In particular, statements pertaining to our capital resources, portfolio performance and results of operations contain forward - looking statements. Likewise, our statements regarding anticipated growth in our funds from operations and anticipated market an d regulatory conditions, our strategic direction, our dividend rate and policy, demographics, results of operations, plans and objectives are forward - looking statements. Forward - looking statements involve num erous risks and uncertainties, and you should not rely on them as predictions of future events.

We do not guarantee that the transactions and events described will happen as described (or that they will happen at all). You can identify forward - looking statements by the use of forward - looking terminology such as "believes," "expects," "may," "will," "should," "seeks," "approximately," "intends," "plans," "estimates" or "anticipates" or the negative of these words and phrases or simi lar words or phrases. You can also identify forward - looking statements by discussions of strategy, plans or intentions. The following factors, among others, could cause actual results and future events to differ ma ter ially from those set forth or contemplated in the forward - looking statements: our business and investment strategy; our projected operating results; actions and initiatives of the U.S. or state governments and change s t o government policies and the execution and impact of these actions, initiatives and policies, including the fact that cannabis remains illegal under federal law; availability of suitable investment opportuniti es in the medical - use cannabis industry; concentration of our portfolio of assets and limited number of tenants; our understanding of our competition and our potential tenants' alternative financing sources; the estimat ed growth in and evolving market dynamics of the medical - use cannabis market; the demand for medical - use cannabis cultivation and processing facilities; the expected medical - use or adult - use cannabis legalizati on in certain states; shifts in public opinion regarding medical - use cannabis; the state of the U.S. economy generally or in specific geographic areas; economic trends and economic recoveries; our ability to access eq uity or debt capital; financing rates for our assets; our expected leverage; changes in the values of our assets; our portfolio of assets; our investments; interest rate mismatches between our assets and our borro win gs used to fund such investments; changes in interest rates and the market value of our assets; rates of default on leases for our assets; the degree to which any interest rate or other hedging strategies may or may not protect us from interest rate volatility; impact of and changes in governmental regulations, tax law and rates, accounting guidance and similar matters; our ability to maintain our qualification as a real est ate investment trust for U.S. federal income tax purposes; our ability to maintain our exemption from registration under the Investment Company Act of 1940; availability of qualified personnel; and market trends in our industry, interest rates, real estate values, the securities markets or the general economy. The risks included here are not exhaustive, and additional factors could adversely affect our business and financial performa nce .

Those risks continue to be relevant to our performance and financial condition. Moreover, we operate in a very competitive and rapidly changing environment. New ris k factors emerge from time to time and it is not possible for management to predict all such risk factors, nor can it assess the impact of all such risk factors on our business or the extent to which any facto r, or combination of factors, may cause actual results to differ materially from those contained in any forward - looking statements.
