Blaize Holdings taps former BOXABL CFO Martin Costas to lead operations and finance, succeeding Harminder Sehmi in a planned transition to strengthen the company's capital management.
The company announced on November 5, 2026 that Martin Costas becomes COO and CFO effective November 2, 2026, succeeding retiring Harminder Sehmi after an orderly Board-led search. The new CFO brings over 25 years of public-company finance experience, including the CFO role at BOXABL during its Nasdaq listing. Leadership changes without financial figures typically have limited price impact; the focus on financial discipline could be mildly positive but is unquantified.
Martin Costas was appointed Chief Operations Officer and Chief Financial Officer, effective November 2, 2026. He previously served as CFO of BOXABL, Honeywell Process Solutions and Nexans AmerCable.
Harminder Sehmi is retiring to pursue other interests; the company said planning for his retirement began in the summer of 2026 and he will stay through November 30, 2026 to support the transition.
