standpoint, adjusted EBITDA was up 24 percent, with adjusted EBITDA margins expanding nearly 200 basis points. For the full year, revenue growth was led by the Americas, up 11 percent, excluding 2024 automation results, and our adjusted EBITDA was up 28 percent, while cash from operations rose 46 percent, to $29 million, all versus prior year."

Commenting on AI demand, Connors said, "Clients overall remain cautious in a still-uncertain macro environment but continue to invest in AI-related business transformation, cost optimization and insights to plan the journey ahead. In 2025, we served more than 350 clients with AI-focused research and advisory services, three times more than the prior year."

More broadly speaking, Connors said, "Clients are demanding business outcomes, a reshaping of their partner ecosystems and broader capability. This plays to our strengths. ISG is well positioned with our proprietary data, research, platforms and on-the-ground expertise to continue delivering great ROI for our clients."

AI Maturity Index Acquisition and AI Acceleration Strategy

In January 2026, ISG announced the acquisition of the AI Maturity Index, an AI readiness benchmarking and intelligence platform that allows clients to assess and track the AI readiness of their workforces on an individual and enterprise level and improve their employees' ability to leverage AI technology. The ISG AI Maturity platform is already generating strong interest, ISG said, with an early pipeline of more than 30 clients.

The move is part of ISG's broader AI acceleration strategy that includes the formation of an AI Acceleration Unit that brings an integrated, expert-led approach to helping clients rapidly scale AI.

ISG also is leveraging AI to improve the speed and efficiency of its proprietary client platforms, most notably ISG Tango™, the firm's groundbreaking sourcing platform. More than $25 billion of sourcing contract value now flows through ISG Tango™, up more than three times from 2024.
