While Twitter has yet to go public, the company has now effectively reported earnings in the form of an amended S-1 filing. The new version includes Twitter's latest financial data for the third quarter, and the company unsurprisingly continues to put up impressive growth in numerous key metrics.

Ad revenue skyrocketed by 123% to $153.4 million, while the data licensing business notched a minor gain to $15.1 million. Revenue gains aside, Twitter's net loss widened to $64.6 million. Twitter's business isn't scaling yet as it invests heavily in future growth. Research and development expenses jumped to $87.3 million, while sales and marketing expenses came in at $61.2 million.

Monthly active users, or MAUs, continue to grow. Twitter now has 232 million MAUs, and importantly, Twitter just posted some domestic MAU growth. That's good news, because U.S. monetization is dramatically better.
