William Zartler, a founder and managing director at Denham Capital, has left the firm after more than eight years leading the energy infrastructure operations.
Zartler is no longer listed on Denham’s web site, but a cached version of the site listed him as a founder and managing director. He was also a member of the executive committee along with Stuart Porter, Carl Tricoli, Scott Mackin and Riaz Siddiqi. Porter is chairman and chief executive officer at Denham.
It’s not clear why Zartler left the firm. A person with knowledge of the situation said Zartler’s departure will not trigger a key-man provision in any of the funds. Denham declined to comment.
Zartler did not return a request for comment. His LinkedIn profile shows him as a private investor with Solaris Energy Capital since February 2013. It’s not clear if Solaris Energy Capital is a new firm.
Another high-level executive, managing director for strategy and development Joseph Casey, also is no longer listed on Denham’s web site. The firm declined to comment about Casey’s status. His LinkedIn profile still shows him working at Denham.
Denham closed its sixth private equity fund last year on $3 billion on its hard-cap. Denham Commodities Partners Fund VI had an about 90 percent re-up rate from the prior vehicle, the firm said at the time. Late last year, Denham announced it would open an office in Perth, Australia this year to pursue opportunities in the metals and minerals sector.
