The Company is, and has been, working diligently to complete its Q2 2021 Form 10-Q as soon as possible; however, due to the high volume of work currently experienced by the advisors to special purpose acquisition companies, the Company is unable to complete and file the Q2 2021 Form 10-Q by the required due date of September 17, 2021 without unreasonable effort and expense. The Company does, however, expect to file such report within five calendar days after the required due date.
