Insights

Jasper reshapes top leadership, elevating internal talent to CEO.

The company is transitioning from Ron Martell to Jeet Mahal as Chief Executive Officer and President effective January 5, 2026. Martell’s exit is contractually classified as a termination without cause, triggering severance of 18 months of base salary and up to 18 months of COBRA premiums under his employment agreement, which represents a cash outlay but follows pre-agreed terms.

Mahal moves from Chief Operating Officer to Chief Executive Officer and principal executive officer while also joining the Board as a Class III director. His compensation now includes a $600,000 annualized base salary and an annual performance bonus opportunity up to 50% of base salary, with potential for future equity and cash awards at the Compensation Committee’s discretion. The appointment of Board Chair Thomas G. Wiggans as Executive Chair adds an executive governance layer that may influence how responsibilities are shared at the top level, with more detail likely to appear in subsequent proxy or compensation disclosures.
