Global mergers and acquisitions (M&A) reached about $3.4 trillion in total deal value in 2024, underscoring that, despite economic uncertainty, companies continue to grow through strategic deals. Yet as interest rates rise and investors become more selective, financing business acquisitions has become more complex than ever.
For many buyers, the challenge isn’t finding the right target — it’s determining how to pay for it. Should you take out a loan, bring in investors, or combine several financing sources? Each option affects cash flow, ownership, and long-term flexibility in different ways.
In this guide, we cover the essentials of business acquisition financing, from practical steps for securing funds to choosing the right capital mix. You’ll learn why companies pursue acquisition financing, how the M&A financing process works, and which funding options are available. We also explain how to estimate the amount of financing you need and how to keep the acquired business running smoothly post-close.
What is business acquisition financing?
Acquisition financing is the process of obtaining capital to fund mergers and acquisitions (M&A). It enables a business to grow, expand into new markets, or gain access to valuable technologies and customers without exhausting its own cash. In simple terms, it’s the money a company borrows or raises to buy another business.
There are many ways to structure merger and acquisition financing, depending on the deal size, the buyer’s financial profile, and the target’s valuation. Common options include bank loans, revolving lines of credit, private equity investments, mezzanine debt, and issuing new shares. In many cases, the acquirer uses a combination of cash, stock, and debt to complete the transaction. Each method carries distinct advantages, costs, and risks.
The purpose of acquisition financing is to make strategic growth possible without placing undue pressure on a company’s balance sheet. By using external capital, a business can acquire competitors, diversify its offerings, or enter new regions faster than through organic growth.
Lenders and investors evaluate the expected benefits of the acquisition—future revenue, profitability, and cost synergies—before agreeing to provide capital.

Why businesses use acquisition financing
Companies use acquisition financing to grow strategically without depleting their own cash reserves. External capital enables them to purchase other businesses, enter new markets, or acquire valuable assets while preserving liquidity and stability.
Below are the primary reasons businesses choose this type of financing:
Using external business acquisition funding allows companies to keep working capital available for operations and contingencies rather than locking it up in a transaction.
Borrowed money can support larger or multiple acquisitions that would be impossible to finance using internal resources alone.Borrowed money can support larger or multiple acquisitions that would be impossible to finance using internal resources alone.
Acquisition financing enables faster expansion into new markets, industries, or regions compared with organic strategies.
Blending debt and equity helps balance exposure and reduces pressure on the acquirer’s own capital.
In many jurisdictions, interest payments on acquisition-related debt are tax-deductible, lowering the effective cost of capital.
Companies typically need financing when they plan to:
- Buy another company or its assets
- Merge with a competitor or partner
- Acquire a brand, technology, or intellectual property
- Expand into a new market or region
- Strengthen their supply chain or distribution network
How M&A financing works
The process of financing a business purchase follows a defined path to ensure the deal is both strategic and financially sound. It begins with identifying a suitable target and ends with closing and integration.Here’s a concise step-by-step overview of how M&A financing typically works:
The acquirer selects a business that aligns with strategic goals—such as entering a new market or acquiring technology or talent—and values it using methods like EBITDA multiples and discounted cash flow (DCF). At this stage, parties often sign a letter of intent M&A to outline key terms.
The buyer evaluates how much debt the combined entity can safely carry. Many lenders consider leverage in the range of 3–5× EBITDA, depending on cash-flow stability and sector risk. This assessment sets prudent financing limits and safeguards post-close solvency.
With targets and limits defined, the buyer approaches banks, private credit funds, or equity investors. Lenders review structure, expected returns, collateral, and debt service coverage. Strong projections and a clear integration plan improve approval odds.
Once approved, the acquirer builds the capital stack—typically a mix of senior debt, mezzanine or unitranche funding, equity, and sometimes a seller note—balancing cost, risk, and control while preserving sufficient liquidity for operations.
After due diligence and documentation, the parties sign the definitive agreement and fund the deal. The buyer allocates working capital to support operations, integration, and synergy capture.
M&A financing follows a structured timeline, with each phase building on the last to ensure a seamless and financially sound acquisition:
LOI → Due diligence → Financing → Closing → Integration.

Business acquisition financing options
Companies can finance a business acquisition in several ways, depending on size, credit strength, and growth objectives. Each method has distinct benefits, trade-offs, and ideal use cases.
1. Acquisition loans
An acquisition loan is a traditional bank term loan used to buy another business. The acquirer borrows a fixed amount and repays it over time with interest.
Pros: predictable payments; the buyer retains full ownership.
Cons: requires strong credit and steady cash flow; increases leverage.
Best for: established companies with stable revenues seeking control.
Example: Tessera Technologies’ acquisition of DTS, Inc. (~$850 million) included approximately $600 million of committed debt financing.
2. Seller financing
In seller financing, the seller acts as the lender and accepts part of the purchase price over time, often through a seller note.
Pros: easier approvals and flexible terms; aligns interests between parties.
Cons: the seller assumes repayment risk; obligations persist post-close.
Best for: small to mid-market deals where speed and cooperation matter.
3. Equity financing
Equity financing raises capital from investors in exchange for ownership in the acquiring entity or combined business.
Pros: no mandatory repayments; preserves cash flow.
Cons: dilutes ownership and future profits.
Best for: high-growth buyers who prefer to avoid additional debt.
Example: BlackRock, Inc. acquired HPS Investment Partners in a deal valued at about $12 billion. The transaction included equity issued via a subsidiary convertible into BlackRock common stock.
4. Mezzanine financing
Mezzanine financing is a hybrid of debt and equity. The lender provides subordinated debt that can convert into equity under predefined conditions..
Pros: flexible terms and higher funding capacity; bridges gaps between senior debt and equity.
Cons: higher interest (often low-to-high teens) and potential dilution.
Best for: mid-market companies with strong growth and limited collateral.
Example: In 2023, Audax Private Debt raised $1.85 billion for its fifth mezzanine fund to finance middle-market acquisitions with flexible debt solutions.
5. Leveraged buyouts (LBOs)
An LBO uses a significant amount of borrowed funds to finance an acquisition, secured primarily by the target’s assets and cash flows.
Pros: enables large acquisitions with limited upfront equity.
Cons: high leverage increases risk; transaction success depends on robust cash flow.
Best for: experienced buyers and private equity firms targeting mature businesses.
Example: In September 2025, Electronic Arts (EA) announced plans to go private in a $55 billion leveraged buyout comprising approximately $20 billion in debt and $36 billion in equity.
6. Small business loans
SBA-backed loans are a common way for smaller buyers to finance a business acquisition while retaining ownership.
Pros: lower down payments and longer terms; accessible for smaller sponsors.
Cons: detailed eligibility and longer underwriting timelines.
Best for: small business owners acquiring an existing company, franchise, or local competitor.
Here’s a quick comparison of the main acquisition financing methods and when they work best:
| Financing method | Cost level | Risk level | Ideal use case |
|---|---|---|---|
| Acquisition loan | Moderate (interest payments) | Medium | Established businesses with stable income |
| Seller financing | Low to moderate | Low for buyer / High for seller | Small to mid-sized acquisitions |
| Equity financing | High (ownership dilution) | Low | Startups or fast-growing firms |
| Mezzanine financing | High (low-to-high-teens rates) | Medium to high | Growing mid-market companies |
| Leveraged buyout (LBO) | High (heavy debt) | High | Large acquisitions by private equity firms |
| SBA loans | Low to moderate | Low to medium | Smaller buyers seeking flexible terms with SBA lender support |
How much financing do you need?
The required amount depends on the purchase price, deal structure, and available capital. Most acquisitions are not financed 100% with external sources. Instead, buyers typically combine their own equity with business acquisition loans or investor capital. In most cases, 20–40% of the purchase price is funded with equity, while the remainder is covered through business acquisition loans or alternative financing structures.
Begin by valuing the target and estimating all transaction-related costs, including due diligence, legal fees, taxes, and post-merger integration expenses. Plan for working capital needs post-close to keep the acquired business operating smoothly.
Lenders and investors assess how much debt the combined entity can support using EBITDA and cash-flow metrics. Many will finance up to 3–5× EBITDA, depending on stability and sector risk. Businesses with predictable earnings can support higher leverage; those with volatile cash flows will require more equity. The goal is balance: raise enough to close and fund growth, but not so much that debt burdens future operations.
Post-acquisition operations financing
Securing a business acquisition loan gets the deal done; maintaining liquidity afterward sustains the business. Transaction proceeds are often fully allocated at closing, so buyers should plan for operating capital post-close and avoid avoidable liquidity gaps.
Both small and large business acquisition loans are often fully utilized once the company changes ownership. In such cases, you may need to seek additional funding sources or negotiate new term loans with existing lenders.
There are three main ways to finance operations post-M&A.
Self-financing
You can use your business or personal assets to fund post-acquisition operations and avoid taking on another strict term loan. This approach works best if you have a strong personal credit score and consistent cash flow.
However, just as equipment financing can put a small business at risk of debt, using your company’s capital to fund a new venture can be risky, making business acquisition loans worth reconsidering.
Loans
Traditional term loans from banks, credit unions, and online lenders follow a familiar structure. Your business may qualify based on minimum credit score requirements, a solid repayment history on prior acquisition loans, and, in some cases, collateral such as equipment.
At this stage, your main concern should be whether the interest rate aligns with your new business’s earning potential.
Invoice factoring
If you prefer to avoid further borrowing or using personal funds, invoice factoring offers an alternative. While this is one of the fastest M&A financing options, it comes at the cost of reduced revenue from those invoices.
