Frequently Asked Questions for GDIT Managers

The following questions and answers have been prepared to help GDIT managers understand more about the merger with CSRA and what it means for the company, our people, our customers and our business partners.

The Transaction and General Dynamics / GDIT

Q. Why did we take this action to merge with CSRA?

A. The government IT services market is in the process of consolidating. Today, our customers are increasing the overall number of large contracts, placing a premium on the requirement for increased scale and mass. The acquisition of CSRA represents a significant strategic step in expanding the capabilities and customer base of GDIT.

CSRA is an excellent fit within GDIT. They are an outstanding provider of innovative, next-generation IT solutions with industry-leading margins. We share many of the same customers, offer similar solution sets and have complementary portfolios. This combination brings together two industry leaders, and together, we will have greater scale to go after the largest new programs.

The combination of GDIT and CSRA will result in a $9.9 billion company with 45,000 employees. It will also position GDIT as the premier provider of high-tech IT solutions to the Government Technology Services market.

Q. How compatible is CSRA’s culture with our own?

A. 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 both share similar core values, including a culture deeply rooted in highly ethical behavior and operational excellence. Both companies also share a commitment to creating a positive impact in our local communities as reflected in our common support for military communities, philanthropy and volunteerism.

Q. What is the timing for the transaction?

A. As part of the transaction, General Dynamics has commenced a cash tender offer to purchase all of the outstanding shares of CSRA common stock for $41.25 per share in cash. The tender offer is subject to customary conditions, including the tender of a majority of the outstanding shares of CSRA common stock. General Dynamics has secured all necessary regulatory approvals to complete the acquisition in early April, assuming the successful completion of the tender offer that is scheduled to expire on April 2. We are now in the midst of planning for the integration of GDIT and CSRA.

Q. What impact will this transaction have on my employees and me?

A. We expect minimal operational impact to employees working on contracts supporting our customers before, during and after the transaction closes. Detailed discussions still need to occur to determine the potential impacts on indirect staff positions but we feel our larger company will provide employees with greater opportunities to grow their careers as we add to our technological capabilities and program portfolio.

During this interim period, we are still required to operate as separate companies and it is imperative that our employees remain focused on continuing to serve our customers.

How does this affect GDIT’s operations?

Q. Will we remain named General Dynamics Information Technology (GDIT)?

A. Yes. Our name will not change.

Q: Will the CSRA name change because of the acquisition?

A: After the closing of the acquisition, the CSRA business will be part of the GDIT Business Unit, and CSRA will refer to itself as General Dynamics Information Technology or General Dynamics IT.

Q. How will CSRA identify itself in legal or contractual documents and correspondence after the acquisition?

A: Similar to GDIT, CSRA consists of several legal entities. Those legal entities will exist post-closing and will not be immediately changed. Therefore, when the legal name of an entity is required to be used on a legal or contractual document, the proper full legal name should be used (for example on an NDA, teaming agreement, contract, license, etc.). CSRA will present itself to the market and to our customers as GDIT. Contact your supervisor or contracts management for clarification as needed.

Q. Will our organizational alignment and reporting structure change?

A. At this juncture, details on organizational alignment and reporting structure are still being determined. When the acquisition is final you will hear more about the important roles everyone has to play to ensure our companies come together seamlessly.
