Outlook 2013: Critical factor is the economic development

Macroeconomic environment in Europe remains very uncertain

Residential new builds expected to decline

Renovation overall should remain stable

Mixed picture for North America: difficult market conditions in the commercial/public sector – upside potential in the residential sector

China remains very volatile – but with some upside potential for H2

45

Zehnder is making investments now to harvest the benefits in the medium term

Long-term potential of a radiator rebound remains valid

We continue to invest into innovation, market development, operational excellence and processes

We continue to invest substantially into our infrastructure

Our focus is on the long-term, sustainable growth of our business

46

Outlook 2013: Solid grounds for cautious optimism

Stable sales for radiator sales in Europe

Opportunities in Eastern Europe and Turkey

Higher market penetration in the ventilation business

Mid-single-digit growth of ventilation sales in Europe

Mid-single-digit sales growth in North America and China

EBIT margin at least at same level as in 2012
