Comparing the change over a 10-year period, production has decreased and revenue has increased:
UPM revenue 2024: 10.3 billion (2014: 9.9)
Products 2024: 10.1 Mt + 1.7 Mm3 (2014: 13 Mt + 2.1 Mm3)

If one disregards those tonnes and cubic meters and instead looks at their relative figures, revenue has increased by 33% in ten years. However, inflation has eroded 26% of that (EUR Inflation Calculator - Euro (2014-2025)). Still, 7% better. Are the chosen years the best possible for comparison, as revenue and production vary? It would be nice to see a similar comparison for other companies as well.
