2013 U.S. Incumbent Carrier Ethernet LEADERBOARD

AT&T, Verizon, CenturyLink, and Windstream attain Incumbent Carrier LEADERBOARD positions

BOSTON, MA, MARCH 21, 2014 ā€“ The topĀ four IncumbentsĀ sellingĀ Carrier Ethernet services in the U.S. are as follows (in rank order based on port share):Ā AT&T, Verizon, CenturyLink, and Windstream, according to Vertical Systems Groupā€™s latest research. These companies have achieved positions on Verticalā€™s 2013 U.S. Incumbent Carrier Ethernet LEADERBOARD, the benchmark for measuring Ethernet market presence based on billable retail ports delivered by Incumbent Carriers.

ā€œIncumbent Carrier is the most sizeable of the three U.S. Ethernet provider segments, but the slowest growing. Market leaders AT&T and Verizon have successfully nurtured their large enterprise and global customers with Ethernet-enabled solutions, while encountering more aggressive competition in the mid and small business markets across the U.S.,ā€ said Rick Malone, principal at Vertical Systems Group. ā€œBoth CenturyLink and Windstream, with improved Ethernet service delivery and sales execution, grew faster in 2013 than the two market leaders.ā€

Each company on the 2013 U.S. Incumbent Carrier EthernetĀ LEADERBOARD has achieved either a Leaderboard rank or a Challenge Tier citationĀ on the 2013 U.S. Carrier Ethernet LEADERBOARD.
