We currently have two employee equity plans that have been adopted by our Board of Directors. These plans, the 2015 Equity Incentive Plan (as amended or otherwise modified, the “2015 Plan”) and the 2015 Employee Stock Purchase Plan (the “2015 ESPP”), are described in more detail in Item 8. Financial Statements and Supplementary Data in our Form 10-K for the year ended January 31, 2025. As of April 30, 2025, 3,363,102 shares and 2,059,623 shares were reserved for future issuance under the 2015 Plan and the 2015 ESPP, respectively.

As of April 30, 2025, there was $482.1 million of unrecognized stock-based compensation expense related to outstanding restricted stock units, inclusive of performance-based and market-based restricted stock units, granted to employees that is expected to be recognized over a weighted-average period of 2.88 years.

We use performance-based incentives for certain employees, including our named executive officers, to achieve our annual financial and operational objectives, while making progress towards our longer-term strategic and growth goals (the “Executive Bonus Plan”). Based on a review of our actual achievement of the pre-established corporate financial objectives and additional inputs from our Compensation Committee, the Executive Bonus Plan for fiscal year 2025 was determined, settled and paid out in the first quarter of fiscal year 2026 in the form of cash and fully vested restricted stock units. During the first quarter of fiscal year 2026, our Compensation Committee also adopted and approved the performance criteria and targets for the Executive Bonus Plan for fiscal year 2026, which is expected to be paid out in the form of cash and fully vested restricted stock units in the first quarter of fiscal year 2027.

During the three months ended April 30, 2025, we recognized stock-based compensation expense related to Executive Bonus Plans in the amount of $4.5 million. The unrecognized compensation expense related to the ungranted and unvested Executive Bonus Plan for fiscal year 2026 is $12.4 million, based on the expected performance against the pre-established corporate financial objectives as of April 30, 2025, which is expected to be recognized over a remaining weighted-average period of less than one year.

As of April 30, 2025, there was $5.6 million of unrecognized stock-based compensation expense related to the 2015 ESPP that is expected to be recognized over a weighted-average period of 1.19 years.
