Welcome to our dedicated page for Spirit Aerosys SEC filings (Ticker: SPR), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
This page compiles historical SEC filings for Spirit AeroSystems Holdings, Inc. (former NYSE: SPR), which became a wholly owned subsidiary of The Boeing Company on December 8, 2025. These documents trace Spirit’s evolution as a public aerostructures manufacturer through its final days as an independent registrant and provide detailed insight into its commercial, defense and aftermarket businesses.
Key filings include Forms 10‑K and 10‑Q, where Spirit reported segment results for Commercial, Defense & Space and Aftermarket operations, disclosed backlog tied to Boeing and Airbus programs, and discussed risks such as supply chain fragility, program‑specific forward losses and liquidity constraints. Earnings‑related Forms 8‑K furnish press releases on quarterly and annual results, including information on changes in estimates, excess capacity costs and customer advances.
For corporate events, multiple Form 8‑K filings describe the Agreement and Plan of Merger with The Boeing Company, the stock and asset purchase agreement with Airbus SE for Airbus‑related businesses, and the share purchase agreement with CTRM for the Subang, Malaysia facility. Additional 8‑Ks address the sale of Fiber Materials Inc., amendments to bridge and term loan credit agreements, and litigation developments in the Delaware Court of Chancery.
Two filings mark the end of SPR as a listed and reporting company: a Form 25 filed by the New York Stock Exchange on December 8, 2025 to remove Spirit’s Class A common stock from listing and registration under Section 12(b), and a Form 15 filed on December 18, 2025 terminating registration under Section 12(g) and suspending reporting obligations under Sections 13 and 15(d). Together, they confirm SPR’s transition from a public issuer to a Boeing subsidiary.
On this page, users can access these historical filings and rely on AI‑generated summaries to quickly understand complex disclosures, from merger mechanics and debt amendments to segment performance and risk factors. While insider transaction reports such as Form 4 are part of the broader SEC record, post‑merger governance and compensation details for Spirit’s operations are now reflected within Boeing’s consolidated filings rather than under the SPR ticker.
