IASIS HEALTHCARE EXECUTES REAL ESTATE TRANSACTION

AS PART OF LONG-TERM STRATEGIC GROWTH PLAN

FRANKLIN, Tennessee (August 14, 2013) – IASIS Healthcare^® LLC (“IASIS”), a leading provider of high quality, affordable healthcare services, today announced the execution of a sale-leaseback agreement with Medical Properties Trust, Inc., (“MPT”), the healthcare real estate investment trust (“REIT”) that currently owns property associated with another IASIS facility. This new agreement involves the land and buildings associated with Glenwood Regional Medical Center (“Glenwood”) in West Monroe, LA; Mountain Vista Medical Center (“Mountain Vista”) in Mesa, AZ; and The Medical Center of Southeast Texas (“Medical Center”) in Port Arthur, TX.

The transaction is expected to generate $281.3 million in proceeds, which IASIS plans to use in a variety of strategic initiatives aimed at, among other things, growth in existing markets and expansion into new markets. After the transaction, IASIS will continue to own and operate the business of these three hospitals, but will lease the land and the buildings associated with these facilities from MPT at attractive, long-term lease rates.

“The access to capital and low interest rates available currently to companies like ours is somewhat unprecedented and has created an exceptionally attractive financing opportunity that will allow us to transition capital currently locked up in our real estate to cash on hand, which we can put toward our mission of improving the quality of life for the communities we serve,” said IASIS Healthcare President and Chief Executive Officer Carl Whitmer. “Consistent with the recently announced divestiture of our Florida operations, this asset management financing transaction will help position our company to take advantage of both current and future strategic growth opportunities.”

Whitmer continued, “There will be no changes for the Glenwood, Mountain Vista and Medical Center staff, physicians, patients or communities as a result of the sale-leaseback transaction. Instead, we will have even greater ability to invest in new growth opportunities and to increase competition for the benefit of the patients we serve in these three thriving communities, as we proudly have been doing now for many years.”

The long-term lease agreements between IASIS and MPT provide for attractive rates, terms and renewal options. IASIS and MPT expect there will be opportunities for future expansion at each of the facilities. The agreement also includes a right-of-first refusal clause that gives IASIS the opportunity to repurchase any and all assets, should MPT decide to sell. Additionally, IASIS and MPT have agreed to an amendment at IASIS’ Pioneer Valley Hospital in West Valley City, Utah, that reduces the rent, provides for $2 million in capital improvement projects funded by MPT and extends the term of the lease to 15 years. Subject to customary closing approvals and conditions, the transaction is expected to close prior to fiscal year end.
