On a quarterly basis, the second quarter (April–June) showed an acceleration in growth, with sales up 20.5% and operating profit up 42.2% compared to the first quarter (January–March).

2. Significant Upward Revision to Full-Year Guidance and Its Background

Following the strong performance in the first half, the company has revised its consolidated full-year earnings forecast for FY2026.

[Slide 4 Commentary: Revision of Full-Year Earnings Forecast]

The slide above is a critical document comparing the initial full-year plan for FY2026 with the revised forecast (announced in August) and the previous year's results. The revised plan projects net sales of 22,238 million yen (+27.4% YoY, +13.4% vs. initial forecast) , operating profit of 6,754 million yen (+46.1% YoY, +25.0% vs. initial forecast) , and an operating profit margin of 30.4% , significantly exceeding initial expectations.

The primary drivers for the revision are as follows:

• Lead Terminal Business : While the automotive market recovery remains gradual, it has stayed resilient, and sales of lead terminals for AI servers have surged . Price pass-throughs for rising material costs have also progressed.
• Optical Components & Devices Business : Orders have grown against the backdrop of active global investment in subsea cable projects . Contributions from new products and an improved product mix have also been significant.
• Exchange Rates : The full-year assumption has been adjusted from 1 USD = 150.00 JPY to 160.00 JPY (for the second half) . The exchange rate sensitivity (an impact of 80 million yen in annual sales and 30 million yen in operating profit per 1 yen fluctuation) has also acted as a tailwind.

3. Analysis of Profit Structure and Operating Profit Variance

A waterfall analysis of the operating profit variance for the first half (+1,137 million yen YoY) clarifies the growth drivers:

• Positive Factors : Increased sales volume contributed +1,580 million yen , and exchange rate effects contributed +567 million yen .
• Negative Factors : Higher cost of sales due to rising raw material prices ( -687 million yen ), increased labor costs ( -215 million yen ), higher expenses ( -267 million yen ), and increased personnel costs in SG&A ( -82 million yen ).

Real sales growth and favorable exchange rates have clearly outweighed the burden of rising costs, demonstrating the success of cost control measures and the shift toward high-value-added products.

4. Financial Position and Cash Flow Trends

Reflecting the strong performance, the company's cash-generating ability has improved dramatically.

• Assets : Total assets expanded from 28,319 million yen at the end of FY2025 to 31,213 million yen (+2,894 million yen) , primarily driven by a 2,487 million yen increase in cash and deposits to 10,905 million yen .
• Cash Flow : Operating cash flow surged from 803 million yen in the same period last year to 4,083 million yen . This was driven by higher pre-tax profit and a decrease in trade receivables (+1,261 million yen). With investment cash flow limited to -863 million yen, the company secured a substantial free cash flow of 3,220 million yen (compared to 461 million yen in the same period last year).

With a robust equity ratio (net assets of 25,489 million yen, equity ratio of approximately 81.7%), the company maintains a solid financial foundation for future capital investment and shareholder returns.

5. Segment Analysis ①: Lead Terminal Business Trends and AI Server Demand

The Lead Terminal business saw significant growth in the first half, with net sales of 5,360 million yen (+29.2% YoY) and operating profit of 549 million yen (+60.2% YoY) . Despite the delayed bottoming out of the consumer electronics and PC markets and the sluggish recovery in the European and Chinese automotive markets, demand for high-performance lead terminals for generative AI servers has been a strong driver.

[Slide 24 Commentary: AI Server Market Expansion and High-Reliability Lead Terminals]

The slide above explains the structure of "AI server demand," the most significant announcement for the mid-to-long-term growth of the lead terminal business. Because GPUs in AI servers consume massive amounts of power, small aluminum electrolytic capacitors with high voltage resistance, heat resistance, and low ESR (Equivalent Series Resistance) are essential for the multi-stage power conversion (AC to DC, DC to DC) from power supply units to GPU cores.

The company supplies high-value-added products such as high-conductivity terminals, burr-less products, and copper wire leads used in these high-performance capacitors. As the global generative AI market expands, the share of AI servers in the small aluminum electrolytic capacitor market is estimated to grow from 1.9% in 2025 to 8.9% by 2030 . In the company's sales mix, this segment rose to approximately 7% as of June 2026 (up sharply from about 3% in March 2026).

6. Product Value-Add and Maintaining Automotive Market Share

The business is not only seeing volume growth but also product mix improvement (higher value-add) .
