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

Rhea-AI Filing Summary

Norges Bank filed Amendment No. 1 to Schedule 13G disclosing a passive ownership stake in OneStream Inc. (OS).

As of 30 June 2025, the bank beneficially owned 6,343,592 common shares, representing 8.4 % of the outstanding class. Norges Bank holds sole voting and dispositive power over the entire position; no shares are held jointly. The shares are invested on behalf of the Government of Norway and were acquired in the ordinary course of business.

The filing is made under Rule 13d-1(b) as Norges Bank qualifies as a foreign institutional investor. No subsidiaries, group members, or control persons are reported, and the bank certifies that the investment is not intended to influence management or control of the issuer. The amendment mainly updates OneStream’s ownership structure, highlighting a significant passive institutional holder.

Insights

Portfolio Manager

TL;DR – 8.4 % passive stake by Norges Bank; material ownership but no control intent.

The disclosure shows Norway’s sovereign wealth arm controls over eight percent of OneStream’s float—substantial for a single passive holder. Because voting and dispositive power are sole, the stake could matter in future proxy tallies even without activist motives. However, the 13G (vs. 13D) status and explicit certification of non-control intent frame the position as purely portfolio driven. There are no transaction details, price data, or accompanying governance demands, so the market impact should be modest and largely sentiment-based, signalling ongoing institutional confidence rather than strategic change.
