Ultra1Plus Ranks No. 2,446 on the 2025 Inc. 5000 - Fourth-Time Honoree on 173% Three-Year Growth.

CORAL GABLES, FL, Aug. 14, 2025. Ultra1Plus™, the consumer and industrial brand of Ultrachem LLC, today announced it ranks No. 2,446 on Inc. magazine’s 2025 Inc. 5000 list of America’s fastest-growing private companies. Powered by 173% revenue growth (2021–2024), this is Ultra1Plus’s fourth appearance on the list, proof of consistent execution, not a one-off spike.

Ultra1Plus™ blends and fills engine oils, transmission and hydraulic fluids, gear oils, coolants + antifreeze, and windshield washer fluids in the United States under ISO 9001:2015 and a current API Engine Oil Licensing & Certification System (EOLCS) License No. 3549, authorizing the API marks for multiple Ultra1Plus™ passenger-car and heavy-duty formulations (including SP/GF-6A & GF-6B and CK-4/CI-4 PLUS) through March 31, 2026.

Manufacturing and filling are kept in-house in Houston (outsourcing under 12%) for control, speed, and traceability end-to-end.

“We don’t sell stories, we ship auditable performance,” said Carmine Colarusso, CEO of Ultrachem LLC and U1Dynamics Manufacturing LLC. “API-licensed formulas, ISO discipline, and U.S. production you can verify. That’s how you earn repeat business and a fourth Inc. 5000 win.”

Ultra1Plus™ is expanding U.S. retail distribution, including Omni-Channels programs with Tractor Supply, Lowe’s, Home Depot, Northern Tool, Rural King, and ABC Auto parts, and scaling e-commerce across Amazon, Walmart, eBay, and Ultra1Plus.com, with additional reach in Mexico and Canada.

This year's Inc. 5000 honorees represent companies that have driven rapid revenue growth while navigating inflationary pressure, the rising costs of capital, and seemingly intractable hiring challenges. This year’s Inc. 5000 companies have added 874,458 jobs to the economy over the past three years.

Methodology

Companies on the 2025 Inc. 5000 are ranked according to percentage revenue growth from 2021 to 2024. To qualify, companies must have been founded and generating revenue by March 31, 2021. They must be U.S.-based, privately held, for-profit, and independent—not subsidiaries or divisions of other companies—as of December 31, 2024.
