[SCHEDULE 13G/A] dMY Squared Technology Group, Inc. SEC Filing

Rhea-AI Filing Summary

Bank of Montreal and affiliates have filed Amendment No. 1 to Schedule 13G for dMY Squared Technology Group, Inc. (DMYY). As of the event date 07 Jul 2025, the Bank of Montreal, Bank of Montreal Holding Inc. and BMO Nesbitt Burns Inc. jointly report beneficial ownership of 30,307 Class A common shares (CUSIP 233276104), representing 1.3 % of the outstanding class.

All voting and dispositive authority is shared; each entity reports 0 shares with sole power and 30,307 shares with shared power to vote and dispose. The position is held in the ordinary course of business while acting as prime broker for clients; the filers state the shares were not acquired to influence control of the issuer. Each reporting person classifies as a bank/holding company or broker-dealer under Rule 13d-1(b).

The filing confirms ownership below the 5 % threshold; no plans, arrangements or group agreements affecting control are disclosed. Certification language affirms passive investment intent.

Insights

Sell-Side Equity Analyst

TL;DR: Minor 1.3 % stake; passive, routine disclosure—no material impact on DMYY valuation.

The BMO group’s combined 30,307-share position is well under the 5 % level, signalling a standard prime-broker holding rather than a directional investment call. With no sole voting power and explicit passive-ownership certification, the filing does not suggest activism or strategic interest. From an equity-valuation standpoint, this disclosure is informational only and should not alter the investment thesis or liquidity profile of DMYY.

Corporate Governance Specialist

TL;DR: Governance risk unchanged; filing evidences compliance with Section 13 but lacks control implications.

The Schedule 13G/A demonstrates regulatory compliance by BMO entities and clarifies that their stake is client-related. Shared voting authority across three Canadian entities indicates internal aggregation of brokerage positions rather than coordinated action. No group intent or control ambitions are asserted, limiting governance significance. Consequently, board influence, takeover risk, and shareholder-proposal dynamics remain unaffected.
