CTG REPORTS FIRST QUARTER EPS INCREASE OF 20% TO $0.24

ON 5% REVENUE GROWTH

BUFFALO, N.Y. — April 22, 2013 — CTG (NASDAQ: CTGX), an information technology (IT) solutions and services company, announced its financial results for the 2013 first quarter which ended on March 29, 2013. Continued growth in higher margin solutions work primarily in its healthcare IT business, higher billable headcount, and expense control were the largest contributors to the strength of CTG’s 2013 first quarter results.

2013 First Quarter Review

Revenue, operating income, net income, and diluted net income per share for the 2013 first quarter as compared with the 2012 first quarter are as follows (dollar amounts in thousands except per share data):

The Company’s operating margin expanded by 30 basis points to 5.7% from 5.4% in the 2012 first quarter.

“CTG is reporting another excellent quarter, delivering results consistent with our expectations with revenue above the mid-point of guidance, even with this quarter having one less billing day than the 2012 first and fourth quarters” said CTG Chairman and Chief Executive Officer James R. Boldt. “Revenue in our staffing business was bolstered in the quarter by increased demand for technical resources as clients are becoming more confident in the sustainability of the domestic and global economic recovery. Our European operations continue to be in a growth mode with revenue up 13% in the quarter primarily based on increased business in our testing, healthcare, government and financial services practices. Healthcare revenue increased to 32% of total revenue from 31% a year ago though its growth was muted in the quarter as three large electronic medical records (EMR) projects awarded in February will not be staffed until the second quarter of 2013. Additionally, we started an ICD-10 remediation project in the first quarter and expect to begin two large legacy application management engagements in the second quarter.”

Mr. Boldt continued, “Notable events in the quarter included the board’s initiation in February 2013 of a quarterly cash dividend, which underscores our confidence in CTG’s current performance and long-term prospects. During the quarter, we also completed the acquisition of etrinity, a Belgium-based health IT services provider that markets to healthcare providers and specializes in clinical systems integration and implementation, application management, technology support for medical imaging, training, and technical resources. We are very optimistic about the long-term growth prospects for this business as healthcare organizations in several European countries are moving toward adoption of U.S. EMR software over the next few years. CTG is ideally positioned to capitalize on the Western Europe EMR opportunity as we bring our deep U.S. EMR selection and implementation experience and can leverage the significant technical resources of our European operations that have over 500 IT consultants based in the Benelux region and the United Kingdom.”

Solutions revenue in the 2013 first quarter increased by $1.9 million or 4.7% to $42.7 million, representing 39.4% of total revenue compared with 39.5% in the 2012 first quarter. Staffing revenue increased by $3.2 million or 5.1% to $65.8 million, or 60.6% of total revenue, compared with 60.5% in the 2012 first quarter. European revenue in the 2013 first quarter increased 13% to $19.4 million, or 17.9% of total revenue, from $17.2 million, or 16.6% of total revenue, in the 2012 first quarter. There were 63 billing days in the first quarter of 2013 and 64 billing days in the first and fourth quarters of 2012.

Selling, general, and administrative (SG&A) expenses were $16.4 million or 15.1% of revenue, compared with $16.3 million or 15.7% of revenue in the 2012 first quarter due to disciplined cost management and the effect of operating leverage resulting from revenue growth.

Cash used in operations was $7.1 million in the 2013 first quarter, compared with cash used in operations of $2.4 million in the 2012 first quarter. At March 29, 2013, the Company had $30.7 million in cash compared with $19.3 million at the end of the 2012 first quarter and $40.6 million at year-end 2012. Cash balances reflect both the 2013 and 2012 first quarters ending on a payroll date while the 2012 fourth quarter did not. The Company had no outstanding debt at the end of the 2013 or 2012 first quarters.

The Company’s effective tax rate in the 2013 first quarter was 33.2% compared with 39.4% in the 2012 first quarter. The lower tax rate in the quarter reflected the extension in January 2013, retroactive to 2012, of the federal R&D tax credit that expired in 2011.

The Company did not repurchase any of its shares in the 2013 first quarter. In April 2013, the Company extended its 10b5-1 stock repurchase plan to facilitate the repurchase of its common stock during its self-imposed blackout periods prior to the announcement of quarterly results. On March 29, 2013, approximately 535,000 shares were available under its current repurchase authorization.

2013 Second Quarter and Full Year Guidance

CTG is providing guidance for the 2013 second quarter and 2013 full year in the table below. Based on its current business activity and trends in its business, the Company is reiterating revenue and earnings guidance from the initial guidance provided in its 2012 fourth earnings release issued on February 19, 2013.

Mr. Boldt commented, “We are confirming our revenue guidance for the year based upon first quarter demand for staffing and our current expectations for our healthcare business. Growth in our healthcare business is expected from several sources this year including the EMR projects already underway, the three recently awarded EMR projects, and prospective new EMR wins. We are currently working on 15 significant EMR projects; we will begin three new projects in the second quarter which we announced in February 2013; and we are awaiting decisions on three requests for proposals received from clients for new EMR projects. We also expect growth from ICD-10 remediation engagements, our new genomics offering, consulting work related to health reform mandates, and the expansion of our application management practice. We are very encouraged by our sales efforts for our software as a service offerings, especially our fraud, waste and abuse (FWA) offering. We recently sold our FWA offering to a second health insurance client and, based upon where we are in the sales cycle with other prospective clients, are forecasting that we will sell our FWA offering to additional clients this year. We look for the continued growth in solutions work from these higher margin offerings to move operating margins above the six percent mark in 2013. Overall, we expect 2013 will be an excellent year and the seventh year of the last eight of significant double-digit earnings growth.”
