Shares of British defence contractor Babcock surged more than 10% after the company announced an unexpected share buyback program and raised its medium-term growth forecast.

The London-listed company met expectations for financial year 2025 with sales of £4.831 billion ($6.58 billion) and marginally beat earnings estimates with £363.9 million adjusted profit, according to FactSet compiled data.

Babcock, which makes Type 31 frigates for the U.K.'s Royal Navy, said that, as it is flush with cash and had lowered its debt ratio sufficiently, it was returning money to shareholders through a £200 million share buyback that will be expected over the current financial year.

"This is completely unexpected and we think it will be very well received by investors," said JPMorgan analyst David Perry, in a note to clients.

The stock is up more than 115% over the past year. Even after Wednesday's stock rally, the Wall Street bank analyst say shares could rise a further 17% to £1.37 over the next 12 months.

Babcock also raised its medium-term profit margin growth forecast to 9%. The company said it is expecting to achieve underlying operating profit margins of 8% in the 2026 financial year, earlier than planned.

Chief Executive David Lockwood told analysts that the company is well-positioned to capitalize on Europe's defence rearmament drive. "I think it's clearly a new era for defense if you look at what's going on at NATO," Lockwood said in an earnings call, according to FactSet.

"For companies like Babcock, when you have declining budgets, which we've had for most of my working life, the industry is somewhere where you make cost savings," he added.

Lockwood added that "the various conflicts around the world will feel unstable. Governments will feel the need to look after their citizens."

"I had to wait to my sixties to become cool as a business leader because it's now cool to be in defense is amazing the way we actually matter and people recognize we matter," he added.

Good morning from London, and welcome to CNBC's live blog covering European financial markets action on Wednesday, and the latest regional and global business news, data and earnings.

Futures data from IG suggests a positive start for European markets, with London's FTSE looking set to open unchanged at 8,764, Germany's DAX up 0.2% at 23,699, France's CAC 40 flat at 7,625 and Italy's FTSE MIB also up 0.3% at 39,673.

Global market sentiment rose Tuesday on bets that the ceasefire between Iran and Israel could last, after a shaky start to the truce that saw President Donald Trump lambast both countries for violations.

Traders are also digesting the latest comments from the U.S. Federal Reserve Chair Jerome Powell, who said Tuesday that the central bank was committed to keeping inflation in check, and would likely keep rates steady until there's more clarity on how trade tariffs might affect prices.

Powell said policymakers were "well positioned to wait to learn more about the likely course of the economy before considering any adjustments to our policy stance."
