 valuation methodologies used for assets measured at fair value:

| • |     | Berkshire Hathaway Class B stock fund: Class B shares of Berkshire Hathaway (Symbol BRK-B) are valued at the closing price as reported on the New York Stock Exchange. The fund also consists of temporary investments in the State Street Government Short Term Fund for liquidity purposes and is 
 therefore classified within Level 2 of the valuation hierarchy.                                                                                                                                                                                                                                     |

| • |     | Mutual funds: Valued at the net asset value (“NAV”) as reported on various stock exchanges and 
 classified within Level 1 of the valuation hierarchy.                                          |

| • |     | Self-directed brokerage accounts: Valued at the NAV of underlying funds as reported on various stock exchanges 
 and classified within Level 1 of the valuation hierarchy.                                                      |

| • |     | Common collective trust funds: Valued using the NAV provided by the administrator of the trust and classified                                                                                      
 within Level 2 of the valuation hierarchy. The NAV is based on the value of the underlying assets owned by the trust, minus its liabilities, and then divided by the number of shares outstanding. |

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. There have been no changes in the methodologies used from 2023 to 2024. Furthermore, while the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. The following tables set forth by level, within the fair value hierarchy, the investments of the Plan reported at fair value held by the Plan Trust as of December 31, 2024 and 2023 (in thousands):
