Amendment Description	This Amendment No. 1 on Form 10-K/A (this “Amendment”) amends the Annual Report on Form 10-K for the fiscal year ended June 30, 2022 of Bitmis Corp. (now known as Cambell International Holding Corp.) (the “Company”), originally filed with the U.S. Securities and Exchange Commission (“SEC”) on July 19, 2022 (the “Original Report”). The purpose of this Amendment is to accurately reflect on the cover page of the Original Report that the Company does not have any securities registered under Section 12(g) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).In addition, this Amendment reflects that the Company is not required to file reports pursuant to Section 13 or Section 15(d) of the Exchange Act. The fiscal year in which the Company’s registration statement was declared effective ended on June 30, 2017. No shares were sold pursuant to that registration statement. The Company’s reporting obligation under Section 15(d) of the Exchange Act was automatically suspended as of July 1, 2017 as it had fewer than 300 shareholders of record. The Company has been filing periodic reports on a voluntary basis, and continues to do so.This Amendment further reflects that the Company qualifies as an emerging growth company as it consistently has had total annual gross revenues of less than $1.235 billion and none of the events that would cause termination of its status as an emerging growth company has occurred.This Amendment does not amend, modify or otherwise update any other information in the Original Report. Accordingly, this Amendment should be read in conjunction with the Original Report. In addition, this Amendment does not reflect events that may have occurred subsequent to the date of the Original Report.
