IMPORTANT NOTICES

Important Notice Regarding Forward-Looking Statements

This Current Report on Form 8-K contains certain “forward-looking statements” within the meaning of the Securities Act of 1933 and the Securities Exchange Act of 1934, both as amended. Statements that are not historical facts, including statements about Quetta Acquisition Corporation’s (the “Company”) ability to regain compliance with Nasdaq’s continued listing standards, the Company’s intentions to monitor its market value of listed securities, potential actions to regain compliance, and the possible outcomes with respect to Nasdaq’s continued listing determination, are forward-looking statements. Words such as “expect,” “believe,” “estimate,” “intend,” “plan,” and similar expressions indicate forward-looking statements.

These forward-looking statements are not guarantees of future performance and are subject to various risks and uncertainties, known and unknown, that could cause actual results to differ materially from those expressed or implied by such statements. These risks and uncertainties include, but are not limited to: (i) the Company’s ability to regain compliance with Nasdaq’s continued listing requirements within the applicable compliance period; (ii) the potential delisting of the Company’s securities from Nasdaq; (iii) the Company’s ability to obtain approval for or complete a transfer of its securities to The Nasdaq Capital Market; (iv) the Company’s ability to execute its business strategy; and (v) other risks and uncertainties described in the Company’s filings with the Securities and Exchange Commission.

Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may differ materially from those indicated by the forward-looking statements. The Company cautions you not to place undue reliance on these forward-looking statements. Forward-looking statements speak only as of the date of this Current Report on Form 8-K, and the Company undertakes no obligation to update or revise any such statements, except as required by law.

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

Quetta Acquisition Corporation (the “Company”), as previously disclosed in its Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on April 10, 2026, received written notice from the Listing Qualifications Department (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) on April 6, 2026 stating that the Staff had determined to delist the Company’s securities due to the Company’s failure to regain compliance with the minimum Market Value of Listed Securities (“MVLS”) requirement. In addition, the Company does not satisfy the continued listing requirement of at least 400 total holders under Nasdaq Listing Rule 5450(a)(2), which constitutes a separate and independent basis for delisting. The Company has requested a hearing before a Nasdaq Hearings Panel.

On April 20, 2026, the Company received an additional written notice from Nasdaq stating that, because the Company had not yet filed its Annual Report on Form 10-K for the fiscal year ended December 31, 2025, the matter serves as an additional basis for delisting the Company’s securities from Nasdaq.

Nasdaq further informed the Company that the Company must notify the Hearings Panel by April 27, 2026 that it intends to address this matter at its previously scheduled hearing on May 14, 2026 in order to obtain a stay of the suspension of trading of the Company’s securities pending the Panel’s decision.

On April 21, 2026, the Company notified the Hearings Panel that it intends to address this matter at the hearing.

The Company intends to file its Annual Report on Form 10-K as soon as practicable. However, there can be no assurance that the Panel will grant the Company’s request for continued listing or any stay, or that the Company will regain compliance with all applicable listing standards.
