Warner Bros. Discovery (WBD) Stock Slides to Three-Month Low Amid Merger Regulatory Hurdles

Key Takeaways

• Warner Bros. Discovery shares plunged to a three-month nadir at $26.24 on Friday, creating a 17% spread versus the $31 merger consideration
• Multiple state attorneys general are mobilizing to contest the Warner Bros.-Paramount combination citing competitive concerns
• European Union regulators have initiated an investigation under Foreign Subsidies Regulation focused on Gulf state financing
• Approximately $24 billion in equity capital from three Middle Eastern sovereign wealth funds — Saudi PIF, Qatar IA, and Abu Dhabi’s L’Imad — is backing the transaction
• The companies are working toward a September 30 completion deadline, with Paramount presenting remedies to state officials to circumvent litigation

Shares of Warner Bros. Discovery experienced a nearly 3% decline on Friday, settling at $26.24 — marking the stock’s weakest performance over the past quarter. By Tuesday’s trading session, the price had edged upward to $26.72, though it remains considerably beneath the negotiated merger price of $31 per share in cash consideration.

This differential — approximately 17% — represents an uncommonly substantial spread for merger arbitrage transactions, especially considering the anticipated closing timeline before the conclusion of the third quarter of 2026.

Roy Behren, who co-manages the $2.5 billion Merger mutual fund with exposure to WBD, described the shares as “extremely attractive.” Taking a cautious approach, he projects an October completion and calculates an annualized gain exceeding 30% based on present valuations.

Paramount has incorporated a financial mechanism to encourage expeditious closing. Should the transaction extend beyond September 30, WBD shareholders will receive a 25-cent-per-share ticking fee — followed by additional quarterly disbursements until completion.

State Attorneys General Preparing Legal Action

Friday’s market reaction stemmed from emerging reports indicating state attorneys general across multiple jurisdictions are preparing to mount a legal challenge against the merger. Their primary apprehension centers on Warner Bros. becoming part of Paramount’s portfolio, potentially creating excessive concentration in the entertainment sector.

Entertainment industry labor organizations have voiced similar apprehensions, with union members expressing anxiety regarding potential workforce reductions resulting from the consolidated company.

Paramount has reportedly taken proactive steps to address these concerns. According to Bloomberg’s reporting, the company has already submitted a package of proposed concessions to state attorneys general, including California’s chief legal officer Rob Bonta. Federal antitrust authorities are not anticipated to oppose the transaction.

The United Kingdom’s competition watchdog has also commenced its own examination of the proposed combination.

European Commission Examines Gulf State Financing Arrangements

Compounding the regulatory challenges domestically, European Union officials disclosed Wednesday that they have launched an inquiry into the transaction pursuant to the Foreign Subsidies Regulation (FSR). The preliminary assessment period concludes on July 14.

The investigation focuses specifically on the $24 billion equity commitment provided by three Gulf region sovereign investment vehicles: the Public Investment Fund of Saudi Arabia, Qatar Investment Authority, and L’Imad Holding Company from Abu Dhabi.

The FSR framework was established to prevent government-backed capital from creating unfair competitive advantages within EU markets. Should regulators identify problematic elements, they possess authority to initiate comprehensive investigations and mandate corrective measures from Paramount.

This development aligns with the EU’s recent FSR enforcement pattern — authorities recently launched an in-depth investigation into JD.com’s proposed acquisition of German retailer Ceconomy, and previously examined Abu Dhabi National Oil Company’s €11.7 billion purchase of Covestro, which ultimately received regulatory approval.

The transaction’s enormous magnitude — with an equity valuation approaching $80 billion — has contributed significantly to the elevated arbitrage spread. Merger arbitrage specialists operate with finite capital resources, and a deal of this scale strains available capacity.

Concurrently, Paramount’s shares have faced downward pressure, currently trading near $10 and declining 22% year-to-date. The stock hovers closer to its 52-week floor of $8.60 than its peak above $20, burdened by concerns surrounding debt levels and the premium paid to surpass Netflix’s competing offer.

The European Union’s preliminary review timeline extends through July 14.
