    Mersen (ENXTPA:MRN) Stock Faces Valuation Heat After Guidance Upgrade

    Simply Wall St·08/01/2026 00:35:18
    Listen to the news

    Mersen stock closed at €37.24 on Friday, roughly flat over the past week after a weak month and a stronger quarter. The market reaction has been cautious, yet the H1 2026 release is built around one clear headline. The company lifted its full year guidance on the back of €611m in sales and an EBITDA margin of 15.9%, signalling firmer profitability in its electrical and advanced materials businesses.

    Short term traders are watching a volatile chart. Longer term investors are now weighing those margin targets and the multi year roadmap against a still demanding 57.7x trailing P/E and a sizeable €400m net debt load.

    Is Mersen at €37.24 a genuinely undervalued story after a one off €48.9m hit to earnings, or just expensive on a 57.7x trailing P/E? Compare the current share price against detailed cash flow assumptions in the valuation analysis for Mersen.

    H1 2026 Earnings Summary

    • Revenue H1 2026 vs. H2 2025: €611m vs. €576m (stable half-on-half performance based on reported figures)
    • Net Income H1 2026 vs. H2 2025: €15.6m vs. a loss of €15.2m (swing back to profit, with reported margin for the last 12 months at 1.3% vs. 4% the prior year)
    • Basic EPS H1 2026 vs. H2 2025: €0.64 vs. a loss of €0.62 per share (return to positive earnings per share after the one-off €48.9m hit)
    • EBITDA Margin H1 2026 vs. FY 2025 guidance range: 15.9% vs. prior full-year target range of 16.0% to 16.5% (profitability running close to the upgraded full-year goal)

    Mersen’s Bull Story Hinges On Execution Milestones Hit

    Bulls argue that Mersen is moving from promise to delivery in EV, semiconductors and data centers, with better cash discipline to match. The H1 2026 numbers give some support to that view. Electrical Power is clearly pulling its weight, with data center and EV busbar activity singled out as the main driver of H1 outperformance. Management also reports that ACC busbar shipments were about 3x last year, even if they are still behind the customer’s schedule, which shows progress but not full proof yet.

    In Advanced Materials, silicon semiconductor revenue above €30m in H1 and SiC sales of about €25m point to real volume in higher value niches. The raised full year organic growth and margin guidance, combined with lower planned CapEx, indicates that Mersen is at least starting to meet the operational milestones that the bullish narrative relies on.

    Mersen Bear Case: Cyclicality Fears Not Fully Put To Bed

    The bearish view on Mersen is that heavy exposure to cyclical solar, semiconductors and EVs, combined with a large capex program, leaves earnings and cash flow fragile. H1 2026 does not fully close that file. Electrical Power and silicon semiconductor demand supported a 15.9% EBITDA margin, yet chemicals and solar in Europe are still weak with chemical sales of about €45m, down 15 to 20% year on year. That validates concerns about uneven end markets.

    Bears also worry that big capacity bets, especially in SiC, could run ahead of demand and keep leverage high. Net debt of €400m and leverage around 2.3x leave limited room for further missteps. Working capital increased by about €45m in H1, which keeps the pressure on cash conversion. Guidance is higher, but several key risks flagged by skeptics, particularly cyclicality and balance sheet stretch, remain in play.

    After a one off €48.9m earnings hit, a 1.3% net margin and €400m net debt, it is worth asking if these are isolated issues or signs of deeper structural pressure. Scan the risk analysis for Mersen which shows 5 important warning signs
