Rhea AI SLS FY2025

SELLAS is funding a development-stage operation externally: losses remain large, while 2025 financing rebuilt liquidity and reduced leverage.

In FY2025, net loss narrowed to $26.9M from $30.9M in FY2024, indicating some operating improvement. Operating cash outflow also narrowed to $28.4M from $35.4M, keeping cash movement broadly aligned with accounting loss rather than showing a large conversion gap.

The balance sheet changed mainly through financing, not operations: financing cash inflow of $86.3M exceeded operating cash outflow of $28.4M. That funding lifted total assets to $78.3M while liabilities remained only $7.5M, leaving a current ratio of 10.7x and debt-to-equity of 0.1x.

The capital raise came alongside share count nearly doubling from 90.8M in FY2024 to 179.6M in FY2025, while R&D declined from $19.1M to $16.0M. Revenue was $1M in FY2022 and unreported thereafter, so the improved balance sheet reflects external capital and controlled development spending—not a shift to commercial revenue.
