Conference call and webcast to be held on Wednesday, May 13, 2026 at 4:30 pm ET

SAN MATEO, Calif., May 13, 2026 /PRNewswire/ -- Talphera, Inc. (Nasdaq: TLPH), ("Talphera"), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in medically supervised settings, today announced first quarter 2026 financial results and provided a corporate update.

"In early March, we announced the attainment of 50% enrollment in the NEPHRO CRRT study evaluating nafamostat. With continued steady enrollment, we have well exceeded this level, and continue to expect study completion later this year," stated Vince Angotti, CEO of Talphera.  "Our clinical study sites and principal investigators remain focused on enrollment and delivering a high quality study as they are eager for a potential alternative anticoagulant for Continuous Renal Replacement Therapy (CRRT). The investor and analyst event held in March also highlighted the need for an alternative, given the disadvantages of the currently used products, heparin and citrate.  If approved, we continue to believe nafamostat will fill an unmet need in the market as a regional anticoagulant for CRRT," continued Angotti.

First Quarter 2026 and Recent Highlights

• In March 2026, announced reaching the 35-patient enrollment milestone, representing 50% enrollment in the NEPHRO CRRT study. Enrollment has continued to increase since this announcement, with study completion expected in 2026.
• In March 2026, held an investor and analyst event with two key opinion leaders (KOLs) focused on anticoagulants used during CRRT and the potential for nafamostat to address an unmet need.
• In March 2026, two posters were presented at the 31^st Annual International Conference on Advances in Critical Care Nephrology (AKI & CRRT 2026), entitled: "A Randomized, Placebo-Controlled Multi-Center Study of the Safety and Efficacy of Niyad in Patients Undergoing Continuous Renal Replacement Therapy Who Cannot Tolerate Heparin or Are at a Higher Risk of Bleeding" and, "In Vivo Assessment of Nafamostat, A Novel Regional Anticoagulant in a Porcine Model AKI and CKRT".
• In March 2026, closed $4.1 million third tranche of the March 2025 private placement financing upon achieving the 35-patient enrollment milestone and other conditions.

First Quarter 2026 Financial Information

• The cash and investments balance was $21.1 million as of March 31, 2026.
• Combined R&D and SG&A expenses for the first quarter of 2026 totaled $3.9 million compared to $2.9 million for the first quarter of 2025. Excluding non-cash stock-based compensation expense, these amounts were $3.7 million for the first quarter of 2026, compared to $2.7 million for the first quarter of 2025. The increase in combined R&D and SG&A expenses in the first quarter of 2026 was primarily due to higher Niyad® development expenses, reflecting increased enrollment, and an increase in certain G&A expenses.
• Net loss attributable to common shareholders for the first quarter of 2026 was $2.6 million, or $0.04 per basic and diluted share, compared to a net loss of $2.6 million, or $0.10 per basic and diluted share, for the first quarter of 2025.
