STAMFORD, Conn., November 2, 2026 ― Information Services Group (ISG) (Nasdaq: III), a global AI-centered technology research and advisory firm, today announced financial results for the third quarter ended September 30, 2026.

“ISG delivered a robust financial performance in the third quarter, with strong cash generation, expanding margins and solid revenue growth,” said Michael P.

This mix of growth helped drive margin expansion to 15.4 percent, our highest quarterly margin in four years.

We are well-positioned to close out an outstanding 2026 and continue our momentum into the new year.”

Non-GAAP Financial Measures

ISG reports all financial information required in accordance with U.S. generally accepted accounting principles (GAAP). In this release, ISG has presented both GAAP financial results as well as non-GAAP information for the three and nine months ended September 30, 2026, and September 30, 2025. ISG believes that evaluating its ongoing operating results will be enhanced if it discloses certain non-GAAP information. These non-GAAP financial measures exclude non-cash and certain other special charges that many investors believe may obscure the user’s overall understanding of ISG’s current financial performance and ISG’s prospects for the future. ISG believes that these non-GAAP measures provide useful information to investors because they improve the comparability of the financial results between periods and provide for greater transparency of key measures used to evaluate the Company’s performance.

ISG provides adjusted EBITDA (defined as net income, plus interest, taxes, depreciation and amortization, foreign currency transaction gains/losses, non-cash stock compensation, interest accretion associated with contingent consideration, acquisition- and disposition-related costs, gains/losses on disposal of assets, gain on the sale of business, and severance, integration and other expense), adjusted net income (defined as net income, plus amortization of intangible assets, non-cash stock compensation, foreign currency transaction gains/losses, interest accretion associated with contingent consideration, acquisition- and disposition-related costs, gains/losses on disposal of assets, gain on the sale of business, and severance, integration and other expense on a tax-adjusted basis), and adjusted net income per diluted share, excluding the net tax effect of certain financial data, which are non-GAAP measures that ISG believes provide useful information to both management and investors by excluding certain expenses and financial implications of foreign currency translations, which management believes are not indicative of ISG’s core operations. These non-GAAP measures are used by ISG to evaluate the Company’s business strategies and management’s performance.

We evaluate our results of operations on both an as reported and a constant currency basis. The constant currency presentation, which is a non-GAAP financial measure, excludes the impact of year-over-year fluctuations in foreign currency exchange rates. We believe providing constant currency information provides valuable supplemental information regarding our results of operations, thereby facilitating period-to-period comparisons of our business performance and is consistent with how management evaluates the Company’s performance. We calculate constant currency percentages by converting our current and prior-periods local currency financial results using the same point in time exchange rates and then compare the adjusted current and prior period results. This calculation may differ from similarly titled measures used by others and, accordingly, the constant currency presentation is not meant to be a substitution for recorded amounts presented in conformity with GAAP, nor should such amounts be considered in isolation.

Management believes this information facilitates comparison of underlying results over time. Non-GAAP financial measures, when presented, are reconciled to the most closely applicable GAAP measure. Non-GAAP measures are provided as additional information and should not be considered in isolation or as a substitute for results prepared in accordance with GAAP. A reconciliation of the forward-looking non-GAAP estimates contained herein to the corresponding GAAP measures is not being provided, due to the unreasonable efforts required to prepare it.

Selected Financial Data

Constant Currency Comparison

1. Constant currency results are calculated by translating the underlying local currency amounts for all periods presented at the same foreign exchange rates. The foreign currency impact represents the difference between growth as reported and growth at constant exchange rates; a positive amount indicates currency translation increased reported results. Current period constant currency amounts equal reported results less the foreign currency impact. Prior period amounts are as reported.
