Hon Precision Raises Capacity CAGR to 50%; CPO and SLT Upside Justify OW

Core Thesis

Hon Precision has lifted its 2026-2028 capacity expansion CAGR to 50%, backed by a newly purchased facility in Daya, Taichung (Plant 4) that begins releasing capacity from 4Q26. 1Q26 EPS of NT$25.7 beat consensus by 13% (+62% YoY, +13% QoQ), driven by AI/HPC mix rising to 78% of revenue. The structural shift toward longer test times, additional test insertions (CPO, SLT), and spec upgrades is accelerating demand for Hon’s handlers, where it holds >70% AI/HPC market share. 2026/27/28 EPS estimates were raised 11%/15%/21% to NT$129.19/222.56/371.52. With competitive concerns in GPU and CPO FT handler eliminated, Hon is positioned for 76% EPS CAGR (2025-28e).

What the Market May Be Underestimating

Three incremental drivers are not fully priced: (1) CPO Insertion 4E is a net-new test stage—Hon is the sole supplier, targeting equipment release in 4Q26 and scaled shipments from 1Q27, covering both electrical testing (2025-26) and concurrent optical/electrical testing (2027+). This opens a TAM that did not exist in prior cycles. (2) SLT handler breakthrough into leading GPU customer—Hon has sent samples to the top GPU player (NVIDIA) and will disclose details next quarter. It also begins shipping new SLT handlers for Venice CPU from 3Q. SLT adoption adds high-ASP, high-margin revenue. (3) Non-AI expansion in Europe—dual-temp HPC handlers shipping this year, auto tri-temp handlers under qualification. These broaden the customer base beyond hyperscalers.

Evidence Chain

• Capacity evidence: Company guided 50% CAGR in capacity expansion for 2026-28e. New Plant 4 near Daya needs one quarter for setup, with capacity release starting 4Q26. This directly supports the 50% Y/Y capacity goal into 2028.
• Financial evidence: 1Q26 revenues NT$10,725mn (+81% YoY), gross margin 56.2% (up 3.9ppt QoQ), operating margin 50.0%. EPS NT$25.7 was 14% above MSe and 13% above consensus. Strong AI/HPC mix (78%) drove outperformance.
• Product evidence: Dual-temp FT handler and tri-temp SLT for AI5 start shipping in 3Q to Taiwanese and Korean OSATs. Google CPU Axion 2 expected to ramp strongly in 2027. CPO ASIC switch MP begins 3Q26. For next-gen CPO (Insertion 4E), Hon has already secured sizable orders.
• Competitive evidence: Industry checks confirm Hon is the sole handler supplier for Insertion 4E. In SLT, sample sent to leading GPU customer—implies credible threat to incumbents. No competing solutions in GPU or CPO FT handler have emerged.

Key Risks and Disagreements

• AI demand slowdown: If hyperscaler capex decelerates or chip design shift reduces test intensity, the 50% capacity buildout could lead to underutilization and margin pressure.
• Competitive encroachment: Cohu, Chroma, or others could develop competitive CPO FT or SLT handlers, eroding Hon’s >70% share. The CPO field includes Chroma in Insertion 4O (optical), but Hon is sole in 4E—any technology overlap risk.
• Margin trajectory: Gross margin expanded to 56.2% in 1Q26 (+3.9ppt QoQ) but remains below 60%+ street expectations for 2027e. Product mix shift toward tri-temp SLT and CPO could lift margins, but customer pricing power in volume orders is a risk.
• European qualification delays: Auto tri-temp handler under qualification may take longer than expected, delaying EU revenue contribution.

Valuation and Trade Implication

Target price raised from NT$5,000 to NT$10,008, based on a residual income model (COE 9.8%, intermediate growth 15%, terminal growth 4%, payout 65%). This implies 45x 2027e P/E, which is reasonable given the 76% EPS CAGR (2025-28e). The prior PT was rendered obsolete by capacity guidance; the new PT reflects both higher near-term estimates and a structurally higher terminal value from CPO and SLT penetration. Downside to bear case (NT$5,000, 23x 2027e) assumes 20% revenue CAGR and no CPO wins—a low-probability scenario given current order visibility. Upside bull case (NT$16,000, 70x 2027e) assumes 100% revenue CAGR and margin >70%. Maintain Overweight.
