Jason Vigna has extensive experience representing clients in more than seventy complex securities, commercial and corporate governance matters in trial and appellate courts throughout the country and before the SEC. He has helped technology companies, life sciences companies, asset management firms and other sophisticated businesses -- and their officers and directors -- successfully resolve disputes involving a wide variety of stockholder- and fraud-related claims.
Jason has not only worked on some of the largest securities fraud cases in history (including Worldcom and the "IPO laddering" cases), but also the defense of nearly a dozen small or mid-sized life sciences companies wrongly accused of misleading investors. His track record includes the successful defense of an asset management company in dozens of class, derivative, bankruptcy and individual actions arising out of hedge fund investments made with Bernard Madoff; the successful defense of the former CEO and the former general counsel of the then-largest broker on the Chicago Mercantile Exchange in consolidated actions arising out of the broker’s collapse; and representation of the special litigation committee of the then-largest insurance company in the world in an investigation of allegations that senior officers breached fiduciary duties in connection with a $4 billion accounting restatement.
Jason's current clients include a major European private equity fund, a cryptocurrency exchange and a large real estate development company. He is ranked by Chambers USA, has been a preferred securities defense counsel panel member for multiple insurance companies and brokers and, in 2022, 2019 and 2017, was a Legal 500 "Recommended Attorney." Published client testimonials call Jason "[c]reative, dedicated, smart and efficient," "always available," “detail-oriented," "a really good creative writer and thinker in the space," and "an excellent attorney with a deep understanding of securities litigation and [an] appreciation for litigation strategy" "[whose] advice blends the legal, commercial and practical."
Prior to joining Mintz, Jason was a partner at another large law firm, where he helped clients resolve disputes involving federal and state stockholder- and fraud-related statutes, including the Securities Exchange Act of 1934, the Securities Act of 1933, the Racketeering Influenced and Corrupt Organizations (RICO) Act and the Delaware General Corporation Law. He also represented clients in commercial litigation and fights over the control of closely-held companies.
In addition to U.S. clients, Jason has represented numerous foreign companies, including several from Israel and others from Bermuda, Canada, China, England, Germany, Ireland, Italy, Kazakhstan, Luxembourg and Singapore.
Before entering private practice, Jason clerked for the Honorable J.P. Stadtmueller of the US District Court for the Eastern District of Wisconsin.
