The Company maintains office space in North America, Europe, Asia, South America, the Middle East, Africa, and Australia. These spaces are primarily used for office and administrative purposes by the Company’s employees in performing professional services. These office spaces are in suitable and well-maintained condition for Stagwell’s current operations.

In addition, leases related to the Company’s non-U.S. businesses are denominated in currencies other than U.S. dollars and are therefore subject to changes in foreign exchange rates.

The story

Founded by Miles Nadal in 1980.1

MDC Partners was founded as Multi Discipline Communications in 1980 in Toronto by Miles Nadal. The company held an IPO on October 16, 1987.

The company operated two divisions in the 1990s: Marketing and Communications and Secure Transaction Products, which included the production of checks, credit and debit cards, tickets, and stamps. Toward the end of the 1990s, MDC concentrated on growing its marketing and communications business. It continued to expand into the United States, surpassing CAD$1 billion in revenue in 2000 through acquisitions and organic growth.

In 2001, MDC formed its first partnership with the agency Crispin Porter + Bogusky.

In January 2004, the company changed its name to MDC Partners Inc.

In 2008, MDC became the first advertising company to build a capability designed for automated, or programmatic media trading, with the formation of Varick Media Management.

The company acquired Anomaly in 2010 and 72andSunny in 2011.

On July 21, 2015, Miles Nadal announced his resignation as CEO in response to an investigation by the U.S. Securities and Exchange Commission regarding executive pay and accounting practices. Nadal agreed to pay back $1.9 million in expenses and $10.6 million in salary and bonuses. He did not receive any severance or compensation for resigning. Chief accounting officer Michael Sabatino also announced his resignation and would reportedly repay $208,000 in bonuses. MDC's presiding director of the board, Scott Kauffman, succeeded Miles Nadal as chairman and CEO.

In December 2015, the company ranked 8th in Advertising Age’s global ranking of Agency Networks, by cumulative award wins. In June 2016, MDC announced the first acquisition under Kauffman of Swedish creative agency Forsman & Bodenfors, forming a strategic partnership with sister agency CP+B.

In April 2018, MDC acquired a 51% majority stake in digital creative agency Instrument for an undisclosed amount.

In March 2019, Mark Penn was named CEO of MDC Partners, and The Stagwell Group invested $100 million in the company.

Company overview

MDC Partners is a global advertising holding company that invests in agency partners in the areas of advertising, marketing, media management, technology, analytics and consumer insights, direct marketing, and strategic consulting. The company is headquartered in New York City and also operates a corporate office in Toronto, where it was founded. It earned approximately US$1.33 billion in revenue 2015.

MDC typically invests in creative and digital firms. Historically, it invested in agencies during times when similar companies have scaled back on acquisitions. While the company has mainly invested in North American small to mid-sized agencies, it extended onto new global markets in the 2010s. As of 2015, 9% of the company's revenue came from outside North America.

MDC does not generally acquire agencies outright, but instead partners with agency management by acquiring a 51 to 80 percent initial stake. Instead of integrating the firms, acquired agencies continue to manage their own day-to-day operations. MDC provides support to the agencies in which it has invested including business strategy and financial resources. It operates a Strategic Resources Group, which supports the development of partner agencies. In 2004, Adweek called the company an "anti-holding company".

Major holdings include over 50 advertising and marketing firms:

Risk factors and legal proceedings

The risks MDC Partners names in Item 1A of its 10-K filed Mar 13, 2026: 38 risks under these headings, as written.17

  • Risks Related to Our Business and Industry
  • Our revenues are highly susceptible to declines as a result of unfavorable economic conditions.
  • Our business depends on generating and maintaining ongoing, profitable client demand for our services and solutions.
  • Our business could be adversely affected if we fail to retain our existing clients.
  • We face significant competition.
  • Our success depends in part on our ability to adapt to ongoing changes in technology and offerings.
  • We are making investments in new product offerings and technologies that are inherently risky.
  • We are subject to risks related to our use of AI, including generative AI.
  • Our international operations are exposed to a number of risks.
  • We are exposed to the risk of client defaults.
  • We are impacted by geopolitical events, international hostilities, terrorist attacks and natural disasters.
  • We are impacted by seasonal fluctuations in marketing, research, communications and advertising activity.
The other 27 risks
  • Risks Related to Strategic Transactions
  • We may not realize the expected benefits from strategic transactions.
  • Strategic transactions may result in dilution to our stockholders and consume resources that are necessary to sustain our business.
  • Risks Related to Our Employees and Human Resources
  • Our business is highly dependent on the services of Mark Penn, our CEO and Chairman.
  • Our business is dependent on our ability to keep our supply of skills and resources in balance with client demand.
  • Risks Related to Data Privacy and Cybersecurity
  • We face legal, reputational and financial risks from any failure to protect client data from security incidents or cyberattacks.
  • We are subject to extensive data privacy laws and regulations.
  • Risks Related to Litigation and Regulation
  • Litigation, investigations or other legal proceedings could expose us to significant liabilities and have a negative impact on our reputation or business.
  • We are subject to industry regulations and other legal or reputational risks that could restrict our activities or negatively impact our performance or financial condition.
  • We are subject to export restrictions, economic sanctions, the FCPA, and similar anti-corruption laws.
  • Risks Related to Intellectual Property
  • Our business operations could suffer if we fail to adequately protect and enforce our intellectual property and other proprietary rights.
  • We may be subject to an intellectual property infringement or misappropriation claim.
  • Our products and services use open source software.
  • Risks Related to Our Capital Structure and Financing
  • Our substantial indebtedness could adversely affect our ability to raise additional capital to fund our operations, limit our ability to react to changes in the economy or in our industry, expose us to interest rate risk to the extent of our variable rate debt, and prevent us from meeting our obligations under our indebtedness.
  • We may need additional capital in the future, which may not be available to us. The raising of any additional capital may dilute holders’ ownership percentage in our stock.
  • If our available liquidity is insufficient, our financial condition could be adversely affected and we may be unable to fund contingent deferred acquisition liabilities, and any put options if exercised.
  • Our Up-C structure places significant limitations on our cash flow and, accordingly, we depend on distributions from OpCo to pay our taxes and expenses, including payments under the Tax Receivables Agreement.
  • Our Tax Receivables Agreement with Stagwell Media requires us to make cash payments to Stagwell Media (or its assignees) in respect of certain tax benefits to which we have become entitled, and we expect the payments we are required to make to be substantial, may be required to be made prior to the time that we recognize any associated tax benefits and may make our company a less attractive target to potential acquirers.
  • Risks Related to Accounting and Tax Issues
  • Our results of operations are subject to foreign currency exchange fluctuation risks.
  • Our goodwill, intangible assets and right-of-use lease assets may become impaired.
  • We previously identified and remediated material weaknesses in our internal control over financial reporting and there can be no assurance that additional material weaknesses will not be identified in the future.
  • Our disclosure controls and procedures and internal controls may not prevent or detect all errors or acts of fraud.
  • Our judgments or estimates relating to our critical accounting policies are based on assumptions that could change or be incorrect.
  • We may be subject to adverse tax consequences.
  • We may face material adverse tax consequences resulting from the Transactions in Canada, the United States or other jurisdictions.
  • Risks Related to Ownership of Our Class A Common Stock and Our Status as a Public Company
  • Our stock price may be volatile.
  • If our operating and financial performance in any given period does not meet any guidance that we provide to the public, the market price for our Class A Common Stock may decline.
  • A significant portion of our Class A Common Stock is held by our affiliates and these shares of Class A Common Stock may be sold into the market in the future, or should allow the affiliates to control decisions requiring stockholder approval, either of which could negatively affect our stock price.

Legal proceedings

In the ordinary course of business, we are involved in various legal proceedings. We do not currently expect that these proceedings will have a material adverse effect on our results of operations, cash flows or financial position.
