My Notes

• value - Trading at 0.7x P/S and 6.9x EV/EBITDA with 7.3% FCF yield indicates deep value orientation.
• Mortgage rates are critical demand drivers, with 100bps rate increases historically reducing housing starts by 15-25% over 12-18 months…
• Watch on earnings: Eurozone housing starts and building permits (monthly data), leading indicator for 6-9 month forward demand, TTF natural gas futures prices (€/MWh), primary cost input affecting 15-20% of COGS with quarterly contract reset exposure, European Central Bank deposit rate and Eurozone mortgage rate spreads, driving housing affordability and construction financing costs.
