5K Broadcasting Network is a Philippine broadcasting company. Its corporate office is located in Bacolod. 5K operated a number of FM stations across the country via airtime lease agreement under the K5 News FM brand.
The company was established in 2015 by naturopathy and alternative medicine specialist Dr. Ramel Y. Uy as Xanthone Plus Broadcasting Services. DYBZ (whose frequency is owned by RMC Broadcasting Corporation) based in San Jose de Buenavista, Antique was its first station under the Sweet FM brand.
By 2017, XPBS transferred its corporate headquarters and operations to Bacolod and became a partner company of Bandera News Philippines for stations in Western Visayas and Negros Oriental under the Radyo Bandera Sweet FM brand, with the majority of its stations licensed under Fairwaves Broadcasting Network.
In 2021, XPBS rebranded as 5K Broadcasting Network after transferring its Xanthone Plus herbal products to Yes2Health, a company owned by Ramel Uy's younger brother Remelito which would launch its own radio network XFM the following year.
On November 27, 2023, the National Telecommunications Commission (NTC) issued a cease-and-desist order against radio stations that were licensed under Fairwaves Broadcasting Network due to the expiry of its legislative broadcast franchise in 2020. Bandera News Philippines founder Elgin Damasco contended that the affected stations under Fairwaves had their ownership transferred to Palawan Broadcasting Corporation after the latter's franchise renewal was granted in 2021.
By November 2023, 5K Broadcasting ended its partnership with Bandera News. On December 1, all of its stations rebranded as K5 News FM to reflect the change. The following year, it expanded to various markets across the country.
On August 15, 2025, Abante inked an agreement with 5K, where the former will air a number of programs from its eponymous radio station, along with Bilyonaryo News Channel's newscast Agenda, on selected K5 News FM stations.
