Revelation Biosciences, Inc. Announces Financial Results for the Three and Six Months Ended June 30, 2024

Revelation Biosciences, Inc. (NASDAQ:REVB) (the "Company" or "Revelation"), a clinical-stage biopharmaceutical company focused on harnessing the power of trained immunity for the prevention and treatment of disease by developing and commercializing therapeutics that modulate the innate immune system, today reported its three and six months ended June 30, 2024 financial results.

Corporate Highlights

• Completed dosing of its first in human phase 1 clinical study of Gemini
• Announced positive phase 1 clinical data of Gemini met the primary safety endpoint and showed statistically significant biomarker activity

"The Revelation team has worked hard in the first half of 2024 to continue to build the foundation for successful advancement of Gemini and we were excited to share that the primary endpoint to evaluate the safety and tolerability of escalating doses of Gemini was met, a maximum tolerated dose in healthy volunteers was identified and statistically significant dose dependent upregulation of key biomarkers was observed, demonstrating the immunostimulatory preconditioning effect of Gemini," said James Rolke, Chief Executive Officer of Revelation. "During the second half of 2024, we look forward to building on this momentum with the start of a Phase 1b study in CKD patients."

Results of Operations

As of June 30, 2024, Revelation had $12.1 million in cash and cash equivalents, compared to $12.0 million as of December 31, 2023. 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 2024.

Revelation's net cash used for operating activities for the six months ended June 30, 2024 was $5.3 million compared to net cash used for operating activities of $3.6 million for the same period in 2023. Revelation's net loss for the three months ended June 30, 2024 was $8.4 million, or $5.13 basic and diluted net loss per share compared to a net loss of $1.4 million, or $5.83 basic and diluted net loss per share for the same period in 2023. Revelation's net loss for the six months ended June 30, 2024 was $11.1 million, or $8.13 basic and diluted net loss per share compared to net income of $4.7 million, or $24.52 basic net earnings per share and $23.89 diluted net earnings per share for the same period in 2023, respectively.

About Gemini

Gemini is a proprietary formulation of phosphorylated hexaacyl disaccharide (PHAD®) for systemic administration. It is being developed for multiple indications including as a pretreatment to prevent or reduce the severity and duration of post-surgical infection (GEMINI-PSI program), as pretreatment to prevent or reduce the severity and duration of acute kidney injury (GEMINI-AKI program). In addition, Gemini may be a treatment to stop or slow the progression of chronic kidney disease (GEMINI-CKD program). Revelation believes Gemini works through trained immunity, which redirects and attenuates the innate immune response to external stress (infection, trauma, etc.). Revelation has conducted multiple preclinical studies demonstrating the therapeutic potential of Gemini in the target indications.
