Allegheny Beverage Corp. yesterday reported a loss of $2.8 million (33 cents a share) for the quarter that ended June 27, compared with a loss of $2.7 million (31 cents) for the same quarter last year.

Allegheny has sold its furniture division, Desks & Furnishings Inc., and its laundry services subsidiary, Macke Laundry Services Inc. It has also signed an agreement to sell its food-service subsidiary, Service America Corp.

Because those businesses have been sold, the company said it considered them discontinued operations for accounting purposes. Its loss from continuing operations, which includes general administrative expenses, interest expenses and finance charges, was $5 million in the current quarter versus $3 million during the same quarter the previous year.

VSE Corp. reported quarterly income of $1.1 million (61 cents a share), a 7.5 percent increase over $979,000 (54 cents) for the same period in 1986. Revenue was $30.1 million, 15.3 percent higher than $26.1 million quarterly revenue for the same period last year.

Income for the first six months of the year was $1.4 million (78 cents), a 7.9 percent drop from $1.55 million (85 cents) for the first half of 1986, the company said. Revenue for the first half was $56.6 million, 15 percent higher than the $49.2 million for the same period in 1986.

VSE, located in Alexandria, is an engineering, development and management services firm.

The Rouse Co. of Columbia, Md., announced second-quarter earnings of $1.4 million (1 cent a share), down 76 percent from the $5.6 million (10 cents) a year ago. Second-quarter revenue was $87.5 million, up 31 percent from $74.5 million last year.

A Rouse spokesman attributed the lower second-quarter earnings this year to a 1986 sale of a shopping center in Pittsburgh, which he said artificially boosted 1986 earnings.

For the first half of 1987, earnings were $7.1 million, a drop of 20.3 percent from $8.9 million for the first half of 1986. Revenue was $178.99 million, an increase of 19.8 percent over $149.4 million for the first six months of last year
