By 1967, Oak Ridge Telephone Company served three states with 10,000 access lines. That year, the company was incorporated as Central Telephone and Electronics. Clarke M. Williams served as president and chairman of the board.[7]

In 1971, the company was renamed Century Telephone Enterprises, Inc.[7] In 1972, Century Telephone acquired the La Crosse Telephone Corporation, of Wisconsin. This began a multi-decade spree of acquisitions which grew the size of the company.[8] The company went public in 1978 on the New York Stock Exchange.[7]

In 1985, Century Telephone sold several subsidiaries to Colonial Telephone for $4.66 million.[9]

In 1987, the stock price rapidly increased from its low that year, before dropping in the 1987 stock market crash. Earnings grow each year from their 1983 low, and by 1987 they reached nearly US$20 million.[10]

From 1991-1995 the company continued its acquisition strategy which added tens of thousand of phone lines and grew the long term debt from $205 million to $602 million with $115 million in annual net income. By 1995 it was the 16th largest communications company in the United States with over 3000 employees. Two hundred employees were unionized through the Communications Workers of America. [11]

In 1997 the company bought Pacific Telecom for $1.5 billion. This acquisition added 1.9 million cell lines to Century's network and nearly doubled the size of the company. After the acquisition Century's network served 21 states and 2 million customers.[12] The company sold off some of its telephone assets to smaller competitors for hundreds of millions of dollars.[13][14]

In 2000, the company acquired 490,000 telephone lines from Verizon for $1.5 billion. It then sold "substantially all" of its wireless business to AllTell for $1.59 billion in 2002. Through 2002 the company grew to nearly 7000 employees with approximately 1500 of them organized in various unions. At this time the company had about $800 million in net income and $3.6 billion in debt.[15] In 2003 the company acquired Digital Teleport ($39 million) and Level 3 communications ($16 million) which then formed some of its main assets and expanded the company's fiber network offering.[8] By 2004, CenturyTel was the eighth largest local telephone provider in the United States. In this time it paid down its long term debt to $2.7 billion and its net income fell to $337 million annually. [16] In 2005, CenturyTel began offering satellite television services. In 2007, "workforce reduction" resulted in 600 employees laid-off and received $336 million in Federal and State subsidy. CenturyTel received an additional $333 million the previous year. Most of these funds were received through the "High Cost Support Loop" program. From 2004-2007 CenturyTel repurchased approximately $2 billion in shares.[17]

On October 27, 2008, Embarq announced that it would be acquired by CenturyTel, Inc. in an all-stock transaction valued at about $6 billion.[18][19] CenturyTel's CEO Glen Post would remain CEO of the merged company following the acquisition,[20] and remained CEO until 2018.[21] Embarq was the former landline business of Sprint and served cities in 18 states, including Nevada, Florida, North Carolina, and Ohio.[22] The deal made CenturyTel the third-largest landline phone provider in Pennsylvania behind Verizon (through both Verizon Pennsylvania and Verizon North) and Comcast. On June 2, 2009, a press release announced that the combined CenturyTel/Embarq entity would be called CenturyLink.[23] Denver-based Monigle Associates was retained to formulate the new brand strategy. The acquisition was completed on July 1, 2009.[24]

On October 19, 2009, CenturyTel and Embarq brandings were retired, and all business was officially conducted under the CenturyLink banner, continuing to trade on the NYSE under the CenturyTel stock ticker CTL. The new corporate name, CenturyLink, Inc., did not become official until May 2010.[25][26]

On April 22, 2010, CenturyLink (at this point still legally known as CenturyTel, Inc.) announced it would acquire Qwest in a stock-for-stock transaction.[27] Under the agreement, CenturyLink would swap 0.1664 of its shares for each share of Qwest; as a result, CenturyLink shareholders prior to the merger wound up with 50.5% share of ownership in the combined company, while former Qwest shareholders gained the remaining 49.5%.[28] The valuation of CenturyLink's purchase was $12 billion.[18] The merger was completed on April 1, 2011.[29][30][31]

The addition of Qwest allowed CenturyLink to become the third largest telecommunications company in the United States, and the largest landline phone provider in the state of Colorado.[21] The new company has 17 million access lines, 5 million broadband customers, and 1.4 million video subscribers across 37 states.[32] The merger also made CenturyLink owner of one of the Former Regional Bell Operating Companies: the successor to US West, which had been purchased by Qwest in 2000.[33]

On July 15, 2011,[22] CenturyLink acquired Savvis, Inc., a global provider of cloud infrastructure and hosted IT services for $2 billion, which represented all outstanding shares of Savvis common stock at $40 per share.[18][34] This acquisition allowed CenturyLink to provide expanded managed hosting and cloud services.[35]

On December 4, 2012,[36] CenturyLink launched an integrated suite of cloud services called Savvisdirect.[37] Savvisdirect was an expansion of CenturyLink's portfolio of Savvis cloud services and includes cloud application hosting,[38] cloud servers,[39] cloud storage,[40] and private cloud[41] for small businesses, IT administrators, and developers. CenturyLink later shuttered the savvisdirect subsidiary, consolidating their cloud service offerings internally.

On October 16, 2012, Savvis acquired the ITO Business Division of Ciber, thereby adding managed services to the portfolio.[42]

On June 14, 2013, CenturyLink announced the acquisition of AppFog, a Portland-based Platform as a Service provider, used by over 100,000 developers to automate the deployment of software on public clouds, such as Amazon Web Services and OpenStack.[43]

Level3 shareholders would only approve the deal if CenturyLink retired their CFO and eventually CEO. Eventually all former CenturyLink executives would be replaced by former Level3 managers leaving only HR and legal executives in place.

On January 9, 2017, CenturyLink announced the acquisition of Edison, New Jersey-based SEAL Consulting, a leading SAP services provider. This expanded CenturyLink's existing integrated SAP capabilities of hosting and managed services to include integration and software implementation.[51] CenturyLink ended 2017 with $1.3 billion in net income.[52]

By the end of 2018, CenturyLink had $35 billion in long term debt. It determined it has overestimated the value of its goodwill and wrote down a $2.7 billion loss. This resulted in a $1.7 billion loss in net income for 2018.[52]

On August 3, 2021, Lumen announced it would sell its incumbent local exchange carrier (ILEC) operations in 20 states to Apollo Global Management for $7.5 billion.[56] The assets being sold are located in Alabama, Arkansas, Georgia, Illinois, Indiana, Kansas, Louisiana, Michigan, Mississippi, Missouri, New Jersey, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, and Wisconsin. Essentially, Lumen was jettisoning the core of the old CenturyTel and Embarq, including its assets in its home state of Louisiana. Lumen will retain ILEC operations in 16 states, including Florida, Nevada, and the states formerly served by Qwest: Arizona, Colorado, Idaho, Iowa, Minnesota, Montana, Nebraska, New Mexico, North Dakota, Oregon, South Dakota, Utah, Washington, and Wyoming.[57] The sale closed in October 2022; the sold ILEC operations were rebranded as Brightspeed.[58]
