Ellen Jalkut

Ellen Jalkut has spent her career developing legal strategies based on detailed analysis and critical thinking. With a focus on antitrust law, she prosecutes actions involving price-fixing, unlawful monopolization and other anticompetitive practices. Ms. Jalkut draws from her knowledge in economics, along with experience representing clients in white collar defense, contract disputes, and government enforcement actions to bring a broad perspective to each case. She currently works on the team representing a class of end-user purchasers of external hard disk drives and computers who claim overcharges resulting from a price fixing conspiracy in In re HDD Suspension Assemblies Antitrust Litigation and represents a proposed class of purchasers of broadcast television spot advertising alleging that defendants engaged in a scheme to artificially inflate prices in violation of federal antitrust law. Additionally, Ms. Jalkut is on the team representing a proposed consumer end-user class in In re Granulated Sugar Antitrust Litigation.

Prior to law school, Ellen worked in economic consulting and earned her Master’s of Arts from the Economics Department at the University of Michigan, Rackham Graduate School. She relied upon her economics background in her early legal career, working closely with experts in defending clients in securities and antitrust actions. After practicing for several years, she clerked for Judge William G. Young in the District of Massachusetts.

Representative Matters

Ms. Jalkut is part of the leadership team in In re HDD Suspension Assemblies Antitrust Litigation, a complex multidistrict case alleging a global price-fixing conspiracy in the hard disk drive suspension assembly market. The team secured class certification for end-user plaintiffs and defeated a partial summary judgment motion challenging the claims under the foreign commerce exception to the antitrust laws. In this role, Ms. Jalkut helps guide strategy on behalf of the indirect purchaser class, working to hold manufacturers accountable for anticompetitive conduct and to obtain meaningful recovery for consumers affected by inflated prices.

She also serves on the leadership team representing end-user plaintiffs in In re Granulated Sugar Antitrust Litigation, which alleges that major sugar producers conspired to fix, raise, and stabilize the price of granulated sugar in violation of federal antitrust laws. Ms. Jalkut plays a key role in shaping litigation strategy for the indirect purchaser class, with a focus on uncovering industry coordination and advancing claims to secure compensation for consumers harmed by alleged overcharges.

Prior to joining Robins Kaplan, Ms. Jalkut represented a Chinese vitamin manufacturer in the early stages of the landmark In re Vitamin C Antitrust Litigation, a high-profile case involving complex questions at the intersection of international comity, antitrust enforcement, and foreign sovereign compulsion. Her work addressed novel issues regarding how U.S. courts interpret and defer to representations of foreign law by sovereign governments.

She also represented a major accounting firm during the settlement phase of one of the largest securities class actions in U.S. history. In that role, she analyzed investor claims and oversaw the settlement distribution process, ensuring accurate evaluation and efficient administration in a multi-billion-dollar matter. (Prior to joining Robins Kaplan.)

Additionally, Ms. Jalkut represented a bank in U.S. regulatory proceedings after it was designated a primary money-laundering concern under Section 311 of the USA PATRIOT Act. She engaged with the U.S. Department of the Treasury and coordinated with counsel across jurisdictions. The matter involved sensitive geopolitical considerations, including alleged illicit finance linked to North Korea, and required sophisticated legal strategy at the intersection of international banking, sanctions, and anti-money-laundering enforcement.
