Financial Performance

Note: Growth rates may differ after conversion to US Dollars.

Senior's revenue was £1.11 billion in 2019 compared to £1.08 billion in the prior year. Senior revenue increased by £14.7 million (1%) with revenue growth in Aerospace and lower revenue from Flexonics year-on-year. Group order intake in 2019 was encouraging, with a book-to-bill of 1.05x. The revenue increase in the Aerospace Division was driven by growth in both civil aerospace and defense markets. Senior was able to mitigate some of the 737 MAX revenue impact through stronger sales on other civil and military program.

Adjusted operating profit decreased by £2.2 million (2%) to £89.4 million (2018 – £91.6 million). Excluding the favorable exchange rate impact of £3.8 million, adjusted operating profit decreased by 6% on a constant currency basis.

Cash held by the company at the end of 2019 decreased to £15.1 million compared to £17 million in the prior year. Cash provided by operations was £115.9 million while cash used for investing and financing activities were £68.7 million and £48.5 million, respectively. Main uses for cash were repayment of borrowings and purchases of property, plant and equipment.


Senior is focused on delivering improved returns for shareholders and is targeting a pre-tax ROCE in excess of 14% over the medium term on a post IFRS 16 basis. Senior benefits from its balance between Aerospace and Flexonics, drawing on shared technology and intellectual property in its fluid conveyance and thermal management businesses. 

Senior is making good progress against its six strategic priorities which were identified as key elements of its business model, underpinning the continued delivery of improved shareholder value: enhance senior's autonomous and Collaborative business model; focus on growth; introduce a high performance operating system; competitive cost country strategy; considered and effective capital deployment; and talent development.

Technology development of the company's composite thermoplastic aerospace ducting product, RT2, has progressed well over the past year as it has advanced composite and component complexity and transitioned from development to production activities. Senior expect product qualification of the first shipset with the launch customer during 2020, with series production ramping up thereafter.
