3Forward Guidance and Outlook

Vafseo Growth: Anticipated continued growth in 2026, particularly as more dialysis organizations adopt observed dosing protocols. The company expects significant revenue growth, especially from organizations implementing these protocols.

Auryxia Revenue Decline: Expected to continue decreasing throughout 2026 due to increased generic competition.

Cash Position: Management believes current cash resources will sustain operations for at least two years.

4Bad News, Challenges, or Points of Concern

Declining Auryxia Revenues: The company faces challenges with Auryxia due to pricing pressures and competition from generics, leading to a forecasted decline in revenues.

Net Loss: Transition from profit to loss raises concerns about financial sustainability, particularly with increased expenses in R&D and SG&A.

Market Competition: The entry of new treatments for kidney diseases, such as sparsentan for FSGS, poses competitive pressures that could impact enrollment and market share for Akebia's pipeline products.

5Notable Q&A Insights

Patient Growth: The increase in patients on Vafseo was broad-based across dialysis organizations, with USRC showing significant growth due to the transition to observed dosing protocols.

Enrollment Dynamics: The approval of competing products like Filspari is not expected to significantly impact enrollment for praliciguat trials, as many patients will still require additional treatment options.

Adherence Rates: First refill adherence for patients on observed dosing protocols is at 86%, which is expected to remain stable as more organizations adopt these protocols.

Future Growth: The growth trajectory for Vafseo is uncertain, with potential for acceleration dependent on DaVita's adoption of observed dosing protocols later in the year. Overall, Akebia's Q1 2026 results reflect a strong start for Vafseo amidst challenges with Auryxia and increasing competition in the kidney disease market. The company remains focused on expanding its presence and establishing Vafseo as a standard treatment option.
