On January 29, 2015, Capital Senior Living Corporation (the “Company”) issued a press release announcing the acquisition of two senior living communities (the “ Acquired Communities”) for a purchase price of $32.8 million. The Acquired Communities are comprised of 127 assisted living units and are located in regions in which the Company already has extensive operations. The acquisition of the Acquired Communities, which have both been completed, was financed with $24.5 million of 10-year fixed-rate debt with a blended interest rate of 4.41%.

In addition, the press release announced that the Company has completed the sale of four non-core senior living communities (the “Sold Communities”) for $36.5 million and will receive approximately $18.0 million of net proceeds after relieving the debt associated with the Sold Communities and paying customary transaction and closing costs. The Sold Communities were comprised of 547 independent living units.

The press release also announced that the Company has refinanced the existing debt associated with one of its communities.

A copy of the Company’s press release is attached as Exhibit 99.1 to this Current Report on Form 8-K.

The press release contains, and may implicate, forward-looking statements regarding the Company and includes cautionary statements identifying important factors that could cause actual results to differ materially from those anticipated.
