HF Sinclair Corp has announced a substantial stock repurchase agreement, agreeing to buy back 2,350,000 shares of its common stock from REH Advisors Inc. for approximately $257 million. This agreement, dated October 29, 2026, is a key part of the company's ongoing efforts to enhance shareholder value and manage its capital effectively.

The purchase price of $109.37 per share will be funded using cash on hand, with the transaction expected to close around November 3, 2026. This repurchase is part of HF Sinclair's broader $1.5 billion share repurchase program, which was authorized by the company's Board of Directors on August 26, 2026.

HF Sinclair Corp, identified by the SIC code 4610, operates in the pipeline sector, specifically focusing on pipelines that do not transport natural gas. The company trades under the ticker symbol DINO on the New York Stock Exchange.

According to the filing, this stock repurchase marks the twenty-third privately negotiated transaction between HF Sinclair and REH Advisors. To date, HF Sinclair has repurchased $766 million in common stock under its share repurchase program, leaving approximately $734 million remaining for future buybacks.

Following this transaction, REH Advisors is expected to own less than the threshold required to designate a member to HF Sinclair's Board of Directors. Under the existing Stockholders Agreement, if REH's ownership falls below 5%, the designated board member must offer to resign within 30 days. The Board will then decide whether to accept or reject this resignation.

This strategic move not only reflects HF Sinclair's strong financial standing but also indicates the company's commitment to returning capital to shareholders. The repurchase program may be adjusted based on market conditions and other relevant factors, and the Board retains the discretion to discontinue it at any time.

As HF Sinclair continues to navigate the competitive landscape of the pipeline industry, this stock repurchase is expected to influence its capital structure and shareholder dynamics significantly. Future filings may provide additional insights into the company's ongoing strategies and financial health.
