## Questions

### What is Poseidon Investment Management's investment mandate?

Poseidon runs a long/short equity mandate focused strictly on plant-touching cannabis and hemp companies — those that cultivate, process, distribute, or brand the plant. The firm excludes ancillary service providers, concentrating instead on multistate operators, licensed producers, and consumer packaged goods. This deliberate scope dates to its 2014 inception.

### Does Poseidon only invest in public equities?

No. While the fund maintains a public-markets core, it also allocates to private, late-stage venture rounds. This hybrid structure lets Poseidon participate in growth-stage raises before companies list while retaining the ability to short public names when regulatory or operational risks materialize.

### How is Poseidon's strategy different from other cannabis investment vehicles?

Most cannabis-dedicated funds are either venture-only shops or broad life-sciences portfolios that treat cannabinoids as one of many biotech themes. Poseidon combines a public long/short book with private placements, giving it tools to profit from both upside and downside across the volatile regulatory cycles that define the industry.

### Where does Poseidon source and deploy its capital geographically?

The firm's primary geographic exposures are the United States, Canada, and Germany — the three largest federally regulated cannabis markets. Poseidon maintains dual headquarters in Berlin and San Francisco to stay proximate to regulatory developments on both continents, and it monitors Latin American and EU frameworks for future expansion.
