---
A tender offer is a public bid to purchase some or all of a company's shares directly from shareholders, typically at a premium above the current market price. They are the mechanism behind many major acquisitions and share buyback programmes, and for investors holding a target company's stock, a tender offer is one of the most consequential events that can happen.

## What Is a Tender Offer?

A tender offer is a formal, public offer made by an acquirer (which can be another company, a private equity firm, or the company itself) to purchase shares from existing shareholders at a specified price, for a specified period of time.

**Key characteristics**:
- **Premium price**: The offer price is almost always above the current market price, typically 20–40% higher, to incentivise shareholders to sell
- **Fixed window**: Shareholders have a defined period (minimum 20 business days under SEC rules) to "tender" (submit) their shares
- **Conditional or unconditional**: The offer may be conditioned on receiving a minimum percentage of shares (e.g., 50% + 1 share for majority control)
- **Directly to shareholders**: Bypasses the board of directors, acquirers go straight to shareholders, which is why hostile takeovers often use this method

## Types of Tender Offers

### Third-Party Tender Offers (M&A)

*Tender offers fall into two main categories: third-party M&A bids and issuer buybacks.*

The most common type, one company offers to buy shares in another company:

**Friendly**: The target board has negotiated and supports the deal. The offer is typically made after a merger agreement is signed.

**Hostile**: The acquirer approaches shareholders directly without board approval. If the board rejects a buyout approach, the acquirer can launch a tender offer over the board's objection, hoping shareholders accept independently.

### Issuer Tender Offers (Share Buybacks)

A company can tender for its own shares, essentially a large-scale, structured buyback. Two forms:

**Fixed-price tender offer**: The company offers to buy a set number of shares at a fixed premium (e.g., 15% above market) for 20 business days.

**Dutch auction tender offer**: Shareholders specify the minimum price at which they're willing to sell within a range. The company tabulates all submissions and sets the clearing price, the lowest price at which it can buy the desired number of shares. All tendering shareholders at or below the clearing price receive that clearing price.

## The Tender Offer Process

1. **Announcement**: The acquirer files a Schedule TO with the SEC and issues a public press release announcing the offer price, offer period, and conditions
2. **Offer to purchase**: A detailed document sent to all shareholders explaining the terms, the acquirer's plans, and the rationale
3. **Board recommendation**: Target company's board files a Schedule 14D-9 recommending shareholders accept or reject
4. **Tendering period**: Shareholders have at least 20 business days to tender shares through their brokers
5. **Proration** (if oversubscribed): If more shares are tendered than the acquirer wants to buy, shares are purchased on a pro-rata basis
6. **Closing**: Payment is made to tendering shareholders; acquirer takes ownership

*The six steps from announcement to closing in a typical tender offer.*

## Regulatory Framework

Tender offers in the US are governed by the **Williams Act** (1968), which added Sections 13(d), 13(e), and 14(d) to the Securities Exchange Act:

- **20-business-day minimum**: Shareholders must have at least 20 business days to decide
- **Best price rule**: All shareholders who tender during the offer period must receive the same (highest) price
- **Withdrawal rights**: Shareholders can withdraw tendered shares at any time during the offer period
- **Proration rights**: If the offer is oversubscribed, shares must be purchased on a pro-rata basis

## Arbitrage in Tender Offers

When a tender offer is announced, the target company's stock typically trades just below the offer price, not at it. The gap reflects:

- **Completion risk**: The deal might not close (regulatory rejection, financing failure, material adverse change)
- **Time value**: The deal takes weeks or months to close

**Merger arbitrageurs** (risk arb funds) exploit this gap, buying the target's stock after announcement and profiting when the deal closes at the higher offer price. The return is small (1–5%) but relatively low-risk when spread across many deals.

## What Tender Offers Mean for Investors

**If you own the target**:
- You'll typically receive an offer price 20–40% above where the stock was trading
- You can tender all, some, or none of your shares
- If you don't tender and the acquirer gets majority control, you may be subject to a subsequent merger squeeze-out at the same price
- Monitor for competing bids, sometimes a higher offer emerges after the initial announcement

**If you own the acquirer**:
- Acquisitions often cause the acquirer's stock to drop on announcement (market skepticism about premium paid and integration risk)
- Watch the deal rationale, synergy estimates, and how the deal is being financed (cash vs. stock vs. debt)

## Conclusion

A tender offer is the direct-to-shareholder mechanism for major corporate acquisitions and buybacks. The premium above market price creates immediate value for shareholders of the target company, while the regulatory framework ensures fair treatment for all holders. Whether you own a company that becomes a takeover target or you're tracking deal activity in your portfolio, understanding how tender offers work, and when they succeed or fail, is core knowledge for any investor.
