Press Release

PRGX Global, Inc. Announces First Quarter

2016 Financial Results

ATLANTA, April 28, 2016 — PRGX Global, Inc. (Nasdaq:PRGX), a global leader in Recovery Audit and Spend Analytics services, today announced its unaudited financial results for the first quarter ended March 31, 2016.

“We started 2016 with solid first quarter Recovery Audit revenue performance as we continue to ramp up our new clients and increase our value proposition to existing clients. For the first time in over three years, we achieved top line growth in our Recovery Audit services on a constant dollar basis and after adjusting for a significant client bankruptcy which occurred in the second half of 2015. Including these adjustments, first quarter revenue from continuing operations was essentially flat compared to the same period in 2015,” said Ron Stewart, president and chief executive officer.

“In addition, we continue to gain traction in our Adjacent Services businesses as our Supplier Information Management services posted another quarterly increase in year over year revenue. In our Spend Analytics offerings, we commenced work on multiple new projects during the quarter, although contracting delays and billing approvals delayed recognition of certain revenue, which we expect to recognize over the next few quarters,” continued Stewart.

“While I’m encouraged with our continued progress in executing our transformation strategy, we still have a lot of work ahead of us in order to accomplish our long-term objectives,” concluded Stewart.

Consolidated Results from Continuing Operations for the Three Months Ended March 31, 2016

Consolidated revenue from continuing operations for the first quarter of 2016 was $31.2 million, compared to $33.0 million for the same period last year. On a constant dollar basis adjusted for changes in foreign exchange rates, revenue decreased by 2.8% in 2016, compared to the same period in 2015. On a constant dollar basis excluding the revenue from a large client who filed bankruptcy in 2015, revenue from the Americas Recovery Audit segment was essentially flat in the first quarter of 2016 when compared to the same period in 2015. On a constant dollar basis, the Europe/Asia-Pacific Recovery Audit segment grew 3.2% for the first quarter of 2016 when compared to the same period in 2015. On a constant dollar basis, the Adjacent Services segment revenue declined $0.7 million for the first quarter of 2016, compared to the same period in 2015. The 2015 amount includes approximately $0.4 million from a document service business which was sold in the third quarter of 2015.

Total cost of revenue from continuing operations for the first quarter of 2016 was $21.6 million, or 69.3% of revenue, compared to $23.2 million, or 70.2% of revenue, in the same period last year, for a 1.3% improvement as a percentage of revenue. The improvement was primarily related to the Company’s continued operational process improvements, partially offset by the costs associated with new regional senior operations leaders that were not in place in the first quarter of 2015.

SG&A expenses from continuing operations for the first quarter of 2016 were $8.8 million, compared to $7.9 million in the prior year period. This increase was primarily driven by the costs associated with new sales personnel who were not in place in the first quarter of 2015 and an increase in U.S. healthcare benefit costs. These increases were partially offset by reductions in other general and administrative costs.

Consolidated net loss-earnings from continuing operations for the first quarter of 2016 was essentially breakeven including the loss-earnings per basic and diluted share, compared to a net loss of $(2.3) million, or loss per basic and diluted share of $(0.09), for the same period of 2015.

Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (Adjusted EBITDA) from continuing operations for the first quarter of 2016 was $2.0 million, or 6.5% of revenue, compared to Adjusted EBITDA of $3.2 million, or 9.6% of revenue, in the first quarter 2015. 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.

Cash Flow and Liquidity

Net cash provided by operating activities for the first quarter of 2016 was $4.9 million, compared to $5.4 million in the first quarter of the prior year. At March 31, 2016, the Company had unrestricted cash and cash equivalents of $15.7 million, no borrowings against its $20.0 million revolving credit facility, and no bank debt outstanding.

Stock Repurchase Program

Since the February 2014 announcement of the Company’s stock repurchase program, as of March 31, 2016, the Company has repurchased 8.4 million shares, or 27.9% of its common stock outstanding on the date of the announcement. As previously announced in October 2015, the Company’s Board of Directors approved a $10 million increase (to $50 million) in the program and extended the duration of the program to December 31, 2016. The Company repurchased 0.7 million shares of its outstanding common stock for an aggregate cost of $2.6 million in the quarter ended March 31, 2016. As of April 22, 2015, the Company had approximately 21.9 million shares of common stock outstanding.

Extension of Employment Agreement of Chief Executive Officer

The Company also announced today the extension of Ron Stewart’s employment agreement, providing for his continued service as the Company’s Chief Executive Officer through December 31, 2018. Details of the amendment to Mr. Stewart’s employment agreement will be included in a Form 8-K to be filed with the Securities and Exchange Commission.

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.
