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.
Experience
- Defended the officers of a prominent Israeli manufacturing company against securities claims that the officers knowingly misrepresented the performance of a business unit accused of bribery. Achieved complete pleadings-stage dismissal with prejudice of all claims, which sought over $1 billion in damages.
- Defended a national physical therapy clinic operator against a putative securities class action that alleged the company's accounting restatement resulted from a knowing mischaracterization of noncontrolling interests in individual clinics. The court dismissed all the allegations with prejudice, finding plaintiffs had alleged no facts from which fraudulent intent could be inferred.
- Defended a well-known technology company and its directors against consolidated lawsuits that claimed the defendants omitted material information from a proxy statement filed in connection with its merger with another well-known company. Negotiated a limited disclosure-based settlement of all claims before the scheduled stockholder vote, which occurred without incident.
- After another law firm failed to secure a pleadings-stage dismissal, assumed the defense of an international bank accused of misleading investors about the value of its bonds, in alleged violation of the Securities Exchange Act. Following aggressive fact and expert discovery, obtained complete victory on summary judgment and subsequent affirmance in the Second Circuit Court of Appeals.
- Defended a pharmaceutical company and its officers against a putative securities class action lawsuit alleging that defendants mischaracterized the likelihood that the company would receive FDA approval to sell its leading drug candidate.

- Defended the world's largest cannabis company in a wide-ranging Delaware books and records lawsuit. Obtained complete dismissal in a ruling that judicially construed the phrase "business day" for the first time in Delaware history.
