Strata Critical Medical, Inc.
A healthcare services company that rushes donor organs to transplant centers via air and ground, under the Trinity brand, and provides surgical recovery, preservation, and cardiac perfusion staffing under Keystone. Born in 2014 as Blade Air Mobility, the helicopter passenger app, it pivoted during the pandemic to organ transport and rebranded as Strata in 2025. Fun fact: its old name "Blade" honored helicopter rotor blades.

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: -3.46M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
