Ten MAI-listed companies have met the criteria to upgrade to a listing on the Stock Exchange of Thailand, with three set to leave the smaller bourse soon.
Mono Technology, a leading entertainment content provider, and Asian Phytoceuticals (APCO) are two of the three companies, said Market for Alternative Investment president Prapan Charoenprawatt.
The MAI, a bourse for small companies, will lose 10 billion baht in market capitalisation after the three companies move to trade on the SET, Mr Prapan said.
As of Tuesday, the MAI's market value was 426.53 billion baht.
According to the SET's criteria, any companies applying to list on the main board must have paid-up capital of at least 300 million baht and a minimum market capitalisation of 5 billion baht.
Other requirements include a combined minimum net profit from operations of 50 million baht over the past few years and a 30-million-baht net profit for the latest full year.
Mono chief executive Sang Do Lee said his company's stock would attract more institutional investors after its SET listing, as some funds face restrictions on putting money into MAI-listed companies.
Institutional investors hold a combined 5% stake in Mono.
"The company hopes that the ratio of institutional investors who invest in our company will increase," Mr Lee said. "We are in talks with several fund managers and plan to arrange more roadshows to present information to institutional investors."
Mono aims for 3 billion baht in revenue this year, up from an estimated 1.6 billion in 2014.
The company has high hopes that a TV advertising rate increase to 25,000 baht a minute from 5,000 baht last year will drive revenue growth.
Better ratings would also help bolster the company's top line.
MONO shares closed yesterday on the MAI at 4.62 baht, up 22 satang, in trade worth 378 million baht.
APCO shares closed at 27.25 baht, down 25 satang, in trade worth 7 million baht.
