Amkor Q1 2026. Money For Nothing & Your Shares For Free

Brief

Amkor delivered a record Q1 2026 with $1.68 billion in revenue ( +27% YoY, -10.7% QoQ), driven principally by a 42% YoY jump in communications and stronger-than-expected end‑market performance outside of computing. Gross margin rose to 14.2% (up 230 bps YoY), producing $239 million of gross profit (+52% YoY); GAAP diluted EPS was $0.33 and net income attributable to Amkor was $83.4 million on 249.6 million diluted shares. CEO Kevin Engel highlighted progress on advanced packaging programs, improved factory utilization and margin initiatives; management says AI advanced‑packaging revenues are on track to triple YoY while capacity builds in Arizona and Vietnam. Investors initially sold off after the April 27 report—shares slid 8.63% to $71.36 amid an 80% YTD run and concern over reaffirmed $2.5–3.0B CapEx—though the stock recovered to $76.69 by May 12. Amkor also filed a $1 billion convertible senior notes offering to raise capital.

This was above the midpoint of guidance, driven by stronger-than-expected performance across all end markets, except computing, where the company saw softness in PCs and laptops. The communications end market was the largest contributor to year-on-year growth, increasing 42%.

Gross margin of 14.2% exceeded the high end of the Q1 guidance range, primarily due to favorable product mix, up 230 basis points YoY and down 250 basis points QoQ.

Gross profit for the quarter was $239 million, up 52% from last year due to increased volume and focused cost management.

Diluted EPS: $0.33 (GAAP) was up from $0.09 in Q1 2025, down from $0.69 in Q4 2025. Net income attributable to Amkor was $83.4 million on 249.6 million diluted shares.

According to recently appointed CEO Kevin Engel:

> “Amkor delivered a strong start to 2026 with record first quarter revenue driven by broad-based end market demand. During the quarter, we progressed key customer programs in Advanced packaging, improved utilization across our factory network, and made continued progress on our margin initiatives, demonstrating our ability to execute effectively in a dynamic industry environment.”

Immediately following the release on April 27, AMKR shares tumbled 8.63% to $71.36 in after-hours trading. The sell-off was likely driven by profit-taking after an 80% YTD run and investor anxiety over the reaffirmed $2.5B –$3B capital expenditure guidance.

However, as of May 12, 2026, the stock has clawed back those losses, now trading at $76.69 as the narrative likely shifts from “CapEx pain” to “strategic dominance” via the Arizona and Vietnam expansions. Oh, and AI advanced packaging revenues on track to triple YoY doesn’t hurt either.

There days after the earnings call, Amkor dropped a bombshell with the offering of $1 billion in convertible senior notes. It’s effectively the lenders giving Amkor a $1 billion interest free loan in the expectation that they get a windfall return in the form of Amkor shares.

Let’s dig in…
