During the three months ended September 27, 2025, certain of the Company’s directors or officers (as defined in Rule 16a-1(f) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) entered into contracts, instructions, or written plans for the purchase or sale of our securities that are intended to satisfy the conditions specified in Rule 10b5-1(c) under the Exchange Act for an affirmative defense against liability for trading in securities on the basis of material nonpublic information. We refer to these contracts, instructions, and written plans as “Rule 10b5-1 Trading Plans” and each one as a “Rule 10b5-1 Trading Plan.”

We describe the material terms of all such trading plans below.

On August 18, 2025, Kevin Holleran, a director and our President and Chief Executive Officer, entered into a Rule 10b5-1 Trading Plan that provides that Mr. Holleran, acting through a broker, may sell up to an aggregate of 514,335 shares of our common stock. Sales of shares under the plan may only occur from January 5, 2026 to June 30, 2026. The plan is scheduled to terminate on June 30, 2026, subject to earlier termination upon the sale of all shares subject to the plan, upon termination by Mr. Holleran or the broker, or as otherwise provided in the plan.
