Amendment Description	On March 17, 2022, BK Technologies Corporation (the “Company”) filed, with the Securities and Exchange Commission (the “SEC”), its Annual Report on Form 10-K for the year ended December 31, 2021 (the “Report” or “Form 10-K”). This Amendment No. 1 (this “Amendment”) corrects a typographical error in the numbering of the various items in Form 10-K and also updates Part III of the Report to contain certain additional information required therein. Except for corrections to the item numbering, the changes to Part III and the filing of related certifications added to the list of Exhibits in Part IV, this Amendment makes no other changes to the Form 10-K. This Amendment does not amend, update, or change the financial statements or any other items or disclosures contained in the Report and does not otherwise reflect events occurring after the original filing date of the Report. Accordingly, this Form 10-K/A should be read in conjunction with the Company’s filings with the SEC subsequent to the filing of the Report. As described in Part I, Item 1 of the Report, on March 28, 2019, we implemented a holding company reorganization (the “Reorganization”). The Reorganization created a new holding company, BK Technologies Corporation, which became the new parent company of BK Technologies, Inc. BK Technologies Corporation’s only significant assets are the outstanding equity interests in BK Technologies, Inc. and any other future subsidiaries of BK Technologies Corporation. The Reorganization was intended to create a more efficient corporate structure and increase operational flexibility.  For the purpose of this Amendment, references to “BK Technologies,” the “Company,” “we,” “us,” or our management or business at any period prior to the Reorganization (March 28, 2019) refer to those of BK Technologies, Inc. as the predecessor company and its subsidiaries, and thereafter to those of BK Technologies Corporation and its subsidiaries, except as otherwise specified or to the extent the context otherwise indicates.
