Rhea AI ARDX FY2025

Ardelyx’s high-gross-margin model is scaling, but commercial expansion and rising debt costs are still consuming the payoff.

By FY2025, revenue reached $407.3M while free cash burn narrowed to -$44.0M. Because gross margin stayed above 85.0% across the last three years but interest expense and operating costs kept climbing, the business appears to have attractive unit economics that are still being intentionally reinvested rather than converted into earnings.

The income statement shape matters more than the headline loss: FY2025 gross margin was 90.3% while operating loss was -$41.0M. That gap suggests the constraint is not production cost, but the selling organization and research budget needed to support adoption and development.

The balance sheet is liquid but more leveraged: a current ratio of 4.3x sits beside debt-funded runway, with debt-to-equity at 1.2x. Cash of $68.0M is only modestly above recent annual free cash burn, and rising inventory and receivables show that more cash is being tied up as the commercial footprint expands.

0.40

Ardelyx scores 0.40, below the 1.81 distress threshold. The score is driven primarily by a large market capitalization ($1.0B) relative to total liabilities ($334.7M). This indicates elevated financial distress risk and warrants close attention to liquidity and debt levels.

Earnings Quality No Cash Backing
N/A

Interest Coverage At Risk
