## Exhibit 99.1

**EXHIBIT 99.1**

**United-Guardian Reports 2025 Financial Results**

HAUPPAUGE, N.Y., March 27, 2026 (GLOBE NEWSWIRE) -- United-Guardian, Inc. (NASDAQ:UG) reported that net sales and net income for FY 2025 decreased compared to FY 2024. Net sales for the year decreased by 13% from $12,181,971 in 2024 to $10,545,468 in 2025, generating net income of $3,250,875 ($0.71 per share) in 2024 compared to $2,105,738 ($0.46 per share) in 2025.

Donna Vigilante, President of United-Guardian, stated, "Our financial performance in 2025 was primarily impacted by the decrease in sales of our cosmetic ingredients. One of the issues we faced was excess inventory held by our largest cosmetic ingredient distributor, Ashland Specialty Ingredients ("ASI"). The inventory overstock led to reduced order quantities from ASI throughout the year. The situation was further impacted by decreased global demand for our products, particularly in China, where heightened competition from local Asian producers, and the impact of global tariffs, negatively impacted sales. In response to these challenges, we have been collaborating closely with our distributor in China to regain lost market share, offering competitive pricing where feasible, differentiating our products from the competition, and exploring new markets where cost pressures are less pronounced."

"On a positive note, sales of pharmaceuticals and medical lubricants increased in 2025 compared to 2024, by 15% and by 4%, respectively. The increase in medical lubricants was driven by greater demand from two of our large contract manufacturer customers in China. The increase in pharmaceutical sales resulted from an increase in sales to all three of our national drug wholesalers, combined with a decrease in Medicare rebates. In 2025 we initiated a new marketing strategy to expand the domestic sales of Renacidin<sup>®</sup> by increasing awareness of Renacidin and seeking its inclusion on additional drug formularies. I am happy to report that we recently received approval from two major pharmacy benefit managers. We believe that having Renacidin available on additional drug formularies will enhance patient access and will support the product's long-term commercial growth. We are optimistic that this initiative, along with the new marketing and distribution agreements we entered into in 2025 for our cosmetic ingredients, will result in increased sales in the coming years."

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