CACI International [CACI] on Wednesday reported strong fourth quarter financial results driven by reduced taxes, which boosted earnings, and higher sales.

Net income in the quarter increased 46 percent to $137 million, $5.74 earnings per share (EPS), versus $93.7 million ($3.68 EPS) a year ago, topping consensus estimates by 12 cents per share. Per share results were aided by a lower share count due to CACI’s stock repurchase program.

Operating income in the quarter declined due to higher expenses, a sales mix that trended toward lower margins, and tax benefits taken a year ago due to a government benefit package to help the private sector cope with the COVID-19 pandemic.

Sales increased 5 percent to $1.6 billion from $1.5 billion a year ago, with 4 percent of the gain organic.

For fiscal year 2021, net income increased 42 percent to $457.4 million ($18.30 EPS) from $321.5 million ($12.66 EPS) a year ago. Sales were up 6 percent to $6 billion from $5.7 billion, with 5 percent of the growth organic.

Orders in the quarter were a strong $3.6 billion and for the year $9.2 billion, leading to a 12 percent growth in backlog to $24.2 billion versus $21.6 billion a year ago. Free cash flow in the quarter was $77.7 million and for the year $537.1 million.

In fiscal year 2022, CACI expects sales to range between $6.2 billion and $6.4 billion and adjusted earnings to be between $18 and $18.83 EPS. Adjusted earnings for FY ’21 were $20.29 EPS. Free cash flow in FY ’22 is expected to be at least $720 million.
