British stocks opened higher on Wednesday, with the FTSE 100 gaining 0.3% as the pound strengthened against a softer dollar. Broader European markets also advanced, with Germany's DAX up nearly 1% and France's CAC 40 rising 0.5%, buoyed by positive corporate updates and a generally upbeat mood among investors.

Energy major BP (LON:BP) dominated headlines, warning of $4 billion to $5 billion in post-tax impairments for the fourth quarter. The charge is tied to its gas and low-carbon energy division, reflecting lower oil and gas prices. However, the company expects net debt to fall to $22-23 billion, aided by $3.5 billion in divestment proceeds.

Other corporate movers included Pearson (LON:PSON), which saw Q4 revenue growth accelerate to 8%, and Frontier Developments (LON:FDEV), which upgraded its full-year guidance after a strong launch for 'Jurassic World Evolution 3'. Conversely, Hays (LON:HAYS) reported a 10% drop in net fees, while Vistry (LON:VTYV) saw home completions fall 9%.
