How M&A deals actually work
7 min read · updated July 2, 2026
Most beginners picture a deal as two CEOs shaking hands over a number. That's not how it works. A sale is a process, run by bankers, designed to create competition and push the price up. If you understand the stages, you understand the job.
Let's start with the only question that matters to a buyer.
Why buy at all?
Nobody pays a premium for a company out of politeness. A buyer pays up because owning the target is worth more to them than the standalone price. The reasons cluster into a few buckets:
- Synergies. Cost synergies (cut duplicate overhead, close redundant plants, combine back offices) or revenue synergies (cross-sell to each other's customers). Cost cuts are believable. Revenue synergies are where hope goes to die, so smart buyers haircut them hard.
- Market share and scale. Buy the #3 player, become the clear #1, gain pricing power.
- Vertical integration. Buy your supplier or your distributor to control the chain and margin.
- Diversification. Add a business with a different cycle so the whole company is steadier.
- Defensive or tax-driven. Buy a threat before a rival does, or acquire to use a target's tax attributes.
A buyer's ceiling is the standalone value plus what the combination uniquely adds. Two buyers looking at the same target can rationally arrive at very different maximum prices, because they bring different synergies to the table. That gap is the whole game.
The sell-side process, stage by stage
When a company hires a bank to sell it, the bank runs a script. The point of the script is leverage over price: keep multiple buyers in the room, control information, and never let one party think they're the only bidder.
Here's the sequence.
| Stage | What happens | Why it exists | |---|---|---| | Teaser | A one-page, no-name summary goes to potential buyers | Gauge interest without revealing who's for sale | | NDA | Interested parties sign confidentiality | Gate the real information | | CIM | The confidential information memorandum, a 50+ page book on the business | Give bidders enough to value it | | First-round bids | Non-binding indications of interest (price ranges) | Cut the field to serious buyers | | Management presentations | Finalists meet the leadership team, get a data room | Let real buyers diligence deeply | | Second-round bids | Binding offers with a marked-up contract | Force commitment on price and terms | | Exclusivity | The seller picks one, others go home | Trade competitive tension for a signed deal | | Signing and close | Definitive agreement, then regulatory approval and funding | Money moves, ownership transfers |
The sell-side banker's job is to run this so the seller gets the highest credible price. The buy-side banker's job is the mirror image: help a buyer win without overpaying.
Broad auction vs. targeted process
Not every sale goes to fifty buyers. There are two shapes:
- Broad auction. Contact a wide list, maximize competition, accept that word gets out. Best when the seller wants top dollar and doesn't fear leaks.
- Targeted process. Approach a short list of likely buyers, sometimes just one. Best when confidentiality matters (employees, customers, competitors) or when only a handful of buyers could realistically own the asset.
More bidders usually means a higher price. But a leaky auction can spook customers and staff, so sellers trade breadth against discretion.
Strategics vs. financial buyers: who pays more?
Two very different animals show up to buy companies.
A strategic buyer is an operating company in the same or an adjacent industry. A financial buyer is a private equity sponsor that buys with an LBO, loads on debt, improves the business, and sells in five years.
Here's the key difference in one line: the strategic can fold the target into an existing business and realize synergies. The sponsor, buying a standalone company, generally cannot.
Play it out with round numbers. Say a target does $100 of EBITDA and the market pays about 8x.
A financial buyer values it on those standalone cash flows and their return math. They might stretch, but their ceiling is anchored near that $800.
Now the strategic. Suppose the combination produces $20 of cost synergies. To that buyer, the target is really worth:
The strategic can pay up toward $960 and still come out even on the multiple, while the sponsor is capped near $800. Same asset, very different ceilings.
Two errors that make you sound green.
First, not knowing why a strategic usually pays more. It's the synergies. A strategic buys $120 of combined EBITDA where you only see $100; a financial buyer buys the $100 as-is and has to hand a chunk of the upside to lenders and its own return target. If you can't say the word "synergies" when asked who pays more, you've failed the question.
Second, treating M&A as a single price negotiation. It's a staged auction. The teaser, the CIM, the two rounds of bids, exclusivity, all of it exists to manufacture competition and control information. Say "the buyer and seller agree on a price" and you've skipped the entire process the job is built around.
When does the financial buyer win anyway? When it can pay a lower control premium and still hit its return because the target is underpriced, cash-generative, and lightly levered. And plenty of sponsors now own platform companies, so they can bolt the target onto an existing portfolio company and get strategic-style synergies too. The clean line still holds for the interview: all else equal, the strategic's synergies give it the higher ceiling.
Two related but different concepts here. Standalone value comes from a company's own cash flows. The control premium is the extra a buyer pays over the current trading price to own the whole thing and run it, and part of what justifies that premium is synergies. See enterprise value vs. equity value for the value the premium sits on top of, and accretion / dilution for whether the deal helps EPS once it closes.
Why deals still fail
Buyers overpay. Synergies show up late or never. Cultures clash. Regulators block it. The base rate on value-destroying acquisitions is ugly, and the usual culprit is a buyer who talked itself into revenue synergies to justify a price it wanted to pay anyway. Discipline on price is the whole ballgame, which is exactly why the sell-side runs a process designed to erode it.
Practice walking the seven stages out loud, in order, in under thirty seconds: teaser, NDA, CIM, first-round bids, management presentations, second-round bids, exclusivity and close. Then be ready to layer on the "who pays more" logic without a beat of hesitation. Anyone can memorize a list. The candidate who can say why each stage exists (competition, information control, commitment) and connect it to why a strategic outbids a sponsor is the one who reads as someone who has actually sat on a deal. That fluency is the depth that separates you in a Superday.
Glossary
New to the lingo? Every term used above, in plain English.
- Synergies
- The extra value two companies expect to create by combining, usually cost savings or added revenue that neither could achieve alone.
- Strategic buyer
- A company that buys another company in its own or an adjacent industry, often to capture synergies. It can usually pay more than a financial buyer because of those synergies.
- Financial buyer
- An investor, usually a private equity firm, that buys a company to improve it and sell it later for a profit. Its price is set by the returns it needs, not by synergies.
- Sell-side
- The investment banks that advise companies and sell securities to investors. Named because they help clients sell deals. The opposite of the buy-side.
- Buy-side
- The investors who buy securities, such as private equity firms, hedge funds, and asset managers. In a sale process it is the party trying to buy the company.
- LBO (Leveraged Buyout)
- Buying a company using mostly borrowed money, then using the company’s own cash flow to pay that debt down over time. The classic private equity playbook.
- Sponsor
- A private equity firm. In an LBO the sponsor is the buyer that puts up the equity and controls the company.
- EBITDA
- Earnings Before Interest, Taxes, Depreciation, and Amortization. A rough proxy for a company’s operating cash profit, before financing and accounting choices.
