“Thor’s top line sales performance continues to be strong in both our RV and bus businesses, pulled by solid retail RV activity through the spring and an improving bus market,” said Peter B. Orthwein, Thor Chairman, CEO & President. “However, our businesses were impacted by an elevated promotional environment driven by aggressive competition. This is resulting in the compression of our margins,” he added.
