Board Considerations in Public Company M&A Transactions

March 2026 · 7 min read

A public company M&A transaction puts a board under more scrutiny than almost anything else it will face. Shareholders, regulators, advisers, the market and the courts all look closely at the process, the decisions and the outcome. The legal framework is dense and the reputational stakes are high. Boards that approach the process well can deliver an outstanding outcome for shareholders. Boards that get it wrong can find themselves answering questions for years.

The legal framework

In Australia, public company M&A is governed primarily by:

  • The Corporations Act 2001 (Cth), particularly Chapter 6 (takeovers) and Chapter 6A (compulsory acquisition)
  • The ASX Listing Rules
  • ASIC Regulatory Guides (particularly RG 9, RG 60, RG 111 and RG 142)
  • The Takeovers Panel and its decisions
  • Common law director duties

For schemes of arrangement, additional rules under Chapter 5 of the Corporations Act apply, with court oversight.

Director duties in M**&**A

The duties that apply throughout the year apply with particular intensity in M&A:

Duty to act in good faith and in the best interests of the company. In a takeover, this is generally interpreted as acting in the best interests of shareholders as a whole.

Duty of care and diligence. Boards must inform themselves properly. This means engaging appropriate advisers, asking the right questions, and stress-testing assumptions.

Duty to avoid conflicts of interest. Directors with personal interests in the transaction must declare them, and may need to step aside from board deliberations.

Duty of good faith to shareholders. In a takeover, the board must engage with bidders fairly, not block legitimate bids, and not act to entrench management.

The bid process

When a bid lands, the board's first decisions matter:

  • Establish a board committee (often excluding any conflicted directors)
  • Appoint financial and legal advisers
  • Manage information flow to the market and regulators
  • Consider whether to engage with the bidder
  • Decide on response strategy (recommend, reject, defend, run a process)

The Takeovers Panel and ASIC are particularly attentive to defensive measures that might frustrate bids, including share issues, asset disposals and break fees.

The independent expert**'**s report

Most public M&A transactions will require an independent expert's report (IER). For schemes, the IER opines on whether the scheme is in the best interests of shareholders. For takeovers, the IER addresses whether the offer is fair and reasonable.

Boards must ensure the expert is genuinely independent, well-briefed, and given full access to information.

Disclosure and announcements

Public M&A transactions are continuous disclosure events. The board needs to manage:

  • Initial announcements (NBIO received, due diligence access granted, etc.)
  • Trading halts and information leaks
  • Bidder's statements and target's statements (or scheme booklets)
  • Variations and updates
  • ASIC and ASX engagement
  • Communications with major shareholders

Selective disclosure to favoured shareholders is a particular sensitivity.

Process and documentation

A well-documented process is one of the board's best protections against later challenge. This includes:

  • Detailed minutes of board and committee meetings
  • Records of advice received and considered
  • Notes of engagement with the bidder
  • Documentation of the rationale for board decisions
  • Maintenance of the conflict register

Common pitfalls

Pitfall 1: Treating the bid as a distraction. A bid is one of the most consequential events in a company's history. It deserves prime board attention.

Pitfall 2: Inadequate engagement with the bidder. Boards that refuse to engage can be accused of frustrating shareholder choice. Engage, but on appropriate terms.

Pitfall 3: Defensive measures. Issuing shares, granting options, signing material contracts or undertaking material asset disposals during a bid period invites Takeovers Panel scrutiny.

Pitfall 4: Conflicts. Directors with personal interests in the transaction must be carefully managed. Failure to do so undermines the integrity of the process.

Pitfall 5: Selective communication. Communications must be even-handed. Favouring the bidder, or favouring some shareholders over others, creates legal exposure.

Pitfall 6: Inadequate documentation. Where decisions are challenged later, the contemporaneous record is what counts. Good minutes are not optional.

Pitfall 7: Adviser selection. Conflicted advisers (for example, those who also act for the bidder) create immediate problems. Choose advisers carefully.

Friendly vs hostile

The dynamics differ significantly between friendly and hostile situations:

  • Friendly bids typically proceed by scheme of arrangement, with a comprehensive scheme implementation deed and target board recommendation.
  • Hostile bids typically proceed by takeover offer, with the target board responding through a target's statement and potentially defensive actions.

A bid can also evolve from hostile to friendly, or vice versa, mid-process. Boards need to remain agile.
