When does Monolithic Power Systems, Inc. (MPWR) report earnings? On Oct 29, 2026, after the close
Of its last 12 earnings announcements: 10 after the close (and 2 with no time on the filing). Each one comes from the 8-K with item 2.02 that Monolithic Power Systems filed with the SEC, paired with the 10-Q or 10-K for that same quarter: 61 quarters since Aug 2, 2011, and every row links to its filing.
Next announced date: Oct 29, 2026, after the close. It comes from the company through the public Nasdaq calendar, not from the SEC: it is a scheduled date and companies do move it. Everything else on this page already happened, with its filing attached.

Where each number comes from
From the 8-K with item 2.02 ("Results of Operations and Financial Condition") that Monolithic Power Systems filed on EDGAR, the SEC's public database; only those with their 10-Q or 10-K behind them count, so other 8-Ks with the same item (production figures, monthly sales) stay out. The time is converted to New York time using this specific company's stamp convention (its EDGAR stamp arrives in UTC), and it is not assumed: it is derived from the hours in which EDGAR accepts filings.
What this data does not know
- The exact time of the press release: the 8-K reaches EDGAR minutes or hours later, so Monolithic Power Systems's median 16:01 is an upper bound. The session says which one the news landed in, not what minute it was said.
- Nothing before Aug 2, 2011: it is Monolithic Power Systems's oldest quarter with announcement and report paired in the file.
- What will happen. The page's only future date, Oct 29, 2026, was announced by Monolithic Power Systems on the Nasdaq calendar and can be moved. Monolithic Power Systems reporting after the close 2 quarters in a row does not say the next one will be the same.
- Monolithic Power Systems's identity is its SEC CIK (0001280452), not its symbol: symbols get recycled and renamed.

What is behind these dates
The concepts on this page, explained from scratch in the Academy. Free, no account.
- Guessing next quarter's earnings gives no edgeWhy knowing a quarter's earnings in advance is not enough to make money: what moves the price is the gap against what was expected.
- Supply, demand and price: why it rises and falls constantlyWhat happens to the price on announcement day, and why excellent results can leave the stock falling.
- The three financial statements of a companyWhat is inside the 10-Q and the 10-K whose lag behind the announcement this page measures.
- Point-in-time data and look-ahead biasWhy the date a figure became public matters as much as the figure, which is exactly the distinction behind the two date columns above.
