4 2021 results and outlook for 2022 Financial results SAINT-GOBAIN UNIVERSAL REGISTRATION DOCUMENT 2021 124 In line with the third quarter, and as expected, there was a modest rise in volumes, up 0.6% over the second half given the very high comparison basis in 2020, when trade professionals in Europe had taken less holiday during the summer and over the Christmas and New Year period owing to the coronavirus pandemic. Compared to second-half 2019, volumes were up by 4.9%, with an acceleration between the third and fourth quarters (up 3.6% and 6.0%, respectively) in all Group segments. On a reported basis, sales came in at a record high of €44,160 million, with a negative currency effect of 0.4% over the year, but a positive effect of 1.7% in the second half, due mainly to the appreciation of the British pound, the Nordic krona and the US dollar in the fourth quarter alone. The Group structure impact reduced sales by 2.2% over the year and by 3.6% in the second half, reflecting the ongoing optimization of the Group’s profile, with €5.6 billion in total sales divested or signed to date since the launch of the transformation at the end of 2018. In 2021 alone, Saint-Gobain completed or signed 20 divestments representing €2.0 billion in sales, including mainly Lapeyre in France, Distribution in the Netherlands and Spain, specialized Distribution in the UK, Glassolutions in Germany and Denmark, and Pipe in China. During the year the Group completed or signed 37 acquisitions representing almost €2.0 billion in sales, including mainly Chryso and GCP Applied Technologies (GCP) – reinforcing its existing positions to make it a major global player in construction chemicals with more than €4 billion in sales – and Panofrance, a specialist distributor of timber and panels. The integration of Chryso is progressing particularly well and the company is consolidated in the Group’s financial statements as from fourth-quarter 2021, with objectives set at the date of the acquisition exceeded in 2021 in terms of both sales (€431 million, up 26% like-for-like on 2019) and Ebitda (€87 million). Continental Building Products (plasterboard in the US), acquired in February 2020, created value in the second year – one year earlier than targeted – thanks to a strong operating performance and a rapid and seamless integration: sales totaled USD 605 million in 2021, with Ebitda at USD 185 million, representing an Ebitda margin of 30.6%, and synergies exceeded initial expectations, at an annualized rate of USD 50 million. Note that in light of the hyperinflationary environment in Argentina, this country which represents less than 1% of the Group’s consolidated sales is excluded from the like-for-like analysis. 2018-2021 Impact of the successful operational and financial transformation Portfolio optimization Outperformance versus the markets 2021 Continued outperformance Positive price-cost spread of €60m Additional cost savings of €150m in businesses impacted by the coronavirus par le coronavirus 2018 Launch of transformation 2021 10.2% 7.7% €3,207m €4,507m +250 bps Double-digit margin ambition delivered Operating income rose sharply, reaching a new all-time high of €4,507 million, a rise of 58% on a reported basis versus 2020 and of 33% versus 2019.
