Will Twitter’s Q1 earnings meet Wall Street expectations?

Wall Street will soon learn whether Twitter CEO Dick Costolo’s recent efforts to turn Twitter into Facebook is working.

Costolo has been furiously rolling out tweaks to the micro-blogging site in an effort to attract so-called monthly active users, a measure of users that is closely watched by Wall Street.

Shareholders will learn Tuesday when Costolo & Co. report first-quarter earnings for the three months after the closing bell.

Analysts generally expect the company to report a net loss of 3 cents a share on revenue of $241.7 million.

Even if revenue exceeds expectations, all eyes will be on engagement, following the stock plunge after Twitter’s fourth-quarter results.

In February, Twitter said revenues beat expectations, but investors sent the stock plunging on concerns of slowing user growth.

Shares of Twitter are down 36 percent this year on the social-media company’s 241 million monthly active users reported last quarter, up just 3.8 percent from previous quarter.

“User growth . . . and engagement are top of mind,” said Youssef Squali of Cantor Fitzgerald.

Squali is predicting monthly active users of 255 million, an increase of 24.8 over last year, but just 5.5 percent over the previous quarter.
