Layer 1 — GP1
Product Margin Compression
Non-compliant third-country supply chains mask mandatory costs:
CE testing, EU representative registration, and local-language
documentation. These are not optional — they are structural COGS
additions triggered by any post-close compliance programme.
Correction: Mandatory testing, registration, and
documentation add fixed costs directly to cost of goods sold,
compressing reported GP1.

Layer 2 — GP2
Logistics Margin Attrition
Missing Extended Producer Responsibility (EPR) registration and
packaging taxation avoidance across EU member states creates
retroactive financial exposure that inflates reported fulfilment
margins. Cross-border operators frequently accumulate multi-year
EPR liabilities invisible to the data room.
Correction: Retroactive EPR registration and
structural compliance fees squeeze fulfilment margins on a
recurring, not one-time, basis.

Layer 3 — GP3
Contribution Margin Collapse
Conversion rates engineered through non-compliant dark patterns —
fake scarcity timers, restricted cookie consent flows, obfuscated
subscription traps — are illegal under EU Omnibus and DSA
frameworks. Post-acquisition compliance enforcement causes
conversion to normalise to legal baselines, spiking Customer
Acquisition Cost.
Correction: Enforcing Omnibus/DSA compliance
drops conversion to legal baselines. CAC spikes. Contribution
margin collapses. The LTV/CAC model used to justify valuation
breaks.
