White Knight White Squire: Friendly Takeover Defenses

Key Takeaways

• A white knight acquires the whole target on terms the board prefers; a white squire takes a minority blocking stake to preserve independence.
• Once the board accepts that a sale is inevitable, Revlon duties require it to maximize price, picking a friendly buyer at a lower price violates this duty.
• White squire investments (like Berkshire's 1989 Gillette preferred) avoid triggering Revlon because independence is preserved, not a sale.
• Standstill agreements in squire deals restrict what the friendly investor can do later; a squire who turns hostile undermines the entire structure.

What It Is

In takeover defense, the white knight is a third party that the target's board prefers, and that delivers a competing offer at a price the board can recommend. The hostile bidder (the "black knight") may walk away, raise its bid, or force an auction.

The white squire is a different structural answer. Rather than a full sale, the target sells a meaningful minority block (often 15 to 25 percent) of preferred or common stock to a friendly investor. The squire's stake plus the existing board's voting alignment is large enough to block any hostile takeover that requires shareholder approval, while leaving the target independent.

The Intuition

A board that wants to keep the company independent has limited tools. A poison pill creates leverage but eventually runs out. A staggered board buys time but not forever. The white knight offers an exit on terms the board can defend in court. The white squire offers continued independence at the cost of issuing equity to a friendly party.

Both tactics surface a Delaware fiduciary question. Once the board decides the company will be sold, the Revlon doctrine kicks in: directors must act as auctioneers maximizing immediate stockholder value. They cannot pick a friendly bidder at a worse price simply because they prefer the buyer.

How It Works

A white knight transaction follows a standard sequence.

1. Hostile bid arrives. A bidder makes a tender offer or proposes a merger the board considers inadequate. The board adopts or maintains a pill and forms a special committee.

2. Auction or limited solicitation. Bankers contact a curated list of potential acquirers, often under nondisclosure agreements with standstill provisions.

3. Knight emerges. A friendly bidder offers a higher price, better deal protection, or a more credible regulatory profile.

4. Merger agreement. The target signs with the knight, including a termination fee, a no-shop or limited go-shop clause, and a fiduciary out. The pill is redeemed.

A white squire investment follows a different path.

1. Private placement. The target issues new convertible preferred or common to the squire at a negotiated price, typically with a multi-year standstill, voting agreement, and limited transfer rights.

2. Voting alignment. The squire commits to vote with the board on change-of-control matters, locking in a voting bloc that any hostile acquirer must overcome.

3. Long-term partnership. The squire often takes a board seat and becomes a stable holder. Examples include Berkshire Hathaway's preferred stakes in several large companies during periods of distress.

Worked Example

In 1985, Pantry Pride launched a hostile tender offer for Revlon. Revlon's board rejected the bid, adopted a poison pill, and pursued a leveraged buyout with Forstmann Little as the white knight. The board agreed to a "lockup" giving Forstmann the right to buy two key Revlon divisions at a discount, plus a no-shop clause and a $25 million breakup fee.

The Delaware Supreme Court held that once the board concluded Revlon would be sold in some form, its duty became to maximize immediate stockholder value, not to protect a chosen bidder. The lockup and no-shop provisions, designed to favor Forstmann, breached that duty. The injunction stood, and the case became the basis of "Revlon duties" that constrain every white knight transaction since. Boards can pick friends, but only at the highest price the market will pay.

White squire transactions, such as Berkshire Hathaway's 1989 preferred investment in Gillette during its takeover battle with Revlon's Ronald Perelman, illustrate the alternative: a large friendly minority that blocks bids without triggering Revlon.

Common Mistakes

1. Confusing knight with squire. A knight buys the company. A squire takes a minority stake. The two solve different problems and trigger different fiduciary regimes.

2. Ignoring Revlon duties. Once a sale becomes inevitable, the board cannot prefer a friendly bidder at a discount. Lockups, breakup fees, and no-shop clauses must withstand auction-duty scrutiny.

3. Underestimating standstills. White squire deals always include multi-year standstills that limit what the squire can do later. A squire who later turns hostile or sells to a hostile party undermines the whole structure, so deal documents protect against that.

4. Treating the friendly bidder as risk-free. Knights often demand operational concessions, board seats, or breakup protections that limit subsequent flexibility. A poorly negotiated knight deal can leave shareholders worse off than a moderate hostile bid.

5. Forgetting the regulatory overlay. Squire investments involve Hart-Scott-Rodino antitrust filings above thresholds and Schedule 13D disclosure once 5 percent is crossed. Knight transactions involve full HSR review and SEC merger proxies.

Frequently Asked Questions

Q: What is the difference between a white knight and a white squire? A white knight buys the entire company at a price the board prefers over the hostile bid. A white squire takes a minority stake (typically 15–25%) to give the board a blocking vote against the hostile acquirer, preserving the company's independence. The knight solves the problem by selling the company on better terms; the squire solves it by keeping the company independent.

Q: How do white knight and squire defenses affect investment decisions? A white knight transaction triggers Revlon duties: the board must now maximize price, not simply pick a friendly buyer. For merger-arb investors, the arrival of a white knight usually widens the bid from the hostile party or creates a genuine auction, both of which are value-enhancing. A white squire investment dilutes existing holders and typically trades at a discount to a change-of-control transaction.

Q: What is a real-world example of Revlon duties applying to a white knight? In Revlon v. MacAndrews (1986), Revlon accepted Forstmann Little as a white knight over Pantry Pride, including a lockup giving Forstmann the right to buy two key divisions at a discount. Delaware's Supreme Court enjoined the lockup: once a sale was inevitable, the board had to maximize price, not protect Forstmann. The lockup violated Revlon duties by ending the auction.

Q: How can investors use a white squire investment as a signal? A white squire stake signals that the board has found a friendly large shareholder willing to block hostile bids at the current price level. Check the standstill agreement terms, how long does it run, and what are the squire's restrictions on selling to a third party? A squire who can transfer freely is less protective than one with strict lockup provisions.

Q: How is a white knight different from a go-shop process? A white knight is solicited after a hostile bid has arrived, the board is under immediate threat. A go-shop is a contractual period built into a signed friendly deal that lets the board actively solicit alternatives to the first signed offer. The legal pressures differ: a go-shop operates under Revlon auction duties from the start; a white knight scenario triggers those duties only once the board accepts a sale is inevitable.
