Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 63% of sales by value ran under 10b5-1 trading plans disclosed in the filings, 0.1% were to cover taxes and 37% had no disclosed plan. A trading plan schedules sales in advance.
Yes. 2 officers or directors reported 4 purchases in the past 12 months (Form 4 code P; rows the filings describe as reinvested dividends, plan purchases, private deals or moves into the person's own trust are not counted).

Holdings and share of stake for Alphatec Holdings, Inc. are being verified, so no balances, unit counts or percentages are shown. Sales, proceeds, plan and tax status, titles and dates come straight from individual filings.
Officer and director open-market sales: $28.2M across 1,724,321 shares. Plan status and stated purpose are separate questions, and a sale can have both.
The lighter segment is sales with no plan disclosed in the filing ($10.5M), including tax-related sales outside a plan.
Sales with no 10b5-1 plan and no tax reference in the filing. $3.9M of it is Scott Lish. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Jeffrey Rydin, Nov 3, 2025
$6.1M of sales (21.5%) cite tax obligations in their footnotes, $6.1M of them also under a plan. Separately, 397,103 shares ($5.4M) were withheld by the company for taxes, which isn't a market sale. Example: Tyson Marshall, Aug 5, 2026
2 officers and directors bought shares in this period, in 4 trades(Form 4 code P, leaving out rows the filings describe as reinvested dividends, plan purchases, private deals or moves into the person's own trust). Across all their filings on record there are 30 purchase trades.

More than usual: about 1.6x the 5-year average. 9 insiders sold; the average is 7 a year.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.
Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Alphatec Holdings, Inc. are held back until that check is finished. Sales, proceeds, plan and tax status, titles and dates come straight from individual filings and are complete.
External context: we only cite outside events when a documented connection exists. None is shown for this period.
All 929 Forms 3, 4 and 5 on record for Alphatec Holdings, Inc. (SEC CIK 1350653), filed from Jun 2, 2006 to Oct 5, 2026; 59 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 13, 2026. Prices are the ones reported in each filing, often weighted averages.
Probable 1-for-12 stock split on or before Nov 15, 2016 (first filing that shows post-split balances). Splits aren't reported as transactions; 7 holding lines changed by exactly this ratio, so earlier share counts are restated.
Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.
Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
