OVERVIEW In 1979, our co-founders, Mr. Alan Lee Klapmeier and Mr. Dale Edward Klapmeier started developing the VK-30 homebuilt aircraft in Wisconsin, the United States. The Klapmeier brothers established Cirrus Design in 1987, following which the VK-30 aircraft celebrated its first flight in 1988. The headquarters of Cirrus Design was relocated to Duluth, Minnesota, the United States in 1994, and Legacy Cirrus Industries was incorporated in 1996. In June 2011, Legacy Cirrus Industries was acquired by CAIGA by way of merger. Upon completion of the merger in June 2011, Legacy Cirrus Industries became indirectly wholly-owned by CAIGA. In preparation of our Listing, we underwent the Reorganization and our Company was incorporated in the Cayman Islands as an exempted company with limited liability in December 2019. Our Company is an investment holding company and our Group carries out our operations mainly through our wholly-owned subsidiaries. Since our inception in 1984, we have grown to become a pioneer and a global market leader in the personal aviation industry, according to Frost & Sullivan. Our two aircraft product lines are the SR2X Series (SR20, SR22 and SR22T models) and the Vision Jet.

Upon its incorporation, one ordinary Share of par value of US$1.00 per Share was allotted and issued to the initial subscriber, an independent third party, on December 13, 2019, which was then transferred to CAIGA Hong Kong, a direct wholly-owned subsidiary of CAIGA, on the same date. On January 15, 2020, an additional 155,481,658 ordinary Shares were issued to CAIGA Hong Kong. For details, see “— Reorganization — 2. Acquisition of CAIGA Co., Ltd. through Share Swap.” Our Company has been wholly-owned by CAIGA Hong Kong since the date of its incorporation. Our Principal Subsidiaries Set out below are the major corporate history and shareholding changes of our principal subsidiaries: Cirrus Industries and Legacy Cirrus Industries Legacy Cirrus Industries was incorporated in Delaware, the United States, as a corporation on February 13, 1996. Upon the inception of Legacy Cirrus Industries, it was owned by the Klapmeier family as to approximately 28.49%, with the remaining shareholding held by 20 other stockholders who were initial investors of the Group, each, to the best knowledge of the Company, an independent third party save for their then equity interest in Legacy Cirrus Industries. Over the years, with additional fundraising and the grant of share incentives to employees, the shareholding structure of Legacy Cirrus Industries had become more dispersed. As of August 2001, it was owned by the Klapmeier family as to approximately 39.53%, with the remaining shareholding held by 402 other stockholders including employees and, to the best knowledge of the Company, other independent third parties (save for their then equity interest in Legacy Cirrus Industries) including funds, investment companies and other individuals. In August 2001, Cirrus Holding Company Limited (“Arcapita Holdco,” an independent third party established by Arcapita, an asset management firm headquartered in Bahrain) acquired majority stake in Legacy Cirrus Industries by capital injection. As of February 2011 and immediately before the 2011 Merger (as defined below), Legacy Cirrus Industries was owned by Arcapita Holdco as to approximately 58.80%, by the Klapmeier family as to approximately

13.98%, with the remaining shareholding held by 499 other stockholders including employees and, to the best knowledge of the Company, other independent third parties including funds and investment companies. HISTORY, REORGANIZATION AND CORPORATE STRUCTURE – 153 – To the best knowledge of the Company, following the global financial crisis in 2008, Arcapita was seeking to exit its investment in the Group. Considering the Group’s long-term development potential in light of its product offering, reputation in the personal aviation industry and management team’s expertise, CAIGA decided to acquire the Group by way of a merger with Legacy Cirrus Industries. CAIGA is a limited liability company incorporated in the PRC and is principally engaged in the research and development, operation and service of general aviation, designing and manufacturing of aviation parts and accessories. For further details on the background of CAIGA, see the section headed “Relationship with Our Controlling Shareholders — Background of Our Controlling Shareholders.” Pursuant to an agreement and plan of merger dated February 3, 2011 (the “Merger Agreement”), CAIGA MS Co., Ltd., a direct wholly-owned subsidiary of CAIGA (US) Co., Ltd. (a company directly wholly-owned by CAIGA Co., Ltd., which was wholly-owned by CAIGA prior to the Reorganization), merged with and into Legacy Cirrus Industries (the “2011 Merger”). The aggregate consideration for the 2011 Merger pursuant to the Merger Agreement was calculated by the valuation of the Group (i.e., US$210 million), as adjusted and deducted by the net debt and certain deductibles of the Group (i.e., approximately US$150 million), as well as the transaction expenses of the 2011 Merger. The valuation of the Group was determined based on advice provided by independent financial advisors to the 2011 Merger. Pursuant to the Merger Agreement, on or before the effective date of the 2011 Merger, CAIGA (US) Co., Ltd. shall deposit the consideration payable to the then stockholders of Legacy Cirrus Industries in cash with a paying agent who shall make payments to the then stockholders. The certificate of merger in respect of the 2011 Merger was filed with the Secretary of State of the State of Delaware on June 24, 2011, and the 2011 Merger became effective on the same day. The 2011 Merger has been properly and legally completed and settled with all applicable approvals obtained. Based on (i) certain confirmations provided by Cirrus Industries and CAIGA and (ii) Hogan’s review of (A) the clearance letter issued by the CFIUS in connection with the 2011 Merger and (B) the national security agreement entered into among Legacy Cirrus Industries, CAIGA and the U.S. Department of Defense (on behalf of CFIUS) as a condition of CFIUS’ clearance of the 2011 Merger (the “NSA”), Hogan confirms that CFIUS cleared the 2011 Merger and that Cirrus Industries, Legacy Cirrus Industries and CAIGA have complied with the terms of the NSA. Upon the completion of the 2011 Merger, CAIGA was held by AVIC as to 70%, by Guangdong Utrust Investment Holding Co., Ltd.* ( , “Guangdong Utrust”) as to 14%, by Guangdong Hengjian Investment Holding Co., Ltd.* ( , “Guangdong Hengjian”) as to 10% and by Zhuhai Gree Aviation Investment Co., Ltd.* ( , “Gree Aviation Investment”) as to 6%. Subsequent to the 2011 Merger, Legacy Cirrus Industries had been directly wholly-owned by CAIGA (US) Co., Ltd. until the merger in December 2022 as further elaborated in “— Reorganization — 3. Merger of holding entities under the 2022 Merger” below (the “2022 Merger”), after which Cirrus Industries (the surviving corporation pursuant to the 2022 Merger among Legacy Cirrus Industries, CAIGA (US) Co., Ltd. and CAIGA Co., Ltd.) became wholly-owned by our Company. Subsequent to the 2011 Merger when the Group became indirectly HISTORY, REORGANIZATION AND CORPORATE STRUCTURE – 154 – wholly-owned by CAIGA, each of Mr. Alan Lee Klapmeier and Mr. Dale Edward Klapmeier ceased to hold any interest in the Group. Mr. Alan Lee Klapmeier ceased to hold any executive position in the Group since 2009 to pursue other opportunities while Mr. Dale Edward Klapmeier ceased to hold any executive position in the Group following his retirement in 2019. Cirrus Design Cirrus Design was incorporated in Wisconsin, the United States, as a corporation on February 25, 1987, with Mr. Alan Lee Klapmeier, Mr. Dale Edward Klapmeier and Mr. Jeffrey K Viken, each an independent third party, as the initial shareholders. The principal business activity of Cirrus Design is designing, manufacturing and retail sale of aircraft and related operations. Cirrus Design is the principal operating company within our Group. While the entire shareholding held by Mr. Jeffrey K Viken was repurchased by Cirrus Design in April 1990, Mr. Alan Lee Klapmeier and Mr. Dale Edward Klapmeier transferred the entire shareholding in Cirrus Design to Legacy Cirrus Industries in February 1996, after which Cirrus Design became wholly-owned by Legacy Cirrus Industries. After the 2022 Merger, CAIGA Co., Ltd. (subsequently renamed as Cirrus Industries) became the shareholder of Cirrus Design. As of the Latest Practicable Date, the authorized capitalization of Cirrus Design was 100,000 shares of common stock with par value of US$0.01 per share, and the issued and outstanding share capital of Cirrus Design was 82,500 shares of common stock with par value of US$0.01 per share, all of which was held by Cirrus Industries.
