Commercial Paper: a-1, Affirmed

RATIONALE: Saibu Gas Co., Ltd. serves major cities of the northern Kyushu region, such as , Kitakyushu, , , and . The company is ranked after the three leading players in the industry, with about 1.1 million customer households. Its strength lies in the fact that lucrative residential gas accounts for a large proportion of total sales. Meanwhile, it has difficulty raising sales and transmission efficiency because supply areas are geographically dispersed. Since the full liberalization of the retail city gas market, customers, especially in the residential gas segment, have continued to migrate to services provided by other operators, which is partly due to aggressive marketing efforts by Kyushu Electric Power Co., Inc. Saibu Gas intends to avoid a war of attrition resulting from price competition and retain its customers by, for example, providing gas equipment inspection service for free. In the industrial gas segment, on the other hand, potential demand for fuel conversion is large. Wholesale supply of city gas also keeps increasing. In the retail electricity business, which the company entered in FY2016 (the year ended March 2017), the number of supply contracts is steadily growing. Its operating base centered on the city gas business is unlikely to be undermined. That said, the business environment is becoming challenging, as gas demand from major customers, particularly from industrial customers, is expected to decrease amid the spread of the novel coronavirus. Close eyes will be on future developments. Owing to a series of large investment projects, including the construction of the Hibiki LNG terminal in Kitakyushu City and the northern Kyushu pipeline, Saibu Gas is heavily indebted and its financial base is below the level required for the rating. To effectively utilize the Hibiki LNG terminal, it is now in discussions with a Russian enterprise, aiming to establish a joint venture that sells liquefied natural gas in Asia. R&I will pay attention to the progress of the discussions, focusing on whether or not this pushes Saibu Gas into excessive risk-taking. The company is working to expand businesses other than the city gas business, such as real estate. Its group mid-term management plan formulated in 2019, "Scrum 2022", calls for raising the proportion of the real estate business to approximately 20% in the business portfolio by FY2022. Saibu Gas plans to invest up to 50 billion yen in growth areas including real estate. R&I will closely examine the profitability of such businesses and the extent of the financial burden for the investment. In April 2021, Saibu Gas will separate the group's management and business functions and transition to a holding company structure centered on Saibu Gas Holdings Co., Ltd. (tentative name). R&I will observe developments during the transition period, focusing mainly on how to transfer liabilities and the holding company's double leverage ratio, and incorporate them into the rating.
