Bangkok Expressway and Metro Public Company LimitedToll hike on the Srirat-Wong Waen Outer Ring Expressway, where BEM recognizes 100% of toll revenue, adds an estimated 330-350 million baht per year.

Asia Plus Securities stated that the Royal Gazette has published a Ministry of Transport announcement adjusting toll rates for the Western Expressway, or the Srirat-Wong Waen Outer Ring Expressway in Bangkok, effective from December 15, 2026, under the concession contract's condition of adjusting tolls every 5 years. The project's concession runs until December 15, 2042. Under the new rates, vehicles with no more than 4 wheels rise from 65 baht to 80 baht per trip, vehicles with more than 4 but no more than 10 wheels rise from 105 baht to 130 baht, and vehicles with more than 10 wheels rise from 150 baht to 185 baht. This is the second increase under the new concession framework, which stipulates an increase of 15 baht each time every 5 years, starting from 2021. This toll adjustment is a positive factor for BEM, since the Srirat-Wong Waen Outer Ring Expressway is a route where BEM recognizes 100% of toll revenue, unlike inner-city expressways where it receives only a 40% revenue share. Although this route accounts for only about 5-6% of total expressway traffic volume, it generates roughly 14-15% of expressway business revenue. It is estimated to add about 330-350 million baht per year in revenue for the company. However, the research team views that BEM is entering a transition period toward a new round of growth, driven by the launch of the Orange Line electric train in 2028, which will directly add passengers to the Blue Line network. Meanwhile, opportunities from the Double Deck expressway project and the Purple Line South train operating contract remain important value-adding factors in the next phase. It therefore maintains a Buy recommendation with a DCF-based fair value of 8.20 baht.
