The free cash flow conversion ratio was 53% versus 44% in 2019, buoyed by strong growth in Ebitda, a continuing low working capital requirement (WCR) and the decrease in maintenance capex. Operating WCR represented 17 days’ sales at December 31, 2021, representing a historic low for the second consecutive year (compared to 18 days at end-2020 and 27 days at end-2019), thanks to efforts to monitor overdue receivables and despite the first steps taken to rebuild inventories in order to best serve its customers. ROCE hit an all-time high of 15.3% (versus 11.1% in 2019), resulting in strong value creation for our shareholders, in both industry and merchanting. Investments in securities net of debt acquired totaled €1,352 million (€1,423 million in 2020), and related primarily to the acquisition of Chryso in the construction chemicals segment – but also Duraziv in Romania and Z Aditivos in Peru – the bolt-on acquisitions of Panofrance and Raboni Normandie in France; Brüggemann in modular construction in Germany; and a joint venture investment in Massfix, a glass recycling company, to develop the circular economy in Brazil. In total, acquisitions made by the Group in 2021 represent approximately €820 million in full-year sales and approximately €125 million in Ebitda.
