The deal closed on November 1, 2017, turning Level 3 into an indirect wholly owned subsidiary and creating the network platform that later operated under the Lumen Technologies name.
The headline made strategic sense: CenturyLink brought a large enterprise customer base and U.S. infrastructure, while Level 3 added global fiber, IP and enterprise-connectivity assets. But the outcome depended on more than network scale. Price, leverage, regulatory approvals and difficult systems integration all mattered.
1. The $34 billion figure included debt
The announced enterprise transaction value was approximately $34 billion, including debt CenturyLink assumed or refinanced. It was not a $34 billion cash payment to Level 3 shareholders.
| Measure | Announced detail |
|---|---|
| Enterprise transaction value | Approximately $34 billion, including assumed debt |
| Cash consideration | $26.50 for each Level 3 common share |
| Stock consideration | 1.4286 CenturyLink shares for each Level 3 share |
| Implied value at announcement | Approximately $66.50 per Level 3 share, using CenturyLink’s $28 reference price |
| Announced premium | Approximately 42% over Level 3’s unaffected October 26, 2016 close |
The company’s announcement describes the valuation and premium at Lumen’s transaction release. Enterprise value and equity value are different measures, so they should not be used interchangeably.

2. Level 3 holders received both cash and stock
Under the merger agreement, each Level 3 common share was exchanged for $26.50 in cash plus 1.4286 CenturyLink shares. The 1.4286 exchange ratio was fixed; it was not adjusted if CenturyLink’s share price changed before closing.
- If CenturyLink shares fell, the stock portion would be worth less to Level 3 holders.
- If CenturyLink shares rose, that portion would be worth more.
- Fractional CenturyLink shares were paid in cash.
- Specified equity awards, including certain restricted-stock-unit awards, had separate cash-and-stock treatment under the agreement.
The exchange mechanics and award treatment are set out in the joint proxy statement and prospectus.
3. The premium was substantial—but it was a signing-date comparison
CenturyLink said the consideration represented about a 42% premium to Level 3’s unaffected closing price of $46.92 on October 26, 2016. “Unaffected” means the comparison used a price before deal speculation and the announcement, not a guaranteed return for investors after signing.
The approximately $66.50 implied value also depended on the $28 CenturyLink reference price. Because part of the consideration was stock, the final market value experienced by Level 3 holders moved with CenturyLink’s shares until the transaction closed.

4. CenturyLink was buying global enterprise-network reach
Management presented the companies as complementary. CenturyLink had a substantial enterprise customer base and domestic network assets. Level 3 operated a broad global fiber, IP, data-network and carrier footprint.
The stated rationale was to give CenturyLink customers wider international reach and to cross-sell Level 3’s connectivity and network services. The companies also pointed to opportunities in enterprise communications, cloud connectivity, managed services and high-capacity broadband infrastructure—areas growing as traditional voice services declined.
These were management’s strategic objectives, not guaranteed results. A complementary network can support sales growth only if products, pricing, service quality and customer relationships survive the combination.
5. More than 60 countries meant scale—and complexity
Transaction materials described a combined presence in more than 60 countries. That footprint could improve the companies’ ability to serve multinational enterprises, carriers, government customers and wholesale buyers.
Geographic reach did not mean every product was available on identical terms in every country. Routes, facilities, licenses, local partners and regulatory requirements differed. The commercial value therefore depended on how much of the footprint could be packaged and sold as reliable end-to-end service.
6. Financing and leverage were as important as the strategy
The cash-and-stock structure limited the need to fund the entire purchase with cash, but the transaction still involved assumed or refinanced debt and financing commitments. The merger materials identify commitments involving Bank of America Merrill Lynch and Morgan Stanley.
After closing, management had to balance several competing demands:
- service and network investment;
- interest payments and debt reduction;
- the dividend expectations associated with CenturyLink’s shareholder base; and
- the one-time costs of combining two large telecom operators.
That is why leverage was a central deal risk. Even a strategically attractive acquisition could destroy value if debt constrained investment or forced unfavorable financial decisions while legacy services continued to decline.

7. Approval took longer than the original timetable
The transaction required CenturyLink shareholder approval to issue shares, Level 3 shareholder approval of the merger agreement and regulatory clearance. The 2016 announcement anticipated a closing in the third quarter of 2017. The actual closing occurred on November 1, 2017.
The legal agreement used successive mergers. First, a CenturyLink merger subsidiary merged into Level 3, with Level 3 surviving as a CenturyLink subsidiary. A second merger then placed Level 3 under another CenturyLink merger subsidiary, producing an indirect wholly owned subsidiary. This structure explains how a transaction described as an acquisition could still deliver CenturyLink stock to Level 3 investors. The definitive structure appears in the Agreement and Plan of Merger.
The completion announcement confirms the November 1 closing date: CenturyLink completes acquisition of Level 3.

Closing made the transaction legally complete; it did not prove that every forecast was achieved. Integration required combining network-management systems, product catalogs, billing platforms, sales teams and operating cultures while keeping customer service stable.
Execution risks
- Systems or network changes could cause outages, billing errors or slower service delivery.
- Product rationalization could confuse customers or weaken relationships.
- Cross-selling could arrive later—or cost more—than projected.
- Employee departures could remove technical and sales expertise.
- Pricing pressure and overlapping customer relationships could reduce expected returns.
- Debt could limit flexibility if operating performance weakened.
Level 3 became part of CenturyLink rather than remaining a separate public company. CenturyLink later rebranded as Lumen Technologies in 2020; the post-closing history is documented in the company’s filings, including its 2019 Form 10-K. The acquisition therefore created the foundation of today’s Lumen network, but the existence of that platform alone does not establish that all original synergy or shareholder-return goals were met.
How to judge the deal
A useful assessment separates five questions:
- Strategic fit: Did CenturyLink’s customer relationships and Level 3’s network assets complement one another?
- Price discipline: Did the expected growth and synergies justify the premium?
- Balance-sheet resilience: Could the combined company fund investment, dividends and debt reduction?
- Integration feasibility: Could systems and operations be combined without damaging service?
- Industry timing: Would enterprise data and cloud connectivity grow faster than legacy voice services declined?
On the first question, the rationale was clear. On the others, success depended on execution after November 2017, not on the announcement’s projections.
The Bottom Line
CenturyLink’s Level 3 purchase was a roughly $34 billion enterprise-value bet on scale, global connectivity and enterprise networking. The combination was strategically logical, but the fixed-stock consideration, substantial financing needs and complex integration meant that owning more fiber and serving more than 60 countries was only the starting point.
