Business

San-Ai Obbli Corporation is a comprehensive energy company founded in 1952. Its core business is the Petroleum-Related Business (approximately 84% of net sales), centered on the sale, storage, and shipping of petroleum products, followed by the Gas-Related Business handling LP gas and natural gas, an aviation fuel handling business centered around Haneda Airport, a chemical manufacturing and sales business, and Other Businesses including Clean Tech and construction work. The group, comprising 24 subsidiaries and 4 affiliated companies, recorded consolidated net sales of ¥611,570 million (FY2026, ending March 2026). Its major customers span petroleum distributors, large industrial consumers, airlines, and city gas consumers, and it operates a nationwide network of approximately 1,000 affiliated service stations along with refueling facilities at 7 domestic airports.

Business Model

While the company's revenue base rests on sales margins from petroleum, gas, and aviation fuel, it also generates multiple revenue streams, including storage and shipping fees entrusted by oil wholesalers and others, aviation fuel handling fees, city gas pipeline operation revenue, and real estate leasing income. In particular, the Aviation-Related Business has achieved high profit margins through unit price revisions of handling fees, characterizing a stable, infrastructure-holding revenue model. The company enhances financial efficiency through intra-group fund transfers via a Cash Management System (CMS).

Company Strengths

The company owns and leases refueling facilities at 7 domestic airports and operates an aviation fuel handling business centered on Haneda Airport. In FY2026 (ending March 2026), the combination of a revision to handling fee unit prices and an increase in international flight handling volume (up approximately 2% year on year) drove segment profit in the Aviation-Related Business up 55.7% year on year to ¥5,712 million. The profit margin as a share of revenue is exceptionally high, and the company holds infrastructure assets that competitors would find difficult to replicate in a short period.

Centered on Kygnus Sekiyu, the company operates a nationwide network of approximately 1,000 affiliated service stations, and runs businesses spanning petroleum retail, wholesale, industrial fuel oil, and lubricants. Revenue from the Petroleum-Related Business reached ¥516,413 million, accounting for approximately 84% of consolidated revenue, with the scale and diversity of its sales base serving as a source of competitive advantage.

In the LP gas business, the company has continued to expand its retail customer base through M&A, including the acquisition of business rights. In December 2025, it made Smart Solutions Co., Ltd. (the holding company of Kumamoto Sekiyu Co., Ltd.) a subsidiary, acquiring a customer base in the Kumamoto area. In the natural gas business, household sales volume increased following Imari Gas Co., Ltd.'s joining the group. Segment profit in the Gas-Related Business increased 8.7% year on year to ¥2,295 million.

ENVALITH's Perspective

The operating profit increase for FY2026 (ending March 2026) (up 4.6% year on year) was substantially driven by the Aviation-Related Business segment profit expanding 55.7% year on year to ¥5,712 million. In addition to structural earnings improvement from the fee unit price revision, an external factor—increased inbound foreign visitors leading to more international flight frequencies and new routes—pushed up handling volume by approximately 2% year on year. Whether the fee unit price revision proves permanent and future inbound demand trends will be key to performance. The forecast for FY2027 (ending March 2027) shows a conservative outlook with ordinary profit down 3.3% year on year, which may reflect an assumption that the effect of the unit price revision has run its course.

Segment profit in the Petroleum-Related Business deteriorated significantly to ¥5,670 million (down 23.1% year on year). Main causes were market instability from the government's fixed-amount reduction measures on fuel oil prices and the abolition of the provisional tax rates for gasoline tax and diesel tax, as well as deteriorating profitability in some transactions at Kygnus Sekiyu. As an external factor, bearish expectations for petroleum market conditions directly hit the wholesale segment. The question of how much the growth in the Aviation-Related Business and Other Businesses can offset the declining profitability of the petroleum and gas-related business, which accounts for over 84% of total revenue, is a focal point for assessing progress on Challenge 2030.

Operating cash flow for FY2026 (ending March 2026) surged to ¥23,114 million from ¥938 million in the prior period, but one of the main drivers was a one-time factor: the recovery of business guarantee deposits (¥6,109 million). Meanwhile, investing cash flow expanded year on year to an outflow of ¥5,236 million, centered on ¥6,477 million in acquisitions of property, plant and equipment. The increase in tangible and intangible fixed assets reached ¥10,818 million (versus ¥7,419 million in the prior period), indicating accelerating growth investment. The forecast for FY2027 (ending March 2027) projects net profit down 10.8% year on year to ¥8,200 million, a decline, with the dividend payout ratio at a high level of 75.5%. Room for further dividend increases appears limited, making the balance between investment and shareholder returns a key challenge.

Growth Strategy

Accelerating growth investment under Stage 2 of Challenge2030, promoting the transformation of the business portfolio away from dependence on petroleum

The company continues to make aggressive investments in refueling facilities centered on Haneda Airport (¥3,847 million in FY2026 (ending March 2026)), aiming to expand aviation fuel handling volumes and stabilize fee income. In FY2026 (ending March 2026), segment profit expanded 55.7% year on year to ¥5,712 million, as the effect of the revised fee unit price became apparent.

The company continues to promote the ongoing expansion of the number of customer households through M&A in the LP gas and natural gas businesses. In December 2025, it made Smart Solutions Co., Ltd. (holding company of Kumamoto Sekiyu Co., Ltd.) a subsidiary, entering the Kumamoto area. The company also achieved the group entry of Imari Gas Co., Ltd., and Gas-Related segment profit improved 8.7% year on year to ¥2,295 million.

Orders received in the Construction Business remained solid, and in FY2026 (ending March 2026), sales in Other Businesses increased 24.7% year on year to ¥7,166 million, with segment profit expanding 36.1% year on year to ¥1,176 million. In the Clean Tech Business, the recovery in demand for precision cleaning for semiconductor manufacturing equipment continues to be delayed, but the company continues to make capital investments aimed at expanding orders once the demand recovery phase begins.

The company continues to improve profit margins through supply chain optimization via more efficient purchasing and inventory management. Capital investment in FY2026 (ending March 2026) expanded to ¥656 million (approximately four times the previous fiscal year), strengthening the business foundation. Sales of proprietary Automotive-Related Products (car wash chemicals) exceeded the previous fiscal year in both sales volume and profit, and sales secured a 0.8% year-on-year increase to ¥12,775 million.
