He led teams for more than three decades at Raytheon, both in corporate and various divisional and business unit finance roles, and was a key player in several strategic initiatives including the Raytheon Technologies merger and integration. O’Brien will report directly to Intelsat’s new CEO, David Wajsgras.

Michael DeMarco, currently Intelsat’s chief services officer will become the new chief commercial officer (CCO), responsible for all Intelsat commercial services offerings to include product management, sales activities, sales engineering, and pricing.

He was also responsible for the company’s digital transformation strategy and the delivery of the company’s end-to-end service portfolio.

Clay McConnell has been named the company’s senior vice president of Corporate Communications and Marketing.
