The aggregate fair value of stock options vested during the fiscal years ended January 31, 2024 and 2025 was $6.1 million and $4.8 million, respectively.

As of January 31, 2025 , unrecognized stock-based compensation expense related to unvested stock options was $1.3 million, which is expected to be recognized over a weighted-average period of 1.1 years.

The fair value of each stock option grant is estimated on the date of grant using the BSM option-pricing model. No options were granted during the fiscal years ended January 31, 2024 and 2025 . The following weighted-average assumptions were used to estimate the fair value of options issued, if any:

• Expected term—The expected term represents the period that the stock-based awards are expected to be outstanding. For option grants that are considered to be “plain vanilla,” the Company determines the expected term using the simplified method. The simplified method

• Expected dividend yield—The expected dividend is assumed to be zero as the Company has never paid dividends and has no current plans to do so.

• Fair value per share of the Company’s common stock—The fair value of the common
