## Summary

Ultimate-Kronos merger HCM with $3.5B+ revenue; UKG Pro payroll and UKG Dimensions workforce scheduling competing with ADP and Workday for enterprise HR and complex labor scheduling in healthcare and retail.

## Company Overview

UKG (Ultimate Kronos Group) is a Weston, Florida-based human capital management (HCM) and workforce management company formed from the 2020 merger of Ultimate Software and Kronos — providing payroll, HR, talent management, time and attendance, scheduling, and workforce analytics to organizations ranging from mid-market to large enterprise. With $3.5+ billion in annual revenue and 15,000+ employees, UKG is one of the largest HCM vendors globally, competing with ADP and Workday for enterprise workforce management.

UKG's dual platform architecture reflects its merger origin: UKG Pro (formerly Ultimate Software's UltiPro) provides the HR and payroll core for mid-to-large employers, while UKG Ready (formerly Kronos Workforce Ready) serves the mid-market with a more integrated suite. The UKG Dimensions (formerly Workforce Dimensions) platform targets large enterprise workforce scheduling and time management — particularly relevant for complex shift scheduling in healthcare, manufacturing, and retail where optimizing labor allocation against demand forecasts is a daily operational challenge. The combined company's 80,000+ customer base provides scale in both product development and support.

In 2025, UKG competes in the HCM and workforce management market with ADP (NASDAQ: ADP, the market leader by revenue), Workday (NASDAQ: WDAY, the enterprise HCM leader), Ceridian (NASDAQ: CDAY, Dayforce HCM), and Paycom/Paylocity for human capital management platform market share. UKG's workforce management (scheduling, time and attendance) heritage from Kronos is its strongest differentiator — Kronos built decades of labor scheduling expertise for healthcare (nurse scheduling), retail, and manufacturing that pure HR platforms lack. The UKG-Ceridian competitive battle (both targeting the same mid-market enterprise segment) has intensified. The 2025 strategy focuses on UKG Pro Workforce Management AI (AI-powered scheduling optimization), growing the Great Place to Work integration (UKG acquired GPTW in 2021), and migrating legacy Kronos on-premise customers to UKG cloud.
