| Metric | Current Period | Same Period of Previous Year | YoY |
|---|---|---|---|
| Revenue | ¥111.2B | ¥100.3B | +11.0% |
| Operating Income | ¥14.6B | ¥5.8B | +149.1% |
| Ordinary Income | ¥15.8B | ¥8.0B | +97.2% |
| Net Income | ¥11.9B | ¥8.6B | +38.8% |
| ROE | 1.8% | 1.3% | - |
In FY2027 Q1, Revenue increased and Operating Income expanded significantly to 2.5x the previous-year level, resulting in a substantial improvement in profitability. Revenue was ¥111.2B (+11.0% YoY), Operating Income was ¥14.6B (+149.1%), Ordinary Income was ¥15.8B (+97.2%), and Net Income was ¥11.9B (+38.8%; Net Income attributable to owners of the parent was ¥11.76B, +40.3%). The gross profit margin was 34.1% (an improvement of approximately +560bp YoY), while restrained SG&A expenses supported a significant expansion in the Operating Income margin to 13.1%, versus 5.8% in the previous year.
【Revenue】Revenue increased 11.0% YoY to ¥111.2B. As the Company operates in a single segment—manufacturing and sales of diamond tools—expanding demand, pricing, and an improved product mix appear to have driven the overall increase in Revenue.
【Profit and Loss】Against Cost of Sales of ¥73.3B (cost ratio: 65.9%), SG&A expenses increased only approximately +2.8% YoY to ¥23.4B. The increase in expenses remained below the rate of Revenue growth, generating operating leverage. In non-operating items, non-operating income of ¥1.6B, including a foreign exchange gain of ¥0.9B, lifted Ordinary Income to ¥15.8B (+97.2%). Extraordinary losses consisted solely of an impairment loss of ¥0.1B, resulting in a limited impact on Net Income. Net Income attributable to owners of the parent was ¥11.76B (+40.3%). Although the results represent increases in both Revenue and profit, with core margin improvement as the primary factor, they also include a certain contribution from foreign exchange gains in non-operating income.
The Group operates a single segment consisting of the manufacture and sale of diamond tools and related operations; therefore, performance by segment is not disclosed.
【Profitability】The Operating Income margin improved significantly to 13.1% from 5.8% in the previous year, an improvement of approximately +727bp, while the Net Income margin rose to 10.6% from 8.6%. The improvement began with the gross profit margin, which increased to 34.1% from approximately 28.5% in the previous year.【Cash Quality】Cash and deposits were ¥150.1B, a decrease of ¥10.7B YoY, while accounts receivable were ¥113.1B (+5.1%) and inventories were ¥37.2B, indicating an increase in working capital and the possibility of a time lag in cash conversion relative to profit growth.【Investment Efficiency】ROE was 1.8%, and the total asset turnover ratio remained low. Abundant assets, including investment securities of ¥157.0B and cash of ¥150.1B, are weighing on asset turnover.【Financial Soundness】The Equity Ratio was extremely high at 81.2%. Cash of ¥150.1B substantially exceeded long-term borrowings of ¥45.0B, indicating a conservative and robust financial foundation.
Although detailed disclosure of the cash flow statement is not available, an analysis of funding trends based on changes in the balance sheet indicates that cash and deposits decreased by ¥10.7B to ¥150.1B from ¥160.8B in the previous year, while accounts receivable increased by ¥5.5B and inventories remained approximately flat. Investment securities increased by ¥24.5B, suggesting that additional investments, in addition to valuation gains, absorbed a portion of cash. Net assets increased by ¥17.6B through the accumulation of Net Income and comprehensive income. While the pace of increase in accounts receivable was close to Revenue growth (+11.0%), accounts payable remained flat. Accordingly, there is limited room for expansion of supplier credit, and improvements in working capital efficiency will determine the Company’s future cash-generation capacity.
Extraordinary losses for the current period consisted solely of an impairment loss of ¥0.1B, equivalent to 0.9% of Net Income, indicating that the impact of temporary factors was limited. Non-operating income of ¥1.6B included a foreign exchange gain of ¥0.9B, equivalent to approximately 6% of Operating Income of ¥14.6B, meaning that Ordinary Income included a certain non-recurring contribution. The effective tax rate, calculated by deducting corporate income taxes and other taxes of ¥3.7B from Profit Before Tax of ¥15.6B, was approximately 23.7%, a reasonable level. No significant divergence was observed in the bridge from Ordinary Income to Net Income. Comprehensive income was ¥25.7B, substantially exceeding Net Income of ¥11.9B. This difference was primarily attributable to a ¥19.1B improvement in valuation difference on securities, which is separate from core business earnings and therefore warrants attention.
Progress toward the full-year plan—Revenue of ¥455.0B, Operating Income of ¥50.0B, Ordinary Income of ¥53.0B, and Net Income of ¥37.0B—was 24.5% for Revenue, 29.1% for Operating Income, 29.7% for Ordinary Income, and 31.8% for Net Income in Q1. Profit progress is therefore ahead of Revenue progress. The background includes gross margin improvement, expense restraint, and the contribution from foreign exchange gains. If the upside in core margins can be maintained, progress toward achieving the plan can be considered favorable. Although the earnings forecast was revised during the quarter, the dividend forecast was not revised.
Based on the Company’s plan, the annual dividend is ¥34, increased from the previous year’s actual dividend of ¥15. The Payout Ratio against assumed EPS of ¥76.87 is approximately 44.2%. Supported by a strong financial foundation, including cash of ¥150.1B and an Equity Ratio of 81.2%, the Company has substantial capacity to maintain and continue its dividend.
Working Capital Accumulation Risk: Accounts receivable were ¥113.1B (+5.1% YoY), while inventories were ¥37.2B, indicating delays in cash collection and inventory turnover relative to Revenue growth. This may delay the conversion of Operating Income into cash.
Foreign Exchange Risk: A foreign exchange gain of ¥0.9B lifted Ordinary Income during the current period. This contribution was equivalent to approximately 6% of Operating Income of ¥14.6B and could become a factor weighing on profit if exchange rates reverse.
Securities Price Fluctuation Risk: Investment securities reached ¥157.0B (+18.5% YoY), and changes in market value may affect comprehensive income and Net Assets (AOCI ¥9.97B).
Profitability and Returns

| Net Income Margin | 10.7% | 7.0% (3.2%–10.6%) | +3.7pt |
Both the Company’s Operating Income margin and Net Income margin exceed the industry median, placing its profitability in the upper tier of the industry.
Growth and Capital Efficiency
| Metric | Company | Median (IQR) | Delta |
|---|---|---|---|
| Revenue Growth Rate (YoY) | 11.0% | 6.2% (-1.1%–14.6%) | +4.8pt |
The Revenue growth rate also exceeds the industry median, although it has not reached the upper limit of the IQR (14.6%), placing the Company’s growth in the upper group within the industry.

The sharp improvement in the Operating Income margin from 5.8% in the previous year to 13.1%, reflecting positive operating leverage from pricing, mix improvement, and expense restraint, is noteworthy as a qualitative change in the earnings structure.
Full-year progress was 29.1% for Operating Income and 31.8% for Net Income, exceeding Revenue progress of 24.5%. Profit progress is therefore ahead of schedule, although the results include non-recurring factors such as foreign exchange gains.
While financial soundness is extremely high, as indicated by an Equity Ratio of 81.2% and low Debt levels, ROE remains low at 1.8%. Working capital efficiency, affected by increases in accounts receivable and inventories, is a structural factor that will determine future cash-generation capacity.
