In January 2022 Microsoft announced it was buying Activision Blizzard for $68.7 billion. When the deal closed twenty-one months later, Microsoft recorded the purchase at $75.4 billion. Nobody renegotiated the price, and the per-share figure never moved from $95.00.
The $6.7 billion difference is enterprise value doing exactly what it is designed to do, and it explains why the measure exists. Market capitalization prices the shares. Enterprise value prices the business, which is a different thing when the business is carrying debt and sitting on cash.
The Components, and What Each One Is Doing
The formula put to the SEC on the public record, in a comment letter the Commission reproduced in its 2020 rulemaking, is unambiguous:
Enterprise value = equity market value + indebtedness + minority interests + preferred stock − cash and cash equivalents
Each term earns its place. Equity market value is what the shares cost. Indebtedness is added because a buyer inherits the borrowings: acquiring a company means acquiring its obligations, and those must be serviced or repaid out of the same cash flows the buyer is paying for.
Minority interests and preferred stock are other people’s claims on the same assets.
Cash is subtracted because it comes back to the buyer on day one, reducing the true cost.
The intuition is straightforward. Think of a house with a mortgage. The asking price is the equity. The buyer also takes on the outstanding loan, and finds cash left in a drawer on completion. What the house actually cost is the price, plus the loan, less the cash.
Every component answers one question: what does the buyer actually end up owning, and owing.
Microsoft Paid $75.4 Billion for a $68.7 Billion Company
What the headline had already netted off
Microsoft’s own announcement on January 18, 2022 is explicit. The deal was priced at $95.00 per share and described as “valued at $68.7 billion, inclusive of Activision Blizzard’s net cash”. Everything turns on that phrase. The reported figure was never the cheque. It was an enterprise value, already reduced by the cash Activision held.
Activision’s last balance sheet before the merger vote, at December 31, 2021, showed $10,423 million of cash and cash equivalents against $3,608 million of long-term debt, net. That is a net cash position of roughly $6.8 billion, and it is almost exactly the gap that appeared later.
What the closing accounts showed
The transaction completed on October 13, 2023. Microsoft’s subsequent annual report records a total purchase price of $75,408 million, and its purchase price allocation quantifies both adjustments in a single table: $12,976 million of cash and equivalents came straight back to Microsoft as an acquired asset, and $2,799 million of Activision long-term debt was assumed.
A reader who took $68.7 billion as the price would have understated the cash outlay by nearly 10%. A reader who took $75.4 billion as the cost of the business would have ignored the $13 billion that came back. Both figures are correct; they answer different questions.
When a deal headline says a company was acquired “for” an amount, check whether the number is an equity price or an enterprise value. Press releases frequently quote enterprise value because it is the larger figure for an indebted target and the smaller one for a cash-rich target. Both make a useful headline, for opposite reasons.
Rebuilding the Number From Filings
Every input is public. Activision’s annual report discloses 779,234,888 shares outstanding at February 18, 2022, and states that stock held by non-affiliates was worth $73,721,746,854 at June 30, 2021. Multiply a share count by a price and you have the equity leg; the balance sheet supplies debt and cash for the rest.
Allen & Company, financial adviser to Activision, did precisely this in its fairness analysis. Its work in the merger proxy builds enterprise values from unaffected closing stock prices on January 14, 2022, plus total debt, less cash.
The method a bulge-bracket bank applies to a $69 billion transaction is the method above, run on numbers anyone can pull from EDGAR.
Matching the numerator to the denominator
One rule governs every use of the measure, and the SEC record states it plainly: if the denominator is an enterprise value, the numerator must be the purchase price plus debt assumed, net of cash. An equity price divided by an enterprise value is not a ratio of anything.
This is the most common error in casual valuation work. Dividing market capitalization by EBITDA, or enterprise value by net income, produces a number that looks like a multiple and means nothing, because the two halves describe different claims on the business.
The Opposite Shape: When Debt Dwarfs Equity
Activision was a cash-rich company whose enterprise value fell below its equity value. Charter Communications is the mirror image, and it shows why market capitalization alone can be close to useless.
At December 31, 2025 Charter disclosed approximately $94.6 billion of debt principal and a leverage ratio of 4.15 times adjusted EBITDA, against just $477 million of cash. Its Class A stock held by non-affiliates was worth roughly $37.1 billion at June 30, 2025.
Roughly seven of every ten dollars of claim on this business belong to lenders, not shareholders. Any comparison of Charter against a debt-free competitor on market capitalization alone would misstate its size by a factor of more than three. This is the situation enterprise value was built for.
Charter’s agreement with Cox, reached May 16, 2025, puts every component in one transaction: $3.5 billion of cash for the equity sale, plus $500 million of cash, $6.0 billion of convertible preferred units and about 33.6 million common units. Preferred stock and minority interests are not textbook abstractions in a deal of that shape. They are line items in the price.
EV/EBITDA, and the Spread That Undermines It
Enterprise value is most often used as the numerator of EV/EBITDA, which pairs the full cost of the business against pre-financing earnings. Because both halves sit above the capital structure, the ratio compares companies with different debt loads on something closer to equal terms than the P/E ratio allows.
The multiples themselves are wider than the confidence usually placed in them. In the Activision proxy, Allen & Company’s trading comparison across Take-Two, Electronic Arts and Ubisoft produced enterprise value to estimated EBITDA of 8.4x to 19.1x for calendar 2022, and 7.3x to 15.6x for 2023. Three companies in one industry, on one day, more than doubling across the range.
The precedent-transaction analysis is wider still: across eleven interactive-entertainment acquisitions, EV to last-twelve-months EBITDA ran from 5.6x to 29.9x. Anyone quoting a “typical” multiple for a sector is compressing a fivefold spread into a single number.
EBITDA is not a free parameter. The SEC staff’s non-GAAP guidance holds that EBITDA means net income before interest, taxes, depreciation and amortisation, and a figure computed differently must not be called EBITDA. When a company presents “adjusted EBITDA”, read what was adjusted before comparing its multiple to anyone else’s.
Why the SEC Refused to Define It
In 2020 the Commission amended its tests for whether an acquisition is significant enough to require separate financial statements. Commenters asked it to use enterprise value as the denominator of the Investment Test. It declined, and the reason is instructive: the term has no agreed-upon definition.
That is a regulator, choosing a measure for a binding rule, concluding that enterprise value is too loosely specified to carry legal weight. The formula above is the common construction, not the only one. Practitioners differ on whether to include operating leases, pension deficits, short-term investments alongside cash, or restricted cash at all.
So two analysts can compute different enterprise values for the same company on the same day and both be defensible. The remedy is not to distrust the measure but to state the construction and apply it identically across every company being compared.
The Cases That Defeat It
- Not all cash is available. Subtracting the full balance assumes every dollar could be paid out on completion. Cash held for regulatory capital, trapped in foreign subsidiaries, or committed to operations is not free, and netting it off overstates the discount.
- Financial companies break the logic. For banks and insurers, debt is raw material rather than financing. Adding it to equity produces a figure with no economic meaning, so these are valued on book value and return on equity instead.
- The equity leg moves constantly. Market capitalization changes every second, so enterprise value inherits that volatility even when the balance sheet is unchanged.
- Balance-sheet data is stale. Debt and cash come from a quarter-end that may be eleven weeks old, against a share price from this morning.
- Off-balance-sheet obligations sit outside it. Underfunded pensions, litigation exposure and certain lease commitments are real claims that the standard formula does not capture.
The Bottom Line
Enterprise value answers the question market capitalization cannot: what would it cost to own this business outright, debt and all, net of the cash that comes with it. For a leveraged company like Charter, where lenders hold roughly 72% of the total claim, no other measure describes the scale of what is being valued.
Treat it as a construction rather than a fact. The SEC declined to define it because there is no single right version, so state which components you included, apply that same definition to every company in the comparison, and match your numerator to your denominator. Microsoft’s $68.7 billion and $75.4 billion were both accurate descriptions of the same deal, and confusing them would have misread the price by the better part of $7 billion.
For the equity half of the calculation, see market capitalization; for the cash that gets netted off, see free cash flow.
