Conclusion regarding the effectiveness of disclosure controls and procedures

Our President and Chief Executive Officer (our principal executive officer) and Vice President - Finance and Chief Financial Officer (our principal financial officer) each have evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this Form 10-Q. Based on such evaluation, and as of such date, our President and Chief Executive Officer and Vice President - Finance and Chief Financial Officer concluded that our disclosure controls and procedures were effective in all material respects.

Changes in internal control over financial reporting

Other than the events discussed under the section entitled "P3 Technologies, LLC Acquisition" below, there has been no change to our internal control over financial reporting during the quarter covered by this Form 10-Q that has materially affected, or that is reasonably likely to materially affect, our internal control over financial reporting.

P3 Technologies, LLC Acquisition

On November 9, 2023, we acquired P3, a privately-owned custom turbomachinery engineering, product development, and manufacturing business that serves the space, new energy, defense, and medical industries. For additional information regarding the acquisition, refer to Note 2 to the Unaudited Condensed Consolidated Financial Statements included in Part I, Item 1 in this Form 10-Q and Management's Discussion and Analysis of Financial Condition and Results of Operations included in Part I, Item 2 in this Form 10-Q. Based on the recent completion of this acquisition and, pursuant to the SEC's guidance that an assessment of a recently acquired business may be omitted from the scope of an assessment for a period not to exceed one year from the date of acquisition, the scope of our assessment of the effectiveness of internal control over financial reporting as of the end of the period covered by this report does not include P3.

We are in the process of implementing our internal control structure over P3 and we expect that this effort will be completed during the fiscal year ending March 31, 2025.
