Item 7.01. Regulation FD Disclosure.

As previously announced on November 4, 2025, Caterpillar Inc. (the "Company") realigned its organizational structure by moving its Rail division from the Power & Energy segment into the Resource Industries segment. The Company implemented this change effective January 1, 2026, to better reflect its organizational and operational structure and align with how our chief executive officer, who serves as the Company’s chief operating decision maker (CODM), assesses performance and allocates resources.

For informational purposes and to assist investors in making comparisons between historical and future financial information that will reflect the revised reporting segments, the Company has furnished selected historical, unaudited quarterly segment financial information reflecting this realignment. This information is furnished as Exhibit 99.1 to this Current Report on Form 8‑K and is also available on the Company’s investor relations website at http://investors.caterpillar.com.

Unaudited Historical Operating Segment Data

Exhibit 99.1 to this Current Report on Form 8-K reflects the impact of the Rail division realignment on the Company’s historical segment results on a continuing operations basis. The recast information also reflects certain segment reporting changes previously disclosed in the Company’s Form 10‑Q for the three and nine months ended September 30, 2025 and the 2025 Form 10-K, including transfers of specified responsibilities among segments.

•Responsibility for business strategy, product design, product management and development, manufacturing, marketing and sales, product support and sourcing of wear and maintenance components and related parts moved from All Other Segment to Resource Industries.

•Responsibility for business strategy, product design, product management and development, manufacturing and product support for electronics and control systems moved from Resource Industries to All Other Segment.

•Responsibility for research and development for autonomy and automation, electronics and software for machines and engines moved from Resource Industries to the All Other Segment.

The recast information remains subject to additional adjustments as the Company finalizes the new reporting structure related to the Rail division realignment. Investors are cautioned that this information is unaudited. The changes in reporting structure affect only the presentation of historical segment information and have no impact on the Company’s previously reported consolidated financial statements.

Certain updates made to previously communicated forward-looking statements made by the Company are furnished in Exhibit 99.2 to this Current Report on Form 10-K.

The information in this Current Report on Form 8-K, including Exhibit 99.1 and 99.2, should be read in conjunction with the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025, which was filed with the Securities and Exchange Commission on February 13, 2026.

The information contained in this Item 7.01 shall not be deemed filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the“Exchange Act”), or otherwise subject to the liabilities under that section and shall not be deemed incorporated by reference into any filing under the Exchange Act or the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such filing.
