## Questions

### Who runs investment decisions at Stena Adactum?

President and CEO Anders Wassberg leads the investment team, which includes senior partners Johan Wester, Henrik Hallin, and Henrik Munthe. Decisions are made by the nine-person team in Gothenburg. The firm operates with a flat structure where principals sit on portfolio company boards and drive operational strategy directly.

### How does Stena Adactum source proprietary deal flow?

The firm sources through the Stena Sphere's industrial network and direct relationships with Nordic business owners. It targets profitable mid-market companies with established market positions, often founder- or family-led, across Sweden and the surrounding region. The permanent-capital structure and absence of a fixed holding period often appeal to sellers seeking a long-term steward.

### Is Stena Adactum structured as a private equity fund or something different?

It is not a fund. Stena Adactum is a wholly owned investment company within the Stena Sphere — a family-owned corporate group. It deploys permanent balance-sheet capital from the Olsson family and reinvests proceeds, with no external limited partners and no predetermined exit timelines.

### Does Stena Adactum take majority or minority positions?

Both. The firm holds several wholly owned portfolio companies — such as Ballingslöv International and Envac — while also taking minority stakes in listed entities, including a 5.8% position in Inwido. The website references active board participation in all holdings, regardless of stake size.

### What is Stena Adactum's stated investment horizon?

The firm explicitly states it has no predetermined investment horizon. Its target is to double portfolio value every five years through active board work and operational improvement. The permanent-capital structure supports indefinite holding periods, with companies held for generations rather than fund cycles.
