Exhibits 99.1 and 99.2, respectively.

The information contained in Item 7.01 of this

Current Report on Form 8-K, including Exhibits 99.1 and 99.2, is being furnished and shall not be deemed “filed” for

purposes of Section 18 of the Securities Exchange Act of 1934, or otherwise subject to the liabilities of that section. Such information

shall not be incorporated by reference into any filing of the Company, whether made before or after the date hereof, regardless of any

general incorporation language in such filing.

Item 8.01 Other Events.

Purchase Agreement

On June 9, 2026, the Company and IIP

Operating Partnership, LP, the operating partnership subsidiary of the Company (the “Operating Partnership”), entered

into a purchase agreement (the “Purchase Agreement”) with BTIG, LLC, as representative of the initial purchasers

(collectively, the “Initial Purchasers”), pursuant to which the Operating Partnership agreed to sell, and the Initial

Purchasers severally agreed to purchase, $402.5 million aggregate principal amount of the Operating Partnership's 6.000%

exchangeable senior notes due 2029 (the “Notes”), including the full exercise by the Initial Purchasers of their option

to purchase an additional $52.5 million aggregate principal amount of Notes in a private offering (the “Offering”).

The Offering is expected to close on June 15,

2026, subject to the satisfaction of customary closing conditions.

The Notes will be senior unsecured obligations

of the Operating Partnership, will be fully and unconditionally guaranteed by the Company and will be exchangeable for cash, shares of

the Company’s common stock, or a combination of cash and shares of the Company’s common stock, at the Operating Partnership’s

option. The initial exchange rate for the Notes will be 14.4113 shares of the Company’s common stock per $1,000 principal amount

of Notes and the initial exchange price will be approximately $69.39 per share of the Company’s common stock. The initial exchange

rate and initial exchange price are subject to adjustment in certain circumstances. The Notes will pay interest semiannually at a rate

of 6.0% per annum and will mature on June 15, 2029, unless earlier exchanged or repurchased in accordance with their terms. The Operating

Partnership will not have the right to redeem the Notes prior to maturity, but may be required to repurchase the Notes from holders under

certain circumstances.

In addition, following the occurrence of certain

corporate events that occur prior to the maturity date, the Operating Partnership will, in certain circumstances, increase the exchange

rate for a holder that elects to exchange Notes in connection with such corporate event.

The Operating Partnership intends to use $80.5

million of the net proceeds from the Offering to fund the repurchase of 1,334,106 shares of the Company’s common stock from certain

purchasers of the Notes in privately negotiated transactions. The Operating Partnership intends to use the remaining net proceeds from

the Offering for working capital and general corporate purposes, which may include repayment of indebtedness and funding investments that

are consistent with its investment strategy, or a combination of the foregoing.

The Notes, including the guarantee, and the shares

of common stock issuable upon exchange of the Notes, have not been and will not be registered under the Securities Act of 1933, as amended

(the “Securities Act”) and may not be offered or sold in the United States absent registration or an applicable exemption

from registration requirements. The Operating Partnership is offering and selling the Notes to the Initial Purchasers in reliance on the

exemption from registration provided by Section 4(a)(2) of the Securities Act. The Initial Purchasers will initially offer the Notes for

resale to persons reasonably believed to be qualified institutional buyers (as defined in the Securities Act) pursuant to the exemption

from registration provided by Rule 144A under the Securities Act.

This Current Report on Form 8-K does not constitute

an offer to sell, or a solicitation of an offer to buy, any security and shall not constitute an offer, solicitation or sale in any jurisdiction

in which such offer, solicitation or sale would be unlawful.

Repayment of 2026 Senior Notes

On May 26, 2026, the Company fully repaid the outstanding

$282 million of its 5.50% Senior Notes due 2026 (the “Notes due 2026”), which were senior unsecured obligations of the Operating

Partnership, fully and unconditionally guaranteed by the Company, and matured on May 25, 2026. The repayment amount represented 100% of

the principal amount plus accrued and unpaid interest to the repayment date. The repayment was completed through cash on hand, availability

under the Company’s credit facility pursuant to a loan and security agreement between the Operating Partnership and a federally

regulated commercial bank, which matures on October 23, 2026, and was most recently amended in November 2024 to increase aggregate commitments

for secured revolving loans to $87.5 million, availability under the Company’s credit facility pursuant to a loan agreement between

the Operating Partnership and IIP Life Science Investments LLC, a wholly owned subsidiary of the Operating Partnership, and a federally

regulated commercial bank, which provides for a revolving line of credit available up to $100.0 million until the maturity date on October

3, 2028, and net proceeds from four secured term loans previously disclosed in the Company’s filings with the SEC: a $20.0 million

term loan from Generations Bank maturing April 22, 2029; a $56.5 million term loan from Thorofare Asset Based Lending Reit Fund V, LLC

maturing May 5, 2029; approximately $44.9 million of term loans from Amalgamated Bank maturing June 5, 2031; and a $20.0 million term
