• Presentation reiterates compelling rationale for the acquisition plan set out in the management information circular filed by Cominar November 24, 2021, as well as numerous key considerations that make remaining as a publicly traded REIT a riskier proposition for Unitholders.
• Offer by Canderel-led consortium represents a 63.2% premium to the closing Unit price on September 15, 2020, the last trading day prior to the announcement of Cominar's Strategic Review Process and a 16.3% premium to Cominar's 20-day volume-weighted average price per Unit on the TSX for the period ending on October 22, 2021, the last trading day prior to the announcement of the Arrangement.
• Following a comprehensive 13-month Strategic Review Process, the Arrangement has unanimous support of both the Board of Trustees of Cominar and the Special Committee, comprised of independent trustees, and represents the most favourable outcome from Cominar's Strategic Review Process for Cominar, its Unitholders and other stakeholders.
• Proxy voting deadline is 11:00 a.m. (Montréal time) on December 17, 2021

QUÉBEC CITY, Dec. 6, 2021 /CNW Telbec/ - Cominar Real Estate Investment Trust ("Cominar" or the "REIT") (TSX: CUF.UN) today announced that it has issued a presentation for holders (the "Unitholders") of units of Cominar (the "Units") reiterating the compelling reasons to vote FOR the proposed arrangement (the "Arrangement") pursuant to which all Units would be acquired for $11.75 per Unit in cash by a consortium led by an affiliate of Canderel Management Inc. ("Canderel"), providing certain value and immediate liquidity to Unitholders.

The presentation reiterates key information for Unitholders set out in the management information circular filed by Cominar on November 24, 2021 (the "Circular"). The contents of the presentation are qualified in their entirety by the Circular, and Unitholders are urged to carefully review the Circular to fully understand the numerous reasons to support the Arrangement and then vote FOR the Arrangement prior to the proxy voting deadline of 11:00 a.m. (Montréal time) on December 17, 2021. The Circular is available at https://www.cominar.com/en/investors/publications/ and under Cominar's profile on SEDAR at www.sedar.com.

Under the terms of the Arrangement, the consortium led by Canderel, a leading Canadian developer and manager, and which also includes FrontFour Capital Group LLC ("FrontFour"), Artis Real Estate Investment Trust ("Artis") and partnerships managed by the Sandpiper Group ("Sandpiper"), with Koch Real Estate Investments, LLC ("KREI") and Artis providing preferred equity, would acquire the Units. In addition, under the Arrangement, Groupe Mach Acquisition Inc. and Blackstone would acquire certain assets of the REIT in off-take transactions.

The presentation, which is available at www.cominar.com, reiterates the structure and rationale for the Arrangement and details the comprehensive process and rigorous corporate governance practices that led to the Arrangement. The presentation also clearly explains the numerous considerations described in the Circular that make attempting to pursue a status quo plan as a publicly traded REIT a riskier proposition for Unitholders.

Key takeaways of the Arrangement include:

• The Arrangement represents the culmination of an extensive and thorough strategic review process diligently pursued over 13 months (the "Strategic Review Process");
• Broad set of alternatives reviewed including: (i) status quo; (ii) select asset sales aimed at enhancing the status quo; (iii) structural alternatives aimed at surfacing value from asset classes; and (iv) a sale of the entire REIT;
• The Arrangement provides compelling value to Unitholders, including certainty and immediate liquidity;
• The Arrangement represents the highest actionable proposal and is the result of arm's-length negotiations following a robust dual-track process;
• Desjardins Securities provided an independent valuation with a fair market value range of $11.00-$12.50, in addition to a fairness opinion, while National Bank Financial and BMO Capital Markets each separately provided a fairness opinion;
• The Arrangement represents the most favourable outcome from Cominar's Strategic Review Process for Cominar, its Unitholders and other stakeholders.

THERE ARE SIGNIFICANT CHALLENGES TO REMAINING A PUBLIC REIT

The Strategic Review Process was driven in large part by the structural challenges that Cominar faced in its operating environment prior to the COVID-19 pandemic, which has only exacerbated these challenges.

As part of the process, Cominar looked at options to maintain the status quo and continue as a publicly traded REIT. Due to a number of considerations, that path is challenging and riskier for Unitholders. Those considerations described in the Circular include:

• Cominar has the highest leverage level among Canadian REITs of a similar size;
• The REIT has significant debt maturities of more than $1 billion by the end of 2022;
• Cominar's liquidity is constrained by negative free cash flow and limited potential to increase the mortgages on its assets, Asset sales were considered as a way to enhance the status quo, but come with their own challenges, including significant leakage from factors such as tax, and A significant equity issuance may be required to right-size the REIT's debt levels and provide flexibility to pursue the REIT's status quo plan, which could result in significant unitholder dilution.

Furthermore,

• It would require considerable time, capital investments, and execution/market risks to potentially reduce the gap between Cominar's unit price and its IFRS Net Asset Value (NAV) over time or through an en bloc transaction;
• Unitholders should be aware that IFRS NAV is mainly based on appraisals that assume a stabilized level of operations for each property achieved over time, taken individually, under a private real estate market context with no consideration given to the broader financial situation of Cominar and the execution risks associated with achieving stabilized operations, its public market status as a diversified REIT and any potential breakup value and leakage including mortgage defeasance and property brokerage fees, or tax consequences, that could arise from attempting to sell assets individually at the IFRS NAV;
• The REIT continues to be impacted by exposure to the challenged brick-and-mortar retail sector, and there are uncertainties regarding structural changes in office and retail sectors further exacerbated by the COVID-19 pandemic;
• The structural challenges the REIT faces will remain even in a better economic environment, Cominar requires meaningful investments in key retail and office assets, and its industrial assets also require investment to maintain their income generating capabilities, and
• Meaningful investment would also be required to develop or redevelop assets.

These considerations, as well as more that are detailed in the presentation, limit the ability of the REIT to achieve its long-term objectives and meaningfully enhance the status quo. The value derived from the Arrangement is more favourable than what could have been realized through the continuation of the status quo.

Cominar Unitholders as of the close of business on November 10, 2021 (the "Record Date") are entitled to receive notice of, and to vote at, the special meeting of Unitholders to be virtually held on December 21, 2021, at 11:00 a.m. (Montréal time) (the "Meeting"). Only persons shown on the register of Unitholders at the close of business on that date, or their duly appointed proxyholders, will be entitled to attend the Meeting and vote on the Arrangement Resolution (as defined in the Circular). Each Unit entitled to be voted at the Meeting will entitle the holder thereof as the Record Date to one vote at the Meeting in respect of the Arrangement Resolution. For the Arrangement to proceed, the Arrangement Resolution must be approved by not less than two-thirds of the votes cast at the Meeting by Unitholders virtually present or represented by proxy and entitled to vote at the Meeting.

To be counted at the Meeting, proxies must be received by the REIT's transfer agent, Computershare Trust Company of Canada, at 100 University Avenue, 8th Floor, Toronto, Ontario  M5J 2Y1, Attention: Investor Services, Fax: [phone], not later than 11:00 a.m. (Montréal time) on December 17, 2021 (or no later than 48 hours, excluding Saturdays, Sundays and holidays, before any reconvened meeting if the Meeting is adjourned or postponed).

If Unitholders hold Units as an objecting beneficial owner through an intermediary such as a broker, investment dealer, bank, trust company, trustee, clearing agency (such as CDS) or other nominee holder, and received a voting instruction form from your intermediary or Broadridge Financial Solutions, Inc., they should follow the instructions provided to ensure their vote is counted at the Meeting.
