Nicole Allen is widely recognized for her work defending Fortune 500 companies in high-profile class action cases alleging market manipulation, securities and commodities fraud, and antitrust claims worth billions of dollars. Nicole also has extensive experience representing companies in high-profile investigations, including criminal matters initiated by the Department of Justice.

She represents clients in a variety of industries, with a particular emphasis on energy and agricultural companies, having defended some of the largest energy and agricultural companies in the world in matters against the Department of Justice, Securities and Exchange Commission, Commodity Futures Trading Commission, Internal Revenue Service, and in private litigation. She has also defended broker-dealers, investment advisors, energy companies, and multi-national agricultural and food and beverage companies in cases involving market manipulation, securities fraud, bribery, antitrust violations, and breach of fiduciary duty and breach of contract claims.

Nicole recently represented the nation’s largest utility in a Department of Justice criminal investigation involving allegations of bribery, resolving the matter and winning dismissal of related class action cases brought in federal and state court. She also won dismissal of a securities class action involving allegations of bribery and corruption on behalf of a large Ohio utility.

Prior to joining Jenner & Block, Nicole worked for DaimlerChrysler AG in Corporate Union Relations. She represented DaimlerChrysler in labor contract negotiations with the United Auto Workers, and was responsible for investigating and responding to charges filed with the National Labor Relations Board and Equal Employment Opportunity Commission.
