Thor’s management team recently developed a three-year strategic plan focused on growth and margin improvement

The Strategic Plan was developed using a bottoms-up approach involving each of the Company’s operating subsidiaries and management teams

Key elements of growth include product innovation and capacity expansion – targeting mid- to high-single-digit growth

Key elements of margin expansion include improved product quality, value added content and features, and volume leverage – targeting 200 basis points of gross margin improvement over the planning horizon
