Eric S. Marmurek: trading record in brief
Eric S. Marmurek, listed as senior executive, appears in our data through filings on Ribbon Communications Inc. shares, published by SEC (Form 4). Between 16 September 2021 and 15 October 2026, the trades on record add up to 22 filings.
Not one of the filings records a straightforward purchase or sale on the market. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.
The newest entry dates from 19 October 2026: an option exercise, in Ribbon Communications Inc. The median gap between a trade and its publication by SEC (Form 4) is 3 days. US insiders must file a Form 4 within two business days of a trade. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
