(c) Trading Plans

In the first quarter of 2026, the following trading plans were adopted orterminated:

• Intended to satisfy the affirmative defense of Rule 10b5-1(c).

** Not intended to satisfy the affirmative defense of Rule 10b5-1(c).

(1)Mr. Kumar modified his existing 10b5-1 plan on March 3, 2026. Pursuant to Rule 10b5-1(c)(1)(iv), the modification to Mr. Kumar's 10b5-1 plan is deemed a termination of his prior plan and an adoption of a new plan. Mr. Kumar is subject to a 90-day cooling off period following the deemed adoption of his new plan before any trading can commence under the modified plan.

(2)The 10b5-1 plan included a representation from the officer to the broker administering the plan that they were not in possession of any material nonpublic information regarding the Company or the securities subject to the plan. A similar representation was made to the Company in connection with the adoption of the plan under the Company’s insider trading policy. Those representations were made as of the date of adoption of the 10b5-1 plan, and speak only as of that date. In making those representations, there is no assurance with respect to any material non-public information of which the officer was unaware, or with respect to any material non-public information acquired by the officer or the Company after the date of the representation.

(3)The aggregate number of RSU Shares that will be available for sale under the Plan is not yet determinable because the shares available will be net of shares sold to satisfy tax withholding obligations that arise in connection with the vesting and settlement of such RSU awards. As such, for purposes of this disclosure, the shares included in this table reflect the aggregate maximum number of shares underlying the holders RSUs without excluding the shares that will be sold to satisfy the tax withholding obligations.
