FLORHAM PARK, N.J., Nov. 01, 2022 (GLOBE NEWSWIRE) — Phathom Pharmaceuticals, Inc. (Nasdaq: PHAT), a biopharmaceutical company focused on developing and commercializing novel treatments for gastrointestinal diseases and disorders, today announced that up to an additional $40 million in non-dilutive capital has been secured from an additional investor under the terms of Phathom’s revenue interest financing agreement announced on May 4, 2022.

Up to $40 million has been committed, comprised of $15 million upon FDA approval of vonoprazan for treatment of EE, and $25 million upon achievement of a sales milestone. This additional potential funding is subject to the revenue interest financing agreement with Sagard Healthcare Partners, NovaQuest Capital Management, and Hercules Capital, Inc. (NYSE: HTGC) which provided Phathom with the option to add additional investors for up to $40 million in additional funding. This additional $40 million in potential funding increases the total financing available to Phathom under the agreement to up to $300 million.

In exchange for the commitment to provide these cash payments, the investors will receive a 10% royalty on Phathom’s net sales of products containing vonoprazan. The royalty payment will be reduced to 1% on incremental net sales that exceed certain annual thresholds following regulatory approval of vonoprazan for symptomatic non-erosive reflux disease (NERD). The total royalties payable by Phathom to the investors are capped at 2.0x of the total payments received from the investors. Upon achievement of the cap amount, the agreement will terminate.

Morgan Stanley & Co. LLC acted as sole structuring agent on the transaction.
