FormFactor (FORM) is moving across several Russell indices after the latest annual reconstitution, shifting from small cap focused benchmarks into the Russell 1000 and Russell Midcap groupings.

See our latest analysis for FormFactor.

The index reshuffle comes after a sharp pullback in FormFactor’s share price over the past week, with a 7 day share price return of down 17.69% and a 1 day move of down 3.98%. This comes against a much stronger backdrop where the year to date share price return is 100.49% and the 1 year total shareholder return is 241.59%, signalling that long term momentum has been strong even as near term sentiment cools.

After a sharp pullback, yet very strong 1 year and year to date gains, FormFactor now sits at a crossroads. Is it worth stepping in after this reset, or does patience for a cheaper entry make more sense as valuation is tested next?

Most Popular Narrative: 18% Undervalued

FormFactor's most followed valuation narrative places fair value at $144.67 versus the last close of $118.67, framing the recent pullback inside a still-upbeat long term story.

Accelerating adoption of generative AI, high-performance computing, and HBM DRAM in data centers is driving substantial increases in test complexity and intensity. FormFactor's differentiated probe cards and early leadership in HBM4 chiplet testing position the company to benefit from higher ASPs and revenue growth as these markets scale. (Impacts: Revenue, potential margin improvement)

Read the complete narrative.

Want to see what underpins that gap between price and fair value? The narrative leans on faster top line growth, sharply higher margins, and a reset earnings multiple. The exact mix of those assumptions is where the story really gets interesting.

The narrative framework uses a discount rate of 11.08% and ties FormFactor's fair value tightly to expectations for AI driven demand, rising profitability, and how much investors might be willing to pay for those future earnings in a few years.

Result: Fair Value of $144.67 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, for this FormFactor narrative to hold, margin pressure from tariffs and product mix, or weaker than expected HBM and AI test demand, could quickly challenge those assumptions.

That 18% undervalued narrative for FormFactor sits awkwardly next to current market ratios. The stock trades on a P/E of 135.4x versus 93.5x for peers and 65.3x for the wider US Semiconductor group. The fair ratio points to 77.2x as a level the market could move toward.

In plain terms, investors are paying far more for each dollar of FormFactor earnings than for peers or the fair ratio suggests. This raises the question of whether expectations or valuation risk are higher than that optimistic narrative implies.
