Hook & thesis
Cohu Inc (COHU) is one of the quieter beneficiaries of the AI silicon cycle. Its test and handling equipment addresses a niche but critical step in semiconductor manufacturing: verifying high-performance chips and memory that power large language models and other AI workloads. Recent quarters show growing demand tied to wafer-fab and AI-related segments, management has flagged an HBM product revenue opportunity, and the stock has corrected from its late-June highs. That combination creates a tactical long opportunity with defined risk control.
The basic thesis: end-market demand for AI chips and the associated HBM memory creates a multi-quarter revenue stream for Cohu's test tools. The market has partially priced in cyclic risk and near-term margin noise - shown by volatile analyst actions and insider profit-taking - but Cohu still generates free cash flow and trades at a market capitalization that leaves room for upside if HBM/design-win momentum continues. I therefore propose a disciplined long with a clear stop and staged upside targets.
What Cohu does and why the market should care
Cohu makes back-end semiconductor capital equipment - test and handling systems and interface products that sit at the wafer-to-packaging/test stage. These machines are required for functional and burn-in testing of advanced logic and memory devices. As leading customers ramp AI accelerators and HBM memory stacks, demand for specialized test systems and high-throughput handlers rises in step.
Why that matters now: AI workloads are increasing adoption of HBM and other advanced packaging. Management expects HBM-related product sales to contribute meaningfully (management cited an HBM sales range of $15 - $20 million for the full year). That incremental revenue is significant for a company that reported quarterly revenue in the low hundreds of millions.
Recent financial and market signals
- Revenue momentum: In the latest reported quarter, Cohu posted revenue of $122.2 million - up roughly 30% year-over-year - demonstrating tangible top-line acceleration tied to end-market improvements.
- Free cash flow positive: Trailing free cash flow was $40.167 million, and enterprise value is roughly $2.68 billion, suggesting the company is generating real cash versus earlier cycle losses.
- Valuation multipliers: Price-to-sales sits near 5.39 and EV-to-sales near 5.57, with a P/B of about 3.38. GAAP EPS is negative (earnings per share -$1.18) and the trailing P/E is negative, reflecting cyclical earnings swings.
- Share-price action: The shares ran to a 52-week high of $74.60 (06/30/2026) after a strong multi-quarter move, then pulled back. The 52-week low was $17.795 (07/31/2025) which illustrates the stock’s cyclicality.
- Insider & analyst activity: A director sold ~10,257 shares at $44.85 in May (profit-taking after a strong run), while brokers have oscillated between upgrades and downgrades over the last year as the cycle evolved.
- Market mechanics: Average daily volume sits around 1.34 million shares (30-day average ~1.46M), and short interest has been non-trivial (about 8.04 million shares as of 06/30/2026 with days-to-cover around 5.18), which can amplify moves in either direction.
Valuation framing
Cohu’s market cap is roughly $2.42 billion and enterprise value about $2.68 billion. On an EV/sales and P/S basis the stock is not cheap at face value (EV/sales ~5.6, P/S ~5.4). Those multiples imply the market is pricing in a reasonable amount of future revenue growth and margin recovery.
That said, the company generates positive free cash flow ($40.2 million), and its market cap reflects a recovery story rather than an early-stage speculative valuation. The negative EPS is a caution - the company has posted adjusted losses in quarters - but the combination of improving top-line trends (30% YoY in one recent quarter) and design-win commentary around HBM means the multiples could compress to more attractive levels if the revenue ramp persists and gross margins expand toward management’s target range.
Catalysts to watch
- Quarterly results and guidance - Any beat on revenue or margin guidance that points to a sustainable HBM/AI testing ramp will be an obvious re-rating event.
- Design wins / order announcements - New design-win announcements or sizable design-win order conversions into booked orders materially de-risks the revenue outlook.
- HBM product ramp - Management has called out HBM sales potential of $15 - $20 million for the year; proof of that ramp will change forward revenue trajectories.
- Industry capacity constraints - If wafer-fab investment re-accelerates or memory demand surprises higher, equipment vendors like Cohu typically see order acceleration with 1-3 quarter lead times.
- Analyst revisions - Upgrades and target raises from specialty semiconductor equipment analysts would bring more attention and could push the stock higher given relatively low institutional following.
Trade plan (actionable)
| Metric | Value |
|---|---|
| Trade direction | Long |
| Entry price | $51.25 |
| Stop loss | $47.00 |
| Target price | $65.00 |
| Horizon | Long term (180 trading days) - allow multiple quarters for HBM/design-win revenue to show through |
| Risk level | Medium |
Rationale: I use $51.25 as an exact entry aligned with current liquidity and intraday tradeability. The $47 stop is beneath recent short-term moving averages and gives the trade room for headline-driven noise while protecting capital if cyclical weakness resumes. The $65 target captures a move back toward the mid-portion of the stock’s recent trading range and assumes a successful HBM revenue ramp and margin recovery; it's also a reasonable milestone before reassessing upside toward the 52-week highs.
Why this is not a speculative punt
Cohu is a capital-equipment vendor with recurring service and spare-parts revenue plus incremental design-win-led order flow. The company generated meaningful free cash flow and consecutive quarters of revenue growth in recent reports. That differentiates it from early-stage hardware plays: wins convert to booked orders and then recognized revenue on a relatively observable cadence. The path to value here is clear - bookings translate into revenue and margins as the product mix shifts to higher-margin HBM and AI-related test work.
Risks and counterarguments
- Semiconductor cyclicality - The equipment cycle is volatile; an industry slowdown or inventory correction at major customers could push orders out and compress margins. A clear sector pullback would likely breach the stop.
- Near-term margin pressure / earnings volatility - Cohu has reported adjusted losses unexpectedly in the past (an adjusted loss of $0.15 per share in one quarter), and management’s margin recovery commentary is a forecast, not a guarantee.
- Valuation risk - The company trades at roughly 5.4x sales and negative P/E; if the market decides to re-price semiconductor-equipment vendors downward due to macro risk, COHU could fall materially even with decent operational execution.
- Execution and competition - Converting design wins into high-volume production tools is an execution task; competitors or technical setbacks could delay revenue realization.
- Insider selling & sentiment - Directors have taken profits recently, and analysts have swung between buy and neutral; mixed sentiment could cap upside until consistent beats arrive.
Counterargument: The most persuasive counterargument is valuation. At current multiples and with negative EPS, Cohu is priced for good execution and continued AI-driven growth. If that growth disappoints or semiconductor capex softens broadly, the stock has downside. Traders should therefore respect the stop and expect earnings to be the primary re-rating mechanism.
What will change my view
- Positive trigger - New multi-million-dollar design wins for HBM or AI test tools that convert to booked orders and are referenced on the upcoming quarterly call would materially increase conviction.
- Negative trigger - A guidance cut, another unexpected adjusted loss, or a meaningful decline in booked orders would force me to abandon the long and consider short or neutral stances.
Practical trade management
Enter at $51.25, size the position so the $47 stop represents a pre-determined percentage of portfolio risk (e.g., 1-2% of capital). If Q3/Q4 results show HBM revenue and the company reiterates margin expansion toward mid-40s gross margin guidance, consider trimming into strength and moving the stop higher to protect gains. If the stock reaches $65, take partial profits and re-evaluate whether the next leg to the 52-week high is justified by fresh fundamental evidence.
Bottom line
Cohu is an underfollowed, mid-cap equipment supplier that stands to benefit from the AI-driven need for HBM and advanced test tooling. The combination of improving revenue, positive free cash flow, and a visible HBM sales path offers an asymmetric trade when risk is controlled with a tight stop. This is a tactical long - not a buy-and-forget - designed for investors who will monitor bookings, margins and design-win conversion over the next several quarters.
Key dates & cues to watch
- Quarterly earnings release and conference call - primary catalysts for upside or downside.
- Design-win/order announcements - near-term confirmation of the HBM ramp.
- Analyst revisions and any large institutional filings that change the shareholder base materially.
