✦ A reverse acquisition occurs when the legal acquirer is actually the accounting acquiree, and the legal acquiree is treated as the accounting acquirer for financial reporting purposes.
✦ This situation commonly arises in private company mergers, SPAC transactions, and backdoor listings, where the smaller entity gains control over the larger one.
✦ Accounting treatment follows the substance-over-form principle, requiring reclassification of equity accounts and restatement of comparatives to reflect the accounting acquirer’s history.
✦ Complexities include share-based consideration, goodwill recognition, and compliance with business combination disclosure standards.
We’ll examine how to identify and account for a reverse acquisition, including key journal entries, equity adjustments, and IFRS/US GAAP alignment.
1. What Is a Reverse Acquisition?
A reverse acquisition occurs when:
✦ The legal acquirer (Entity A) is not the accounting acquirer.
✦ The legal acquiree (Entity B) is treated as the accounting acquirer.
✦ Typically seen when:
• A private company (B) arranges to be acquired by a public shell (A), but ends up controlling the combined entity.
• A smaller operating company merges with a larger legal entity but obtains control.
The result is that Entity B’s financials continue as the basis for reporting, even though Entity A is legally on top.
2. Control Is the Key Factor
✦ The entity that gains control of the combined business is identified as the accounting acquirer under ASC 805 (US GAAP) and IFRS 3.
✦ Indicators of control:
• Power to govern board and policies
• Right to appoint management
• Majority voting rights
• Economic interest in future profits
✦ When the legal acquirer issues equity to the owners of the legal acquiree, and those owners gain control, a reverse acquisition exists.
3. Accounting Implications
✦ The financial statements of the accounting acquirer (legal acquiree) become the ongoing financials of the combined entity.
✦ The legal acquirer’s net assets are fair-valued and included in the accounting acquirer’s consolidated financials.
✦ No goodwill is recorded by the accounting acquirer for its own acquisition—only for the fair value of the legal acquirer.
4. Equity Structure Adjustments
✦ Because the legal acquirer issues shares, the equity structure (number and type of shares) must reflect the legal parent.
✦ But the retained earnings and other equity balances are those of the accounting acquirer.
✦ Share capital is reclassified to reflect the legal capital of the legal parent.
Example:
• Legal parent (A) issues 1 million shares to acquire all of private target (B).
• B becomes accounting acquirer.
• Financials show: – Historical results of B – Equity structure as if B had always had A’s capital setup
5. Journal Entry Example — Reverse Acquisition
Assume:
• Legal acquirer (A) has net assets of $40 million
• Fair value of shares issued = $60 million
• Fair value of net assets of A = $40 million
• Goodwill = $60m – $40m = $20 million
Entry:
Dr. Net Assets Acquired (A’s assets) – $40 million
Dr. Goodwill – $20 million
Cr. Share Capital – $60 million
✦ The goodwill arises from the accounting acquirer acquiring the legal acquirer.
6. Comparative and Historical Financials
✦ The consolidated financial statements show:
• The results of the accounting acquirer (Entity B)
• As if the reverse acquisition had occurred at the beginning of the earliest comparative period presented
✦ Entity A’s pre-acquisition results are not included, even though it is the legal parent.
7. IFRS and US GAAP Alignment
✦ Both IFRS 3 and ASC 805 follow similar logic in determining the accounting acquirer based on control.
✦ Both require full acquisition accounting for the legal parent’s net assets.
✦ Equity accounts must be restated to reflect the legal structure and the economic substance.
8. Disclosure Requirements
✦ Nature of the transaction and reasons for reverse acquisition.
✦ Name of legal parent and accounting acquirer.
✦ Description of equity structure reclassification.
✦ Fair value of assets acquired and goodwill.
✦ Financial statements of the accounting acquirer (historical basis).
✦ Disclose pro forma information if required (e.g., under SEC rules).
9. Common Scenarios
✦ SPAC mergers: The private operating company becomes the accounting acquirer; the SPAC is the legal acquirer.
✦ Shell company listings: Small private firms list via reverse takeover into a public shell.
✦ Backdoor listings: Used to enter a public market without going through a traditional IPO process.
