# Merger

A merger is the combination of two companies into one, either by one absorbing the other or by both transferring into a new entity, with the shareholders of each receiving shares in the combined business. In law most "mergers" are acquisitions in which the price is paid in shares; a true merger of equals, with neither side in control, is rare.

**Also known as:** Merger of equals, Statutory merger, Combination

## Key facts

- **Used at:** combinations where the consideration is mostly shares and both sets of shareholders continue as owners
- **Binding:** from the merger agreement; completion needs shareholder votes, and for fintechs regulatory and competition approvals
- **Exchange ratio:** the number of the combined company's shares each side's shareholders receive per share held — the price
- **Governance:** board seats, the chief executive, the name and the headquarters are negotiated alongside the ratio
- **Accounting:** one party is always the acquirer for accounting purposes, and the other's assets are revalued (purchase price allocation)

## How a merger works in practice

Two payment companies of similar size want to combine: one has the merchants, the other the technology, and neither has the cash to buy the other. A merger lets them combine without cash. The two boards agree an exchange ratio — say 0.85 shares in the combined company for each share of company A and 1 for each share of company B — which is the price in disguise: it fixes what percentage of the combined business each side's shareholders will own, and every argument about relative value ends up as an argument about the ratio.

Because there is no cash, the negotiation is about control. Who is chief executive, who chairs the board, how many seats each side has, whose name survives, which platform is kept and which is retired, where the headquarters is — each is agreed in the merger agreement, and "merger of equals" describes the ratio, not the outcome; within two years one management team usually runs the company. The shareholders of both companies vote, the competition authority reviews the combination, and for licensed businesses the regulators of each approve the change of control over the other.

Accounting refuses the fiction of equality: one company is designated the acquirer, the other's assets and liabilities are restated at fair value with goodwill for the difference, and the acquirer's own book values carry on unchanged. Which side is the acquirer changes the reported balance sheet by hundreds of millions, and auditors decide it on control, not on the press release.

## Example

Two European payment processors merge: company A, with €120m of revenue and 8,000 merchants, and company B, with €80m of revenue and the better platform. The ratio gives A's shareholders 58% of the combined company and B's 42%; A's chief executive leads, B's becomes chief operating officer, and B's platform becomes the group platform over 18 months. A is the accounting acquirer, B's net assets are revalued from €30m to €95m, and €140m of goodwill is recorded. Regulators in three countries approve the change of control over B within seven months. Two years on, €25m of annual cost savings have been delivered — the number the ratio was negotiated on.

## Common mistakes

- Negotiating the ratio on last year's numbers when the synergies are the reason for the deal.
- Settling the governance last, or leaving it vague, so the combined company has two of everything for a year.
- Ignoring the regulatory approvals each side needs for the other, which set the timetable.
- Reading "merger of equals" as a statement about who will be in charge.
- Underestimating the platform migration: a merger that keeps both platforms has bought no synergy.
