Cingular Business Markets Group

Dear BMG Colleagues,

Our parents, AT&T and BellSouth, issued some very exciting news this week regarding their intention to merge. This transaction will go through a number of approvals, and our parent companies anticipate it will be completed in about a year. Announcements like this naturally raise questions and I wanted to reach out today to discuss how the merger affects Cingular, BMG and you as a BMG employee.

The merger is a very positive development for Cingular and our customers. It will create a stronger and more nimble company with simpler governance to accelerate time to market for converged wireless/wireline solutions. Our customers will benefit from a broader pool of resources and an expanded product set. Since Cingular currently represents the wireless assets of our two parent companies, we anticipate that Cingular’s wireless operations will remain largely unchanged, with headquarters in Atlanta.

BMG has established Cingular as a leader in B2B, with an unprecedented investment in enterprise-optimized business infrastructure and services, and unmatched wireless business expertise. Our parent companies recognize the value these capabilities will deliver.

During this time it is critical that each of you stay focused on your customers, BMG’s Priorities, the 4 R’s and your individual business goals. For those of you who were with us during the AT&T Wireless/Cingular merger, you will remember that we approached that transaction with a strong commitment to ensure a positive customer experience. It is imperative that we approach this merger with the same sense of professionalism.

In your customer conversations, concentrate on the business value we can deliver for them with wireless technology. When discussing the merger and its impacts, focus on what is known today and don’t speculate. BMG-specific talking points are included below to help you with questions from your customers. I also encourage you to visit additional resources on my-cingular to stay informed about the progress of the merger as more information becomes available.

I am extremely proud of what all of us in BMG have accomplished in the past year while we implemented many changes to our infrastructure and processes. You’ve done just a phenomenal job. Together we will continue to deliver on our commitment to be the best in the business.

I look forward to our continued success in the coming year and beyond.

Sincerely,

Kent Mathy
President, Business Markets Group
