Nicholas Fund, Inc. (the “Fund”) is organized as a Maryland corporation and is registered as an open-end, diversified management investment company under the Investment Company Act of 1940, as amended. The primary objective of the Fund is long-term growth. The following is a summary of the significant accounting policies of the Fund:

In accordance with Accounting Standards Codification (“ASC”) 820-10, “Fair Value Measurement” (“ASC 820-10”), fair value is defined as the price that the Fund would receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market of the investment. ASC 820-10 established a three-tier hierarchy to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in

pricing the asset or liability, including assumptions about risk, for example, the risk inherent in a particular valuation technique used to measure fair value such as a pricing model and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad levels listed below.

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used as of April 30, 2026 in valuing the Fund’s investments carried at value:

The Fund did not hold any Level 3 investments during the period.

The amount of distributions from net investment income and net realized capital gain are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP for financial reporting purposes. Financial reporting records are adjusted for permanent book-to-tax differences to reflect tax character.

The tax character of distributions paid during the six months ended April 30, 2026 and the years ended October 31, 2025 and March 31, 2025, was as follows:

The following information for the Fund is presented on an income tax basis as of October 31, 2025.

April 30, 2026. At April 30, 2026, the fiscal years 2022 through 2025 remain open to examination in the Fund’s major tax jurisdictions.

The Fund has an agreement with Nicholas Company, Inc. (with whom certain officers and directors of the Fund are affiliated) (the “Adviser”) to serve as investment adviser and manager. Under the terms of the agreement, a monthly fee is paid to the Adviser based on an annualized fee of 0.75% of the average net asset value up to and including $50 million and 0.65% of the average net asset value in excess of $50 million.

The Adviser may be paid for accounting and administration services rendered by its personnel, subject to the following guidelines: (i) up to five basis points, on an annual basis, of the average net asset value of the Fund up to and including $2 billion and up to three basis points, on an annual basis, of the average net asset value of the Fund greater than $2 billion, based on the average net asset value of the Fund as determined by valuations made at the close of each business day of each month, and (ii) where the preceding calculation results in an annual payment of less than $50,000, the Adviser, in its discretion, may charge the Fund up to $50,000 for such services.

- 12 -

A director of the Adviser is affiliated with a law firm that provides services to the Fund. The Fund incurred expenses of $8,489 for the period ended April 30, 2026 for legal services rendered by this law firm.

For the period ended April 30, 2026, the cost of purchases and the proceeds from sales of investment securities, other than short-term obligations, aggregated $353,660,478 and $574,851,562, respectively.

The Fund has adopted FASB Accounting Standards Update 2023-07, Segment Reporting (“Topic 280”) - Improvements to Reportable Segment Disclosures. An operating segment is defined in Topic 280 as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the public entity’s chief operating decision maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. The management committee of the Fund’s adviser acts as the Fund’s CODM. The Fund represents a single operating segment, as the CODM monitors the operating results of the Fund as a whole and the Fund’s long-term strategic asset allocation is pre-determined in accordance with the terms of its prospectus, based on a defined investment strategy which is executed by the Fund’s portfolio managers. The financial information in the form of the Fund’s portfolio investments, total returns, expense ratios and changes in net assets (i.e., changes in net assets resulting from operations, subscriptions and redemptions), which are used by the CODM to assess the segment’s performance versus the Fund’s comparative benchmarks and to make resource allocation decisions for the Fund’s single segment, is consistent with that presented within the Fund’s financial statements. Segment assets are reflected on the accompanying statement of assets and liabilities as “total assets” and significant segment expenses are listed on the accompanying statement of operations.
