FormFactor's role as a chip-test supplier to Nvidia underpins the case, and the chart recently formed a double bottom at the 200-day moving average. x.com 

FormFactor's rebounding free cash flow and operating margins suggest it is making the right moves in the tough, competitive chip-testing segment. Against ASML, the segment's beast, FormFactor has better growth and a 40% lower PEG. The chart is ready to move again, with a pattern target of 143 versus an all-time high around 160. x.com  x.com 

FormFactor is expensive against its earnings, trading at about 38x when chip-equipment makers usually get 18x. Fair value sits at $60.06 to $76.44, or 18x next year's $3.79 EPS give or take 12%, so at $145.97 the price is about 91% above fair. The valuation also leans on the forecast, with forward EPS 177% above trailing. This is a levels-only read off reported earnings and revenue estimates, with no fundamental work. x.com 

FormFactor sits in test and packaging, the best corner of semiconductors this year, where much quiet money is being made in the layer that makes compute functional. It makes the probe cards that test chips and ranks first globally in test subsystems. Last quarter set a revenue record, up 32%, with gross margin up 510 basis points to 49% and EPS beating by 33%. DRAM probe card revenue hit a record on HBM, a product sold out through 2030. x.com 

FormFactor is rated Buy amid the AI sector crash because it is important for HBM, advanced packaging and CPO, where its testing raises yields. Foundry test intensity is only set to increase as production grows. x.com 

FormFactor's 2030 target model implies either a still-high multiple in 2030 or disappointing share-price gains over the next few years. The model, cited via Citi and apparently management's own, targets $1.6B revenue, 55% gross margin and $5 EPS. The modeled TAM may prove higher, but a margin of safety means assuming today's high multiple won't stay as high. x.com  x.com  x.com  x.com 

FormFactor's production-ready wafer-level CPO probe gives it a test opportunity at a major foundry, but that business depends on one customer. CEO Mike Slessor says the CPO piece flows through a foundry worth 10% of sales; he did not name it, though an analyst named TSMC. Triton tests photonic wafers before stacking; post-stack test remains difficult. FormFactor expects CPO test revenue to significantly exceed $20m this year and estimates a $400m market by 2030. x.com 

FormFactor offers attractive risk/reward as AI probe-card share rises while the stock has corrected 38% to 25x 2027E P/E, versus 33x for MPI and 42x for Technoprobe. Q2 beat with $258.2M revenue and 53.3% gross margin, and Q3 is guided to ~$270M at 54%. Catalysts include an expected 10%+ share on Nvidia Rubin, Intel's 18A ramp lifting server CPU probe demand and pricing by 20-30%, record HBM revenue expected in Q4 and co-packaged optics revenue hitting the high end of FY26 guidance by Q3. x.com 

Amtech Systems' 131x trailing P/E hides an advanced-packaging turnaround. Its TrueFlat technology on Pyramax vacuum reflow platforms tackles substrate warpage in stacked dies and HBM, and these systems are over 30% of thermal segment revenue, heading past 40%. A semi-fabless shift under CEO Robert Daigle lifted gross margin to 47.7% on Q2 revenue up 31%, and its silicon carbide polishing consumables are rebounding. Institutions buying a $60M raise at $20.50 signal significant upside. x.com
