During the three months ended September 30, 2024, certain of our officers and directors adopted Rule 10b5-1 trading arrangements as follows.

On September 30, 2024, Helen Sabzevari, our Chief Executive Officer and director, Harry Thomasian, our Chief Financial Officer, Donald Lehr, our Chief Legal Officer, Rutul Shah, our Chief Operating Officer, and Phil Tennant, our Chief Commercial Officer, each adopted a trading plan intended to satisfy the conditions under Rule 10b5-1(c) of the Exchange Act. The trading plans provide for the sale, pursuant to a sell-to-cover instruction, of a number of shares of our common stock necessary to satisfy the executive’s tax withholding requirements upon the vesting of PSUs granted to each executive on August 28, 2024 in the following amounts: (i) Ms. Sabzevari,1,650,000 PSUs; (ii) Mr. Thomasian,250,000 PSUs; (iii) Mr. Lehr,108,000 PSUs; (iv) Mr. Shah,250,000 PSUs; and (v) Mr. Tennant,50,000 PSUs.

Under the terms of the PSUs, the PSUs will vest in two equal 50% installments upon the achievement of two specified operational milestones that occur during the period from the grant date to December 31, 2026 (the date of achievement of each milestone, a “Vesting Date”). Under the trading plans, the Company is authorized to direct the sale of shares upon the occurrence of a Vesting Date, and each plan will terminate 45 days after the last Vesting Date, unless terminated earlier in accordance with the terms of the trading plan. The latest possible termination date under the trading plans is February 14, 2027.
