[SCHEDULE 13G] Oklo Inc. SEC Filing

Rhea-AI Filing Summary

The Vanguard Group filed a Schedule 13G reporting passive ownership of 963,170 Nabors Industries (NBR) common shares as of 30 Jun 2025. The position equals 6.13 % of NBR’s outstanding stock, placing Vanguard above the 5 % reporting threshold.

• Sole voting power: 0 shares – Vanguard does not independently vote any of the shares.
• Shared voting power: 7,940 shares.
• Sole dispositive power: 942,548 shares.
• Shared dispositive power: 20,622 shares.

The filing is made under Rule 13d-1(b) as Vanguard is an investment adviser (IA). The certification states the shares were acquired in the ordinary course of business and not to influence control of the issuer.

For investors, the key takeaway is that a large passive manager now discloses a >6 % economic stake. While this does not signal strategic intent, it highlights continued institutional interest and may enhance NBR’s trading liquidity and index eligibility.

Positive

• Vanguard discloses a 6.13 % stake, adding a well-regarded institutional holder to NBR’s shareholder base, which can improve liquidity and benchmark inclusion prospects.

Negative

• None.

Insights

Portfolio Manager

TL;DR – Vanguard’s 6.13 % passive stake signals institutional support; no control implications.

Vanguard’s disclosure confirms that a top-tier index fund manager holds a meaningful slice of Nabors Industries. As a passive IA, Vanguard is unlikely to agitate for governance changes, but its presence can tighten the float and increase index-related demand. The absence of sole voting power underscores its fiduciary structure: voting decisions often follow proxy-policy guidelines rather than activism. From a valuation standpoint, the filing neither changes cash flows nor capital structure, so I view the market impact as neutral—possibly modestly supportive due to higher institutional ownership.
