Protagonist Therapeutics, Inc (PTGX) reported $282.0M in revenue over the twelve months to Jun 30, 2026, up 34.8% from the prior twelve months. This page shows its income statement, balance sheet, cash flow statement, and key financial ratios. View 12 years of annual fundamentals and quarterly data, with year-over-year growth rates and compound annual growth rates (CAGR). All figures are derived from SEC filings (10-K and 10-Q reports).
The business shifted from FY2024 profit to FY2025 development-stage economics, yet cash flow remained positive.
FY2024 operating cash flow equaled66.9% of net income, whereas FY2025 produced positive operating cash flow despite a net loss, so cash conversion changed character rather than simply weakening. With R&D at346.2% of revenue, the reported loss is not a direct proxy for cash use in this development cycle.
