Revenue Grew 22% Over Last Year and Exceeded High-end of Guidance

EPS Met Midpoint of Guidance Range

BUFFALO, N.Y., July 19, 2018 – CTG (NASDAQ: CTG), a leading provider of information technology (IT) solutions and services in North America and Western Europe, today announced its financial results for the second quarter ended June 29, 2018.

Second Quarter Financial Summary

Second Quarter and Recent Business Highlights

CEO Comments on Financial Results and Strategic Growth

“Consolidated revenue grew 12% sequentially and 22.7% year-over-year to $92.7 million, which was above the high-end of guidance,” stated Bud Crumlish, CTG President and CEO. “Our results were driven by a combination of strong organic growth in both Staffing and Solutions as well as the first full quarter of revenue contribution from Soft Company, which was acquired in mid-February. Second quarter GAAP and non-GAAP earnings per share were at the midpoint of guidance, reflecting improved profitability resulting from targeted investments made in our sales organization, and the Soft Company acquisition, offset by certain acquisition-related expenses.

“We continued to experience solid growth and momentum in our European operations. The performance of Soft Company has been strong and our integration efforts remain on plan as we continue to increase the collaboration across our sales and administrative teams. Our teams in Belgium and Luxembourg also delivered strong results, including the ramp up of several previous wins, and two significant multi-year contracts with the European ministries that will begin to contribute to Europe’s overall results late in 2018.

“During the quarter, we completed the transition of more than 350 additional service desk employees at our largest Staffing client, while initiating work on several recently secured Staffing contracts. In our Solutions business, we began providing services to eight new healthcare clients, which included sizable contracts with Catholic Health Initiatives (CHI) and a prominent university medical center. This growing activity with new clients, combined with expanded bookings at existing clients, represent meaningful progress on our efforts to reposition and renew growth in our Healthcare Solutions business. In further support of this initiative, during the quarter we expanded CTG’s offerings with the launch of our newest enterprise information management solution, EIM Advantage, which enables clients to utilize the value of their data to capture, manage, analyze, and transform it into actionable information.

“In keeping with our objective to deliver increasing shareholder value, we successfully completed a tender offer in April that resulted in the repurchase of approximately 1.5 million CTG shares. At the same time, our board of directors authorized an expansion of our share repurchase program by $10 million, of which $8.9 million remained available at quarter-end. In addition, to further demonstrate our commitment to best-in-class corporate governance, our shareholders will vote next week on a proposal to declassify our board of directors.”

Mr. Crumlish concluded, “As reflected by our second quarter results, we are making significant progress on our strategic growth initiatives across the organization as previous investments in business development are contributing to CTG’s increasing revenue and improved profitability. In addition to building a healthy pipeline of new business opportunities, we are focused on driving increased efficiencies, while utilizing operating leverage to drive future profitability.”

The lower effective tax rates for the 2018 periods reflect the reduction in the U.S. statutory rate that became effective at the beginning of the year.

Balance Sheet

Cash and short-term investments at June 29, 2018 were $9.7 million, and the Company had $6.3 million in long-term debt. Days sales outstanding were 81 days in the second quarter of 2018, compared with 82 days in the second quarter of 2017.

Reconciliation of GAAP to Non-GAAP Information

The Company has referenced non-GAAP information in this news release. The Company believes that the use of non-GAAP financial information provides useful information to investors and management to gain an overall understanding of its current financial performance and prospects. In addition, non-GAAP financial measures are used by management for forecasting and facilitating ongoing operating decisions, as well as measuring the Company’s overall performance. The Company believes that these non-GAAP measures align closely to its internal measurement processes and are reflective of the Company’s core operating results.

Specifically, the non-GAAP information for the second quarter and year-to-date periods of 2018 as presented exclude certain acquisition-related expenses that the Company believes are not indicative of its core operating results. The reconciliation of GAAP to non-GAAP information for the second quarter ended June 29, 2018 is as follows:

Guidance and Outlook

CTG provided the following guidance for the 2018 third quarter and full year:

Acquisition-related expenses and amortization of acquisition-related intangible assets are excluded from non-GAAP guidance for diluted EPS.

John M. Laubacker, CTG’s Chief Financial Officer, commented, “We remain very optimistic about future growth given the recent ramp up of new business and our robust pipeline of opportunities. As a result, we have increased the midpoint of our full year revenue guidance for 2018. However, we have lowered our GAAP and non-GAAP diluted EPS guidance for 2018 as we continue to make significant investments in business development and recruiting to further enhance growth and profitability in the long-term. In addition, our third quarter revenue and earnings guidance reflect typical seasonality related to summer vacations, primarily in our European operations, which now represents approximately 35% of consolidated revenue. Given the current forecast for utilization and billable time in Europe, the impact from seasonality in the third quarter is expected to be more pronounced than in prior years. Over the coming quarters, we expect to make further progress toward our three-year financial plan and remain committed to achieving our long-term goals and financial targets in 2019.”
