Univision Communications, the largest Spanish-language media company in the U.S., has filed for an initial public offering.

The company said the number of shares to be offered and the price range for the proposed IPO have not yet been determined. Univision’s move to go public has long been expected.

Univision’s owners include Saban Capital Group, Texas Pacific Group (TPG), Thomas H. Lee Partners, Providence Equity Partners, Televisa and Madison Dearborn Partners.

Morgan Stanley, Goldman Sachs & Co. and Deutsche Bank Securities Inc. are lead book-running managers for Univision’s proposed offering.

In 2014, Univision generated $2.9 billion in revenue and posted net income of $900,000, respectively.

Also Thursday, Univision announced an amended agreement with Mexican media company Televisa, extending Univision’s exclusive U.S. broadcast and digital rights to Televisa programming from its current expiration date of at least 2025 to at least 2030.

Univision’s deal with Televisa also revised royalty-rate structure, under which Univision will pay 11.84% versus 11.91% previously. On Jan. 1, 2018, licensing fees are set to increase to 16.13%, compared with 16.22% under the prior terms.

Univision operates two broadcast TV networks — Univision Network and UniMás — plus nine cable networks: Galavisión, Univision Deportes, De Película, De Película Clásico, Bandamax, Ritmoson, Telehit, Univision tlnovelas and ForoTV. The company owns and operates 60 TV stations in the U.S. and Puerto Rico, along with 62 radio stations in the U.S. and five in Puerto Rico.

Its digital properties include Univision.com, UVideos and Flama. Univision has made strategic investments in filmmaker Robert Rodriguez’s El Rey Network and with Disney’s ABC News in Fusion, a TV and digital news network aimed at millennials.

In its S-1 filing, Univision said that there are more than 57 million U.S. Hispanics, representing more than 17% of the total population. America’s Hispanic population is projected to top 77 million by 2030, to comprise nearly 22% of the total U.S. population.

Univision disclosed in the SEC filing that CEO Randy Falco had a base salary of $1.75 million in 2014, with a target bonus of $2.9 million and options worth $699,974 based on a valuation of $264.40 per share.
