Fairness Opinion

What Is a Fairness Opinion?

A fairness opinion is a professional assessment delivered by an independent financial advisor to the board of directors of a company involved in a major transaction — typically a merger, acquisition, or going-private deal. The opinion addresses whether the consideration to be received (or paid) is fair from a financial point of view.

Fairness opinions do not tell the board whether to approve the transaction. They address a narrower question: given the financial terms, is the price fair? The board retains full discretion over strategic, operational, and other considerations that inform the final decision.

When Fairness Opinions Are Required

Fairness opinions are most commonly obtained in:

Public company mergers and acquisitions — where the board owes fiduciary duties to shareholders
Going-private transactions — where a controlling shareholder or management team takes a company private
Related-party transactions — where conflicts of interest exist between the parties
Special committee processes — where an independent committee is formed to evaluate a conflicted transaction
Squeeze-out transactions — where a majority shareholder acquires the remaining minority shares

While not always legally required, fairness opinions have become standard practice in the broader sell-side M&A process because they provide boards with evidence of procedural fairness — helping to protect directors against shareholder litigation alleging breach of fiduciary duty.

What a Fairness Opinion Contains

A fairness opinion letter typically includes:

Scope of review — the information and materials the advisor reviewed (financial statements, projections, industry data, comparable transactions)
Methodologies employed — the valuation approaches used, typically including:
- Discounted cash flow analysis
- Comparable company analysis (trading multiples)
- Precedent transaction analysis
- Other relevant methodologies (LBO analysis, sum-of-the-parts, asset-based valuation)
Assumptions and limitations — reliance on management projections, no independent verification of data, opinion as of a specific date
The opinion — a statement that the consideration is (or is not) fair from a financial point of view

The Valuation Analysis Behind the Opinion

The fairness opinion is supported by detailed valuation work — drawing on the same methodologies covered in our M&A valuation guide — typically presented to the board in a “board book” or “fairness presentation” alongside the opinion letter:

Valuation range — each methodology produces a range of implied values, presented as a “football field” chart
Premium analysis — comparing the offered premium to premiums in comparable transactions
Historical trading analysis — assessing the offer price relative to historical share price performance
Present value of future share price — estimating what the share price could be if the company remained independent

The board evaluates whether the offered consideration falls within, above, or below the range of values indicated by these analyses.

Independence and Conflicts

The credibility of a fairness opinion depends on the advisor’s independence. Common concerns include:

Contingent fees — if the advisor’s fee is contingent on the deal closing, their incentive to deliver a “fair” opinion is questioned
Prior relationships — existing banking relationships with either party may create perceived conflicts
Stapled financing — if the same bank is providing the fairness opinion and financing the transaction

Best practice involves engaging an advisor with no material financial interest in the transaction’s outcome, or at minimum, full disclosure of any potential conflicts (Corporate Finance Institute).
