On September 19, 2026, Todd M.

Mr. Cello has agreed to continue to provide transition services to the Company through March 1, 2027 (the “Transition Period”). Mr. Cello’s resignation is not related to a disagreement with the Company on any matter relating to the Company’s operations, policies or practices.

The Company will conduct a comprehensive search for Mr. Cello’s replacement. If the Company has not hired a replacement Chief Financial Officer by the Transition Date, the Board of Directors of the Company is expected to appoint an interim Chief Financial Officer until such time as a successor is appointed.

In connection with Mr. Cello’s transition, the Company entered into a Transition and Separation Agreement with Mr. Cello dated as of September 23, 2026 (the “Transition Agreement”). Pursuant to the Transition Agreement, subject to Mr. Cello’s continued employment with the Company, he will be eligible for his existing base salary through March 1, 2027, and his benefits until March 31, 2027.

During the Transition Period, Mr. Cello will provide transition services in his area of expertise and such other responsibilities as reasonably assigned by the Company’s Chief Executive Officer.
