How to Write an Acquisition Thesis

Short answer: An acquisition thesis is one page that says what you will buy, why, how you will pay for it, and how you will know it worked. It has five parts: the constraint the deal solves, the asset you are buying, the target profile, the funding plan, and the one number that must move, with your walk-away conditions written down before you look at a single company. Its main job is not to find the deal. It is to tell you, quickly, which deals to ignore.

Why bother writing it down

Owners who decide to buy usually start by looking at companies. That is backwards. Without a written thesis, every company looks interesting for a week, each one gets judged by a different yardstick, and the deal that finally gets done is the one with the best story, not the best fit.

A written thesis does three jobs:

• It filters. Most of the companies you will hear about are wrong for you. A thesis lets you say no in minutes instead of weeks.
• It travels. A broker, a lender, or a CPA can read one page and tell you whether they know a fit. A vague "we're looking to grow" gets you nothing.
• It keeps you honest. When you are three months into a deal and emotionally committed, the thesis is the document that reminds you why you started and what would make you stop.

Part 1: The constraint

Start with the problem, not the target. What is holding your business back that an acquisition fixes faster than building would? The honest answer is usually one of a short list: you cannot hire technicians fast enough, one customer is too much of your revenue, your revenue restarts every January, your market is saturated, or a supplier controls your costs.

If you cannot name the constraint, you are not ready to buy. If buying does not fix it faster than hiring or marketing would, you should not buy. See organic vs acquisition growth.

Part 2: The asset you are buying

Every acquisition is really buying one thing the financial statements understate: density, customers, revenue quality, people, supply, or a new market. Name it, because it decides what the business is worth to you, what you check in diligence, and what kills the deal. A company bought for its technicians and a company bought for its maintenance agreements are different deals even with identical numbers.

The constraint usually names the asset. The menu, with the trap in each one, is the eight inorganic moves in the trades.

Part 3: The target screen

The screen is the filter every company runs through. Write it in plain terms a broker can match against:

• Trade and service mix. Which trade, and what share service versus project work.
• Size. A revenue or earnings range. Too small and it will not move your numbers. Too big and you cannot fund or absorb it.
• Geography. A drive time from your shop, not a state. Density deals die at the edge of your routes.
• Owner situation. Retiring with no successor, a partner buyout, burned out, or wanting to stay on in a role. Each one changes how the deal is built.
• Integration risk. How different their software, pay plans, and way of working are from yours.

Part 4: The funding plan

Know roughly how you would pay before you fall in love with a company: senior debt or SBA, a seller note, your own cash, and how much debt your combined cash flow can carry. A target that only works if everything goes right on financing does not fit the thesis. See the acquisition capital stack and, if you already own a company, how the 2026 SBA rules favor established owners.

Part 5: The one number, and the walk-away conditions

Pick the single measure that proves the deal worked: jobs per truck per day, maintenance agreements as a share of revenue, the largest customer's share, technician headcount. If the deal does not move that number, it did not work, whatever else happened.

Then write the walk-away conditions, the facts that end a deal no matter how much you like it. Write them now, while you are calm. Examples:

• The license sits with one person who will not stay through the transition.
• One customer is more than a third of revenue.
• The combined business cannot cover its debt payments with room to spare.
• The owner wants to keep running it.
• The earnings do not hold up once the add-backs are tested.

The ones most deals actually die on are ranked in what kills small-business acquisitions.

The template

Most of a thesis fits in one sentence:

Add the target screen and the walk-away conditions underneath it and you have a working thesis on one page.

A worked example

An illustration, not a client: a residential HVAC company doing $9 million in revenue, mostly replacement installs, with a maintenance agreement base that has been flat for three years.

• Constraint: revenue restarts every season and the install crews sit idle in shoulder months.
• Asset: revenue quality, through a mix shift.
• Target screen: a service-heavy HVAC or plumbing company, $2 to $5 million in revenue, within 45 minutes of the shop, at least 1,500 active maintenance agreements, owner retiring with no family successor.
• Funding: SBA 7(a) senior debt with a seller note, sized so the combined company covers debt payments at least 1.25 times.
• The one number: maintenance agreements as a share of revenue, from 12 percent to 25 percent within two years.
• Walk away if: the agreements turn out to be unrenewed or underpriced, the service manager will not stay, or the owner is the only person customers call.

Everything that does not fit that screen gets a fast, polite no. That is the point.

Test it before you use it

Run the page past three readers:

• A lender: would they finance a deal that fits this screen?
• A broker in your trade: can they name a company that fits after one read? If not, the screen is too vague or too narrow.
• Your own leadership: can the business absorb this deal without breaking what already works?

Rewrite the thesis when the constraint changes, usually after each deal closes. The first acquisition often changes what the second one should be.
