On Semiconductor Corporation
A maker of smart power and image-sensing chips used in cars, factories, and AI data centers, onsemi produces the EliteSiC line of silicon carbide chips that help electric vehicles go farther and charge faster. Born in 1999 as a spinoff of Motorola's chip business, it later swallowed the pioneering Fairchild Semiconductor. Its lowercase "onsemi" name was chosen in 2021 partly so it would rank better in web searches.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: -425.1K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
