ROME, June 13 (Reuters) - Stellantis on Thursday said it will pay at least 7.7 billion euros ($8.32 billion) in dividends and buyback by 2024, as it confirmed its financial guidance and capital return plan for the year.

Ahead of its Investor day, the carmaker said adjusted operating income margin would be between 10-11% in the first half of the year and "industrial free cash flows visibly below the prior year period".
