They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

The Form 144 reports 1,940 shares tied to the vesting of restricted stock units scheduled on 06/15/2026. The cover line includes $245,273.24, which appears alongside the share count in the filing excerpt.

Were there prior insider sales reported in the ZS filing?

Yes. The filing shows prior sales of 1,485 shares on 03/17/2026 and 2,094 shares on 03/18/2026. These past dispositions are listed in the "Securities Sold During The Past 3 Months" section.

Are the shares being sold from compensation or open‑market holdings?

The excerpt ties the 1,940 shares to the "Vesting of Restricted Stock Units" and labels the source as Issuer for Compensation. The filing therefore associates the shares with RSU vesting rather than an existing open‑market holding.

Does the filing state how sale proceeds will be used or who receives them?

The provided excerpt does not specify the use of proceeds or who will receive sale proceeds. The cover line shows $245,273.24 but the cash‑flow recipient is not identified in the visible text.

What is the reported shares outstanding figure on the cover line?

The cover line includes the number 161,709,525, which appears adjacent to other cover details. The filing excerpt does not further label that number in context within the visible lines.
