SAN FRANCISCO, CA / ACCESS Newswire / May 20, 2026 / Jaguar Health, Inc. (NASDAQ:JAGX) ("Jaguar" or the "Company") today reported its consolidated first-quarter 2026 financial results.

2026 FIRST QUARTER COMPANY FINANCIAL RESULTS:

• Neonorm^™: Revenues for the non-prescription Neonorm products were minimal for the first quarters of 2026 and 2025.

• Non-GAAP Recurring EBITDA: Non-GAAP recurring EBITDA for the first quarters of 2026 and 2025 were a net loss of $6.4 million and $9.7 million, respectively.

Note Regarding Use of Non-GAAP Measures

The Company supplements its condensed consolidated financial statements presented on a GAAP basis by providing non-GAAP EBITDA and non-GAAP recurring EBITDA, which are considered non-GAAP under applicable SEC rules. Jaguar believes that the disclosure items of these non-GAAP measures provide investors with additional information that reflects the basis upon which Company management assesses and operates the business. These non-GAAP financial measures are not in accordance with GAAP and should not be viewed in isolation or as substitutes for GAAP net sales and GAAP net loss and are not substitutes for, or superior to, measures of financial performance in conformity with GAAP.

The Company defines non-GAAP EBITDA as net loss before interest expense and other expense, depreciation of property and equipment, amortization of intangible assets, share-based compensation expense and provision for or benefit from income taxes. The Company defines non-GAAP Recurring EBITDA as non-GAAP EBITDA adjusted for certain non-recurring revenues and expenses. Company management believes that non-GAAP EBITDA and non-GAAP Recurring EBITDA are meaningful indicators of Jaguar's performance and provide useful information to investors regarding the Company's results of operations and financial condition.
