Corporate governance in mergers and acquisitions

Corporate governance plays a central role in mergers and acquisitions (M&A) by defining the framework of decision-making, accountability, and oversight for all parties involved. During M&A transactions, boards of directors, executives, and shareholders must align strategic objectives while complying with regulatory requirements and fiduciary responsibilities. Strong governance ensures that deals create sustainable shareholder value, minimize legal risks, and maintain trust among stakeholders.

Boards of directors oversee strategy and protect shareholder interests.

In M&A transactions, the board of directors has a fiduciary duty to act in the best interest of shareholders. Their responsibilities include:

• Evaluating strategic alternatives → Boards assess potential acquisitions, mergers, or divestitures against long-term growth goals.

• Reviewing deal structures → This includes assessing financial terms, valuation models, and integration plans.

• Ensuring fairness → Boards often engage independent financial advisors to provide fairness opinions on pricing and transaction terms.

• Managing conflicts of interest → Governance frameworks require directors to disclose personal or professional conflicts that could bias decisions.

An effective board provides independent oversight to balance management’s ambitions with shareholder protections.

Shareholder approval is critical for completing major transactions.

In many jurisdictions, large M&A transactions require shareholder approval before they can close. Companies must disclose transaction details in proxy statements or information circulars, enabling shareholders to make informed voting decisions.

Approval Threshold	United States	Europe	Asia-Pacific
Typical voting requirement	Majority of outstanding shares	50–75% depending on country	Varies widely by jurisdiction
Disclosure documents	SEC filings, proxy statements	Prospectuses or shareholder reports	Exchange-specific filings
Regulatory oversight	SEC, DOJ, FTC	ESMA, local authorities	Regional securities regulators

Transparent communication builds shareholder trust and reduces the risk of litigation after the transaction.

Executive compensation and incentives affect decision quality.

Corporate governance in M&A also focuses on executive pay structures and incentives, ensuring management decisions are aligned with shareholder value creation. Problems arise when compensation packages create short-term motivations, such as completing deals quickly rather than maximizing long-term returns.

Best practices include:

• Linking performance-based bonuses to integration success and synergy realization.

• Using equity-based incentives to align management interests with shareholder outcomes.

• Disclosing executive compensation details in shareholder communications for transparency.

When incentive structures are misaligned, boards risk value-destructive transactions driven by management’s personal gain.

Regulatory compliance ensures fairness and transparency.

M&A transactions are subject to strict regulatory oversight designed to prevent anticompetitive behavior and protect minority shareholders. Compliance obligations typically involve:

• Antitrust and competition laws → Ensuring deals do not create monopolistic market structures.

• Securities regulations → Requiring accurate disclosures for investors and public filings.

• Cross-border approvals → International deals often face additional regulatory reviews from multiple jurisdictions.

Failure to comply with these frameworks can result in deal delays, penalties, or cancellations, significantly impacting transaction success.

Risk management frameworks guide deal execution.

Boards and executives must evaluate potential risks associated with M&A transactions, including operational, financial, cultural, and reputational factors. Governance frameworks often establish dedicated risk committees to oversee:

• Due diligence processes on financials, contracts, and liabilities.

• Integration planning to reduce operational disruptions.

• Scenario modeling to assess downside impacts on cash flow and valuation.

Effective risk management ensures that potential challenges are anticipated and mitigated before they escalate.

ESG considerations are shaping modern M&A governance.

Environmental, Social, and Governance (ESG) factors are increasingly influencing deal strategies. Investors, regulators, and consumers expect companies to evaluate sustainability risks and stakeholder impacts when executing mergers or acquisitions.

Examples include:

• Assessing carbon footprint implications when combining supply chains.

• Evaluating workforce diversity and employee retention during integration.

• Ensuring compliance with climate-related disclosure frameworks in cross-border deals.

Companies that integrate ESG into governance frameworks often experience stronger investor support and reduced reputational risk.

Strong corporate governance drives sustainable deal outcomes.

Effective governance in M&A ensures accountability, transparency, and strategic alignment between boards, executives, and shareholders. By managing risks, ensuring regulatory compliance, and prioritizing long-term value creation, governance frameworks enable companies to execute mergers and acquisitions more successfully.
