Business Valuation Methods: How UK Companies Are Valued in M&A

Valuation is both an art and a science. In UK M&A transactions, several methods are used — often in combination — to arrive at a fair price. Understanding them helps founders set realistic expectations, identify the right time to sell, and negotiate effectively.

Why Valuation Method Matters

The same business can produce very different headline numbers depending on which method a buyer uses. A high-growth SaaS company might be worth 8× ARR on a revenue multiple basis but only 5× EBITDA on an earnings basis — a difference that could be worth tens of millions of pounds.

Knowing which method applies to your business is the first step to understanding what you’re worth.

1. Revenue Multiples

Revenue-based valuation is most common for high-growth companies — particularly in technology and SaaS — where EBITDA may be low or negative because profits are being reinvested into growth.

The buyer applies a multiple to annual recurring revenue (ARR) or total revenue.

What drives a higher revenue multiple:

• Net Revenue Retention (NRR) above 110%
• Revenue growth above 40% YoY
• Gross margins above 70%
• High switching costs / strong lock-in
• Large, underpenetrated total addressable market (TAM)

2. EBITDA Multiples

For profitable, established businesses, EBITDA multiples are the standard valuation method. This approach is favoured in leveraged buyouts because lenders assess debt serviceability relative to earnings.

EBITDA = Earnings Before Interest, Tax, Depreciation, and Amortisation.

Key drivers of multiple expansion:

• Sector — Technology and healthcare attract higher multiples than manufacturing or retail
• Recurring revenue — Subscription or contract-based revenues command a premium over transactional revenue
• Management depth — A business that isn’t dependent on the founder commands a higher multiple
• Growth rate — Growing EBITDA attracts better pricing than stable or declining earnings
• Margins — High-margin businesses are worth more per pound of earnings

3. Discounted Cash Flow (DCF)

DCF analysis projects the company’s future free cash flows and discounts them back to present value using a risk-adjusted discount rate (WACC).

The formula in simple terms:

Value = Sum of (Future Cash Flows ÷ (1 + Discount Rate)^Year) + Terminal Value

DCF is theoretically rigorous but highly sensitive to assumptions:

Assumption	Impact
Revenue growth rate	The biggest single driver of value
EBITDA margin expansion	Second most important — small changes compound significantly
Discount rate (WACC)	A 1% change in WACC can move value by 10–15%
Terminal growth rate	Typically set at 2–3% (long-run inflation)

In practice, DCF is most commonly used as a cross-check alongside multiple-based valuations, rather than as the primary method. It’s more prevalent in large-cap and infrastructure transactions.

4. Asset-Based Valuation

For asset-heavy businesses — property companies, manufacturers, or distressed situations — the value of underlying tangible assets may drive transaction pricing.

This method is common for:

• Property-backed businesses (hotels, care homes, student accommodation)
• Businesses in administration where goodwill has been impaired
• Asset-heavy manufacturers where plant and equipment holds significant value

It is rarely the primary method for service or technology businesses.

5. Adjusted and Earn-Out Structures

Real-world deal prices often differ from headline multiples due to:

• Normalised EBITDA — Buyers adjust for one-off costs (restructuring, owner salary, exceptional items) to arrive at a “maintainable” earnings figure
• Earn-outs — A portion of the price is contingent on hitting post-completion targets. Common when buyer and seller disagree on growth prospects
• Working capital adjustments — Final price is adjusted up or down based on the actual cash, debt, and working capital at completion (“locked box” vs “completion accounts” mechanisms)
• Seller financing — Part of the consideration is deferred or structured as a vendor loan

Benchmarking Your Valuation

The most effective way to understand what your business is worth is to study comparable transactions. Use the PE Deals database to filter by sector, deal type, and value range to find relevant benchmarks for your specific business.

Understanding the range of outcomes — and the variables that explain the difference between the low and high end — is the foundation of any effective exit negotiation.
