THIRD QUARTER 2024 FINANCIAL RESULTS:

Cash and Cash Equivalents

Cash and cash equivalents were $188.2 million as of September 30, 2024, as compared to $99.8 million as of December 31, 2023. Zura Bio anticipates that its existing cash and cash equivalents and investments should be sufficient to support operations as currently planned through 2027.

Operating Results

Research and development expenses were $6.0 million for the third quarter of 2024, an increase of $2.0 million compared to $4.0 million for the same period in 2023. The increase was primarily due to an increase of $1.7 million in personnel compensation for research and development functions including share-based compensation and an increase of $0.9 million for consulting services costs for preparation of clinical trials, partially offset by a decrease of $0.7 million in manufacturing costs.

General and Administrative expenses were $13.3 million for the third quarter of 2024, an increase of $7.1 million compared to $6.2 million for the same period in 2023. The increase was primarily due to $5.3 million in share-based compensation, driven by a one-time non-cash expense, as well as $1.6 million in fees related to the warrant exchange.

Net Loss

Net loss for the third quarter of 2024 was $22.9 million or $0.26 per share compared to $8.3 million or $0.18 per share for the same period in 2023.
