Revelation Biosciences Inc. (NASDAQ:REVB) (the "Company" or "Revelation"), a life sciences company that is focused on the development of immunologic based therapies for the prevention and treatment of disease, today reported its three months ended March 31, 2023 financial results and highlighted recent corporate progress.

Corporate Highlights

• Established strong scientific advisory team with extensive preclinical experience using PHAD to prevent disease.
• Initiated additional nonclinical studies to further study PHAD in treatment and prevention of CKD and AKI in order to inform future clinical study designs in patients.
• IND and clinical enabling studies under way for anticipated Phase 1 clinical study starting in Q4 2023.

"We are off to a great start for 2023 and have commenced our IND and clinical study enabling activities to advance REVTx-300 and REVTx-100," said James Rolke, Chief Executive Officer of Revelation. "We are laser-focused and on track to file our IND and initiate clinical studies of REVTx-300 and REVTx-100 in Q4 of this year."

Results of Operations

As of March 31, 2023, Revelation had $17.7 million in cash and cash equivalents, compared to $5.3 million as of December 31, 2022. The increase in cash and cash equivalents was primarily due to net cash received from financing activities, offset primarily by cash used for operating activities. Based on current operating plans and projections, Revelation believes that its current cash and cash equivalents are sufficient to fund operations through June of 2024.

Revelation's net cash used for operating activities for the three months ended March 31, 2023 was $1.6 million compared to net cash used for operating activities of $4.8 million for the same period in 2022. Revelation's net income for the three months ended March 31, 2023 was $6.2 million, or $2.79 basic earnings per share and $1.96 diluted earnings per share, compared to a net loss of $6.6 million, or $15.09 basic and diluted loss per share for the same periods in 2022.

Net income was primarily due to the change in fair value of the warrant liability creating a $7.7 million gain. The changes in net cash used for operating activities and the decrease in net loss in 2023 as compared to 2022 were primarily due to decreases clinical study expenses associated with our Phase 2b viral challenge clinical study (REVTx-99a) and our Phase 1b allergen challenge study (REVTx-99b), legal fees, professional consulting service fees and public company directors and officers insurance policy.
