Subject:          General Dynamics to acquire CSRA

This morning, General Dynamics announced that it has entered into an agreement to acquire CSRA. Once the transaction is complete, CSRA will be combined with GDIT.

CSRA is an excellent fit with GDIT. Together, we will have greater scale to go after the largest new programs and, with our combined skills we will develop the best in next-generation technologies to reduce customer costs and increase their mission capability. Moreover, our larger company provides employees with greater opportunities to grow their careers as we add to our technological capabilities and program portfolio.

This is an exciting time for our company! General Dynamics is making a significant investment in GDIT and we look forward to all that CSRA will bring. With 19,000 employees, CSRA serves customers across the defense, intelligence and federal civilian government markets. The company’s offerings complement and enhance GDIT’s strengths in our core lines of business, including IT solutions, cybersecurity and professional services.

Much like GDIT, CSRA is an organization with a strong reputation for serving customer mission requirements and earning trust through consistently delivering on their promises. We also share similar core values, including a culture deeply rooted in highly ethical behavior.

General Dynamics expects to complete the acquisition in the first half of 2018. In the meantime, I ask each of you to remain focused on continuing to serve our customers. During this interim period, we are required to operate as separate companies.

When the acquisition is final, and integration efforts can begin, you will hear more about the important roles everyone has to play to ensure our companies come together seamlessly.

I know that working together, we will accomplish great things.
