Exhibit 99.1

March 10, 2021

Fellow CTG Shareholders:

Over the last year, we have all been subject to the unprecedented and difficult environment resulting from the global COVID-19 pandemic. We express our sympathies and well wishes to all those who have suffered hardship or loss. We also want to thank those who are working to protect and care for the wellbeing of all of the communities around the world in which we live and operate.

As we are a global enterprise, the COVID-19 pandemic created many challenges for us, but at the same time created multiple opportunities driven by the surge in the usage of digital technologies due to worldwide lockdowns and increasing work from remote locations. People and organizations all over the world have had to adjust to new ways of work and life, and our teams and capabilities are critical to enabling them to function in this ‘new world order’.

Despite the challenges across all industries and ultimately to the broader economy, our team delivered outstanding financial results during 2020. A few examples include Solutions revenue growth as a percent of our overall business mix, gross profit margin improvements and material earnings growth over 2019. Revenue from Solutions grew 5.4% to 37.8% of total revenue, while the gross profit margin on our Solutions business grew 5.7% to 27.3%, and our GAAP and non-GAAP net income grew 85% and 34%, respectively, year-over-year.

Our strong results for the year serve as an important validation that our existing solutions strategy is working and yielding the anticipated outcomes. To continue driving long-term success, we recently announced a major initiative to accelerate digital transformation (DT) services to our clients. This initiative will enable CTG to capitalize on significant market opportunities as we continue to invest in sales and business development resources, enhanced solutions offerings, and global delivery network capabilities.

Digital Transformation – Core of Solutions Strategy

The priority of our updated brand and new tagline, “Transformation Accelerated,” is to deliver digital solutions to our clients, enabling them to continue serving the evolving needs of their customers at the speed required for them to compete successfully.

Market disruptors are driving broad evolution and transformation, promoting social and economic change at a rapidly increasing pace. At CTG, we are focused on providing the technologies and methodologies to meet our clients’ evolving needs in areas such as Artificial Intelligence and machine learning to the Internet of Things and cloud computing platforms.

In light of the pandemic and the adoption of remote and digital work, businesses across most industries need to increase their focus on DT. We are operating in a fast-paced market with

significant demand where DT initiatives are viewed as a top business priority. Our strong geographic footprint and OneCTG focus allow us to capitalize on these changes and optimize a scalable global delivery network to create adaptable solutions for our clients while minimizing overall delivery costs.

2023 Vision

We have a unique competitive advantage as a trusted and reliable partner in today’s business landscape given our ability to swiftly provide solutions to our clients as promised. In today’s marketplace, the majority of digital technology projects fail to deliver their intended value. We see this as an opportunity to capitalize on our ability to deliver repeatable digital solutions faster, improve profitability, and solidify our position as a recognized expert for DT momentum and success.

As we continue to adapt to our clients’ evolving needs and provide them with the services and solutions they need to meet their own business challanges, we are confident in our ability to achieve the following objectives through 2023:

Exceptional 2020 Results in a Challenging Environment

This past year has put the execution of our strategy to the ultimate test and we are proud that we have delivered strong financial and operational results. Key highlights from the past three years include significant improvements in our non-GAAP operating margin, diluted EPS, adjusted EBITDA and solutions revenue as a percentage of total revenue:

Our exceptional performance throughout the year was also a result of the immediate actions we took at the outset of the pandemic. To reinforce the financial health of CTG, we:

As we progressed through the year, challenging operating conditions highlighted the importance of disciplined execution. In support of accelerating our digital solutions strategy, we continued to identify new opportunities to expand our capabilities and expertise and invest in CTG’s future as a leading accelerator of digital transformation.

We invested in key areas across our sales and business development organizations, developed new, innovative digital solutions offerings to expand our product portfolio, and expanded our Global Delivery Network capabilities to continue delivering high-quality, cost-effective business and IT services and solutions to our clients. Beyond these measures, we added to our highly talented global solutions group and now have a senior team comprised of eight leaders in design and delivery of DT services. New additions in the past fifteen months include:

Strategic Acquisitions Contribute to Enhanced Global Market Presence

In March 2020, we completed our acquisition of StarDust, a small but leading digital testing and quality assurance company with operations in France and Canada. This strategic transaction was immediately accretive to our operating results, and supported our strategy of expanding Global Testing DT Solutions across the geographies we serve. Through this transaction, we increased CTG’s presence in the high-growth global testing market, including the launch of application testing solutions in the United States and Canada.

With StarDust, our services now include crowdtesting providing a faster, more flexible testing solution that differentiates CTG from many of our competitors. Given the success of our recent investments through strategic acquisitions, we plan to continue to evaluate potential synergistic transactions that are accretive to earnings and provide opportunities to further accelerate our DT strategy.

Corporate Governance Enhancements

Corporate governance is a key aspect of our values-driven business operations and corporate culture. In 2020, the CTG Board focused on enhancing governance practices and diversifying its members in terms of gender, race, experience, skills and tenure.

In December 2020, we added Raj Rajgopal to the CTG Board, further expanding our expertise and commitment to maintaining a Board with diverse backgrounds and perspectives. Raj brings valuable experience to the Board in the implementation of digital strategies and a proven track record of leading business transformation.

As a result of Raj’s appointment, the CTG Board has temporarily expanded to seven directors until our 2021 Annual Meeting, at which time Dan Sullivan, current Chairman, will step down, consistent with the Company’s retirement age guidelines. At our 2021 Annual Meeting, the CTG Board will comprise of six directors, five of whom are independent and two of whom have been appointed over the last three years.

Additionally, following our annual review of Board compensation with a third party expert and in recognition of shareholder feedback, we made the decision to change independent director base compensation in 2021 to 40% cash and 60% stock from 100% stock in recent years.

Building on Our Positive Momentum

CTG’s success will continue to be driven by the primary objectives underlying our strategic plan, including to:

Although the COVID-19 pandemic continues, driving uncertainty in the markets in which we serve, we are excited with the momentum we have created during 2020, and we will not be slowing down. Our strong financial performance this past year demonstrates the disciplined execution of our strategic plan has been effective. We are further committed to executing on our 2023 vision, promoting transformational growth and positioning CTG as a premier global solutions provider. To that end, we continue to make the necessary investments to drive near- and long-term success, as we deliver on our absolute commitment of value creation for shareholders.

We are confident that CTG will successfully leverage its competitive advantage in the digital solutions space, differentiating our offerings from those of our competitors and meeting the ever-evolving needs of our clients.

On behalf of the CTG Board and management team, we thank you for your investment in CTG and the continued support that you have extended to us, especially over this past difficult year.

Reconciliation of GAAP to Non-GAAP Information

The Company has referenced non-GAAP information in this shareholder letter. 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, facilitating ongoing operating decisions, and measuring the Company’s overall performance. The Company believes that these non-GAAP measures align closely with its internal measurement processes and are reflective of the Company’s core operating results.

A reconciliation of GAAP to non-GAAP information is included in the financial tables below. The non-GAAP financial information is presented using a consistent methodology from year-to-year. These measures should be considered in addition to results prepared in accordance with GAAP. In addition, these non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles. The Company believes that non-GAAP financial measures have limitations in that they do not reflect all amounts associated with the Company’s results of operations as determined in accordance with GAAP and that these measures should only be used to evaluate the Company’s results of operations in conjunction with the corresponding GAAP financial measures. As such, the non-GAAP financial measures disclosed by the Company should not be considered a substitute for or superior to financial measures calculated in accordance with GAAP, and reconciliations between GAAP and non-GAAP financial measures included in this shareholder letter should be carefully evaluated.

The non-GAAP information below excludes gains from non-taxable life insurance and on the sale of a building, and costs associated with severance and certain acquisition-related expenses. The acquisition-related expenses consist of due diligence costs, amortization of intangible assets, and changes in the value of earn-out payments upon the achievement of certain financial targets from the Company’s recent acquisitions.
