Mack-Cali Comments on ISS and Glass Lewis Reports

Urges Shareholders to Protect the Value of Their Investment by Voting "FOR" ALL of Mack-Cali's Independent, Highly Qualified and Experienced Nominees on the WHITE Proxy Card

JERSEY CITY, N.J. – Mack-Cali Realty Corporation (NYSE: CLI) ("Mack-Cali" or the "Company") today issued the following statement in response to the reports issued by Institutional Shareholder Services (“ISS”) and Glass Lewis & Co. (“Glass Lewis”) in connection with the Company’s Annual Meeting of Stockholders scheduled for June 10, 2020 (the “Annual Meeting”).

Commenting on the reports, Mack-Cali issued the following statement:

The Mack-Cali Board continues to urge shareholders to vote on the WHITE proxy card “FOR” ALL ELEVEN of the Company’s highly qualified and experienced director nominees in connection with the Company’s Annual Meeting. In addition to the Company's CEO, Michael J. DeMarco, and five incumbent independent directors – Alan S. Bernikow, Lisa Myers, Laura Pomerantz, Rebecca Robertson and Dr. Irvin D. Reid – the Company’s slate of nominees includes five new highly qualified, independent nominees: Z. Jamie Behar, Michael Berman, Howard Roth, Gail Steinel and Lee Wielansky.

Mack-Cali strongly disagrees with ISS’ and Glass Lewis’s recommendations that shareholders vote on Bow Street Special Opportunities Fund XV, LP and certain of its affiliates’ (“Bow Street”) gold proxy card. Doing so would effectively give control of the Board to a 4.5% shareholder and would also likely result in the removal of the CEO during an unprecedented time for the world and real-estate industry. Recognizing that this outcome would be detrimental to the Company and its shareholders, Glass Lewis has recommended that shareholders withhold support for several of Bow Street’s nominees. Specifically, Glass Lewis noted Bow Street’s many potential conflicts of interest and recommended that shareholders oppose efforts by Bow Street to gain control of the Mack-Cali Board of Directors. The Glass Lewis report says: “…we do not support majority board turnover at this time, particularly given Bow Street’s previously established interest in participating in an acquisition of [Mack-Cali]...”¹

While Mack-Cali believes ISS erred in recommending for the dissident slate, ISS did note that Mack-Cali has taken substantial steps to transform its portfolio, and acknowledged the incremental steps the Company has taken to enhance its corporate governance. ISS also recognized the risk involved with a CEO transition at this critical time in the Company’s transformation strategy.

Overall, however, we are disappointed that ISS and Glass Lewis largely failed to recognize the significant Board and governance enhancements Mack-Cali has made over the last year and the Company’s progress on its portfolio transformation to position Mack-Cali to maximize shareholder value. Instead, ISS and Glass Lewis seem to have been deceived by Bow Street’s misinformation and misleading commentary regarding our Board, governance structure and the merits of our strategy.

Their analysis also appears to miss that with important and influential committee roles, the Bow Street directors elected in 2019 were well positioned to share their perspectives. Their unanimous votes in alignment with the Board on every matter over the course of the year is compelling proof that the Board has been making the right choices on behalf of shareholders, and undermines Bow Street’s deceptive claims about how the Board functions.

¹ Permission to use quotations neither sought nor obtained.

Today’s Mack-Cali Board is not the Mack-Cali Board of years past. The Board comprises highly-qualified independent directors with the skills and experience to oversee the successful execution of Mack-Cali’s transformation strategy and a strategic alternatives process to identify the path to maximize value. The Board is committed to engaging with shareholders and taking decisive action to respond to feedback, as evidenced by the significant governance enhancements the Board made following Mack-Cali’s 2019 Annual Meeting. Following shareholders’ feedback, the Board amended the Company’s charter to opt out of certain Maryland Unsolicited Takeover Act (“MUTA”) provisions, eliminating the Board’s ability to re-classify without shareholders’ approval. The Board also secured agreement from the Mack family to rescind its contractual right to nominate three directors to the Board. Additionally, we committed to appoint an independent Board Chair after the Board’s current Chairman, William L. Mack, retires at the upcoming Annual Meeting.

Moreover, we have continued to refresh the composition of the Mack-Cali Board of Directors, nominating five new, highly qualified independent candidates for election at this year’s Annual Meeting. If the Mack-Cali Board’s eleven nominees are elected at the Annual Meeting:

Our five new highly qualified nominees are: Z. Jamie Behar, Michael Berman, Howard Roth, Gail Steinel and Lee Wielansky. All of these nominees were selected as a result of a rigorous and comprehensive search process, and all of them are fully independent of the Company’s management, any incumbent Board members and the Mack family.

We are confident that the Mack-Cali nominees are the right individuals to oversee the successful execution of our portfolio transformation strategy. Over the past five years, Mr. DeMarco and the management team have implemented a strategy to successfully overhaul the Company’s legacy portfolio of flex and suburban office assets in low growth markets through the disposition of more than $2.5 billion of non-core assets. Recognizing powerful secular urbanization trends, and the benefits of proximity and affordability presented by the New Jersey waterfront, Mack-Cali has pivoted its portfolio from depreciating suburban office assets to appreciating waterfront office assets and residential development property to create a forward-looking “live, work, play” community.

Through this portfolio transformation strategy, Mack-Cali has been transformed into an owner of higher-quality office buildings and higher-value multi-family properties focused around the New Jersey Waterfront. With this massive effort near completion, the Company has a simplified portfolio that offers growth opportunities, a more sustainable and higher quality cash flow and lower recurring capital requirements.

As we pursue the final step in our portfolio transformation, the Mack-Cali Board looks forward to continuing to engage with shareholders and taking action based on their feedback. We are confident in the path ahead for Mack-Cali and that the steps we are taking will position Mack-Cali to run a strategic alternatives process with the goal of maximizing shareholder value in the near-term.

We believe voting on Bow Street’s gold proxy card would derail the progress we have made on the transformation strategy and prevent Mack-Cali from realizing its full potential for the benefits of all shareholders. We continue to believe that Bow Street has never been transparent about its objectives and that Bow Street’s communications to date have demonstrated that it has no substantive plan for the Company beyond the removal of Mr. DeMarco as CEO, which we believe would be detrimental. Moreover, we believe that the conduct and conflicts of interest of the Bow Street nominees raises critical questions as to whether they can effectively serve as independent stewards of shareholders’ capital. By nominating the Bow Street’s nominees to the Mack-Cali Board, shareholders will be giving Bow Street the green light to advance its own, self-interested agenda at the expense of all other Mack-Cali shareholders.

We strongly recommend Mack-Cali shareholders vote on the WHITE proxy “FOR” ALL ELEVEN of Mack-Cali’s independent, highly qualified and experienced director nominees to help us continue our work to deliver shareholders the true value of their investment.
