Susan H. Mac Cormac

Partner | San Francisco

Susan (“Suz”) co-chairs the ESG + Sustainability and Social Enterprise + Impact Investing practices. Her practice focuses on late-stage financings, secondaries, and other corporate transactions for investors, such as SoftBank and Temasek, and on investments for some of the top investors dedicated to impact, from “impact first” foundations to family offices to private equity funds. She co-led the drafting group for the first of the new corporate forms (the Social Purpose Corporation in California), has created hybrid/tandem corporate structures and crafted debt and equity instruments that blend impact with traditional financial terms, and has used corporate law to develop creative capital market solutions to pressing environmental problems. She also advises the boards of public and private companies on corporate governance and fiduciary duties as applied to sustainability and climate change.

She was named a California Lawyer Attorney of the Year (CLAY) in 2012 and 2016 by Daily Journal and the Most Innovative Lawyer in North America in 2015 by the Financial Times.

Leading Business Advisor

A powerhouse negotiator, clients note that “you cannot get a better corporate counsel” and that Suz “understands the big picture, could not be more responsive, and understands the business” (The Legal 500 US). She has extensive experience providing corporate and finance advice to companies and investors in connection with growth equity financings and secondaries, with particular experience in late-stage investments that have come to rival traditional strategic acquisitions in size and significance. Her experience includes leading some of the highest-profile late-stage investments over the past few years, including notable transactions for SoftBank Group (in the two largest private tender offers in history) in its $7.7 billion investment in Uber, $4.4 billion investment in WeWork, further $10 billion investment in WeWork, $1 billion investment in SoFi, and $250 million investment in Kabbage. She has also advised Temasek on its $800 million investment in Verily Life Sciences, Intel on its equity investment in Cloudera, and each of Fortress, TPG Rise, Vision Ridge Partners, Generation Investment Management, and Pontifax AgTech in numerous mid- to late-stage investments in clean technology, sustainability, education, food, and agriculture technology.

Social Enterprise and Impact Investing

Suz is the go-to legal resource for social enterprises (for-profit and non-profit companies focused on social or environmental purpose), impact investors (investors interested in social or environmental returns), and mainstream companies developing environmental, social, and corporate governance policies. With deep expertise in the impact investing model, institutional investors exploring the space turn to her for creative solutions and her ability to structure both investments and companies to emphasize impact and returns.
