## Exhibit 99.1

**EXHIBIT 99.1**

**XORTX Meets Nasdaq Continued Listing Requirements**

CALGARY, Alberta, April 21, 2026 (GLOBE NEWSWIRE) -- XORTX Therapeutics Inc. ("**XORTX**" or the "**Company**") (NASDAQ: XRTX \| TSXV: XRTX \| Frankfurt: ANU), a late-stage clinical pharmaceutical company focused on developing innovative therapies to treat gout and progressive kidney disease, is pleased to announce that it has received a letter of compliance from the Nasdaq Stock Market LLC's ("**Nasdaq**") Listing Qualifications Department in connection with Nasdaq Rule 5550(a)(2) that requires a listed company's shares to maintain a minimum bid price of US$1.00 per share (the "**Minimum Bid Requirement**"). In order to regain compliance, the Company's common shares were required to trade at or above US$1.00 per share for at least 10 consecutive trading days. Following implementation of a 1 for 5 reverse split of the Company's common shares on April 6, 2026, this requirement was met on April 17, 2026, and the Company received the compliance letter from Nasdaq April 20, 2026. As a result, the deficiency in the Minimum Bid Requirement has been cured.

**About XORTX Therapeutics Inc.**

In addition, the Company is developing XRx-225, a pre-clinical stage program for Type 2 diabetic nephropathy and recently acquired VB4-P5 program, which is currently at the pre-IND stage of development and targets both rare and prevalent forms of kidney disease. XORTX is working to advance products that target aberrant purine metabolism and xanthine oxidase to decrease or inhibit production of uric acid. At XORTX, we are dedicated to developing medications that improve the quality of life and health of individuals with gout and other important diseases.
