Rhea AI ZSTK FY2025

Near-flat sales now sit atop very thin gross margins, while 2025 financing and reported losses reshaped the balance sheet.

Revenue was nearly unchanged between FY2024 and FY2025, yet gross margin compressed from 6.1% to 4.6%; the business therefore had less gross profit available to absorb overhead. That margin squeeze coincided with an operating loss of $154.7M, revealing a cost structure not scaled to the sales base.

The operating loss reached $154.7M in FY2025 even as revenue was $35.7M, indicating that reported operating costs vastly exceeded what the gross-profit pool could fund. Long-term debt of $50.8M appeared alongside a 1.0x current ratio, shifting the balance sheet toward financing dependence with little short-term cushion.

A net loss of $119.7M was much larger than operating cash outflow of $8.7M, so accounting earnings and cash consumption diverged sharply; the gap suggests substantial noncash or non-operating effects in the reported loss. Free cash flow nearly matched operating cash flow because capital expenditures were only $127K, indicating the cash shortfall was primarily operational rather than reinvestment-heavy.
