Semiconductors Earnings Recap: Micron (MU) Soars, Onsemi (ON) Stumbles
Micron Technology (MU) shares fell 6.69% Tuesday despite reporting record quarterly earnings of $25.11 per share, as investors locked in profits following a massive rally. The company outperformed consensus estimates of $20.98 per share by a significant margin.

The cohort

The semiconductor sector is currently grappling with an AI-memory decoupling narrative. While high-bandwidth memory (HBM) demand remains at record levels, broader cyclical concerns are pressuring high-beta names.

Market participants are weighing the sustainability of AI-driven growth against potential macroeconomic headwinds.

  • Micron Technology (MU): Reported EPS of $25.11 vs. $20.98 consensus estimate.
  • Micron Technology (MU): Reported revenue of $41.46B vs. $35.91B consensus estimate.
  • Onsemi (ON): Issued Q2 2026 revenue guidance of $1.5B–$1.6B, missing the $1.6B consensus estimate.
The cohort

Standouts

Micron Technology delivered a transformative performance this quarter, driven by strategic customer agreements (SCAs) that provide long-term revenue visibility.

These non-cancellable agreements effectively establish a pricing floor, mitigating the historical volatility associated with the memory cycle.

  • Rosenblatt Securities analyst Kevin Cassidy expects a continued beat-and-raise cycle for Micron.
  • Cassidy noted that broadening AI demand and constrained supply will likely extend the current memory upcycle.
  • Micron's ability to lock in pricing floors is viewed as a structural shift in the company's business model.

Disappointments

Onsemi (ON) provided a more cautious outlook, highlighting softening demand in non-AI segments.

The company's guidance suggests that the industrial and automotive sectors are not yet participating in the AI-fueled recovery seen elsewhere in the chip industry.

  • Onsemi's Q2 2026 revenue guidance of $1.5B–$1.6B fell below the $1.6B consensus expectation.
  • The miss signals potential inventory corrections or slowing demand in legacy automotive and industrial power management segments.
  • Investors reacted negatively to the guidance, reflecting heightened sensitivity to growth deceleration in non-AI semiconductor markets.

What to watch next week

The market will focus on whether the profitability floor established by Micron's new long-term contracts can sustain valuations in a high-rate environment.

Investors are also looking for evidence that other memory and chip peers can replicate this model to mitigate cyclical volatility.

  • June 30, 2026: Continued monitoring of sector-wide profit-taking and rotation trends.
  • July 2, 2026: Focus on broader market breadth and interest rate sensitivity for high-beta growth stocks.
  • July 7, 2026: Upcoming industry-wide supply chain updates regarding HBM capacity utilization.
What to watch: Market focus will shift to whether the profitability floor established by Micron's new long-term contracts can sustain valuations above the $476 billion market cap level.
