On September 2, 2025, Brian Becker resigned as the Chief Financial Officer of A10 Networks, Inc., (the “Company”) and director of various A10 foreign entities, effective September 30, 2025. Mr. Becker has agreed to remain with the Company to assist in transition matters, and no disruption to current operations or outlook is expected as a result of Mr. Becker’s resignation.

On September 5, 2025, the Company announced that Michelle Caron, age 58, had been appointed as Chief Financial Officer, effective September 24, 2025. Prior to joining the Company, Ms. Caron worked for Beckman Coulter Life Sciences, a division of Danaher Corporation, as its Vice President, Finance and Chief Financial Officer beginning in June 2021. Prior to that, she served as Group Financial Officer of Pall Corporation, a subsidiary of Danaher Corporation, from August 2019 to June 2021 and Chief Financial Officer of Phenomenex, a subsidiary of Danaher Corporation, from November 2016 to August 2019. There are no family relationships between Ms. Caron and any director, executive officer or person nominated by the Company to become director or executive officer, and there are no transactions between Ms. Caron or any of her immediate family members, on the one hand, and the Company or any of its subsidiaries, on the other, that would be required to be reported under Item 404(a) of Regulation S-K.

In connection with her appointment, Ms. Caron entered into an offer letter providing for an annual base salary of $400,000, a signing bonus of $150,000 and eligibility to receive an annual performance-based bonus with a target of 50% of base salary pursuant to the A10 Executive Cash Incentive Plan. Additionally, the offer letter provides that management will recommend to the Company’s Board of Directors that she be granted an award of a number of restricted stock units in the value of $250,000, vesting annually over 4 years in equal increments, and an award of a number of performance-based restricted stock units in the value of $250,000, vesting in tranches upon the achievement of a certain trailing 100 calendar day VWAP during a four-year performance period, or earlier in connection with a change in control. Ms. Caron will also be eligible for the Company’s standard executive change in control severance benefits package.

A copy of the press release announcing this executive transition is attached as Exhibit 99.1 to this Current Report on Form 8-K.
