History of Signature Aviation can trace its origins back to a small industrial belting works founded in Scotland in 1879. Over time, and known as the BBA Group, the company grew its operations to include a wide range of specialist industrial and automotive products before becoming involved in aviation. In 2006, with the demerger of its materials technology division, Fiberweb, the BBA Group became a focused aviation support and aftermarket services business and was renamed BBA Aviation. In 2016, BBA Aviation acquired Landmark Aviation, significantly boosting its core Signature Flight Support FBO business and, at the end of 2019, following the sale of its aftermarket services business, Ontic, the group was renamed Signature Aviation to reflect its key focus on serving the Business & General Aviation (B&GA) market through Signature. On 1 June 2021, Signature Aviation was acquired by Blackstone, Global Infrastructure Partners and Cascade.

Industrial and automotive products For its first thirty years the company's main product was solid woven belting used for power transmission and mechanical conveying in industries such as mining. The company's manufacturing interests then grew to include a wide range of industrial and automotive products, sold around the world. These included the transmission linings used on the Model T Ford motor car; materials for Spitfire, Hurricane and Typhoon aircraft; and, later, the first brake pads fitted to Jaguar production cars. By the early 1980s the BBA Group, the holding company created in 1967 and now mostly focused on automotive and friction materials, was the world's largest supplier of original equipment brake pads to the automotive industry. Aviation & nonwovens In 1986, BBA Group made its first major move into aviation by acquiring the UK based landing gear and hydraulics business APPH and a similar business in the US. It also acquired its first nonwoven fabrics business by buying a part share in US-based Reemay. Throughout the 1990s BBA Group continued to grow its aviation and nonwovens portfolio. In 1992 Signature Flight Support was formed through the merger of Page Avjet, an executive aircraft interiors business, and Butler fixed base operations. BBA Group took full ownership of Signature in 1996. Concurrently, BBA acquired more nonwoven manufacturers including Fiberweb Group in the USA and Europe. By 1997 BBA was focused on two major divisions: Aviation and Materials Technology (nonwoven fabrics and friction materials). BBA continued to acquire fixed base operations (FBOs) to add to the Signature network and moved into jet engine repair and overhaul through the acquisition of H+S Aviation in the UK and UNC Airwork in the US in 1998. In 2000, the automotive friction materials division was sold and BBA moved from the Engineering to the Transport sector on the . ASIG, a business supplying flight support services to the commercial aviation market was acquired in July 2001. BBA Aviation In November 2005, BBA Group announced that it intended to separate its two businesses by the sale of its Materials Technology division. The demerger was completed in November 2006 and the remaining aviation- focused business was renamed BBA Aviation. The company also acquired Ontic, a legacy aerospace parts and components business, during the year. In 2007, Simon Pryce joined BBA Aviation as its new Group Chief Executive. From 2007 BBA Aviation continued to grow the Signature network via acquisition and through the Signature SelectTM licensing model which was launched in 2012. ASIG also continued to grow through acquisition and contract wins. Ontic acquired GE Aviation Systems' fuel measurement business in 2011, strengthening its position in the UK with a new facility at Cheltenham. APPH was sold to Héroux-Devtek Inc in 2014. In 2016, BBA Aviation announced the successful completion of the acquisition of Landmark Aviation, a leading provider of specialist B&GA support services, adding 62 locations to the Signature network. Landmark Aviation was acquired from , in a deal worth over $2 billion, marking a transformational moment for BBA Aviation, Signature Flight Support and the general aviation industry. In the same year, Ontic continued the expansion of its product offering through the acquisition of a portfolio of legacy avionics parts from GE Aviation. In January 2017 BBA Aviation completed the sale of ASIG and announced the creation of Gama Aviation Signature Aircraft Management, a partnership between Gama Aviation and Signature, and one of the largest aircraft management and charter businesses in the world. On 1 March 2018 BBA Aviation announced that it was conducting a strategic review of its engine repair and overhaul (ERO) business and, at the end of May 2018, management committed to a plan to sell substantially all of the business and the relevant assets and liabilities were classified as held for sale. Mark Johnstone was appointed Group Chief Executive of BBA Aviation on 1 April 2018. In July 2018, BBA Aviation completed the acquisition of EPIC Aviation, a company providing fuel and fuel related services at more than 200 privately owned branded FBOs, over 120 unbranded FBOs, fuel cards and transaction processing. The EPIC ‘non-owned’ asset-lite franchise model operates separately to the Signature ‘owned’ model and the Signature SelectTM network of non-owned locations moved to the EPIC management team. At the end of 2018 BBA Aviation completed the acquisition of Firstmark Corp – a provider of proprietary components and subsystems for the aerospace and defence industries – which was added to the Ontic portfolio. Signature Aviation On 1 November 2019, BBA Aviation completed the sale of Ontic to CVC for effective proceeds of $1.321 million and announced a special dividend to shareholders totaling $835 million. With the process to sell the ERO business ongoing, the Board also elected to rename the group Signature Aviation to better align it with its most significant brand in its core market. The group began trading on the London Stock Exchange as Signature Aviation plc on 25 November 2019. On 5 February 2021 Signature Aviation announced that the Board had accepted and was recommending to shareholders a joint offer for the company from Global Infrastructure Partners, Blackstone and Cascade (Signature Aviation’s largest shareholder). The offer was approved by shareholders on 18 March 2021 and the transaction completed on 1 June 2021. On 17 February 2021 the company announced that it had reached agreement with StandardAero, a portfolio company of The Carlyle Group (Carlyle), on the terms of sale of the ERO businesses (Dallas Airmotive, H+S Aviation, ITS, BTEC and IGS).
