    Deals and strategic moves:

    MDC Partners:

    MDC Partners' board in December 2020 approved a merger agreement with Stagwell in a deal that had been anticipated since Stagwell made its initial merger proposal in June 2020.

    Stagwell, already MDC's biggest shareholder, would own 79% of the combined company under the deal. The deal was subject to various approvals including approval by MDC shareholders. Stagwell and MDC hoped to complete the deal in the first half of 2021.

    Stagwell in March 2019 invested $100 million in MDC, an agency company, by purchasing $50 million in MDC common shares and $50 million in non-voting convertible preference shares. As part of the deal, Penn, Stagwell's president and managing partner, joined MDC as CEO and a board member.

    Following the 2019 transaction, Stagwell owned about 19.5% of MDC outstanding common stock. Assuming full conversion of the preference shares into MDC common stock, Stagwell would own about 29.2% of MDC outstanding common stock. Assuming conversion of both Stagwell preference shares and outstanding Goldman Sachs preference shares issued in 2017, Stagwell would own about 24.8% of MDC outstanding common stock.

    Assuming full conversion of the preference shares into MDC common stock, Stagwell controlled 29.4% of MDC outstanding common stock as of March 31, 2020.

    Stagwell's investment came after MDC in September 2018 announced the planned exit of Chairman-CEO Scott Kauffman; a search for a new CEO; and MDC's "intention to explore and evaluate potential strategic alternatives, which may result in, among other things, the possible sale of the company." In announcing the 2019 deal with Stagwell, MDC said: "This represents the conclusion of the strategic review process and CEO search."

    Penn became MDC's CEO on March 18, 2019, and was named chairman effective April 18, 2019.
