Geospace Technologies Corporation
A Houston-based maker of rugged sensing gear that listens to the ground, Geospace Technologies builds the geophones, hydrophones, and cable-free seismic nodes used by oil and gas crews to map what lies beneath the Earth's surface. Born in 1980 as OYO Geospace, a subsidiary of Japan's OYO Corporation, it struck out on its own and renamed itself Geospace Technologies in 2012. Beyond oil, its gear now tracks leaky water pipes, guards borders with seismic-acoustic sensors, and even spots intruders by their heartbeat.

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.
