SAN FRANCISCO, CA / ACCESS Newswire / September 15, 2026 / Jaguar Health, Inc. (NASDAQ:JAGX) ("Jaguar" or the "Company") today announced that the Company will effect a reverse stock split of its issued and outstanding voting common stock ("Common Stock"), at an exchange ratio of 1-for-15, on Thursday, September 17, 2026 (the "Effective Date") in order to support the Company's compliance with Nasdaq's listing standards.

The new CUSIP number for the Company's Common Stock following the reverse stock split is 47010C854.

The effectuation of the reverse stock split follows the approval of a proposal submitted to Jaguar stockholders at the Company's April 2026 Special Meeting of Stockholders (the "Special Meeting").

The proxy statement is also available on the Company's corporate website.

When the reverse stock split becomes effective, every fifteen (15) shares of the Company's Common Stock immediately prior to the Effective Date shall automatically be reclassified into one (1) share of Common Stock, without any change in the par value per share, and this change will be reflected on Nasdaq's website and other stock quote platforms. No fractional shares will be issued as a result of the reverse stock split. Stockholders who otherwise would be entitled to receive a fractional share in connection with the reverse stock split will receive a cash payment in lieu thereof.
