Mainstreet Health Investments Announces US$425 Million Transformational Acquisition of 42 US Property Portfolio, New Strategic Investor and Name Change

Toronto, November 17, 2017 – Mainstreet Health Investments (TSX: HLP-U) ("Mainstreet" or the "Company") today announced that it has entered into definitive agreements with Tiptree Inc. (NASDAQ: TIPT) (“Tiptree”) and certain subsidiaries, to acquire Care Investment Trust, LLC (“CareIT”) (the “Transaction”) for an aggregate purchase price of approximately US$425 million (the “Consideration”). CareIT owns a portfolio of 42 seniors housing and care properties comprising 3,718 suites/beds in attractive markets across the United States (the “Portfolio”). Furthermore, Mainstreet intends to change its operating name to Invesque Inc., which will provide the Company with a unique and recognizable name.

Transformative and Strategic Acquisition

•

Attractive and Strategic Portfolio Acquisition: The Portfolio is comprised of 35 high quality independent living, assisted living and memory care properties and seven skilled nursing facilities located in growing markets across 11 states. The Portfolio is expected to add eight new states to Mainstreet’s existing platform and strengthens its presence in three states in which it currently owns properties. The Portfolio consists of 24 properties leased to operators under long-term triple-net leases and 18 operating properties in joint venture arrangements with seniors housing operators in which Mainstreet will own the majority of the real estate and the operations.


•	Enhanced Scale and Investment Platform: The Transaction increases the scale and scope of Mainstreet’s investment platform to comprise 80 properties with 8,536 suites/beds across the United States and Canada, a 2.6x increase compared to Mainstreet’s initial public offering in June 2016. The Company’s pro forma asset value is expected to increase to US$1.2 billion.

•

Transaction Significantly Improves Diversification: The Transaction further diversifies the Company’s operator relationships and geographic footprint. Mainstreet is expected to add eight new operators to its roster of high-quality operating partners and reduce the concentration of its largest operator Symphony, from 56% to 32%. Furthermore, assuming completion of the Transaction, Mainstreet will operate in 18 states and provinces and its concentration in the State of Illinois will be reduced to 31% from 54%.

•

Increases Exposure to Private Pay Sector: The Portfolio primarily consists of private pay independent living, assisted living and memory care properties that represent approximately 80% of the Portfolio’s suites/beds. Following the completion of the Transaction, Mainstreet’s portfolio will be comprised of approximately 52% independent living, assisted living and memory care suites and 48% skilled nursing and transitional care beds.


•	Attractive Transaction Metrics: The Consideration represents a going-in capitalization rate of approximately 7.7%. Mainstreet is funding the equity portion of the Consideration through the issuance of Mainstreet common shares directly to Tiptree.


•	Validation of Embedded Value and Addition of New Strategic Investor: Upon closing, Tiptree will become Mainstreet’s largest shareholder with an ownership interest of approximately 34%. Tiptree will receive Mainstreet shares based upon a fixed issuance price of US$9.75 per common share.


•	Accretive Transaction: The Transaction is expected to be accretive to the Company’s 2018E Adjusted Funds from Operations (“AFFO”) per share. The Company also expects to achieve additional synergies over time from operational efficiencies and debt consolidation, neither of which are included in the Company’s underwriting and financial analysis.

Scott White, the Company’s CEO stated, “We are excited to announce the acquisition of CareIT and deliver on our strategic plan to grow our platform, diversify our portfolio and provide significant value for our shareholders. We believe this transaction and the addition of Tiptree as another cornerstone investor will bolster our position in the market and position Mainstreet for the next phase of its growth. This transaction is further evidence of the embedded value in our platform, with a sophisticated investor making a significant investment in our Company.”

Rick Turner, the Company’s Chairman added, “This transaction is a significant achievement for our company and we are excited to announce this acquisition as we continue to deliver on our growth strategy. We expect to continue acquiring high quality properties with strong operators in growing markets.”

Michael Barnes, Tiptree’s Executive Chairman stated, “We are excited to partner with Scott and his team through the combination of our two platforms. We look forward to working together to further create value and upside for both companies’ shareholders.”

Transaction Overview

The consideration to be paid to Tiptree on closing of the Transaction will consist of the issuance of approximately 16.8 million Mainstreet common shares at a fixed issuance price of US$9.75 per common share (the “Equity Consideration”), subject to certain adjustments. Following the completion of the Transaction, it is expected that Tiptree will own approximately 34% of Mainstreet’s issued and outstanding common shares. In addition to the Equity Consideration, the Company will assume approximately US$261.2 million of in-place property level mortgage financing (the “Debt Financing”) with a weighted average interest rate of approximately 4.7% and a weighted average term to maturity of 4.9 years. Approximately US$114 million of the Debt Financing matures within the next three years, providing the Company with an opportunity to consolidate the property level mortgages into a corporate facility and achieve improved administrative and pricing synergies. The Company’s pro forma leverage will be approximately 57%.

Upon closing of the Transaction, subject to certain conditions set out in a governance and investor rights agreement (the “Governance and Investor Rights Agreement”), Tiptree will have the right to nominate one board member and one board observer (with no voting rights) to Mainstreet’s Board of Directors (the “Board”), which, upon the closing of the Transaction, will be comprised of a total of six board members. Also pursuant to the Governance and Investor Rights Agreement, Tiptree has agreed to a 24 month standstill (the “Standstill”) and to restrictions on the sale of its Equity Consideration for a period ranging from 6 months to 18 months. The Standstill prohibits Tiptree from taking certain specified actions without Mainstreet’s approval, including among other things, launching a takeover bid or increasing its ownership in Mainstreet.

The Transaction is subject to obtaining certain regulatory approvals, including Toronto Stock Exchange (“TSX”) approval, Mainstreet shareholder approval and other customary closing conditions, including consents of certain third parties. In accordance with Section 604(d) of the TSX Company Manual, the Company will initially seek shareholder approval for the issuance of the Equity Consideration by way of written consent of selected shareholders holding more than 50% of the issued and outstanding Mainstreet common shares. In that context, certain shareholders who together, currently own approximately 44% of Mainstreet’s common shares, have entered into voting support agreements in favor of the Transaction and have agreed to provide consents. If the Company is unable to obtain the balance of the requisite consents, the Company intends to call a meeting of shareholders to seek the foregoing approval. Assuming the requisite consents are obtained from shareholders, and customary regulatory and closing conditions are satisfied, the Transaction is expected to be completed during the first quarter of 2018.

Non-IFRS Financial Measures

FFO, AFFO and capitalization rate (which is a function of net operating income) are not measures recognized under IFRS and do not have a standardized meaning prescribed by IFRS. Such measures are presented in this news release because management of the Company believes that such measures are relevant in interpreting the purchase price metrics and performance of acquisitions. Such measures, as computed by the Company, may differ from similar computations as reported by other similar organizations and, accordingly, may not be comparable to the measures reported by such other organizations. Please see the Company’s most recent management’s discussion and analysis, which is available on SEDAR at www.sedar.com, for how the Company reconciles FFO, AFFO and net operating income to the nearest IFRS measure.

Forward-looking Information

This news release may contain forward-looking statements (within the meaning of applicable securities laws) relating to the business of the Company and the environment in which it operates. Forward-looking statements are identified by words such as "believe", "anticipate", “project”, "expect", "intend", "plan", "will", "may" "estimate", “pro forma” and other similar expressions.

The forward-looking statements in this news release are based on certain assumptions, including that all conditions to completion of the Transaction (including obtaining the written consent of selected shareholders holding more than 50% of the issued and outstanding Mainstreet common shares or otherwise obtaining shareholder approval at a meeting of shareholders) will be satisfied or waived, and that the Transaction will be completed. They are not guarantees of future performance and involve risks and uncertainties that are difficult to control or predict. A number of factors could cause actual results to differ materially from the results discussed in the forward-looking statements, including, but not limited to, risks that the conditions to the completion of the Transaction will not be satisfied or waived, that the Transaction will otherwise not be completed or that the Portfolio will not perform or be integrated as expected, as well as the factors discussed under the heading "Risk Factors" in the Company's annual information form available at www.sedar.com. There can be no assurance that forward-looking statements will prove to be accurate as actual outcomes and results may differ materially from those expressed in these forward-looking statements.
