Monitor the final pricing and size of the Series B Preferred offering once the prospectus supplement is completed. The key risk is the execution and credit performance of the large Alewife Mezzanine Loan, which is structurally subordinate to a senior mortgage and secured by non-cash-flowing collateral. Watch for any future updates on the loan's performance or IIPR's ability to service the new preferred dividends.

Risk Factors
- The Alewife Mezzanine Loan is structurally subordinate to a senior mortgage and secured by non-cash-flowing collateral, increasing credit risk.
- The offering increases financial leverage and leverage exposure to the life science real estate, a sector with higher risk than core cannabis properties.
- The Series B Preferred Stock is a new issue with no established trading market and has not been rated, potentially limiting liquidity.
- IIPR's ability to pay dividends on the new preferred stock is subject to board discretion and legal constraints, including Maryland law and debt covenant restrictions.
- The mezzanine loan's qualification as a real estate asset for REIT tests is subject to IRS safe harbor, and failure could jeopardize REIT status.
