Net Debt and Cash-Free, Debt-Free: The UK Equity Bridge

Where a UK SME sale is quietly won or lost

Sellers spend months negotiating the EBITDA multiple. Buyers spend weeks negotiating the definition of net debt. Both are right about where their leverage sits, and the seller almost always underestimates how much of the headline price is decided in the equity bridge that sits underneath a "cash-free, debt-free" offer.

A £6m headline can become £5.2m by the time completion accounts are agreed - not because the buyer changed their mind, but because a handful of items moved from "cash" to "debt-like" between heads of terms and signing. This guide covers what the mechanism actually is, how each line item is negotiated, and where an independent valuation protects the seller before any of it is signed.

What "cash-free, debt-free" really means

Almost every UK SME deal is priced on a cash-free, debt-free (CFDF) basis. The buyer offers an enterprise value for the trading business, then adjusts to equity value - the actual cash paid to shareholders - using a defined equity bridge:

Equity Value = Enterprise Value - Net Debt +/- Working Capital Adjustment - Debt-like Items + Surplus Assets

CFDF is not a promise to leave the cash in the business. It is a pricing convention: the buyer assumes the seller extracts surplus cash and repays all borrowings at completion, and pays a headline that reflects a "normal" balance sheet. The fight, in practice, is what counts as debt, what counts as cash, and what "normal" working capital looks like.

Net debt: the four buckets

Net debt is not simply "loans minus cash". A mature buyer definition covers four buckets, and each is a negotiation:

The single-largest mistake sellers make is agreeing to a broad "debt-like items" clause in heads of terms without a defined list. By the time the SPA is drafted, every unfavourable line the buyer's due-diligence team can find is inside that clause.

The items that reliably become "debt-like"

Buyers routinely try to push the following into the net debt calculation. Sellers who have seen the list in advance can pre-empt the argument:

• Dilapidations provisions on leased premises where the lease has more than three years to run.
• Deferred revenue on annual contracts already paid in advance, on the argument that the buyer must deliver the service without receiving the cash.
• Customer deposits and retentions held on the balance sheet.
• Corporation tax accrued but not paid, on the theory that a "normal" balance sheet would have paid it.
• Bonuses, holiday pay accruals and deferred employer NICs on staff at completion.
• Overdue trade creditors stretched beyond normal terms.
• Capex commitments contracted but not yet incurred.
• Warranty and product liability provisions on historical sales.

Some of these are legitimate, some are not. A rigorous seller-side view is that any item is only "debt-like" if a normal, well-run business of the same type would not carry it. A dilapidations provision on a 15-year lease is genuinely debt-like; a two-week holiday pay accrual for the office staff is not.

Working capital peg: the silent value transfer

The working capital adjustment is where more UK SME value is lost, per hour of negotiation, than anywhere else in the equity bridge. The mechanism is symmetrical in theory. In practice, sellers underestimate seasonality and hand over cash without realising it.

The peg is the "normal" level of trade working capital the buyer expects to inherit. Deliver more than the peg at completion and the seller is paid the surplus. Deliver less and the seller writes a cheque back to the buyer.

Two things reliably go wrong:

1. The peg is set on a 12-month average but completion is scheduled at the trough of the working capital cycle. The buyer inherits a fully-stocked balance sheet with no accrued creditors; the seller pays the difference.

2. The peg is defined on a normalised basis but the "normal" excludes months when the business genuinely needed higher inventory or debtor days. The seller loses that working capital permanently.

A well-prepared seller runs the working capital calculation on 24-36 months of monthly data before signing heads of terms, agrees the seasonality curve with the buyer, and defines both the peg and the completion mechanic - target date, measurement basis, dispute resolution - in the SPA.

A worked equity bridge

The mechanism is easier to see with a concrete example. A profitable UK B2B services business, agreed enterprise value of £6.0m:

Everything in the table was negotiable at the heads-of-terms stage. Once inside a signed SPA framework, each line is defended by the buyer's advisors with the SPA text in one hand. The time to negotiate is before signing.

Deferred consideration, escrow and holdbacks

The bridge above assumes cash on completion. In reality, UK SME buyers routinely hold back 10-20% of the equity value in:

• Escrow - security for warranty claims, typically released in tranches over 12-24 months.
• Retention - security for a specific known risk (a disputed customer, a pending HMRC enquiry, a lease assignment).
• Deferred consideration - fixed instalments payable over 1-3 years, usually unsecured.
• Earn-out - variable consideration tied to post-completion performance.

None of these change the headline enterprise value, but each changes the risk profile of what the seller actually receives. A "£6m deal" with £1.5m tied up in a two-year earn-out and £600k in escrow is a very different economic outcome from a £6m all-cash deal.

Why the equity bridge is the seller's second valuation

An independent pre-sale valuation gives the seller a defensible enterprise value. It also, if built properly, gives the seller a normalised balance sheet view: what a fair net debt looks like, what a defensible working capital peg is, and which balance sheet items a buyer will legitimately push into debt-like status.

Sellers who commission that work early walk into heads-of-terms with:

• A list of items they will accept as debt-like, and a list they will not.
• A working capital peg they have already stress-tested against 24-36 months of monthly data.
• A view on which cash and near-cash items they intend to strip before completion.
• A model of the equity bridge under three completion-date scenarios.

That preparation is what turns a CFDF offer from a moving target into a defensible number. Sellers who arrive without it discover, weeks after completion, that a meaningful slice of their sale proceeds was left on the negotiating table.

What to do before you accept the headline

The headline number is easy to celebrate. The equity bridge is where the money actually moves. Before signing heads of terms:

• Run a monthly working capital analysis over the last 24-36 months. Identify the trough, the peak and the seasonal average.
• List every balance sheet item the buyer could plausibly call debt-like. Decide in advance which you will concede and which you will not.
• Extract surplus cash on a defined mechanism - not ad-hoc withdrawals that a buyer will later reverse.
• Agree the completion date with the working capital cycle in mind. A three-month shift in completion can be worth six-figure sums.
• Get an independent valuation that covers the equity bridge, not just the enterprise value. It is the cheapest insurance a seller buys in the entire process.

The value protected by that work is routinely a multiple of the fee. The value lost without it is often invisible until it is too late to recover.
