Innovative Industrial Properties Increases Mezzanine Loan by $267M

What Happened

• Innovative Industrial Properties, Inc. (through subsidiary IIP Life Science Investments II LLC) announced a Sixth Amendment to an existing mezzanine loan on September 28, 2026, raising the loan facility by $267.0 million to a total maximum principal of $400.0 million.
• Under the amendment IIP Life Science II will provide up to $245.0 million under a new Mezzanine Promissory Note B (Note B) and the existing mezzanine lender will provide up to $22.0 million under a new Note C. IIP Life Science II funded an initial advance of approx. $111.0 million on the closing date, which repaid an $85.0 million bridge loan and paid related fees and costs.
• The amendment extends the mezzanine loan maturity to February 9, 2028 (with a further one-year extension option subject to conditions) and sets the Applicable Rate at the greater of 14% per annum or (initially) one‑month Term SOFR plus 9.0% (with possible alternate rate conversions).

Key Details

• Loan increase: $267.0 million (total mezzanine facility now $400.0M).
• IIP commitment: up to $245.0M under Note B; existing lender: up to $22.0M under Note C. Initial advance by IIP ~ $111.0M (Sept. 28, 2026).
• Use of proceeds: repay prior bridge loan, pay closing fees/costs, fund debt service/fees; remaining Note B funds may finance tenant improvements, landlord work and campus amenities for Alewife Park subject to conditions.
• Additional agreements: Co‑Lender Agreement (allocates lender rights; IIP has consent and control rights on certain actions), Right of First Offer (ROFO) on Alewife Park that becomes effective once Note B funding reaches $155.0M, and amendment to the intercreditor agreement with senior lenders.

Why It Matters

• The company has materially increased its mezzanine exposure (upside from mezzanine returns and ROFO) and provided immediate liquidity to the borrower (repaying the bridge loan). The financing includes a high interest floor (14% p.a. minimum), indicating elevated yield potential tied to mezzanine risk.
• The ROFO gives IIP a contractual first look to purchase, finance or refinance Alewife Park once certain funding thresholds are met, which could create future acquisition or financing opportunities for IIP. The maturity extension to Feb 2028 reduces near‑term refinancing pressure on the mezzanine position.
• Investors should note the enlarged commitment, the initial $111.0M advance already funded, and that further advances and any purchase of the existing lender’s notes are subject to conditions (including steps to preserve IIP’s REIT qualification). The company furnished a press release and investor presentation on Oct. 1, 2026.
