PRGX Global, Inc. Announces First Quarter

2012 Financial Results

Operating Highlights

ATLANTA, April 30, 2012 — PRGX Global, Inc. (Nasdaq:PRGX), the world’s leading provider of recovery audit services and the pioneer in Profit Discovery™, today announced its unaudited financial results for the first quarter ended March 31, 2012.

“I am pleased to report year-over-year quarterly growth, particularly in light of our very strong performance in the first quarter last year,” said Romil Bahl, president and chief executive officer. “The PRGX team continues to demonstrate that our growth strategy remains on track.”

“Our growth strategy also continues to drive improved bottom line results. Our focus on reducing costs using our proprietary technology and global shared services model helped us deliver over $1 million more in Adjusted EBITDA this quarter compared to Q1 2011,” said Bahl.

“Each of our service segments is gathering steam. The Accounts Payable Recovery Audit core continues to increase its client count, take share in key geographies, and improve operating margins through our cost-to-serve reduction program. Our Healthcare Claims Recovery Audit business just delivered its best quarter since the launch of our growth strategy, validating our entrée into the large and rapidly expanding market for services targeting healthcare Fraud, Waste & Abuse. And finally, our Analytics & Advisory Profit Optimization services are recovering from the weakness encountered late last year and remain a tremendous growth opportunity for the Company over the coming three to five years,” concluded Bahl.

Consolidated Results for Three Months Ended March 31, 2012

Consolidated revenues for the first quarter of 2012 were $51.6 million compared to $50.7 million in the same prior year period. After adjusting for changes in foreign exchange rates, consolidated first quarter revenues in 2012 increased 2.9% compared to the same period in 2011.

Recovery Audit Services – Americas revenues for the first quarter of 2012 decreased 1.0% to $28.8 million compared to $29.1 million in the same period in the prior year. On a constant dollar basis, adjusted for changes in foreign exchange rates, Recovery Audit Services – Americas revenues decreased by 0.2% compared to 2011.

Recovery Audit Services – Europe Asia/Pacific revenues for the first quarter of 2012 decreased 3.0% to $14.3 million compared to $14.8 million in the same period in the prior year. On a constant dollar basis, adjusted for changes in foreign exchange rates, Recovery Audit Services – Europe Asia/Pacific revenues decreased by 1.4% compared to 2011.

New Services revenues for the first quarter of 2012 increased 25% to $8.5 million compared to $6.9 million in the same period in the prior year. The New Services segment represents Healthcare Claims Recovery Audit services and our Profit Optimization services.

Total cost of revenues for the first quarter of 2012 were $34.2 million, or 66.3% of revenue, compared to $34.6 million, or 68.2% of revenue, in the same period in the prior year. Cost of revenues as a percentage of revenue declined in all three of the Company’s reporting segments. SG&A for the first quarter of 2012 was $12.6 million compared to $12.4 million in the first quarter of 2011, 24.5% of revenue in each period. Depreciation and amortization expenses amounted to $3.8 million in the first quarter of 2012 compared to $2.3 million in the prior year first quarter. The increases in depreciation and amortization expenses are primarily attributable to the additional amortization charges resulting from the BSI acquisition in December 2011 and an associate migration in the UK completed in January 2012.

Net earnings for the first quarter of 2012 were $0.3 million, or $0.01 per basic and diluted share, compared to net earnings of $0.4 million, or $0.02 per basic and diluted share, for the same period in 2011. Net cash provided by operating activities for the first quarter of 2012 was $2.0 million compared to $6.2 million in the first quarter of 2011. The decrease in net cash provided by operating activities is due primarily to payments made in the first quarter of 2012 for incentive compensation, with no comparable amounts paid in the first quarter of 2011.

Adjusted EBITDA for the first quarter of 2012 was $6.8 million compared to $5.5 million of Adjusted EBITDA for the same period in 2011. The 2012 first quarter Adjusted EBITDA is earnings before interest, taxes, depreciation and amortization (EBITDA) excluding a charge of $1.4 million related to stock-based compensation, $0.2 million of transformation severance and related expenses, a $0.1 million charge for acquisition obligations classified as compensation, $0.2 million in legal fees relating to an overtime pay claim, and $0.3 million of foreign currency gains on intercompany balances. The comparable Adjusted EBITDA amount for the first quarter of 2011 excludes from EBITDA for such period a $0.9 million charge for stock-based compensation, $0.8 million of transformation severance and related expenses, a $0.1 million charge for acquisition obligations classified as compensation and $0.4 million of foreign currency gains on intercompany balances. Schedule 3 attached to this press release provides a reconciliation of net earnings to each of EBIT, EBITDA and Adjusted EBITDA.

Non-GAAP Financial Measures

EBIT, EBITDA and Adjusted EBITDA are all “non-GAAP financial measures” presented as supplemental measures of the Company’s performance. They are not presented in accordance with accounting principles generally accepted in the United States, or GAAP. The Company believes these measures provide additional meaningful information in evaluating its performance over time, and that the rating agencies and a number of lenders use EBITDA and similar measures for similar purposes. In addition, a measure similar to Adjusted EBITDA is used in the restrictive covenants contained in the Company’s secured credit facility. However, EBIT, EBITDA and Adjusted EBITDA have limitations as analytical tools, and you should not consider them in isolation, or as substitutes for analysis of the Company’s results as reported under GAAP. In addition, in evaluating EBIT, EBITDA and Adjusted EBITDA, you should be aware that, as described above, the adjustments may vary from period to period and in the future the Company will incur expenses such as those used in calculating these measures. The Company’s presentation of these measures should not be construed as an inference that future results will be unaffected by unusual or nonrecurring items. Schedule 3 to this press release provides a reconciliation of net earnings to each of EBIT, EBITDA and Adjusted EBITDA.
