Checked against the primary document on October 3, 2026. The library's summary, tags and figures for this record were compared with the regulator's own document by an AI model (Claude) following written instructions, with sampled and disputed records read a second time.

In April 2024 the Securities and Exchange Commission announced that a jury in the Northern District of California found Matthew Panuwat liable for insider trading. He bought short-term call options in Incyte, a comparable company, minutes after learning that Pfizer would acquire his employer Medivation, and Incyte's stock rose about 8 percent, producing profits the SEC put above $100,000. The release does not state remedies.

A dash means the release did not state a figure we could extract, not that the figure is zero. Penalty and disgorgement are stored separately so aggregates across the library do not double-count the same dollars.

What is alleged to have happened

The Securities and Exchange Commission announced the verdict on April 8, 2024 as release LR-25970, in a case filed August 17, 2021 and tried from March 25 to April 5, 2024.

The case is the SEC's so-called shadow-trading theory: Panuwat used confidential information about his own employer's sale to trade a different company's securities. The court denied his motion to dismiss in January 2022 and his summary judgment motion in November 2023.

Same matter

The library links these 2 records because they appear to concern one matter: the same lead defendant, an overlapping technique tag and close filing dates, or a shared court docket or a release that cites the other. Records are listed by date filed.

This grouping is the library's, made by matching names, techniques, dates and citations when the site is built. It is not the regulator's or a court's determination that the records are one case, and it errs towards missing a link rather than making a false one.
