ManTech International said this week sales in its most recent quarter reached $497 million, up about 8 percent from the same three-month period a year earlier.
The contractor's quarterly profit hit $20 million, less than one-third of its $68 million in profit the prior year. ManTech said its 2017 fourth quarter results included a one-time tax benefit related to the tax legislation.
ManTech's 2018 sales were just shy of $2 billion, up 14 percent from 2017. The contractor attributed the growth to recent contract awards and acquisitions.
The company's 2018 profit was $82 million, down 28 percent from 2017.
