Rhea AI PTGX FY2025

Revenue recognition shifted sharply: a one-year earnings spike gave way to development spending, yet FY2025 cash flow remained positive.

FY2025 paired a -$130.1M net loss with $57.7M of operating cash flow and $56.1M of free cash flow, reversing the cash losses recorded through FY2023. That gap means reported earnings were heavily affected by non-cash items or operating balance-sheet movements, so accounting loss did not equal cash consumption in the year.

The operating model remains development-stage in scale: FY2025 research and development reached $159.3M against $46.0M of revenue, while FY2024 had produced $275.2M of net income on $434.4M of revenue. The swing suggests reported revenue and earnings are uneven rather than evidence of a stable commercial base.

The balance sheet is lightly leveraged: FY2025 liabilities were $53.5M against $668.2M of assets, with a 12.7x current ratio and 0.1x debt-to-equity. Shares outstanding also rose from 58.3M to 63.8M across FY2023-FY2025, consistent with external equity financing remaining part of the funding model.

Protagonist Ther (PTGX) has a Piotroski F-Score of 3 out of 7 computable signals; 2 of the nine could not be computed from available data, so the full-scale strength rating is not shown. The F-Score evaluates nine binary signals across profitability (positive ROA, positive cash flow, improving ROA, earnings quality), leverage (decreasing debt, improving liquidity, no share dilution), and operating efficiency (improving gross margin, improving asset turnover). Scores of 7 to 9 indicate strong and improving fundamentals. Learn more in our complete guide to financial health indicators.

Protagonist Ther (PTGX) reported a net loss of $130.1M while generating $57.7M in operating cash flow. Operations generated cash despite the loss, but with no positive earnings behind it, the ratio between the two carries no quality signal. This ratio compares operating cash flow to net income. A ratio above 1.0x means the company generates more cash than its reported earnings, indicating sustainable, cash-backed profits. Ratios below 1.0x suggest earnings rely on accounting accruals rather than actual cash generation. Learn more in our complete guide to financial health indicators.

Protagonist Ther (PTGX) scores 76 out of 100 on our Financial Health Score, indicating strong standing within its emerging companies peer group. The score is a 0-100 composite of six dimensions (Cash Runway, Dilution, R&D Intensity, Revenue Progress, Burn Trend, Balance Sheet), each ranked as a percentile relative to companies in the same scoring family (banks against banks, REITs against REITs, and so on) rather than across all industries. It rates the quality of the business, not whether the stock is fairly priced, and is not financial advice. Learn more in our complete guide to financial health indicators.
