Semtech (SMTC) Could Be 17% Undervalued As Strong Earnings Lift The Story

Semtech (SMTC) has moved back into focus after reporting stronger non-GAAP earnings, guiding for higher Q3 metrics, and rolling out new connectivity products alongside fresh security and networking partnerships.

The recent run in Semtech’s shares has been sharp, with a 30-day share price return of 36.84% and a 1-day move of 3.05%, even though the 7-day share price return declined 2.07%. That short-term surge sits on top of a very large 3-year total shareholder return of about 7x and a 1-year total shareholder return of 183.14%. This points to momentum that has been building as earnings, guidance and product news accumulate around the stock rather than fading quietly into the background.

As data rates move from 400G to 800G and 1.6T, Semtech stands to capture significant revenue and margin expansion from new content per deployment.
