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

EXCLUDING A ONE-TIME GAIN OF 5 CENTS PER SHARE;

BOARD OF DIRECTORS INITIATES QUARTERLY CASH DIVIDEND OF 5 CENTS PER SHARE

BUFFALO, N.Y. — February 19, 2013 — CTG (NASDAQ: CTGX), an information technology (IT) solutions and services company, announced its financial results for the 2012 fourth quarter and full year which ended on December 31, 2012. The increase in higher margin solutions work from the ramp-up of new healthcare projects and expansion of larger healthcare engagements, the operating leverage from revenue growth, and increased billable headcount were the primary contributors to the strength of 2012 fourth quarter and full year financial results.

Diluted net income per share for the 2012 fourth quarter included proceeds of $0.8 million, included in other income, from life insurance benefits paid to the Company upon the death in the quarter of a former CTG senior executive. Excluding this non-recurring gain, net income per diluted share for the 2012 fourth quarter was $0.24, 20% higher than the 2011 fourth quarter.

The initial quarterly cash dividend of $0.05 declared by CTG’s Board of Directors at its February meeting is payable on April 1, 2013 to shareholders of record on March 22, 2013.

2012 Fourth Quarter Review

Revenue, operating income, net income, and diluted net income per share for the 2012 fourth quarter as compared with the 2011 fourth quarter are as follows (dollar amounts in thousands except per share data):

The Company’s operating margin expanded by 50 basis points to 5.9% from 5.4% in the 2011 fourth quarter.

“CTG closed out another excellent year with a very strong fourth quarter highlighted by earnings per share, excluding the one-time gain, at the top of guidance and up 20%, an operating margin of 5.9%, and further growth of our healthcare business to one-third of total revenue,” said CTG Chairman and Chief Executive Officer James R. Boldt. “For the quarter, we again delivered significant growth in earnings and margins, along with a continued shift in our business mix to more profitable solutions work which was 42% of revenue. As expected, client concerns about domestic and global economic uncertainty are muting growth in our less profitable staffing business which was up 3.4% in the quarter and 0.7% in 2012. The 18% increase in healthcare IT revenue to 33% of 2012 revenue was the primary driver of the increases in solutions work and CTG’s revenue and earnings last year.”

Mr. Boldt continued, “Reflecting CTG’s strong balance sheet and our optimism in the company’s growth prospects, the Board decided to initiate a quarterly cash dividend. CTG joins the ranks of other high performing technology companies that are able to further enhance shareholder value by paying a

2

dividend. Based on CTG’s record of earnings growth over several years, significant cash flows, and favorable future outlook, we are confident in our ability to fund further investments in our business, continued share repurchases, and a regular dividend.”

Solutions revenue in the 2012 fourth quarter increased by $5.0 million or 12.3% to $45.3 million, representing 42% of total revenue compared with 40% in the 2011 fourth quarter. Staffing revenue increased by $2.0 million or 3.4% to $62.6 million, or 58% of total revenue, compared with 60% in the 2011 fourth quarter. European revenue was $18.3 million, or 17.0% of total revenue, in the 2012 fourth quarter, a $1.8 million increase from $16.5 million, or 16.4% of total revenue, in the 2011 fourth quarter. Foreign currency exchange fluctuations had a $0.7 million unfavorable effect on revenue in the quarter compared with the 2011 fourth quarter. There were 64 billing days in the fourth quarter of 2012 and 63 billing days in the fourth quarter of 2011.

Selling, general, and administrative (SG&A) expenses were $17.1 million or 15.8% of revenue, compared with $17.3 million or 17.2% of revenue in the 2011 fourth quarter.

Cash provided from operations was $11.4 million in the 2012 fourth quarter, compared with cash provided from operations of $10.2 million in the 2011 fourth quarter. At December 31, 2012, the Company had $40.6 million in cash compared with $22.4 million at the end of the 2011 fourth quarter. The Company had no outstanding debt at the end of the 2012 or 2011 fourth quarters.

2012 Full Year Review

Results for the 2012 full year reflect the same trends seen in the fourth quarter. Revenue, operating income, net income, and diluted net income per share for 2012 as compared with 2011 were as follows (dollar amounts in thousands except per share data):

The Company’s operating margin in 2012 expanded by 90 basis points to 5.8% from 4.9% in 2011. In 2012, CTG’s solutions business increased 17.9% to $173.6 million, or 41% of total revenue, and its staffing business grew 0.7% to $250.8 million, or 59% of total revenue. European revenue increased 2.4% in 2012 to $68.6 million and represented 16.2% of total revenue. Foreign currency exchange fluctuations had a $5.4 million unfavorable effect on revenue in 2012 compared with 2011. At December 31, 2012, headcount was 3,900, an increase of 200, or 5%, from 3,700 at year-end 2011.

Selling, general, and administrative expenses were $66.9 million, or 15.8% of revenue, compared with $65.0 million, or 16.4% of revenue, in 2011. In 2012, CTG recorded $2.9 million in depreciation and $1.9 million for capital expenditures.

The Company’s effective tax rate in 2012 was 36.5% compared with 37.6% in 2011. The lower tax rate in 2012 reflected the effect of the non-taxable life insurance proceeds received in 2012.

Stock Repurchase Program

CTG repurchased 25,000 of its shares in the 2012 fourth quarter at an average price of $17.55 per share. In 2012, the Company repurchased 326,000 shares at an average price of $14.03 per share. In January 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 December 31, 2012, approximately 535,000 shares were available under its current repurchase authorizations.

2013 Guidance

CTG is issuing the following initial guidance for 2013 based on its current business activity and forecast:

Mr. Boldt commented, “We have excellent momentum going into 2013 and look for growth this year to primarily come from our very profitable healthcare IT business. We expect 2013 first quarter revenue and earnings to be comparable to the 2012 fourth quarter despite the first quarter having one less billing day. Implementation of electronic medical records (EMR) systems will continue to be a major

4

contributor to healthcare revenue as we are currently working on 17 large EMR projects and also have 2 proposals, previously bid on, that are awaiting client decisions. We also expect growth in multiple areas including EMR optimization projects for healthcare providers, short- and long-term application management outsourcing engagements, other system implementations, and consulting work in both the provider and payer markets. Work from the engagement that began last year for our medical treatment evaluation tool will continue through most of 2013.

Over the last decade, the expansion of CTG’s healthcare IT business has come entirely from internal growth that has established us as one of the largest U.S. healthcare IT providers. With our recent acquisition of etrinity, a Belgium-based provider of healthcare IT services, we are particularly optimistic about our prospects in Western Europe as several countries there are moving toward adopting U.S. EMR systems and some of the major healthcare software companies have recently set up European operations. Based on CTG’s significant EMR experience, the etrinity acquisition, and the fact that we are already a large provider of IT services in the Benelux region, we are very well positioned to capitalize on the emerging European EMR opportunity.”

Mr. Boldt concluded, “We remain very excited about CTG’s growth prospects as we further our transformation to an IT service and solutions company with a focus on healthcare IT. The strength of our healthcare IT business and industry demand, combined with our acquisition of etrinity and our recently announced genomics offering, puts us on course for growth in 2013 and beyond.”
