Published February 22, 2023 by Robyn Sidersky

Herndon-based government contractor ManTech International Corp. has named Michael D. Ruppert as its new vice president and chief financial officer, following the retirement of Judy Bjornaas.

The appointment was effective Tuesday. Bjornaas spent a dozen years at ManTech, which was acquired by The Carlyle Group Inc. last year, and contributed to its growth toward becoming a nearly $3 billion government services contractor with nearly 10,000 employees worldwide.

Ruppert will report to ManTech President and CEO Matt Tait. He will be responsible for the company’s financial, treasury and corporate development functions.

Most recently, Ruppert was executive vice president, CFO and treasurer for aerospace defense contractor Mercury Systems Inc.

“I am very excited to take on the CFO role at ManTech, a company that is a tech leader in the government space with its sophisticated technology solutions that transform the success of customers in the defense, intelligence and federal civilian sectors,” Rupert said in a statement.

Before he was at Mercury Systems, Ruppert was co-founder and managing partner of RSPartners LLC, a mergers and acquisitions firm focused on aerospace and defense. He was also a managing director at UBS Securities, leading the company’s defense and government IT efforts. He has also worked at Lehman Brothers and Lazard Freres. He has a bachelor’s degree in finance and an MBA from the University of Virginia.

ManTech provides technology solutions for U.S. defense, intelligence and federal civilian agencies.
