Calls upon the PHX Board of Directors to engage with WhiteHawk to pursue and complete a transaction

Encourages PHX stockholders to reach out to PHX's Board and ask them to engage with WhiteHawk around a value-maximizing transaction

WhiteHawk Energy, LLC (together with its subsidiaries, "WhiteHawk"), calls for a response from the Board of Directors of PHX Minerals, Inc. ("PHX" or the "Company") related to WhiteHawk's proposal to acquire PHX in a $4.00 per share all-cash transaction.

"We are asking all stockholders to reach out to PHX to encourage discussions with WhiteHawk related to WhiteHawk's all cash proposal of $4.00 per share. We have previously demonstrated financing for this transaction to PHX and its advisors," says Daniel C. Herz, WhiteHawk's Chief Executive Officer. "WhiteHawk's proposal benefits all stockholders and represents a substantial premium to PHX's recent trading prices."

WhiteHawk Energy strongly encourages all PHX stockholders to:

Reach out to PHX's Board: Express your concerns about their lack of engagement around our proposal and demand transparency regarding their plans to maximize stockholder value.
