ON — ON Semiconductor Corporation

The latest earnings print (Aug. 3, 2026) beat consensus on both revenue and EPS, Q3 guidance came in above prior estimates, and management said AI data-center power revenue should more than double in 2026. Buyers have responded, but the broader semiconductor sell-off has kept the price in the mid-$70s. As of 2026-08-27 sentiment is cautiously positive: fundamentally improved, technically weak.

The 3-year pattern is a classic cyclical trough-and-inflection, not a stable uptrend. Revenue fell from roughly $2.18B per quarter in late 2023 to a trough near $1.45B in Q1 2025, then stabilized and began climbing; Q2 2026 revenue of $1.604B is up 9.2% YoY from Q2 2025's $1.469B. GAAP earnings were distorted by a large Q1 2025 loss (gross margin collapsed to 20.3%, likely one-off charges) and a small Q1 2026 loss, but the underlying trend since mid-2025 is sequential improvement: Q2 2026 operating income of $258.6M and EPS of $0.56, with non-GAAP gross margin up for the fourth straight quarter to 39.3% and utilization at 83%. This is an early recovery, with revenue still below 2024 levels but margins and operating income clearly inflecting upward.

As of 2026-08-27, the headline TTM P/E of 47.3 and P/S of 4.70 look expensive, but the TTM EPS of $1.615 is depressed by trough margins and charges. On forward estimates, the picture is much more reasonable: next-FY EPS of $3.199 puts the forward P/E around 23.4x, and the TTM PEG is about 1.05. Versus ON's own 5-year averages (P/E 52.6, P/S 3.88), the stock is neutral: rich on sales, cheap on trailing earnings. Overall, valuation is fair with a modest upward bias if the margin recovery continues.

At $74.80 as of 2026-08-27, the market is paying roughly 23x next-FY EPS of $3.199. That is not a zero-growth price, but it is also not giving full credit to a durable margin recovery or AI data-center power doubling. If Q3 revenue lands in the $1.65-1.75B guided range with EPS of $0.81-0.93, annualized earnings power approaches $3.50+, which would make the current price under 22x and likely support re-rating. If the recovery stalls, the 23x forward multiple offers some cushion but not a deep-value margin of safety.

As of 2026-08-27, RSI stood at 39.15, below the 50 midpoint but not oversold. The stock was -4.6% below its 20-day SMA (~$78.4), -16.0% below its 50-day SMA (~$89.1), and -3.6% below its 200-day SMA (~$77.6). That is a short-term down-trend/large-consolidation posture after the fall from $134.92. No confirmed technical reversal yet; a close back above the 20-day and then the 50-day would improve timing, while support to watch is the $70-ish zone and then the 52-week low of $44.56.

• Sharp semiconductor sector correction since late June 2026, triggered by profit-taking, rising bond yields, and valuation concerns after a historic run.
• AI data-center power demand is a genuine tailwind: ON expects 2026 AI power revenue to more than double, with SiC power up roughly 60% YoY.
• Legacy automotive and industrial end-markets are still in inventory digestion; EV demand growth has been slower than the early cycle hype.
• Rising raw-material costs have forced a second round of pricing actions, and lead times on tight components have stretched to 32 weeks, creating both pricing power and supply-chain risk.
• High-beta (2.0) exposure means the stock is especially sensitive to interest-rate and risk-appetite swings.

• September 2026 Analyst Day: expected to lay out multi-year revenue paths for data-center power delivery and edge AI, a potential re-rating catalyst.
• Q3 2026 earnings: guided revenue of $1.65-1.75B and non-GAAP EPS of $0.81-0.93; any upward revision or margin upside would reinforce the recovery narrative.
• AI data-center power and SiC revenue growth continuing to outpace the legacy auto/industrial business.
• Closing of the Synaptics acquisition (expected mid-2027) if it expands the edge-AI/portfolio story, plus completion of $900M in non-core divestitures.

• Automotive/industrial recovery stalls or EV demand stays weak, leaving a large part of the portfolio without a cyclical tailwind.
• Synaptics acquisition adds integration risk, potential dilution, or leverage; debt already rose in Q2 2026.
• Semiconductor multiple compression continues: with beta near 2.0, ON can fall hard in a risk-off tape despite improving fundamentals.
• Competition in power semiconductors/SiC, raw-material inflation, and execution risk on the Treo/GaN platform ramp.

ON is a good risk/reward at $74.80 for a tolerant investor: the cyclical trough appears to be behind it, margins are inflecting up, the balance sheet is strong (current ratio around 3.5, net debt modest), and AI power gives it a growth kicker beyond the legacy auto cycle. The stock is not in a confirmed technical uptrend and is high-beta, so entry sizing and dollar-cost averaging matter more than for a low-volatility name.

I applied a 28x forward P/E multiple to next-FY estimated EPS of $3.199, a level justified by ON's improving gross/operating margins, strong balance sheet, and AI data-center growth premium, while remaining below the stock's own 5-year average P/E of 52.6 and the analyst consensus target of $104.67. This produces a fair value of $89.57, or roughly 20% above the 2026-08-27 price.
