Two-Step Acquisition
An M&A transaction structure combining a tender offer for a majority of the target's shares with a subsequent back-end merger to acquire the remaining minority shares.
What Is a Two-Step Acquisition?
A two-step acquisition is a transaction structure in which the acquirer first conducts a tender offer to purchase a majority of the target company’s outstanding shares directly from shareholders, and then completes a back-end merger to acquire the remaining shares held by non-tendering shareholders. The two-step structure can be significantly faster than a one-step merger because the tender offer does not require a shareholder meeting or proxy solicitation.
Two-step acquisitions are one of the two primary structures for acquiring US public companies, alongside the one-step merger.
How It Works
Timeline Comparison
| Step | Two-Step Acquisition | One-Step Merger |
|---|---|---|
| Definitive agreement | Day 0 | Day 0 |
| SEC filing | Day 1-5 (Schedule TO) | Day 10-15 (Preliminary Proxy) |
| Minimum period | 20 business days (tender offer) | 30-40 days (proxy mailing to meeting) |
| Shareholder action | Tender shares (no meeting) | Vote at meeting |
| First step completion | Day 20-30 | Day 45-60 |
| Back-end merger | Day 25-35 | N/A (single step) |
| Total timeline | 25-35 days | 45-60+ days |
The Two Steps
Step 1: Tender Offer
- Acquirer launches a tender offer at the agreed price
- Offer is open for a minimum of 20 business days
- Target shareholders choose whether to tender their shares
- Minimum condition precedent: typically a majority of outstanding shares
- Upon satisfaction of conditions, acquirer purchases tendered shares
Step 2: Back-End Merger
- After the tender offer closes, acquirer owns a majority of target shares
- If the acquirer owns 90%+, it completes a short-form merger (squeeze-out) without a vote
- If below 90%, the acquirer may exercise a top-up option to reach 90%, or call a shareholder meeting
- Remaining minority shareholders receive the same per-share price as tendering shareholders
Key Structural Elements
| Element | Description |
|---|---|
| Minimum tender condition | Majority of outstanding shares (sometimes higher) |
| Top-up option | Right to purchase newly issued shares to reach 90% threshold |
| Subsequent offering period | Additional 3-20 business day period for shareholders to tender after initial results |
| Best price rule | All tendering shareholders must receive the same price |
| Same price requirement | Back-end merger price must equal the tender offer price |
Advantages and Disadvantages
Advantages
- Speed — 20-30 days faster than a one-step merger
- Certainty — no risk of a failed shareholder meeting
- No proxy statement — avoids SEC review of a proxy statement (though Schedule TO is filed)
- Tender directly — shareholders act individually rather than through a collective vote
- Partial results visible — can gauge acceptance before committing to the back-end
Disadvantages
- Two-step process — requires both a tender offer and a merger (more documentation)
- Top-up mechanics — if 90% not reached, additional steps needed
- All-holders/best-price — rules require identical treatment of all shareholders
- Financing complexity — must fund the tender offer before the merger closes
When to Use Two-Step vs One-Step
| Factor | Favours Two-Step | Favours One-Step |
|---|---|---|
| Speed is critical | Competitive auction, hostile approach | Standard bilateral negotiation |
| Shareholder base | Dispersed, institutional shareholders likely to tender | Concentrated, controlling shareholder |
| Regulatory approvals | Can be obtained within tender offer period | Lengthy approvals favour one-step timeline |
| Financing | Available at tender offer launch | Bridge to permanent financing needed |
According to analysis by Wachtell, Lipton, Rosen & Katz, two-step acquisitions have become increasingly common in US public company M&A, particularly for transactions under $10 billion where speed to closing is a priority.
APAC Context
Australia — Australian takeover law provides a functionally similar two-step process through the off-market takeover bid (Part 6.5 of the Corporations Act). The acquirer launches a bid, and if it reaches 90% acceptance, it can proceed to compulsory acquisition of the remaining shares. The minimum offer period is one month.
Japan — Japanese law requires a tender offer (TOB) for acquisitions of listed companies above certain thresholds. Following a successful TOB, the acquirer can use a share cash-out procedure (kabushiki tō uriwatashi seikyū) to acquire remaining shares if it holds 90%+ of voting rights.
India — SEBI’s Takeover Regulations mandate an open offer when an acquirer crosses specified ownership thresholds. The open offer and subsequent delisting process functions as India’s version of the two-step acquisition, though the delisting threshold (90%) and reverse book building process add complexity.
“The two-step acquisition is the fastest path to 100% ownership of a public company,” notes Daniel Bae, founder of Amafi. “In APAC, while the specific mechanics vary by jurisdiction, the same two-step logic — majority acquisition followed by minority squeeze-out — applies across markets.”
