Not companies so much as job. And Virginia has been successful in attracting such employers as Amazon, Microsoft, and Nestle.

*Montgomery County failed to capture its pre-2007 share of regional job growth, leading to a cumulative impact of more than 14,000 high quality jobs in key industry sectors that chose to locate elsewhere in the region.
*From the 1st quarter of 2016 through the 3rd quarter of 2020 (most recent data available), Fairfax County gained more jobs and gained jobs at a faster rate than Montgomery County in the research and development in the physical, engineering, and life sciences industry.
*Montgomery County actually lost private business establishments from 2007 to 2019, while in the rest of Maryland the number of private establishments increased by 6.9%. During that period, private establishments in Fairfax County increased by 12.5%, in the District of Columbia private establishments increased by 21.6%, and in Arlington County private establishments increased by 21.9%.
*Montgomery County’s neighbors are offering large incentives to employers on the move and to spur development. For example, Virginia offered Microsoft $22.5 million to move 1,500 jobs to Reston ($15,000 per job). This is well above the recent Montgomery County/State of Maryland combined award of approximately $11,700 per job. Given that businesses in Maryland must also overcome significant structural disadvantages (e.g., local piggyback income tax, higher corporate taxes, etc.), these awards are well below the level that would be necessary to incentivize a business to choose a Montgomery County location rather than a comparable location in Northern Virginia.
