Alphatec Holdings, Inc.
A designer and seller of spinal implants, fixation systems, biologics, and surgical instruments for treating spine disorders, Alphatec centers its lineup on the Prone TransPsoas (PTP) lateral approach, SafeOp nerve monitoring, and an imaging-and-robotics platform built on EOS whole-body scans and Valence surgical navigation. The company began in 1990 as a contract manufacturer for other medical-device firms, renamed itself Alphatec Spine in 2005 to mark its shift to its own spine products, and later folded EOS imaging into its platform in 2021.

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 year: -5.43M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
