BofA: Analog Semiconductors

Sector Overview & Cycle Recovery

> Shift to Restocking: The analog semiconductor sector is transitioning from inventory normalization to demand restocking, driven by improving unit demand and secular tailwinds.

> Strong Second Half Expected: Unlike previous cycles that typically saw seasonal moderation in the second half of the year, management teams project a stronger 2H26 supported by healthier demand trends and better backlog visibility.

> Accelerating Sales: Diversified semiconductor sales growth at top suppliers is projected to accelerate to 19% in CY26E from just 1% in CY25E, reaching a total market size of $175 billion.

Segment Breakdown

> Industrial / AI: Broad industrial markets are in the early stages of a cyclical recovery. Secular growth vectors like AI infrastructure (power delivery), aerospace & defense, and automation remain highly robust. Most AI-exposed revenue streams are on track to grow 50% to 100%+ this year.

> Automotive: Fundamentals remain mixed with strong performance in China outpacing sluggish trends in Europe and stable conditions in North America. Growth is primarily driven by content gains (such as silicon carbide, ADAS, and software-defined vehicles) rather than expansion in vehicle production units.

> Microcontrollers (MCUs): Facing the deepest correction previously, MCUs now display the highest cyclical upside as industrial and embedded customers begin rebuilding orders.

Margins & Valuations

> Gross Margin Drivers: Earnings leverage is shifting away from simple inventory digestion toward multi-quarter factory utilization recoveries, product mix optimizations, and selective pricing power/increases to offset inflationary costs.

> Operating Margins: Most suppliers have completed major restructuring efforts. Operating expense growth is expected to stay well below revenue growth, allowing for sharp operating margin expansion through CY28E.

> Reasonable Valuations: Despite strong year-to-date performance, diversified semis have remained resilient through recent sector pullbacks. The group trades at a median 25.6x CY27E P/E (34% premium to its 5-year median), which compresses to a 10% premium on CY28E numbers as normalized earnings materialize.
