Insights

Corporate governance and leadership analyst

Matador reshapes its finance leadership, promoting an internal executive to CFO.

Matador Resources appoints Robert T. Macalik as Executive Vice President and Chief Financial Officer effective September 29, 2025, while confirming that former CFO William D. Lambert’s departure from the role on September 24, 2025 is not tied to financial, accounting, or policy disagreements. This indicates a planned internal succession rather than a crisis-driven change.

Macalik has served in progressively senior finance roles since joining in 2015 and will also remain Chief Financial Officer of San Mateo Midstream, LLC, the company’s midstream joint venture. His employment agreement is based on a previously filed form used for other senior executives, suggesting consistent treatment of executive compensation and severance terms.

The company references prior proxy and 10‑Q disclosures instead of providing new compensation details here, so the key takeaway is the consolidation of financial leadership under a long-tenured internal executive. Future company filings may provide additional clarity on how this leadership structure influences financial strategy and reporting.
