[5][6][7][8] The merger was officially completed on April 1, 2020,[9][10] and in August, the company's name was announced as Ultimate Kronos Group (UKG), which became effective on October 1.

[12] In December 2021, UKG launched its Close the Gap Initiative, a $3 million campaign funded by the company to address salary inequity for U.S. workers' wages, in particular for women and people of color.

In 2023, the company sponsored a $1 million prize for the NWSL Challenge Cup, an annual tournament organized by the National Women's Soccer League.

According to Society for Human Resource Management, the new company became one of the largest HR technology vendors in the highly competitive economy section that includes ADP, Ceridian, Taleo, Successfactors, and Workday.

The acquisition allowed UKG to incorporate EverythingBenefits’ procedural knowledge including its suite of payroll, HR service delivery, and workforce management, among other tools.

[28][29] Established in 2007, Workforce Institute is the company's think tank and research platform for organizations providing information on Human Capital Management issues that include working environment optimization, analytical and educational tools, accommodation of people with disabilities and more.

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.

[37][38][39][40][41] Many sources reported that the attack possibly occurred as a result of the Log4Shell zero-day, but UKG claimed it did not have evidence of Log4Shell being responsible for the ransomware incident.
