Fifteen defendants, including lawyer Nicolo Nourafchan who previously worked at Sidley Austin, Latham & Watkins, and Goodwin Procter, pleaded not guilty on Monday to charges tied to an alleged decade-long insider trading scheme built around confidential merger information. Prosecutors allege Nourafchan helped orchestrate a ring in which attorneys fed merger tips to traders before nearly 30 corporate transactions became public. Thirty people in total have been charged in the case, with authorities alleging the scheme began in 2014 and generated tens of millions in illegal profits by trading ahead of merger announcements.
Prosecutors Allege Nourafchan Orchestrated Merger Tip Network
Nicolo Nourafchan appeared in federal court in Boston to enter not guilty pleas to securities fraud and other charges. Authorities say the alleged scheme began in 2014, shortly after Nourafchan graduated from Yale Law School and joined Sidley Austin. Prosecutors claim the group generated tens of millions of dollars in illegal profits by trading ahead of merger announcements.
The case centers on the misuse of material nonpublic information. For law firms, banks, and advisers working on mergers, deal confidentiality is a core market-integrity obligation. Prosecutors are framing the alleged conduct as a long-running breach of that duty.
Alleged Scheme Involved Multiple Law Firms and Coded Communications
According to authorities, Nourafchan allegedly tipped personal injury attorney Robert Yadgarov and others about pending corporate transactions in exchange for kickbacks from trading profits. Yadgarov also pleaded not guilty.
Prosecutors allege that Nourafchan and Yadgarov recruited other attorneys into the scheme, including lawyers who worked at Wachtell, Lipton, Rosen & Katz, Weil, Gotshal & Manges, and Willkie Farr & Gallagher. One of those attorneys, Gabriel Gershowitz, secretly pleaded guilty last year and is now cooperating with prosecutors.
Eight other guilty pleas dating back to 2024 were unsealed when the case was announced in May. Those cooperation agreements could become important to the government's effort to prove how tips moved through the group, who received them, and how trading profits were distributed.
The indictment also alleges that some defendants used coded language when discussing deal tips. Prosecutors cited references to one transaction as a "flight to Israel" and another as a "rabbi." The alleged use of coded messages may become a key part of the evidence if prosecutors argue the defendants knew the information was confidential and were trying to conceal the trading activity.
Law Firm Confidentiality Controls Face Scrutiny
The presence of lawyers from major firms gives the case broader significance. Large law firms often handle confidential merger negotiations, regulatory filings, board materials, and financing details before transactions are announced. That access creates strict obligations around information barriers, employee monitoring, and trading restrictions.
For firms, the case could bring renewed attention to internal controls. Compliance systems typically restrict personal trading, monitor access to deal documents, and require employees to follow confidentiality rules.
The case also shows how insider trading exposure can extend beyond the original source of information. Traders, intermediaries, relatives, professional contacts, and business associates may all face liability if prosecutors can show they knowingly traded on confidential tips or helped transmit them.
Among the defendants is Nourafchan's brother, Lorenzo, founder of a fractional CFO and accounting firm. He also pleaded not guilty and is paying Nicolo Nourafchan's attorney fees under an arrangement that drew a warning from U.S. Magistrate Judge Judith Dein.
"You may have different interests as this goes on," Dein said.
Defense Attorneys Assert Innocence as Case Moves to Discovery
The not guilty pleas move the case toward discovery, pretrial motions, and potential trial preparation. Prosecutors are likely to rely on trading records, communications, cooperation testimony, and law firm access logs to connect alleged merger tips with specific trades.
Martin Weinberg, a lawyer for Nicolo Nourafchan, said his client "asserted his innocence to each allegation at his arraignment today and we intend a vigorous and compelling defense."
Joseph Suskind, a Florida resident in the insurance adjusting business, is also among the defendants. He is accused of trading in 2022 on tips related to SailPoint's agreement to be acquired by Thoma Bravo and iRobot's later-abandoned deal to be acquired by Amazon. His lawyer, Michael Kendall, rejected the allegations.
"Evidence is more important than press releases," Kendall said after Suskind's arraignment. "We look forward to the trial."
