ON Semiconductor's Inventory Correction Narrative Finally Gets Its Proof Point

On Semiconductor reports first-quarter 2026 earnings after market close on May 4, with Wall Street expecting $0.61 per share on revenue of approximately $1.53 billion. The central question is whether the company's strategic pivot toward AI data centers and intelligent power solutions can offset persistent weakness in automotive and industrial end markets—and whether management's aggressive $6 billion share repurchase program signals genuine confidence or a defensive posture amid cyclical headwinds. With the stock up 146% over the past year and trading at stretched multiples, investors will scrutinize both near-term execution and the sustainability of margin expansion initiatives.

Part 1: Earnings Preview

On Semiconductor is a leading supplier of intelligent power and sensing technologies, specializing in silicon carbide (SiC) and power management solutions for automotive electrification, industrial automation, and AI data centers. The company has undergone a strategic transformation to focus on high-growth, high-margin segments, positioning itself as a critical enabler of electric vehicle adoption and next-generation data center infrastructure.

The company reports Q1 2026 results after market close on May 4, with consensus expecting $0.61 per share and revenue of approximately $1.53 billion. This represents a 10.91% increase from the $0.55 reported in Q1 2025, though it follows the $0.64 delivered in Q4 2025. Year-over-year, the estimate reflects improving fundamentals as the company laps easier comparisons and benefits from its operational restructuring.

Three key themes define this earnings story:

AI Data Center Momentum: ON delivered over $250 million in AI data center revenue in 2025, with management projecting continued growth in the high teens for Q1. The company's content per next-generation NVIDIA 800V rack is approximately 11 times greater than older designs, positioning ON as a critical supplier to the AI infrastructure buildout. Investors will watch for design win updates, revenue trajectory, and whether the AI opportunity can offset cyclical weakness elsewhere.

Automotive and Industrial Recovery: After eight consecutive quarters of year-over-year declines, industrial revenue finally turned positive in Q4 2025 (up 6% YoY), while automotive revenue stabilized. Management indicated most automotive inventory digestion is "largely behind us," but the pace of recovery remains uncertain given softer EV demand globally. The company's strategic exits from non-core revenue streams (approximately $300 million annually) complicate the growth narrative, making organic trends harder to discern.

Margin Expansion and Capital Return: ON's "Fab-Right" manufacturing rationalization reduced capacity by 12% in 2025 and is expected to lower 2026 depreciation by $45-50 million. The company generated record free cash flow of $1.4 billion in 2025 (24% margin) and authorized a massive $6 billion share repurchase program—over 20% of current market cap. Investors will scrutinize whether margin improvements can offset underutilization charges (approximately 700 basis points in Q1) and whether the buyback signals confidence or reflects limited organic growth opportunities.

Ahead of the release, analyst sentiment has improved notably, with the average recommendation rising to 3.79 from 3.67 a month ago as two additional analysts upgraded to Strong Buy. BofA Securities upgraded ON to Buy with an $85 target in April, citing AI data center traction and operational improvements, while B. Riley Financial issued a Buy rating with a $115 target, implying 29% upside. However, the consensus remains cautious, with 19 of 33 analysts maintaining Hold ratings, reflecting concerns about near-term demand visibility and valuation after the stock's 146% surge over the past year.

Part 2: Historical Earnings Performance

On Semiconductor has demonstrated a consistent pattern of exceeding analyst expectations, beating estimates in three of the past four quarters. The company delivered $0.55 in Q1 2025, surpassing the $0.51 consensus by 7.84%, followed by a narrow miss of $0.53 versus $0.54 expected in Q2. The trend resumed in Q3 with $0.63 against a $0.59 estimate (6.78% beat) and continued in Q4 with $0.64 versus $0.62 (3.23% beat).

The magnitude of beats has moderated from the 7.84% surprise in Q1 2025 to 3.23% in Q4, suggesting either improving analyst calibration or narrowing upside potential as the company navigates cyclical headwinds. The single miss in Q2 was marginal at 1.85%, indicating ON generally meets or exceeds expectations even during challenging demand environments.

Year-over-year comparisons reveal the depth of the cyclical downturn: Q1 2025's $0.55 represented a 49% decline from Q1 2024's $1.08, while Q4 2025's $0.64 was down 32% from Q4 2024's $0.95. The sequential improvement from $0.55 to $0.64 across 2025 suggests the trough has passed, though earnings remain well below prior peaks. The upcoming Q1 2026 estimate of $0.61 implies a 10.91% year-over-year recovery, marking a potential inflection point if the company can sustain momentum.

Note: These figures reflect diluted GAAP earnings per share, reported before non-recurring items, and may differ from the non-GAAP figures used by some sources.

Part 2.1: Price Behavior Around Earnings

On Semiconductor typically reports earnings after market close, meaning Day 0 reflects anticipatory trading before results are released, while Day +1 captures the market's first full reaction to the actual numbers.

Historical price behavior shows significant volatility around earnings, with Day 0 moves averaging 6.26% in absolute terms and Day +1 moves averaging 2.67%. The most dramatic reaction occurred in August 2025, when the stock plunged 15.58% on Day 0 ahead of results, followed by an additional 1.52% decline the next session—likely reflecting concerns about automotive and industrial demand that materialized in the report.

More recently, volatility has moderated. The February 2026 report saw minimal Day 0 movement (0.15% decline) but a solid 3.50% gain on Day +1 as investors digested the Q4 beat and management's constructive guidance. The November 2025 report showed a 0.76% Day 0 gain followed by a 4.32% Day +1 decline, suggesting initial optimism gave way to disappointment over forward guidance or commentary.

The average Day 0 range of 8.01% and Day +1 range of 5.38% indicate substantial intraday swings regardless of the ultimate direction. Investors should anticipate meaningful volatility, particularly given the stock's recent momentum and elevated valuation multiples. The pattern suggests the market often reacts more strongly to guidance and management commentary (Day +1) than to the initial headline numbers (Day 0).

Part 2.2: Options Market Expected Move

The options market is pricing a 9.49% expected move for the May 8 weekly expiration, significantly higher than the 6.26% average absolute Day 0 move and 2.67% average Day +1 move observed historically. This elevated implied volatility of 100.94% suggests options traders are anticipating above-average price swings, possibly reflecting uncertainty around guidance, margin trajectory, or the sustainability of AI data center growth. The $9.78 expected move implies a trading range between $93.25 and $112.80, with the upper bound representing nearly 10% upside from current levels.

Part 3: What Analysts Are Saying

Analyst sentiment on On Semiconductor has improved recently, with the average recommendation rising to 3.79 from 3.67 a month ago, reflecting a shift toward more bullish positioning. The current consensus includes 12 Strong Buys (up from 10), 2 Moderate Buys (unchanged), and 19 Holds (down from 21), with no Sell or Strong Sell ratings. This distribution indicates growing conviction among bulls while a majority still maintains a cautious stance.

The mean price target of $72.57 implies 29.5% downside from the current price of $103.03, a striking disconnect that reflects the stock's rapid 146% appreciation over the past year outpacing analyst expectations. The wide target range—from a low of $56.00 to a high of $115.00—underscores divergent views on valuation and growth prospects. The high-end target suggests some analysts see further upside if AI data center momentum accelerates and margins expand as planned, while the low-end target implies significant risk if cyclical recovery stalls or the SiC business faces commoditization pressures.

The sentiment trend is classified as "improved," driven by recent upgrades from firms like BofA Securities and B. Riley Financial, both citing operational improvements and AI infrastructure exposure. However, the fact that 19 of 33 analysts maintain Hold ratings suggests many remain on the sidelines, likely concerned about valuation after the stock's dramatic run and uncertain about the timing and magnitude of automotive and industrial recovery. The consensus appears to be waiting for sustained evidence that margin expansion and AI growth can offset cyclical headwinds before committing to more aggressive bullish calls.

Part 4: Technical Picture

On Semiconductor enters earnings with exceptionally strong technical momentum, as reflected in the Barchart Technical Opinion showing a 100% Buy signal—unchanged from last week but significantly improved from the 56% Buy reading a month ago. The stock is trading above all key moving averages, with the current price of $103.03 well above the 200-day moving average of $58.17, indicating a powerful long-term uptrend.

Timeframe Analysis:

• Short-term (100% Buy): Maximum bullish signal indicates near-term momentum is exceptionally strong, with the stock in a clear uptrend across all short-term indicators
• Medium-term (100% Buy): Sustained buy signal confirms the intermediate-term trend remains firmly positive, with no signs of consolidation or reversal
• Long-term (100% Buy): Maximum long-term buy signal reflects the stock's powerful multi-month rally and suggests the broader trend structure remains intact

Trend Characteristics: The combination of Top 1% strength and Top 1% direction indicates ON is among the strongest trending stocks in the market, with both momentum magnitude and trend quality at elite levels heading into earnings.

The stock's position above all moving averages—from the 5-day at $98.81 to the 200-day at $58.17—demonstrates consistent buying pressure across all timeframes. The widening gap between shorter and longer-term averages (the 20-day at $83.15 is 43% above the 200-day) reflects accelerating momentum, though this also increases vulnerability to a sharp reversal if results or guidance disappoint.

Key resistance may emerge near the $115.00 high analyst target, while support likely sits at the 20-day moving average of $83.15, representing a potential 19% pullback zone if sentiment sours. The technical setup is decidedly supportive heading into earnings, with all indicators aligned bullishly, but the magnitude of the recent rally and stretched valuation multiples (P/E of 326x) mean the stock has limited room for error. Any disappointment on guidance, margin trajectory, or AI revenue growth could trigger profit-taking, while a strong beat with raised outlook could propel the stock toward the $115 level. The extreme momentum suggests volatility will be elevated regardless of direction.
