The filing landed 36 minutes after the bell
At 4:36 PM ET on October 9, 2026, 36 minutes after Zscaler's+7.93% — Zscaler, up 7.93 percent today fifth straight up day closed at $233.73, SEC EDGAR accepted a Form 144 from Adam Geller, Zscaler's chief product officer 123. The notice proposes selling 23,958 shares for $5,400,966.35, stock the filing says he acquired from the issuer that same day through a cash option exercise 1. It would run under a Rule 10b5-1 plan adopted March 20, 2026 1.
Five days added 18.9%; the S&P 500 added 1.2%
The streak added about $6.0 billion of market value, taking Zscaler to roughly $37.8 billion 2. Over the same five sessions the S&P 500 gained 1.2% including dividends, so the market explains almost none of the move 2. The month is up 43.0%, and the stock still sits 30.5% below its 52-week high of $336.27 from November 2025 2.
The rally repriced a slowdown
What the market bought was a reaffirmation of slower growth. At its October 6 Investor Day, Zscaler held fiscal 2027 guidance at $3.908 billion to $3.938 billion of revenue, growth of 16.6% to 17.5%, with ARR of $4.396 billion to $4.426 billion 45. Reported quarterly growth has run between 24.9% and 25.9% for four straight quarters 6. The chief revenue officer behind those quarters, Mike Rich, left effective October 1; the stock fell 8.6% on September 25 when his exit was announced 47.

The insider paper, counted
The tape is bigger than the one filing: since September 16, six Zscaler insiders have filed papers for about $11.6 million of sales counted at stated values, and no purchases appear among them 189. Geller's paper is $7.49 million of that: the proposed $5.4 million on October 9, plus September sales of $1,075,230.90, $880,173.84 and $132,200, all under the plan adopted March 20 13. His 144s have arrived every quarter, December, March, June and September 10.
The September 16 cluster runs wider: CFO Kevin Rubin at $1,148,288, chief legal officer Robert Schlossman at $448,174, CEO Jay Chaudhry at about $550,000, and Mike Rich at $791,870 81112. Rich's sale came nine days before Zscaler announced he was stepping down 713. Both his filing and Chaudhry's state the shares were sold to cover tax withholding on vesting units, as the issuer mandates, and that such a sale "does not represent a discretionary trade" 1113.
Schlossman filed another $1,078,800 on September 21 under a plan adopted July 3, 2025; Rubin another $102,390 on September 25, under a plan adopted March 24; and a director, James Beer, $33,986 81415. No Zscaler insider Form 4 has landed since September 28 9.

Eight firms raised targets after the Investor Day, to between $185 and $275 16.
