<li>Like other automotive/industrial semi vendors, Diodes guides 4Q23 sales of 20% q/q and 35% y/y decline (miss by 21%) and weaker gross margin/operating margin of 35%/7% (miss by 5ppts).</li>
<li>The company sees 4Q23 sales decline of 20% mainly from 19% of automotive and 26% of industrial customers due to customer inventory cut coupled with year-end distributor inventory management. </li>
<li>We expect this adjustment for automotive/industrial IDMs to last for at least 6 months and suggest our clients to avoid these names unless valuation becoming attractive.  </li>

With No Surprise, Diodes Guides Automotive/Industrial Semi Demand to Fall over 20% Q/Q

<ul>
<li>During MOI correction period, global semi equipment and manufacturing vendors might under-perform semi product companies on sales/earnings and share price performance in next 6 months given utilization remains below 80%.</li>
<li>A healthy MOI correction in PC/smartphone semi might result in global logic MOI to fall to 3.7-3.8 months in 3Q23, down 15% q/q and 8% y/y, heading to historical low. </li>
<li>China fabless reduced MOI to 6.4 months in 3Q23, down 16% q/q and 26% y/y. Although 2x over 3.5 months low, we expect 4-5 months in future due to restrictions.</li>

More Signs of Fab Utilization Recovery Starting Mid-2024 Post Current MOI Correction

Equity Bottom-Up

<ul>
<li>We see early signs of recovery in PC and smartphone markets, stable server market (strengths in AI server, stable in non-AI server market), but weaknesses in automotive and industrial.</li>
<li>We expect the PC semi market recovery of more than 10% y/y in 2024/2025, driven by inventory rebuild and silicon contents increase by adding AI into PC.</li>
<li>We expect the smartphone semi market recovery of 7-8% y/y in 2024/2025, driven by inventory rebuild and adopting 3nE foundry node. But, Huawei/HiSilicon will take some of the growth.</li>

<li>Silergy foresees the demand will be larger than capacity in 2022. Silergy expects Auto, Sever Mother-board, SSD and others should be showing a strong demand in 2022.</li>
<li>The shipment lead-time is controlled around 5~6 months, which indicated that the demand is strong for 2022~23.</li>
<li>The generation 3rd will be optimized until 2026. Silergy will need some new suppliers for generation 4th in 2023. In 2026, generation 3rd &amp; 4th will dominate Silergy’s revenue. </li>
