Jeremy Andersen joined the firm in 2003.  His accounting background allowed him to begin work immediately reconstructing complex financial transactions and frauds by following transactions from their contractual inception, through the internal records, and to the audited financial statements and other representations made to investors.

Mr. Andersen is now a long-running, core member of multiple Quinn Emanuel teams where the firm was appointed lead or co-lead counsel in large antitrust, securities, and Commodity Exchange Act cases.  He has pursued such claims on behalf of institutional investors, insurance companies, and bankrupt estates, both in their individual capacity and as part of class actions.  Most of his cases have been against the world’s largest banks and auditing firms, meaning he is often going up against many of the world’s largest defense law firms at once.  He has had great success in doing so.  Mr. Andersen has been involved in multiple matters that secured around $100 million or more, including four in the past few years alone.  Overall, he has helped victims recover almost $4 billion in pending or approved settlements. 

Mr. Andersen continues to be a key part of big-ticket plaintiffs’ cases.  For instance, he was a core team member responsible for investigating and then drafting the complaint, and then defending it against a motion to dismiss, in a large matter alleging that there was a conspiracy to rig the operation of an FX trading platform.  In 2023, the court upheld all of the core claims, allowing the case into discovery.  By way of another example, he was one of only two attorneys that were part of the firm’s formation of a large group of “opt-out” plaintiffs regarding manipulation of trading “spreads,” who then also stayed with the case for its entire duration.  After many years spent forming the historically large opt-out group and then litigating the matter, the case was successfully resolved in 2023. 

Additionally, Mr. Andersen has a diverse practice outside of representing plaintiffs in the financial space.  For instance, he was a key team member when Quinn Emanuel was appointed co-lead counsel in an antitrust case alleging monopolistic behavior in the sale of pesticides in 2023. He has also handled multiple disputes involving private equity investors. Mr. Andersen additionally operates on the defense side of the “v.,” recently for instance in a sprawling set of MDL antitrust cases regarding the sale of fed cattle and processed beef.

On his teams, he is often the primary author or editor of key filings, from the initial complaint, through the dismissal stage, and into discovery and expert fights.  Those roles also mean he helps guide the overall strategy for the cases.  In all of these tasks, Mr. Andersen often serves as the “translator” for the firm and the Court—turning incredibly complex data, expert analysis, and concepts into winning strategies and plain-English submissions.

Finally, he not only successfully litigates large class actions, but makes sure any related settlements get approved.  For instance, in a class action involving manipulation of the ISDAfix interest-rate benchmark, Mr. Andersen not only was a key driver of that complex case generally, but also the main architect and defender of a multi-pronged plan of how to distribute $500 million in settlement proceeds to a large and sophisticated group of class members.  Similarly, he was key in bringing an antitrust and CEA class action alleging a benchmark price for gold was rigged.  After $152 million in settlements were reached, Mr. Andersen successfully secured their approval, despite objections filed to both the settlement terms and the plans of allocation.  In 2023, he is working on the approval process for $580 million in settlements relating to allegations of antitrust violations in the stock-loan industry.
