Company Valuation Basics

Valuation is the process of deciding what a company is worth in dollars. It sounds straightforward — a company is worth whatever someone will pay for it — but behind that simple idea sits a mess of assumptions, estimates, and judgment calls. In M&A deals, valuation is the battleground where buyers and sellers negotiate. In fundraising, it’s what determines how much equity the investor gets for their cheque. Understanding valuation doesn’t mean you need to build models; it means you can spot when a number is grounded in logic or pulled from the air.

Why valuation matters

Before a deal closes, buyer and seller have to agree on a price. They can’t just shake hands on “fair value” — the contract needs a number. The buyer wants to pay as little as possible; the seller wants to get paid as much as possible. Valuation is the framework they use to argue for their side. A well-reasoned valuation strengthens your negotiating position. A sloppy one gets picked apart in due diligence.

Valuation also matters in fundraising. When a startup raises money from venture capitalists, they negotiate a post-money valuation — what they claim the company is worth after the investor’s money arrives. A $10M investment at a $100M post-money valuation means the investor owns 10% of the company. The higher the valuation, the less equity you give up.

Common valuation methods — in plain English

Multiples: a shortcut based on market comparables

The simplest and fastest valuation method is multiples. You find comparable companies (usually public ones, because their financials are public) and apply a multiple to the company you’re valuing.

Price-to-Earnings (P/E) multiple is the most famous. If Apple trades at a P/E of 30, that means investors pay $30 for every $1 of annual earnings. If your private company earns $10M a year, applying Apple’s P/E would value your company at $300M. The logic: if you’re similar to Apple, investors should pay a similar price per dollar of profit. The catch: you’re almost never similar to Apple. A tech startup growing 50% a year has a different risk profile than a mature software company growing 5%. So picking the right comparable is crucial.

EV/EBITDA is another classic multiple. EV is enterprise value (more on that in a moment). EBITDA is earnings before interest, taxes, depreciation, and amortization — basically, operating profit without the accounting noise. If the median SaaS company trades at 8x EV/EBITDA and your company has $5M of EBITDA, you’d be valued at $40M. The advantage of EV/EBITDA is that it’s cleaner for comparing companies with different capital structures or tax rates.

The real skill is not in the math — it’s in picking the right comps and the right multiple. A buyer will cherry-pick comps that justify a low number; a seller will do the same to justify a high one. The deal ends up somewhere in the middle.

Discounted Cash Flow (DCF) — the theoretically pure method

Discounted Cash Flow is the idea that a company is worth the sum of all its future cash flows, adjusted for time and risk. The logic is almost tautological: if you’re going to own a company, you’ll receive cash from it. Add up all that cash and you have what you should be willing to pay.

In practice, this requires you to forecast the company’s cash flow for five, ten, or even thirty years into the future. Then you discount each year’s cash by a percentage that accounts for risk and the time value of money. A cash flow you’ll receive in five years is worth less than cash you get today, because you could invest today’s cash and earn a return. A risky company’s cash is discounted more than a stable company’s.

DCF is theoretically sound but practically fragile. Small changes to your growth assumptions or discount rate can swing the valuation by tens of millions. A 5% higher growth rate or a 1% lower discount rate can nearly double the number. That’s why DCF is often used to check whether a multiple-based valuation is in the ballpark, not as the primary method.

Comparable company analysis

You pull financial data from similar companies (usually public ones) and see what multiples they trade at. If five software companies have a median revenue multiple of 5x (meaning investors pay $5 for every $1 of revenue), and your company has $20M in revenue, the valuation would be $100M. This is similar to the multiples approach but more rigorous because you’re using a basket of comparables, not just one.

Rule of thumb: a strong valuation is grounded in comparable companies and sense-checks against cash flows. If a company is valued at 20x revenue and growing 10%, something is off. If it’s growing 100% with a billion-dollar TAM, maybe not.

Enterprise value vs. equity value

This is where many people get tangled up, so let’s be precise.

Enterprise Value (EV) is what the entire business is worth, including both the equity holders and the debt holders. If a company is worth $100M and has $20M of debt, the enterprise value is $100M. The equity holders own the other $80M.

Equity Value is what the shareholders own — just the slice left after you subtract debt, preferred shares, and other liabilities. In the example above, equity value is $80M.

Why the distinction? Because when you acquire a company, you’re buying the whole enterprise — you inherit both the assets and the debt. The purchase price you negotiate is typically the enterprise value. The equity value is what the shareholders actually walk away with (the purchase price minus the debt the company owed).

If you’re pitching an M&A deal to your board, always be clear: “We’re paying $100M enterprise value, but their debt is $20M, so the equity holders get $80M.” The difference matters for the return calculation.

Why two buyers value the same company differently

This is the most important insight: the same company can be worth different amounts to different buyers.

Company X has $10M in annual revenue and $2M in annual profit.

Buyer A is a large software company that could fold Company X’s product into its platform and eliminate redundancy, cutting costs by $500k a year. The extra cash is worth money, so Buyer A values Company X higher than the standalone number would suggest.

Buyer B is a financial buyer (a private equity firm) with no operational synergies. It values Company X based on its standalone cash flows, applying a standard multiple.

Buyer A pays more than Buyer B for the exact same company because A can extract value that B cannot. That value is called synergy, and it’s baked into the buyer’s willingness to pay. If you’re selling, you want bidders with synergies. If you’re buying, you need to make sure those synergies are real and achievable.

A buyer’s valuation also depends on its cost of capital. A buyer with cheap access to debt can justify a higher price because the debt is cheaper than you paying for the same acquisition with equity or cash.

How to use it

When a deal valuation comes up, ask which method was used. If it’s multiples, ask what comparables were chosen — cherry-picked comps are a red flag. If it’s DCF, ask what growth and discount-rate assumptions were made; small changes to those assumptions shift the number wildly. Compare enterprise value to equity value to understand what the shareholders actually take home after debt. Most importantly, ask whether there are synergies baked in. If the buyer is paying a premium, where is that premium coming from? Can you measure it? Has anyone stress-tested it? Useful phrases: “Which method was used?” “What comparables are most relevant?” “What’s embedded in that price as synergy?” “Are those synergies actually achievable?”
