McLaren Racing CEO Zak Brown sent a formal letter to FIA President Mohammed Ben Sulayem in the third week of May calling for immediate restrictions on multi-team ownership, three weeks after Mercedes appeared on a preliminary list of bidders for Alpine's Enstone operations. The letter, confirmed by two paddock sources, marks the first time a team principal has invoked governance procedure to force the ownership question onto the World Motor Sport Council agenda. Brown declined comment through a McLaren spokesperson. The FIA has not responded publicly.
The timing is mechanical, not emotional. Mercedes owns 33% of McLaren Applied, the team's technology licensing arm spun out in 2021. Toto Wolff's outfit holds board observation rights at Aston Martin through a 20% stake acquired before Lawrence Stroll's 2018 takeover. Red Bull operates two teams under a single parent—RB and Oracle Red Bull Racing—grandfathered under rules written when Dietrich Mateschitz bought Minardi in 2005. None of this violated existing regulations, which contain no multi-team ownership language. Brown's letter argues that silence is no longer tenable. Two people familiar with the document say it references NFL cross-ownership prohibitions and cites concerns about "competitive manipulation and sponsor conflict."
The structural issue is valuation arbitrage. Liberty Media's $17.1bn enterprise value for Formula 1 rests on the premise of ten independent franchises competing for constructor prize money, team sponsorship, and separate equity events. Audi's $656m entry fee for the 2026 Sauber takeover priced that independence. If Mercedes acquires even a minority Renault position—Alpine runs Renault power units and shares Viry-Châtillon engine development—sponsor contracts face immediate renegotiation risk. A McLaren commercial partner paying $42m annually for exclusivity in financial services cannot easily coexist with a Mercedes-affiliated rival carrying a competing bank logo. The contracts were written assuming arm's-length competition. The governance gap is that no document defines "arm's-length."
Three team principals contacted for this article declined on-record comment but confirmed the debate has moved from hospitality-unit conversation to lawyer review. One noted that Red Bull's dual-team structure survived precisely because it predated the 2021 Concorde Agreement, which governs revenue distribution through 2030. That agreement contains a clause requiring "unanimous team consent" for governance changes affecting ownership. Mercedes, Red Bull, and Ferrari hold de facto veto power. Brown's letter is a procedural end-run: by elevating the matter to the FIA—which oversees sporting regulations independent of Liberty's commercial rights—he forces a vote in a forum where teams hold less leverage. The FIA can amend the International Sporting Code without Concorde unanimity if it cites "sporting integrity."
The sponsor arithmetic is already moving. Two activation executives at rival teams said McLaren's BAT and Google deals, signed in 2022 and 2023, contain clauses triggering partial rebates if a Mercedes-affiliated competitor signs a tobacco-adjacent or cloud-infrastructure rival. Those clauses were negotiated when Alpine was Renault-owned and operationally separate. If Toto Wolff sits on an Alpine board—even in a non-executive capacity—the contracts treat it as a Mercedes asset for conflict purposes. One executive estimated the rebate exposure at $18m across McLaren's portfolio if Mercedes closes a Renault stake above 15%. BAT declined to comment on contract specifics.
The IPO subtext is louder. Liberty Media has telegraphed a Formula 1 tracking stock or spinoff by 2027, per March earnings-call language. That transaction requires clean team ownership lines for SEC disclosure. If Mercedes holds Aston Martin equity, McLaren Applied stakes, and Renault board seats simultaneously, Liberty's S-1 filing must either disclose the conflict or force divestitures before the roadshow. Two investment bankers familiar with sports-league IPOs said the NFL and NBA analogs required full cross-holding teardowns 18 months before listing. Formula 1 has no such timeline yet, but the Brown letter creates a documentary trail that complicates any claim of "unexpected" governance issues in a future prospectus.
Watch the June 7-9 World Motor Sport Council meeting in Paris, where Brown's letter will appear on the agenda if the FIA accepts it as a formal rules proposal. Mercedes has until June 4 to submit a counter-filing. Separately, Renault CEO Luca de Meo is expected to brief analysts on Alpine's "strategic options" during a June 12 earnings call, per a May 16 investor notice. If he announces a minority sale without naming the buyer, the paddock will parse which team principals attend the post-earnings cocktail reception at Renault's Boulogne-Billancourt headquarters.
The quiet part is now the fiduciary part: ten teams competed for $1.157bn in constructor prize money in 2024, per Liberty disclosures. If that number gets split among fewer economic owners, the math breaks for everyone not holding multiple chairs.
The takeaway
McLaren's governance attack on multi-team stakes forces Liberty's IPO timeline into collision with Mercedes' expansion strategy—and nobody has veto-proof votes.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
Built by the craft floor — apparel, media, packaging, and secure print.
This trade runs on hands, not desks. Imprint manufacturing & Komori Press · Canon high-speed secure-media operations is a craft floor — genuine Six Sigma discipline applied to ink, thread, foil, and registration, where a hundredth of an inch is the difference between a brand that reads serious and one that reads cheap. POPS4 is built by exactly those operators: independent, boots-on-the-ground engineers who carry their own book, read a client in microseconds, and put their name on every run. Beyond our own Virginia Beach floor, we work with a vetted network of craft manufacturers across the US — each meeting the highest excellence in QC standards in the industry, each a specialist in its own discipline — so apparel, hard-goods imprinting, media manufacturing, packaging, and secure printing all go to the bench built for them, coordinated from one accountable hub.
