Asi Kirmayer

ASI KIRMAYER practices in all areas of corporate law with a focus on mergers and acquisitions, private equity, and joint ventures. He co-led Sidley’s New York M&A and Private Equity group between 2022 and 2025.

Asi has represented large multinational corporations, private equity funds, hedge funds, sovereign wealth funds, and other asset managers in domestic and international purchases and sales of both public and private companies. He has guided clients through leveraged buyouts, stock acquisitions, asset purchases, and joint ventures. His experience includes acquisitions and divestitures in both unregulated industries such as technology, auto parts manufacturing, and consulting, and highly regulated industries such as financial services (including banks, broker-dealers, insurance companies, and financial advisers), electricity transmission, downstream and mid-stream oil and gas, and professional services firms.    

A significant portion of Asi’s practice involves minority investments by financial and strategic investors. He has developed deep experience counseling clients through the unique issues arising in this area, including governance, determinations of “control” under applicable laws, and various exit considerations specific to minority investors. In addition, Asi has extensive experience with acquisitions and investments by foreign entities that are notified to the Committee on Foreign Investment in the United States (CFIUS) and the various transaction implications such notifications entail.

He prides himself in providing not simply technically sound legal advice, but also practical advice that adds commercial value to his clients. Asi works hand-in-hand with his clients who often consider him an integral part of their team because of his deep understanding of their business goals and approach to M&A.    

Asi received his LL.B. from the Faculty of Law at the University of Toronto in 1998 and his B.Sc. (First Class Honours) in computer science from the University of Calgary in 1995.
