At a time when many large mergers are being blocked or delayed by regulators, Cisco Systems Inc. (Nasdaq: CSCO) took just six months to close its $28 billion acquisition of Splunk.

Cisco announced the acquisition of software maker Splunk in September 2023. The deal is an attempt to diversify Cisco’s business, giving it more services to sell to corporate customers, including tools that monitor network health and cybersecurity risks, Bloomberg News reported. Cisco’s traditional business of selling networking hardware to businesses has been dogged by a slowdown in tech spending. Regulators in multiple countries are increasingly skeptical of larger acquisitions, particularly by major tech companies seeking to move into adjacent markets.
