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

Rhea-AI Filing Summary

This Schedule 13G/A discloses that a group of affiliated entities led by Susquehanna Advisors Group, Inc. and Capital Ventures International beneficially own 8,466,499 shares of First Solar, representing 7.9% of the outstanding common stock based on 107,247,360 shares reported outstanding as of June 30, 2025.

The filing breaks down voting and dispositive authority: Susquehanna Securities, LLC reports sole voting and dispositive power over 7,521,635 shares, Capital Ventures International reports sole voting and dispositive power over 600,000 shares, and several affiliated broker-dealers report smaller sole holdings while the reporting persons disclose shared voting and dispositive power across the group. The statement affirms the shares were acquired and are held in the ordinary course of business and not to change control, and attaches a Limited Power of Attorney and a Joint Filing Agreement.

Insights

Financial Analyst

TL;DR: Susquehanna-led group holds a material passive stake of 8.47M shares (7.9%) in FSLR, disclosed on Schedule 13G/A.

The filing reports an aggregate beneficial ownership of 8,466,499 shares, equal to 7.9% of First Solar based on 107,247,360 shares outstanding as of June 30, 2025. The composition includes substantial option positions disclosed for certain filers (notably 6,748,700 options included in Susquehanna Securities, LLC’s reported amount). Because this is a Schedule 13G/A, the reporting persons characterize the position as passive and acquired in the ordinary course of business. For market participants, a disclosed position near 8% is material to voting dispersion and potential block trading liquidity, but the filing presents no change-of-control intent.

Corporate Governance Expert

TL;DR: Group filing clarifies voting/dispositive arrangements and disclaims intent to influence control; Susquehanna Advisors may manage CVI voting rights.

The report details both sole and shared voting and dispositive powers across the reporting persons: Susquehanna Advisors Group, Inc. is identified as investment manager to Capital Ventures International and may exercise voting/dispositive power over CVI-held shares. The filing includes a Limited Power of Attorney and a Joint Filing Agreement, and contains the certification that holdings were not acquired to influence control. From a governance perspective, the disclosure clarifies relationships and authority among affiliated entities but does not signal an active governance campaign.
