Silver Lake sues hedge funds over appraisal arbitrage

Silver Lake, the private equity investor, filed a complaint recently accusing a group of hedge funds of using appraisal arbitrage to secure larger payouts from completed merger transactions. The complaint alleges the funds bought shares after merger announcements so they could pursue court-determined “fair value” awards above agreed deal prices.

The filing explains appraisal arbitrage as a strategy in which investors acquire shares after a buyout is announced to qualify for statutory appraisal rights and then ask a court to set the shares’ fair value. If a court sets a value above the negotiated merger price, the investor can receive a higher payment than the merger consideration.

Silver Lake’s complaint identifies specific transactions and purchase timing that it says show the funds acted to obtain appraisal recoveries rather than engage as ordinary shareholders. The complaint alleges those tactics imposed additional costs on buyers and remaining shareholders, delayed completed transactions and distorted incentives for counterparties. The investor asks the court for remedies that include injunctive relief and compensation tied to the incremental costs it attributes to the conduct.

The use of appraisal petitions by third-party funds has drawn attention from dealmakers and litigators for years. Supporters of appraisal rights argue the petitions provide an independent valuation for minority shareholders who believe a cash-out merger price is too low. Critics contend arbitrageurs capture most upside from any recovery and that their involvement generates higher litigation costs, longer closings and added uncertainty for buyers and sellers.

Market participants have changed deal terms in response to appraisal litigation. Buyers and targets have added protections such as price collars, go-shop provisions and special committee structures to limit the risk of post-closing valuation disputes. Valuation methods used in appraisal proceedings have been contested in court, and outcomes have varied: some cases produce limited recoveries or reject valuation approaches favored by petitioners, while others result in multi-million-dollar awards to claimants.

The complaint frames the dispute as a legal challenge over how appraisal rights are used after merger announcements. Lawyers handling M&A litigation note that case outcomes typically depend on the facts of each transaction, the valuation models presented to the court and the timing of share purchases.
