Vodafone Group agrees 8 billion euro sale of Italian business to Swisscom

Vodafone Group on Wednesday confirmed it is in exclusive talks with Swisscom over the sale of its Italian business, and that a deal has been agreed, subject to confirmation, for 8 billion euros ($8.66 billion) on a debt and cash free basis.

The British telecoms firm rejected an updated proposal from France's Iliad to merge their Italian businesses at the end of January. The company had offered Vodafone 6.6 billion euros in cash and 2 billion euros in a shareholder loan.

"Vodafone has engaged extensively with several parties to explore market consolidation in Italy and believes this potential transaction delivers the best combination of value creation, upfront cash proceeds and transaction certainty for Vodafone shareholders," the company said Wednesday of the Swisscom transaction.

It also stressed that the transaction was not certain and that a further announcement would be made in future.

Some of the employees devoted to Apple's EV project will now work on generative AI, the report added.

Apple stock gained 0.5% following the news.

Current market rally can't be compared to the tech bubble, says Citi's Scott Chronert

While it's true that the current bull rally is being propelled by AI- and tech-adjacent stocks, Citi's Scott Chronert disagrees with comparisons to the great Tech Bubble.

"Current multiples are well below '99-'00 levels. Further, our subjective view is that the fundamental circumstance is meaningfully different now vs then," Citi Research's head of U.S. equity strategy wrote.

However, Chronert cautioned that stock fundamentals still have to support the rally in order to sustain his S&P 500 year-end target of 5,100.

"That said, the current spending ramp on gen AI infrastructure and product will need to translate to incremental revenue and growth drivers. But it is premature to judge that," he added. "While the index may overshoot our year-end 5100 target in the short term, it seems premature to increase the probability of our 5700 bull case scenario."
