According to the Ministry of Transport, the number of passenger cars with 9 seats or less on expressways increased by about 27% in the second quarter compared with the same period in 2019.

Long-term benefits from: 1) relying on high-quality highways of the major shareholder Transportation Group, increase opportunities for injection of high-quality assets; 2) networking effect brought about by regional economic growth and continuous encryption of the provincial highway network; 3) long-term traffic flow and traffic income growth brought about by the reconstruction and expansion of core road production. To sum up, we estimate that the return net profit of the company from 2023 to 2025 is 1.64 billion yuan, respectively, corresponding to the 23-year PE of 10.4x and 1.7x. Compared with the historical five-year average, the current valuation still has upward space compared with the historical five-year average, and the dividend ratio is stable, the dividend ratio is attractive, and the "highly recommended" rating is given for the first time.

Risk hints: the regional economic growth is not as expected, the impact of some road property diversion under the road network planning is greater than expected, and the change of toll policy is greater than expected.
