Rhea AI PHIO FY2025

Equity raises rather than operations fund the business, with cash reserves rebuilt even as annual burn stayed near $8.0M.

From FY2024 to FY2025, operating cash outflow and free cash flow stayed almost identical at about -$8.0M, while net loss remained in the same range, showing earnings quality is unusually literal: reported losses are largely cash leaving the business. The jump in cash to $21.0M came alongside $23.6M of financing, so the stronger balance sheet was created by fresh capital rather than by the cost structure turning self-funding.

With $21.0M of cash against only $1.3M of total liabilities, this is a liability-light balance sheet with little lender pressure; the practical constraint is cash runway, not debt service.

After shrinking through FY2024, the annual burn moved back up in FY2025 as R&D and SG&A each ran near $4.6M, indicating spending is divided between research effort and corporate overhead rather than dominated by one line. That split suggests the burn comes from the whole operating platform, not a single expense category that could be removed without changing how the business operates.
