On August 10, 2026, Adtran Networks — the majority-owned subsidiary of ADTRAN Holdings — amended CTO Christoph Glingener's employment agreement, extending his term through December 31, 2026 at an unchanged €400,000 base salary. He remains eligible for an annual cash bonus targeted at 60% of salary, time-based RSUs targeted at 75% of salary (capped at €903,729), and a three-year financial-plan PSU award with a €903,729 target and a €2,000,000 cap. The amendment also keeps his total annual remuneration capped at €2,800,000 and notes the company will not award market-based PSUs tied to relative TSR to named executive officers going forward. The time-based RSU and long-term financial-plan PSU grants were approved and issued on August 10.
