White Knight

A white knight is a friendly acquirer invited by a target company’s board of directors to make a competing bid against a hostile takeover attempt. The white knight offers an alternative to the hostile bidder, usually at a higher price or on more favorable terms. By choosing the white knight, shareholders can accept a premium to their current stock price while avoiding the uncertainty and disruption of a hostile takeover. White knights were central to takeover defence strategy in the 1980s and remain an important option.

How a white knight works

When a hostile bidder announces a tender offer or proxy fight, the target’s board has several options. One is to actively seek an alternative buyer — a white knight.

The search: The board’s investment bankers contact potential acquirers, briefing them on the company and its strategic value. The goal is to find a buyer who:

• Views the company more favorably than the hostile bidder (and thus is willing to pay more)
• Is seen as a more compatible or friendly partner
• Can close quickly and with regulatory certainty
• Can offer terms (price, structure, retention packages) that are attractive to shareholders and employees

The competing bid: Once a white knight is identified and interested, it makes a public offer to acquire the company, typically at a higher price than the hostile bidder. The white knight’s offer is usually explicitly “friendly” — it has the board’s support and endorsement.

The auction: If multiple bidders emerge (the hostile bidder and one or more white knights), shareholders are presented with a choice. Both the target’s board and the hostile bidder (and any other bidders) make their cases to shareholders. Shareholders then vote on competing proposals or wait to see which bidder accumulates the most shares through a tender offer.

In the ideal case (from the board’s perspective), the white knight wins the auction, offering a higher price than the hostile bidder and avoiding the disruption and uncertainty of a hostile takeover.

The white knight in practice

Several famous white knight rescues illustrate the dynamic:

Macmillan (1988). KKR (Kohlberg Kravis Roberts), a leveraged buyout firm, launched a hostile bid for the publishing company Macmillan. Maxwell Communications emerged as a white knight, bidding higher and winning the auction. (Maxwell later acquired competing bids and ultimately won, but the company later became highly indebted and restructured.)

RJR Nabisco (1988). The company was the subject of a legendary LBO auction. Multiple bidders competed; KKR ultimately won with an extremely high bid, but the competitive process — enabled by white knight (and competing) bidders — drove the price far higher than the initial hostile bid.

PayPal/eBay (2002). eBay emerged as a white knight to acquire PayPal in a deal more favorable to PayPal’s founders and investors than prior bidders had offered.

In all cases, the white knight mechanism created competitive tension that benefited shareholders.

Strategic considerations

A white knight must be carefully chosen. The target’s board wants a buyer who:

• Is financially capable. The white knight must have the financial resources (or financing arranged) to close the deal.
• Can obtain regulatory approval. If the white knight is in a related business, antitrust approval may be uncertain. An obscure or non-competing buyer may have easier regulatory approval.
• Will treat employees and customers fairly. If the white knight is seen as harsh or a stripper of assets, the board’s recommendation may lack credibility.
• Is compatible with the business. A white knight in an unrelated business (e.g., a financial buyer rather than a strategic buyer) may face integration challenges, but may also be more acceptable to regulators.

White knight vs. white squire

A white squire (see white squire) is a related concept: a friendly investor who purchases a large stake to block a hostile bidder, but without a full acquisition. A white squire might buy 30–40% of the company and get board representation, using its stake to negotiate with the hostile bidder or to change the company’s direction. A white knight, by contrast, goes for a full acquisition.

Advantages and limitations

Advantages:

• Shareholders benefit from a competitive auction (white knight vs. hostile bidder drives price up)
• The board retains some control over the process
• Employees and customers may prefer the white knight to the hostile bidder
• Regulatory and timing risks are managed by the board’s selection

Limitations:

• Finding a suitable white knight takes time, during which the stock is in play and uncertainty depresses valuations
• The white knight may not bid as high as a more aggressive or desperate buyer would
• If no white knight emerges, the board’s efforts to find one may have strengthened the hostile bidder’s resolve
• The white knight may have its own agenda (e.g., cost cuts, divestitures) that are not favorable to employees

When white knights are and are not viable

White knights work best when:

• The target company is strategically valuable to multiple bidders
• The hostile bidder’s valuation is seen as low
• Regulatory approval is likely for multiple buyers
• The board moves quickly to identify and court white knights

White knights are less viable when:

• Few companies have strategic interest in the target
• The hostile bidder’s valuation is already high
• Regulatory uncertainty makes it hard for others to commit
• The board has delayed seeking alternatives and time pressure limits options
