• Optical device market share expected <50% in some markets
• Tablet product launch delays → backlight business drag in H1 FY2025

Increased debt following aggressive M&A and investment cycles has raised the company's financial risk profile. Total debt reached a five-year high in March 2025 and the total debt-to-capital ratio rose to 33.3% from 24.2% the prior year. Net interest-bearing debt was ¥241.4 billion at FY2025-end, with a target reduction to ¥200.0 billion by March 2026. Investing activities produced net cash outflows of ¥125.8 billion in FY2025 versus ¥76.3 billion in the prior year. Although the debt-to-equity ratio remained at a manageable 0.64, the rapid increase in borrowings to fund acquisitions has reduced the equity buffer and increases reliance on sustained operating cash flow to mitigate liquidity and refinancing risk.

Operational challenges in China's automotive and electronics markets have constrained regional growth. The Access Solutions segment experienced a slowdown in Chinese automotive demand, limiting net sales growth to 1.9% in FY2025. Reorganization costs for production sites and the exit from the camera actuator business in China added significant one-off expenditures. China accounted for 19% of consolidated net sales in FY2025, creating exposure to regional economic volatility and shifting domestic consumption patterns. Difficulties in securing rare earth materials for optical devices also contributed to sluggish performance in Q1 of the current fiscal year, necessitating ongoing restructuring that consumes management bandwidth and capital.

• Access Solutions China net sales growth: +1.9% in FY2025
• Sales from China: 19% of total net sales (FY2025)
• Resource constraints: rare earth procurement issues → Q1 slowdown

The 'Other' business segment persistently underperforms and produces recurring operating losses. This segment, comprising in‑house machine production and software development, saw net sales fall 21.7% to ¥3.5 billion in FY2025 and reported an operating loss of ¥1.2 billion, a deterioration of ¥466 million year-on-year. Management expects the operating loss to widen to ¥2.0 billion in FY2026, indicating continued drain on consolidated earnings. While these activities support internal operations, their lack of external commercial traction suggests misallocation of resources or the need for strategic pivoting to stop recurrent value erosion.
