FULL YEAR 2024 FINANCIAL RESULTS

Cash Position

Cash and cash equivalents were $176.5 million as of December 31, 2024, as compared to $99.8 million as of December 31, 2023. Zura Bio anticipates that its existing cash and cash equivalents should be sufficient to support operations as currently planned through 2027.

Research and development expenses were $24.4 million for the year ended December 31, 2024, a decrease of $19.6 million compared to $44.0 million for the year ended December 31, 2023. The decrease was primarily due to $27.2 million related to the acquisition of tibulizumab from Eli Lilly and Company ("Lilly") during the year ended December 31, 2023. This decrease was partially offset by a $4.5 million milestone payment in 2024 related to the Lilly license for tibulizumab and an increase of $2.9 million for cash-based compensation expenses for personnel in R&D functions and an increase of $2.0 million of costs incurred for consulting services for our product candidates.

General and administrative expenses were $30.8 million for the year ended December 31, 2024, an increase of $12.2 million compared to $18.6 million for the year ended December 31, 2023. The increase was primarily due to $8.3 million in compensation costs, including a one-time non-cash stock-based compensation expense of $5.9 million and a $2.4 million increase in cash and non-cash compensation costs for personnel in executive and administrative functions, as well as a $2.9 million increase in professional fees, driven by $1.6 million in fees related to the warrant exchange.

Net Loss

Net Loss was $45.4 million or $0.60 per share for the year ended December 31, 2024, compared to $69.2 million or $2.09 per share for the year ended December 31, 2023.
