AQR challenges $8.4bn Clearwater buyout in Delaware

AQR Capital Management filed an appraisal petition in Delaware’s Court of Chancery seeking a judicial determination of the value of Clearwater Analytics shares after the $8.4 billion take-private closed in June. The firm contends shareholders received $24.55 per share and that the deal price understated fair value. AQR reported holding roughly 3.3 million Clearwater shares, worth about $81.3 million at the deal price.

The buyout was announced in December 2025 and was led by private equity firms Permira and Warburg Pincus, with participation from Francisco Partners and Temasek. AQR, which manages about $242 billion in assets, accumulated most of its Clearwater position after the takeover announcement, buying the bulk of shares in the fourth quarter of 2025 and the first quarter of 2026. The petition asks the court to establish what a fair per-share valuation should have been at the time of the transaction.

In its filing AQR alleges the sale process and the final price were affected by conflicts of interest and other shortcomings that prevented the company from maximizing value for unaffiliated public shareholders. Clearwater previously described the process as comprehensive, saying the acquisition was approved by independent directors and by a majority of shareholders without an interest in the transaction and that the $24.55 consideration represented about a 47% premium to the company’s share price before reports of a potential sale.

Appraisal-arbitrage involves investors buying shares after an acquisition is announced and asking a court to decide whether the agreed takeover price represented fair value. If the court finds the stock was worth more than the deal price, successful petitioners can receive the difference plus applicable interest. Recent changes to Delaware corporate law have altered the framework for appraisal claims and deal litigation, and several alternative asset managers have used the appraisal process to challenge completed transactions.

Court records show AQR has pursued similar petitions in at least four other deals since last year, including Silver Lake’s $25 billion acquisition of Endeavor Group Holdings, 3G Capital’s $9.4 billion purchase of Skechers USA, and the $3.9 billion acquisition of Select Medical Holdings by a consortium led by Welsh Carson Anderson & Stowe.

AQR, Permira and Warburg Pincus declined to comment on the filing. Clearwater did not respond to requests for comment. The Delaware Court of Chancery will determine whether the $24.55 price reflected fair value for Clearwater shareholders or whether a higher valuation is warranted.
