Digital Forestry sector. Pioneering Groundbreaking digital tool for the forestry Tetrys Numerous scenarios to define the best clone / environment match. 10B0e%nefits Risk Management Analytics / big data to anticipate and mitigate climate change risks. Reduced volatility in forest productivity. 2021 planting program: 2% gain on productivity (vs. 2020). Reduction in the average forest-to-mill distance. Producing more with less natural resources. 8

BioinformaticsClone Selection based on DNA Molecular Markers Milestone in Forestry Breeding! 300,000 trees are candidates for cloning Fast elimination of inadequate candidates Better selection of genetic materials for our long-term tree breeding program More precise selection of commercial clones 9
