Information Services Group Announces

Fourth-Quarter 2021 Results

STAMFORD, Conn., March 10, 2022 — Information Services Group (ISG) (Nasdaq: III), a leading global technology research and advisory firm, today announced record financial results for the fourth quarter and full year ended December 31, 2021.

“ISG delivered another outstanding financial performance in Q4, capping a historic 2021—our best year ever,” said Michael P. Connors, chairman and CEO. “Fourth-quarter revenues and adjusted EBITDA reached record highs, with adjusted EBITDA up 11 percent versus the prior year. Our strong performance is a direct result of our Go Digital strategy and ISG NEXT operating model, which are enabling us to capitalize on accelerating demand for all things digital. For the full year, revenues increased 12 percent, EBITDA margins increased more than 250 basis points, and our cash flow from operations was $42 million.”

Connors said ISG sees market momentum continuing in 2022. ”Enterprises are powering through the headwinds of the ongoing pandemic, inflation and supply chain disruptions in their drive to go digital. We see many companies still in the early stages of their digital and cloud journeys ramping up investments and looking for a trusted partner like ISG to determine a future vision, lead rapid change, find the right ecosystem partners and realize value at scale. We are well-positioned to build on our momentum in 2022.”

Fourth-Quarter 2021 Results

Reported revenues for the fourth quarter were a record $69.6 million, up 5 percent versus last year (up 6 percent in constant currency). Currency translation negatively impacted reported revenues by $0.7 million versus the prior year. Reported revenues were $38.9 million in the Americas, up 3 percent versus the prior year; $23.7 million in Europe, up 3 percent versus the prior year on a reported basis and up 6 percent in constant currency, and $7.0 million in Asia Pacific, up 27 percent versus the prior year on a reported basis and up 26 percent in constant currency.

ISG reported fourth-quarter operating income of $7.1 million, more than double its operating income of $3.5 million in the fourth quarter of 2020. The firm also more than doubled its fourth-quarter net income and earnings per share, reporting a record $3.6 million and $0.07, respectively, versus net income of $1.4 million and earnings per share of $0.03 in the prior year. Net income margin (calculated by dividing net income by reported revenues) more than doubled to 5 percent, from 2 percent in the prior year.

Statements contained herein including words such as “anticipate,” “believe,” “contemplate,” “plan,” “estimate,” “target,” “expect,” “intend,” “will,” “continue,” “should,” “may,” and other similar expressions, are “forward-looking statements” under the Private Securities Litigation Reform Act of 1995. These forward-looking statements are not guarantees of future results and are subject to certain risks and uncertainties that could cause actual results to differ materially from those anticipated. Those risks relate to inherent business, economic and competitive uncertainties and contingencies relating to the businesses of ISG and its subsidiaries including without limitation: (1) failure to secure new engagements or loss of important clients; (2) ability to hire and retain enough qualified employees to support operations; (3) ability to maintain or increase billing and utilization rates; (4) management of growth; (5) success of expansion internationally; (6) competition; (7) ability to move the product mix into higher margin businesses; (8) general political and social conditions such as war, political unrest and terrorism; (9) healthcare and benefit cost management; (10) ability to protect ISG and its subsidiaries’ intellectual property or data and the intellectual property or data of others; (11) currency fluctuations and exchange rate adjustments; (12) ability to successfully consummate or integrate strategic acquisitions; (13) outbreaks of diseases, including coronavirus, or similar public health threats or fear of such an event; and (14) engagements may be terminated, delayed or reduced in scope by clients. Certain of these and other applicable risks, cautionary statements and factors that could cause actual results to differ from ISG’s forward-looking statements are included in ISG’s filings with the U.S. Securities and Exchange Commission. ISG undertakes no obligation to update or revise any forward-looking statements to reflect subsequent events or circumstances.

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 months and twelve months ended December 31, 2021 and December 31, 2020. 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 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), 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), adjusted net income per diluted share 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.

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.
