Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On April 22, 2026, GridAI Technologies Corp. (the

“Company”) received a letter (the “Letter”) from the Listing Qualifications Department of The Nasdaq Stock Market

LLC (“Nasdaq”) indicating that the Company was not in compliance with the filing of periodic financial reports requirement

for continued listing on The Nasdaq Capital Market, under Listing Rule 5250(c)(1), because the Company has not yet filed its 10-K for

the period ended December 31, 2025.

The Company has 60 calendar days from April 22,

2026, or through June 22, 2026, to submit to Nasdaq a plan to regain compliance with Listing Rule 5250(c)(1). If Nasdaq accepts the Company’s

plan, Nasdaq may grant an extension of up to 180 calendar days from April 15, 2026, or through October 12, 2026, to regain compliance.

If Nasdaq does not accept the Company’s plan, the Company will have the right to appeal such decision to a Nasdaq hearings panel.

The delay in filing the Company’s Annual

Report on Form 10-K is due to the complexity in reviewing the accounting treatment and other information related to the Company’s

recent acquisition of Grid AI Corp. The Company intends to file its Annual Report on Form 10-K as soon as possible, and to submit to Nasdaq,

within the requisite time period, a plan to regain compliance with Listing Rule 5250(c)(1). There can be no assurance that Nasdaq will

accept the Company’s plan or that the Company will be able to regain compliance with Listing Rule 5250(c)(1) or maintain compliance

with any other Nasdaq requirement in the future.

The Company, by filing this Form 8-K, discloses

its receipt of the notification from Nasdaq in accordance with Listing Rule 5810(b).

Item 7.01. Regulation FD Disclosure.

On April 28, 2026, the Company issued a press

release announcing the receipt of Nasdaq notice regarding late 10-K filing. A copy of the press release is furnished herewith as Exhibit
