[SCHEDULE 13G/A] Rubrik, Inc. SEC Filing
Greylock XIV entities reported beneficial ownership of Rubrik, Inc. (Class B common stock) with convertible rights into Class A shares. Greylock XIV Limited Partnership directly holds 4,476,448 Class B shares, which the filing treats as equivalent to 3.50% of Rubrik's outstanding Class A common stock for percentage calculations. Two related entities, Greylock XIV-A Limited Partnership and Greylock XIV Principals LLC, each directly hold 248,691 Class B shares (each ~0.20% on a Class A equivalent basis). Combined holdings attributable to Greylock XIV GP LLC total 4,973,830 Class B shares, reported as approximately 3.87% of outstanding Class A stock when converted for percentage purposes. Each Class B share carries 20 votes versus one vote for Class A, and the filing states the combined voting power represented by these Class B holdings is 6.54% of aggregate combined voting power based on the issuer's reported share counts as of May 31, 2025.

Insights
TL;DR: Greylock XIV maintains a meaningful minority economic stake; its outsized voting rights modestly increase governance influence.
The filing shows direct ownership of 4.48 million Class B shares by Greylock XIV Limited Partnership and additional holdings across affiliated entities, with 4.97 million Class B shares attributable to Greylock XIV GP LLC. For economic ownership measured on a Class A-equivalent basis the stake is reported at roughly 3.5%–3.9%, below a 5% Schedule 13D threshold. However, Class B shares carry a 20:1 voting multiplier, producing a larger share of combined voting power (reported as 5.88% for the largest entity and 6.54% aggregated). This structure means Greylock’s voting influence is materially larger than its economic percentage and should be considered when assessing control dynamics, board voting outcomes, and shareholder coalition scenarios.
TL;DR: Ownership disclosure is thorough; dual-class structure amplifies voting weight though economic ownership remains modest.
The Schedule 13G/A clearly discloses conversion rights, transfer triggers, and the 20-for-1 voting differential between Class B and Class A shares. Greylock’s reported Class B holdings convert into Class A for percentage calculations under Rule 13d-3, which understates the practical voting influence from a governance perspective. The filing is compliant and provides the necessary detail for investors to understand both economic and voting stakes. No changes to management or control are indicated in the filing itself.
