Clay Brett

Clay has built a reputation as a preeminent advisor on M&A and private investment transactions by developing a dual skill set in financial analysis and legal practice. This allows him to balance market trends, business risk, capital asset pricing and legal analysis to produce comprehensive advice for his clients. Having spent years as both trusted counsel and a principal investor, Clay’s presence is a significant advantage for any client considering a strategic decision or fundamental business transaction.

At Baker Botts, Clay leads a broad transactional practice, representing private equity investors, private credit investors, portfolio companies and financial institutions in M&A, capital formation, financing and joint venture deals. While Clay has led transactions across sectors as a generalist, Clay is regarded as one of a handful of the most respected names in the private energy investment space.
