PRGX Global, Inc. Announces Fourth Quarter

and Full Year 2012 Financial Results

Operating Highlights

ATLANTA, February 25, 2013 — 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 fourth quarter and year ended December 31, 2012.

“I am pleased to report our third consecutive year of revenue growth following the launch of our growth strategy in late 2009. The global PRGX team demonstrated year-over-year and sequential revenue growth for each quarter in 2012, but even more impressive was our 28.3% growth in Adjusted EBITDA over 2011, on top of 13% growth in 2011 over 2010. Clearly, PRGX is delivering on the promise of Profit Discovery,” said Romil Bahl, president and chief executive officer.

Continued Bahl, “In our core recovery audit business, we continue to reap the benefits of our focus on client services and our service delivery model improvements. The positive results of our Americas business reflect the investments we have made in our core business over the past few years. Despite serving some of our more competitive and mature markets, our Americas team achieved 100% client retention and grew annual revenue by 5% over 2011. In addition, the Americas team lowered total cost of revenue from 2011 while delivering almost $6 million in incremental revenue growth. The fact that our gross margin improvements accelerated in the second half over the first half of 2012 bodes well for the future.”

“Our Recovery Audit Services – Europe/Asia-Pacific (EAP) team showed stabilization in the fourth quarter with a rebound in revenue and Adjusted EBITDA compared to earlier in the year. While there are continuing economic challenges throughout the region, we believe that as we deploy our global delivery model and invest in our client relationships across the region, our results will improve,” said Bahl.

“Our New Services segment finished the year strong, delivering 51% year-over-year revenue growth for the quarter and 29% annual growth. Our Healthcare Claims Recovery Audit business grew revenue over 2011 while consistently delivering on the Medicare RAC program and winning two additional Medicaid RAC contracts. Our Profit Optimization business also finished 2012 on a positive trajectory, overcoming the weakness experienced at the start of the year. And finally, as was committed to when we initiated our investment phase in the segment, New Services delivered positive Adjusted EBITDA in 2012,” concluded Bahl.

Consolidated Results for Three Months Ended December 31, 2012

Consolidated revenue for the fourth quarter of 2012 was $53.1 million compared to $49.9 million in the same prior year period. After adjusting for changes in foreign exchange rates, consolidated fourth quarter revenue in 2012 increased 6.1% compared to the same period in 2011.

Recovery Audit Services – Americas revenue for the fourth quarter of 2012 increased 7.9% to $30.0 million compared to $27.8 million in the same period in the prior year. On a constant dollar basis, adjusted for changes in foreign exchange rates, Recovery Audit Services – Americas revenue increased by 8.0% compared to 2011.

Recovery Audit Services – Europe Asia/Pacific revenue for the fourth quarter of 2012 decreased 11.4% to $14.7 million compared to $16.5 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 revenue decreased by 12.2% compared to 2011.

New Services revenue for the fourth quarter of 2012 increased 51.4% to $8.5 million compared to $5.6 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 revenue for the fourth quarter of 2012 was $34.4 million compared to $34.2 million in the fourth quarter of 2011. This result included decreases in both of our recovery audit segments driven by the expanded use of our Next-Generation Recovery Audit service model, offset by an increase in our New Services segment, which primarily was due to higher costs in both our Healthcare Claims Recovery Audit business and our Profit Optimization services incurred to support the increased revenue in these areas. SG&A for the fourth quarter of 2012 was $14.0 million compared to $12.0 million in the fourth quarter of 2011. The increase in SG&A in the fourth quarter of 2012 compared to the 2011 fourth quarter was primarily due to increased equity compensation charges, information systems costs, provisions for bad debts, and wage claim costs.

Net earnings for the fourth quarter of 2012 were $1.5 million, or $0.06 per basic and diluted share, compared to net earnings of $1.3 million, or $0.05 per basic and diluted share, for the same period in 2011. The fourth quarter 2012 net earnings include a net tax benefit of $0.3 million compared to a net tax benefit of $1.2 million in the fourth quarter of 2011. The 2012 net tax benefit primarily resulted from the release of a portion of the reserves held for uncertain tax positions, while the 2011 net tax benefit primarily resulted from a reduction of the Company’s valuation allowance on deferred tax assets. The 2012 release of a portion of the reserves held for uncertain tax positions also included a reversal of related interest accruals, resulting in negative interest expense

of $0.6 million in the fourth quarter of 2012 compared to net interest expense of $0.4 million in the fourth quarter of 2011. Net cash provided by operating activities for the fourth quarter of 2012 was $6.5 million compared to $6.6 million in the fourth quarter of 2011.

Adjusted EBITDA for the fourth quarter of 2012 was $8.2 million compared to $6.4 million for the same period in 2011. The 2012 fourth quarter Adjusted EBITDA is earnings before interest, taxes, depreciation and amortization (EBITDA) excluding a charge of $1.8 million related to stock-based compensation, $1.1 million of transformation severance and related expenses, a $0.1 million charge for acquisition obligations classified as compensation, $0.4 million of wage claim costs and $0.2 million of foreign currency gains on intercompany balances. The comparable Adjusted EBITDA amount for the fourth quarter of 2011 excludes from EBITDA for such period a $1.4 million charge for stock-based compensation, $0.8 million of transformation severance and related expenses, a $0.5 million charge for acquisition transaction costs and acquisition obligations classified as compensation, and $0.2 million of foreign currency losses on intercompany balances. Schedule 3 attached to this press release provides a reconciliation of net earnings to each of EBIT (earnings before interest and taxes), EBITDA and Adjusted EBITDA.

Consolidated Results for the Year Ended December 31, 2012

Consolidated revenue for the year ended December 31, 2012 increased 2.7% to $208.5 million, compared to $203.1 million in the prior year. After adjusting for changes in foreign exchange rates, 2012 revenue increased 4.2% compared to 2011.

Recovery Audit Services – Europe Asia/Pacific revenue for the year ended December 31, 2012 decreased 12.6% to $53.8 million compared to $61.6 million in the prior year. On a constant dollar basis, adjusted for changes in foreign exchange rates, Recovery Audit Services – Europe Asia/Pacific revenue decreased by 10.0% compared to 2011.

New Services revenue for the year ended December 31, 2012 increased 28.5% to $33.1 million compared to $25.7 million in the prior year. Revenue from New Services represented 15.9% of consolidated revenue in the year ended December 31, 2012 compared to 12.7% of consolidated revenue in 2011.

Cost of revenue as a percentage of revenue in the Recovery Audit Services – Americas segment improved from 56.1% in 2011 to 52.8% in 2012 and in the Recovery Audit Services – Europe/Asia-Pacific segment deteriorated slightly from 76.5% in 2011 to 77.6% in 2012 due primarily to higher transformation severance costs and lower revenue in 2012. The New Services segment posted a gross margin of $4.6 million in 2012 compared to $0.3 million in 2011, resulting primarily from the ramp up of revenue.

SG&A for the year ended December 31, 2012 was $52.5 million compared to $49.1 million in 2011. The increase in SG&A in 2012 compared to 2011 was primarily due to business development investments, costs of strategic hires to support New Services, increased incentive compensation accruals, wage claim costs, and increased severance and other costs related to the Company’s service delivery model transformation.

Net earnings for the year ended December 31, 2012 were $5.4 million, or $0.21 per basic and diluted share, compared to net earnings of $2.8 million, or $0.11 per basic and diluted share, for 2011. Net cash provided by operating activities for the year ended December 31, 2012 was $18.8 million compared to $19.3 million in 2011.

Adjusted EBITDA for the year ended December 31, 2012 was $31.4 million compared to $24.5 million in 2011. For the year ended December 31, 2012, Adjusted EBITDA was earnings before interest, taxes, depreciation and amortization (EBITDA) excluding a charge of $6.3 million related to stock-based compensation, $2.1 million of charges incurred as part of the Company’s service delivery model transformation, a $0.4 million charge for acquisition obligations classified as compensation, $1.0 million of wage claim costs, and $0.4 million of foreign currency gains on intercompany balances. The comparable Adjusted EBITDA amount for the year ended December 31, 2011 excludes from EBITDA for such period a $5.1 million charge for stock-based compensation, $2.0 million of charges incurred as part of the Company’s service delivery model transformation, a $0.8 million charge for acquisition transaction costs and acquisition obligations classified as compensation, and $0.4 million of foreign currency losses 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.
