[8-K] Jaguar Health, Inc. Reports Material Event

Rhea-AI Filing Summary

Jaguar Health, Inc. entered into new amendments to three existing royalty interest agreements, each with an original principal amount of $12 million. Beginning on April 1, 2026, the monthly royalty payment under each agreement must be the greater of $750,000 or the royalty amount otherwise owed for that month, increasing the company’s fixed payment obligation to its investors Iliad, Uptown, and Streeterville.

Jaguar and its subsidiary Napo Pharmaceuticals also amended a secured promissory note with an original principal amount of $6,220,812.50, extending its maturity date to April 1, 2026, which delays required repayment. In a separate exchange, Jaguar issued 361,271 shares of common stock in a private transaction to Streeterville in exchange for 25 shares of its Series M Preferred Stock, which were then cancelled, simplifying part of its capital structure.

Insights

Capital structure and credit analyst

Jaguar trades flexibility: higher future royalties for more time on debt.

Jaguar Health increases future cash commitments by setting each of its three royalty interests at a minimum monthly payment of $750,000 starting on April 1, 2026, or the higher amount otherwise due. This raises the predictability of payouts for Iliad, Uptown, and Streeterville but also raises Jaguar’s fixed obligations once the new terms take effect.

At the same time, extending the secured promissory note with an original principal of $6,220,812.50 to a new maturity on April 1, 2026 provides additional time before principal must be repaid, which can ease near-term liquidity pressure. The exchange of 361,271 common shares for 25 Series M Preferred shares reduces that preferred layer and modestly increases common equity, shifting value among security classes while keeping overall funding tied to existing investors.
