The operator of Turkey's busiest airport is planning to invest in businesses in the Philippines and Belgrade.

According to Bloomberg News, two people who have knowledge of the confidential information revealed that TAV Havalimanlari Holding AS is in talks to invest in two airport deals that are up for bid in February. One of the people familiar with the issue said Tav, which Aeroports de Paris owns 38 percent stake to, may plan to get operational rights and even asset acquisition. 

The airport in the Philippines would be one of five for which TAV and partners won pre-qualification status last year, the person said, declining to specify a location.

Hurriyet Daily News reported that TAV is part of a consortium that submitted pre-qualification documents for the Philippines' Private-Public-Partnership Regional Airports Projects. TAV wrote a statement to the Public Disclosure Platform (KAP) in August, which states, "The project consists of the operations and maintenance of the Bacolod-Silay, Iloilo, Davao, Laguindingan and New Bohol-Panglao [Tagbilaran] airports, which served around 9 million passengers in 2014."

The Daily Sabah wrote that TAV's statement states that the joint venture of TAV, Aeroports de Paris' (ADP) subsidiary, Aeroports de Paris Management (ADPM), and Metro Pacific investments Corporation (MPIC) applied for the rights to operate and repair airports in Bacolod-Silay, Laguindingan, Iloilo, New Bohol-Panglao, and Davao. The airports mentioned served a total of 9 million passengers in back in 2014. MPIC will own 60 percent share of the consortium, while TAV and ADPM owns 40 percent.

The Nikola Tesla airport in Belgrade hasn't reported any bid documents yet. However, Serbia's government announced in December that it has taken advisers on board to create long-term management contracts.

TAV's shares increased 0.2 percent to 18.03 liras a share in Istanbul January 13. That is the highest it has been since two weeks. It has steadily been increasing for the four days.
