ProMIS Neurosciences Gains New 10% Holder via Shaf QIC Filing

Rhea-AI Filing Summary

On 31 Jul 2025 Shaf QIC LLC and its manager, Jonathan Shafmaster, filed Amendment No. 1 to Schedule 13G disclosing a 10.01 % beneficial stake in ProMIS Neurosciences Inc. (PMN).

Key details:

• Total securities reported: 10,534,639 Common Shares.
• Composition: 5,184,760 outstanding shares plus 5,349,879 shares underlying warrants.
• The warrants are subject to a 9.99 % ownership blocker, so fewer shares can currently be exercised; full ownership would reach 10.01 % of the 51,806,497 shares outstanding at 31 Jul 2025.
• All voting and dispositive power is solely held by the reporting persons; no shared power is indicated.
• The filing is made under Rule 13d-1(c) and includes a certification of passive intent—no present plans to influence control of the issuer.

The filing introduces a new >5 % shareholder and highlights potential dilution once the blocker constraint is lifted.

Positive

• A new 10 % beneficial owner signals confidence in ProMIS Neurosciences’ prospects
• Filing under passive Rule 13d-1(c) reduces immediate activism risk

Negative

• 5.35 M warrants represent a potential 10 % dilution overhang if the ownership blocker is waived or capacity grows

Insights

Financial Analyst

TL;DR: 10% stake disclosed; passive intent; warrants create future dilution risk.

This 13G/A shows Shaf QIC’s combined equity and warrant position would equal 10.01 % of PMN, signalling a sizable vote of confidence but also adding a potential 5.3 M-share overhang. Because the warrants cannot be exercised above 9.99 %, immediate voting influence stays capped. The passive Rule 13d-1(c) filing suggests no activist agenda. For valuation models, investors should consider possible dilution and the leverage a single holder gains as PMN seeks capital in the neurology pipeline.

Portfolio Manager

TL;DR: Neutral—large passive holder emerges; monitor warrant blocker expiry.

Entry of a 10 % owner seldom moves a micro-cap by itself, but it tightens the float and could improve secondary-market support. Yet, 5.35 M unexercised warrants equate to roughly 10 % additional supply that may cap long-term upside unless offset by value-creating catalysts. Because the filer certifies no intent to seek control, governance risk is minimal. Overall impact: watch dilution dynamics, not immediate strategy shifts.

Comment for Type of Reporting Person: Consists of (i) 5,184,760 Common Shares, no par value per share (the "Common Shares") and (ii) 5,349,879 Common Shares issuable upon exercise of warrants, none of which are currently exercisable. The reported warrants contain provisions preventing their exercise to the extent that such exercise would result in the holder (together with its affiliates) obtaining greater than 9.99% of the Issuer's Common Shares (the "Beneficial Ownership Blocker"). However, the amounts reported in rows (5), (7) and (9) herein represent the number of Common Shares issuable upon exercise of the warrants in full, and do not give effect to the Beneficial Ownership Blocker. Therefore, the actual number of Common Shares beneficially owned by the Reporting Persons, after giving effect to the Beneficial Ownership Blocker, is less than the number of shares reported in rows (5), (7) and (9). The percent of class was calculated based upon 51,806,497 Common Shares of the Issuer outstanding as of July 31, 2025, as reported by the Issuer on July 31, 2025.
