[SCHEDULE 13G/A] Battery Future Acquisition Corp. Units, each consisting of one Class A ordinary share and one-half of one redeemable warrant SEC Filing

Rhea-AI Filing Summary

Hudson Bay Capital Management LP and its control person Sander Gerber have filed Amendment No. 1 to Schedule 13G for Battery Future Acquisition Corp. (BFAC) stating that they now hold zero Class A Ordinary Shares (CUSIP G0888J108), representing 0 % of the outstanding class.

The filing, triggered as of 30 Jun 2025 and signed 07 Aug 2025, shows that all voting and dispositive powers—sole or shared—have been reduced to 0.00 shares. Hudson Bay previously reported ownership through HB Strategies LLC but now certifies ownership of “5 percent or less,” effectively terminating its status as a significant shareholder. The report is made under Rule 13d-1(b)/(c)/(d) and includes standard certifications that the securities were held in the ordinary course and not for purposes of influencing control.

Key details: (1) Reporting Persons: Hudson Bay Capital Management LP (Delaware limited partnership, investment adviser) and Sander Gerber (U.S. citizen, control person). (2) Issuer address: 8 The Green #18195, Dover, DE 19901. (3) Reporting persons’ office: 290 Harbor Dr., Stamford, CT 06902.

Implication: an institutional holder has fully exited its position, potentially reducing institutional sponsorship and float concentration, but the filing contains no commentary on BFAC’s operations or outlook.

Positive

• None.

Negative

• Hudson Bay Capital Management LP and Sander Gerber report owning 0 Class A shares, reducing their stake to 0 % of Battery Future Acquisition Corp.
• The complete exit of a previously reportable institutional holder may diminish liquidity and perceived institutional support for BFAC.

Insights

Securities Analyst

TL;DR: Hudson Bay discloses 0 % stake—signals complete exit, mildly negative for institutional support.

Hudson Bay’s amended 13G eliminates its prior reportable ownership in BFAC. For investors, the withdrawal of an event-driven fund can reduce trading liquidity and perceived institutional endorsement, although BFAC (a SPAC) still awaits a business combination. Because no economic terms of disposal are given, valuation impact is indirect: fewer locked-up shares but potential sentiment drag. The filing is strictly compliance-driven with no operational data.

Corporate Governance Expert

TL;DR: Exit removes a prior 5 %+ holder; governance influence now minimal.

Hudson Bay and Gerber disclaim any voting or dispositive power, confirming they will no longer be considered insiders under Section 13(d). This reduces the possibility of coordinated activism and simplifies BFAC’s ownership ledger. From a governance lens, the change is neutral to slightly negative: the company loses a sophisticated investor whose monitoring might have benefited minority holders.
