William Blair analyst Bhavan Suri upgraded Appian to Outperform from Market Perform after attending the company's user conference and speaking to its partners and customers. The analyst believes Appian will benefit from secular tailwinds over the next several years that will drive the stock higher. These include the accelerating pace of digital transformation that will drive increased demand for business applications and the shortage of developers in the market, Suri tells investors in a research note. He sees these factors driving increased Appian usage from new and existing customers.
