AT A GLANCE

Q3 2026 earnings recap

Monolithic Power beat earnings forecasts as demand for AI and server power chips lifted sales above $1 billion and supported another increase in quarterly revenue ahead.

  • Adjusted profit per share of $8.19 beat the $7.79 forecast, while revenue of $1.2 billion exceeded the $1.16 billion estimate.
  • Enterprise data sales rose 165% from a year earlier to $507 million, showing how demand for AI and server power systems is reshaping the business.
  • The new fourth-quarter sales outlook of $1.32–1.385 billion implies about 12% growth from the third quarter at its midpoint.
  • Adjusted operating margin rose to 38.6% from 37.5%, but reported operating margin fell to 29.7% as employee share compensation increased.
  • Operating cash flow of $290 million trailed adjusted net profit of $403 million, making cash collection and inventory management important tests of growth quality.
  • At the $1,198.81 regular close, the stock traded near 66 times trailing reported profit, with recent resistance around $1,220–1,230.

The next test is delivering the stronger sales outlook while expanding supply capacity and managing export restrictions, customer concentration and semiconductor demand swings.

Explore industries

Open an industry for its comparison, valuation and companies.

U.S.-listed companies from the app’s catalog. Medians use saved positive P/E values; coverage and snapshot dates vary.

How this comparison works

Uses the saved companies from the same industry and listing market, including MPWR, ordered by cached market cap. Company snapshots can have different dates; the web cache may cover fewer metrics and periods than the app.

Periods end at each company’s dated price snapshot. Change compares the latest saved observation with one at or before the selected period’s start. A daily price change uses consecutive saved sessions. Financial data updates quarterly, so short periods may show no change. Missing history and zero starting values are excluded; a negative starting value uses its absolute value as the denominator.

Metrics use saved ratios and percentages. Market caps use the listing market’s reporting currency; underlying financial statements may use different currencies. Circle sizes have a minimum for touch visibility, and an outlined circle indicates a missing market cap. These comparisons describe data, not recommendations or price predictions.
