What led to the 2020 impairment of Precision Castparts?
Berkshire Hathaway recorded an $11 billion write-down on Precision Castparts six years after the 2016 purchase. Buffett stated in his annual shareholder letter that the company had paid too much due to excessive optimism about long-term profitability. The aerospace sector, Precision Castparts' largest customer base, collapsed during the Covid-19 pandemic, exposing the miscalculation in earnings projections. The original deal valued the maker of complex metal parts at 37.2 billion dollars. Buffett had described the business as the best in its industry yet still flagged the high purchase multiple as a concern during the 2016 annual meeting. He noted the payment reflected a very high multiplier for Berkshire at the time of the deal announcement on CNBC, while expressing continued confidence in CEO Mark Donegan and the company's long-term prospects despite the later downturn that revealed the error in earnings estimates. The impairment came after Buffett wrote that he had shown simply excessive optimism regarding the profitable potential of the business. The huge downturn in aerospace revealed the misjudgment that had been made at the time of the acquisition. This acknowledgment highlighted how the pandemic exposed the gap between projected earnings and actual performance across the complex metal components produced for engine turbines.
How has demand changed for Precision Castparts products in 2026?
Shortages of specialized turbine blades and components have emerged across aerospace and power generation markets. Precision Castparts supplies parts used in jet engines and natural gas turbines. The latter category now sees rising orders tied to electricity needs for artificial intelligence data centers. Reuters reported current supply constraints for these complex products. This shift reverses the earlier pandemic-driven weakness and supports improved operating results for the Berkshire subsidiary. The products are described as complex metal parts and products essential for turbine blades in engines, with the natural gas turbines seeing particular demand growth linked to power requirements for AI infrastructure. The shortage of these complex products is now supporting stronger performance after the period of over-optimism and the subsequent impairment. Demand has returned strongly in both aerospace and the power sector, with the supply tightness directly tied to the recovery in engine production and the new power needs of data centers. The reversal from the 2020 downturn now positions the unit for sustained higher utilization of its manufacturing capacity.
What does the GE Aerospace deal reveal about current valuations?
GE Aerospace agreed to pay 11.75 billion dollars for Consolidated Precision Products, a direct competitor. Barron's calculated the price at 26 times projected 2027 earnings before interest, taxes, depreciation and amortization. Applying the same multiple to Precision Castparts produces an approximate value of 100 billion dollars. That figure exceeds the 60 to 75 billion dollar range cited in earlier analysis. The transaction highlights scarcity value for companies capable of manufacturing high-specification turbine components. Barron's described the GE move as expensive given the multiple paid, underscoring how limited supply of such specialized parts has lifted potential worth well above the original 2016 purchase price of 37.2 billion dollars. The same 26 times multiple applied to the Berkshire unit produces the higher estimate of around 100 billion dollars, well above previous internal valuations mentioned in recent coverage. This comparison shows how the market now prices scarcity in complex turbine parts far higher than the impaired book value from 2020.
Why has Berkshire Hathaway stock performance diverged from the broader market?
Berkshire Class A and Class B shares rose nearly 0.9 percent in a week when the S&P 500 fell 0.8 percent. The outperformance occurred despite four consecutive down days for major indices driven by higher oil prices and bond yields. Year-to-date, Berkshire Class B shares still trail the S&P 500 by more than 10 percentage points. Limited visibility into subsidiary performance, including the absence of executive conference calls, has been cited as a factor limiting investor recognition of the Precision Castparts turnaround. Andrew Bary noted in Barron's that neither Buffett nor CEO Greg Abel participates in analyst calls or investor events that could highlight the unit's growing contribution, suggesting Berkshire may need to improve storytelling to attract new investors as the subsidiary's value rises. The weekly gain came even as broader indices declined for four straight sessions on rising oil prices and bond yields, yet the year-to-date lag remains significant. The divergence reflects both short-term resilience and longer-term recognition challenges for the growing contribution of the Precision Castparts operations.
