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

Profit attributable to owners of parent for FY2026 (ending March 2026) reached ¥14,815 million (up 28.3% year on year), setting a new record high. ROE stood at 22.0% (16.5% in the prior period), achieving the medium-term management plan target, while ROIC also improved to 13.0% (from 11.3% in the prior period). The company implemented shareholder returns totaling ¥18,964 million, comprising ¥8,202 million in share buybacks and ¥10,762 million in dividends, while also progressing with capital optimization by reducing the equity ratio to 41% (from 43% in the prior period). However, for FY2027 (ending March 2026), the company has factored in an approximately ¥2.0 billion impact from raw material price increases stemming from the situation in the Middle East, projecting operating profit of ¥20,000 million (down 6.0% year on year), a decline in profit. The materialization of external environment risks will be the focal point of the assessment.

For FY2026 (ending March 2026), gross profit in the Electricity Business was ¥6,613 million (up 26.5% year on year), and the City Gas Business posted ¥19,966 million (up 1.9% year on year), continuing their growth, while gross profit in the LP Gas Business was ¥45,398 million (down 0.3% year on year), affected by margin compression from fluctuations in commercial-use raw material prices. The electricity set rate rose to 24.3% (from 23.5% at the prior fiscal year-end), leaving substantial room for further increases, and progress in revenue diversification through deeper cross-selling remains a point of continued attention. As fuel price trends directly affect margins in the Electricity Business and City Gas Business, monitoring raw material price trends remains essential as an external factor.

The consolidated earnings forecast for FY2027 (ending March 2026) projects a decline in profit, with operating profit of ¥20,000 million (down 6.0% year on year) and net profit of ¥14,000 million (down 5.5% year on year). The company estimates the impact of raw material price increases stemming from the situation in the Middle East at approximately ¥2.0 billion, explaining that absent this impact, operating profit would be ¥22.0 billion and net profit ¥15.4 billion. The LP Gas Business plans to stabilize procurement costs through the use of derivatives and other measures, but the scale and duration of the impact on earnings from a prolonged or expanded geopolitical risk remain unclear. Given the significant projected decline in operating profit for the cumulative first half of FY2027 (ending March 2026) to ¥3,400 million (down 32.0% year on year), the downside risk to earnings warrants careful assessment.

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.
