Insights

Corporate governance and executive compensation analyst

OpGen installs a new CEO with performance-linked pay and prior group experience.

OpGen has transitioned its Chief Executive Officer role from John Tan Honjian, who remains Chairman, to Christian-Laurent Bonte. This maintains board continuity while shifting day-to-day leadership to an executive already associated with the group through CapForce International Holdings Ltd, the company’s wholly owned subsidiary.

The compensation structure in Mr. Bonte’s promotion letter is heavily performance-oriented. Alongside a base salary of $156,000 and a guaranteed first-year bonus of $13,000, he can earn a performance bonus between $26,000 and $312,000, plus per-deal incentives and an annual stock grant targeted at $200,000 subject to performance. This mix emphasizes variable and equity-linked pay, aligning a significant portion of his potential compensation with business outcomes.

His employment can be terminated by CapForce on one month’s written notice, which provides contractual flexibility for the company. The disclosure also notes no family relationships with other directors or executives and no other material related-party transactions beyond the promotion letter, underscoring standard governance representations around his appointment.
