Tender Offer Requirements

A tender offer is an offer to buy shares directly from shareholders, typically at a premium to current market price, to facilitate a merger or acquisition. U.S. law, primarily the Williams Act (1968), requires the bidder to disclose terms, give shareholders time to consider, and follow specific procedural rules to prevent coercion and surprise.

The Williams Act and its purpose

Before 1968, a company could accumulate stock quietly and then launch a surprise hostile acquisition bid—a “Saturday night special.” Target shareholders had limited time to react and little information. The Williams Act, passed in 1968, changed this by requiring full disclosure and giving shareholders time to consider.

The core rule: if a person or company acquires 5% or more of a company’s voting shares, it must file a Schedule 13D with the SEC within 10 days, disclosing identity, source of funds, intentions (passive investor, activist, control bid, etc.), and any plans to restructure the target.

The tender offer process

When an acquirer decides to make a formal offer to buy all or most shares at a specified price, it must:

1. Announce the offer with an offer document (materials sent to shareholders).
2. File with the SEC (Schedule 14D-1) disclosing the offer terms.
3. Maintain the offer for at least 20 business days from the date the offer is first published.
4. Allow shareholder withdrawal: shareholders who tender their shares have the right to withdraw them during the offer period if the offer is not yet complete.
5. Disclose subsequent offers: if the bidder raises the offer price or extends the offer, shareholders must be told and often get additional withdrawal rights.

Key disclosure requirements

The tender offer document must include:

• Source of funds: How the bidder will finance the acquisition (cash, debt, stock, etc.). This is critical; if the bidder lacks funds, the offer is fragile.
• Bidder’s plans: What will happen to the target’s business, management, facilities, and employees. A bidder planning to break up the company must say so.
• Conflict of interest: If the bidder or its affiliates have relationships with the target that might cloud judgment.
• Recent transactions: Any recent dealings between bidder and target (prior negotiations, stock purchases, etc.).
• Tax treatment: Whether shareholders will face capital gains tax on tendered shares.

The target company is required to respond with its own disclosure (Schedule 14D-9), often recommending shareholders accept or reject the offer, or stating that the board is evaluating it.

Minimum offer period and shareholder protections

The 20 business day minimum is designed to prevent coercion. If an offer expired in 2 days, shareholders might panic-tender shares rather than miss the window. With 20+ days, shareholders can:

• Consult advisors (investment banks, lawyers, accountants).
• Evaluate the offer price relative to the company’s intrinsic value.
• Seek alternative bids (the board may solicit competing offers).
• Vote on any countermeasures (poison pills, etc.).

If the bidder raises the offer price after the initial offer period, shareholders get additional time to reconsider. This ensures that even late-deciding shareholders are not locked out.

Two-tier and coercive offers

Some hostile bidders use a two-tier offer: a high price for shares tendered quickly (e.g., $50 cash) and a lower price for remaining shareholders (e.g., $40 in stock). This creates urgency: shareholders who wait risk getting the lower price.

The Williams Act and SEC rules allow two-tier offers but require upfront disclosure of both tiers and equal treatment for all shareholders within each tier. The bidder cannot surprise shareholders by lowering the back-end price after many shareholders have tendered.

Regulators view purely coercive offers (where the back-end is far less attractive) with skepticism, though they are technically allowed if disclosed.

Conditions and termination

A tender offer can include conditions:

• Minimum tender condition: The offer lapses if fewer than, say, 50% of shares are tendered (no control achieved).
• Financing condition: The offer lapses if the bidder cannot secure debt or equity funding.
• Regulatory approval: The offer lapses if antitrust authorities block it.

These conditions must be disclosed upfront. If a condition is not met and the offer lapses, shareholders are released and can sell elsewhere.

Defensive tactics and board role

When a hostile tender offer is made, the target board is obligated to consider shareholder interests. It may:

• Recommend acceptance (if the board concludes the offer is fair).
• Recommend rejection (if the offer is low or the company is worth more).
• Seek alternative bids (call other bidders to create competition, driving price up).
• Implement a poison pill (a shareholder rights plan that makes the target less attractive to the acquirer; see anti-dilution provisions).
• Accelerate a merger with a white knight (a friendly acquirer at a higher price).

Comity and international offers

When a foreign acquirer makes a bid for a U.S. company, the Williams Act applies. Conversely, a U.S. company bidding for a foreign target may have to comply with that country’s laws as well. The EU, UK, and other jurisdictions have similar tender offer rules (the Takeover Directive in the EU).

Regulatory arbitrage sometimes occurs: a bidder might structure the acquisition to minimize regulatory friction (e.g., filing in a jurisdiction with lighter disclosure rules if possible, though this is increasingly policed).

Timing and practical reality

In practice, a hostile tender offer is the nuclear option. Before launching an offer, the bidder often:

1. Quietly accumulates shares up to 5% (then files Schedule 13D).
2. Makes a private offer to the target board (which the board rejects).
3. Goes public with a tender offer and public pressure (activism + bid).
4. Negotiates terms while the offer is pending.

Most hostile bids eventually settle in negotiation. Very few run through to completion with shareholders tendering en masse; by then, either a deal is struck or the bidder withdraws.
