Rubrik Class A sale notice by Lightspeed funds

Rubrik, Inc. has a notice covering potential sales of its Class A securities.

Rhea-AI Filing Summary

Rubrik, Inc. has a notice covering potential sales of its Class A securities. The securities information section lists Merrill Lynch, Pierce, Fenner & Smith Incorporated together with numerical figures 7,592, 636,209.6, 160,956,763, the date 07/13/2026, and the NYSE.

A section on securities sold during the past 3 months lists Class A entries for Lightspeed General Partner IX, LP, Lightspeed General Partner Select II, LP, Lightspeed Management Company, LLC, and Eggers Investments LP – Fund 2, with amounts such as 7,592, 155, 3,979, and 50,000 associated with late June 2026 transactions.

Filing Explained

As of July 13, the filing proposes resale of 7,592 Class A shares for $636209.6; it does not report a new issuance or completed sale.

The July 13 Form 144 reports a proposed resale—not a completed sale—of Rubrik Class A shares, covering 7,592 shares for $636209.6, and if carried out, the disclosed consequence is holder resale activity rather than a new Rubrik issuance.

The filing says these shares were acquired from the issuer on January 27, 2014 in a private placement for cash. The supplied definition describes a private placement as a sale of securities to selected investors outside a public offering, with resale potentially requiring a later registration statement.

It also records past-three-month sales by four named holders: Lightspeed General Partner IX, LP sold 7,592 shares for $538,524 on June 26, 2026; Lightspeed General Partner Select II, LP sold 155 shares for $10,995 that day; Lightspeed Management Company, LLC sold 3,979 shares for $282,244 on that day; and Eggers Investments LP - Fund 2 sold 50,000 shares for $3,891,955 on June 30, 2026.

The key unresolved step is whether the proposed 7,592-share resale occurs; the July 13 filing itself supplies no completed-sale result.

"An acquisition entry lists "Private Placement" as the manner of acquisition"

A private placement is a sale of securities directly to a selected group of investors, typically institutions or accredited investors, instead of through a public offering. It lets a company raise money faster and with fewer regulatory steps; for existing shareholders it matters because the newly issued shares, often sold at a discount, increase the share count and can dilute their ownership.
