Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On August 17, 2026, Diego Reynoso informed the Company that he was stepping down as the Company’s Treasurer and Chief Financial Officer. His departure from the Company is not related to any disagreement with the Company on any matter relating to its operations, policies, or practices. To support an orderly transition, Mr. Reynoso will remain at the Company through September 30, 2026. The Company’s Board of Directors has launched a formal search process to identify Mr. Reynoso’s permanent replacement.

On August 20, 2026, the Company’s Board of Directors approved the appointment of Matthew D. Murphy, age 57, to serve as interim Treasurer and Chief Financial Officer, effective September 15, 2026, and until such time as the Company appoints Mr. Reynoso’s permanent successor. Mr. Murphy is currently the Chief Accounting Officer and Vice President of Finance of the Company. He has held the titles of Chief Accounting Officer since 2015 and Vice President of Finance since 2023. He also previously held the position of Interim Treasurer and Chief Financial Officer from March 2023 to September 2023. Prior to his current role, he was the Company’s Corporate Controller from September 2006 to August 2015.

On August 20, 2026, Mr. Murphy and the Company entered into an Offer Letter outlining the details of Mr. Murphy’s compensation in his new role of Chief Accounting Officer, Interim Chief Financial Officer & Interim Treasurer. A copy of the Offer Letter is attached hereto as Exhibit 10.1. The terms of the Offer Letter were approved by the Compensation Committee on August 20, 2026.

Mr. Murphy’s annual base salary will be $419,359.41, unchanged from his previous base salary. His bonus potential will be determined by the Company’s performance against its “Bonus Scale”, which is described in the Form 8-K filed by the Company on February 17, 2026. If the Company achieves the 100% payout level on the Scale, Mr. Murphy’s bonus will be 50% of his base salary, no change from his prior bonus target.

Mr. Murphy will continue to be eligible to receive equity through the Company’s Long-Term Equity program, subject to approval by the Board of Directors. While equity is not guaranteed, the target annual value of Mr. Murphy’s equity awards is $250,000, no change from his previous target.

Additionally, the Company agreed to grant Mr. Murphy a cash bonus of up to $700,000, payable in four installments, the first of which will be payable on December 31, 2026, and the fourth on March 1, 2028, with payment of each installment contingent upon continued employment with the Company, except as otherwise provided in the Offer Letter. The full details of the cash bonus are outlined under the heading “Interim CFO Transition Bonus” in the Offer Letter.

There is no arrangement or understanding with any person pursuant to which Mr. Murphy is being elected as Interim Chief Financial Officer & Interim Treasurer. There are no family relationships between Mr. Murphy and any director or executive officer of the Company, and he is not a party to any transaction requiring disclosure under Item 404(a) of Regulation S-K.
