Results of Operations

As of June 30, 2025, Revelation had $5.2 million in cash and cash equivalents, compared to $6.5 million as of December 31, 2024.

Revelation’s net cash used for operating activities for the three months ended June 30, 2025 was $4.7 million compared to net cash used for operating activities of $5.3 million for the same period in 2024. Revelation’s net loss for the three months ended June 30, 2025 was $2.4 million, or $(7.01) basic and diluted net loss per share compared to a net loss of $8.4 million, or $(246.27) basic and diluted net loss per share for the same period in 2024.

About Gemini

Gemini is an intravenously administered, proprietary formulation of phosphorylated hexaacyl disaccharide (PHAD^®) that reduces the damage associated with inflammation by reprogramming the innate immune system to respond to stress (trauma, infection, etc.) in an attenuated manner.

Gemini is being developed for multiple indications including as a pretreatment to prevent or reduce the severity and duration of acute kidney injury (GEMINI-AKI program), and as pretreatment to prevent or reduce the severity and duration of post-surgical infection (GEMINI-PSI program), or infection post severe burn (GEMINI-PBI). Gemini may also be a treatment to stop or slow the progression of chronic kidney disease (GEMINI-CKD program).

Revelation has conducted multiple preclinical studies demonstrating the therapeutic potential of Gemini in the target indications. Revelation previously announced positive Phase 1 clinical data for intravenous treatment with Gemini: the primary safety endpoint was met in the Phase 1 study, and results demonstrated statistically significant pharmacodynamic activity, as observed through expected changes in multiple biomarkers including upregulation of IL-10.
