The White Squire: Technical Mechanics of Strategic Minority Investments

引导语：White Squire（白衣护卫）是公司在不失去独立性的前提下，抵御敌意收购的一种精准策略。本文从战略少数股权投资、不扩持协议（Standstill Agreement）以及表决权锁定三个维度，深度解析其运行机制，为企业在控制权保卫战中的“伙伴选择”提供决策参考。

TL;DR: A White Squire is a friendly investor (individual or corporation) who acquires a significant minority stake in a company that is being targeted by a hostile raider. Unlike a White Knight, who buys the entire company, the White Squire only buys enough shares (usually 15% to 25%) to make a hostile takeover mathematically impossible. Technically, the Squire is a "Long-term Partner" who signs a Standstill Agreement, promising not to launch their own takeover and to vote their shares in favor of the current board. This allows the target company to remain independent while creating a "Block" of friendly votes that any raider would struggle to overcome.

🔄 The White Squire Protection Cycle

The following diagram illustrates the technical process of using a strategic minority investment to paralyze a hostile takeover attempt:

🏛️ Technical Framework: The "Standstill Agreement"

The Standstill Agreement is the technical glue that holds the White Squire defense together.

• The Restriction: The Squire agrees that for a period of 5 to 10 years, they will not increase their stake beyond a certain percentage (e.g., they stop at 19.9%).
• The Voting Proxy: The agreement usually requires the Squire to vote their shares as directed by the board, effectively giving the board a "Vested Voting Block."
• The Exit: If the Squire wants to sell their shares, the target company often has a Right of First Refusal (ROFR), ensuring the shares don't end up in the hands of another raider.

⚙️ The "Section 203" Leverage (DGCL)

In Delaware, a White Squire can be used to trigger statutory protections under Section 203 of the DGCL.

1. The Rule: A raider who buys more than 15% of a company without board approval is banned from completing a "Business Combination" (merger) for 3 years.
2. The Squire's Role: By selling 20% to a White Squire with board approval, the board proves that they are not "Anti-Merger," they are just "Anti-Raider." This makes it easier to defend against lawsuits claiming the board is being obstructive.

🛡️ Judicial Scrutiny: "Unocal" and "Blasius"

Because a White Squire defense involves issuing new shares (diluting other shareholders), it faces high judicial scrutiny.

• The Unocal Test: The board must prove the investment was a "Proportionate Response" to a threat.
• The Blasius Standard: If the board issues shares to a White Squire solely to "thwart a shareholder vote," it is technically illegal unless the board has a "Compelling Justification." Courts are very protective of the Shareholder Franchise (the right to vote).

🔍 Forensic Indicators of a White Squire Defense

Analysts look for these signals that a board is "Shoring up its defenses":

• Private Placement of Preferred Stock: A sudden sale of convertible preferred stock to a single large investor (like a pension fund or Berkshire Hathaway).
• Expansion of Board Seats: Adding 1 or 2 seats specifically for the representatives of a "Strategic Partner."
• "Standstill" Filings: A Schedule 13D filing from a large investor that includes the text of a restrictive standstill agreement.

• Gillette vs. Coniston Partners: The Buffet Squire: Analyze how Warren Buffett’s Berkshire Hathaway acted as a White Squire for Gillette, protecting the company from a hostile bid while earning a high dividend.
• Polaroid vs. Shamrock Holdings: The ESOP Squire: Explore how Polaroid used an Employee Stock Ownership Plan (ESOP) as a "Technical White Squire" to put 14% of the shares in the hands of friendly employees.

Frequently Asked Questions (FAQ)

What is the difference between a White Knight and a White Squire?

A White Knight buys the whole company. A White Squire buys just enough to help the board say "No" to the raider.

Does a White Squire get a "Discount"?

Often, yes. To attract a Squire to a "Battle Zone," the company might sell them shares at a slight discount to market price or give them a higher dividend on preferred stock.

Can a White Squire turn "Hostile"?

This is the board’s biggest fear. If the Standstill Agreement expires or has a "Loophole," the Squire can use their 20% stake as a platform to launch their own hostile takeover. This is why the contracts are written with extreme technical precision.

Is it legal to dilute shareholders?

Generally, yes, as long as it is done for a "Valid Business Purpose" (like raising capital for a project) and not only to stop a vote.

Conclusion: The Mandate of Strategic Alliance

The White Squire is the definitive "Strategic Anchor" of corporate governance. It proves that in the struggle for control, independence is best preserved through a network of trusted allies. By establishing a rigorous framework of minority investments, standstill agreements, and voting blocks, the board can neutralize a hostile raider without the "Total Surrender" of a merger. Ultimately, the White Squire ensures that a company can navigate the pressures of the capital markets while maintaining its long-term vision—proving that in the end, the most powerful defense is a shareholder base built on a foundation of verifiable and technical loyalty.

Bilingual Summary: White squires buy minority stakes to block takeovers. 白衣护卫（White Squire）是指在公司面临敌意收购时，受邀购入公司大量少数股权（通常为 15%-25%）的友好投资者。与“白衣骑士”不同，护卫并不寻求全面控制公司，而是通过签署“不扩持协议”（Standstill Agreement）并承诺支持现任董事会，在表决权上形成一个令收购方无法逾越的“技术堡垒”。这种策略允许目标公司在保留独立地位的同时，利用外部资金和表决权支持来瓦解敌意收购者的算盘。
