Management Comments

“CRA’s fourth quarter performance was driven by companywide utilization of 80% and solid contributions from across our portfolio,” said Paul Maleh, CRA’s President and Chief Executive Officer. “We’re pleased that both Litigation/Regulatory and Management Consulting continued to build upon the positive momentum we achieved during the third quarter of fiscal 2013.”

“On a year-over-year, non-GAAP basis, our portfolio delivered 12.6% revenue growth in the fourth quarter. Six practice areas, in particular, delivered even stronger year-over-year revenue growth: Antitrust & Competition Economics, Auctions & Competitive Bidding, Financial Economics, Intellectual Property, Life Sciences, and Transfer Pricing.”

“Selling, general and administrative operations also performed well and helped to improve our efficiency gains during the fourth quarter. On a non-GAAP basis, fourth quarter SG&A expenses, after adjusting for commissions to non-employee experts, decreased to 18.6% from 19.3% a year ago. For fiscal 2013, non-GAAP SG&A expenses, after adjusting for commissions to non-employee experts, decreased to 19.0%, compared with 21.1% in fiscal 2012.”

“As a result of our improved operating performance and collection efforts, cash and cash equivalents increased to $51.3 million as of December 28, 2013, up from $17.9 million at the end of the third quarter of fiscal 2013.”

Outlook

“On the heels of a strong second half of fiscal 2013, we are encouraged by our prospects for increasing profitability and revenue growth in fiscal 2014, both organically and through strategic hires. We are pleased with the level of lead flow activity and the quality of the conversion rate into revenue generating projects. While we remain cautious about our clients’ spending patterns, the broad-based demand for our services and the solid foundation we have put in place give us optimism that the momentum experienced during the past six months will continue into fiscal 2014,” Maleh concluded.

Share Repurchase Expansion

CRA also announced today that its Board of Directors has authorized an expanded share repurchase program of up to $15.0 million of CRA’s common stock, in addition to the $1.4 million remaining under its existing share repurchase program.

CRA will finance the existing and expanded repurchase programs with available cash. CRA may repurchase shares in open market purchases or in privately negotiated transactions in accordance with applicable insider trading and other securities laws and regulations. The timing and extent to which CRA repurchases shares under these programs will depend upon market conditions and other corporate considerations as may be considered in its sole discretion.

“CRA has the financial resources available to fund the existing and expanded share repurchase program while continuing to execute its corporate strategy,” said Wayne Mackie, CRA’s Chief Financial Officer.

CRA also announced today that its Board of Directors has authorized management to enter into a Rule 10b5-1 plan on behalf of CRA. CRA expects that the plan, once effective, will be in place through the end of 2014. The plan will allow CRA to repurchase its shares at times when it otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods. A broker selected by CRA will have the authority under the terms and limitations specified in the plan to repurchase shares on the Company’s behalf in accordance with the terms of the plan. Because the repurchases under the plan are subject to certain pricing parameters, there is no guarantee as to the exact number of shares that will be repurchased under the plan, or that there will be any repurchases pursuant to the plan.

Non-GAAP Financial Measures

In addition to reporting its financial results in accordance with U.S. generally accepted accounting principles, or GAAP, the Company has also provided in this release non-GAAP financial information.  The Company believes the use of non-GAAP measures in addition to GAAP measures is an additional useful method of evaluating its results of operations.  The Company believes that presenting its financial results excluding certain restructuring costs, certain non-cash expenses, and the results of the Company’s NeuCo subsidiary is important to investors and management because it is more indicative of the Company’s ongoing operating results and financial condition.  These non-GAAP financial measures should be considered in conjunction with, but not as a substitute for, the financial information presented in accordance with GAAP, and the expected results calculated in accordance with GAAP and reconciliations to those expected results should be carefully evaluated.  The non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.

Specifically, for the fourth quarter and full-year of fiscal 2013, the Company has excluded NeuCo’s results. For the fourth quarter and full year of fiscal 2012, the Company has excluded certain restructuring costs, a non-cash goodwill impairment charge, and NeuCo’s results. In calculating “Adjusted EBITDA” on a GAAP and non-GAAP basis, the Company has excluded the following non-cash expenses:  depreciation and amortization, share-based compensation expenses, and amortization of forgivable loans. The calculation of Adjusted EBITDA on a non-GAAP basis for

the periods presented includes all of the adjustments generally applicable to that period as described above in this paragraph.
