[SCHEDULE 13G] Canadian Imperial Bank of Commerce SEC Filing

Rhea-AI Filing Summary

Bank of Montreal (BMO) and ten affiliated entities have filed a Schedule 13G on Canadian Imperial Bank of Commerce (CM) common shares. As of 30 June 2025 the group beneficially owned 46,480,692 shares (CUSIP 136069101), equating to 4.94 % of CM’s outstanding common stock. The filing is made under Rule 13d-1(b), indicating a passive investment intent.

Voting/Dispositive powers: BMO reports sole voting power over 46.16 m shares and shared voting power over 0.25 m; sole dispositive power stands at 46.23 m with the same 0.25 m shared. Key subsidiaries and their aggregate stakes include: Bank of Montreal Holding Inc. 30.42 m (3.23 %), BMO Asset Management Inc. 17.87 m (1.90 %), and BMO Nesbitt Burns Inc. Wealth Management 24.57 m (2.61 %). Several smaller units hold fractional percentages.

The certification affirms the shares were acquired in the ordinary course of business and not for the purpose of influencing CM’s control. As the holding is just under the 5 % regulatory threshold, no Schedule 13D or additional control disclosures are required.

Positive

• Significant institutional interest: A top-tier bank owning nearly 5 % of CM may be interpreted as a vote of confidence in the issuer.
• Passive filing status: Rule 13d-1(b) certification reduces risk of near-term activist intervention.

Negative

• Cross-bank ownership scrutiny: Large stake by a direct competitor could draw regulatory or antitrust attention if it rises further.
• Stake just below 5 %: Any incremental purchases could trigger stricter disclosure (13D) and potential strategic uncertainty.

Insights

Equity Research Analyst

TL;DR – BMO reveals a 4.94 % passive stake in rival bank CM; notable but sub-5 %.

This 13G filing shows BMO as a significant—yet still passive—shareholder of CM. Crossing 3 % is material for index funds; approaching 5 % is material under U.S. disclosure rules. While the stake signals confidence in CM’s valuation, the passive certification limits strategic implications. Investors should monitor any movement above 5 %, which would force a 13D and signal potential activism or strategic intent. For now, the disclosure mainly highlights institutional positioning and could marginally improve CM’s trading liquidity.

Corporate Governance Specialist

TL;DR – Cross-ownership between major Canadian banks may draw oversight but remains compliant.

BMO’s aggregate 4.94 % holding skirts the Canadian & U.S. 5 % reporting triggers for control considerations. The passive stance and dispersed subsidiary holdings reduce immediate antitrust or governance concerns. However, regulators typically scrutinize cross-ownership in concentrated banking markets; sustained or increased accumulation could invite additional disclosures or require divestiture under competition guidelines. Stakeholders should watch future filings for any transition to a 13D or movement by individual subsidiaries above 5 %.
