SUBJECT: Exciting News About CTG’s Next Chapter

Dear [Name],

I wanted to be the first to share some exciting news with you about an important new chapter at CTG. We have recently entered into an agreement to be acquired by Cegeka, a leading IT solutions company. For additional details, please see our official press release on CTG.com.

Founded in 1992 by Andre Knaepen, Cegeka is headquartered in Hasselt, Belgium. They are a successful, profitable, and rapidly growing IT solutions leader led by CEO Stijn Bijnens. Cegeka currently employs over 6,000 IT professionals and has operations in 13 countries.

While we will be joining the Cegeka Group, we are not changing our focus or who we are as a company, and Cegeka is well-aligned with our strategy. We are confident that this transaction is a positive development for CTG and its clients and partners.

The combination of CTG and Cegeka is expected to create a global IT solutions organization with an even more robust portfolio of integrated end-to-end solutions, supported by an expanded Global Delivery Network and innovative technologies and digital accelerators. Together, we will have operations in 18 countries and become over 9,000 strong.

Today, it’s business as usual at CTG. Our clients, partners, and employees remain our top priority. We remain committed to providing the same level of services and solutions to our clients and you as an important partner.

On behalf of the entire CTG team, we thank you for your continued partnership and trust as we take this exciting step forward.

If you have any further questions, please don’t hesitate to reach out.

Sincerely,
