Rhea AI SONN FY2025

FY2025 was a balance-sheet reset funded externally, while the core business still operated as a cash-burning development program.

From FY2024 to FY2025, solvency improved because capital was raised, not because operations turned. A $26.0M financing inflow lifted cash to $5.1M even as both net loss and operating cash flow stayed deeply negative, so the healthier current ratio reflects recapitalization more than self-funding.

Even with FY2025 revenue at $1.0M, this still reads as a development-stage cost structure. R&D consumed $8.4M and SG&A another $8.5M, so spending level—not commercial scale—still defines how the company operates and why reported sales say little about its economic model.

Losses were also fairly cash-real: FY2025 net loss of -$16.0M sat close to operating cash burn of -$12.8M. With year-end cash of $5.1M, the company held only about 0.4x of one year’s burn, which helps explain its reliance on external financing rather than debt-funded expansion or internally generated liquidity.
