What is a reverse acquisition, and how do you identify the accounting acquirer?

A reverse acquisition occurs when the entity that issues securities (the legal acquirer) is NOT the accounting acquirer. The entity whose former shareholders end up with the majority control of the combined entity is deemed the accounting acquirer — even though it was technically "acquired."

When Does This Happen?

Reverse acquisitions commonly occur when a small private company arranges to be "acquired" by a larger public shell company (or a smaller public company) to gain a stock exchange listing without an IPO. After the transaction:

• The legal acquirer (public shell) issued the shares
• The legal target (private company) shareholders control the combined entity
• The private company is the accounting acquirer

Identifying the Accounting Acquirer (IFRS 3 / ASC 805):

The entity that obtains control is the acquirer. In cases of doubt, consider:

1. Which entity's shareholders hold the majority of voting rights in the combined entity?
2. Which entity's management runs the combined entity?
3. Which entity is larger (assets, revenue)?
4. Which entity initiated the combination?

Worked Example — Marlin Resources (Private) & Beacon Corp (Public Shell):

Beacon issues 8,000,000 new shares to acquire Marlin. Before the deal:

• Beacon: 2,000,000 shares outstanding
• Marlin: (private, no listed shares)

After the deal:

• Beacon outstanding shares: 10,000,000
• Former Marlin shareholders own: 8,000,000 / 10,000,000 = 80%
• Former Beacon shareholders own: 2,000,000 / 10,000,000 = 20%
• Marlin's former CEO becomes CEO of the combined entity

Result: Marlin is the accounting acquirer even though Beacon legally acquired Marlin.

Consolidated Financial Statements:

The consolidated statements reflect:

• Marlin's historical financial statements as the continuing entity
• Beacon's assets and liabilities remeasured at fair value (as the "acquired" entity)
• Goodwill calculated based on the fair value of Beacon minus Beacon's net asset fair values
• The equity section reflects Beacon's legal capital structure (share count, par value) but Marlin's historical retained earnings

Goodwill Calculation:

The "consideration" is the fair value of the equity interest that the accounting acquirer (Marlin) would have had to issue to give Beacon's shareholders the same 20% ownership.

Key Exam Points:

1. The accounting acquirer is the entity whose shareholders control the combined entity.
2. The legal acquirer's pre-acquisition financial statements are discarded — the accounting acquirer's historical statements continue.
3. Goodwill is calculated from the perspective of the accounting acquirer acquiring the legal acquirer.
4. This is common in reverse mergers (backdoor listings).
