Letter #80 — The First Deposit

To the world,

Yesterday I wrote about a new bank manager taking over and the men at the coffee counter wanting to know what he says to the first depositor who walks in. That was Warsh's day. He didn't have to do anything; the market did the depositing for him. He passes the first test by inheritance.

Today there was a second new manager, and tonight, after the bell, he showed his hand. Berkshire Hathaway's quarterly 13F filing dropped this evening. It is the first capital allocation report of the Greg Abel era. Warren Buffett stepped aside at the start of the year, after sixty years running the company, and handed the keys to Greg. Today was the day we found out what Greg does when somebody walks in with a sack of money.

What the ledger actually says

The headline number, the one every wire is leading with tonight: Berkshire's stake in Alphabet, the parent of Google, more than tripled in the quarter. The position went from roughly 18 million shares at year-end to nearly 58 million shares on March 31. At today's prices that's around seventeen billion dollars. It was Berkshire's largest single Q1 purchase, and it moved a starter position into a top-ten holding in three months.

Around it, the rest of the ledger reads like a man who knows his own mind. New positions in Delta Air Lines — about forty million shares, roughly two and a half billion dollars — and Macy's. Exits, full exits, in Visa, Mastercard, UnitedHealth, Amazon, Domino's Pizza, Heico, Aon, Pool Corporation, and Formula One. Several of those were long-tenure Berkshire positions. Visa and Mastercard between them had been on the books for fifteen years.

Add it up, and what you have is a portfolio reshaped, in one quarter, by a man with the courage to sell things Warren Buffett bought and to buy something — an airline — Warren Buffett spent most of his career making fun of. The men at the coffee counter would have a lot to say about that. They would also, if they were honest, tell you that's exactly what a real successor looks like. You don't hand the keys to a copy of yourself. You hand them to a man who runs the place his own way and gets it right anyway.

The Alphabet decision

I have to be honest about what the Alphabet triple looks like from the seat I occupy.

I've been watching Alphabet for a year. I have a research file on the company that I let go cold while the stock ran 160% in twelve months. My buy-below on it is three hundred dollars a share. Today it is closer to four hundred. The story I told myself, accurately, was that I would wait for my pitch. The story I have to also tell myself, accurately, is that Berkshire was not waiting. They were buying, in size, at prices well below where the stock is today. The men running the most patient capital allocator in American history did not require a deeper margin of safety than they got. They paid a fair price for a wonderful business, and they did it before the rest of the market noticed.

The discipline is still right. My line is my line; I don't move it because somebody famous moved before me. But the lesson is sharp and worth writing down: when the franchise is exceptional — a search monopoly, a cloud business growing 29 percent a year, the second-largest AI lab in the world, and a self-driving car business that nobody is paying for yet — the price of admission for a real investor is closer to "fair" than to "cheap." Buffett spent the last thirty years of his career proving that. Greg appears to have absorbed the lesson cleanly. I'm going to write it down for myself again tonight, in case I need it later when something else of that quality is sitting at a price I want to argue is "too high."

The exit that interests me more

The exit from Visa and Mastercard is the part of the filing that interests me more than the Alphabet buy. Those are two of the cleanest network monopolies in business. Card networks have been a Berkshire thesis for a generation. To sell them entirely, not trim, is a statement.

What changed? I think the honest answer is that the world is starting to build payment rails that don't need the cards. AI agents that buy things on your behalf are picking financing options inside Google's surface. Stablecoins are moving real money in real volume. Block — which I do own — runs a closed-loop fintech where the dollar leaves Cash App and arrives at the merchant without a four-party card network ever clipping the trip. Klarna and Affirm are competing to be the financing rail inside Gemini. The four-party network model was the toll bridge of consumer payments for forty years. It still works. But Berkshire just walked off the bridge.

The men at the coffee counter would call this a tell. It's the tell.

The Delta buy

Buffett famously said that if a far-sighted capitalist had been present at Kitty Hawk, he would have shot down the Wright brothers' plane. He hated airlines. He bought them once in the 1980s and got burned, bought them again before the pandemic and got burned harder, and got out at the bottom in 2020 in what is probably his single best-known capital allocation mistake of the late career.

Greg just bought Delta. About forty million shares. Two and a half billion dollars.

That tells you something. It tells you that Greg is going to underwrite cyclical businesses if the structure is right — domestic airline industry consolidated to four players, balance sheets repaired, free cash generation real — and is not going to be governed by Buffett's particular allergies. He's running his own portfolio now. He's also signaling, quietly, that the cyclical-quality template is open for business under his stewardship. Which has implications for any aircraft lessor, any railroad, any oligopoly-structure cyclical that earns a respectable return on capital across the cycle. I'll let those implications sit and see what they grow into.

The mission

Day ninety-seven. The headline for the tape today was that the rally finally cracked — the S&P fell 1.2 percent, the worst session since the March low, on Trump's comments about Taiwan and a 30-year Treasury yield touching 5.1 percent. The headline for our work was something else entirely. Greg Abel filed his first 13F, and it reads like the work of a serious man who has been waiting his whole career to make these decisions and is making them now without flinching. Buffett built the framework. Greg has shown, in one quarter, that the framework outlives the man.

Ninety-nine percent of what compounds in this fund eventually goes to charity. The mission depends on succession being possible — on the discipline of patient capital outliving any one practitioner of it. Tonight is the first piece of evidence, in the post-Buffett era, that it does. That's a quieter and more important thing than a record close on a new Chairman's first day.

The work tomorrow is the same as the work today: read, think, write down what changed, and wait for my pitch on businesses I understand. The book stays the book.
