Cross-Border Deal — Pricing PolnaChem for ESG, Trust & Discipline

A four-round, advanced corporate-finance and M&A simulation. You lead M&A at Hexagone Matériaux SA, a Euronext-listed €2.1B French specialty-materials group (17% EBITDA margin, €357M; net debt 1.8x EBITDA) under a board mandate to enter Central/Eastern Europe by acquisition and a net-zero-by-2040 commitment that ties its cost of capital to its ESG profile. The target is PolnaChem Sp. z o.o., a profitable founder-owned Polish specialty-coatings producer (€60M EBITDA). Its owners want 8.5x EBITDA (≈ €510M); comparable European coatings deals trade at 6.5–7.0x. The target carries a +40% carbon-intensity gap, two sites without EU-aligned permits (≈€45M remediation capex over three years), and a trust differential — the founder personally holds the top customer relationships and a low-trust integration historically destroys 20–30% of synergy. A rival bidder is circling and the board caps post-close leverage at ≤2.5x EBITDA (an all-cash 8.5x bid hits 2.7x, breaching the ceiling). Hexagone's last cross-border deal failed precisely because the team priced on financials alone and was blindsided by ESG liabilities and a collapse of trust; the board has now made ESG and trust diligence mandatory in the investment case. Round 1 — Screen & diligence: run the two mandated lenses (ESG: permits, carbon, remediation, transition risk; trust: founder dependency, retention risk, cultural distance) against the rival's clock, and read the findings for what the financials don't show. Round 2 — Price the bid: adjust the valuation explicitly for ESG (remediation capex, transition risk, the green cost-of-capital effect) and trust (a 25% synergy haircut), then set a disciplined walk-away and an opening bid — a premium over comps is only justified by realisable synergy, and crossing your own walk-away is the winner's curse. Round 3 — Structure under the financing constraint: choose the cash/equity mix to stay under the 2.5x ceiling, an earn-out tied to ESG-compliance and customer-retention milestones, a founder lock-in with enhanced reps-and-warranties, and whether to use a sustainability-linked facility (≈35 bps margin benefit). Round 4 — Recommend to the investment committee and react to a live rival escalation to 8.7x: hold, raise, or walk, and defend the integrated case (price, ESG-and-trust adjustments, structure, financing cost, completion probability) together. The model rewards diligence-as-value-protection, ESG-and-trust-adjusted pricing, walk-away discipline, structuring within the leverage ceiling, and the use of sustainability-linked finance — and punishes the five classic errors via sticky penalty gates: financials-only pricing, the winner's curse, ignoring founder dependency, breaching the financing ceiling, and skipping diligence for speed. Final KPIs track Deal NPV (value created, €M), completion probability (%), post-close leverage (× EBITDA) and an ESG-&-trust risk index. Winning the asset and creating value are not the same thing.
