Insiders at Jersey Mike's Subs Inc. (NYSE: JMKE) have been net sellers. Over the trailing 180 days, open-market selling reached $809.8 million while open-market buying totaled $785,427, for a net figure of negative $809,006,381. The direction is not close.
The ledger breaks down this way: 8 buy filings from 5 distinct insiders on one side, and 6 sell filings from 2 distinct sellers on the other. The most recent transaction in the window carries a date of August 25th, 2026. Only Form 4 codes P and S are counted here, so the comparison is open-market money against open-market money.
The single largest seller was Blackstone Holdings II L.P., filing in the role of Other, with disposals of $705,060,432. That one entity accounts for most of the sell side on its own. The firm is an institutional holder rather than an individual officer, and its filings sit alongside a second seller to make up the rest of the total.
The largest buyer was Stacy Peterson, the Chief Operating Officer, with $345,000 of open-market purchases. That is the biggest single commitment on the buy side and it represents a meaningful share of the $785,427 bought across all 5 insiders. Operating officers buying their own stock is the kind of entry readers tend to weigh differently from an institutional block sale, though the dollar scale here is not comparable.
Jersey Mike's Subs Inc. operates in the Retail-Eating Places sector. Shares last changed hands at $17.55, putting the market capitalization at $5,574,562,816. Set against that, the $809.8 million of selling in the window is a large number relative to the company's own equity value, which is what happens when a private equity holder reduces a stake rather than when an officer trims a personal position.
There is a good deal the ledger does not say. Stock awards, restricted share vesting, shares surrendered to cover tax withholding, and option exercises are all excluded from these totals because none of them is a decision to buy or sell at a market price. A sale can also be executed under a Rule 10b5-1 plan adopted months in advance, which means the timing of a disposal is not evidence of a view on the business. For a sponsor-sized holder, selling is frequently a function of fund mechanics, lockup expiry, or a distribution schedule rather than anything specific to the quarter.
The same caution applies in the other direction. A purchase by the Chief Operating Officer tells you cash was committed at the prevailing price on the filing date, and nothing more than that. The filings record the transaction, not the reasoning.
What the record supports is a simple statement: across 180 days, 8 purchase filings and 6 sale filings produced $785,427 bought and $809.8 million sold at Jersey Mike's Subs Inc., with Blackstone Holdings II L.P. as the dominant seller and Stacy Peterson as the largest buyer.
