Attractive end-market outlook across our businesses
Our business segments operate in a diverse set of industries with unique attributes and market drivers.
The AMES business, comprising 45% of our revenue, serves broad consumer and homeowner categories in its home markets of United States, Canada, Australia, and the United Kingdom through multiple sales channels. We expect AMES to benefit from continued healthy consumer spending in these countries, each of which are expecting positive real GDP growth, relatively low levels of unemployment, and moderate inflation.
Both AMES and Clopay are expected to continue to benefit as the U.S. housing market recovers from its historic bottom. Residential repair and remodel activity, the largest single market for Clopay and a significant market for AMES, is expected to continue to grow in 2020, albeit at a slower rate than seen in 2019.
