PRGX Global, Inc. Announces Second Quarter

2014 Financial Results

ATLANTA, July 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 second quarter ended June 30, 2014.

“The PRGX Global team bounced back during the quarter to deliver solid results, increasing revenue nearly 11% over the first quarter,” said Ron Stewart, president and chief executive officer. “Compared to Q1, our core recovery audit business increased revenue by 14% and increased Adjusted EBITDA by 49%. Leading the way was our Europe/Asia-Pacific team, recording strong sequential and year-over-year revenue and Adjusted EBITDA growth.”

“Outside of our core business, our Adjacent Services business delivered improved Adjusted EBITDA compared to Q1 on comparable revenue. And finally, our Healthcare Claims Recovery Audit segment continues to be challenged as we wind down our obligations related to the Medicare RAC subcontracts,” continued Mr. Stewart.

“We are starting to see elements of our strategy take effect. This includes continuing to drive process standardization in our core business and moving more work to our global shared service centers, thereby improving efficiencies and reducing costs. The expansion of our audit capabilities into targeted industries and geographies is also bearing fruit, especially in the Oil & Gas industry, where we’ve built a significant backlog of work. In addition, key projects started near the end of the quarter have us excited about the promise of Adjacent Services and we remain focused on our goal of achieving profitability in this portion of our business by year end,” concluded Mr. Stewart.

Consolidated Results for the Three Months Ended June 30, 2014

Consolidated revenue for the second quarter of 2014 decreased 16.4% to $42.0 million compared to $50.2 million in the same prior year period. After adjusting for changes in foreign exchange rates, consolidated second quarter revenue in 2014 decreased 17.2% compared to the same period in 2013.

Recovery Audit Services – Americas revenue for the second quarter of 2014 decreased 8.0% to $27.0 million compared to $29.4 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 for the second quarter of 2014 decreased by 7.2% compared to the same period in 2013. Most of this reduction is the result of the rate and scope reductions at several large clients, as previously communicated. Further, while there has been a significant increase in contract compliance claims production, conversion of these claims to revenue has been delayed.

Recovery Audit Services – Europe/Asia-Pacific revenue for the second quarter of 2014 increased 15.0% to $12.4 million compared to $10.8 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 revenue for the second quarter of 2014 increased by 9.1% compared to the same period in 2013. The majority of this increase is due to audit growth in key clients in Australia and improved claim conversion within Europe.

Adjacent Services revenue for the second quarter of 2014 was $2.3 million compared to $3.1 million in the same period in the prior year. The majority of this decrease was expected as the Company continues to rationalize and refine its offerings in this segment.

Healthcare Claims Recovery Audit Services revenue for the second quarter of 2014 was $0.3 million compared to $6.9 million in the same period in the prior year. This expected decrease in revenue was primarily attributable to the substantial reduction in auditing as part of the Medicare RAC program.

Total cost of revenue for the second quarter of 2014 was $29.9 million, or 71.3% of revenue, compared to $32.5 million, or 64.8% of revenue, in the same period last year. Nearly half of this margin erosion was due to the wind down of the Medicare RAC program, with the remainder due to the decline in revenue in the other segments as well as our investment in our Contract Compliance services. SG&A for the second quarter of 2014 was $11.0 million compared to $11.6 million in the same period last year, a decrease of $0.6 million. Excluding transformation severance and related expenses, the year over year decrease in SG&A expenses for the quarter was $1.5 million. Depreciation and amortization expenses were $2.5 million in the second quarter of 2014 compared to $3.4 million in the prior year second quarter.

Net loss for the second quarter of 2014 was $(1.5) million, or $(0.05) per basic and diluted share, compared to net income of $1.8 million, or $0.06 per basic and diluted share, for the same period in 2013. Net cash provided by operating activities for the second quarter of 2014 was $2.9 million compared to net cash used in operating activities of $4.0 million in the second quarter of 2013.

Adjusted EBITDA for the second quarter of 2014 was $3.8 million compared to $8.0 million of Adjusted EBITDA for the same period in 2013, a decline of $4.2 million, of which $3.5 million is attributable to Healthcare Claims Recovery Audit Services. Second quarter 2014 Adjusted EBITDA is earnings before interest, taxes, depreciation and amortization (EBITDA) excluding a charge of $1.0 million related to stock-based compensation, $1.6 million of transformation severance and related expenses, a $0.2 million charge for acquisition-related charges, and $0.2 million of foreign currency gains on short-term intercompany balances. The comparable Adjusted EBITDA amount for the second quarter of 2013 excludes from EBITDA for such period a $1.2 million charge related to stock-based compensation, $0.6 million of transformation severance and related expenses, a $0.2 million charge for acquisition-related charges, and $0.2 million of foreign currency losses on short-term intercompany balances. Schedule 3 attached to this press release provides a reconciliation of net income (loss) to each of EBIT (earnings before interest and taxes), 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 income (loss) to each of EBIT, EBITDA and Adjusted EBITDA.
