How do employee co-determination rules affect valuation?

Co-determination thresholds:

• Above ~500 employees: one-third of the supervisory-board seats for employees.
• Above ~2,000 employees: half-and-half parity (with a tie-breaking vote for the chair).
• Certain heavy industries (steel, mining, above ~1,000 employees): full parity without a tie-breaking vote. Valuation implications: (1) reduced restructuring flexibility: site closures and headcount reductions require redundancy-plan negotiations with the works council — typically 1–2 months' salary per employee per year of service. (2) Reduced M&A speed: supervisory-board approvals for strategic decisions. (3) Operating-margin discount: empirically 50–150 bps lower EBITDA margins vs. low-co-determination comps (UK, US). (4) PE pitfall: many (US-centric) PE sponsors underestimate co-determination restrictions. Strategic workarounds: a European Company (SE) form with a frozen co-determination quota, or holding structures with operating subs below the threshold.
