Principles of consolidation

Principles of consolidation

The accompanying consolidated financial statements have been prepared in conformity with U.S. GAAP and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated.
Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Contingencies

Contingencies

Contingencies are evaluated and a liability is recorded when the matter is both probable and reasonably estimable. Gain contingencies are evaluated and not recognized until the gain is realizable or realized.
Foreign Currency Translation/Transactions

Foreign Currency Translation/Transactions

The Company has determined that the functional currency for its foreign subsidiaries is the local currency. For financial reporting purposes, assets and liabilities denominated in foreign currencies are translated at current exchange rates and profit and loss accounts are translated at weighted average exchange rates. Resulting foreign currency translation adjustments are recognized as other comprehensive income (loss) in the consolidated statements of comprehensive loss and are included as a separate component of stockholders’ equity as accumulated other comprehensive income. Gains or losses resulting from transactions entered into in other than the functional currency are recorded as foreign exchange gains and losses in the consolidated statements of operations.
Fair Value Measurements

Fair Value Measurements

The Company determines fair value measurements used in its consolidated financial statements based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants exclusive of any transaction costs, as determined by either the principal market or the most advantageous market. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy. The basis for fair value measurements for each level within the hierarchy is described below with Level 1 having the highest priority and Level 3 having the lowest.

Level 1 Quoted prices in active markets for identical assets or liabilities.

Level 2 Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets.

Level 3 Valuations derived from valuation techniques in which one or more significant inputs are unobservable.
Cash and cash equivalents

Cash and cash equivalents

Cash and cash equivalents consist of demand deposits with banks and highly liquid money market funds. At April 30, 2025 and July 31, 2024, the Company had cash and cash equivalents in foreign bank accounts of $484 and $391, respectively.
Concentration of Credit Risk

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents and accounts receivable. The Company believes the fair value of the aforementioned financial instruments approximates the cost due to the immediate or short-term nature of these items. At April 30, 2025 and July 31, 2024, the Company had cash deposited in certain financial institutions in excess of federally insured levels. The Company regularly monitors the financial stability of these financial institutions and believes that it is not exposed to any significant credit risk in cash and cash equivalents or restricted cash.

Concentration of credit risk with respect to the Company’s Products segment is mitigated by the diversity of the Company’s customers and their dispersion across many different geographic regions. To reduce risk, the Company routinely assesses the financial strength of these customers and, consequently, believes that its accounts receivable credit exposure with respect to these customers is limited.
Income Taxes

Income Taxes

The Company accounts for income taxes under the liability method of accounting for income taxes. Under 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 existing assets and liabilities and their respective tax bases. The liability method requires that any tax benefits recognized for net operating loss carry forwards and other items be reduced by a valuation allowance when it is more likely than not that the benefits may not be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under the liability method, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The Company carries a valuation allowance equal to domestic and foreign net deferred tax assets as of April 30, 2025 and July 31, 2024. The Company believes that the valuation allowance is necessary as it is not more likely than not that the deferred tax assets will not be realized in the foreseeable future based on positive and negative evidence available at this time. This conclusion was reached because of uncertainties relating to future taxable income, in terms of both its timing and its sufficiency, which would enable the Company to realize the deferred tax assets.
Effect of New Accounting Pronouncements

Effect of New Accounting Pronouncements

Pronouncements Issued but Not Yet Adopted

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amended guidance enhances income tax disclosures primarily related to the effective tax rate reconciliation and income taxes paid information. This guidance requires disclosure of specific categories in the effective tax rate reconciliation and further information on reconciling items meeting a quantitative threshold. In addition, the amended guidance requires disaggregating income taxes paid (net of refunds received) by federal, state, and foreign taxes. It also requires disaggregating individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than five percent of total income taxes paid (net of refunds received). The amended guidance will be effective for our fiscal year beginning August 1, 2025. The guidance can be applied either prospectively or retrospectively. We are currently in the process of evaluating the impact this amended guidance may have on the footnotes to our consolidated financial statements.

In November 2023, FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (ASU 2023-07), which requires an enhanced disclosure of significant segment expenses on an annual and interim basis. This guidance will be effective for our annual period ending July 31, 2025 and our interim periods beginning August 1, 2025. Upon adoption, we expect the guidance will be applied retrospectively to all prior periods presented in the consolidated financial statements. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.

In November 2024, FASB issued ASU No. 2024-03, Disaggregation on Income Statement Expenses (DISE), which specifies additional disclosure requirements. The new guidance requires additional disclosures, including the composition of certain expense line items (such as purchases of inventory, employee compensation, and “other expenses”) and a separate disclosure for selling expenses. This guidance will be effective for our annual period ending July 31, 2028 and our interim periods beginning August 1, 2028. Early adoption is permitted. We are currently evaluating the impact that the adoption of ASU 2024-03 will have on our consolidated financial statement disclosures.

We reviewed all other recently issued accounting pronouncements and have concluded they are not applicable or not expected to be significant to the accounting for our operations.
