Semtech Corp
A maker of high-performance analog and mixed-signal semiconductors and Internet of Things systems, Semtech's chips and LoRa wireless technology connect sensors, smart meters, and data centers across dozens of countries. Founded in 1960 in Newbury Park, California by two engineers, its name blends "semiconductor" and "technology." The French startup that invented LoRa's long-range wireless tech was acquired in 2012, and the name itself is a nod to how bats use chirp signals to navigate.

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 6 months: -56.4K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
