Bethesda-based Lockheed Martin and Marriott International have made Fortune's list of top Blue-Ribbon companies for 2013, placing 24th and 25th, respectively, out of 36.
To qualify for the Blue Ribbon list, a company must appear on at least four Fortune lists in one calendar year. Lockheed and Marriott appeared on four Fortune lists last year, including the Fortune 500 and CNNMoney's Top MBA Employers.
According to the Maryland Department of Business and Economic Development, Lockheed Martin has 7,500 employees in the state, and Marriott, just under 10,000.
