Twitter Inc. (NYSE:TWTR) shares were downgraded by Evercore ISI to Hold from Buy Thursday. The firm also cut Twitter’s price target to $39 per share from $49, expressing concerns about the social media site’s slow user growth.

“We no longer have the same conviction we once did that Twitter under-monetizes on the basis of its overall influence, the result is a more conservative view of valuation and the company’s long-term growth prospects,” Ken Sena, analyst at Evercore ISI, said in a research note Thursday.

Still, shares of Twitter, which have lost 11 percent of their value since its IPO in November 2013, added nearly 2 percent Thursday to $37.71 in morning trading.

The report comes a day after Twitter's annual shareholder meeting in San Francisco. Investor Chris Sacca, a former adviser to Twitter who invested in the company through his own firm, Lowercase Capital LLC, published a 8,500-word essay on “What Twitter Can Be,” arguing the company has “failed to tell its own story.”

Sacca also didn’t shy away from saying which technology company Twitter would be a good fit with in a merger scenario. “I think it would be a fantastic use of Google’s cash,” Sacca said on CNBC Wednesday.
