EXPLANATORY NOTE

This report combines the annual reports on Form 10-K for the year ended December 31, 2025 of Rayonier Inc., a North Carolina corporation, and Rayonier, L.P., a Delaware limited partnership. Unless stated otherwise or the context otherwise requires, references to “Rayonier” or “the Company” mean Rayonier Inc. and references to the “Operating Partnership” mean Rayonier, L.P. References to “we,” “us,” and “our” mean collectively Rayonier Inc., the Operating Partnership and entities/subsidiaries owned or controlled by Rayonier Inc. and/or the Operating Partnership.

Rayonier Inc. elected to be taxed as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended, effective December 31, 2004. We operate as an umbrella partnership REIT (“UPREIT”), conducting substantially all business through the Operating Partnership. Rayonier Inc. is the sole general partner of the Operating Partnership. On May 8, 2020, Rayonier, L.P. acquired Pope Resources, a Delaware Limited Partnership (“Pope Resources”) and issued approximately 4.45 million operating partnership units (“OP Units” or “Redeemable Operating Partnership Units”) of Rayonier, L.P. as partial merger consideration. These OP Units are generally considered to be economic equivalents to Rayonier common shares and receive distributions equal to the dividends paid on Rayonier common shares.

As of December 31, 2025, the Company owneda 99.0% interest in the Operating Partnership, with the remaining 1.0% interest owned by limited partners of the Operating Partnership. As the sole general partner of the Operating Partnership, Rayonier Inc. has exclusive control of the day-to-day management of the Operating Partnership.

Rayonier Inc. and the Operating Partnership are operated as one business. The management of the Operating Partnership consists of the same members as the management of Rayonier Inc. As general partner with control of the Operating Partnership, Rayonier Inc. consolidates Rayonier, L.P. for financial reporting purposes, and has no material assets or liabilities other than its investment in the Operating Partnership.

We believe combining the annual reports of Rayonier Inc. and Rayonier, L.P. into this single report results in the following benefits:

•Strengthens investors’ understanding of Rayonier Inc. and the Operating Partnership by enabling them to view the business as a single operating unit in the same manner as management views and operates the business;

•Creates efficiencies for investors by reducing duplicative disclosures and providing a single comprehensive document; and

•Generates time and cost savings associated with the preparation of the reports when compared to preparing separate reports for each entity.

There are a few important differences between Rayonier Inc. and the Operating Partnership in the context of how Rayonier Inc. operates as a consolidated company. The Company itself does not conduct business, other than through acting as the general partner of the Operating Partnership and issuing equity or equity-related instruments from time-to-time. The Operating Partnership holds, directly or indirectly, substantially all of the Company’s assets. Likewise, all debt is incurred by the Operating Partnership or entities/subsidiaries owned or controlled by the Operating Partnership. The Operating Partnership conducts substantially all of the Company’s business and is structured as a partnership with no publicly traded equity.

To help investors understand the significant differences between the Company and the Operating Partnership, this report includes:

•Separate Consolidated Financial Statements for Rayonier Inc. and Rayonier, L.P.;

•A combined set of Notes to the Consolidated Financial Statements with separate discussions of per share and per unit information, noncontrolling interests and shareholders’ equity and partners’ capital, as applicable;

•A combined Management’s Discussion and Analysis of Financial Condition and Results of Operations, which includes specific information related to each reporting entity;

•A separate Part II, Item 9A. Controls and Procedures related to each reporting entity;

•A separate Part II, Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities section related to each reporting entity; and

•Separate Exhibit 31 and 32 certifications for each reporting entity within Part IV.
