Recent Developments

8

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

RV Expansion On June 3, Thor acquired the RV production facilities in Wakarusa, Indiana formerly

operated by Navistar to expand motorized production to meet current demand and to vertically integrate RV paint operations

Nearly one million square feet of production space and 35 paint booths on 150 acres

Final transition plans to be implemented when the seller exits, which is expected late this summer

Three-Year Strategic Plan

9

Consolidated sales for the third quarter of fiscal 2013 were $1.05 billion, up 13% from $926.5 million

in the third quarter last year, based on strength in recreational vehicle (RV) sales. Net income for the third quarter was $43.8 million, up 6% from $41.3 million in the prior-year third quarter. Diluted earnings per share (EPS) for the third quarter was $0.82, up 5% from $0.78 in the third quarter last year.

Included in net income and EPS for the third quarter of fiscal 2013 were non-cash goodwill and intangible asset impairment charges of approximately $11.5 million. This included a $4.7 million intangible asset impairment charge triggered by the expected sale of the net assets associated with Company’s ambulance product line, and a $6.8 million goodwill impairment charge relating to the bus segment reporting unit which historically included the ambulance product line. These charges reduced EPS by $0.15 for the quarter. Excluding these items, EPS would have been $0.97 for the quarter.

Total RV segment sales were $929.8 million, up 15% from $807.2 million in the third quarter last year. RV segment income before tax was $77.6 million, up 31% from $59.2 million in the prior-year period.

Towable RV sales were $742.5 million, up 9% from $680.5 million in the prior-year period. Income before tax was $62.5 million, up 22% from $51.1 million in the third quarter last year. Towable RV income before tax increased to 8.4% of revenues from 7.5% a year ago, as a result of increased volumes and specific actions taken to improve operating efficiencies.

Motorized RV sales were $187.3 million, up 48% from $126.7 million in the prior-year third quarter. Income before tax was $15.1 million, up 86% from $8.1 million last year. As a percent of revenues, motorized RV income before tax rose to 8.1% of revenues from 6.4% a year ago, driven by improved product mix, volumes and enhanced operating efficiencies.

Bus segment sales were $119.4 million, up slightly from $119.3 million in the third quarter last year. Income before tax was a loss of $7.7 million, compared to income of $2.8 million in the third quarter last year. Bus segment income before tax was unfavorably impacted by the non-cash impairment charges relating to goodwill and intangibles of approximately $11.5 million.
