Equity Incentive Plan
In March 2021, the Company’s Board of Directors adopted, and the stockholders approved, the 2021 Equity Incentive Plan (“2021 Plan”). The 2021 Plan is a successor to and continuation of the 2013 Stock Plan. The 2021 Plan became effective on the date of the IPO with no further grants being made under the 2013 Stock Plan, however, awards outstanding under the 2013 Stock Plan will continue to be governed by their existing terms. The 2021 Plan provides for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, RSUs, PRSUs, MRSUs and other awards to employees, directors, and consultants. Shares issued pursuant to the exercise of these awards are transferable by the holder. There were 30,054,726 shares available for grant under the 2021 Plan as of March 31, 2026.
RSUs and PRSUs
RSUs granted typically vest over four years. The Company has issued PRSUs which vest based on the achievement of each award’s established performance targets. Depending on the actual financial metrics achieved relative to the target financial metrics throughout the defined performance period of the award, the number of LTIP PRSUs that vest could range from 0% to 200% of the target amount and are subject to the Compensation Committee’s approval of the level of achievement against the approved performance targets.
Assuming the minimum performance level is achieved, one-third of the aggregate number of the achieved LTIP PRSUs shall vest on the later of (i) March 1 of the year after grant or (ii) two trading days following the public release of the Company’s financial results for the year of grant, and the remainder shall vest over the following two years in eight equal quarterly installments subject, in each case, to the individual’s continuous service through the applicable vesting date.
On April 25, 2025, the Company granted an LTIP PRSU award (“2025 LTIP PRSU”). The financial performance level under the PRSUs was equal to the sum of the attainment of certain ARR targets weighted at 75% and adjusted free cash flow margin targets weighted at 25%. On February 13, 2026, the Company determined that the 2025 LTIP PRSU was achieved at 89.0% of the target amount. This resulted in a performance factor reduction of 154,488 shares from the original maximum shares achievable of 278,356, net of forfeiture. The target shares granted under the 2025 LTIP PRSU were 139,178, net of forfeiture.
On March 10, 2026, the Company granted LTIP PRSU awards (“2026 LTIP PRSUs”). The financial performance level under the 2026 LTIP PRSUs can be attained based on the achievement of certain ARR and adjusted free cash flow margin targets. Under the 2026 LTIP PRSUs, 75% of the awards can be achieved based on the ARR targets and 25% of the awards can be achieved based on the adjusted free cash flow margin targets. The target shares granted under the 2026 LTIP PRSUs were 417,215. The actual number of shares that are received under the 2026 LTIP PRSUs may be higher or lower than the target shares based on the actual financial metrics achieved relative to the target financial metrics for fiscal year 2026.
As of March 31, 2026, there was $158,746 of unrecognized stock-based compensation, net of estimated forfeitures, related to outstanding RSUs, that is expected to be recognized over a weighted-average period of 2.9 years. As of March 31, 2026, there was $26,004 of unrecognized stock-based compensation, net of estimated forfeitures, related to outstanding PRSUs that is expected to be recognized over a weighted-average period of 2.9 years.
MRSU
On February 12, 2024, Padmanabhan Srinivasan joined the Company in the role of CEO. As part of his compensation package, Mr. Srinivasan received an MRSU with an estimated grant date fair value of approximately $8,000, which vests upon the satisfaction of certain service conditions and the achievement of certain Company stock price goals during a five-year performance period. A cumulative percentage of the MRSU target is earned based on the achievement of stock price goals, measured based on the average of the Company’s closing stock price over a consecutive 60 trading day period during the performance period as set forth in the table below:

Subsequent to March 31, 2026, the conditions related to the Company Stock Price Target applicable to Tranche 1 of the MRSUs were met. Subject to Mr. Srinivasan's continued service through the applicable vesting dates, 50% of the Tranche 1 MRSUs will vest upon the Compensation Committee’s certification of Company Stock Price Target performance achievement in the first quarter of 2027, and the remaining 50% will vest upon the Compensation Committee's certification in the first quarter of 2029.
As of March 31, 2026, there was $3,457 of unrecognized stock-based compensation related to the MRSU award that is expected to be recognized over a weighted-average period of 2.9 years.
ESPP
In March 2021, the Company’s Board of Directors adopted, and the stockholders approved, the 2021 Employee Stock Purchase Plan (“ESPP”). Eligible employees enroll in the offering period at the start of each purchase period, whereby they may purchase a number of shares at a price per share equal to 85% of the lesser of (1) the stock price at the employee’s first participation in the offering period or (2) the fair market value of the Company’s common stock on the purchase date. The Company’s current offering period began on May 21, 2025 and is expected to end on May 20, 2026. There were 6,040,104 shares available for grant under the ESPP as of March 31, 2026.
