We are investigating possible breaches of fiduciary duty and other violations of law by the board of directors of HollyFrontier Corporation (“HollyFrontier” or the “Company”) (NYSE: HFC) in connection with the Company’s proposed merger with Sinclair Oil Corporation and Sinclair Transportation Company (“Sinclair”).  Under the terms of the agreement, HollyFrontier will form a new parent company, named “HF Sinclair Corporation” (“HF Sinclair”), which will replace HollyFrontier as the public company trading on the NYSE.  At the closing, existing shares of HollyFrontier will automatically convert on a one-for-one basis into shares of common stock of HF Sinclair, and HF Sinclair will issue approximately 60.2million shares of common stock to Sinclair.  The transaction is valued at approximately $1.8 billion.

WeissLawLLP is investigating whether HollyFrontier’s board acted in the best interestof HollyFrontier’s public shareholders in agreeing to the proposed transaction,whether the board was fully informed as to the valuation of Sinclair, andwhether all information regarding the process undertaken by the board and thevaluation of the transaction will be fully and fairly disclosed to HollyFrontier’spublic shareholders.

 WeissLaw LLP has litigated hundreds of stockholder class and derivative actions for violations of corporate and fiduciary duties.  We have recovered over a billion dollars for defrauded clients and obtained important corporate governance relief in many of these cases.  If you have information or would like legal advice concerning possible corporate wrongdoing (including insider trading, waste of corporate assets, accounting fraud, or materially misleading information), consumer fraud (including false advertising, defective products, or other deceptive business practices), or anti-trust violations, please email us at stockinfo@weisslawllp.com
