UNITED GUARDIAN INC

United-Guardian, Inc. (NASDAQ: UG) operates through its Guardian Laboratories division as a specialty manufacturer of cosmetic, personal care, and sexual wellness ingredients alongside a portfolio of healthcare products including pharmaceuticals and medical lubricants. The company maintains its principal facility in Hauppauge, New York, a 50,000 square foot property encompassing manufacturing, warehouse, research and development, and office space.

The company's product portfolio spans four distinct categories. Cosmetic ingredients, representing 29 percent of sales, include the Lubrajel line of multifunctional hydrogel formulations designed for sensory enhancement, lubrication, hydration, and texture in personal care products. Medical lubricants account for 20 percent of revenue and serve applications in catheters, surgical instruments, and oral care products. Pharmaceutical products comprise 51 percent of sales, anchored by Renacidin, an FDA-approved prescription drug for preventing and dissolving calcifications in urethral catheters, and Clorpactin, a chlorine-based topical antimicrobial. The company also develops sexual wellness ingredients through its newly launched Natrajel line, though these products generated no sales during 2025.

United-Guardian distributes cosmetic ingredients globally through five distributors, with Ashland Specialty Ingredients serving as the largest partner. Pharmaceutical products reach market through three national full-line drug wholesalers, while medical lubricants are sold directly to manufacturers and contract manufacturers of finished medical products. The company entered into a distribution agreement with Brenntag Specialties in January 2026 to expand sexual wellness and Lubrajel product distribution across North America and France.

The company employs 25 people and maintains ISO 9001:2015 certification and EFfCI Good Manufacturing Practices certification for cosmetic ingredients. Approximately 77 percent of sales derive from domestic sources, with foreign sales concentrated in medical lubricants and cosmetic ingredients distributed through international partners. The company's website is www.u-g.com, with a dedicated pharmaceutical product site at www.renacidin.com. United-Guardian was founded in 1942 and has maintained continuous ISO compliance since 1998.
