Inter Parfums [IPAR] — Trade Construction

The memo issues no position verdict.

Vehicle: EQUITY

Equity is the default and needs no argument. Trailing 252-day realised vol 30.2% — the lowest of the three names in this cluster. IV not measured, so no LEAP argument is made; an unmeasured IV/RV spread is not an argument.

There is, unusually, a genuine catalyst that could support a dated structure — the three licence expiries on 2026-12-31 — but a licence renewal is not an announced event with a scheduled date; it is a negotiation whose outcome is typically disclosed after the fact (GUESS renewed in December 2025, Van Cleef in December 2024, Coach in March 2025 — all disclosed on completion, none pre-announced). So there is no date to place an expiry against, and the vehicle remains equity.

Invalidation — quantified, checkable, from disclosure that already exists

  1. Promotion & advertising above 21.5% of net sales for a full year. The terminal margin assumes exactly 21.0%, which is management's own target. Overshoot means the brands need more support than guided, and 0.5pp of revenue is ~$8m of EBIT.
  2. Royalty expense above 8.6% of net sales. It has drifted 7.9% → 8.1% → 8.2% and the terminal assumes 8.4%. Faster drift means the incoming brand mix is structurally more expensive.
  3. Non-renewal of any brand in the disclosed 77%-of-sales table, or a renewal on visibly worse terms (detectable through the royalty rate). Dunhill in 2024 is the precedent that this happens.
  4. Same-quarter DSO above 95 days. Q1'26 was 91.7d against 83.2d a year earlier, on 1.8% revenue growth — receivables grew 6.7x revenue. This is the one genuinely adverse operating trend on the name and it is the earliest warning of soft sell-through.
  5. Revenue growth below 0% for two consecutive quarters. The required 6.7% CAGR already sits above the 1.8% latest print; outright decline breaks the reverse-DCF PASS entirely.
  6. Exercise of the Lanvin repurchase right on 2027-07-01 at €70m.

Sizing constraint

size_bucket: mid, $4.05bn market cap, 30.2% realised vol — the lowest of the three. evidence_grade A−, the most robust exit-multiple sensitivity of the cluster (flip point 12–13x against a 14.0x base, passing across a 2x range), and the only 12-month target of the three that is both IDENTIFIED and above spot.

The offsetting constraint, and it is structural rather than a matter of confidence: 28% of the economics of 68% of the revenue belong to someone else. An investor buying IPAR equity is buying a 72% claim on Interparfums SA plus 100% of the smaller US business. That is correctly handled in the EV (NCI added) and it also means the effective free float of the underlying earnings stream is smaller than the market cap implies. Per valuation.md rule 5, this reduces size and does not touch the operating assumption.
