Salesforce Inc. has agreed to buy Informatica Inc. for about $8 billion, sealing the deal on a software firm that had seen its shares plunge by as much as 59% since the companies’ first talks failed last year.

Salesforce has acquired cloud data management firm Informatica in an $8 billion equity deal, marking a major move in its push to strengthen its AI and data infrastructure capabilities.

Salesforce says the acquisition will help the San Francisco software company, which provides tools to help businesses manage sales and customer data, ramp up its AI efforts.
