A maker of lab reagents—the fluids, buffers, agar plates, and cell-culture media that scientists mix with and grow samples in—for drug developers and diagnostic companies. Founded in 1996 by Ted Davis, a former Genentech scientist who started mixing custom plates in his Half Moon Bay garage, the firm (headquartered in Hollister, California) now ships both off-the-shelf and made-to-order supplies to labs worldwide. Its name is a mashup of "technology" and "nova," hinting at newness.
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 all recorded history: +21.41M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
