For the first nine months of 1999, the company reported net income of $38.5 million (90 cents) and $918.1 million in revenue, compared with $35.7 million (83 cents) and revenue of $755.9 million in the first nine months of 1998.

Officials at the information technology consulting company attributed the gains to strength in all its markets, particularly a 40 percent rise during the quarter in its telecommunications business.

* CACI International, an Arlington-based information technology contractor, reported $3.8 million (34 cents a share) in earnings for the fiscal first quarter ended Sept. 30, a 22 percent gain over the $3.1 million (28 cents) earned in the same quarter a year ago.

* Columbia Energy Group reported a net loss of $9.7 million for the third quarter of 1999, compared with net income of $11.2 million (13 cents a share) for the same quarter a year earlier.

Without the two charges, Columbia Energy's net income would have been $9 million (11 cents), which was in line with expectations of analysts polled by First Call/Thomson Financial.

TNS's networks transmit credit-card and debit-card purchases from stores back to the financial institutions behind the plastic. The company also provides telephone-call billing validation and fraud-control services.

* American Mobile Satellite Corp. of Reston reported that its third-quarter losses grew mainly due to its purchase of XM Satellite Radio Inc. over the summer.

The company posted a $19 million loss in the quarter before subtracting interest, taxes, depreciation and amortization. In the same period last year, it lost $8.5 million before taking out those expenses.

American Mobile said the quarter's earnings also were hurt by a $12.1 million write-off related to the repayment of a credit facility.

Revenue in the quarter rose 5 percent, to $23 million, from $21.8 million. Service revenue for the quarter fell slightly to $17.3 million. But the number of service subscribers grew 29 percent, to 131,200 subscribers at the end of quarter, from 101,543 at the close of the same period in 1998.

American Mobile had owned a minority interest in XM Satellite Radio in the District until the summer, when it purchased the remaining interest in the technology company from World Space Inc. for about $129 million.

* NVR Inc., the McLean-based home builder, reported third-quarter net income of $30.3 million ($2.52 a share), up from $24.8 million ($1.87) in the third quarter of last year.

Although revenue from online tuition payments more than doubled over the year, to $1.1 million from $463,539, total revenue for the quarter declined to $3.07 million, compared with $4.3 million for the same period in 1998, following sale of the company's Ivy Software Inc. unit and several consulting businesses over the past year.

Consolidated net revenue declined in the quarter, falling to $12.3 million from $13.4 million in the period last year. The company said softness in sales both to new and existing customers contributed to that decline.

For the nine months that ended on Sept. 30, the company reported consolidated net income of $1.8 million (17 cents), compared with a loss of $2.1 million for the period in the previous year. Consolidated net revenue in the nine months declined 13 percent, to $39.6 million, from $45.7 million in the 1998 period.

* Chesapeake Corp. of Richmond, a specialty packaging and merchandising services company, yesterday reported net income of $65.8 million ($3.16 per share) for the quarter that ended Sept. 30, up roughly five-fold from the $13.2 million (61 cents) figure reported for the period a year earlier.

Most of the rise in income was due to a one-time $51.7 million ($2.48) after-tax gain, the net result from sales of the company's buildings products business and approximately 278,000 acres of timberland as well as an $11.7 million charge related to the closing of its kraft products business unit.

Without the gain, net income for the quarter would have been $14.1 million (68 cents), an 11 percent rise compared with the year-earlier period, the company said.

Net sales for the quarter were $350.2 million, up 34 percent from $260.7 million in the quarter the year before. The company attributed the rise primarily to its acquisition of the Field Group, a British-based packaging company, in March of this year.

Net income for the first three quarters of 1999 was $82.7 million ($3.87), up 83 percent from $45.1 million ($1.48) in the same nine months last year. Excluding the one-time gain, net income would have been $31.0 million ($1.45).

The company attributed the lower earnings to higher raw-material costs in its North American packaging operations and lower sales of jumbo rolls of tissue paper and lower prices for finished tissue products.

Net sales for the nine months, meanwhile, were $916.8 million, up 28 percent from $714.5 million in last year's period.

Revenue for the nine-month period rose 7.8 percent, to $1.96 billion, from $1.82 billion.

Lafarge, which supplies construction materials, said third-quarter results reflected growing sales of cement in the U.S. and eastern Canada, among other factors.
