration to which the entity expects to be entitled in exchange for transferring the good or service. When there is only one performance obligation associated with a contract, the entire amount of consideration is attributed to that obligation. When a contract contains multiple performance obligations the standalone selling price is first estimated using the observable price, which is generally a list price net of applicable discount or the price used to sell the good or service in similar circumstances. In circumstances when a selling price is not directly observable, the Company will estimate the standalone selling price using information available to it including our market assessment and expected cost plus margin.

The timetable for fulfilment of each of the distinct performance obligations can range from completion in a short amount of time and entirely within a single reporting period to completion over several reporting periods. The timing of revenue recognition for each performance obligation may be dependent upon several milestones, including physical delivery of equipment, completion of site acceptance test, and in the case of after-market consumables and service deliverables, the passage of time.

The Company’s international operations are subject to certain opportunities and risks, including from foreign currency fluctuations and governmental actions. During fiscal years 2021 and 2020, the Company conducted business in ten and seven countries, respectively. The Company closely monitors its operations in each country in which it does business and seeks to adopt appropriate strategies that are responsive to changing economic and political environments. The Company currently conducts business in the U.S. dollar and the Euro. Weaknesses in one currency in which the Company does business are often offset by strengths in the other currency. Revenues, costs, and expenses are translated at the applicable rate on the date of the transaction. Translation gains and losses, if any, are calculated on accounts receivable or accounts payable outstanding at the rate applicable the end of the period. The Company includes gains and losses resulting from foreign currency transactions in income, while it excludes those resulting from translation of financial statements from income and includes them as a component of accumulated other comprehensive loss when applicable. Transaction gains and losses, which were included in the Company’s consolidated statement of operations, amounted to a gain of approximately $3 thousand for the fiscal year ended June 30, 2021 and a loss of approximately $10 thousand for the fiscal year June 30, 2020.

Astrotech offers its customers warranties on the products that it sells. These warranties typically provide for repairs and maintenance of the products if problems arise during a specified time period after original shipment. Concurrent with the sale of products, the Company records a provision for estimated warranty expenses with a corresponding increase in cost of goods sold. The Company periodically adjusts this provision based on historical experience and anticipated expenses. The Company charges actual expenses of repairs under warranty, including parts and labor, to this provision when incurred. The current obligation for warranty provision is included in accrued expenses and other liabilities in the consolidated balance sheets,

whose activity for each of the two fiscal years ended June 30, 2021 and 2020 is summarized in the following table:

(In thousands)	Warranty Provision
Balance as of June 30, 2019	$	3
Warranty claims provided for		22
Settlements made		(7	)
Balance as of June 30, 2020		18
Warranty claims provided for		49
Settlements made		(51	)
Balance as of June 30, 2021	$	16

Research and development costs are expensed as incurred. Research and development costs are used to improve system functionality, streamline and simplify the user experience, and extend our capabilities into customer-defined, application-specific opportunities. Research and development expenses for the fiscal years ended June 30, 2021 and 2020 were $2.7 million and $3.4 million, respectively. This decrease was primarily attributable to a reduction in compensation and related expenses.

Basic net loss per common share is calculated by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per common share is the same as basic net loss per common share as the potential dilutive shares are considered to be anti-dilutive. For more information, see Note 12.

The Company considers short-term investments with original maturities of three months or less to be cash equivalents. Cash equivalents are comprised primarily of operating cash accounts, money market investments, and certificates of deposits.

The carrying value of the Company’s accounts receivable, net of an allowance for doubtful accounts, represents their estimated net realizable value. Astrotech estimates an allowance for doubtful accounts based on type of customer, age of outstanding receivable, historical collection trends, and existing economic conditions. If events or changes in circumstances indicate that a specific receivable balance may be unrealizable, further consideration is given to the collectability of those balances, and the allowance is adjusted accordingly. Receivable balances deemed uncollectible are written off against the allowance. The Company anticipates collecting all unreserved receivables within one year. As of June 30, 2021 and 2020, there was no allowance for doubtful accounts deemed necessary.

The Company computes inventory cost on a first-in, first-out basis, and inventory is valued at the lower-of-cost or net realizable value. The valuation of inventory also requires the Company to estimate obsolete and excess inventory as well as inventory that is not of saleable quality.

Property and equipment are stated at cost, less accumulated depreciation. All furniture, fixtures, and equipment are depreciated using the straight-line method over the estimated useful lives of the respective assets, which is generally five years. Purchased software is typically depreciated over three years. Leasehold improvements are amortized over the shorter of the useful life of the improvement or the term of the lease. Repairs and maintenance are expensed when incurred.

The Company continuously evaluates its long-lived assets for impairment to assess whether the carrying amount of an asset may not be recoverable. Our evaluation is based on an assessment of potential indicators of impairment, such as an adverse change in the business climate that could affect the value of an asset, current or forecasted operating or cash flow losses that demonstrate continuing losses associated with the use of an asset, and a current expectation that, more likely than not, an asset will be disposed of before the end of its previously estimated useful life. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. Recoverability of long-lived assets is dependent on a number of conditions, including uncertainty about future events and demand for our services. Due to the termination of its corporate office lease in August 2021, the Company recorded an impairment of long-lived assets of $173 thousand for the fiscal year ended June 30, 2021 which is included in disposal of corporate lease in the accompanying consolidated statements of operations and comprehensive loss. There was no impairment of long-lived assets recognized during the fiscal year ended June 30, 2020.

Astrotech’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities. Management believes the carrying amounts of these assets and liabilities approximates their fair value due to their liquidity. For more information about the Company’s accounting policies surrounding fair value investments, see Note 6.

Investments that are designated as available-for-sale are reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive loss. The Company determines the cost of investments sold based on a first-in, first-out cost basis at the individual security level. The Company also considers specific adverse conditions related to the financial health of, and the business outlook for, the investee which may include industry and sector performance, changes in technology, operational and financing cash flow factors, and changes in the investee’s credit rating. The Company records other than temporary impairments on marketable equity securities and marketable equity method investments in gains (losses) on equity investments, net of previously recorded gains (losses). For more information on investments, see Note 3.

The Company adopted Accounting Standards Update No. 2016-02, “Leases (Topic 842)” (ASU 2016-02) effective July 1, 2019. ASU 2016-02 requires that the Company determines, at the inception of an arrangement, whether the arrangement is or contains a lease, based on the unique facts and circumstances present. Operating lease assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent its obligation to make lease payments arising from the lease. Right-of-use (“ROU”) assets and operating lease liabilities are recognized at the commencement date of the lease based upon the present value of lease payments over the lease term. When determining the lease term, the Company includes options to extend or terminate the lease when it is reasonably certain, at inception, that the Company will exercise that option. The interest rate implicit in lease contracts is typically not readily determinable; accordingly, the Company uses its incremental borrowing rate, which is the rate that would be incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment, based upon the information available at the commencement date. The lease payments used to determine the Company’s operating lease assets may include lease incentives, stated rent increases and escalation clauses linked to rates of inflation, when determinable, and are recognized in determining its ROU assets. The Company’s operating leases are reflected in the operating lease, right-of-use asset; lease liabilities, current; and lease liabilities, non-current in its consolidated balance sheets.

Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. As a result of the Company’s adoption of ASU 2016-02, it no longer recognizes deferred rent on the consolidated balance sheet. Short-term leases, defined as leases that have a lease term of 12 months or less at the commencement date, are excluded from this treatment and are recognized on a straight-line basis over the term of the lease. Variable lease payments are amounts owed by the Company to a lessor that are not fixed, such as reimbursement for common area maintenance costs for our facility lease, and are expensed when incurred.

Financing leases, formerly referred to as capitalized leases, are treated similarly to operating leases except that the asset subject to the lease is included in the appropriate fixed asset category, rather than recorded as a right-of-use asset, and depreciated over its estimated useful life, or lease term, if shorter. For more information, see Note 4.

The Company accounts for stock-based awards to employees based on the fair value of the award on the grant date. The fair value of stock options is estimated using the expected dividend yields of the Company’s stock, the expected volatility of the stock, the expected length of time the options remain outstanding, and the risk-free interest rates. Changes in one or more of these factors may significantly affect the estimated fair value of the stock options. The Company recognizes forfeitures as they occur. The fair value of awards that are likely to meet goals, if any, are recorded as an expense over the vesting period. For more information, see Note 10.

The Company accounts for income taxes under the liability method, whereby deferred tax asset or liability account balances are determined based on the difference between the financial statement and the tax bases of assets and liabilities using current tax laws and rates in effect for the year in which the differences are expected to affect taxable income. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. A valuation allowance is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized.

The Company records treasury stock at the cost to acquire it and includes treasury stock as a component of stockholders’ equity.

In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes” (“ASU 2019-12”), which removes certain exceptions related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also amends other aspects of the guidance to help simplify and promote consistent application of GAAP. ASU No. 2019-12 is effective for fiscal years beginning after December 15, 2020 (for the Company, the fiscal year ending June 30, 2022), and interim periods within those fiscal years. ASU 2019-12 is not expected to have a material impact on the Company's financial statements.

In May 2021, the FASB issued ASU 2021-04, "Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40)" (“ASU 2021-04”), which provides authoritative guidance for the accounting for modifications or exchanges of freestanding equity-classified written call options (for example, warrants) that remain equity classified after modification or exchange. ASU 2021-04 provides that for an entity that presents earnings per share in accordance with Topic 260, the effects of a modification or an exchange of a freestanding equity-classified written call option that is recognized as a dividend should be an adjustment to net income (or net loss) in the basic earnings per share calculation. The amended guidance becomes mandatorily effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years, and should be applied prospectively to modifications or exchanges occurring on or after the effective date. While the Company does not expect the adoption of ASU 2021-04 to materially impact the Company's consolidated financial statements and related disclosures because it does not currently anticipate modifications to its outstanding equity-classified written call options, the impact on the Company's consolidated financial statements and disclosures will depend on the facts and circumstances of any specific future transactions.
