On May 27, 2026, Jaguar Health, Inc. (the “Company”) issued a press release announcing the Decision Letter (as defined below) from the Nasdaq Hearings Panel, a copy of which is furnished as Exhibit 99.1.

The information in Exhibit 99.1 attached hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section, or incorporated by reference into any of the Company’s filings under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in any such filing.

As previously disclosed, on April 24, 2026, the Company received formal notice that the Nasdaq Hearings Panel (“Panel”) had granted the Company’s request for continued listing on The Nasdaq Stock Market LLC (“Nasdaq”), subject to the condition that the Company demonstrate compliance with Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Rule”) by May 15, 2026. On May 6, 2026, the Company received a superseding decision from the Panel granting the Company’s request for an extension to demonstrate compliance with the Bid Price Rule, from May 15, 2026, to May 18, 2026.

On May 26, 2026, the Company was formally notified by Nasdaq that the Company had regained compliance with the Bid Price Rule (the “Compliance Determination”) but that the Panel would maintain jurisdiction over the Company and its listing until September 1, 2026, the outside date of the Panel’s discretion in this matter.

The Compliance Determination further stated that, in accordance with Listing Rule 5815(d)(4)(B), the Company is subject to a Mandatory Panel Monitor for a period of one year from the date of the Compliance Determination, or May 26, 2027. If within the one-year monitoring period Nasdaq determines that the Company has failed to evidence a closing bid price of at least $1.00 per share for 30 consecutive business days, the Company will not be afforded a 180-day grace period otherwise automatically available under Listing Rule 5810(c)(3). Rather, Nasdaq would issue a delist determination, at which time the Company may request a new hearing before the Panel. The Company’s request for a hearing would stay any further action by Nasdaq at least pending the hearing and the expiration of any extension period that may be granted by the Panel following such hearing.

This Current Report on Form 8-K contains “forward-looking” statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. The words “may,” “will,” “could,” “would,” “should,” “expect,” “intend,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “project,” “potential,” “continue,” “ongoing” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. While the Company believes its plans, intentions and expectations reflected in those forward-looking statements are reasonable, these plans, intentions or expectations may not be achieved.

For information about the factors that could cause such differences, please refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, including the information discussed under the captions “Item 1 Business,” “Item 1A. Risk Factors” and “Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations,” as well as the Company’s various other filings with the SEC. Given these uncertainties, you should not place undue reliance on these forward-looking statements. The Company assumes no obligation to update any forward-looking statement.
