Jeff Lawson, founder, CEO and chairman of Twilio, speaks at a press conference during the Mobile World Congress on March 1, 2017 in Barcelona, Spain

Cloud communications company Twilio just re-reported its full-year forecast, after the company messed up the math the first time around.

Twilio's full-year earnings per share guidance is now expected to between 12 cents and 13 cents, instead of the 16 cents to 17 cents originally reported alongside its third-quarter earnings.

The company said in a filing the change is "due to a calculation error."

It appears the company just didn't add up the quarterly earnings correctly for fiscal 2019 when issuing the guidance last week. Twilio said last week it sees fourth-quarter earnings between 1 cents and 2 cents. It also reported last week 3 cents a share in non-GAAP earnings for the third quarter. It earned 5 cents a share and 3 cents a share in the first and second quarters, respectively. Those four-quarter earnings add up to a range of between 12 and 13 cents, the new guidance put out Monday.
