Second Quarter 2021 Financial Results

Cash Position: Cash and cash equivalents were $613.8 million as of June 30, 2021, compared to $7.2 million for the Centessa Predecessor Group (comprised of Z Factor Limited, LockBody Therapeutics Ltd, and Morphogen-IX Limited, three of the Centessa Subsidiaries acquired in January 2021) as of December 31, 2020. The increase in cash resulted from $344.1 million in net proceeds from the Company’s initial public offering completed in June 2021, and the full exercise of the underwriters’ option to purchase additional shares, $241.6 million in net proceeds from the Company’s Series A financing completed in January 2021, and cash contributed upon the acquisition of the additional Centessa Subsidiaries, net of cash used during the period. Based on the current, non-risk-adjusted operating plan, the Company expects the cash and cash equivalents as of June 30, 2021, to fund its operations until the end of 2023.

Research & Development (R&D) Expenses: R&D expenses for the Company for the three months ended June 30, 2021, were $18.1 million, compared to $1.9 million for the Centessa Predecessor Group during the three months ended June 30, 2020. The $16.2 million increase is primarily attributable to the growth in the portfolio of product candidates under development following the acquisition of the Centessa Subsidiaries in January 2021, as well as increased spending in the Centessa Predecessor Group.

General & Administrative (G&A) Expenses: G&A expenses for the Company for the three months ended June 30, 2021. were $11.8 million, compared to $0.3 million for the Centessa Predecessor Group during the three months ended June 30, 2020. The $11.5 million increase is primarily attributable to public company costs, the operating costs of Centessa Pharmaceuticals plc and Centessa Pharmaceutical Inc. including professional fees, personnel costs and share-based compensation expense, and the increase in operating costs resulting from the acquired Centessa Subsidiaries.

Change in Fair Value of Contingent Value Rights (CVR): The Company recognized a charge of $11.3 million for the three months ended June 30, 2021, compared to $0.0 million for the three months ended June 30, 2020. The CVR, issued at the time of the acquisition, represents future payments (that will be satisfied through the issuance of Centessa shares) that are contingent upon the dosing of the first patient in a registrational Phase 3 study of Palladio Biosciences’ lixivaptan. The fair value is based on the cumulative probability of achieving this milestone, which increased during the period resulting in the charge.

Net Loss: Net Loss attributable to common stockholders for the quarter ended June 30, 2021, was $41.5 million, or $0.65 per share, compared to a net loss of $2.2 million for the Centessa Predecessor Group for the quarter ended June 30, 2020.
