William D. Lambert served as Executive Vice President and Chief Financial Officer of Matador Resources Company, an independent energy company engaged in the exploration, development, production, and acquisition of oil and natural gas resources, from 2018 until his retirement in 2023. Prior to his elevation to EVP, he joined Matador in 2012 as Vice President of Finance and advanced to CFO in 2013. In these roles, Lambert was instrumental in shaping the company's financial strategy, overseeing all aspects of financial planning, reporting, treasury management, investor relations, and capital markets activities during a period of significant growth and expansion in the Delaware Basin. Before joining Matador, Lambert held senior finance positions in the energy sector, including Vice President of Finance for Southwestern Energy Company's Fayetteville Shale operations, where he managed financial operations for one of the largest natural gas plays in the U.S. Earlier in his career, he spent over a decade at JPMorgan Chase in the energy investment banking group, advising on mergers, acquisitions, and financing for upstream oil and gas companies. His deep expertise in energy finance and capital markets proved invaluable to Matador's transformation from a smaller operator to a multi-billion-dollar enterprise. Under Lambert's leadership, Matador successfully executed multiple high-profile acquisitions, secured substantial debt and equity financings, and navigated volatile commodity markets while maintaining strong balance sheet discipline. His contributions were pivotal in the company's evolution, including the development of its flagship assets in the Wolf and Rustler breaks areas of the Delaware Basin, culminating in Matador's recognition as a top-tier operator. Lambert's strategic acumen and commitment to shareholder value left a lasting legacy at the company.
