In January 2025 the Securities and Exchange Commission announced final consent judgments entered on December 23, 2024 against Joseph Dupont, Shawn Cronin, Stanley Kaplan, Paul Feldman and Jarett Mendoza in the Portola Pharmaceuticals tipping chain, in which Dupont, an Alexion vice president, tipped Cronin ahead of Alexion's acquisition. Each was enjoined and barred from serving as an officer or director of a public company; Dupont was ordered to pay a $36,000 penalty. All five had pleaded guilty in parallel criminal cases.

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 these judgments on January 3, 2025 as release LR-26209, in a Southern District of New York case filed June 29, 2023.

The release reports criminal sentences and forfeitures: Cronin three months and $71,996.06 forfeited, Kaplan five months and $472,053.61, Feldman three months, $1,730,827.54 and a $25,000 fine, Mendoza $38,648.58 forfeited, and a $75,000 fine for Dupont. Only the $36,000 civil penalty against Dupont is recorded as the civil money amount.

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.
