Rhea AI RLYB FY2025

Rallybio remains development-stage: lower research spending is narrowing losses, while investing inflows—not revenue—support its cash position.

Cash conversion remains weaker than accounting results: FY2025 reported a net loss of $9.0M but operating cash outflow of $29.8M, showing that the reported loss understated the period’s cash requirement. At the same time, investing cash inflows of $47.3M exceeded that operating outflow, so the cash pattern depended on investing activity rather than internally generated operations.

Expense reduction, not commercial scale, drove the improvement. Research and development fell to $19.6M in FY2025 from $41.5M in FY2024, helping operating loss narrow to $33.1M; revenue of only $858K remains small relative to that cost base.

The balance sheet is lightly burdened by liabilities: FY2025 liabilities were $4.3M against $62.3M of assets, while the current ratio was 14.5x. Reported liquidity equaled 22 months of the latest annual operating outflow, but the company still relied on investing inflows because operating cash flow remained negative.
