ARCA biopharma Announces Third Quarter 2023 Financial Results

------------------------------------------------------------------------------------------------------------

•Company is currently engaged in a strategic review process, evaluating additional development of its assets, collaborations and other strategic options

Westminster, CO, October 18, 2023 –ARCA biopharma, Inc. (Nasdaq: ABIO), a biopharmaceutical company applying a precision medicine approach to developing genetically targeted therapies for cardiovascular diseases, today reported third quarter 2023 financial results and provided a corporate update.

In April 2022, the Board of Directors established a Special Committee and, in May 2022, retained Ladenburg Thalmann & Co. Inc. (“Ladenburg”) to evaluate strategic options, including transactions involving a merger, sale of all or part of the Company’s assets, or other alternatives with the goal of maximizing stockholder value. The Company and Ladenburg have reviewed several potential strategic transactions and continue to evaluate further potential development of the Company’s existing assets, in order to maximize stockholder value. The Company does not have a defined timeline for the strategic review process and the review may not result in any specific action or transaction.

Third Quarter 2023 Summary Financial Results

Cash and cash equivalents were $38.5 million as of September 30, 2023, compared to $42.4 million as of December 31, 2022. ARCA believes that its current cash and cash equivalents, consisting primarily of money market funds, will be sufficient to fund its operations through the end of 2024.

General and administrative (G&A) expenses were $1.6 million for the quarter ended September 30, 2023, consistent with $1.5 million for the corresponding period in 2022. G&A expenses in 2023 are expected to be consistent with those in 2022 as the Company maintains administrative activities to support our ongoing operations.

Research and development (R&D) expenses were $0.3 million for the quarter ended September 30, 2023, compared to $1.0 million for the corresponding period in 2022, a $0.7 million decrease. R&D personnel costs decreased approximately $0.6 million for the quarter ended September 30, 2023, as compared to the corresponding period in 2022, due to decreased headcount. In July 2022, we implemented a strategic reduction of our workforce by approximately 67%, or 12 employees. Personnel reductions were primarily focused in research and development and general and administrative functions. The restructuring was a result of our decision to manage our operating costs and expenses. During the nine months ended September 30, 2022, we recorded total restructuring charges of approximately $790,000, of which $490,000 and $300,000 were recognized in research and development and general and administrative expenses, respectively, in

connection with the restructuring, all in the form of one-time termination benefits. R&D expenses in 2023 are expected to be lower than 2022.

Total operating expenses for the quarter ended September 30, 2023 were $2.0 million compared to $2.6 million for the third quarter 2022.

Net loss for the quarter ended September 30, 2023 was $1.4 million, or $0.10 per basic and diluted share, compared to $2.3 million, or $0.16 per basic and diluted share in the third quarter of 2022.
