A real-world case study showing how a Spanish buyer structured a 2.1M euro business acquisition using bank debt, vendor financing, and public guarantees — with 18-month results included.
Acquisition financing: bridging the gap between price and available capital
For most buyers, business acquisition financing is the single biggest practical challenge in any M&A deal. You have found the right company, completed your due diligence, and agreed on a fair price — but that price is larger than the cash you have available. What are your options?
This article skips the theory. Instead, it walks you through a real-world case study from Spain showing exactly how a buyer structured the financing for a 2.1 million euro acquisition using five different instruments — and what actually happened eighteen months after closing.
The 5 acquisition financing tools every buyer should understand
Before diving into the case study, here is a clear overview of the instruments typically available when financing a business acquisition:
1. Senior bank debt
The backbone of most acquisitions. Banks lend against the target company's assets and cash flows, typically up to 3–4 times EBITDA, with 5–7 year repayment schedules and floating interest rates (e.g. Euribor + 2–3.5%). The lender's central question: can the acquired business generate enough cash flow to service the debt comfortably?
2. Mezzanine or subordinated debt
When senior debt does not close the equity gap, mezzanine steps in as a second layer. It sits behind senior debt in the repayment waterfall, takes more risk, and charges more for it — typically 8–14% annually. In return, mezzanine structures often defer cash interest using PIK (payment-in-kind) mechanics, which protect near-term liquidity.
3. Seller financing (vendor loan)
The seller defers receipt of part of the purchase price, effectively lending it to the buyer. The buyer pays 70–80% at closing and the remainder over 2–4 years. Beyond reducing external financing needs, seller financing aligns the seller's interests with a smooth handover — particularly valuable when client relationships are central to the business's value.
4. Co-investors and private capital
For larger transactions, or when the buyer wants to limit personal financial exposure, a co-investor can bring additional equity. This might be a private equity fund, a family office, or an industrial partner. The lead buyer retains operational control; the co-investor receives a minority stake in exchange for capital and expects financial returns.
5. Public financing instruments
In Spain — and similar instruments exist across Europe — publicly backed bodies such as ICO, ENISA, and regional guarantee societies (SGR) provide complementary financing lines or guarantees that improve the buyer's credit profile. These instruments rarely cover an entire deal on their own, but can be the bridge that makes a structure viable.
Case study: acquiring an industrial maintenance company in Spain
The names in this case study are fictional, but the structure and numbers are representative of real SME M&A transactions in Spain.
The setup
The buyer: Carlos, 47, managing director of an industrial logistics company in Valencia generating 4 million euros in revenue and 600,000 euros in EBITDA. He has been pursuing inorganic growth for years and has finally found the right target.
The target: An industrial maintenance company in Castellón with 3.2 million euros in revenue and 480,000 euros in normalised EBITDA. The owner — 66 years old — wants a clean exit, with no family successors willing to take over the business.
Agreed price: 2.1 million euros (4.4x EBITDA — a reasonable multiple for the industrial services sector).
Carlos's available equity: 400,000 euros — 19% of the price. He needs to finance the remaining 1.7 million euros.
The financing structure
Working with his financial adviser, Carlos builds the following structure:
- Own equity: 400,000 € (19%) — Carlos's direct contribution, demonstrating commitment to lenders.
- Senior bank debt: 960,000 € (46%) — Six-year loan at Euribor + 2.8%, secured against the target's shares and a partial personal guarantee from Carlos.
- Vendor loan: 420,000 € (20%) — The seller defers 420,000 euros over three years at 4% per annum. Additional condition: the seller stays on as an adviser for 12 months to ensure continuity with key clients.
- SGR guarantee + ICO tranche: 320,000 € (15%) — A regional guarantee society provides an SGR guarantee that improves bank terms, complemented by an ICO tranche at advantageous conditions.
Total annual debt service in years one to three: approximately 320,000 euros. Combined EBITDA of both businesses estimated post-integration: 950,000 euros. Debt service coverage ratio (DSCR): above 2.5x — comfortable, but not excessive.
Results at 18 months
- Integration took longer than expected: teams needed eight months to work smoothly together, versus the four months initially assumed.
- Year-one combined EBITDA came in at 870,000 euros (91% of forecast) — enough to service all debt with margin.
- The vendor loan proved strategically crucial: the seller's 12-month advisory role was key to retaining three clients that represented 40% of revenue.
- Carlos's main lesson: he would have preserved more personal liquidity by using a mezzanine tranche rather than deploying all his equity reserves.
The most common mistakes in acquisition financing
- Forgetting working capital. Acquisitions typically require injecting additional working capital in the first months. Buyers who do not budget for this can face a cash crisis at the worst possible moment.
- Overleveraging. Debt above 4–5x EBITDA leaves little room for underperformance. Banks attach covenants to acquisition loans; breach them, and you may face accelerated repayment.
- Poorly structured vendor loans. Some sellers accept deferred payment but demand punitive terms — high rates, short tenors, personal guarantees. Vendor financing should be negotiated as an integral component of the total price, not an afterthought.
- Underestimating the true cost of mezzanine. A nominal 10% rate can exceed 18% in effective cost once fees, PIK, and warrants are included. Model the full effective cost before committing.
- Having no plan B. If the bank says no, the seller will not defer, or due diligence reveals a hidden liability, buyers without alternatives end up signing on bad terms or walking away from otherwise viable deals.
Choosing the right financing structure for your acquisition
There is no universal formula. The optimal structure depends on:
- Deal size: below 1 million euros, bank debt and seller financing usually suffice. Above 5 million, mezzanine and private co-investors become more relevant.
- Buyer's credit profile: strong track record and real collateral improve bank access. Weaker profiles require SGR guarantees, co-investors, or higher equity contributions.
- Target quality: stable, recurring EBITDA supports more debt. Volatile or concentrated revenue calls for more equity.
- Seller's flexibility: a seller who trusts the buyer and the transition plan is more likely to accept deferred payment or earn-out mechanics as part of the price.

Frequently asked questions about business acquisition financing
What is the minimum equity contribution lenders expect?
Most banks expect 20–30% of the purchase price in buyer equity. Below that threshold, bank financing is hard to obtain without additional guarantees or a co-investor.
Can the bank take the target company itself as collateral?
Yes. In acquisition financing, banks routinely take security over the target's assets — share pledges, mortgage over real property, or assignment of receivables.
How long does it take to get acquisition financing approved?
Six to twelve weeks with a traditional bank. That is why buyers should start the banking process in parallel with due diligence — not after it concludes.
Can I use dividends from the acquired company to repay the debt?
Yes — this is in fact the standard mechanism in leveraged buyouts. The debt is sized so that annual debt service does not exceed 60–70% of the target's free cash flow.
What do public financing instruments add to a deal?
They reduce the cost or increase the availability of debt. ICO lines offer better rates and tenors than commercial banks. SGR guarantees unlock credit for buyers who lack sufficient collateral of their own.
