Centessa Pharmaceuticals Stock Slides as Leadership Transition Announced

Centessa Pharmaceuticals plc (CNTA) shares dropped 5.34% in pre-market trading on Nasdaq, settling at $27.99, as the clinical-stage pharmaceutical firm disclosed significant leadership changes. The decline follows the company's Thursday announcement regarding its executive restructuring.

The pharmaceutical company confirmed that Saurabh Saha, who currently serves as chief executive officer, will relinquish his position effective January 1, 2026. Mario Accardi has been designated as his successor and will assume the CEO role on the same date, marking a transition in the company's top leadership.

Accardi brings notable industry experience to the role. Before joining Centessa Pharmaceuticals, he founded and led Orexia Therapeutics, a neuroscience-focused pharmaceutical company. His background in the therapeutic space positions him to navigate Centessa's clinical development pipeline as the firm progresses through its pharmaceutical initiatives.

The leadership change reflects evolving strategic directions within the organization, with Saha stepping aside after his tenure leading the clinical-stage biotech company. The transition to Accardi's leadership takes effect on January 1, 2026, providing a structured timeline for the management shift.
