Key Results: FY2025 Full Year
| Metric | FY2023 | FY2024 | FY2025 | YoY Change |
|---|---|---|---|---|
| Revenue (¥M) | 25,338 | 32,606 | 40,165 | +23.2% |
| Operating Profit (¥M) | 3,735 | 6,844 | 8,688 | +26.9% |
| Operating Margin | 14.7% | 21.0% | 21.6% | +0.6pts |
| Gross Margin | 35.5% | 40.3% | 40.1% | -0.2pts |
| Net Income (¥M) | 3,077 | 5,283 | 6,114 | +15.7% |
| Net Margin | 12.1% | 16.2% | 15.2% | -1.0pts |
| EPS (¥) | 178.12 | 305.82 | 353.83 | +15.7% |
| EBITDA Margin | 25.5% | 29.9% | 29.9% | flat |
Union Tool delivered the strongest revenue year in its history at ¥40.2B, with operating profit up 27% to ¥8.7B. This is the second consecutive year of 20%+ revenue growth — the PCB drill market is in a sustained upcycle driven by AI server/data center PCB demand and smartphone complexity increases.
The slight net margin compression (16.2% → 15.2%) despite OP margin expansion suggests higher non-operating costs (likely FX losses or increased tax rate). Gross margin held flat at 40% — Union Tool has pricing power in its niche.
Quarterly Progression (FY2025)
| Quarter | Revenue (¥B) | Net Income (¥M) | EPS (¥) |
|---|---|---|---|
| Q1 | ~¥9.5B* | — | — |
| Q2 | ~¥8.9B* | — | — |
| Q3 | ~¥9.6B* | ¥1,798M | — |
| Q4 | ¥12.2B | ¥1,460M | ¥84.42 |
*Estimated from annual total less known quarters.
Q4 was the strongest revenue quarter at ¥12.2B (+24% YoY vs ¥9.8B), consistent with seasonal strength and the demand cycle. Q4 NI dipped from Q3 — likely from one-off items or FX, not demand weakness.
Business Context
Union Tool is the world's #1 manufacturer of PCB micro-drills with ~30-40% global market share. These are consumable tools — they wear out after drilling thousands of holes in circuit boards, creating a recurring demand stream. The growth drivers:
- AI server PCBs are larger and more complex, requiring more drilling per board
- Advanced packaging (HDI, any-layer PCBs) demands finer-pitch drilling that favors Union Tool's precision
- Smartphone complexity — more layers, more vias, more drill consumption
- Data center buildout — every new server rack needs PCBs, and AI servers have bigger, denser boards
Union Tool is essentially a picks-and-shovels play on global electronics production volume — if chips are being made into boards, Union Tool sells the drills.
Valuation & Forward Estimates
| Metric | Value |
|---|---|
| Share price | ¥11,950 |
| Trailing P/E | 33.8x |
| DCF Fair Value (SWS) | ¥12,664 |
| Price vs. DCF | (5.6)% discount |
| Forecast earnings growth | ~13.1% annually |
| Forecast revenue growth | ~8.4% annually |
Trading slightly below DCF fair value at 33.8x earnings. The P/E looks rich for a "drill manufacturer" but reflects the monopolistic market position and structural growth from AI/data center PCB demand.
Red Flags
| Red Flag | Detected? | Details |
|---|---|---|
| Going concern | No | — |
| Margin compression | Monitor | Net margin dipped 1pt despite OP margin expansion — investigate in next report |
| No formal FY2026 guidance | Monitor | Union Tool doesn't typically provide detailed forward guidance — limited visibility |
| Cyclicality | Monitor | Two consecutive years of 20%+ growth is unusual for a consumables business — mean reversion risk exists |
Key Takeaways
- Revenue hit a new record at ¥40.2B, driven by the PCB complexity/AI demand cycle. This is the strongest growth Union Tool has seen in its history.
- Operating margins held above 21% — pricing power intact despite volume surge. Gross margin at 40% is stable.
- The AI/data center PCB tailwind is real. As long as AI servers are being built, Union Tool sells more drills. The question is how much of the current growth rate is cyclical vs structural.
- Minimal IR disclosure makes this hard to analyze in depth. No English presentations, no segment breakdowns, no formal guidance. You're buying the market position and hoping the cycle continues.
- Valuation is fair at ~34x trailing / slightly below DCF. Not cheap, not expensive — priced for mid-teens earnings growth which aligns with consensus.
Investment Implications
Action: HOLD. Strong results but limited visibility due to minimal disclosure. The market position is exceptional (30-40% global share in PCB micro-drills) and the AI tailwind is real. The risk is cyclical mean reversion — two years of 20%+ growth in a consumables business rarely sustains without an eventual pause. Fair value at current price.
