CTG REPORTS 2013 THIRD QUARTER EPS OF $0.23

New One Million Share Repurchase Authorization Announced

BUFFALO, N.Y. — October 21, 2013 — CTG (NASDAQ: CTG), an information technology (IT) solutions and services company, announced its financial results for the 2013 third quarter which ended on September 27, 2013. CTG also announced today that its Board of Directors approved a new one million common share repurchase authorization.

“The highlight of third quarter results is an operating margin of 6.0% for the second consecutive quarter, the highest level in almost 15 years,” said CTG Chairman and Chief Executive Officer James R. Boldt. “The strength of our margin is coming from disciplined expense control, which enabled us to generate earnings that met guidance despite lower than expected revenue.”

“Our healthcare business declined from last year as a number of hospital clients are holding off on system investments while they determine how to adjust their cost structure to deal with lower reimbursements as a result of the U.S. federal budget sequestration. While the federal budget sequestration is affecting

revenue growth from healthcare providers in the short term, we also know that hospitals must invest in EMR systems to comply with health reform mandates and to lower costs in order to remain competitive and financially viable in a rapidly changing business environment. More recently we have seen a significant increase in requests for proposals for healthcare application outsourcings, which provide a way for hospitals to reduce their operating costs without making significant financial investments. Late in the quarter, we secured our first European EMR advisory consulting project, an important first step toward doing more significant full-scale EMR implementations as European healthcare providers begin to adopt U.S. EMR software packages to improve healthcare delivery and lower costs.”

“Further working to our benefit in the future growth of our healthcare IT business is a strong reputation and standing in the marketplace as reflected by CTG Health Solutions recently placing seventh in the Modern Healthcare 2013 annual ranking of the largest healthcare management consulting firms, three spots above the 2012 survey. CTG Health Solutions was also named as a 2013 Modern Healthcare Best Place to Work in Healthcare which enhances our ability to recruit experienced health IT consultants in a highly competitive market for health IT talent.”

2013 Third Quarter Review

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

The Company’s operating margin improved by 10 basis points to 6.0% from 5.9% in the 2012 third quarter.

Solutions revenue in the 2013 third quarter was $40.0 million, representing 40% of total revenue compared with 42% of total revenue in the 2012 third quarter. Staffing revenue was $60.7 million, or 60% of total revenue, compared with 58% of total revenue in the 2012 third quarter. European revenue increased 12% to $18.2 million, or 18% of total revenue, from $16.3 million, or 15% of total revenue, in the 2012 third quarter. Foreign currency exchange fluctuations had a $1.0 million favorable effect on revenue in the quarter compared with the 2012 third quarter. The increase in revenue from CTG’s European operations is attributable to growth in its financial services practice and the addition of etrinity, the Belgium-based health IT services provider acquired in February 2013. There were 63 billing days in the third quarter of 2013 and 2012.

Selling, general, and administrative (SG&A) expenses in the 2013 third quarter were $15.1 million, or 15% of revenue, a 10% decrease from $16.8 million, or 15.8% of revenue, in the 2012 third quarter.

Cash provided by operations was $3.0 million in the 2013 third quarter compared with cash provided by operations of $6.2 million in the 2012 third quarter. At September 27, 2013, the Company had $31.5 million in cash compared with $29.4 million at the end of the 2012 third quarter. The Company had no outstanding debt at the end of the 2013 and 2012 third quarters. The tax rate for the quarter was 35.2%.

2013 Year-to-date Review

Results for the first three quarters of the year reflect the same trends seen in the third quarter. Revenue, operating income, net income, and diluted net income per share for the first three quarters of 2013 as compared with the first three quarters of 2012 are as follows (dollar amounts in thousands except per share data):

The Company’s operating margin increased by 20 basis points to 5.9% in the first three quarters of 2013 from 5.7% in the same period of 2012. For the first three quarters of 2013, CTG’s solutions business was $124.3 million, or 39% of total revenue, and its staffing business was $192.0 million, or 61% of total revenue. European revenue in the first three quarters of 2013 increased 12% to $56.2 million, or 18% of total revenue, compared with $50.3 million or 16% of total revenue in the comparable 2012 period.

Selling, general, and administrative expenses were $47.8 million, or 15.1% of revenue, a decrease of $2.0 million or 4% from $49.8 million, or 15.7% of revenue, in the first three quarters of 2012.

Stock Repurchase Program

CTG repurchased 225,000 of its shares in the 2013 third quarter at an average price of $18.41 per share. In October 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. Including the new one million share repurchase authorization announced today, approximately 1.2 million shares are currently available for repurchase.

Mr. Boldt commented, “Our Board’s new one million share repurchase authorization reflects the company’s strong financial position and our continued confidence in CTG’s future prospects. In addition to our active share repurchase program, our commitment to delivering shareholder value is also reflected in our adoption earlier this year of a regular quarterly cash dividend.”

2013 Fourth Quarter and Full Year Guidance

CTG is providing guidance for the 2013 fourth quarter and full year in the table below. Based on year-to-date results and trends in its business, the Company has set guidance for the 2013 fourth quarter and adjusted its range of revenue and earnings guidance for the 2013 full year from previous guidance to reflect a reduction in the demand for resources on hospital EMR projects and for resource levels currently needed by a large staffing client.

2013 Fourth Quarter (65 billing days vs. 64 in Q4 2012)

2013 Full Year (Projected tax rate of 35% to 37%)

Mr. Boldt commented, “Although we are projecting revenue to decrease slightly compared to last year, we still expect earnings and margin growth for the full year, which is a solid performance given that overall spending in the IT services industry is constrained in 2013. Importantly, with the focus on our healthcare business and disciplined expense control, CTG continues to become a more profitable company with our operating margin moving into our strategic goal range of six to seven percent in the last two quarters despite some of the revenue challenges we are experiencing this year.”

Mr. Boldt concluded, “CTG’s robust offerings in EMR as well as other areas such as post-implementation EMR production support, application management outsourcing, and medical data analytics, all support cost and risk reduction for healthcare organizations. We are also continuing to grow our payer business and see strong potential there in our IT medical management model and our fraud, waste, and abuse software. With European countries just starting to implement U.S. EMR systems, CTG is very well positioned to capitalize on this major multi-year opportunity based on our significant U.S. EMR implementation experience and a large established European presence that includes etrinity, the health IT services firm we acquired earlier this year. This breadth of growth opportunity from multiple sources gives us great confidence that we will be able to continue building our healthcare IT business and advance CTG’s transformation to an IT services and solutions company with a focus on healthcare IT.”
