The sources provide an overview of ADP's financial results and strategic progress during the first quarter of fiscal year 2026, primarily through excerpts from an earnings call, a supplemental presentation, and a press release. Revenue growth reached 7%, and adjusted diluted earnings per share also increased by 7%, with Employer Services (ES) new business bookings setting a first-quarter record. Despite a slight decline in ES retention and flat U.S. pays per control, the company reaffirmed its full-year fiscal 2026 consolidated outlook for revenue and adjusted EPS growth, citing better-than-expected client funds interest revenue as an offset. Management also highlighted advancements in Human Capital Management (HCM) technology, including the scaling of ADP Embedded Payroll, the acceleration of Workforce Now Next-Gen deployment, and the continued integration of AI initiatives across operations. Strategic moves included the acquisition of Pequity, a compensation management software provider, to bolster HCM offerings.
