Comprehensive M&A due diligence checklist for public and private deals

You’ve been assigned a major task—your firm has put you in charge of conducting due diligence for an upcoming merger. Your work will be vital to the deal’s success, as well as to your firm’s relationship with its client. Digging into a potential acquisition, and spotting any red flags in the company’s operations is an essential job for a lawyer.

However, the amount of work that due diligence entails can make a junior attorney unsure about where to begin. The process may seem overwhelming. First things first: you need an M&A due diligence checklist.

Don’t attempt to do eight things at once—without a diligence process structure, this means you could go astray in eight different ways. With a checklist as your roadmap, you will know what you need to look for, how much time you have to find it, and who to send it to. Your job becomes far more manageable.

How do I make an M&A due diligence checklist?

An M&A due diligence checklist should start with the basic requirements of any buyer, but expand to incorporate information pertinent to the deal at hand. A good M&A diligence checklist is adaptive. It takes into account the nature of the merging entities, their management and ownership structures, their marketplaces and their histories.

Making a checklist is the best way to tackle a complex, detail-oriented, and time-sensitive task to ensure more efficient and faster M&A deals.

There’s something unique about every deal. It could be the nature of the seller’s business, or the complexity of its intellectual property holdings. The deal’s structure may be novel, or a challenge to execute. Regulators may play a determining role in whether the deal gets done.

Consider the two checklists below, which advise on how to conduct due diligence for public and private deals, to be a starting point. They are guidelines to effectively run diligence, giving tips on how to assess, organize, and present all of the resources that you collect during the process.

What should go into an M&A due diligence checklist for public mergers and acquisitions?

A public deal has many moving parts. Shareholder considerations, financial reporting obligations, equity market volatility, and other outside factors can potentially influence the deal’s progress.

Because the company is public, it will have virtual piles of information for a diligence team to go through—securities filings, quarterly reports, regulatory requirements. Lawyers will need to take a host of factors into account while still preparing for surprises along the way, even if it looks like a smooth transaction on paper.
