On July 22, 2025, the Board adopted a resolution pursuant to Section 3.03 of Article III of the Company's Amended and Restated By-Laws (the "By-Laws") to set the number of directors constituting the Board at nine and elected Thomas C.

The RSUs will vest over three years in equal annual installments on the first three anniversaries of July 22, 2025, provided that Mr. Naratil or Ms. Risi, as the case may be, is serving as a director of the Company on such date.

Mr. Naratil and Ms. Risi will receive compensation for their service as director consistent with that of the Company's other non-employee directors, as described in the Company's definitive proxy statement filed with the U.S. Securities and Exchange Commission on April 14, 2025.
