What Mersen Doubters Overlooked
If Mersen had been sitting on your watchlist instead of in your portfolio, the move over the past months might feel like a painful miss. For Mersen shareholders, the return from the start of the year was 68.1%, including dividends. That outcome invites a harder question. Back on 1 January 2026, what clues in the renewables and electrification growth story could have helped you judge whether modest 3.8% revenue growth assumptions were too cautious?
On Simply Wall St, a Narrative is an investor's thesis written down: the reasoning, plus the numbers it rests on. Run those numbers and you get an estimated Fair Value.
This theme extends beyond Mersen. See which of 43 power grid technology and infrastructure stocks may still merit a closer look.
The Argument Mersen Investors Were Really Weighing
The shares cost €23.85 at the start of the period, which meant any view on Mersen hinged on which story you believed about its future earnings power.
On the optimistic side, the bull Narrative saw renewable energy and electrification as growth engines, with a Fair Value of €28.37. That view leaned on assumptions of 3.8% annual revenue growth and profit margins reaching 7.2% within three years.
The bear Narrative argued that geopolitical risks and supply chain disruption could cap outcomes, with a Fair Value of €22. This scenario assumed margin pressure from elevated input costs and heavy capital spending that might restrain long term profitability.
What The Evidence Around Mersen Actually Tested
The clearest new data point for Mersen was the ultra high purity graphite story, where the company appears among key suppliers to EV battery and semiconductor demand. That supported the bullish view that advanced materials tied to electrification could matter. Half year 2026 results pointed in the same direction, with revenue at €611.5m and net income at €30.8m, and net margin at 5.0%. Overall, the evidence supported the optimistic case but only modestly.
The episode turned on whether modest revenue growth and gently higher profitability would actually show up. When you test a similar story elsewhere, track the direction of net margin and the segments mentioned in growth claims, then see if reported figures start to line up with that narrative.
What Mersen's Run Up 68% Now Asks You To Believe
Mersen now trades at €39.8, and the selected bullish narrative places its fair value above that level rather than below it. The current argument leans on renewables, electrification and power electronics turning recent contract wins into steadier earnings power.
On this view, anyone buying today would be assuming the market still understates how much future EV fuses, advanced materials and selected acquisitions could reshape Mersen's earnings mix.
"Anticipated recovery and long-term global growth in renewable energy projects (especially wind and an expected rebound in solar as suggested for H2 and beyond), together with structurally increasing power electronics and energy storage investments, are likely to drive sustained revenue growth as market conditions normalize and new contracts ramp up."

Looking Beyond Mersen’s Cables
Mersen pulls you into electrification, but your watchlist does not need to stop there.
Every extra EV charger and power module relies on heavier computing behind the scenes. Those systems run hot, and ordinary cooling often struggles to keep up.
One specialist focuses on the backbone that keeps those data centers functioning reliably. It builds power and thermal hardware that helps servers stay online under demanding AI and grid workloads.
The interesting twist is how heat and electricity intersect in this niche. As needs for both intensify, that supporting role could start to look far more central to infrastructure planning.
The case is on the record, with the assumptions it rests on. → See the Narrative that values this company 68% above its price
