Consolidated Communications was founded as the Mattoon Telephone Company in 1894 by Dr. Iverson A. Lumpkin in Mattoon, Illinois. In 1924, the company became the Illinois Consolidated Telephone Company (ICTC) and began acquiring telephone companies in the region over the next several decades, including telephone companies in
Christian County,
Montgomery County, the Illinois Southeastern Telephone Company and the
Effingham, Illinois, exchange from
Illinois Bell. In 1984, Consolidated Communications, Inc. (CCI) was formed as the parent company of ICTC, Consolidated Communications Directories and Consolidated Market Response. In 2002, five years after CCI merged with
McLeodUSA, the firm was acquired by a group of investors led by ICTC Chairman and President Richard A. Lumpkin, and its name was changed to Consolidated Communications. In December 2024, Consolidated Communications Holdings, Inc., announced that it had completed its merger with Condor Merger Sub Inc., a subsidiary of Condor Holdings LLC, with investment funds managed by
Searchlight Capital Partners and
British Columbia Investment Management Corporation. As a result of the merger, the board of directors of Consolidated Communications resigned, and the directors of Condor Merger Sub Inc. took over the roles. In September 2025, Consolidated Communications Holdings, Inc. finalized its rebrand to Fidium. == States ==
