Schedule 13G filed by Jeremy Myung Jae Plambeck reports his beneficial ownership in BriaCell Therapeutics Corp. The filing lists 4,329.72 directly held common shares, 29,956 BCTXW warrants (reported as 2,995.6 common-share equivalents at a 10:1 exercise ratio) and 63,132.88 BCTXZ rights (reported as 6,313.29 common-share equivalents at a 10:1 conversion ratio). The filing states an aggregate ownership equal to 100.0% of the class and provides detailed vote/disposition powers for the same share counts. The filer notes delays in registry updates: conversions for BCTXZ were not reflected until 09/05/2025 and for BCTXW until 09/11/2025. The statement includes a certification that the securities are not held to change control.
Positive
Full disclosure of positions with precise counts for shares, warrants, and rights
Certification of passive intent clarifies securities were not acquired to change control
Detailed conversion ratios (10:1) and converted-equivalent counts are provided
Negative
Inconsistent aggregate totals appear in the filing text (13,338.61 v. 13,638.61) which may confuse investors
Transfer-agent/registry timing delays for BCTXZ and BCTXW conversions could temporarily misstate public records
Insights
Holder reports full class-level economic exposure via shares, warrants and rights.
The filing documents direct ownership of 4,329.72 common shares plus warrant and right positions convertible at a 10:1 ratio into an additional 2,995.6 and 6,313.29 common-share equivalents respectively, yielding the reported class percentage of 100.0%. The record includes explicit counts for voting and dispositive power matching these totals.
Registry timing differences are disclosed, with BCTXZ updates not reflected until 09/05/2025 and BCTXW until 09/11/2025, which could affect public registers and transfer agent records in the short term. Monitor formal transfer-agent confirmations and any subsequent amended filings within weeks for reconciled share counts.
Filing is structured as a passive Schedule 13G with a certification of non-control intent.
The signer checked the filing under Schedule 13G conventions and included the required certification that the securities were not acquired to influence control. The statement lists address, citizenship and signature dated 10/10/2025 consistent with filing requirements.
Because the document discloses out-of-sync registry updates, investors and registrars should watch for any amendments or clarifying statements; administrative corrections or an amended 13G could appear within the next reporting cycle if counts change.
