[SCHEDULE 13G/A] Rubrik, Inc. SEC Filing

Rhea-AI Filing Summary

Lightspeed-affiliated investors and three named individuals reported beneficial ownership stakes in Rubrik, Inc. The filing (Schedule 13G/A) discloses holdings as of June 30, 2025: several Lightspeed entities collectively report Class B holdings (largest single Lightspeed pool: 5,549,816 shares) and affiliated special-purpose vehicles report additional Class B shares. Individual reporting persons Barry Eggers, Ravi Mhatre and Peter Nieh each hold substantial Class A positions: 415,424, 552,162 and 515,423 shares respectively, with each individual’s aggregate beneficial ownership reported around 13.2–13.35 million shares representing 9.1% of the class. The percentage calculations reflect 123,563,326 Class A shares outstanding (reported May 31, 2025) plus 9,641,000 shares issuable on conversion of Class B shares held by the Reporting Persons. The Reporting Persons expressly disclaim status as a "group." The filing is signed and dated August 14, 2025.

Insights

Financial Analyst

TL;DR: Lightspeed entities and three insiders disclose meaningful, disclosed stakes (~4.2% Lightspeed umbrella; ~9.1% each for named individuals), clarifying ownership structure.

The Schedule 13G/A aggregates detailed beneficial ownership across multiple Lightspeed funds and related entities and shows material individual holdings by Eggers, Mhatre and Nieh. The filing uses the issuer's May 31, 2025 share count plus 9,641,000 shares from conversion to compute percentages, yielding reported stakes of up to 9.1% for each named individual and up to 4.2% for certain Lightspeed management entities. This provides investors clear, SEC-compliant transparency on who holds convertible Class B positions and their potential dilutive effect when converted to Class A common stock.

Corporate Governance Expert

TL;DR: Filing clarifies voting and dispositive arrangements: holdings are largely reported as shared voting/dispositive power and Reporting Persons disclaim being a group.

The report itemizes sole versus shared voting and dispositive power for each filing entity: most Lightspeed vehicles report 0 sole voting/dispositive power and significant shared power (examples: 5,549,816 shared voting for Lightspeed IX; LS SPV shows 5,862,326 shared voting). The explicit disclaimer that the Reporting Persons are not a "group" and the layered GP/ultimate GP structure (Cayman entities as general partners) are significant corporate-governance disclosures that clarify control lines and trustee/manager relationships for shareholders and the board.
