Notes to Financial Statements
Warrants [Text Block]	*Note 13.* Warrant liability** As of August 31, 2025 and May 31, 2025, there were 6,209,000 warrants outstanding, with an original exercise price of $5.95 per warrant, expiring September 17, 2025. Each warrant is exercisable for one share of Common Stock of the Company. The warrants contain anti-dilution price protection features, which adjust the exercise price of the warrants if the Company subsequently issues Common Stock at a price lower than the exercise price of the warrants. In the event additional warrants or convertible debt are issued with a lower and/or variable exercise price, the exercise price of the warrants will be adjusted accordingly. During the three months ended August 31, 2025, the Company issued shares of its Common Stock which triggered the anti-dilution price protection feature and, accordingly, lowered the exercise price of each warrant to $0.38. These warrants are classified as liabilities as they are to be settled in registered shares, and the registration statement is required to be active, unless such shares may be subject to an applicable exemption from registration requirements. The holders, at their sole discretion, may elect to affect a cashless exercise, and be issued exempt securities in accordance with Section 3(a)(9) of the Securities Act of 1933, as amended. In the event the Company does not maintain an effective registration statement, the Company may be required to pay a daily cash penalty equal to 1% of the number of shares of Common Stock due to be issued multiplied by any trading price of the Common Stock between the exercise date and the share delivery date, as selected by the holder. Alternatively, the Company may deliver registered Common Stock purchased by the Company in the open market. The Company may also be required to pay cash if it does not have sufficient authorized shares to deliver to the holders upon exercise. Using the Black Scholes pricing model (Level 3), the Company has estimated the fair value of the warrants outstanding as of August 31, 2025 to be $1.00 per warrant. In applying the Black Scholes pricing model (Level 3), the Company utilized the following assumptions: a risk-free interest rate of 2.64%, an expected volatility of 50%, an expected term of 0.05 years, strike price of $0.38 and fair value of Common Stock of $1.38. See Note 26 (Subsequent events) as all outstanding warrants were exercised after the period. Expected volatility is based on both historical and implied volatility of the Company’s common stock.
