Olin Corp. reported Winchester’s sales for the fourth quarter 2018 were $145.5 million compared to $165.4 million in the fourth quarter 2017.

The decrease of 12 percent was primarily due to lower shipments to commercial customers.

Fourth quarter 2018 segment earnings for Winchester were $4.3 million compared to $11.1 million in the fourth quarter 2017.
