EXHIBIT 99.1

United-Guardian Reports First Quarter Results

HAUPPAUGE, N.Y., May 08, 2026 (GLOBE NEWSWIRE) -- United-Guardian, Inc. (NASDAQ:UG) announced today the financial results for the first quarter of 2026. First quarter sales increased from $2,481,127 in 2025 to $2,872,222 in 2026, with net income increasing from $560,895 ($0.12 per share) to $818,902 ($0.18 per share).

Donna Vigilante, President of United-Guardian, stated, “I am happy to report that sales and earnings increased in the first quarter of 2026 compared with the first quarter of 2025. Our financial performance was primarily driven by increased sales of both our pharmaceuticals and cosmetic ingredients. Pharmaceutical sales rose by 24% in the first quarter of 2026, driven primarily by increased demand for Renacidin®, our most important pharmaceutical product. Sales of our cosmetic ingredients increased by 21%, with the increase primarily attributable to an increase in purchases by our largest cosmetic ingredient distributor, Ashland Specialty Ingredients (“ASI”). ASI’s purchases increased by 45% in the first quarter of 2026 compared with the first quarter of 2025. The lower purchases by ASI in 2025 were primarily the result of ASI carrying excess inventory, which suppressed its purchase levels. This excess inventory has now been worked off, and they have resumed regular purchase levels.”

“In addition to the increase in sales, our income for the quarter was also supplemented by settlement income we recognized from the contract manufacturer (“CM”) of Renacidin in connection with an unexpected shutdown at the CM’s facility in late 2023, which resulted in lost Renacidin sales.”

“With ASI resuming its regular purchasing pattern, new distribution agreements in place, increased emphasis on expanding our “natural” product lines, and our ongoing project to increase outreach and market penetration for Renacidin, we are optimistic that our sales will continue to increase in 2026.”

United-Guardian is a manufacturer of cosmetic ingredients, pharmaceuticals, medical lubricants, and sexual wellness ingredients.
