PRGX Global, Inc. Announces First Quarter

2014 Financial Results

ATLANTA, April 28, 2014 — PRGX Global, Inc. (Nasdaq:PRGX), the world’s leading provider of accounts payable recovery audit services and the pioneer in Profit Discovery™, today announced its unaudited financial results for the first quarter ended March 31, 2014.

Consolidated revenue for the first quarter of 2014 was $37.9 million compared to $45.1 million in the same prior year period, a decrease of 16.0%. After adjusting for changes in foreign exchange rates, consolidated revenue for the first quarter of 2014 decreased 15.3% compared to the same period in 2013. Beginning with the first quarter of 2014, the former New Services segment is now being reported as two segments: Adjacent Services, which were formerly referred to as Profit Optimization services, and Healthcare Claims Recovery Audit services.

Recovery Audit Services – Americas revenue for the first quarter of 2014 was $24.8 million compared to $26.2 million in the same period in the prior year, a decrease of 5.5%. On a constant dollar basis, adjusted for changes in foreign exchange rates, Recovery Audit Services – Americas revenue decreased 3.3% compared to 2013. The decrease in revenue was primarily attributable to the delay of several large claims and a delayed audit start in a large legacy client.

Recovery Audit Services – Europe/Asia-Pacific revenue for the first quarter of 2014 was $9.7 million compared to $11.0 million in the same period in the prior year, a decrease of 11.9%. On a constant dollar basis, adjusted for changes in foreign exchange rates, Recovery Audit Services – Europe/Asia-Pacific revenue decreased 14.6% compared to 2013. Similar to the Americas, the revenue decline was primarily attributable to claim delays at a significant client.

Adjacent Services revenue for the first quarter of 2014 was $2.3 million compared to $3.9 million in the same period in the prior year, a decrease of 42.1%. The decrease in revenue was due to a weak backlog coming into 2014 compared to 2013.

Healthcare Claims Recovery Audit Services revenue for the first quarter of 2014 was $1.1 million compared to $3.9 million in the same period in the prior year, a decrease of 71.3%. Healthcare Claims Recovery Audit Services consist primarily of services provided under subcontracts related to the Medicare RAC program. The decrease in revenue was primarily attributable to the reduced scope of the current Medicare RAC program.

Adjusted EBITDA for the first quarter of 2014 was $0.5 million compared to $3.6 million of Adjusted EBITDA for the same period in 2013, a decline of $3.1 million. The reduction in Adjusted EBITDA included a decline in Healthcare Claims Recovery Audit Services Adjusted EBITDA of $1.3 million and a decline in Adjacent Services Adjusted EBITDA of $1.2 million. Schedule 3 attached to this press release provides a reconciliation of net loss to each of EBIT (earnings before interest and taxes), EBITDA and Adjusted EBITDA.

Net loss for the first quarter of 2014 was $(3.7) million, or $(0.12) per basic and diluted share, compared to a net loss of $(0.5) million, or $(0.02) per basic and diluted share, for the same period in 2013. Net cash provided by operating activities for the first quarter of 2014 was $2.9 million compared to $0.8 million in the first quarter of 2013.

“While our first quarter results were disappointing, they were not unexpected. These results reflect the anticipated declines in the Healthcare Claims Recovery Audit and Adjacent Services segments. On a positive note, our core recovery audit business remains solid, although Q1 results were negatively impacted by several timing delays which we expect to be fully resolved by the end of 2014,” said Ron Stewart, president and chief executive officer. “Additionally, I am pleased we were able to reduce our operating expenses by over $4.0 million in the quarter compared to last year.”

“We are now fully engaged with the implementation of our revised strategy. Our “Blue Chip” client list and attractive value proposition, coupled with the most talented team in the industry and an unmatched global footprint, affirms my confidence in PRGX. I am confident we have built a solid business platform from which to achieve sustainable profitability,” concluded Mr. Stewart.

At March 31, 2014, the Company had unrestricted cash and cash equivalents of $45.7 million, no borrowings against its revolving credit facility, and no bank debt outstanding.

Such statements include both implied and express statements regarding the Company’s overall condition and growth prospects, anticipated plans and financial results for the remainder of 2014, the strength of the Company’s core recovery audit business, the Company’s decision to withdraw from the Medicare RAC rebid process, the long term business objectives for the Company, including its Healthcare Claims Recovery Audit business and its Adjacent Services business. Such forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties and other factors that may cause the actual results, performance or achievements of the Company to differ materially from the historical results or from any results expressed or implied by such forward-looking statements. Risks that could affect the Company’s future performance include revenue that does not meet expectations or justify costs incurred, the Company’s ability to develop material sources of new revenue in addition to revenue from its core recovery audit services, changes in the market for the Company’s services, the Company’s ability to retain and attract qualified personnel, changes to Medicare and Medicaid recovery audit contractor programs and the effects of the Company’s decision to withdraw from the Medicare RAC rebid process, the Company’s ability to integrate recent and future acquisitions, uncertainty in the credit markets, the Company’s ability to maintain compliance with its financial covenants, client bankruptcies, loss of major clients, and other risks generally applicable to the Company’s business.

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 loss to each of EBIT, EBITDA and Adjusted EBITDA.
