Rhea AI XLO FY2025

External financing and a sharp drop in cash burn became the dominant mechanic behind Xilio’s FY2025 balance-sheet reset.

By FY2025, operating cash burn had fallen to -$5.0M from roughly -$69M two years earlier, a much bigger improvement than the loss line alone implies. Cash still rose to $137.5M because financing inflows added $87.8M; with free cash flow nearly matching operating cash flow, this is an operating-spend business whose cash needs come mainly from research and overhead rather than capital equipment.

R&D spending remained above revenue in FY2025, at $56.0M versus $43.8M, so the larger top line reduced cash pressure without yet covering the core research engine. That matters because the business is still organized around funding development work first and treating reported revenue as a partial offset, not a full operating base.

The balance sheet is liquid in the short term: current assets covered current liabilities by 2.6x. But it is also thinly capitalized, with equity of only $35.3M against total liabilities of $119.4M, so the near-term cushion comes from cash on hand and recent capital raising rather than accumulated profits.
