History
The earliest predecessor of Lumen was the Oak Ridge Telephone Company in
Oak Ridge, Louisiana, which was owned by F. E. Hogan Sr. In 1930, Hogan sold the company, with 75 paid subscribers, to William Clarke and Marie Williams, for $500. In 1946, Clarke McRae Williams received ownership of the family's telephone company as a wedding gift. Clarke purchased the Marion Telephone Company and eventually made it his base of operation as he grew his company through more acquisitions. The company remained as a family-operated business until it became incorporated in 1968. It went public in 1978.
1967–1999
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.
In 1971, the company was renamed Century Telephone Enterprises, Inc.
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.
The company went public in 1978 on the New York Stock Exchange.
In 1985, Century Telephone sold several subsidiaries to Colonial Telephone for $4.66 million.
In 1987, the stock price rapidly increased from its low that year, before dropping in the
1987 stock market crash
Black Monday (also known as Black Tuesday in some parts of the world due to time zone differences) was a global, severe and largely unexpected stock market crash on Monday, October 19, 1987. Worldwide losses were estimated at US$1.71 trillion. ...
. Earnings grew each year from their 1983 low, and by 1987 they reached nearly US$20 million.
From 1991 to 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.
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. The company sold off some of its telephone assets to smaller competitors for hundreds of millions of dollars.
2000s
In 2000, the company acquired 490,000 telephone lines from

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.
In 2003 the company acquired Digital Teleport ($39 million) which then formed some of its main assets and expanded the company's fiber network offering.
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.
In 2005, CenturyTel began offering satellite television services. In 2007, CenturyTel acquired NC-based CLEC Madison River Communications which was also the parent company of four ILEC operations in NC (MebTel), GA (Coastal Communications), AL (GulfTel Communications) and IL (Gallatin River Communications). Also in 2007, a "workforce reduction" resulted in 600 employees laid-off as well as receiving $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 to 2007 CenturyTel repurchased approximately $2 billion in shares.
2008 merger with Embarq and name change to CenturyLink

On October 27, 2008,
Embarq
Embarq Corporation was the largest independent local exchange carrier in the United States (below the Regional Bell Operating Company, Baby Bells), serving customers in 18 states and providing local, long-distance, high-speed data and wireless s ...

Glen Post would remain CEO of the merged company following the acquisition,

. On June 2, 2009, a press release announced that the combined CenturyTel/Embarq entity would be called CenturyLink. Denver-based Monigle Associates was retained to formulate the new brand strategy. The acquisition was completed on July 1, 2009.
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.
2010 merger with Qwest
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.
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%. The valuation of CenturyLink's purchase was $12 billion.
The merger was completed on April 1, 2011.
The addition of Qwest allowed CenturyLink to become the third largest telecommunications company in the United States, and the largest

At the time, Tier 3 operated nine data centers in the Seattle region while Savvis operated 55. CenturyLink planned to build out two to four new datacenters in 2014. The CTO of Tier3, Jared Wray, took the CenturyLink Cloud CTO position after the acquisition. SavvisDirect was retired in 2014 as part of an internal consolidation of CenturyLink's cloud service offerings.
On December 8, 2014, CenturyLink announced the acquisition of DataGardens, Inc., a Disaster Recovery as-a-Service (DRaaS) provider based in Edmonton, Alberta, Canada.

After securing the necessary regulatory approvals, CenturyLink closed the transaction on November 1, 2017. This acquisition can now be viewed as a takeover from the inside. 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
SAP services provider. CenturyLink ended 2017 with $1.3 billion in net income.
By the end of 2018, CenturyLink had $35 billion in long term debt. It determined it had 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.

Effective with the opening of the trading day on September 18, 2020, the company stock ticker changed from CTL to LUMN. The CenturyLink brand will continue to be the customer-facing brand for traditional copper-based services. Fiber-based products and services use the brand ''Quantum Fiber''.
Lumen divestments
On August 3, 2021, Lumen announced it would sell its

for $7.5 billion.
Lumen structured the deal to retain their infrastructure in urban and suburban areas which they still wanted to upgrade from copper to fiber and sell-off areas that they deemed unworthy of further investment. Lumen retained ILEC operations in 16 states, mostly the operations formerly served by
Qwest.
The sale closed in October 2022; the sold ILEC operations were rebranded as
Brightspeed.
Lumen has won multiple government contracts. Throughout 2021, it won a managed network service contract with
United States Postal Service

and a connectivity contract with US Army Recruiting and the US Navy Judge Advocate General Corps.
Lumen continued to have difficulty generating profit in 2022. The executives divided the company in "Growth", "Nurture", "Harvest" sections. These corresponded to high margin, low-margin, and very-low/negative margin. The goal was to move customers from Nurture to Grow products and to sell off the Harvest products. Landline sales continued to fall but Lumen focused on growing the profitable fiber services. This led to the $2.7 billion sale of its Latin American business which was rebranded as Cirion.
In 2023, a deal was signed with
Colt Technology Services in which Lumen EMEA, its subsidiary serving the Europe, Middle East, and Africa enterprise markets, would be sold to Colt for $1.8 billion.
The deal allows Lumen to continue serving multinational enterprise customers via Colt's infrastructure.
In May 2025, Lumen announced an agreement to sell its consumer fiber business to

service to be disrupted across the country. In some areas the outage lasted nearly twelve hours and was the third shutdown of the year following outages in April and November 2018. ATM and point of sale credit card machines were also widely affected.
The outage resulted in 886 calls to 911 failing to deliver. The FCC investigated but did not place any fine or recommendation on Lumen.
In 2020, 911 outages in South Dakota, North Dakota, Minnesota, Colorado, Arizona, Utah and North Carolina led to additional FCC investigations. Lumen agreed to pay $3.8 million in civil damages for failing to deliver 911 calls.
In 2022, additional outages, in South Dakota, resulted in a criminal finding from the FCC:
An investigation by the FCC’s Enforcement Bureau found that Lumen apparently willfully and repeatedly violated FCC rules by failing to notify public safety call centers in a timely manner of both 911 outages and by deploying a system that was insufficient to transmit all 911 calls reliably to public safety call centers in the second outage, creating a significant threat to the life and property of tens of thousands of people.
In 2023, outages on Lumen's network, in Nebraska, resulted in no 911 calls being fulfilled for over 10 hours.
In 2024, there were multiple 911 service disruptions in South Dakota. The FCC announced additional investigation into these outages. In these outages local officials claim service was not disrupted because the texting system was still operational.
