Summary of significant accounting policies

Basis of presentation and use of estimates

The accompanying unaudited condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information. Certain information and disclosures normally included in the consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes included in the Annual Report on Form 10-K for the fiscal year ended September 30, 2023 (the Annual Report on Form 10-K) filed with the Securities and Exchange Commission on November 21, 2023. The condensed consolidated financial statements are unaudited and have been prepared on a basis consistent with that used to prepare the audited annual consolidated financial statements and include, in the opinion of management, all adjustments, consisting of normal and recurring items, necessary for the fair statement of the condensed consolidated financial statements. The condensed consolidated balance sheet at September 30, 2023 is derived from audited consolidated financial statements but does not include all disclosures required by GAAP. The operating results for the three and nine months ended June 30, 2024 are not necessarily indicative of the results expected for the full year ending September 30, 2024 or any interim period.

The presentation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Company’s unaudited

condensed consolidated financial statements include its wholly owned subsidiaries. All intercompany balances and accounts are eliminated in consolidation.

To conform with current fiscal 2024 presentation, we reclassified $3.6 million of impairment of property and equipment included within restructuring and other costs to impairment of long-lived assets in the condensed consolidated statement of operations and comprehensive loss for the three and nine months ended June 30, 2023. This reclassification had no impact on our condensed statement of operations and comprehensive loss for the three and nine months ended June 30, 2023.

The following table provides a reconciliation of the Company’s cash and cash equivalents and non-current portion of restricted cash reported within the unaudited condensed consolidated balance sheets that sum to the total cash, cash equivalents and restricted cash shown in the Company’s condensed consolidated statements of cash flows:


(in thousands)	June 30, 2024		September 30, 2023
Cash and cash equivalents	$	239,142	$	286,470
Restricted cash, non-current	2,895		2,811
Total cash, cash equivalents and restricted cash	$	242,037	$	289,281

Restricted cash represents cash held at financial institutions that are pledged as collateral for stand-by letters of credit for lease commitments and is included in non-current assets.

Significant accounting policies

There have been no material changes in the accounting policies from those disclosed in the audited consolidated financial statements and the related notes included in the Annual Report on Form 10-K other than disclosed below.

Allowance for Credit Losses

The Company maintains an allowance for credit losses for expected uncollectible accounts receivable and contract assets, which is recorded as an offset to accounts receivable or contract assets and provisions for credit losses are recorded in general and administrative expense in the consolidated statements of income. Under the application of Accounting Standards Codification (“ASC”) Topic 326-20, Financial Instruments—Credit Losses (“ASC 326”), the allowance for current expected credit losses is based on a review of customer accounts and considers historical credit loss information that is adjusted for current economic and business conditions and anticipated future economic events that may impact collectability. In developing its expected credit loss estimate, the Company evaluated the appropriate grouping of accounts receivable and contract assets based upon its evaluation of risk characteristics, including consideration of region and industries of the customers. The allowance for credit losses is reviewed on a quarterly basis to assess the adequacy of the allowance. Allowance for credit losses was $0.7 million as of June 30, 2024.

Short-term investments

The Company invests in various types of securities, including United States government, commercial paper, and corporate debt securities. The Company classifies its investments as available-for-sale and records them at fair value based upon market prices at period end. For available-for-sale debt securities in an unrealized loss position, the Company evaluates whether a current expected credit loss exists based on available information relevant to the credit rating of the security, current economic conditions and reasonable and supportable forecasts. The allowance for credit loss is recorded in other income (expense), net, on the consolidated statements of income, not to exceed the amount of the unrealized loss. Any excess unrealized loss other than the credit loss is recognized in accumulated other comprehensive income or loss in the stockholders' equity section of the consolidated balance sheets. The cost of securities sold is based on the specific identification method and realized gains and losses are included in other income (expense), net. Dividend and interest income are recognized when earned. The Company may sell these securities at any time for use in current operations. There was no allowance for credit losses relating to the short-term investments recognized as of June 30, 2024.

Revenue

The Company had contract assets of $2.6 million and contract liabilities of $2.9 million as of June 30, 2024. The Company had contract assets of $2.8 million and contract liabilities of $3.0 million as of September 30, 2023. For the three and nine months ended June 30, 2024, the Company recognized revenue of $0.7 million and $2.9 million, respectively, from the amount that was included in the contract liability balance at the beginning of each period. For the three and nine months ended June 30, 2023, the Company recognized revenue of $0.6 million and $2.8 million, respectively, from the amount that was included in the contract liability balance at the beginning of each period. In addition, for all periods presented, there

was no revenue recognized in a reporting period from performance obligations satisfied in previous periods. The aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied as of June 30, 2024 was $7.1 million. The Company expects to recognize revenue over the next twelve months relating to performance obligations unsatisfied as of June 30, 2024.

Based on the nature of the Company's contracts with customers, which are recognized over a term of less than 12 months, the Company has elected to use the practical expedient whereby costs to obtain a contract are expensed as they are incurred.

The Company states its revenues net of any taxes collected from customers that are required to be remitted to various government agencies. The amount of taxes collected from customers and payable to governmental entities is included on the balance sheet as part of “Accrued expenses and other current liabilities.”

Recent accounting pronouncements

Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s ASC. The Company considered the applicability and impact of all recent ASUs. ASUs not listed below were assessed and determined to be not applicable to the Company’s consolidated financial position and results of operations.

Recent accounting pronouncements adopted

In June 2016, FASB issued ASU No. 2016-13 “Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments” and has since modified the standard with several ASUs (collectively, “Topic 326”). Topic 326 requires measurement and recognition of expected credit losses for financial assets. The ASU replaced previous incurred loss impairment guidance and established a single expected credit losses allowance framework for financial assets carried at amortized cost. It also eliminated the concept of other-than-temporary impairment and requires credit losses related to certain available-for-sale debt securities to be recorded through an allowance for credit losses. On October 1, 2023, the Company adopted this standard using a modified retrospective approach, which requires a cumulative-effect adjustment to the opening balance of retained earnings to be recognized on the date of adoption and, accordingly, recorded a net increase of $0.1 million to accumulated deficit as of the beginning of fiscal 2024. In connection with the adoption of Topic 326, the Company made an accounting policy election to not measure an allowance for credit losses for accrued interest receivable.

Recently issued accounting pronouncement not yet adopted

In December 2023, the FASB issued ASU No. 2023-09 "Income Taxes (Topic 740)". The amendments in this ASU require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. The amendments in this update are effective for annual periods beginning after December 15, 2024. The standard is not expected to have a material impact to the Company's condensed consolidated financial statements.

In November 2023, the FASB issued ASU No. 2023-08 "Segment Reporting (Topic 280)". The amendments in this ASU improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The standard is not expected to have a material impact to the Company's condensed consolidated financial statements.

The Company has evaluated other recently issued accounting pronouncements and has concluded that the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s financial position or results of operations upon adoption.
