CTG Reports 2017 First Quarter Results

Executes on Long-term Growth Objectives; Appoints Chief Financial Officer;

Continues Significant Stock Buyback Program

BUFFALO, N.Y., April 25, 2017 – CTG (NASDAQ: CTG), an information technology (IT) solutions and services company, today announced its financial results for the first quarter ended March 31, 2017.

First Quarter Results

Recent Accomplishments to Drive Enhanced Shareholder Value

CTG Chief Executive Officer, Bud Crumlish, commented, “Our business performed well during the first quarter with both revenue and earnings at the mid-point of our guidance range as we continued to execute on our long-term strategic plan. Revenue from Solutions increased on a sequential basis, partially offset by an expected, modest decline in our Staffing business. The decline in Staffing was a result of the previous reduction in business at our largest staffing client. Highlighting the quarter, our business in Europe achieved sequential and year-over-year growth, setting a record in terms of percentage of total CTG revenue.”

Continued Implementation of the Key Elements of Three-Year Strategic Plan and ONE CTG Program

During the quarter, CTG added new Staffing clients targeted in the mid-market segment, which is a key element of the strategic plan to diversify the staffing client portfolio. In line with these objectives, the Healthcare organization has been focusing on enhancing CTG’s solutions offerings while pursuing staffing opportunities at healthcare clients. Overall, CTG is making progress in expanding its existing solutions across all lines of business as part of the ONE CTG program, which encourages collaboration and cross selling, announced and launched in early January. In the first quarter, the Company consolidated several solutions into a new comprehensive, global solution that is designed to maximize the value, efficiency, and cost effectiveness of the application management services it provides.

Mr. Crumlish continued: “I am encouraged by the traction we have achieved to-date across the organization to meet our milestones over the next three years as evidenced by the expansion of new accounts, further penetration at existing accounts as well as increased activity on prospective new engagements. Personally, I have been working directly with our sales teams and meeting with existing and potential new clients to demonstrate CTG’s full commitment to their ultimate success. The entire Company remains highly focused on execution against our strategic plan and financial objectives.”

Strengthened Leadership Team

Search for Chief Operating Officer

As CTG continues to expand its business in line with the three-year strategic plan, the CTG Board has recognized the importance of adding executive level leadership to drive business development and operational improvements. As a result, CTG is initiating a search for the position of Chief Operating Officer focused on driving new and existing business relationships, while also ensuring a more effective delivery and recruiting organization to provide the best value for its clients.

Consolidation of Chief Financial Officer and Treasurer Positions

A key element to the Company’s three-year strategic plan is disciplined cost management, which is evaluated on an on-going basis across the enterprise. As a result of an evaluation by CTG’s Board of the overall costs of the leadership team, the Board is promoting John Laubacker to the position of Senior Vice President, CFO and Treasurer upon the resignation by mutual agreement of Brendan Harrington.

CTG’s Chairman of the Board, Daniel J. Sullivan, commented, “The Board considers CTG fortunate to have had two highly experienced financial executive officers for many years. In light of our strategic objectives and our commitment to meet our milestones over the next three years, we have determined the time is right to make the leadership changes necessary by consolidating these two executive positions. We sincerely appreciate all of Brendan’s contributions in the multiple roles in which he has served for CTG, most recently as CFO. We wish him well in his future endeavors.”

Mr. Laubacker, a CPA, has been with CTG for 21 years. He was appointed Vice President and Treasurer in February 2017 after serving as Treasurer since 2006. He was CTG’s interim CFO from October 2014 to July 2015. Mr. Laubacker also held the positions of Director of Audit and Treasury Services and the Manager of External Reporting after joining the Company in 1996. Prior to joining CTG, he was a senior manager with KPMG.

Mr. Sullivan continued, “John has exhibited excellent command and a high level of expertise in all financial and operational areas of our business which makes this transition possible. The Board is excited to work with John in his new role.”

Continued Strengthening of Sales Team Across the Organization

In concert with our growth objectives, we continue to upgrade and optimize the sales team. During the quarter, we added multiple new sales individuals to increase our capacity as well as enhance the effectiveness of the team. The pursuit of highly skilled sales people within our industry with the expertise of staffing and solutions is an on-going process as we continue to build and strengthen our sales team to meet our long-term strategic goals.

Share Repurchase Program

During the first quarter, the Company repurchased 384,000 shares at an average price of $4.87 per share, or approximately $1.9 million in the aggregate. Since the announcement of the authorization in November 2016 and through April 24, 2017, the Company repurchased a total of 754,000 shares at an average price of $4.72 per share. At April 24, the Company had $6.4 million remaining under its existing repurchase authorization.

Consolidated First Quarter Results

Revenue in the first quarter ending March 31, 2017 was $77.0 million, compared with $77.5 million in the fourth quarter of 2016 and $85.9 million in the first quarter of 2016. Negative currency translation reduced revenue in the first quarter by $0.8 million, compared with a negative impact of $0.4 million in the fourth quarter of 2016.

Direct costs in the first quarter were $62.8 million, or 81.5% of revenue, compared with $62.6 million, or 80.8% of revenue in the fourth quarter of 2016, and $71.3 million, or 83.1% of revenue, in the year-ago first quarter. First quarter SG&A expense was $12.9 million, compared with $13.1 million in the fourth quarter of 2016 and $13.5 million in the first quarter of 2016.

The non-GAAP income tax rate in the first quarter of 2016, which excludes the impact of the goodwill impairment, was 32.4%. The higher effective tax rate in the first quarter of 2017 reflects the adoption of a new accounting standard, which required the Company to record approximately $0.1 million of additional tax expense related to employee stock-based transactions that previously would have been recorded to stockholders’ equity.
