Business
Nippon Gas Co., Ltd. is a comprehensive energy company founded in 1955 and listed on the Prime Market of the Tokyo Stock Exchange. Centered on its LP Gas Business (1,051 thousand customers, the largest operator in the Kanto region), the company operates three businesses: LP gas, electricity retail (404 thousand customers), and city gas (609 thousand customers). Its main customers are residential and commercial demand-side users, with a supply network built primarily around the Kanto region. The group consists of 13 subsidiaries and 1 affiliated company, and it possesses a vertically integrated value chain spanning gas and electricity sales as well as equipment sales, installation, platform provision, and transportation. In 2021, the company completed "Yume no Kizuna Kawasaki," one of the world's largest LP gas hub filling stations, strengthening its infrastructure base.
Business Model
The company maximizes per-customer revenue by bundling multiple energy sources—LP gas, city gas, and electricity. The electricity bundling rate rose to 24.3% at the end of FY2026 (ending March 2026). The Equipment, Installation, and Platform businesses also function as additional revenue sources, with gross profit from Equipment, Installation, and Platform sales reaching ¥4,769 million in FY2026 (ending March 2026), up 14.0% year on year. While expanding the customer base through industry consolidation via M&A, the company also aims to curb churn and deepen revenue through security/safety outsourcing services and housing-related services, among others.
Company Strengths
The number of LP gas customers as of the end of FY2026 (ending March 2026) was 1,051 thousand (up 21 thousand from the previous fiscal year-end), continuing monthly net increases. The company holds a 16% share within its operating area, and by focusing on detached houses and family-oriented apartment complexes, it has been building up a base of long-term contract customers. This customer base serves as the starting point for cross-selling electricity and city gas as well as equipment sales, supporting compound revenue growth.
The company has built a proprietary logistics and filling infrastructure, deploying multiple depot stations across the Kanto region centered on the "Yume no Kizuna Kawasaki" facility completed in 2021. Combined with ICT infrastructure such as automatic meter-reading systems and delivery optimization, it achieves operational efficiency exceeding the industry average. This infrastructure functions as an entry barrier that competitors cannot easily replicate in a short period of time.
In FY2026 (ending March 2026), the company took over LP gas customers from the largest number of companies since data collection began, and also achieved new consolidations such as Tokyo Energy Alliance. Backed by long-term relationship building, the company has established a mechanism for continuously absorbing customers handed over from exiting operators. With high capital efficiency—ROE of 22% and ROIC of 13%—as its weapon, it possesses the financial foundation to lead industry consolidation.
ENVALITH's Perspective
Performance Trend
Net sales grew 28% over five fiscal periods, from ¥162,552 million (FY2022, ending March 2022) to ¥208,480 million (FY2026, ending March 2026). Operating profit increased 66% from ¥12,786 million (FY2022) to ¥21,278 million (FY2026), with FY2026 marking a record high, up 14.7% year on year. The factors behind the profit increase in FY2026 included an expansion in gross profit in the Electricity Business (+¥1,386 million), growth in the equipment installation platform business (+¥585 million), and a ¥538 million decrease in SG&A expenses. As external factors, trends in fuel prices affected margins in the Electricity Business and City Gas Business, while an increase in the valuation of held securities also contributed to the financial position. For FY2027 (ending March 2027), the company has factored in a surge in raw material prices stemming from Middle East tensions (impact of approximately ¥2.0 billion), forecasting operating profit of ¥20,000 million (down 6.0% year on year), its first projected profit decline, indicating that external environmental risks have materialized.
Growth Strategy
Aiming to maintain a high ROE level through evolution into a comprehensive energy business, industry consolidation, and capital optimization
By focusing on detached houses and family-oriented multi-unit dwellings, the company achieved continuous monthly net increases, reaching 1,051 thousand contracts at the end of FY2026 (ending March 2026). It recorded the highest number of M&A transactions since data collection began, newly consolidating Tokyo Energy Alliance and others. From FY2027 (ending March 2027) onward, the company plans to continue promoting industry consolidation, including taking over customers from withdrawing operators.
The electricity set rate was raised to 24.3% at the end of FY2026 (ending March 2026) (from 23.5% at the end of the previous fiscal year), and the number of electricity customers expanded to 404 thousand contracts (up 24 thousand contracts from the previous fiscal year-end). Backed by a pricing design not linked to the wholesale electricity market and secured stable power sources, the company will continue to actively expand its business scale, including taking over customers from withdrawing operators.
Sales volume of hybrid water heaters increased 36% year on year, and gross profit in the Equipment, Installation & Platform business expanded to ¥4,769 million (up 14.0% year on year). From FY2027 (ending March 2027) onward, the company aims to expand housing-related services such as high-pressure drain cleaning, air conditioner cleaning, and house cleaning, with the goal of extending contract duration and increasing revenue per customer.
Under the medium-term management plan for FY2024 (ending March 2024) through FY2026 (ending March 2026), the equity ratio was reduced from 48% (end of FY2023, ending March 2023) to 41% (end of FY2026, ending March 2026), achieving the target ROE of 22.0%. In FY2026 (ending March 2026), the company returned a total of ¥18,964 million to shareholders, comprising ¥8,202 million in share buybacks and ¥10,762 million in dividends. The annual dividend forecast for FY2027 (ending March 2027) is ¥110 (up from ¥103 in the previous fiscal year), maintaining a policy of increasing dividends. As a subsequent event, the cancellation of 4,875,400 treasury shares (4.3% of total shares issued) is scheduled for May 14, 2026.
By using AI/IoT to control hybrid water heaters, storage batteries, solar panels, and other devices that combine electricity and gas, the company aims to reduce peak electricity demand and contribute to the stabilization of the power grid. By realizing the added value of proposing optimal energy usage, the company seeks to establish its position as an infrastructure operator responding to the instability of regional energy supply and demand.
