Chairman and CEO Walter C. Johnsen said, “After a strong performance in the first half of 2024, sales of first aid products in the U.S. were soft in the third quarter due to customer timing and market conditions. Sales of our Westcott cutting tools and DMT sharpeners continued to be strong in the quarter, with increased placement in large mass market accounts.”

“During the quarter, we introduced the latest generation of industrial first aid kits with patented automatic replenishment capabilities. The use and expiration of components in the kits are now monitored in real time, allowing the customer to order replacements automatically.

First aid units with these capabilities facilitate compliance with OSHA, ANSI, and other regulations.”

Excluding Camillus and Cuda, net sales for the third quarter of 2024 increased 3% compared to the third quarter of 2023.

Excluding Camillus and Cuda, net sales for the nine months increased 5% compared to the same period in 2023. The sales increase for the nine-month period was due to market share gains across multiple product lines.
