Since 2016, the Plan has been updated through various amendments, including the most recent amendments adopted in 2024 and 2025, as outlined below. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;The Plan is administered by the GHC Savings Plan Committee, or the Plan Administrator, whose members are appointed by the Plan Sponsor. Vanguard Fiduciary Trust Company, or VFTC, serves as the Plan&#x2019;s trustee and recordkeeper. Effective January 1, 2021, the Plan entered into a Master Trust Agreement with VFTC to establish the Graham Holdings Company Master Trust, or the Master Trust. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;During 2025 and 2024, the Plan Administrator adopted amendments to the Plan, which are not expected to affect the Plan&#x2019;s qualified status under ERISA. A number of these amendments became effective in 2024. The Plan was restated in 2024, and the Summary Plan Description was amended effective January 1, 2025, July 1, 2025, and January 1, 2026. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:3pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;Effective January 1, 2025, the Plan was amended to implement the following changes:&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:3pt;padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%;padding-left:14.5pt"&gt;Updated for 2025 regulatory limits, changes to the Plan&#x2019;s one eligibility year of service affecting highly compensated employees, designating short-term disability pay as eligible compensation in certain situations, and how account balances between $1,000 and $7,000 and greater than $7,000 can be automatically distributed;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:3pt;padding-left:36pt;text-indent:-18pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%;padding-left:14.5pt"&gt;Allow certain small account balances of terminated participants to be automatically rolled over into an IRA with a third-party vendor, Portability Services Network ("PSN").

The total pre-tax and Roth combined contributions, however, is subject to dollar limitations set forth by the Internal Revenue Code ($23,500 in 2025). Participants age 50 or older by the end of the plan year, may make additional pre-tax or Roth 401(k) contributions (of up to $7,500 in 2025) that are called &#x201c;catch-up&#x201d; contributions.

Interest rates on loans are based on the prime rate as received by Vanguard from Reuters. Reuters calculates their prime rate through a formula, which includes the average lending rates of the top 30 banks in the United States. General purpose loans have a maximum term of 5 years and principal residence loans have a maximum term of 10 years. A participant may borrow as much as 50% of his or her vested account balance, subject to certain minimum and maximum limitations as defined in the Plan. The minimum loan amount is $1,000 with a maximum of $50,000. Loan processing fees are paid by the participant. As a result of a plan merger or rollovers received, there may be additional participant loans transferred to the Plan and administered in accordance with their terms.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:110%"&gt;Vesting&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;Upon enrollment in the Plan, participants are fully vested at all times in all amounts held in their accounts.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:110%"&gt;Transfers (to) from other Company plans &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;From time to time, participant accounts are reviewed and transferred into the Company plan that the participant is currently participating in. Additionally, transfers may also occur between the Plan and other Company plans that relate to individuals that move from a Highly Compensated Employee to a Non-Highly Compensated Employee position and vice-versa.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:110%"&gt;Plan Expenses&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;Certain costs of administering the Plan are generally paid by the Company and are therefore not reflected in the Plan&#x2019;s financial statements. Any expenses that are not paid by the Company are paid by the Plan itself. The Plan charges certain expenses directly to each of the participants&#x2019; accounts such as recordkeeping and maintenance of the website and phone services to participants. Each of the investment funds incurs investment and administrative expenses that are paid by the fund itself, which reduce the net investment return to participants.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:110%"&gt;Payment of Benefits&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;Participants may withdraw their vested account balance in accordance with the Plan document, which provides different rules for hardships, disability and withdrawals based on whether or not the participant has reached age 59 1/2. Upon termination of employment with the Company (including termination due to death, disability, or &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;retirement), participants may receive a lump-sum payment of their entire account balance, net of any outstanding loan balances. Otherwise, distributions generally begin on a participant's required beginning date, which is set by Federal law, and not by the Company. Participants may roll over account balances to individual retirement accounts or another employer&#x2019;s qualified retirement plan. If a terminated participant with an account balance dies prior to receiving the full value of the account, the account balance will be paid to the participant&#x2019;s beneficiary or in the absence of an election pursuant to the Plan&#x2019;s provisions. Account balances of $7,000 (in 2025) or less may not be deferred and are subject to automatic rollover/automatic cash out.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:110%"&gt;Plan Termination&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;Although it has not expressed any intent to do so, the Company has the right under the Plan to terminate the Plan at any time by action of the Plan Sponsor and Board of Directors subject to the provisions of ERISA.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measure. The Master Trust&#x2019;s assessment of the significance of a particular input to fair value measurements requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;Financial assets held in the Master Trust and the valuation techniques for measuring fair value are as follows:&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:110%"&gt;Registered Investment Companies (Mutual Funds)&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;: Registered investment companies (mutual funds) are valued at their respective net asset values. The net asset values are typically determined by the fund at the close of regular trading. These funds are required to publish their daily net asset value (NAV) and to transact at that price. The mutual funds are considered actively traded.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:110%"&gt;Common/Collective Trusts&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;: Valued at the NAV of units of the collective trusts.  The NAV, as provided by the trustee, is used as a practical expedient to estimate fair value.  This practical expedient is not used when it is determined to be probable that the fund will sell the investment for an amount different than the reported NAV. Were the Plan to initiate a full redemption of the collective trusts, the investment adviser reserves the right to temporarily delay withdrawal from the trusts in order to ensure that securities liquidations will be carried out in an orderly business manner.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:110%"&gt;Common Stock&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;: The Graham Holdings Company common stock in the Graham Holdings Company Stock Fund and Berkshire Hathaway common stock in the Berkshire Hathaway Stock Fund are valued at their year-end market value closing price. &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:110%"&gt;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. Furthermore, while the Plan Sponsor 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.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span
