Mark Koschik — senior portfolio manager for energy giant Exelon’s $43 billion investment portfolio — died unexpectedly Sunday, the company confirmed.
He was coaching his son’s football game when he suffered a fatal health incident, according to Exelon chief investment officer Doug Brown.
“He was a pillar of our team,” Brown told Institutional Investor by phone Monday. “Mark was a consummate investment professional and made an enormous contribution. Far more important than all that, he was a great person, husband, and father.”
Koschik was 47 years old and the father of three children.
He spent the final years of his working career at Exelon, which he joined in December 2010, his LinkedIn profile shows.
“We built the team from scratch a little over nine years ago, and Mark was one of four or five initial hires,” Brown said. “He had a number of different roles over his nearly nine years here, heading up our equities, hedge fund strategies, and asset allocation as well. He was a key architect of our private credit strategies.”
Koschik worked across the now-$43 billion portfolio and was by all accounts a passionate and admired investor.
Two Sigma managing director Carter Lyons knew Koschik as a longtime client. “Mark was one of our most sophisticated investors who constantly challenged us, but more importantly, Mark was a great guy who will be sorely missed throughout our industry,” Lyons wrote in an email.
According to Brown, Koschik remained focused on the impact of his work for Exelon’s many stakeholders, who rely on the investment team to safeguard their retirement savings and to fund the decommissioning of nuclear power plants. “We would meet with employees for education sessions on saving plans, and Mark was a part that,” Brown said. “He was doing what he loved and knew that the end result was taking care of people.”
Described as “unflappable and a perfect gentleman,” Koschik earned his MBA from the University of Chicago’s Booth School of Business and an undergraduate degree from the University of Miami, his LinkedIn shows.
Before joining Exelon, Koschik served as a research analyst for Mesirow Advanced Strategies and worked with fixed income clients at Credit Suisse Securities.
“This is a very tough day, a very sad day,” Brown said.
