Of that amount, we have sold shares of our common stock with an aggregate price of $95,498,040 as of the date of this prospectus supplement, pursuant to a Registration Statement on FormS-3 (FileNo. 333-208813) filed on December 31, 2015, and a prospectus supplement dated November 13, 2017. Accordingly, as of the date of this prospectus supplement, shares of our common stock having an aggregate offering price of up to $654,501,960 remain available for offer and sale pursuant to this prospectus supplement.
Our common stock is listed on the New York Stock Exchange, or the NYSE, under the symbol “MPW”. The last reported sale price of our common stock as reported on the NYSE on December 28, 2018 was $16.01 per share.
Sales of shares of our common stock, if any, may be made in negotiated transactions or transactions that are deemed to be“at-the-market offerings” as defined in Rule 415 under the Securities Act, including sales made directly on the NYSE or sales made to or through a market maker other than on an exchange or through an electronic communications network. The agents will make all sales using commercially reasonable efforts consistent with their normal trading and sales practices, on mutually agreed terms between the agents and us.
Pursuant to the terms of the equity distribution agreements, we will pay each agent a commission at a rate that will not exceed 2.0% of the sales price of all shares of common stock sold through it as our agent. We may also sell our common stock to the agents as principals for their own accounts at prices agreed upon at the time of sale.
To ensure that we maintain our qualification as a real estate investment trust, or REIT, our charter limits ownership by any person to 9.8% of the lesser of the number or value of shares of our outstanding common stock, with certain exceptions. See “Description of Capital Stock – Restrictions on Ownership and Transfer” in the accompanying prospectus.
Investing in our common stock involves risks. See “Risk Factors” onpage S-4 of this prospectus supplement as well as the risk factors set forth in our most recent Annual Report on Form10-K and Quarterly Report on Form10-Q.
