$17 million in proceeds at first closing with the potential to receive an additional $12 million across one additional tranche upon the achievement of the primary endpoint in the NEPHRO clinical study

The completion of this financing is expected to provide the company with sufficient capital through the planned approval of a Niyad PMA in the second half of 2026

SAN MATEO, Calif., Sept. 8, 2025 /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 it has entered into securities purchase agreements with CorMedix Inc. and certain institutional investors for the sale and issuance of shares of common stock and pre-funded warrants in lieu of shares to purchase common stock in a private placement for total potential proceeds of up to $29 million. CorMedix is making a strategic investment in Talphera common stock priced at the market, while the institutional investors will purchase common stock and pre-funded warrants in lieu thereof, priced at the market, in an initial closing and with an additional tranche of $12 million upon achievement of the primary endpoint in the NEPHRO CRRT study, and the company's stock trading at a minimum agreed price.

"We are pleased we have secured funding that provides us with the opportunity to be fully funded through a potential approval of the Niyad PMA, which is anticipated in the second-half of next year," stated Vince Angotti, Talphera CEO. "The strong interest in this financing, particularly from CorMedix, who recognizes the potential value of Niyad in the acute care market, as well as our existing and new institutional investors, further enforces our strong belief that nafamostat is a valuable product for physicians as they currently have no ideal options for anticoagulation for CRRT. If approved, Niyad would become the first available FDA-approved regional anticoagulant for CRRT. Furthermore, the accelerated momentum in enrollment in our NEPHRO CRRT clinical study provides continued confidence in our goal to complete the study by the end of the year," continued Angotti.

The Private Placement

The private placement is led by CorMedix Inc (Nasdaq: CRMD), a commercial stage pharmaceutical company focused on developing and commercializing therapeutic products for life-threatening diseases and conditions, and includes institutional investors Nantahala Capital, Rosalind Advisors, and Rock Springs Capital, and has the potential to raise gross proceeds of up to $29 million, which amount includes (i) $17 million in the first closing (which is expected to occur on September 10, 2025), (ii) $12 million in a second closing with such institutional investors upon the achievement of the primary endpoint in the Company's NEPHRO CCRT study (the "Milestone Event"), and a minimum stock price of at least $0.6875 per share for five consecutive days following a public announcement of the achievement of the Milestone Event.

In the first closing, Talphera will issue 25,036,363 shares of common stock and 5,845,455 pre-funded warrants, at a price of $0.55 per share and $0.549 per pre-funded warrant, respectively. The pre-funded warrants will have an exercise price of $0.001 per share. In the second closing, upon achievement of the Milestone Event and if closing conditions are met, Talphera expects to issue additional shares of common stock and pre-funded warrants in the amount of $12 million, at a price of $0.55 per share and $0.549 per pre-funded warrant, respectively, with the allocation between common stock and prefunded warrants to be determined at that time.

In connection with the closing of this transaction, the Company has provided CorMedix with a 60-day period of exclusivity following the announcement of the achievement of the primary endpoint and topline clinical study results from the NEPHRO CRRT clinical study to negotiate a definitive agreement to acquire Talphera.
