In October 2024 the Securities and Exchange Commission charged Matthew Groom, an IT consultant to Spero Therapeutics, with trading ahead of the May 3, 2022 announcement that Spero was suspending commercialisation of its lead drug and downsizing, avoiding losses of about $13,000. He consented, subject to court approval, to an injunction, a five-year officer and director bar, $12,936.86 in disgorgement, $2,376.22 in interest and a $12,936.86 penalty, roughly $28,000 in total.

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 this matter on October 15, 2024 as release LR-26159, filing in the District of Massachusetts.

The complaint alleges that Groom traded on non-public knowledge of the company's plans, in violation of Section 17(a) of the Securities Act and Section 10(b) of the Exchange Act. The $28,000 in the release's headline is the total of disgorgement, interest and penalty, not the disgorgement alone.
