Affiliated Broker-Dealers Disclose 18.34M Shares in Core Scientific CORZZ

Rhea-AI Filing Summary

Reporting persons G1 Execution Services, LLC; SIG Brokerage, LP; Susquehanna Investment Group; and Susquehanna Securities, LLC disclose an aggregate beneficial ownership of 18,336,176 shares of Core Scientific, Inc. common stock, representing 6.2% of the class based on the company’s reported 297,821,835 shares outstanding. The reported position includes direct holdings and securities exercisable or convertible into shares, including options and warrants.

The filing states these affiliated broker-dealers may be deemed a group and reports both sole and shared voting and dispositive power across the reporting persons. The reporting persons certify the holdings are held in the ordinary course of business and not for the purpose of changing control. Investors should note that part of the position derives from options, warrants or convertible instruments and therefore may reflect potential dilution rather than current free-floating shares.

Positive

• The group discloses an aggregate beneficial ownership of 18,336,176 shares, providing clear transparency about a >5% position in the company.
• The filing states holdings are held in the ordinary course of business and not for the purpose of changing or influencing control, clarifying intent.

Negative

• A portion of the reported position consists of options, warrants and shares issuable upon conversion, which may not represent current free-floating shares and can be dilutive if exercised.
• Reporting persons are affiliated and may be deemed a group, with shared voting/dispositive power across entities, which could concentrate influence despite disclaimers of beneficial ownership.

Insights

Financial Analyst

TL;DR: A group of affiliated broker-dealers reports a material 6.2% position (18.34M shares) in CORZZ, including options/warrants.

The filing shows an aggregate position of 18,336,176 shares representing 6.2% of the outstanding common stock as reported by the issuer. Material detail: portions of the disclosed stake arise from options, warrants and convertible securities, with SIG Brokerage and Susquehanna entities listing significant exercisable instruments. That distinction matters because exercise/conversion timing affects actual share count and potential dilution. The report also discloses both sole and shared voting/dispositive power across the affiliated entities, which can influence how votes and dispositions are coordinated operationally. Overall impact is material as a >5% holder disclosure, but neutral in directional signal since the filing affirms holdings are in the ordinary course of business.

Corporate Governance Expert

TL;DR: Affiliated broker-dealers may be deemed a group with shared voting/dispositive power; they expressly disclaim ownership of each other’s direct holdings.

The document explicitly notes the reporting persons are affiliated independent broker-dealers that "may be deemed a group." It reports shared voting and dispositive power over the full aggregate position while also stating each entity disclaims beneficial ownership of shares owned directly by another reporting person. This dual statement is important: it preserves each entity’s legal disclaimers while acknowledging operational affiliation. For governance and proxy contexts, the grouping language and shared powers are material facts for understanding potential coordination in voting or disposition, though the filing asserts the holdings are not intended to change control. Impact on shareholder governance is material but neutral absent evidence of coordinated strategic intent.
