Twitter IPO: By the Numbers

Updated from 6:12 P.M. to include ownership stakes.

NEW YORK (TheStreet) -- Twitter has filed its S-1 with the Securities and Exchange Commission, announcing its plans to go public.

The San Francisco-based microblogging site led by CEO Dick Costolo, could raise up to $1 billion, a number that for now, is just a placeholder used to calculate fees.

According to the filing, Twitter's revenue in 2012 totaled $316.9 million. The company's revenue for the first six months of 2013 totaled $253.6 million, the filing said.

The U.S. still accounts for much of Twitter's revenue, as international revenue for 2012 was only $53 million. For the first six months of 2013, international revenue was $62.8 million, accounting for 25% of total revenue during that time frame. The social network noted that it recently focused on international spending in certain countries, including Australia, Brazil, Canada, Japan and the United Kingdom.

Twitter noted that revenue grew by 198% from 2011 to 2012, while net loss decreased by 38% to $79.4 million. During that same time frame, adjusted EBITDA increased by 149% to $21.2 million.

From the first six months of 2012 to the first six months of 2013, revenue increased 107%, and adjusted EBITDA increased by $20.7 million to $21.4 million. The company's net loss increased by 41% to $69.3 million.

The majority of Twitter's revenue, 87% for the six months ended June 30, comes from advertising in the form of three Promoted Products: Promoted Tweets, Promoted Accounts and Promoted Trends. Twitter noted that 85% of its fiscal 2012 revenue was derived from advertising.
