UKG (Ultimate Kronos Group) is an American multinational technology company with dual headquarters in Lowell, Massachusetts, and Weston, Florida. UKG is the AI-first Workplace Operating Platform with unified HR, payroll, and workforce management services.
History On February 20, 2020, Ultimate Software and Kronos Incorporated announced an agreement to form a new cloud computing venture, specializing in workforce management and human capital management. The combined company, valued at $22 billion, would be one of the largest cloud computing companies in the world. The merger was officially completed on April 1, 2020, and, in August, the company's name was announced as Ultimate Kronos Group (UKG), which became effective on October 1.
In December 2021, UKG disclosed that it was targeted by a ransomware attack that was first detected on December 11, 2021. The malware attack affected the Kronos Private Cloud feature used by many large businesses including Boots, Gap Inc., Marriott International, MGM Resorts International, PepsiCo, Sainsbury's, Samsung, Staples Inc., Tesla, Inc., Whole Foods Market, Yamaha Corporation, YMCA, and others while some governmental entities such as the cities of Cleveland, Springfield, Massachusetts as well as the New York Metropolitan Transportation Authority were also affected. Many sources reported that the attack possibly occurred as a result of the Log4Shell zero-day, but UKG claimed it had no evidence that Log4Shell was responsible for the ransomware incident.
In July 2024, Jennifer Morgan became chief executive officer.
