Overview
On June 13, 2016, Microsoft agreed to buy LinkedIn for $196 a share in cash, about $26.2 billion including LinkedIn’s net cash. At the time it was the largest acquisition Microsoft had ever made.
The deal closed on December 8, 2016, after clearance in the United States, the European Union, Canada, Brazil and South Africa.
Most buyers that pay that much for a platform start merging it on day one. Microsoft did the opposite: it connected LinkedIn to its products and left the network itself alone. Nine years later, LinkedIn brings in almost six times the revenue it did before the deal.
Why Microsoft bought LinkedIn
Microsoft owned the place where professionals work: Outlook, Office 365 and Dynamics. It did not own who those professionals were or who they knew.
LinkedIn did. At the announcement, it had more than 433 million members, up 19% in a year, and more than 105 million unique visitors each month. Satya Nadella framed the deal as a way to “accelerate the growth of LinkedIn, as well as Microsoft Office 365 and Dynamics.”
That is a capability acquisition, not a cost play. The professional graph could not be built in-house at any reasonable price or speed, which is the test a corporate development team should apply before paying a platform premium.
For LinkedIn, the logic was certainty. Co-founder and controlling shareholder Reid Hoffman backed the deal publicly, and both boards approved it unanimously.
What Microsoft paid for LinkedIn
Microsoft paid all cash and funded it mainly with new debt, including a $19.75 billion bond sale in August 2016, then its largest ever. It told investors to expect about 1% dilution to non-GAAP earnings per share through fiscal 2018 and accretion in fiscal 2019.
The market was skeptical at first. LinkedIn’s shares rose about 47% on the announcement, while Microsoft’s fell about 3%.
| Deal term | Figure |
|---|---|
| Announced | June 13, 2016 |
| Closed | December 8, 2016 (about six months) |
| Price | $196 per share, all cash |
| Headline value | About $26.2 billion, including LinkedIn’s net cash |
| Purchase price recorded at close | About $27.0 billion |
| Financing | Mainly new debt, including a $19.75 billion bond sale |
| Goodwill recorded | About $16.8 billion (62% of the purchase price) |
| Expected earnings impact | About 1% dilutive through fiscal 2018, accretive in fiscal 2019 |
At close, Microsoft recorded a $27.0 billion purchase price. About $16.8 billion went to goodwill and $7.9 billion to intangible assets.

Goodwill is a promise that future cash flow will justify the premium. At 62%, LinkedIn’s share was high but lower than the 76% in our Salesforce–Slack case study. Testing that promise before signing is the job of M&A due diligence.
The Microsoft LinkedIn integration: connect, don’t absorb
The structure was set before close. Microsoft said LinkedIn would “retain its distinct brand, culture and independence,” and Jeff Weiner stayed CEO, reporting directly to Nadella.
That choice kept the people who ran the network in charge of it. It is the opposite of assuming founders will stay, and it is why HR due diligence should map who runs the asset and how they will report after close.
Regulators added guardrails. To win EU clearance, Microsoft made five years of commitments: rival professional networks kept access to Office, users could switch off LinkedIn data in Office, and PC makers could leave a LinkedIn app off Windows.
Then came the product links, and they were light. In 2017 Microsoft paired Sales Navigator with Dynamics 365 for social selling and added a LinkedIn profile card to Office 365. Those are the kind of revenue synergies a go-to-market integration should chase first: they help the customer without touching the product’s core.

Even the infrastructure stayed put. Microsoft announced in 2019 that LinkedIn would move onto Azure, but LinkedIn paused the migration in 2022 and kept its own data centers. A forced move would have spent engineering time on the acquirer’s priorities instead of the product.
That is a useful rule for any IT integration: migrate a system because it creates value, not because the parent owns a platform.
Leadership changed on a planned schedule. In June 2020, Weiner became executive chairman and product chief Ryan Roslansky became CEO, three and a half years after close. The successor came from inside LinkedIn, so the culture carried on. That matters because culture is where most integrations fail.
Microsoft did not buy a social network to run it. It bought a professional graph and put it next to the tools people already used.
Where the Microsoft LinkedIn acquisition stands in 2026
The growth showed up early. In the fourth quarter of fiscal 2018, LinkedIn revenue rose 37% and sessions rose 41%, and full-year revenue reached $5.3 billion.
It kept compounding. LinkedIn revenue was $16.4 billion in fiscal 2024 and $17.8 billion in fiscal 2025, up 9%. That is nearly six times LinkedIn’s roughly $3.0 billion of revenue in 2015, its last full year before the deal.

The network grew with it. LinkedIn now reports more than one billion members, more than double the count at announcement.
The closest parallel in our library is NVIDIA’s acquisition of Mellanox: another buyer that paid for a capability it could not build and protected it after close.
The payoff came from compounding the asset, not from cutting its costs.
What private equity firms should take from the Microsoft LinkedIn acquisition
Most private equity add-ons are bought for earnings. This deal is a reminder that a target’s most valuable asset may be something that is not yet in its EBITDA: data, a network, or the trust of its users.
The core lesson: a platform deal works when the acquirer preserves trust while making the core product smarter.
| Lesson | What Microsoft did | What to do before close |
|---|---|---|
| Buy what you cannot build | Paid for a professional graph it could not create in-house | Test in diligence whether the target’s data or network is scarce and how it plugs into your core |
| Protect what you paid for | Kept LinkedIn’s brand, culture and CEO, with a direct line to Nadella | Set leadership, decision rights and retention terms in the HR integration plan |
| Integrate at the edges first | Shipped product links in 2017 and paused the move to Azure | Sequence revenue links before back-office and system changes in the 100-day integration plan |
| Treat trust as an asset | Accepted five years of EU commitments on openness and user choice | List the customer, user and regulator promises the deal depends on, and give each an owner in the post-merger integration plan |
Compare Salesforce and Slack, where the promise of independence lasted about 18 months, or Broadcom and VMware, where every decision moved at full speed. Microsoft chose the pace decision by decision. That is easier when one team runs diligence, integration and value tracking through an end-to-end M&A capability.
