Garret Harencak plans to step down as president of the prime contractor of the National Nuclear Security Administration’s Nevada National Security Site, people familiar with his plans said Tuesday.
In August, the board of directors of Mission Support and Test Services (MSTS), the site’s Honeywell-led prime, informed site employees that Harencak, a retired Air Force major general, would resign on Nov. 1, exactly two years after he joined the company from Jacobs to replace Mark Martinez as president of MSTS.
Roger Rocha, MSTS’ vice president and chief operating officer, has been the interim president since the announcement of Harencak’s planned retirement, but the succession picture at the site remained unclear as of Tuesday.
“The MSTS Board of Managers has not yet named a replacement for Garrett Harencak,” a spokesperson wrote in a Tuesday email to the Exchange Monitor.
MSTS’ contract, awarded in 2017, runs through 2027 and is worth about $5 billion.
In addition to Honeywell, MSTS includes Jacobs and Stoller Newport News Nuclear, part of Huntington Ingalls Industries.
Jacobs’ government contracting business was scheduled to merge Sept. 27 with Amentum, creating a publicly traded Amentum.
Editor’s note, Sept. 17, 2024, 8:27 p.m. Eastern time. The story was updated with more information about Harencak’s resignation, and to clarify that the MSTS board informed employees of his resignation.
