Business
Achilles Corporation is a plastics processing manufacturer founded in 1947, listed on the Prime Market of the Tokyo Stock Exchange. With 19 consolidated subsidiaries and 3 affiliated companies, the company reported net sales of ¥81,802 million (FY2026, ending March 2026). Its business is organized into three segments: the "First Business Division" (Film, Vehicle Materials, Urethane, Industrial Materials), the "Second Business Division" (Insulation Materials, Building & Interior Materials, Disaster Prevention Products), and "Shoes BU" (Shunsoku, Achilles Sorbo, BROOKS, and others). Major customers span a wide range of industries including automotive, semiconductors, medical devices, construction, and retail, and the company operates globally with overseas bases in the US, China, and Taiwan in addition to its domestic plants. Under its medium-term management plan (FY25–FY27), the company has set "Global Solution Provider" as its long-term goal, promoting selection and concentration in priority fields such as electronics, mobility, and medical.
Business Model
Centered on proprietary plastics processing technologies—compounding, film formation, foaming, insulation, and conductivity treatment—the company manufactures and sells a diverse range of products including vehicle interior materials, medical films, semiconductor transport components, insulation materials, and shoes. The First Business Division (Electronics, Medical, Mobility) accounts for approximately 61% of revenue, the Second Business Division (Building Materials, Disaster Prevention) approximately 28%, and the Shoes BU approximately 11%. The structure aims to improve profit margins through cost reduction via consolidated manufacturing at production sites and a product mix shift toward high-value-added fields.
Company Strengths
The company possesses proprietary plastic processing technologies such as film forming, foaming, and conductivity treatment, and develops high-value-added products including semiconductor wafer transport components, RIM-molded products for medical devices, and Film (for Medical & Electronics Applications). In FY2026 (ending March 2026), the First Business Division's segment profit increased 228.0% year-on-year to ¥3,287 million, demonstrating that technological capability translates directly into profitability.
In addition to multiple domestic plants (Ashikaga, Shiga, Bibai, Kyushu, etc.), the company has overseas bases in the United States, China (Shanghai, Foshan, Kunshan), and Taiwan. In FY2026 (ending March 2026), U.S. sales expanded from ¥8,018 million in the previous fiscal year to ¥10,390 million, with the global production and sales structure supporting growth in the North and Central American markets.
The "Shunsoku" brand held by the Shoes BU has surpassed cumulative series sales of 86 million pairs, giving it high brand recognition and strength in the domestic children's footwear market. The company also operates multiple other brands such as "Achilles Sorbo" and "BROOKS," giving it the capability to address the health-conscious market as well. Note that this segment faces structural headwinds such as the declining birthrate and weak department store sales, making the maintenance of brand strength a challenge.
ENVALITH's Perspective
Performance Trend
Sales trended sideways, moving from ¥75,953 million in FY2022 to ¥82,917 million in FY2023, ¥78,607 million in FY2024, ¥79,093 million in FY2025, and ¥81,802 million in FY2026 (ending March 2026). Operating profit had been in the red for three consecutive years from FY2023, but the company achieved a return to profitability in FY2026 (ending March 2026) with operating profit of ¥2,972 million. The main drivers were an increase in gross profit (from ¥14,484 million to ¥17,692 million) owing to substantial growth in film for medical applications and expanded sales of industrial materials, as well as cost reductions from consolidating manufacturing sites. As an external factor, foreign exchange gains of ¥693 million from the continued weakening of the yen also boosted ordinary profit (¥3,919 million). For FY2027 (ending March 2027), operating profit is forecast to decline to ¥2,200 million (down 26.0% year on year) due to increased investment in human capital and DX as well as the fading of foreign exchange gains.
Growth Strategy
Under the medium-term management plan for FY25–FY27, the company is pursuing three pillars: "selection and concentration," "new value creation," and "global strategy."
The company has positioned medical-use film and semiconductor-related industrial materials as top-priority fields, promoting expanded manufacturing capacity and deeper customer engagement. In FY2026 (ending March 2026), First Business Division segment profit expanded to ¥3,287 million (up 228.0% year on year), and continued growth is expected in FY2027 (ending March 2027) as well.
The company has positioned regional profitability management as a key management indicator, expanding U.S. sales in the First Business Division by 29.6% from ¥8,018 million in the prior period to ¥10,390 million in the current period. Business expansion in priority fields continues to be promoted, with a focus on the North/Central America region.
Active investment in human capital management and DX promotion, as set forth in the medium-term management plan, has already been incorporated into the FY2027 (ending March 2027) earnings forecast. This is one of the main factors behind the projected decline in operating profit for FY2027 (down 26.0% year on year), with the aim of improving productivity and competitiveness over the medium to long term.
Amid external headwinds such as the declining birthrate and sluggish consumer spending, the company improved segment loss by ¥651 million, from ¥972 million in the prior period to ¥321 million, through review of procurement costs, expense reductions, and price revisions. The company continues to aim for further loss reduction through ongoing cost-cutting activities and the introduction of new functional products.
The disaster prevention business has recorded impairment losses for two consecutive periods (¥3,256 million in FY2025 and ¥905 million in FY2026), highlighting delays in achieving profitability. While overall profit in the Second Business Division has improved due to price revisions in Insulation Materials and Building & Interior Materials and expansion into the non-residential field, a fundamental review of the direction of the disaster prevention business remains a challenge.
