• Shibaura Machine published its earnings presentation for the fiscal year ending March 2026 on June 2, 2026.
• For FY2025, actual net sales were ¥132.8 billion, a shortfall of ¥7.2 billion compared to the forecast of ¥140.0 billion. Operating profit was ¥4.3 billion, ¥0.7 billion below the forecast of ¥5.0 billion.
• Ordinary profit met the forecast at ¥5.0 billion, but net profit attributable to owners of parent was ¥1.0 billion, a shortfall of ¥2.3 billion against the forecast of ¥3.3 billion.
• The miss in net profit was primarily due to special losses, including impairment loss on goodwill of SHIBAURA MACHINE LWB GmbH and special retirement benefits.
• Total orders received were ¥119.1 billion, ¥18.9 billion below the forecast of ¥138.0 billion. However, orders for large machine tools and ultra-precision machine tools increased. Orders for the “BSF” (separator film manufacturing equipment for lithium-ion batteries) for extrusion molding machines included a full line for the first time in approximately two years, though this segment did not meet its initial plan.

• Kanematsu Co. released the summary of the Q&A from its FY2026/3 full-year earnings briefing on June 2, 2026, which was held on May 18, 2026.
• The net profit for FY2026/3 landed at 32.5 billion yen (estimated underlying profit of approximately 33.0 billion yen), exceeding expectations, with all segments performing well towards the fiscal year-end.
• Of the 60.0 billion yen growth investment planned under the Mid-Term Management Plan (MTP), the actual execution for ICT-related investments is currently 2.0 billion yen against a target of 40.0 billion yen.
• The delay in large-scale ICT-related investments is attributed to factors such as target company valuations not aligning with Kanematsu’s expectations or target companies declining offers.
• Kanematsu plans to continue considering large-scale ICT investments, stating a willingness to exceed the initial 40.0 billion yen framework if suitable, high-quality projects emerge.
• No additional shareholder returns are planned for the current MTP period; however, they may be considered in the next MTP, balancing growth investment execution.

The Q&A summary highlights Kanematsu’s stronger-than-expected underlying profit, driven by robust performance across all segments. Investors may note the significant gap between planned and executed ICT-related growth investments, yet management’s flexible approach to exceeding the initial investment framework for opportune deals could signal future growth potential. The decision to prioritize growth investments over additional shareholder returns during the current MTP period suggests a focus on long-term expansion.

• Pietro Co., Ltd. announced a partial correction to its “Financial Results for the Fiscal Year Ending March 31, 2026 (Consolidated, Japanese GAAP),” originally published on May 15, 2026.
• The reason for the correction is that certain matters requiring amendment in the descriptions were identified after the submission.

• It is explicitly stated that this correction has no impact on the company’s business performance.
• Numerical data (XBRL) was also corrected, and the revised XBRL data will be transmitted.

Corrections to financial statements by listed companies are critical for investors to ensure information accuracy. This correction from Pietro is specified as a revision to descriptive content with no impact on business performance, which may suggest that it does not indicate a fundamental change in financial position or operational outlook. The accompanying XBRL data correction means data users should ensure they are referencing the updated version.

• Daisan Co., Ltd. announced its consolidated financial results for the fiscal year ended April 2026 (April 21, 2025, to April 20, 2026).
• Consolidated results show net sales of ¥11,139 million (up 2.8% year-on-year), operating profit of ¥268 million (down 27.5% year-on-year), ordinary profit of ¥290 million (down 15.9% year-on-year), and profit attributable to owners of parent of ¥262 million (down 21.8% year-on-year).
• By segment, the construction services business reported sales of ¥7,669 million (up 6.0% year-on-year), and the manufactured goods sales business reported sales of ¥1,009 million (down 14.5% year-on-year).
• The annual dividend for the fiscal year ended April 2026 was ¥22.00 per share (¥11.00 for year-end), a decrease from ¥24.00 in the previous fiscal year.
• For the full fiscal year ending April 2027, the company forecasts consolidated net sales of ¥12,000 million (up 7.7% year-on-year), ordinary profit of ¥220 million (down 24.4% year-on-year), and profit attributable to owners of parent of ¥130 million (down 50.4% year-on-year).

Daisan’s FY2026 results show a divergence between revenue growth and declining profits across key metrics. This appears to be influenced by increased personnel costs in the construction services business, anticipating future order expansion, and reduced demand in the manufactured goods sales business due to market cautiousness and a reactionary decline following regulatory changes. The forecast for FY2027 indicates continued sales growth but further anticipated profit declines, which may prompt investors to closely monitor the company’s business structure and cost management strategies.

• Infroneer Holdings’ subsidiary, Sumitomo Mitsui Construction Co., Ltd., completed the full acquisition of Mitsui Sumitomo Kensetsu Road Co., Ltd. on June 2, 2026.
• Sumitomo Mitsui Construction had acquired 8,848,998 shares of Mitsui Sumitomo Kensetsu Road (representing 95.38% of voting rights) as of April 28, 2026, through a tender offer initiated on March 10, 2026.
• Following the tender offer, Sumitomo Mitsui Construction decided on May 8, 2026, to request the sale of all shares from minority shareholders of Mitsui Sumitomo Kensetsu Road under Article 179, Paragraph 1 of the Companies Act, acquiring all such shares on the acquisition date.
• Consequently, Mitsui Sumitomo Kensetsu Road has become a wholly-owned subsidiary of Sumitomo Mitsui Construction.

This announcement confirms the scheduled completion of a full subsidiary acquisition within the Infroneer Holdings Group, representing a step in internal business restructuring. The full integration of Sumitomo Mitsui Construction and Mitsui Sumitomo Kensetsu Road could facilitate optimized resource allocation and investment across the group, potentially enhancing corporate value. The realization of synergies within the group’s future strategies will be worth monitoring.

• E-Guardian published a Q&A on June 2, 2026, regarding its Q2 FY2026 financial results and the complete acquisition of Outsourcing Communications Co., Ltd.
• The Q&A addresses expectations for large projects in the second half of the fiscal year, including additional orders from existing clients and new client acquisitions in monitoring and screening operations.
• The improvement in gross profit margin is attributed to the full-scale implementation of AI, establishing an “AI-human collaboration model (AI-BPO)” that structurally elevates profitability.
• The closure of the Tachikawa and Koriyama centers is viewed as a positive outcome of AI strategy-driven efficiency, transitioning to a new structure where personnel and facility growth are not necessarily proportional to revenue growth.
• The full acquisition of Outsourcing Communications is positioned as the first step into new BPO domains, aiming to apply the “AI-BPO” model to the acquired company for a high-profit business model.
• E-Guardian plans to pursue multiple M&A deals during the current and next fiscal year, with investment sizes ranging from several hundred million to several billion yen, depending on the nature of the deals.

The released Q&A suggests that E-Guardian’s AI strategy is yielding tangible results, such as improved profit margins and operational efficiency. The establishment of the “AI-BPO” model, potentially leading to a shift away from labor-intensive business, could be a critical factor for understanding future business structure changes. Furthermore, the company’s clear strategy to integrate M&A with its AI initiatives to expand into new BPO areas and enhance profitability is worth monitoring.

• G-Geniee Co., Ltd. resolved at its Board of Directors meeting on June 2, 2026, to absorb and merge its consolidated subsidiary, CATS Inc.

This absorption merger is stated to consolidate management resources, streamline operations, and accelerate decision-making. It suggests an aim to further strengthen existing business synergies, such as product collaboration and customer base utilization, through organizational integration. While the direct impact on consolidated performance is expected to be limited due to CATS being a 100% subsidiary, this move could be seen as part of a broader management strategy to enhance corporate value.

• Consequently, the description of “cash flows from operating activities” was corrected from “8,925 million yen income” to “8,372 million yen income.”

The adjustment to operating cash flow may also impact the perception of the company’s cash-generating capabilities.
