Terms of the transaction, which is expected to close in the coming weeks, were not disclosed.
The acquisition "will help strengthen the insights, products and data that we provide to our clients throughout the world," said Mike Chinn, president of S&P Global Market Intelligence and executive vice president of technology and innovation at S&P Global.
"Panjiva provides clients with macro data covering 95 percent of global trade flows, as well as transactional data covering 35 percent of global trade flows," S&P said. "The company tracks supply data from retailers, exporters and shippers across a myriad industries and commodities."
In a letter posted on Panjiva's website, the company's founders - Josh Green, chief executive officer and James Psota, chief technology officer - said, "When we got started, 'Big Data; wasn’t a thing. Today, it seems that everyone’s talking about leveraging data to make better decisions. But the truth is, global industry is in the earliest stages of figuring out how best to make use of data."
S&P said the acquisition of Panjiva is expected to be profitable in 2019 (excluding integration costs), but that given the transaction’s modest size, it is not expected to have a material impact on S&P's adjusted earnings per share in 2018.
