Alarm.com Holdings, Inc.
A maker of cloud-based software and mobile apps that power home and business security systems, Alarm.com connects cameras, sensors, and thermostats so users can monitor and control their properties remotely. Founded in 2000 as a research unit inside the software firm MicroStrategy, the company got its name from a domain that MicroStrategy's founder had bought years earlier with no plan for it. Alarm.com went public in 2015 and its technology is sold and installed through a network of independent security service providers.

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: -10.89M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
