Mersen S.A. (CBLNY) Q4 2025 Earnings Call Transcript

Mersen described 2025 as a year of resilience despite an EV cycle slowdown and notable weakness in solar, with tariffs (referencing US policy) a past concern that ultimately did not derail the year. Management announced Salvador Lamas will replace CEO Luc Themelin in May and flagged strategic successes in India that management expects will pay off going forward.

Analysis

Mersen’s recent commentary implies the business mix and geographic footprint are dampening volatility from the EV and solar cycles — the non-obvious benefit is optionality from localized production wins (India) that shorten lead times and reduce import tariff exposure, effectively converting top-line cyclicality into margin durability over 6–18 months. Operationally, that should compress working capital swings and improve free cash flow conversion in down-cycles, which is asymmetric upside if end markets reaccelerate.

The management succession in May is a near-term catalyst with an outsized second-order effect: new leadership typically accelerates portfolio pruning or commercial reallocation within 3–9 months. That increases the probability of either targeted reinvestment behind higher-return industrial segments or divestitures of low-growth solar/EV exposure; both outcomes materially change valuation peers and relative multiples.

Primary tails are policy/tariff reversals and renewed EV/solar destocking: a reintroduction of restrictive trade measures or a deeper demand shock would quickly re-expose revenue concentration and compress margins within a 1–4 quarter window. Conversely, continued localization and successful India ramp create a 12–24 month runway for margin expansion of 150–300bps versus the recent run-rate, implying 25–40% equity upside under execution.

From a competitive standpoint, suppliers tightly tied to North American EV supply chains are more exposed to demand troughs; Mersen’s diversified exposure and onshore manufacturing make it a relative winner if the macro stays soft but policy volatility remains elevated. Monitor raw material inflation (copper/graphite inputs) and FX — each can swing EBITDA margins by several hundred basis points in a single quarter and are plausible reversal channels for the thesis.

Key Decisions for Investors

• Long Mersen (CBLNY) equity, 6–12 month horizon: position size 2–4% portfolio. Rationale: optionality from India ramp and management change. Target 30% upside if margins expand 150–300bps; stop-loss 20–25% if orderbooks deteriorate or tariffs reappear.
• Buy-call spread (debit) on Mersen: buy Jan 2027 CBLNY call, sell a higher strike to finance ~50–60% of premium. Time to exploit 12–18 month operational improvements while capping premium outlay. Expected payoff 2–4x if execution triggers margin re-rating; max loss = paid premium.
• Pair trade for sector-neutral exposure: long CBLNY vs short Aptiv (APTV) 6–9 months, 1:1 notional. Rationale: play Mersen’s diversification/localization vs Aptiv’s higher EV cycle sensitivity. Win if EV/solar demand softens or if localization premium is priced in; risk if broad auto recovery re-rates APTV more than Mersen.
• Event hedge: buy out-of-the-money puts on CBLNY expiring in 3–6 months sized to cover 50% of the equity position prior to May CEO transition. This protects against a negative governance surprise or clear execution miss through the change in leadership.
