This was CNBC's live blog covering European markets.

European markets closed lower Tuesday, as traders in the region continued to digest the latest slew of earnings reports and looked ahead to fresh corporate results stateside.

The pan-European Stoxx 600 fell 0.59%, extending losses through the afternoon as most sectors dropped into the red. Banks and mining stocks remained slightly higher, while travel and leisure stocks slipped 1.62%.

HBSC's London-listed shares added 3.3% after the bank issued a third-quarter earnings report that beat analyst estimates and announced that it will repurchase up to $3 billion in shares.

Shares of Novartis lost 4.7%, despite the company raising its full-year guidance after reporting an uptick in third-quarter sales.

CEO Vas Narasimhan told CNBC Tuesday he was confident the company can retain "consistent growth" by focusing on its range of around 15 blockbuster drugs, even as it steers clear of the GLP-1 weight loss drug market.

Tuesday saw a deluge of other earnings, including from Adidas, Lufthansa, Santander and BP. On the data front, Germany's GfK consumer confidence survey pointed to an uptick in sentiment going into November.

Investors are meanwhile gearing up for a range of possible tax rises in the U.K. Labour government's Wednesday budget.

Asia-Pacific markets traded mixed on Tuesday, while Wall Street indexes were little-changed ahead of a slate of mega-cap technology earnings this week, including Meta Platforms and Microsoft on Wednesday and Apple on Thursday.

The U.K.'s FTSE 100 fell 0.8% ahead of the country's budget announcement Wednesday, while France's CAC 40 and Germany's DAX declined 0.6% and 0.25%, respectively.

Travel stocks, Lufthansa fall as sector faces headwinds

Travel stocks led losses among European sectors in late deals, down 1.5%, with shares of German airline Lufthansa down 4.7%.

The flag carrier on Tuesday reported a 9% year-on-year fall in third-quarter profit and said its earnings position had "deteriorated significantly" across the first nine months of 2024. It said declines were due to price pressures due to higher capacity across the market, various strikes across its group, higher fees and staff costs and delayed aircraft deliveries.

Analysts at Deutsche Bank said it was a "reasonable" update and noted a forecast for a strong demand environment for the rest of winter.

German consumer confidence is set to improve into November and reach its highest level since April 2022 on improving sentiment over household income prospects, fresh survey data showed Tuesday.

The GfK consumer climate index will rise to -18.3 points going into November, ahead of the -20.5 expected by analysts polled by Reuters, and above the slightly revised -21.0 of the previous months.

Novartis CEO says blockbuster drugs to drive 'consistent growth,' with U.S. market in focus

Novartis CEO Vas Narasimhan told CNBC on Tuesday that he was confident the company can retain "consistent growth" by focusing on its range of around 15 blockbuster drugs, even as it steers clear of the GLP-1 weight loss drug market.

"We have the potential to get to top five by the end of the decade," Narasimhan told "Squawk Box Europe." The comments came after the company raised its full-year guidance following strong third-quarter results.

Looking ahead to next week's U.S. presidential election, he said the pharmaceutical industry was urging the "right fixes" from the next administration, regardless of the winner, to ensure legislatures do not "penalize certain types of medication." It comes as drug prices have come under pressure from U.S. regulators.

Adidas reported an uptick in sales and operating profit in its third-quarter results on Tuesday, as the company continued to offload the remaining Yeezy products from its collaboration with musician Ye.

Overall sales rose 7% in euro terms to 6.4 billion euros ($6.9 billion), up from 5.9 billion euros in the same period of last year. Operating profit came in at 598 million euros versus 409 million euros in the third quarter 2023.
