NEW YORK--()--Two Sigma announced today that John Overdeck and David Siegel, Co-Chairmen and Co-Founders of the firm, will step down as Co-Chief Executive Officers and appoint Carter Lyons, Two Sigma’s Chief Business Officer, and Scott Hoffman, former Chief Administrative Officer and General Counsel of Lazard, as Co-Chief Executive Officers, effective September 30, 2024. David and John will step away from their day-to-day management roles, but continue lending their deep quantitative investment and technology expertise as Co-Chairmen to ensure that the company remains at the forefront of financial sciences.

Two Sigma was founded in 2001 by David Siegel, a computer scientist, and John Overdeck, a mathematician, with a focus on bringing technology and data science to investment management. Today, the firm manages around $60 billion in assets and employs approximately 2,000 people globally, two-thirds of whom are in research and development roles.

“Our vision has always been to build a sustainable organization driven by a systematic investment process, a commitment to investing in our people and platform, and an evolution mindset. With their vast experience, complementary expertise, and appreciation for Two Sigma’s unique culture, Carter and Scott will carry this vision forward, guiding the firm to even greater heights,” said David Siegel, Co-Founder and Co-Chairman. He added: “In light of the ongoing advancements in AI, I am more excited than ever about our ability to use our scientific investment philosophy to generate differentiated returns, and I look forward to continuing to be part of this journey for years to come.”

John Overdeck, Co-Founder and Co-Chairman said: “Two Sigma remains at the forefront of groundbreaking research, leveraging advanced technologies and techniques, while attracting the brightest minds across mathematics, science, computer science, and many other disciplines. We deeply value the talented individuals who comprise Two Sigma, as they relentlessly push the boundaries of innovation on behalf of our investors. We are very grateful for the trust our investors have placed in us over our first 23 years and have full confidence in Carter, Scott, and our strong and deep leadership bench as they guide the firm forward.”

Carter Lyons, Chief Business Officer of Two Sigma, has had a 25-year career in investment management and financial services, and has been instrumental in the company’s expansion and diversification during his 13 years at the firm. In this role, he collaborated closely with other company leaders to drive growth across the firm’s Investment Management and Private Investment businesses, including forging new relationships and deepening existing ones, delivering new products and solutions, and broadening the company’s global footprint. Carter joined Two Sigma in 2011 as Head of Investor Relations and was subsequently Co-Head of Two Sigma Advisers. Carter came to Two Sigma from BlackRock where he was Managing Director within the Global Client Group's U.S. and Canadian Institutional team.

Scott Hoffman served as the Chief Administrative Officer and General Counsel of Lazard, a preeminent global asset management and investment banking firm, until his retirement in September 2023 after a distinguished career at the firm that spanned nearly three decades. During his tenure at Lazard, Scott was instrumental in navigating complex governance changes and positioning the firm for long-term success and stability, which makes him uniquely well-suited for leadership as Two Sigma enters the next phase of its evolution. As Chief Administrative Officer and General Counsel, Scott assumed a broad range of responsibilities, including legal and compliance, internal policies, communications, information security, and internal audit. He worked closely with the firm’s leadership on client matters and as a counselor to Lazard’s board of directors, playing a critical role in M&A and the firm’s IPO on the New York Stock Exchange.

Carter Lyons said: “It has been extremely fulfilling to work alongside David and John over the past decade, developing innovative solutions for our clients and growing the company into the industry leader it is today. I’m excited for Scott to join the leadership team, and I have no doubt his deep experience and fresh perspectives will help Two Sigma to continue delivering attractive returns and creative solutions for years to come.”

“David and John have built a remarkable firm that has continuously broken new ground in investment management. I look forward to learning from them and partnering with Carter, as well as the entire Two Sigma team, to build on the firm’s progress and momentum,” said Scott Hoffman.

In connection with today's announcements, Ali-Milan Nekmouche, Chief Investment Officer of Equities, will take on the additional role of Chief Investment Officer for Two Sigma Investments, succeeding John in this role. Geoff Duncombe will continue to serve as Chief Investment Officer for Two Sigma Advisers and Chief Investment Officer of Macro. Carter and Scott, along with Jeff Wecker, the firm's Chief Technology Officer, and Tim Reynolds, the firm’s Chief Operating Officer, will partner with Ali and Geoff in driving forward the firm’s investment priorities and future growth. These leaders have collectively been responsible for driving cutting-edge research and technology initiatives, enforcing a strong scientific ethos, and embodying Two Sigma’s culture of innovation.
