EU Portfolio weekly review: concentrated, but still on thesis
The EU Portfolio currently holds one open position: THEON International Plc. The stored portfolio quote history shows a flat return of 0.00%, with the first and latest stored quote both dated May 26, 2026 at 37.4400. Because the pick date is May 31, 2026 and the latest stored quote predates the pick date, the performance record should be treated as stale until the quote feed refreshes.
Positioning and portfolio fit
THEON remains a valid fit for the EU Portfolio’s region/country discipline. The company is listed on Euronext Amsterdam under the main line AMS: THEON, while the portfolio record displays TNIPF. That mismatch should be checked operationally: for an EU-focused portfolio, the preferred implementation is the Amsterdam ordinary share line, not a thin OTC proxy. However, this is a monitoring item rather than a reason to close the position this week.
Recent performance drivers
The fundamental setup remains constructive. In its Q1 2026 trading update, THEON reported revenue of €120.1 million, up 32.3% year over year, adjusted EBITDA of €31.8 million, and an adjusted EBIT margin of 25.0%. The company also reported soft backlog of €1.420 billion and options on soft backlog of €896.9 million at March 31, 2026.

Order intake was lower year over year in Q1, which is the main point to watch, but management attributed the decline largely to seasonality and maintained confidence in FY 2026 guidance and a book-to-bill ratio above 1.0x. That matters because the portfolio thesis depends on continued European defense procurement, not just prior backlog conversion.

The latest order update supports the hold decision. On June 1, 2026, THEON announced approximately €42 million of new Q2 orders to date, plus €27 million of associated options, with a significant portion tied to Kappa Optronics vehicle-awareness systems for armored vehicles in an EU country. Management said year-to-date order intake and new options stood at €144 million and €67 million, respectively.

Risk concentration
The portfolio’s biggest risk is simple: it is a one-stock portfolio. That creates concentration in one company, one industry cluster, and one macro driver: European defense spending. THEON is also an acquisition-and-integration story, with Kappa, ShockEOS, Exosens exposure, Varjo funding and MERIO-related expansion all adding strategic upside but also execution risk. The Q1 update also showed net debt of €228.2 million at March 31, 2026, compared with net cash at year-end 2025 after rights-issue proceeds, so balance-sheet discipline and cash conversion deserve close attention.

What to watch next
- Quote-feed integrity: confirm that the portfolio is tracking the Amsterdam-listed ordinary shares, not only the TNIPF OTC reference.
- Order conversion: monitor whether H2 and Q4 order seasonality delivers enough intake to sustain book-to-bill above 1.0x.
- Margins: THEON’s 25% adjusted EBIT margin is a strength; any acquisition-related compression would be important.
- Working capital and net debt: defense growth can consume cash before deliveries are paid for, so cash conversion remains central.
- Valuation discipline: the position should not be sold merely because it is volatile, but a sharp re-rating without matching order growth would change the risk/reward.
Portfolio action
Decision: Hold THEON. Do not close the position this week. There is no thesis break, catalyst failure, or evidence of deteriorating fundamentals. The position is concentrated, but the company remains aligned with the EU Portfolio’s objective: exposure to European-listed equities benefiting from regional industrial and defense-policy priorities.
