Mergers and Acquisitions: Due Diligence Checklist for Buyers

Acquiring a business is one of the most consequential decisions a buyer can make. The price on the term sheet is only the beginning. What sits beneath the surface of a target company, its liabilities, its contracts, its compliance posture, its litigation history, can determine whether a deal creates long-term value or becomes a costly mistake. A thorough mergers and acquisitions due diligence checklist is not a formality. It is the foundation of a sound transaction strategy, and skipping it or rushing through it puts your investment at serious risk.

At Lomba, P.A., we work with buyers at every stage of the acquisition process, from early deal structuring through closing. What follows is a practical, attorney-guided framework to help you approach due diligence with the precision and discipline the process demands.

Why the Mergers & Acquisitions Due Diligence Checklist Matters

Due diligence is not about slowing a deal down. It is about protecting the deal you are trying to build. A disciplined review of the target company's legal, financial, and operational foundation gives buyers leverage at the negotiating table and prevents surprises after closing.

What you do not find before closing, you inherit. Undisclosed creditor claims, pending regulatory actions, defective intellectual property assignments, and overlapping non-compete agreements have derailed acquisitions long after purchase agreements were signed. The goal of a structured mergers and acquisitions due diligence checklist is to surface every material risk before the ink dries.

Corporate and Legal Structure Review

Start with the fundamentals. Before analyzing financials or evaluating contracts, you need to understand what you are actually buying and confirm that the seller has the authority and a clean title to sell it.

What to Request and Review

Begin by requesting the target company's certificate of incorporation or organization, bylaws, operating agreements, and all amendments. Review the full capitalization table, including all issued and outstanding equity, options, warrants, and any convertible instruments. Confirm that no equity was issued in violation of applicable securities laws and that all transfers were properly documented.

Examine board and shareholder meeting minutes going back at least three to five years. Resolutions approving major transactions, compensation arrangements, or asset transfers can reveal obligations that do not appear in financial statements. Pay close attention to any related-party transactions, which often signal conflicts of interest that need to be addressed before or at closing.

Finally, confirm that the target is in good standing in every state where it conducts business and that all required registrations, foreign qualifications, and annual filings are current.

Financial and Tax Due Diligence

Numbers tell a story, but only if you know how to read them in context. Financial review in an M&A transaction goes well beyond reviewing audited statements.

Key Areas of Financial Scrutiny

Request audited financial statements for at least three prior fiscal years, along with the most recent interim statements. Compare reported revenue and EBITDA against actual cash flows. Discrepancies between reported income and operating cash generation often indicate aggressive accounting, deferred obligations, or revenue recognition issues that will affect post-closing performance.

Scrutinize the target's debt schedule. Identify all outstanding loans, lines of credit, capital leases, and seller notes, including any that may be subject to change of control provisions triggered by the transaction. These provisions can accelerate repayment obligations or terminate favorable borrowing arrangements without notice.

On the tax side, request all federal, state, and local tax returns for the past three to five years. Review any open audits, tax disputes, or unresolved IRS correspondence. Confirm that all payroll taxes, sales taxes, and estimated taxes are current. Unresolved tax liabilities do not disappear at closing. They transfer to the buyer.

Contracts, Customers, and Key Relationships

A business is only as strong as the agreements that sustain it. Contract review is one of the most legally complex and commercially important components of any due diligence checklist for mergers and acquisitions.

Contracts That Demand Close Attention

Pull every material contract: customer agreements, vendor and supplier contracts, distributor agreements, licensing deals, and any long-term service arrangements. Look specifically for assignment clauses and change-of-control provisions. Many commercial agreements require the counterparty's written consent before they can be transferred to a new owner. A deal that closes without those consents can expose the buyer to immediate breach-of-contract exposure.

Review employment agreements, offer letters, and any executive compensation arrangements. Identify whether any employees are covered by non-solicitation or non-compete agreements, and whether those agreements are enforceable under applicable state law. Confirm that independent contractors are properly classified, as misclassification creates wage and tax liability that often surfaces post-closing.

Examine any intellectual property assignments, licensing agreements, and confidentiality obligations. Confirm that all IP developed by employees or contractors has been properly assigned to the company. Gaps in the IP chain of title can undermine the core value proposition of the acquisition.

Litigation, Regulatory Compliance, and Contingent Liabilities

Some of the most significant risks in an acquisition are the ones that do not appear on a balance sheet. Pending litigation, regulatory investigations, and contingent liabilities require careful legal analysis before closing.

Litigation History and Open Matters

Request a complete list of all current, threatened, and recently resolved legal proceedings, including arbitrations and administrative actions. Evaluate not just the dollar exposure but the nature of the claims. Repeated employment disputes, customer complaints, or regulatory enforcement patterns often signal systemic operational or cultural problems that will persist after the acquisition.

Regulatory and Compliance Review

Confirm that the target is fully compliant with all industry-specific regulations, licensing requirements, and environmental obligations. Review any correspondence with government agencies, regulatory bodies, or licensing authorities. For businesses in regulated industries, confirm that all necessary permits and licenses are transferable and that no pending regulatory action could affect them.

If the target has any exposure to merchant cash advance obligations or contested commercial debt, those matters should be reviewed with particular attention to enforcement risk, personal guarantees, and any outstanding judgments that could cloud the transaction.

Closing the Deal on Solid Ground

A complete mergers and acquisitions due diligence checklist does not guarantee a perfect deal. But it does give you the information you need to negotiate from a position of strength, structure appropriate representations and warranties, and accurately assess price risk before you commit.

The most important decisions in any acquisition happen before the purchase agreement is signed. Every issue you identify during due diligence is an opportunity to renegotiate terms, require indemnification, adjust the purchase price, or walk away entirely. Every issue you miss is a liability you absorb.
