Will Amkor's gross margin exceed 14% in any quarter of H1 2026?

Q1 2026 guided at 12.5-13.5% gross margin — well below the 14% threshold. Equipment investment is front-end loaded in H1 2026, meaning depreciation pressure peaks before revenue ramps in H2. For Q2 to exceed 14%, gross margin would need to improve 50-150bps sequentially from Q1, which requires revenue growth to outpace depreciation. Given that the H2 revenue ramp is the intended offset, Q2 is still in the depreciation pressure zone. Vietnam breakeven helps (~90bps) but is insufficient alone. FY2025 full-year was 14.0% and that included a $30M Q4 asset sale benefit. Without that benefit, underlying margin was closer to 13.5-13.8%.

The question asks about any quarter of H1 2026 exceeding 14%. Q1 is guided well below at 12.5-13.5%. Q2 would need to recover significantly, but the depreciation from front-loaded equipment continues into Q2. Management's 30% incremental flow-through model means margin recovery requires strong revenue growth. Q1 2026 revenue guided at $1.6-1.7B (+25% YoY) is robust, but the CapEx load is overwhelming. R&D at $135M/quarter adds further compression. The most likely scenario is both Q1 and Q2 remain in the 12-14% range, with recovery to 14%+ not occurring until H2.

There is a non-trivial path to 14% in Q2. Vietnam breakeven removes 90bps drag. Improving pricing environment was cited as a margin driver. Seasonal Q2 tends to be stronger than Q1 in semiconductors. If revenue comes in above the guided range and the mix shifts favorably toward advanced packaging in Q2, margin recovery could be faster than the base case. However, the depreciation headwind from $1B+ in H1 equipment installation is structural. I assign about a 1-in-4 chance that favorable mix and pricing offset the depreciation enough to reach 14%.

Management explicitly guided Q1 at 12.5-13.5%, a 50-150bps drop from FY2025's 14.0%. The front-loading of equipment in H1 means Q2 faces similar depreciation pressure. The 30% incremental flow-through model would require ~$200M+ in incremental quarterly revenue above Q1 levels to add 150bps in margin. That scale of sequential improvement in Q2 seems unlikely. The margin recovery is designed to happen in H2 when HDFO programs ramp revenue against the already-installed equipment base.

The math is unfavorable for H1. FY2025 gross profit was $939M on $6.7B revenue (14.0%). Q4 2025 was 16.7% but included $30M asset sale — underlying was ~15%. Q1 2026 drops to 12.5-13.5% on depreciation. For Q2 to hit 14%, revenue needs to grow strongly while COGS growth from depreciation is contained. But equipment installation continues through H1, meaning depreciation additions continue. Japan facility optimization won't deliver its 100bps improvement until end 2027. Low probability.

The question is specifically about exceeding 14% in H1. Q1 is guided at 12.5-13.5%. For Q2, even with seasonal improvement, the depreciation headwind from 2.8-3.3x CapEx increase is massive. Management designed the investment cycle with H2 as the revenue recovery period. Expecting H1 margin recovery contradicts the company's own timeline. The only scenario for 14% in H1 is if equipment installation is delayed (reducing depreciation) while revenue outperforms — but delayed equipment would be a negative signal for H2 ramp.

Q1 guided 12.5-13.5%, well below 14%. Equipment front-loaded in H1 creates peak depreciation pressure. Margin recovery designed for H2. Low probability of hitting 14% in H1.

Management explicitly guided gross margin compression in Q1. The CapEx front-loading makes Q2 equally challenging. Vietnam breakeven helps but is insufficient to bridge a 50-150bps gap. The 14% target is achievable in H2 2026, not H1.

Q2 has a slightly better chance than Q1 given seasonal strength and potential early HDFO ramp. However, the structural depreciation headwind dominates. Improving pricing environment could help at the margin. Still below 25% probability.
