Diane E. Wilfong

Diane E. Wilfong, listed as finance chief, appears in our data through filings on Gilead Sciences, Inc. shares, published by SEC (Form 4). We count 15 filings; the first trade dates from 10 August 2021 and the latest from 10 September 2025.

Not one of the filings records a straightforward purchase or sale on the market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

The latest filing, published on 11 September 2025, reports an option exercise in Gilead Sciences, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
