Kulicke and Soffa Industries, Inc. (KLIC) | The Buildout — AI Infrastructure
The Verdict
Kulicke and Soffa supplies the tools that assemble chips after wafer fabrication: wire bonders and consumables, plus a growing advanced-packaging line built around fluxless thermo-compression bonding. The AI infrastructure buildout reaches KLIC through customer spending on packaging capacity — both the wire-bonded chips used across data-center infrastructure and the advanced-packaging tools used for heterogeneous integration.

What We Like
- Management says data centers rely on wire bonding at least as much as, if not more than, smartphones and PCs, making the core ball-bonding franchise a direct AI-infrastructure beneficiary.
- Ball Bonding Equipment produced $97.6 million of H1 FY2026 operating income on $270.5 million of revenue, more than doubling revenue year over year.
- Singapore TCB capacity expansion targets approximately $400 million of revenue support by the first half of fiscal 2027, with only $20 million of total capex.
- China utilization is over 95%, while memory and general semiconductor are around 90%; purchase orders are extending abnormally far into Q2.
- Balance sheet at April 4, 2026 held $487.9 million in cash, cash equivalents, and short-term investments against $39.8 million in total debt.
What We’re Watching
- Top three customers were 39.4% of H1 FY2026 revenue; top two were 50.0% of accounts receivable.
- Gross margin fell from 49.5% in Q2 to 47.8% in Q3, with Q4 guided at 48%, below the earlier 49–50% commentary.
- Non-GAAP OpEx rose from $73.8 million in Q2 to $82.6 million in Q3, with about $87.5 million guided for Q4; management calls the increase temporary.
- Advanced Solutions still lost $16.6 million in H1, with R&D of $29.4 million; HBM remains only in qualification.
The near-term thesis is strengthening: management beat the Q3 revenue guide, raised Q4 above its earlier 5–10% comment, and committed to new TCB capacity. But the earnings conversion is less clean. The open question is whether the mix shift to lower-margin customers and rising operating expenses are temporary or whether revenue growth outruns profitability into FY2027.
Earnings Beat
Kulicke and Soffa reported June-quarter revenue of $330.4 million, up 36.2% sequentially and 123% year over year. Gross margin was 47.8%. GAAP net income was $57.4 million, or $1.07 per diluted share; non-GAAP net income was $64.2 million, or $1.20 per share.
| Metric | Q2 FY2026 | Q1 FY2026 | Q2 FY2025 | YoY |
|---|---|---|---|---|
| Revenue | $243M | $200M | $162M | +49.8% |
| Gross margin | 49.5% | 49.4% | 24.9% | +2460bps |

Demand continues to improve at a faster pace than previously expected, and our operational teams are aggressively ramping production to support customer capacity and technology requirements.— Lester Wong, Interim Chief Executive Officer and Chief Financial Officer, August 6, 2026 earnings call
Management tone: Management's tone remained confident and operationally focused. Wong answered questions directly, supplied the first verbal FY2027 TCB range, declined to endorse a $450 million quarterly run rate, and acknowledged that visibility is usually short.
Management Guidance
For Q4 FY2026, management guided revenue of $375 million, up 13.5% sequentially; gross margin of 48%; non-GAAP operating expenses of approximately $87.5 million; GAAP EPS of $1.29; and non-GAAP EPS of $1.42. Management said the non-GAAP OpEx increase is temporary and tied to variable incentive compensation accrual. The company expects above-average demand into fiscal 2027 but gave no full-year FY2027 revenue guide, while offering a verbal FY2027 TCB range of $150 million to $200 million.
Trajectory
KLIC's disclosed revenue path stepped from $199.6 million in Q1 FY2026 to $242.6 million in Q2 and $330.4 million in Q3; Q4 is guided to $375 million. The ramp is led by general semiconductor and memory, while management says the customer mix is less favorable. Gross margin was 49.5% in Q2, then 47.8% in Q3, with Q4 guided at 48%.
The Model
The model projects FY+1 revenue of $1,087.2 million and EBITDA of $200 million, an 18.4% margin, rising to $1,280 million of revenue and $273 million of EBITDA, a 21.3% margin, in FY+2. The near-term path is anchored by the reported FY2026 ramp and Q4 guide; the FY+2 step assumes continued growth in advanced packaging and wire bonding.

Projections are the median of 5 independent model runs. The model’s revenue sits 0.8% below analyst consensus.
For Q4 FY2026, management guided revenue of $375 million, up 13.5% sequentially; gross margin of 48%; non-GAAP operating expenses of approximately $87.5 million; GAAP EPS of $1.29; and non-GAAP EPS of $1.42. Management said the non-GAAP OpEx increase is temporary and tied to variable incentive compensation accrual. The company expects above-average demand into fiscal 2027 but gave no full-year FY2027 revenue guide, while offering a verbal FY2027 TCB range of $150 million to $200 million.
What Could Go Right — and Wrong
- FY2027 TCB revenue lands within or above management's verbal $150–200 million range.
- HBM system completes qualification and generates repeat volume orders in FY2027.
- Hybrid bonding tool delivery in the first half of FY2027 is accepted, confirming a next-generation platform.
- Gross margin returns toward the prior 49–50% commentary while revenue remains high.
- Customer concentration broadens as the upcycle matures beyond the top three at 39.4%.
- A top customer loss or slowdown; Tianshui Huatian was 16.9% of H1 revenue and 29.6% of receivables.
- China demand or export-control disruption; H1 FY2026 revenue is highly concentrated, with Tianshui Huatian Technology Co., Ltd at 16.9% and 29.6% of receivables.
- Advanced Solutions disappoints and FY2027 TCB comes in below the verbal $150–200 million range.
- Inventory purchase obligations of $338.9 million due in fiscal 2026 become a margin and earnings drag if demand cools.
- Gross margin stays below 48% and OpEx remains elevated into FY2027.
Looking Ahead
For the next 12 months, the source set is anchored by the Q4 FY2026 report, expected in November 2026, and management's promise of more second-half fiscal 2027 color on the November call. The first half of fiscal 2027 carries the Singapore TCB capacity completion target and planned first hybrid bonding tool delivery, alongside HBM qualification and the vertical-wire ramp.
- November 2026Q4 FY2026 results — Tests $375M revenue, 48% gross margin, and $87.5M non-GAAP OpEx guidance.
- November 2026 callSecond-half FY2027 color — Management said it will likely give more visibility into 2H FY27.
- 1H FY2027Singapore TCB capacity completion — Capacity targeted to support approximately $400M of Advanced Solutions revenue.
- 1H FY2027Hybrid bonding tool delivery — First customer tool delivery planned; customer acceptance is the signal.
- FY2027HBM qualification outcome — Delivered Dec 2025; volume production potential cited for FY2027.
- FY2027TCB revenue toward range — Track actual TCB disclosures against verbal $150–200M range.
