Shareholder Meeting

On November 28, 2025, the Company held a Special Meeting of Shareholders at which a quorum was present, at which the shareholders of the Company approved the following proposals:

As a result of the approval of Proposal 3, the Company intends to (a) issue an aggregate of 732,384 Class B Special Shares issuable pursuant to the terms of the Debt Settlement Agreements, which convert in accordance with their terms into a like number of Common Shares, and (b) issue up to 27,300,000 Common Shares, from time to time in accordance with its terms, which is the maximum number of shares issuable upon the conversion of US$4,909,995.28 of principal, plus interest, under the PGC Note and the Dunstan Note.

In addition, as a result of the approval of Proposal 1, the Company may strategically effect one or more additional reverse stock splits from time to time without further shareholder approval at different ratios. The Company’s decision whether or not (and when) to effect additional reverse stock splits (and at what ratio to effect such reverse stock splits) will be based on a number of factors, including market conditions, existing and anticipated trading prices for the common shares and the requirements of the Nasdaq Capital Market. The Company has historically effected reverse stock splits when there is downward pressure on the trading price of its common shares.

Marijuana’s medical framework in the United States is evolving, but recreational use remains illegal under U.S. federal law, and the enforcement of U.S. cannabis laws will change as a medical regulatory framework is developed.

There are significant legal restrictions and regulations that govern the cannabis industry in the United States. Marijuana remains a Schedule I drug under the Controlled Substances Act, making it illegal under federal law in the United States to, among other things, cultivate, distribute or possess cannabis in the United States. As of 2024, 47 states, the District of Columbia, and the U.S. Territories of Guam, Puerto Rico, and the U.S. Virgin Island allow the of cannabis for medical purposes. 24 states and the District of Columbia have legalized cannabis for recreational purposes. In those states in which the use of marijuana has been legalized, its use remains a violation of federal law pursuant to the Controlled Substances Act. The Controlled Substances Act presently classifies marijuana as a Schedule I controlled substance, and as such, medical and adult use cannabis use is illegal under U.S. federal law; however, reclassification to Schedule III is in process.

On December 18, 2025, President Trump signed an executive order directing the Attorney General to expedite the reclassification of cannabis from a Schedule 1 to a Schedule III substance under the Controlled Substance Act. While the order does not federally legalize marijuana or its recreational use, it marks a significant policy shift by formally recognizing the drug’s potential medical value for the first time in over 50 years. Schedule III indicates evidence supporting accepted medical use and the moderate to low potential for physical and psychological dependence. The primary implications of rescheduling are: (a) the elimination of IRS Section 280E which enables state-legal cannabis business to deduct standard operating expenses from their federal taxes, (b) reduced administrative and regulatory barriers for clinical trials, (c) a pathway for the Food & Drug Administration (FDA) to develop federal standards for product quality, labeling accuracy, and consumer protection, (e) reduced legal risks for financial institutions, (f) the listing of U.S. medicinal cannabis companies on U.S. stock exchanges, and (g) federal de-prioritization on non-violent marijuana offenses. Rescheduling, nonetheless, does not permit interstate commerce of cannabis within the United States, nor does it override state laws criminalizing marijuana use or provide full banking protections for financial institutions providing traditional services to the U.S. cannabis market. As part of the executive order, a pilot program was established for Medicare beneficiaries to receive up to $500 annually for doctor-recommended CBD products starting in 2026.

However, until this proposed rescheduling rule is finalized by the Attorney General and until the FDA promulgates the regulatory framework with respect to medicinal marijuana , there is a risk that federal authorities may enforce current federal law. Financial transactions involving proceeds generated by, or intended to promote, cannabis-related business activities in the United States may form the basis for prosecution under applicable U.S. federal money laundering legislation. While the approach to enforcement of such laws by the federal government in the United States has trended toward non-enforcement against individuals and businesses that comply with medical or adult-use cannabis regulatory programs in states where such programs are legal, strict compliance with state laws with respect to cannabis will neither absolve us of liability under U.S. federal law, nor will it provide a defense to any federal proceeding which may be brought against us should we expand our operations into the U.S. However, since U.S. federal law criminalizing the use of marijuana pre-empts state laws that legalize its use, enforcement of federal law regarding marijuana may be a significant risk and could greatly harm our business, prospects, revenue, results of operation and financial condition if we were to expand our operations into the United States. We currently have no operations in the United States and no current plans to expand our operations into the United States in the foreseeable future.

Our activities are, and will continue to be, subject to evolving regulation by governmental authorities. The legality of the production, cultivation, extraction, distribution, retail sales, transportation and use of cannabis differs among states in the United States. Due to the current regulatory environment in the United States, new risks may emerge; management may not be able to predict all such risks. Due to the conflicting views between state legislatures and the federal government regarding cannabis, cannabis businesses are subject to inconsistent laws and regulations. There can be no assurance that the federal government will not enforce federal laws relating to marijuana and seek to prosecute cases involving marijuana businesses that are otherwise compliant with state laws in the future. To date, federal enforcement agencies have taken little or no action against state-compliant cannabis businesses in the United States. However, the DOJ may change its enforcement policies at any time, with or without advance notice. The uncertainty of U.S. federal enforcement practices going forward and the inconsistency between U.S. federal and state laws and regulations may present risks for us if we expand our operations into the United States in the future; however the reclassification to Schedule III and the possibility of a future FDA medicinal regulatory framework for cannabis may reduce some of this uncertainty.
