Berkshire Hathaway’s Financials

Berkshire posted total revenue of $245.5 billion in its 2020 fiscal year (FY), which ended December 31, 2020. Total revenue fell 3.6% during the year amid the adverse economic impacts of the COVID-19 pandemic. The company noted that the crisis has adversely affected nearly all of its operations, but to varying degrees. Revenue and earnings from most of the company's manufacturing and its service and retailing businesses declined considerably in the second quarter, but several of these businesses improved significantly in the third and fourth quarters.

Net earnings fell 47.1% compared to 2019, for total net earnings of $43.3 billion in 2020. The significant decline was mostly driven by earnings declines across most of Berkshire's business segments, which were partially offset by a $40.7 billion gain before taxes and non-controlling interests in the company's large equity portfolio.

As of changes made to GAAP in 2018, the company is required to include unrealized gains and losses arising from changes in its investment portfolio in its reported earnings. This accounting change contributes to earnings being significantly more volatile than they otherwise would be.
