## Questions

### How is Neptunia Invest structured as an investment vehicle?

Neptunia is a Swedish investment company with corporate bonds listed on Nasdaq Stockholm. It operates as a permanent-capital vehicle, meaning it holds core assets indefinitely rather than cycling through funds with defined lifespans. The capital base combines private equity from founders and co-investors like the Ehrnrooth family with public debt-market funding.

### What is Neptunia's relationship with Slättö and MW Group?

Slättö and MW Group are Neptunia's original core holdings, founded separately by Johan and Mikael Karlsson before the 2014 formation of Neptunia. Slättö is a real estate fund manager investing in Nordic properties across several thematic strategies. MW Group provides services to critical infrastructure and total defense customers in the same region. Both remain core, long-duration holdings.

### Does Neptunia Invest do minority investments or only control deals?

Since 2019, Neptunia has built a minority-stake portfolio focused on entrepreneur-led companies with digital business models. These positions sit alongside its controlling core holdings in Slättö and MW Group. The firm describes itself as 'one of several significant investors' in these minority deals, adding capital and industrial networks rather than seeking full operational control.
