As of April 30, 2026 and October 31, 2025, the Company classified its government agency marketable securities as Level 2 within the valuation hierarchy. The Company estimates the fair value of these marketable securities by taking into consideration valuations obtained from third-party pricing sources. These pricing sources utilize industry standard valuation models, including both income and market-based approaches, for which all significant inputs are observable, either directly or indirectly to estimate fair value. These inputs include market pricing based on real time trade data for the same or similar securities, issuer credit spreads, benchmark yields, and other observable inputs.

During the three and six months ended April 30, 2026 and 2025, there were no transfers or reclassifications between fair value measurement levels of assets or liabilities. The carrying values of all other financial current assets, accounts payable and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities.
