Virtual investor and analyst day with business updates to be held on Monday, March 23, 2026 at 11:00 am ET

SAN MATEO, Calif., March 23, 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 fourth quarter and full year 2025 financial results and provided a corporate update.

"Earlier this month, we communicated reaching the 35-patient enrollment mark in the 70-patient nafamostat registrational study for CRRT. Since then, we have added two more target profile clinical sites, and are continuing to enroll patients at a pace to enable completion of the study later this year," stated Vince Angotti, CEO of Talphera. "Our target profile clinical sites and principal investigators remain highly motivated, driving over 90% of enrollment to date, and they are excited by the prospect of having nafamostat potentially approved for use during CRRT, given their dissatisfaction with the current anticoagulants currently being used for CRRT. Later today, we are hosting a live virtual investor and analyst webcast where you will hear directly from two principal investigators in the NEPHRO CRRT registrational study and their experiences with CRRT, the currently available anticoagulants for CRRT, and how they see nafamostat potentially filling an unmet need."

Fourth Quarter 2025 and Recent Highlights

• Reached the 35-patient enrollment milestone or 50% enrollment in the NEPHRO CRRT study.
• All 12 clinical sites are now able to enroll patients and are expected to support increased enrollment rates for the remainder of the NEPHRO CRRT clinical study.
• Closed $4.1 million third tranche of the March 2025 private placement financing upon achieving the 35-patient enrollment milestone and other conditions.
• In October 2025, certain purchasers waived the conditions of the securities purchase agreement dated March 31, 2025, to effect both the second and third closings of the private placement with respect to such purchasers only, resulting in aggregate gross proceeds to Talphera of approximately $1.6 million.

Fourth Quarter 2025 Financial Information

• The cash and investments balance was $20.4 million as of December 31, 2025.
• Combined R&D and SG&A expenses for the fourth quarter of 2025 totaled $3.5 million compared to $3.0 million for the fourth quarter of 2024. Excluding non-cash stock-based compensation expense, these amounts were $3.3 million for the fourth quarter of 2025, compared to $2.8 million for the fourth quarter of 2024. The increase in combined R&D and SG&A expenses in the fourth quarter of 2025 was primarily due to increases in costs associated with Niyad development and certain G&A expenses.
• Net loss attributable to common shareholders for the fourth quarter of 2025 was $3.8 million, or $0.06 per basic and diluted share, compared to a net loss of $1.9 million, or $0.07 per basic and diluted share, for the fourth quarter of 2024.

2026 Guidance

• Cash operating expenses, or selling, general and administrative, and research and development expenses, excluding stock-based compensation, are expected to be in the range of $17 million to $18 million in 2026, which includes the expenses related to finalizing the NEPHRO CRRT registration trial later this year. This is an increase from approximately $13 million in 2025, which is driven by the NEPHRO CRRT study and related CMC expenses and validation batches expected to be incurred prior to the filing of a Premarket Approval (PMA) with the FDA.
