Filtronic, a technology firm based in County Durham, has experienced a dramatic surge in value, with its shares climbing 192% following a significant agreement with SpaceX. The company is now producing essential radar components for Elon Musk's Starlink satellite network, a venture aiming to provide global internet access.

This lucrative partnership has led to substantial financial growth for Filtronic. In the year ending May, its pre-tax profit quadrupled to £13.4 million, and sales increased by 121% to £56.3 million.
