ITEM 2.02. RESULTS OF OPERATIONS AND FINANCIAL CONDITION

​ On March 5, 2026 Information Services Group, Inc. (“ISG” or the “Company”) released its earnings for the fourth quarter 2025 which ended on December 31, 2025 and is furnishing a copy of the earnings release to the Securities and Exchange Commission under Item 2.02 of this Current Report on Form 8-K. In addition, ISG will discuss its financial results during a teleconference call on Friday, March 6, 2026 at 9:00am (ET). To access the teleconference call, go to ISG’s website at www.isg-one.com. The press release is furnished herewith as Exhibit 99.1 and shall not be deemed filed for purposes of the Exchange Act. ​ ISG reports all financial information required in accordance with U.S. generally accepted accounting principles (GAAP). ISG believes, however, that evaluating its ongoing operating results will be enhanced if it also 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 the Company’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, change in contingent consideration, acquisition and disposition-related cost, loss on the 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, change in contingent consideration, acquisition and disposition-related cost, loss on the disposal of assets, gain on the sale of business and severance, integration, and other expense on a tax-adjusted basis), adjusted net income per diluted share, adjusted EBITDA margin and selected financial data on a constant currency basis which are non-GAAP measures that the Company 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.

ITEM 2.02. RESULTS OF OPERATIONS AND FINANCIAL CONDITION

​ On August 5, 2024 Information Services Group, Inc. (“ISG” or the “Company”) released its earnings for the second  quarter 2024 which ended on June 30, 2024 and is furnishing a copy of the earnings release to the Securities and Exchange Commission under Item 2.02 of this Current Report on Form 8-K. In addition, ISG will discuss its financial results during a teleconference call on Tuesday, August 6, 2024 at 9:00am (ET). To access the teleconference call, go to ISG’s website at www.isg-one.com.  The press release is furnished herewith as Exhibit 99.1 and shall not be deemed filed for purposes of the Exchange Act. ​ ISG reports all financial information required in accordance with U.S. generally accepted accounting principles (GAAP).  ISG believes, however, that evaluating its ongoing operating results will be enhanced if it also 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 the Company’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-related costs, 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-related costs, severance, integration and other expense and write-off of deferred financing costs, on a tax-adjusted basis), adjusted net income per diluted share, adjusted EBITDA margin and selected financial data on a constant currency basis which are non-GAAP measures that the Company 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. ​ 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. ​

ITEM 2.02. RESULTS OF OPERATIONS AND FINANCIAL CONDITION

​ On March 9, 2023, Information Services Group, Inc. (“ISG” or the “Company”) released its earnings for the fourth quarter 2022 which ended on December 31, 2022 and is furnishing a copy of the earnings release to the Securities and Exchange Commission under Item 2.02 of this Current Report on Form 8-K. In addition, ISG will discuss its financial results during a teleconference call on Friday, March 10, 2023 at 9:00am (ET). To access the teleconference call, go to ISG’s website at www.isg-one.com. The press release is furnished herewith as Exhibit 99.1 and shall not be deemed filed for purposes of the Exchange Act. ​ ISG reports all financial information required in accordance with U.S. generally accepted accounting principles (GAAP). ISG believes, however, that evaluating its ongoing operating results will be enhanced if it also 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 the Company’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-related costs, 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-related costs, and severance, integration and other expense, on a tax-adjusted basis), adjusted net income per diluted share, adjusted EBITDA margin, gross-debt-to-adjusted-EBITDA ratio and selected financial data on a constant currency basis which are non-GAAP measures that the Company 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. ​ 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. ​

ITEM 2.02. RESULTS OF OPERATIONS AND FINANCIAL

CONDITION

On August 9, 2021, the Company released its earnings for the second quarter 2021 which ended on June 30, 2021 and is furnishing a copy of the earnings release to the Securities and Exchange Commission under Item 2.02 of this Current Report on Form 8-K. In addition, ISG will discuss its financial results during a teleconference call on Monday, August 9, 2021 at 9:00am (ET). To access the teleconference call, go to ISG’s website at www.isg-one.com. The press release is furnished herewith as Exhibit 99.1 and shall not be deemed filed for purposes of the Exchange Act.

ISG reports all financial information required in accordance with U.S. generally accepted accounting principles (GAAP). ISG believes, however, that evaluating its ongoing operating results will be enhanced if it also 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 the Company’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, change in contingent consideration, acquisition-related costs, severance, integration and other expense, and financing-related costs) and adjusted net income (defined as net income, plus amortization of intangible assets, non-cash stock compensation, foreign currency transaction gains/losses, change in contingent consideration, acquisition-related costs, severance, integration and other expense, financing-related costs, and write-off of deferred financing costs on a tax-adjusted basis) and selected financial data on a constant currency basis, which are non-GAAP measures that the Company believes provide useful information to both management and investors by excluding certain expenses and financial implications of foreign currency translations, that 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.

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.
