WILDLIGHT, Fla. and SPOKANE, Wash., October 14, 2025 – Rayonier (NYSE: RYN) and PotlatchDeltic (Nasdaq: PCH) today announced that they have entered into a definitive agreement to combine in an all-stock merger of equals, creating a leading domestic land resources owner and top-tier lumber manufacturer.

Based on the closing stock prices of Rayonier and PotlatchDeltic on October 10, 2025, the last business day prior to the execution of the agreement, the combined company is expected to have a pro forma equity market capitalization of $7.1 billion and a total enterprise value of $8.2 billion, including $1.1 billion of net debt. Upon completion of the transaction, the combined company will become the second-largest publicly traded timber and wood products company in North America and will be well-positioned to capitalize on an improving housing market as well as opportunities in higher-and-better-use (HBU) real estate and land-based / natural climate solutions.

Under the terms of the agreement, which has been unanimously approved by the Boards of Directors of both companies, PotlatchDeltic shareholders will receive 1.7339 common shares of Rayonier for each share of common stock of PotlatchDeltic. The exchange ratio represents an implied price of $44.11 per PotlatchDeltic share, and a premium of 8.25% to PotlatchDeltic’s closing stock price on October 10, 2025 (the last business day prior to execution of the agreement). Upon closing of the transaction, Rayonier shareholders will own approximately 54% and PotlatchDeltic shareholders will own approximately 46% of the combined company.

The combined company will operate under a new name, to be announced prior to closing.

The combination will bring together two leading land resources companies, leveraging significant timberland and real estate expertise as well as operational excellence in lumber manufacturing. Together, the combined company will have a productive and diverse timberland portfolio comprising approximately 4.2 million acres, including 3.2 million acres in the U.S. South and 931,000 acres in the U.S. Northwest. In addition, the company will operate seven wood products manufacturing facilities, including six lumber mills with total capacity of 1.2 billion board feet and one industrial plywood mill. The transaction will also combine two highly complementary and successful real estate businesses with a strong track record of rural HBU premium realizations and significant long-term upside from value-add real estate development projects in Arkansas, Florida, and Georgia. The combination is further expected to provide robust opportunities and an enhanced platform to drive growth in land-based and natural climate solutions.

Mark McHugh, President and Chief Executive Officer of Rayonier, said, “We are excited to announce this strategic merger of equals, combining two exceptional land resources companies to deliver enhanced value for our shareholders and other stakeholders. Rayonier and PotlatchDeltic share a commitment to sustainability and a legacy of excellence in delivering land resources to their highest and best use. We look forward to completing the transaction, and we are confident that the merger will generate meaningful value creation.”

Eric Cremers, President and Chief Executive Officer of PotlatchDeltic, said, “This merger is a watershed moment for both companies. Our complementary assets and shared vision will unlock opportunities to create significant strategic and financial benefits beyond what could be achieved by either company independently. We look forward to working together to ensure a seamless transition and to capitalize on exciting opportunities for optimization and growth.”

Rayonier and PotlatchDeltic: A Combination of Two Exceptional Land Resources Companies

The combination is expected to offer significant strategic and financial opportunities beyond what could be achieved by each company on a standalone basis, including through:

•

Complementary and Productive Timberland Portfolios. The combination will result in enhanced geographic diversity and scale with approximately 4.2 million acres across 11 states. More than three-quarters of the combined company’s timberland assets will be located in the U.S. South, largely concentrated in top-tier timber regions.

•

Highly Efficient Wood Products Manufacturing Operations. The combined company will be well-positioned to realize positive leverage to improved housing demand and lumber pricing with its efficient and productive manufacturing facilities. In addition, with greater flexibility around REIT asset and income test limitations, the combined company can build on PotlatchDeltic’s existing position as a top-10 U.S. lumber producer through strategic investments in its wood products manufacturing business.

•

Value Creation Opportunities in Real Estate. The combined company will have a greater ability to drive value creation and cash flow growth from real estate by leveraging its premier HBU platform along with its established, high-value real estate development projects at Wildlight, Heartwood, and Chenal Valley.

•

Robust Land-Based and Natural Climate Solutions Capabilities. The additional scale of the combined company will result in an enhanced platform to drive growth in land-based and natural climate solutions, with a focus on utility solar, carbon capture and storage, minerals, and voluntary carbon market opportunities.

•

Compelling Synergy Opportunities. The combined company expects to realize approximately $40 million of annual synergies, driven by a combination of corporate and operational overhead cost savings. Run-rate synergies are expected to be achieved within 24 months of closing the transaction.

•

Strong Pro Forma Balance Sheet. The combined company is expected to have a strong pro-forma balance sheet with estimated Net Debt to LTM Adjusted EBITDA of roughly 2.5x and Net Debt to Enterprise Value of less than 15% (in each case, based on amounts as of and for the periods ending June 30, 2025). The combined company will remain committed to maintaining investment grade credit ratings.

•

Sustainable Dividend with Long-Term Growth Potential. Both companies intend to maintain regular dividend payments through completion of the transaction. Post-closing, the combined company intends to pay a regular quarterly dividend that is in line with Rayonier’s current annual dividend of $1.09 per share (with such per share amount to be reduced to take into account the additional Rayonier shares that will be issued pursuant to the Rayonier Special Dividend described below). Longer term, the combined company will seek to grow its dividend as end markets improve and synergies are realized.

Leadership, Board Composition, and Headquarters

The executive leadership team of the combined company will comprise roughly equal representation of top talent from both Rayonier and PotlatchDeltic. Upon closing of the transaction, Mark McHugh, President and CEO of Rayonier, will continue to serve as President and CEO as well as a member of the Board of Directors of the combined company. In addition, Wayne Wasechek, currently CFO of PotlatchDeltic, will serve as CFO of the combined company; Rhett Rogers, currently SVP, Portfolio Management of Rayonier, will serve as EVP, Land Resources; and Ashlee Cribb, currently VP, Wood Products of PotlatchDeltic, will serve as EVP, Wood Products.

Eric Cremers, currently the President and CEO of PotlatchDeltic, will be the Executive Chair of the Board of Directors of the combined company for 24 months after closing. The Board of Directors of the combined company will be comprised of five existing Directors from Rayonier (including Mr. McHugh) and five existing Directors from PotlatchDeltic (including Mr. Cremers). Rayonier will designate the lead independent director for the combined company.

The corporate headquarters of the combined company will be located in Atlanta, Georgia with significant regional offices maintained in Spokane, WA and Wildlight, FL.

Timing and Approvals

The transaction is expected to close in late first quarter or early second quarter of 2026. The transaction is subject to the satisfaction of customary closing conditions, including receipt of required regulatory approvals and the approval of both Rayonier’s shareholders and PotlatchDeltic’s shareholders.

Rayonier Special Dividend

Rayonier announced today that its Board of Directors has declared a one-time special dividend of $1.40 per share, consisting of a combination of cash and Rayonier common shares (the “Rayonier Special Dividend”). The dividend is payable on December 12, 2025, to Rayonier shareholders of record on October 24, 2025. As previously announced, the Rayonier Special Dividend is intended to distribute the taxable gains arising from Rayonier’s sale of its New Zealand business.

The cash component of the Rayonier Special Dividend (other than cash paid in lieu of fractional shares) will not exceed 25% in the aggregate, with the balance payable in Rayonier common shares. Rayonier expects the dividend will be a taxable dividend, regardless of whether received in the form of cash or common shares.

Rayonier shareholders will be asked to make an election to receive the dividend all in cash or all in common shares. To the extent that more than 25% of cash is elected in the aggregate, the cash portion will be prorated among the shareholders electing to receive cash. Rayonier shareholders who elect to receive the dividend in cash will receive a cash payment of at least $0.35 per common share. Rayonier shareholders who do not make an election will receive the dividend 25% in cash and 75% in common shares. The number of Rayonier common shares issued as a result of the dividend will be calculated based on the volume weighted average trading prices of Rayonier’s common shares on the New York Stock Exchange on December 1, December 2, and December 3, 2025. The Rayonier Special Dividend will be paid to Rayonier shareholders on December 12, 2025, which will be prior to the closing of the merger.

Because the Rayonier Special Dividend is only being paid to Rayonier shareholders, the merger consideration that PotlatchDeltic shareholders will receive at the closing of the transaction will be adjusted to provide PotlatchDeltic shareholders with additional consideration of equivalent value to the Rayonier Special Dividend. Specifically, (1) the exchange ratio will be increased to reflect the percentage of additional Rayonier common shares issued in connection with the Rayonier Special Dividend, and (2) the merger consideration received by PotlatchDeltic shareholders will include a cash component to reflect the cash issued in connection with the Rayonier Special Dividend, with PotlatchDeltic shareholders receiving an amount in cash per share equal to the average cash per share paid by Rayonier in the Rayonier Special Dividend multiplied by the 1.7339 exchange ratio. It is expected that the adjusted exchange ratio and cash component to be paid to PotlatchDeltic shareholders as part of the merger consideration will be determined and announced promptly following the payment of the Rayonier Special Dividend on December 12, 2025.

For more information regarding the Rayonier Special Dividend, investors should review Rayonier’s press release in respect thereof, available in the Investor Relations section of the company’s website at www.rayonier.com.
