A10 Networks Appoints New Director, Expands Board to Six

What Happened

• A10 Networks, Inc. filed an 8-K (Item 5.02) announcing that its Board approved increasing the board size from five to six members and appointed Mary C. Henry as a director. The Board approved the change on September 9, 2026, and Ms. Henry’s appointment is effective October 5, 2026, through the Company’s 2027 Annual Meeting of Stockholders (or until her successor is elected or earlier departure).

Key Details

• Board size increased from 5 to 6 members; Mary C. Henry appointed as the new director.
• Appointment approved Sept 9, 2026; effective Oct 5, 2026; term runs until the 2027 Annual Meeting.
• Ms. Henry has not yet been assigned to any board committees.
• She will receive the Company’s standard non-employee director compensation and will sign the Company’s standard indemnification agreement; no related-party transactions or special arrangements were reported.

Why It Matters

• Board composition changes can affect governance and strategic oversight; investors should note the added director and the schedule for committee assignments.
• The filing indicates this is a routine, non-compensatory appointment under existing director pay and indemnification terms, with no disclosed related-party transactions—suggesting a standard governance update rather than a material corporate change.
