Buffett’s confidence in troubled decade-old acquisition finally pays off

Warren Buffett has said he paid too much for Precision Castparts in 2016. Now its complex metal castings are in high demand.

(This is the Warren Buffett Watch newsletter, news and analysis on all things Warren Buffett and Berkshire Hathaway. You can sign up here to receive it every Friday evening in your inbox.)

Six years ago, when Berkshire Hathaway took an $11 billion write-down of its $37.2 billion 2016 acquisition of Precision Castparts, Warren Buffett wrote in his annual letter to shareholders he had paid “too much” for the company, which makes “complex metal components and products.”

While it was a “fine company – the best in its business,” he had been “simply too optimistic” about its profit potential, a “miscalculation … laid bare” by the enormous downturn for the aerospace industry, Precision Castparts’ largest customers, amid the Covid pandemic.

In a CNBC interview when the deal was first announced, Buffett admitted it was “a very high multiple for us to pay,” but told shareholders at the 2016 meeting he had great confidence in Mark Donegan, the company’s CEO, both then and now, and the company’s long-term profit outlook.

It’s taken longer than he planned, but Buffett’s purchase is now looking pretty good.

As Reuters puts it, there is currently a shortage of the “complex” products Precision Castparts makes that are essential for engine turbine blades.

They’re also used in natural gas turbines, which are in demand to produce energy for artificial intelligence data centers.

This week, GE Aerospace announced it would pay $11.75 billion to acquire Consolidated Precision Products, one of the few companies that competes against Precision Castparts.

Barron’s calls that “pricey” at 26 times projected 2027 earnings before interest, taxes, depreciation, and amortization.

Using the same multiple, Barron’s estimates Precision Castparts is worth around $100 billion. That’s well above the potential value of $60 billion to $75 billion it cited in an article last month that said the unit “probably has become one of the more valuable divisions” of Berkshire.

It’s also nearly three times the 2016 purchase price.

In the Barron’s piece, Andrew Bary said Berkshire, and its share price, aren’t “getting much credit” for the subsidiary’s rising value, in part because CEO Greg Abel, like Buffett, doesn’t do analyst conference calls or investor events that could draw attention to the unit’s performance.

His recommendation: “Without Warren Buffett at the helm, Berkshire may have to start telling its story if it wants to attract a new generation of investors. This year’s trading action suggests that something may need to change.”

Berkshire bounces a bit as Wall Street sells off

Berkshire Hathaway shares managed a modest gain this week even as Wall Street’s major averages declined, a small departure from the 2026 “trading action” Bary cites.

Both the Class A and Class B shares gained almost 0.9% while the S&P 500 fell by 0.8%.

Until Friday’s bounce, that benchmark index, along with the Dow Industrials and the Nasdaq Composite, had dropped four days in a row as oil and bond yields moved higher.

Even with this week’s outperformance, Berkshire’s B shares still trail the S&P 500 by more than 10 percentage points so far this year.

Nebraska candidate moves to replace ad that included Buffett’s image

The campaign team for the Republican running in Nebraska’s 2nd Congressional District accelerated the deployment of a new campaign ad after Susie Buffett complained about a previous commercial that briefly included an image of her father, Warren Buffett.

In the ad, a picture of Buffett and his name appear on screen for roughly two seconds as candidate Brinker Harding says, “Here in Omaha, we know a thing or two about the stock market, some more than others. But we do it without insider information.”

He then goes on to highlight his call for a ban on Congressional stock trading, saying some lawmakers “trade on secrets you’ll never know,” as they “get rich” while “we barely get by.”

In a report that led its 10 PM CT newscast Wednesday evening, ABC affiliate KETV in Omaha reported Susie Buffett had asked Harding on Sept. 2 to remove the ad.

She told the station, “I think it’s worth it to say that Warren did not give Brinker his permission to use his face or name in his ad.

“It implies that my dad endorses him. He did not have permission to use it.”

The KETV report quoted Harding as saying in a statement, “In Nebraska, we work hard and support each other, and we do it honestly. Warren Buffett exemplifies that, and that was the point of my ad.”

The report said Harding did not comment on whether the ad would be taken down but noted “it does look like new ads from his campaign are beginning to run on some stations.”

A Harding campaign spokesperson told me the campaign did not think its ad implied a Buffett endorsement, but to be respectful to the Buffett family, it responded to her concern by accelerating the rollout of its next planned ad by several days, although its effort was hampered by the Labor Day weekend.

The commercial now running does not show or mention Buffett.

HIGHLIGHTS FROM CNBC’S BUFFETT ARCHIVE

The effects of 9/11 on Berkshire and the insurance industry (2002)

Warren Buffett shares his thoughts on the 9/11 attacks and explains how Berkshire’s insurance companies have started taking terrorism into account when writing policies.

AUDIENCE MEMBER: I know you lost a lot of money as a result of 9/11. But I would like to know how 9/11 changed your life and your investment strategy?

WARREN BUFFETT: It made everybody, I think, in the country aware, I mean, we’ve gone through world wars and all of that, and essentially felt quite protected within these borders.

And I have been quite worried about — Charlie can attest to — you know, the possibility, particularly of some kind of nuclear device in this country, by — probably more likely by terrorists than by some, at least, declared act of war by another state.

And 9/11 made everybody realize that as humans have not progressed, particularly, in terms of how they behave with each other over the years, they have progressed enormously in their ability to inflict damage on those they hate for one reason or another…

In terms of the business aspects of it, in your question, obviously the area at Berkshire that it effects most significantly, by miles, is insurance.

And prior to 9/11, even though we recognized that there could be huge monetary damages that flowed from the activities of what I would call deranged people, we hadn’t really written the contracts in such a way as to either get paid for taking that risk or to exclude the risk. In other words, we were throwing it in for nothing.

We had excluded risk for war. I mean, we knew that we’d seen what had happened in England in the 40s, and so we had taken account of something that some of us had seen with our own eyes, but we didn’t take account of something that we knew was possible, but we just hadn’t seen. And that’s, you know, that’s the human condition, to some degree.

Since September 11th, everybody in the insurance business recognizes that they had exposures that they weren’t charging for, and they either had to exclude those exposures or they had to charge for them.

We have written — first thing we had to do, of course, is we had lots of policies on the books that left us exposed to this, and most of those policies ran for a year, starting at different points. Those have run off to a great degree, but they’re not entirely run off.

The other thing we did was on new policies. We have sold a fair amount, quite a large amount, of terrorism insurance that excludes what we call NCB, nuclear, chemical, and biological, as well as fire following nuclear.

And, we can take a fair amount of exposure to that sort of terrorism, because it doesn’t — it won’t aggregate. It aggregated at the Twin Towers in a way that — World Trade Center — in a way that just about was as extreme as you could get for non-NCB-type activities.

I mean, that was a huge amount of damage done without nuclear, chemical, or biological.

But we can have tens of billions of dollars with NCB excluded throughout a greater New York area, or something, but we can’t have hundreds of billions of exposure that would be exposed, say, to, nuclear activities, because there an act or two, or three, coordinated, could cause damage that would destroy the insurance industry.

And if we had coverage on that, it would destroy us as well.

CoreWeave credit default swaps hit distress levels as investors sour on AI debt

Signs of distressed deepened in CoreWeave on Thursday.

CoreWeave’s credit stress continued to spiral on Thursday amid a broader sell-off in AI-related names.

CoreWeave — a so-called neocloud company — has taken on more than $51 billion of debt and obligations to finance its AI infrastructure build-out. It’s now facing a rebellion from stock and bond investors as concerns mount about AI overspending and debt levels.

Yields on CoreWeave debt have continued to climb, with the yield to maturity on its 9.75% bond due in 2031 reaching 15.78%. Bond yields move inversely to prices. Meanwhile, the spread on its five-year credit default swaps, which are insurance against default, at one point soared above 1,140 basis points. It last stood at nearly 1,038 bps — a 16% week-over-week jump and 164% higher than a year ago.

Credit concerns are spreading into AI equities too. CoreWeave’s stock dropped during trading Thursday before recovering and closing 5.94% higher. The moved followed Wednesday’s 15.5% nosedive.

Other neocloud stocks were under similar pressure. Nebius also sank before climbing higher to close 1.29% and and Iren ultimately ended the day down less than 1%.

Anxiety about AI overspending is also spreading. For instance, shares of Micron Technology and Advanced Micro Devices sold off following a big sell-off in South Korean chip stocks. Micron closed up 1.87%, while AMD fell 1.5%.

While AI debt worries have been rising steadily, investors have suddenly grown skittish about the underlying finances of companies borrowing heavily to buy chips, build data centers, and rent out computing power.

Coreweave’s credit default swaps are one place to see that stress.

Credit default swaps are contracts where buyers pay for protection in case the borrower can’t repay its debt. The spread widening in CoreWeave’s CDS means investors view the debt as riskier.

The market is “basically saying ‘no mas’ to AI debt without operating cash flow support,” the Evercore ISI trading desk said.

A spread level of 1,000 basis points or above is generally a sign of credit distress, said Gavan Nolan, executive director of fixed income pricing at S&P Global Market Intelligence.

No one is questioning whether demand for CoreWeave’s services is real, since the company has contracts with all the big hyperscalers, Nolan said. The question is whether the cash flows will ultimately arrive.

“It’s obviously heavily negative free cash flow at the moment, and it needs that cash flow to arrive really to justify all the capex that it’s spending,” Nolan said.

‘Self-fulfilling prophecy’

CEO Mike Intrator dismissed the market moves on Wednesday, according to a memo obtained by CNBC.

“When you are building a new type of technology company there will be periods of time when the market misunderstands and acts irrationally,” he wrote. “We are confident in our backlog which more than supports all of our debt obligations.”

The backlog is over $100 billion, with around two-thirds of it with investment-grade counterparts including Microsoft, Meta, IBM and Caterpillar, Deutsche Bank said in a note Thursday. The firm reiterated its buy-rating on the stock Wednesday, calling the dislocation a buying opportunity.

“The problem is this kind of concern can prove to be a self-fulfilling prophecy, and risks triggering broader issues in other AI-related names,” said Jim Reid, global head of macro and thematic research.

Domino effects may already be happening. Oracle’s five-year CDS spread also spiked this week. It was last at 282 basis points, a roughly 10% increase in one week.

“A downgrade from its BBB rating would risk pressuring IG-only investors into forced sales,” Reid said.

Netflix Chief Content Officer Bela Bajaria is leaving, will be replaced by Peter Rice

Netflix announced Bela Bajaria will be replaced by former Disney exec Peter Rice as the company’s chief content officer.

Netflix on Thursday announced Bela Bajaria will be replaced as the company’s chief content officer by former Disney exec Peter Rice, effective Oct. 26.

Rice most recently oversaw Disney’s cable channels, news programming and coverage of major sporting events.

“Peter is one of the most effective at-scale operators in the entertainment industry,” co-CEO Ted Sarandos said in a statement. “I’m excited to welcome him to Netflix as Chief Content Officer as we continue to scale and deliver members more of the stories they love.”

Before Rice was at Disney, he held roles 21st Century Fox and Fox Searchlight Pictures. Netflix in its announcement called him “one of the entertainment industry’s most respected creative executives.” In his new role, Rice will oversee the company’s global content organization, including scripted and unscripted series, film and live events.

″[Netflix has] shown again and again that they’re willing to take chances on distinctive voices and fresh ideas, and I’m excited to work with the team to help bring even more great stories to members everywhere,” he said in a statement.

Bajaria, who is leaving Netflix after nearly 10 years, most recently worked as the company’s global content team. She had been focused on the company’s live sports strategy, looking to create events out of buzzy games and tournaments.

“I’m incredibly grateful for everything she’s done to help Netflix entertain the world,” Sarandos said in a statement.

The announcement comes a day after Netflix instituted layoffs across its organization, eliminating approximately 6% of its workforce, or roughly 1,000 jobs.

The media company will report its next quarterly earnings on Tuesday.
