The derivative option position was reduced by 350,000 shares, leaving 525,000 options outstanding after the transaction.

Akebia Therapeutics, Inc. reported for the quarter ended June 30, 2026 total revenues of $49.1 million, compared with $62.5 million a year earlier, including product revenue of $46.8 million. Higher research and development, selling, general and administrative, and restructuring costs lifted total operating expenses to $45.0 million, resulting in a loss from operations of $6.3 million. After interest and other items, Akebia recorded a net loss of $8.9 million, or $0.03 per basic and diluted share, versus modest net income in the prior-year quarter.
As of June 30, 2026, the company held $155.5 million in cash and cash equivalents and total assets of $349.7 million, against total liabilities of $324.6 million, including a $49.6 million senior secured term loan and substantial royalty-related liabilities tied to Vafseo and Auryxia. Stockholders’ equity was $25.0 million. Akebia markets Vafseo for anemia due to chronic kidney disease and Auryxia for CKD-related indications; Auryxia lost U.S. exclusivity in March 2025, and a Teva generic entered in March 2026. Management expects existing cash and anticipated product, royalty, supply and license revenues to fund its current operating plan for at least twelve months, while acknowledging that refinancing its term loan and achieving projected Vafseo revenues are important to longer-term liquidity and that additional financing or strategic transactions may be pursued.
Akebia Therapeutics reported second quarter 2026 results with total revenues of $49.1 million, down from $62.5 million a year earlier, as Auryxia sales declined due to generic competition. Vafseo net product revenue increased to $21.3 million from $13.3 million, while Auryxia revenue fell to $25.5 million from $47.2 million. The company recorded a net loss of $8.9 million, compared with net income of $0.2 million in the prior-year quarter. Cash and cash equivalents were $155.5 million as of June 30, 2026.
Commercially, more than 10,500 patients were on Vafseo in the quarter, with prescribers rising to about 1,200.

Akebia also initiated a Phase 2 open-label basket trial of ebribafusp for several rare kidney diseases, continued enrolling a Phase 2 trial of praliciguat in FSGS, and strengthened Vafseo’s patent estate with a new Orange Book–listed patent and potential patent term extension. Operating expenses included $1.9 million of restructuring charges related to commercial reorganization.
