Business

Atom Corporation, founded in 1965 (incorporated in 1972), is a restaurant chain company that, as a member of the Colowide Group (voting rights ratio 41.2%), operates multiple formats—steak (Steak Miya), conveyor-belt sushi (Nigiri no Tokubei / Kaisen Atom), yakiniku (Karubi Taisho), tonkatsu, Japanese cuisine, Western cuisine, cafes, and others—mainly in regional, suburban, and roadside locations from Tohoku to Kansai. As of the end of FY2026 (ending March 2026), the company operated a total of 247 stores, comprising 237 directly-managed stores and 10 franchise stores. The Izakaya Business and Karaoke Business have been transferred to other companies within the group through company splits, and the company now focuses on the single segment of the Restaurant Business. It promotes community-based business operations centered on Fukui Prefecture, its founding location.

Business Model

The majority of net sales consists of store sales from food and beverage services provided at 237 directly-operated stores. Royalty income, based on fixed rates and fixed amounts, is earned from 10 franchised (FC) stores. The structure aims to enhance the earnings efficiency of existing assets through raw material procurement leveraging the Colowide Group's supply chain and business format conversions utilizing group synergies (e.g., franchising Ootoya Gohandokoro). With a cost of sales ratio of 37.9% and an SG&A expense ratio of 62.0% (FY2026 (ending March 2026)), the fixed cost burden is heavy, making improvements in utilization rates and average customer spending key to earnings improvement.

Company Strengths

The sushi format centered on 'Nigiri no Tokubei' and 'Kaisen Atom' has achieved two consecutive periods of year-on-year revenue growth, continuing to be the most stable growth driver within the Restaurant Business. By strengthening brand power through seasonal and regional-sourcing-focused fair promotions and menu composition reviews, the format has steadily enhanced its competitiveness.

The company possesses group synergies that enable it to transform its earnings structure while leveraging existing assets, such as converting underperforming 'Steak Miya' stores into 'Otoya Gohandokoro' outlets (two stores opened in February and March 2026) through an FC agreement with Otoya Holdings within the Colowide Group.

By operating multiple formats—steak, kaiten-zushi, yakiniku, tonkatsu, Japanese, Western, cafe, and others—across suburban and roadside locations in regional areas from Tohoku to Kansai, the company disperses dependence on any single format or region. It maintained 247 stores (237 directly operated, 10 FC) as of the end of FY2026 (ending March 2026), while also advancing the development of new formats such as 'Grillé Mia!' and 'Kamakura Kabuto'.

ENVALITH's Perspective

In FY2026 (ending March 2026), operating profit turned positive at ¥25 million, a swing from an operating loss of ¥670 million in the prior period. However, ordinary loss of ¥22 million and net loss of ¥1,507 million show that the bottom line remained deeply in the red. In addition to recording an impairment loss of ¥677 million, income tax adjustments of ¥608 million (reversal of deferred tax assets) pushed up the net loss. In the prior period, the company had recorded net income of ¥530 million due to the one-time factor of a gain on business transfer of ¥3,265 million, but the earnings power of its core business remains fragile, and structural profitability improvement has not yet been achieved.

Revenue was ¥30,408 million (down 14.3% year on year), representing a contraction of approximately 18% over five years. The main cause was the loss of revenue due to the divestiture of the Izakaya Business and Karaoke Business, but the Restaurant Business alone also continues to face external headwinds such as elevated raw material prices, rising labor costs, and strengthening consumer thrift. On the financial front, the acquisition of treasury shares for ¥2,127 million associated with the purchase of Class B preferred shares held by Colowide significantly compressed net assets, causing the equity ratio to decline from 38.5% in the prior period to 25.4%. Cash and cash equivalents also fell sharply from ¥6,703 million to ¥3,633 million, and the resulting decline in financial flexibility warrants close monitoring.

The earnings forecast for FY2027 (ending March 2027) projects revenue of ¥31,775 million (up 4.5% year on year) and operating profit of ¥930 million (up 3,578% year on year), representing a substantial anticipated improvement in profitability. The main assumptions underlying this forecast are an increase in average customer spending driven by the grand menu revision (new pricing theme) in April 2026, new store openings under the multi-format concept, and improved customer traffic resulting from renovations of existing stores. Externally, an improving trend in real wages and continued inbound demand supported by a weak yen could serve as tailwinds, but headwinds from elevated raw material and labor costs are also expected to persist. Achieving the projected operating margin of 3.0% will require both customer acceptance of the price revisions and control of selling, general and administrative expenses, and the feasibility of this outcome warrants further verification.

Growth Strategy

Rebuilding the profit base of the Restaurant Business through grand menu revisions, expansion of multi-format concepts, and utilization of group synergies

The grand menu was revised across all formats in April 2026, aiming to enhance experiential and informational value not merely through price revisions but also through product strengthening, service delivery review, and enhanced communication. The main expected effect is sales and profit improvement through higher average customer spending.

New stores combining "Grillé Mia!" with café functionality are being opened as a multi-format concept, aiming to maximize investment efficiency and improve store and staff utilization rates through flexible format configurations tailored to time of day and purpose of use. One store was opened in FY2026 (ending March 2026).

Steak Miya stores facing profitability challenges are being converted to the "Ootoya Gohandokoro" format as a franchisee of Ootoya Holdings, aiming to transform the profit structure by leveraging existing assets. Two stores, Tokai and Kitanagoya, were opened in February and March 2026.

13 stores were renovated in FY2026 (ending March 2026) (6 Steak Miya stores, 1 Nigiri no Tokubei store, 2 Kaisen Atom stores, 3 Karubi Taisho stores, 1 FC store). In FY2027 (ending March 2026), renovations covering both interior and exterior will continue to be implemented in a planned manner, aiming to achieve both improved customer traffic and profitability.

SG&A expenses in store operations and head office costs are being continuously controlled and optimized to build a profit base less susceptible to fluctuations in the external environment. SG&A expenses in FY2026 (ending March 2026) were significantly reduced to ¥18,846 million from ¥23,320 million in the previous fiscal year.
