First Solar, Inc.
A maker of thin-film solar panels, First Solar is the largest solar manufacturer in the Western Hemisphere, headquartered in Phoenix, Arizona. Its panels use cadmium telluride coated onto glass in a process closer to making flat-screen TVs than to cutting silicon wafers. The company began in 1990 as Solar Cells, Inc., founded by glass-industry inventor Harold McMaster, and was renamed First Solar in 1999 after a new ownership group took over.

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: -122.8K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
