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

Rhea-AI Filing Summary

FMR LLC (Fidelity) and Abigail P. Johnson have filed Amendment No. 2 to Schedule 13G on MACOM Technology Solutions Holdings Inc. (NASDAQ: MTSI) for an event dated 30 Jun 2025.

• Beneficial ownership: 5,595,985.16 common shares
• Percent of class: 7.5 %
• Sole voting power: 5,573,712.64 shares
• Sole dispositive power: 5,595,985.16 shares

The shares are held in the ordinary course of business; the Schedule 13G filing confirms the position is passive rather than activist. FMR LLC is classified as a “parent holding company or control person” under Rule 13d-1(b)(1)(ii)(G). No other entity’s interest exceeds 5 % of the outstanding common stock.

Signatures were executed by Richard Bourgelas under power of attorney on 5 Aug 2025. The disclosure signals continued institutional support from Fidelity but does not indicate any intention to influence management or corporate strategy.

Positive

• Institutional support: Fidelity-managed FMR LLC now controls 7.5 % of MTSI, signaling confidence from a large, long-term investor.

Negative

• Limited strategic influence: Filing under Schedule 13G denotes a passive stance, implying no activist catalyst or immediate governance change.

Insights

Portfolio Manager

TL;DR – Fidelity now owns 7.5 % of MTSI in a passive capacity; supportive yet non-activist.

The 13G/A shows FMR’s stake has grown to 5.6 million shares, giving the firm a meaningful but non-controlling position. Passive classification limits the probability of governance interventions, yet Fidelity’s long-term track record often attracts additional institutional interest and can enhance liquidity. From a portfolio standpoint the filing is neutral-to-modestly positive; it affirms ongoing confidence without introducing strategic uncertainty.

Corporate Governance Specialist

TL;DR – Large passive holder, no control intent, limited governance impact.

Because FMR opted for a 13G (not 13D) it attests that the holding is strictly investment-driven. Sole voting and dispositive authority remain with FMR, but below the 10 % threshold the firm holds no enhanced reporting duties. Board dynamics are unlikely to change. Overall governance impact is neutral; however, the presence of a reputable institutional owner can deter volatility and facilitate future capital raises.
