On his 67th birthday, Brian Roberts finalized the plan to split the company his father built: NBCUniversal and Sky spin off, cable stands alone, and the 15-year bet on ‘convergence’ is officially over. John Malone’s one-word review: ‘finally.’

Comcast (CMCSA) will spin off NBCUniversal and Sky — Saturday Night Live, Sunday Night Football, Universal Pictures — into a stand-alone media company, leaving Comcast a broadband-and-connectivity pure play. It dismantles the convergence bet Roberts made when Comcast bought NBCUniversal 15 years ago, and it follows the same road Paramount and Warner already traveled: the content businesses that were supposed to feed the pipes became anchors on the multiple instead.
Cable titan John Malone — who says he teases Roberts about ‘woulda, coulda, shoulda’ — supports the split. The market has been asking for it for years; the family finally agreed.
The financial logic is multiple arbitrage: broadband cash flow trades at one valuation, declining-but-cash-rich media at another, and stapling them together meant the market priced the whole thing at the worse multiple. Separated, each can be owned — or avoided — on its own merits. Academic evidence has long favored spinoffs: focused managements, cleaner capital allocation, and the spun-off orphan often outperforms once forced sellers finish.
The income caveat: dividends get re-divided in a split, and the media side of these separations typically carries the weaker payout and the tougher secular story. Owning ‘Comcast’ today means owning two different futures by next year.
We treat conglomerate breakups as re-underwriting events: when a holding splits, each piece has to re-earn its seat in the book on its own cash flow, payout durability and balance sheet. History says keep the boring toll-road half (broadband) and be skeptical of the glamour half — the same instinct that runs the rest of the portfolio.
Breakups like this are why we underwrite cash flows, not tickers. When a conglomerate splits, we re-evaluate each piece as if it were a new position: the broadband utility half — recurring revenue, pricing power, infrastructure moat — is the kind of business an income book keeps; the media half has the weaker payout and the harder decade, and nostalgia isn’t a thesis. The broader lesson from Comcast, Paramount and Warner is the one we already run the book on: focus gets rewarded, empires get discounted.
