Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On April 2, 2026, Kyntra Bio, Inc. (“Kyntra Bio” or the “Company”) received a letter from the Nasdaq Listing Qualifications Staff of the Nasdaq Stock Market notifying us that the Company no longer complies with the Nasdaq Global Select Market continued listing requirement of $50 million in total assets and total revenue for the most recently completed fiscal year (or two of the last three most recently completed fiscal years) per Listing Rule 5450(b)(3)(A). This is due to the revenue of FibroGen International being presented as held for sale (in discontinued operations) in 2024 and 2025. The Company does not currently meet the alternative requirements of Listing Rule 5450(b) (either the shareholders’ equity or the market value of listed securities standards).

The notification received has no immediate effect on the listing of Kyntra Bio’s common stock on Nasdaq. Under the Nasdaq Rules, the Company has 45 days (May 18, 2026) to submit a plan to regain compliance and if such plan is accepted, Nasdaq may grant the Company with an extension of up to 180 days (September 29, 2026) to evidence compliance.

Per Listing Rule 5810(c)(2)(D), the Company may submit a plan that demonstrates current or near term compliance with the listing requirements relating to stockholders’ equity or market value of listed securities. In determining whether to accept our plan, Nasdaq will consider such things as the likelihood that the plan will result in compliance with Nasdaq’s continued listing criteria, the Company’s past compliance history, the reasons for the Company’s current non-compliance, other corporate events that may occur within the review period, the Company’s overall financial condition, and its public disclosures.

Kyntra Bio may also consider applying to transfer the Company’s securities to the Nasdaq Capital Market.
