FormFactor (FORM) is back in focus after reporting second quarter results and updating its near term outlook, giving investors fresh data on sales, profitability, and expectations for the coming quarter.

Despite FormFactor’s solid earnings update and new partnership announcements, the share price has fallen 26.4% over the past week and 42.1% over the past month. However, year to date the share price return is up 41% and the 1 year total shareholder return is 142.5%, so momentum has recently cooled after a strong run.

Bulls point to FormFactor’s profit jump and Taiwan partnership, while bears focus on the sharp pullback in the share price. Which side does the current valuation evidence support next?

Most Popular Narrative: 42.3% Undervalued

FormFactor's most followed narrative pegs fair value at $144.67 per share compared with the last close of $83.45, which frames a wide valuation gap that hinges on AI driven chip testing demand and execution at new manufacturing sites.

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)

Curious what earnings path and margin profile sit behind that fair value and discount rate assumption. The narrative leans heavily on compound revenue growth, rising profitability and a slimmer valuation multiple than many headline AI hardware stocks.

Result: Fair Value of $144.67 (UNDERVALUED)

However, FormFactor’s story is not risk free, with margin pressure from product mix and higher operating costs, as well as exposure to U.S. and China trade policy changes.

Another View on FormFactor’s Valuation

The analyst narrative leans on a fair value of $144.67 per share, yet FormFactor currently trades on a P/E of 95.2x. That is far above the US Semiconductor industry on 47.3x, its peer average of 73.1x, and even a fair ratio of 77.4x, which suggests meaningful valuation risk if expectations slip. How comfortable are you paying that kind of premium for this growth story?
