Win Semiconductors' September-quarter revenue and gross margin surged 19% and 840 basis points sequentially to TWD 4.5 billion and 26.9%, respectively. Shares surged 10% on Friday as management turned more upbeat about gross margins and infrastructure product growth.

Win Semiconductors' second-quarter 2025 revenue and gross margin grew 6% and 173 basis points sequentially to TWD 3.8 billion and 18.5%, respectively. Currency headwinds led to revenue being short of guidance and kept gross margin at its lower range.

Win Semiconductors' first quarter of 2025 revenue and gross margin fell 4% and 371 basis points sequentially to TWD 3.6 billion and 16.7% respectively, in line with guidance. The changes are due to Chinese subsidies driving demand for more low-margin power amplifiers, or PAs, for smartphones.

We slashed our fair value estimate for narrow-moat Win Semiconductors to TWD 130 from TWD 202 as management alluded to weak Android smartphone demand in coming quarters. At the same time, fellow radio frequency chip supplier Qorvo painted a damning picture of the structural Android phone outlook. This leads us to no longer assume the cluster in Kaohsiung will resume work before 2028 in the long term, and lower gross margins from a worse product mix. Although Win Semi’s shares are down more than 20% year to date, we think they are now fairly valued as a shift to low-end Android phones is less favorable for the company. Nevertheless, growth is still likely thanks to autonomous driving demand.

We cut our fair value estimate on narrow-moat Win Semiconductors to TWD 202 from TWD 245, given disappointing management guidance for the third quarter and our expectation that expansion in Kaohsiung will be downsized in the long term. Despite this, Win Semi remains undervalued amid a boost to the smartphone outlook by a pipeline of artificial intelligence features, and structural growth demand for optical components. We view Win Semi’s more cautious approach to capital expenditure as buying time for repairing its balance sheet and better maneuvering future cycles.

Win Semiconductors, or Win Semi, intends to secure its leadership in RF contract manufacturing by expanding capacity, developing GaAs improvements, selling new materials and exploring applications. It boasts almost 70% market share in GaAs foundries, with the next two largest peers at 10%-15% combined. The company has been successful in reducing reliance on mobile products, currently making up less than 40% of the business. Base stations and other infrastructure products make up the second-largest group.

We retain our fair value estimate for Win Semiconductors of TWD 245 as we believe a milder increase in the second half of 2024 will follow the upbeat first-quarter performance. Win Semi is undervalued, in our view, as the market remains unconvinced of a smartphone recovery and is focusing on competitor expansion in the near term rather than structural growth in optical components demand. Win Semi’s mediocre balance sheet may be improved disproportionately amid China’s smartphone recovery, triggering a rerating in the stock.
