(&#8220;Mesa&#8221;) had completed its Annual Report on Form 10-K for the fiscal year ended September 30, 2019 (the &#8220;2019 10-K&#8221;) and instructed its third party printer service (the &#8220;Printer&#8221;) to file the 2019 10-K with the Securities and Exchange Commission (the &#8220;SEC&#8221;) prior to the submission deadline on December 16, 2019. Due to unforeseen technical problems arising at the Printer, the Printer was unable to carry out Mesa&#8217;s instructions and so the 2019 10-K could not be filed with the SEC by the 5:30 P.M. EDT submission deadline without unreasonable effort or expense to Mesa. Mesa filed the 2019 10-K shortly after the submission deadline and such filing was accepted at 6:20 P.M. EDT on December 16, 2019.</p>
