Heartland Value Plus Fund stated the following regarding Silicon Motion Technology Corporation (NASDAQ:SIMO) in its second quarter 2025 investor letter:
“Silicon Motion Technology Corporation (NASDAQ:SIMO) — a leading maker of memory components used in PCs, smartphones, data centers, and industrial applications — also took a hit earlier this year, on tariff concerns and as investors questioned the capex needs of large-scale cloud service providers known as hyperscalers. SIMO shares sank more than 30% from March 24 to April 21, on fears that further weakness in consumer spending could impact PC and smartphone sales. Since then, however, hyperscalers have confirmed robust datacenter capex growth, as consumer sentiment has rebounded somewhat. Since April 21, SIMO shares have surged more than 70%.
We continue to hold SIMO because we believe it is in the early days of a re-rating from its upcoming growth and margin expansion as data center products evolve to become a larger percentage of the company’s total revenue mix. Silicon Motion has historically leaned more to the consumer electronics side of the business, which is marked by trailing edge technology and lower margins. However, throughout the recent downcycle the company made a push into higher-margin, leading-edge applications driven by hyperscaler demand. On its last earnings call, management announced it was partnering with Nvidia on memory storage banks.
Due to the longer-than-usual down cycle for consumer electronics companies, though, our analysis indicates that SIMO remains meaningfully undervalued. The stock currently trades at $75.17 a share, but we believe the company should be valued at $90. That’s based on a 13X EBITDA multiple plus an anticipated $160 million cash settlement from SIMO’s ongoing arbitration with MaxLinear surrounding the termination of a proposed merger agreement two years ago.”
