Wachtell Lipton, X Corp. End $70M Twitter Deal Suit
-
X Corp. (Elon Musk’s social‑media company) has dropped its $90 million lawsuit against Wachtell, Lipton, Rosen & Katz.
-
The suit originally accused Wachtell of charging an “improper bonus” (or “success fee”) when it helped Twitter (now part of X) force Musk to complete his purchase of the company.
-
According to the complaint, the success fee wasn’t part of the original deal. Wachtell’s billing allegedly went from a standard hourly rate to a huge $90 million total fee near closing.
-
X Corp. filed in California state court, but a judge had previously pushed the dispute into private arbitration.
-
The dismissal is “with prejudice,” meaning X cannot refile the case.
-
No public explanation was given for why X dropped the lawsuit.
-
Wachtell defended its fee, saying the payment was approved by Twitter’s board and justified by its successful legal efforts.

Why It Matters
-
Law‑firm compensation scrutiny: Raises important questions about how big law firms negotiate “success fees” and whether those fees can be ethically or contractually problematic.
-
Corporate governance: Highlights the risk when dying or “lame‑duck” executives approve big payouts right before a major transaction.
-
Precedent for arbitration: Shows how disputes over legal fees in high-stakes mergers might go to private arbitration — not court.
-
Public perception: A high-profile case between Musk’s company and a top law firm raises eyebrows about fairness, business ethics, and legal privilege.
-
Risk management: For companies and boards: it’s a reminder to scrutinize fee arrangements and last‑minute contracts before major deals close.

Key Legal Outcomes
-
Case dismissed: X has ended its lawsuit against Wachtell with prejudice — no refile allowed.
-
Arbitration enforced: A judge ruled earlier that the dispute belonged in arbitration, which may have shaped how things resolved.
-
Fee challenged: The core issue was whether Wachtell’s “success fee” was proper given its prior hourly engagement.
-
Fiduciary duty claim: X alleged that Wachtell and Twitter’s former executives breached their fiduciary duties by approving a large, potentially unjustified bonus.
-
Contract validity: According to the original complaint, X argued that the “Closing Day Letter Agreement” modifying Wachtell’s fee might be invalid or unenforceable under California law.
