Listen to the news

UPM-Kymmene Oyj (HLSE:UPM) has brought its Leuna biorefinery in Germany into operation. The €1.37b investment converts wood-based biomass into renewable chemicals for sectors ranging from packaging and clothing to tires.

Investors have already been reacting to these moves. UPM-Kymmene Oyj’s share price is at €25.19, with a 7.42% 90-day share price return and a 20.19% total shareholder return over one year. However, the 3-year total shareholder return is slightly negative, which suggests momentum is relatively recent.

UPM-Kymmene Oyj now trades only slightly below analyst targets, while its own intrinsic value estimate implies a much wider gap. Is the Leuna step change already reflected in the price, or not yet?

Most Popular Narrative: 1% Undervalued

On the narrative view, UPM-Kymmene Oyj screens slightly undervalued, with an estimated fair value of about €25.57 against the latest close at €25.19. This shifts the discussion away from simple momentum and toward what really drives cash flow over the next decade.

The main priority is that UPM executes its portfolio simplification and transformation while managing the cash drag from Leuna, working capital build-up and higher leverage, so that earnings from Energy, Fibres South and specialty materials offset headwinds from Communication Papers and biochemicals start-up losses.

See why 33 investors see UPM-Kymmene Oyj as 1% undervalued.

Result: Fair Value of €25.57 (UNDERVALUED)

Still, the thesis can break if Leuna’s capital needs and start up losses weigh longer on cash flow, or if working capital remains tied up and keeps leverage elevated.

Another View: UPM-Kymmene Oyj Through the P/E Lens

The first narrative frames UPM-Kymmene Oyj as slightly undervalued around €25 per share. On a simple P/E check, the picture looks less generous. The stock trades at 21.3x earnings, compared with 12.8x for peers and 15.4x for the wider forestry group, while the fair ratio sits higher at 24.7x.

A higher multiple than both peers and the industry means you are paying a premium today, even if that fair ratio indicates the market could move closer to 24.7x over time. The question is whether that premium feels like a safety margin for quality or a source of valuation risk if growth expectations cool.
