Canada NewsWire

NEW YORK , Feb. 8, 2021 /CNW/ -- (NASDAQ: MDCA) – MDC Partners Inc. ("MDC") today announced that it has filed a registration statement on Form S-4 (the "Registration Statement") with the U.S. Securities and Exchange Commission ("SEC") in connection with the previously announced combination of MDC's business (the "Proposed Transaction") with certain operating businesses of Stagwell Media LP ("Stagwell"). Attached hereto is the letter to MDC's shareholders from Irwin D. Simon , Lead Independent Director of MDC's Board of Directors (the "MDC Board") and Chair of a special committee of independent members of the MDC Board (the "Special Committee").

As previously announced, the combined company is poised to deliver meaningful shareholder value creation, accelerated growth and enhanced services to clients. In contrast to MDC continuing as a standalone company, the highly compelling Proposed Transaction will create a leading marketing services company, with enhanced global scale and broadened premium capabilities.

The Proposed Transaction was approved by the MDC Board (with Mark Penn , Charlene Barshefsky and Bradley Gross abstaining from voting on, or from participating in any deliberations with respect to, the Proposed Transaction) following the affirmative recommendation by the Special Committee and, subject to approval by MDC shareholders, receipt of required regulatory approvals and other customary and negotiated closing conditions, is expected to close in the first half of calendar year 2021.

As further described in the Registration Statement , on a pro forma basis, without giving effect to any conversion of outstanding preference shares of MDC, it is anticipated that the existing holders of MDC's Class A common shares (including Stagwell) and Class B Common shares would receive approximately 26% of the common equity of the combined company, and Stagwell would receive share consideration equal to 74% of the common equity of the combined company.

While the Registration Statement has not yet been declared effective and the information contained therein is subject to change, the Registration Statement provides important information about the Proposed Transaction. Specifically, the Registration Statement includes information related to Stagwell's reporting segments, market strategy and historical consolidated financial data, along with unaudited pro forma combined financials for the combined company. Once the Registration Statement has been declared effective by the SEC, the final joint proxy statement/prospectus (the "Proxy Statement/Prospectus") contained in the Registration Statement will be mailed to shareholders of MDC prior to the shareholder vote on the Proposed Transaction.

[To be dated the date of effectiveness of S-4 registration.], 2021

Dear Shareholder:

The board of directors (the " MDC Board ") of MDC Partners Inc. (" MDC " or " MDC Canada ") cordially invites you to attend a special meeting (the " Meeting ") of its shareholders (the " MDC Canada Shareholders ") to be held virtually at [ ] [a.m./p.m.] on [ ], 2021, or at any adjournment or postponement thereof.

As previously announced, on December 21, 2020 , following the unanimous recommendation of a special committee of independent members of the MDC Board (the " MDC Special Committee ") and the subsequent approval by the MDC Board (other than Mark Penn , Charlene Barshefsky and Bradley Gross (collectively, the " Interested Directors ") who abstained from voting on, or participating in any deliberations with respect to, the Proposed Transactions), MDC Canada and Stagwell Media LP (" Stagwell ") entered into a transaction agreement (the " Transaction Agreement "), providing for, among other things, the redomiciliation (the " Redomiciliation ") of MDC Canada from the federal jurisdiction of Canada to the State of Delaware (from and after the Redomiciliation, " MDC Delaware ") and the subsequent combination (the " Business Combination ") of MDC's business with the business of the subsidiaries of Stagwell that own and operate a portfolio of marketing services companies (the " Stagwell Subject Entities "). The Redomiciliation, the Business Combination, and a series of related transactions are referred to herein as the " Proposed Transactions ", and following the Business Combination, the combined company shall be referred to herein as the " Combined Company ".

On a pro forma basis (and (i) without giving effect to any conversion of MDC's outstanding preference shares and (ii) including unvested restricted stock and restricted stock units of MDC), following completion of the Proposed Transactions, it is anticipated that the existing holders of class A subordinate voting shares of MDC Canada (the " MDC Canada Class A Common Shares ") and class B multiple voting shares of MDC Canada (the " MDC Canada Class B Common Shares ", and together with the MDC Canada Class A Common Shares, the " MDC Canada Common Shares ") (including Stagwell) will own approximately 26% of the common equity of the Combined Company, and Stagwell would be issued an amount of shares of Class C common stock of the Combined Company equivalent to approximately 74% of the voting rights of the Combined Company (with the percentage of the equity interests in the Combined Company owned by Stagwell being adjusted downwards if certain restructuring transactions are not completed prior to the consummation of the Proposed Transactions) and exchangeable, together with the Stagwell OpCo Units (as defined below), for shares of Class A common stock of the Combined Company on a one-for-one basis at Stagwell's election following a six-month holding period, in each case subject to certain adjustments described in the accompanying proxy statement/prospectus.

The Combined Company will be poised to deliver meaningful shareholder value creation, accelerated growth and enhanced services to clients. In contrast to MDC Canada continuing as a standalone company, the highly compelling combination creates a leading marketing services company, with enhanced global scale and broadened capabilities:

Enhanced Shareholder Value . The Combined Company will accelerate growth and enhance shareholder value. The Combined Company will offer a comprehensive suite of complementary marketing and communications services to clients, significantly expanding in the areas of high-growth digital services and expertise as well as substantial new capabilities across several disciplines and geographies, as compared to MDC as a standalone entity.

Estimated Cost Synergies . Due to certain synergies described in the accompanying proxy statement/prospectus under " The Proposed Transactions - Estimated Cost Synergies ," the Combined Company is expected to achieve certain cost synergies and incur run-rate savings of approximately $30 million over time, with approximately 90% of such savings expected to be realized within twenty-four months following the consummation of the Proposed Transactions.

Lower Pro Forma Leverage . The Combined Company will have an improved credit profile, decreasing its consolidated net leverage ratio from 4.2x to 3.4x, after giving full effect to the expected run-rate operational synergies.

Enhanced Scale . The Combined Company will be a top ten global integrated marketing services company. The Combined Company will have an expanded global scale, operating in 23 countries, and expanded media and data operations, managing $4.4 billion in media spend.

Enhanced Growth Opportunities . The Combined Company will have a target of 5%+ annual organic growth, driven by 10 – 15% digital marketing growth and complementary capabilities, and a target of 9% + total annual revenue growth including new products and acquisitions. The Combined Company will more than triple its concentration of high growth digital offerings, with 32% of its business anticipated to be in the digital services sector. It is anticipated that the Combined Company will generate over $200 million of pro forma cash in 2021. The Combined Company will target growth to $3 billion+ in revenue in 2025, including acquisitions, organic growth and new products. In addition, the Combined Company will seek to develop new revenue streams by expanding its combined digital and technology products portfolios.

The Transaction Agreement also includes several minority protection rights and corporate governance protections, including:

Three Continuing Independent Directors . Three individuals who currently serve as independent directors of MDC (the " Continuing Independent Directors ") will serve as directors on the board of directors of the Combined Company (the " Combined Company Board ") and the Combined Company has agreed to cause such directors to be nominated at the Combined Company's next two annual meetings following completion of the Proposed Transactions. Mr. Penn will continue as a director and Stagwell has the right, pursuant to the Transaction Agreement, to nominate four directors (and Stagwell has informed MDC that it expects to nominate at least two independent directors) and an affiliate of Goldman Sachs & Co. LLC will have the right to nominate one director to serve on the Combined Company Board.

Continuing Independent Directors will Comprise Audit Committee . The Combined Company's audit committee will be comprised exclusively of the Continuing Independent Directors.

Restrictions on Related Party Transactions . During the period following the Proposed Transactions for so long as (i) Stagwell beneficially owns more than 10% of the then-issued and outstanding voting securities of the Combined Company, (ii) Stagwell has nominated directors constituting a majority of the Combined Company Board, or (iii) Stagwell has the contractual right to appoint a majority of the Combined Company Board (the " Restricted Period "), the Transaction Agreement generally will prohibit the Combined Company from entering into certain related party transactions without the approval of a majority of the independent directors serving on the Combined Company Board.

"Majority of the Minority" Voting Rights . During the Restricted Period, the Transaction Agreement will further generally prohibit the Combined Company from entering into any proposed business combinations involving Stagwell or its affiliates without (A) the approval of the Combined Company stockholders representing a "majority of the minority" of the voting power of the Combined Company and (B) the creation of a special committee of independent directors with authority similar to that of the MDC Special Committee.

At the Meeting, you will be asked to consider and approve six proposals (the " Proposals "):

Proposal 1 : the approval of the Redomiciliation (the " Redomiciliation Proposal ");

Proposal 2 : the approval of each of the Proposed Transactions, other than the Redomiciliation (the " Business Combination Proposal "), including the following:

The MDC Reorganization . Following the Redomiciliation, MDC Delaware will merge with one of its indirect wholly-owned subsidiaries (the " MDC Merger "), with MDC Delaware (from and after the MDC Merger, " OpCo ") surviving as a direct subsidiary of a newly-formed, NASDAQ-listed Delaware Corporation (" New MDC "). Following the MDC Merger, OpCo will convert into a limited liability company (together with the MDC Merger, the " MDC Reorganization ") that will hold MDC's operating assets.

The Contributions . At the closing of the Proposed Transactions, Stagwell will contribute (i) the issued and outstanding equity interest of Stagwell Marketing Group Holdings LLC, the direct or indirect owner of the Stagwell Subject Entities other than SMGH, to OpCo in exchange for 216,250,000 common membership interests of OpCo (the " Stagwell OpCo Units "), and (ii) an aggregate amount of cash equal to $100 in to New MDC in exchange for 216,250,000 shares of a new Class C series of voting-only common stock of New MDC (the " Stagwell Issuance ").

Proposal 3 : the granting of the proxy in relation to the common shares of MDC Delaware (the " MDC Delaware Common Shares ") and Series 6 convertible preference shares of MDC Delaware (the " MDC Delaware Series 6 Shares ") to be held by such MDC Canada Shareholder immediately following the consummation of the Redomiciliation, as applicable to each of MDC and The Stagwell Group LLC (each in such capacity, a " Proxyholder ") whereby each Proxyholder, acting singly, with respect to and on behalf of the holders of MDC Delaware Common Shares and the MDC Delaware Series 6 Shares that voted in favor of this proposal, may vote in favor of, or consent to, the approval and adoption of the Transaction Agreement and the Proposed Transactions, including the MDC Reorganization (collectively, the " MDC Delaware Consent "), which MDC Delaware Proxy (A) shall survive until the earlier of (1) the termination of the Transaction Agreement in accordance with its terms and (2) the effectiveness of the MDC Delaware Consent and (B) with respect to MDC, shall be granted conditional on MDC, in its capacity as Proxyholder, irrevocably committing to vote such MDC Delaware Common Shares and MDC Delaware Series 6 Shares to approve and adopt the Transaction Agreement and the Proposed Transactions, including the MDC Reorganization (the " MDC Delaware Proxy Proposal ");

Proposal 4 : in accordance with NASDAQ Listing Rule 5635, the approval of the issuance of the MDC Delaware Series 6 Shares, as described in Proposal 3 (the " Series 6 Supervoting Proposal ");

Proposal 5 : in accordance with NASDAQ Listing Rule 5635, the Stagwell Issuance, as described in Proposal 2 (the " Stagwell Issuance Proposal "); and

Proposal 6 : the non-binding advisory approval of the compensation that may be paid or become payable to MDC's named executive officers in connection with the Proposed Transactions (the " Compensation Proposal ").

The Redomiciliation Proposal and the Business Combination Proposal are subject to approval by both (i) at least two-thirds of the total votes cast on such Proposals, and (ii) at least a "majority of the minority" of the votes cast by each class on such Proposals ( i.e. , a majority, excluding the votes of interested shareholders required to be excluded by applicable securities laws), and the consummation of each of the Proposals other than the Compensation Proposal (all such Proposals, collectively, the " Transaction Proposals ") is conditioned on the approval by the requisite MDC Canada Shareholder threshold of the other Transaction Proposals, such that MDC will only effect the Proposed Transactions if the MDC Canada Shareholders approve each of the Transaction Proposals by the required threshold.

Acting upon the unanimous recommendation of the MDC Special Committee, the MDC Board (with the Interested Directors abstaining) unanimously recommends that the MDC Canada Shareholders vote " FOR " each of the Transaction Proposals. Additionally, the MDC Board (with the Interested Directors abstaining) unanimously recommends the MDC Canada Shareholders vote " FOR " the Compensation Proposal.

You are encouraged to read the accompanying document carefully. In particular, you should read the " Risk Factors " section beginning on page 50 of the accompanying proxy statement/prospectus for a discussion of the risks you should consider in evaluating the Proposed Transactions and how they will affect you.

Your vote is very important regardless of the number of MDC Canada Common Shares or preference shares of MDC Canada (collectively, the "MDC Canada Shares") that you own . Whether or not you expect to attend virtually, you should authorize a proxyholder to vote your MDC Canada Shares as promptly as possible so that your MDC Canada Shares may be represented and voted at the Meeting. Enclosed with this letter is the Notice of Special Meeting and Proxy Statement/Prospectus and a form of proxy or voting instruction form.

Due to the continuing public health impact of the novel coronavirus pandemic (COVID-19) and to support the health and well-being of our employees and shareholders, MDC Canada has decided that the Meeting will be held solely by means of remote communication as a virtual meeting. A virtual Meeting enables registered holders of MDC Canada Shares and duly appointed proxyholders to listen to the Meeting, ask questions and receive answers online, and vote online at [ ] by clicking "I have a control number" and then entering your unique 13-digit control number located on your form of proxy and the password "[ ]" (case-sensitive).
