Except as set forth herein, the Original 8-K is not amended. This Amendment supplements the Original 8-K and should be read in conjunction with the Original 8-K.

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

The information set forth in Item 5.02 of the Original 8-K is hereby supplemented by the following information regarding the compensatory arrangements for Mr. Sahni.

Compensatory Arrangements for Sanjeev Singh Sahni, Chief Executive Officer

In connection with his appointment as Chief Executive Officer, Mr. Sahni has entered into an amendment (the “Sahni Amendment”) to his employment agreement with the Company dated November 5, 2024 (the “Sahni Agreement”), effective as of the Effective Date.

In addition to the terms of the Sahni Amendment as disclosed in the Original 8-K, Mr. Sahni will be entitled to certain payments and benefits upon a qualifying termination of employment or a change in control, which have been revised pursuant to the Sahni Amendment. Pursuant to the Sahni Amendment, if Mr. Sahni resigns for Good Reason (as defined in the Sahni Agreement) or the Company terminates Mr. Sahni’s employment without Cause (as defined in the Sahni Agreement) not in connection with a Change in Control (as defined in the Company’s 2021 Equity Incentive Plan), then Mr. Sahni will be eligible to receive the following amended severance benefits: (1) 12 months of base salary, less applicable tax withholdings and paid in accordance with the Company’s regular payroll practices; (2) an amount equal to Mr. Sahni’s prorated annual performance bonus for the calendar year in which the termination occurs, based on actual performance metrics and calculated based on the number of days Mr. Sahni was employed during the applicable calendar year, less applicable tax withholdings, to be paid once the bonus calculation for such calendar year has been finalized; (3) up to 18 months of the employer portion of premiums under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) paid by the Company; (4) continued vesting of Mr. Sahni’s outstanding time-based equity awards for a period of 12 months following the date of termination, and continued vesting of Mr. Sahni’s outstanding performance-based stock unit awards for a period of 12 months following the date of termination based on (A) actual or trending performance through the end of such 12-month period, prorated for the period of Mr. Sahni’s service plus the 12-month additional enhanced vesting period, or (B) if actual performance cannot be determined at such time, target performance.

If Mr. Sahni resigns for Good Reason or the Company terminates his employment without Cause within three months prior to or twelve months following the effective date of a Change in Control, then Mr. Sahni will also be eligible to receive the following amended severance benefits: (1) 18 months of base salary, less applicable tax withholdings, paid in a lump sum on the 60th day following the qualifying termination; (2) an amount equal to 150% of Mr. Sahni’s target annual performance bonus for the calendar year in which the termination occurs, less applicable tax withholdings, paid in a lump sum on the 60thday following the qualifying termination; (3) all of Mr. Sahni’s outstanding and unvested time-based and performance-based equity awards (at 100% of target) held immediately prior to the termination date will become fully vested and immediately exercisable; (4) up to 24 months of the employer portion of COBRA premiums paid by the Company; and (5) if such qualifying termination in connection with a Change in Control occurs prior to December 31, 2026, the payment of Mr. Sahni’s one-time cash bonus of $400,000 will be accelerated and paid upon the date of such termination.

As a condition to receiving the severance benefits set forth above, Mr. Sahni must sign and comply with a separation agreement in a form presented by the Company, containing among other terms a general release of claims.

Additionally, the repayment terms applicable to Mr. Sahni’s one-time cash bonus of $400,000, to be paid in December 2026, as disclosed in the Original 8-K are revised to provide that in the event Mr. Sahni is terminated for Cause or he resigns without Good Reason (each as defined in the Sahni Agreement) within the one-year period following the Effective Date, he will be required to repay a pro-rated portion of the after-tax amount of this one-time cash bonus based on the time served within the one-year period.

Except as set forth above or as described in the Original 8-K, the terms of Mr. Sahni’s employment will remain in effect or as set forth in the Sahni Agreement.

The foregoing summary of the Sahni Amendment does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Sahni Amendment, a copy of which will be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2026.
