Whittaker’s first-quarter net dropped about 61%.

The plunge in net income, to about $5.7 million from $14.9 million in the previous year, reflected the full impact of closing out Los Angeles-based Whittaker Corp.’s huge hospital operation in Saudi Arabia, President Joseph F. Alibrandi told Dow Jones news service. He said Whittaker expects to receive about $30 million in final payments from the Saudis “in the next couple of months.” Revenue fell to about $276.4 million from $349.8 million a year ago, while revenue in the life-sciences division plummeted to $103 million from $193 million.
