Conclusions of Management Regarding Effectiveness of Disclosure Controls and Procedures

At the end of the period covered by this Quarterly Report on Form 10-Q, an evaluation was carried out under the supervision and with the participation of the Company’s management, including the Principal Executive Officer (“PEO”) and Principal Financial Officer (“PFO”), of the effectiveness of the design and operations of the Company’s disclosure controls and procedures (as defined in Rule 13a – 15(e) and Rule 15d – 15(e) under the Exchange Act). Based on that evaluation, the PEO and the PFO have concluded that our disclosure controls and procedures were not effective in ensuring that: (i) information required to be disclosed by the Company in reports that it files or submits to the SEC under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in applicable rules and forms, and (ii) material information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to our management, including our PEO and PFO, as appropriate, to allow for accurate and timely decisions regarding required disclosure.

Management of the Company believes that these material weaknesses are more so due to the small size of the Company’s accounting staff. To continue to address this matter, in 2025 and 2026, the Company hired employees to lead Sarbanes-Oxley compliance, SEC reporting, accounts payable, payroll, finance and accounting in Mexico, information technology, and the joint venture. In addition, the Company hired a third-party firm in 2025 to assist with the implementation of new accounting software and to assist with gaining compliance with Sarbanes-Oxley, all of which is expected to be completed in 2026.
