Shamir Optical Industry and Essilor International continue to refuse any comments on a possible acquisition of the Israeli high-tech firm by the French giant, but it seems that there have been discussions. Shamir has reported a 16.3 percent increase in revenues to $41.0 million in for the second quarter ended June 30. The gross profit margin rose by 1.8 percentage points to 55.6 percent. Operating income for the Israeli company jumped by 58.1 percent to $6.4 million, while net income increased by 12.6 percent to $4.3 million. Excluding exceptional charges, operating income was up by 45.8 percent to $7.0 million. As of June 30, Shamir had cash and cash equivalents of $34.0 million. The company singled out its performance in the U.S. as particularly good, and attributed it to an effort to increase points of distribution there.
