Parsons [PSN] on Tuesday posted higher third quarter earnings due to a tax benefit and sales were up on acquisitions in its Federal Solutions Segment and to a lesser degree on an increase in organic revenue.

Net income climbed 38 percent to $56.8 million, 57 cents earnings per share (EPS), from $41.2 million (52 cents EPS). Adjusted earnings were up a percent to $84 million (52 cents EPS), topping consensus estimates of 37 cents per share.

Sales increased 5 percent to a record $1 billion on growth in the Federal Solutions and Critical Infrastructure segments. Sales in Federal Solutions were higher largely due to acquisitions in the past year and a percent of organic growth while the Critical Infrastructure segment was slightly up on an increase in organic sales.

Bookings in the quarter were robust at $1.1 billion and total backlog stood at $8.3 billion, up 4 percent from $8 billion a year ago. Order activity was driven by awards in the Federal Solutions segment, which recorded the largest ever cyber contract in its history, the $590 million Combatant Commands Cyber Mission Support award.

The company also won five other contracts in the third quarter worth over $100 million.

Free cash flow was $161 million.
