INFORMATION SERVICES GROUP ANNOUNCES

SECOND QUARTER AND FIRST HALF 2010 FINANCIAL RESULTS

Company reports second quarter revenues of $33.4 million,

adjusted EBITDA of $4.2 million and adjusted EPS of $0.06

A 6% rise in revenues versus prior year period was best since the recession began on double-

digit growth rates in the Americas and Asia Pacific, offset by declines in Europe

TPI launches new Cloud Computing Solutions Unit

STAMFORD, Conn., August 2, 2010 — Information Services Group, Inc. (ISG) (NASDAQ: III), an industry-leading, information-based services company, today announced financial results for the second quarter of 2010.

Second Quarter 2010 Results and Operating Highlights

ISG reported total revenues of $33.4 million, an increase of $1.9 million, or 6%, from $31.5 million in the second quarter of 2009. Revenues before client reimbursable expenses (fee revenue) totaled $30.9 million, an increase of 5% (also 5% in constant currency terms).

Adjusted earnings before interest, taxes, depreciation, amortization and non-cash stock compensation and impairment charges (adjusted EBITDA, a non-GAAP measure) totaled $4.2 million, or 13.7% of fee revenue, compared with $4.4 million, or 14.9% of fee revenue, in the second quarter 2009. Excluding the impact of currency translation, adjusted EBITDA declined $0.7 million or 13% from second quarter 2009 levels.

Operating income of $1.0 million compared with $1.4 million of operating income for the second quarter of 2009. The decline in operating income and adjusted EBITDA was due to increased client-related industry events which were not held last year due to the recession and the greater use of contract labor, which was partially offset by the 2009 restructuring accrual and the reversal of variable compensation accruals.

Reported fully diluted earnings per share (EPS) of $0.01 compared with $0.00 for the second quarter of 2009; fully diluted adjusted EPS of $0.06 was flat with second quarter EPS in the prior year.

“We have completed the second quarter with revenue growth of 6% versus the prior year period, our highest growth rate since the recession began, fueled by strong performance in the Americas with 10% growth and Asia Pacific up 38% year on year on a constant currency basis. During the quarter, we advised on a $2 billion deal between GM and HP; signed a major drug chain to a Governance Services contract; and added several new blue-chip clients. These deals helped to offset weakness in Europe, as revenue declined 8% (in constant currency) in the second quarter as companies deferred some sourcing decisions amid the uncertain economic and financial climate,” said Michael P. Connors, Chairman and CEO of ISG.

Mr. Connors added, “While I am pleased with our second quarter results, recent economic volatility may continue to drive existing and potential clients to postpone major sourcing decisions, extending sales cycles relative to historical levels. Yet the challenges facing our clients persist regardless of the economic environment in which they operate. As their trusted advisor we continue to bring resources and insight into our clients’ most pressing needs, which is why I am thrilled to announce the launch of our latest initiative: The Cloud Computing Solutions Unit.”

The new TPI Cloud Computing Business Solutions Unit, led by industry veteran Kevin Smilie, is uniquely positioned to provide companies with objective guidance on best practices for the identification, acquisition, transition and management of private and public Cloud solutions. According to TPI Research, nearly four out of five clients indicated that they have had internal discussions about Cloud Computing.

TPI in mid-May hosted 150 client executives for its 2010 TPI Americas Sourcing Leadership Exchange (SLE), which is the firm’s annual client event (cancelled last year due to the recession). At the forum, held this year in Boston, MA, TPI announced new research highlighting its value proposition: helping clients to save an estimated $50 billion through the use of sourcing strategies.

Capital and Liquidity

Cash and cash equivalents totaled $40.4 million at June 30, 2010, a net increase of $2.6 million from March 31, 2010. Total outstanding debt at June 30, 2010 was $69.8 million, the same as at March 31, 2010.

First Half 2010 Results

ISG reported revenue of $68.2 million during the first half of 2010, an increase of $2.4 million or 4% compared with $65.8 million in the first half of 2009. Excluding the impact of currency translation on reported results, first half 2010 revenue increased $0.6 million or 1%.

Revenue in the Americas increased by 6% and Asia Pacific by 17%, in constant currency terms. Growth was attributable to increases in information technology, business process and post contract governance services. These increases were partially offset by a decline in revenue in Europe of 12% on a constant currency basis. Fee revenues aggregated $63.1 million during the first half of 2010, an increase of 3% year-over-year including the impact of currency translation (essentially flat compared to prior year before the impact of currency translation).

Operating income for the first six months of 2010 was $2.7 million, a $0.7 million or 22% decrease from a first half 2009 total of $3.4 million. Operating income decreased 40% before the impact of currency translation. ISG’s first half 2010 adjusted EBITDA totaled $9.0 million (14.3% of fee revenues), a decrease of 5% (14% before currency impacts) or $0.5 million from first half 2009 adjusted EBITDA of $9.5 million (15.5% of fee revenues). Decreases in both operating income and adjusted EBITDA for the first half of 2010 resulted primarily from higher expenses for industry related client events and the greater use of contract labor that was partially offset by the 2009 restructuring accrual.

Reported fully diluted EPS for the first half of 2010 totaled $0.02, which was flat compared to 2009. Fully diluted adjusted EPS for the first half of 2010 was $0.13, flat with 2009.

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 six months ended June 30, 2010 and 2009. 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 income taxes, net interest income/(expense), depreciation, amortization of intangible assets resulting from acquisitions, non-cash stock compensation and non-cash impairment charges for goodwill and intangible assets) and adjusted net income (defined as net income plus amortization of intangible assets, non-cash stock compensation and non-cash impairment charges for goodwill and intangible assets on a tax adjusted basis) and selected financial data on a constant currency basis (using foreign currency exchange rates as of November 30, 2009), 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. Certain prior period amounts have been reclassified to conform to the current period presentation and definitions of non-GAAP measurements. 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.
