[Form 4] Marathon Bancorp, Inc. Insider Trading Activity

Rhea-AI Filing Summary

VivoPower International PLC (VVPR) — Schedule 13G/A Amendment No. 3

The filing discloses that individual investor Thomas John Corley beneficially owns 635,000 ordinary shares of VivoPower International PLC, representing 6.3 % of the company’s 10,112,212 outstanding shares (per Form F-1 dated 7 May 2025). The event triggering the filing occurred on 30 June 2025.

Ownership details show that Corley has sole voting and dispositive power over the entire holding and no shared power. The Schedule 13G certification states the securities were not acquired to influence control, indicating a passive investment under Regulation 13d-1(c).

Because the holding exceeds the 5 % threshold, the disclosure increases transparency of VVPR’s share register and may be material for investors tracking float concentration or potential future governance dynamics. No additional financial metrics, transaction terms, or intentions to change control are provided.

Positive

• 635,000 shares (6.3 %) disclosure adds clarity to VVPR’s ownership structure.
• Sole voting and dispositive power simplifies governance analysis by identifying a single decision-maker behind the stake.

Negative

• No stated strategic intent; investors gain little insight into how the stake might influence corporate actions.
• Increased ownership concentration could marginally reduce free float liquidity for VVPR shares.

Insights

Securities Analyst

TL;DR – Passive investor now reported with 6.3 % of VVPR; limited immediate impact.

The amendment shows Thomas Corley crossing (or remaining above) the 5 % reporting line with 635 k shares. While a 6.3 % stake is sizeable for a micro-cap such as VivoPower, the 13G (rather than 13D) suggests no activist agenda. The disclosure therefore mainly tightens float information rather than signalling operational change. Liquidity dynamics could marginally tighten but, in my view, market impact should be modest unless the holder later switches to an active stance.

Corporate Governance Expert

TL;DR – New >5 % holder adds transparency; governance influence limited for now.

A single individual controlling 6.3 % can become influential in tightly held companies, yet the filer explicitly certifies a passive position. Board composition, proxy matters, and takeover defences remain unchanged. Investors should nonetheless monitor future amendments; a conversion to Schedule 13D would signal a shift toward activism. At present the filing is informational, not transformative.
