-- Data Were Presented in an Oral Presentation at the American Thoracic Society (ATS) International Conference 2026 --

Savara Inc. (NASDAQ:SVRA) (the Company), a clinical stage biopharmaceutical company focused on rare respiratory diseases, sponsored an oral presentation at the ATS 2026 International Conference that is taking place May 15-20, 2026, in Orlando, Florida. The presentation reported new exercise capacity data from the double-blind period of the IMPALA-2 Phase 3 clinical trial evaluating molgramostim for the treatment of aPAP.

Below is a summary of the data presented.

Oral Presentation, Abstract 9296: "Molgramostim Improves Exercise Distance and Duration in Patients with Autoimmune Pulmonary Alveolar Proteinosis (aPAP): Results from the IMPALA-2 Phase 3 Clinical Trial," presented by B.C. Trapnell, M.D.; sponsored by Savara Inc.

• Presented exercise capacity data from IMPALA-2, a global, randomized, double-blind, placebo-controlled Phase 3 clinical trial in which adults with aPAP received nebulized molgramostim 300 µg (n=81) or placebo (n=83) once daily for 48 weeks. IMPALA-2 achieved statistical significance on its primary endpoint and other secondary endpoints, including a greater mean improvement in exercise capacity, expressed as peak metabolic equivalents (METs), in the molgramostim group at 48 weeks. This oral presentation reported on the effects of molgramostim on exploratory endpoints of exercise distance and duration, assessed at Weeks 24 and 48 via a conservative, ramp-up, symptom-limited, exercise treadmill test.
• Greater mean improvement in distance walked was observed in molgramostim-treated patients compared with placebo at Week 48. The least-squares mean (LSM) change in distance walked from baseline to Week 48 was 167.0 m (95% confidence interval [CI], 112.1 to 221.8) in the molgramostim group and 86.4 m (95% CI, 32.4 to 140.4) in the placebo group, yielding an estimated treatment difference of 80.6 m (P=0.0301).
• Molgramostim patients were also able to exercise for longer periods of time compared with patients who received placebo. At Week 48, the LSM change in duration of exercise from baseline was 2.0 minutes (95% CI, 1.3 to 2.7) in the molgramostim group and 1.0 minute (95% CI, 0.3 to 1.6) in the placebo group, yielding an estimated treatment difference of 1.0 minute (P=0.0262).
• Consistent with improvements in peak METs, molgramostim improved both distance walked and duration of exercise at Week 48 compared with placebo, supporting the potential clinical benefit of molgramostim treatment in patients with aPAP.
