Activist That Encouraged Merger Only To Change Its Mind Denied “Extraordinary Remedy” Of A Deal Injunction

Key Takeaways

• Delaware court denied injunction, upheld merger protections.
• Fiduciary‑out clause deemed lawful despite activist objections.
• No topping bidder, so no irreparable harm shown.
• Activist’s reversal undermined claim of defensive transaction.
• Injunction risk outweighs benefit when shareholders approve deal.

Summary

The Delaware Court of Chancery rejected HoldCo’s request for an injunction to block Comerica’s merger with Fifth Third, finding the deal‑protection provisions lawful and not coercive. HoldCo, which had initially championed the transaction, could not demonstrate a colorable claim or irreparable harm, especially absent any topping bidder. The court emphasized that shareholders, having approved the deal with a premium, should retain the ability to decide without judicial interference. The ruling reinforces the high hurdle for M&A injunctions in Delaware.

Pulse Analysis

Activist investors often position themselves as catalysts for value‑creating deals, but the HoldCo v. Angulo case illustrates the limits of that strategy when a transaction already enjoys broad shareholder support. In this instance, HoldCo initially encouraged Comerica to pursue a sale to Fifth Third, only to reverse course and seek a court‑ordered stop. The Delaware Court of Chancery’s analysis focused on whether the merger’s protective clauses—such as the fiduciary‑out and termination fee—were illegal or oppressive. Citing precedent like Energy Partners and Omnicare, the court concluded that symmetric deal‑protection mechanisms do not strip a board of its fiduciary duties, especially when they preserve the ability to consider superior proposals.

The ruling also dissected the traditional three‑part test for a temporary restraining order: a colorable claim, a likelihood of irreparable harm, and favorable equities. HoldCo failed on all counts. Without a credible topping bidder, the court found no evidence that the deal protections deterred competing offers, rendering the alleged irreparable harm speculative at best. Moreover, the court questioned HoldCo’s defensive‑transaction argument, noting the activist’s prior endorsement of the merger and the fact that a majority of Comerica’s directors stood to lose their seats, further weakening the claim of coercion.

For the broader market, this decision sends a clear signal: Delaware courts will not intervene lightly in transactions that have passed the shareholder vote, even when activists later change their stance. The high evidentiary bar for injunctions preserves deal certainty, encouraging boards to negotiate robust protective clauses without fear of automatic judicial nullification. Activists, therefore, must build stronger, fact‑based arguments before attempting to derail approved mergers, reinforcing the principle that shareholder choice, not litigation, should drive M&A outcomes.
