While adjusted EBITDA of $76 million declined 12% and declined 9% excluding divestitures, reflecting several one-time factors and mixed performance across our segments. Experiential Services delivered another very strong quarter, and both demand signals and execution continued to improve across this business, giving us confidence in second half growth. Retailer Services revenues increased 3% year-over-year, but adjusted EBITDA was down approximately 25% year-over-year, reflecting project timing and costs associated with early-stage project work that we do not anticipate repeating. In Branded Services, revenue declined 13% year-over-year and was down 11% excluding divestitures, as the recovery is taking longer than expected, and we are impacted by the same persistent challenges as our CPG clients.
Cash generation remains solid, with $19 million in adjusted unlevered free cash flow, despite an incremental working capital impact from our SAP final phase implementation. Turning to our growth initiatives, clients continue to prioritize programs that can demonstrate clear ROI, support trial and discovery, and convert demand into purchases. Demand for product demonstrations continues to exceed our expectations, with meaningful opportunities to expand event volume across existing customers and support growth with new customers. We are adding capacity where demand signals are strongest and remain confident in our ability to recruit and staff as needed.
We have seen strong growth across the spectrum of customers we serve, both in the U.S. We are focused on scalable, high-return opportunities that can become durable, long-term relationships as we deploy a highly trained and experienced team against what we see as recurring issues in out-of-stocks at retail. Together, these initiatives are designed to manage costs prudently, improve execution quality, and create capacity to support growth. Our centralized labor model continues to enhance labor planning and execution, which is critical as Experiential Services demand and Retailer Services project activity increase.
