A strong fundamental stock that underperformed the market for a long time before finally outperforming/achieving it’s fair value?

Hi everyone,

I'm curious, I was wondering what stocks you know of that had (or still has) strong fundamentals and growth, but had underperformed the market due to the market undervaluing the stock, and then eventually surpassed the SP500 and/or reached its fair value? Would be interesting to hear which companies and why this was happening.
