A merger or acquisition is one of the most consequential decisions a business can make. It’s also one of the most common places where board governance breaks down because the line between oversight and operations can blur quickly when the stakes are high and the details are moving fast.
Our team has guided clients through these transactions and has seen the full spectrum.
Boards that ask the right questions at the right time can meaningfully strengthen a deal. Boards that blur the line between oversight and operations can slow the process, introduce confusion, and in some cases, jeopardize the outcome. The core principle boards should return to throughout any M&A process is that they are there to offer high-level guidance, not operational control.
In this blog, we’ll cover what fiduciary duties are required by a board during an M&A, where they areas of due diligence they can focus on to help guide the overall organization, where a special committee might be necessary, and what happens after the deal is sealed.Our team has guided clients through these transactions and has seen the full spectrum.
The Fiduciary Foundation
There are two primary fiduciary duties a board must satisfy in any M&A transaction: the duty of care and the duty of loyalty. The duty of care requires directors to act as reasonable, prudent people given the circumstances. The duty of loyalty requires that every decision be made in the best interests of the organization, as opposed to those of individual directors or management.
Courts assess a range of factors when evaluating whether a board met these obligations, including attendance at meetings, time spent deliberating, advice sought from third-party experts, and the thoroughness of document review. From our point of view, a board that is engaged and informed is good governance and legal protection.
Due Diligence: The Board’s Questions Matter
Management will drive the due diligence process. The board’s role is to pressure-test its assumptions.
Effective board governance in M&A means asking incisive questions, insisting on a thorough analysis, and challenging assumptions. Be careful not to overstep into micromanagement.
Before approving any transaction, here are four areas a board should push hard on:
- Mission and strategic alignment. Is this deal consistent with where we’re going? A transaction that looks financially attractive but pulls the organization away from its mission and vision is a bad deal, regardless of the numbers.
- Financial condition of the target. Do we have a deep, honest understanding of what we’re acquiring? This means reviewing financials at a minimum, and includes understanding liabilities, quality of earnings, and working capital needs. What are we actually buying, and what comes with it?
- Organizational capacity. Can we withstand this? Mergers almost always come with disruption, and workforce turnover can be significant. Research tells us that nearly half (47%) of key employees leave a company within a year of the transaction, and that 75% leave within the first three years. Before approving a transaction, a board must be clear-eyed about the disruption an M&A introduces and be able to answer the question: Can we withstand that level of instability, and do we have a plan for it?
- A clear vision for success. What does this look like at six months, one year, five years? The board should insist on a definition from management on what a successful outcome looks like in measurable terms.
Do You Need a Special Committee?
This question comes up often, and the answer depends on your situation.
Establishing a special committee is a common corporate governance practice in the context of transactions involving insiders, controlling stockholders, or other related persons, so-called “conflict transactions.” Special committees are designed to create a record of independent decision-making.
That said, a special committee isn’t always necessary or even advisable. Forming a special committee is not costless, and it shouldn’t be viewed as a default approach or a shield from litigation. Establishing a special committee where the facts don’t call for it can burden the company with an inefficient decision-making process and even jeopardize a proposed transaction that could otherwise be in the best interests of stakeholders.
For many organizations – especially those with smaller boards – delegating M&A oversight to an existing committee, or forming an informal working group of directors with relevant experience, is a more practical approach. The goal is independent, informed oversight. The structure that achieves it will look different for a three-person board than for a fifteen-person one.
A quick note about independent advisors: it’s considered a best practice to get a third-party fairness opinion for significant transactions. If the deal is large, complex, or involves parties with potential conflicts, independent advisors such as legal counsel, financial experts, or industry specialists should be brought in.
After the Deal Closes
Once the agreement is signed, the board moves into post-merger oversight. This phase requires the same discipline as the approval process.
In practice, this means receiving regular updates on integration progress without getting into operational details. The dynamic on the ground changes quickly and the board doesn’t need to track every development. What it does need to know is whether the goals that justified the deal are still on track, and whether any material risks have emerged.
From first evaluation to final approval, the board’s role is to ensure the organization makes a decision it can stand behind, and support the work required to make it succeed.

Frequently Asked Questions (FAQs)
What fiduciary duties does a board of directors have during an M&A transaction?
Board directors have two primary fiduciary duties in any M&A transaction: the duty of care and the duty of loyalty. The duty of care requires directors to act as reasonably prudent decision-makers, while the duty of loyalty requires every decision to prioritize the best interests of the organization over any individual director’s or management’s personal interests.
What is the board of directors’ role in M&A due diligence?
The board’s role in due diligence is to pressure-test management’s assumptions rather than manage the process directly. This includes asking hard questions about strategic alignment, the target’s financial condition, organizational capacity to absorb the transaction, and what a measurable, successful outcome looks like.
When does an M&A transaction require a special committee?
A special committee is typically warranted when a transaction involves insiders, controlling stockholders, or other conflicts of interest. Its purpose is to create a clear record of independent decision-making. However, it isn’t always necessary; for smaller boards, delegating oversight to an existing committee or an informal working group of qualified directors is often more practical.
What happens to the board’s role after an M&A deal closes?
Post-close, the board shifts into integration oversight. This means receiving regular updates on whether integration goals are on track and monitoring for material risks, without getting pulled into operational details. The same discipline that guided the approval process should carry through the integration phase.
Do boards need an independent advisor for M&A transactions?
For significant transactions, yes. It is considered best practice to obtain a third-party fairness opinion, particularly when a deal is large, complex, or involves parties with potential conflicts of interest. Independent legal counsel, financial experts, or industry specialists provide both substantive guidance and an important layer of legal protection for the board.
