1. Business

United-Guardian, Inc. (“Company”) is a Delaware corporation that, through its Guardian Laboratories division, manufactures, markets and develops specialty cosmetic ingredients, notably a line of Lubrajel^® hydrogels, pharmaceutical products, medical lubricants and sexual wellness ingredients. In October 2023, the Company entered into a distribution agreement with Brenntag Specialties, a global market leader in chemicals and ingredients distribution, for the distribution of the Company’s new Natrajel^® line of sexual wellness ingredients in the United States, Canada, Mexico, Central America and South America. Although there were no sales of these products during 2024, the Company anticipates that it will begin manufacturing and reporting sales of this new line of products in the second half of 2025.

The Company conducts various Research and Development (“R&D”) activities. Our R&D department primarily develops new and unique specialty cosmetic and sexual wellness ingredients. We also develop new medical lubricants for our medical customers. The Company develops new products using natural and environmentally friendly raw materials, which is a priority for many of our cosmetic customers. Our R&D department also modifies, refines, and expands the uses for existing products, with the goal of further developing the markets that our products are used in. All the products that we market, except for Renacidin^®, are produced at our facility in Hauppauge, New York. Renacidin, a urological irrigation solution, is manufactured for us by an outside contract manufacturer.
