Key points
- Micron (MU) CEO Sanjay Mehrotra sold 40,000 shares on July 24 for $37.3 million.
- It is his fourth sale of exactly 40,000 shares, each 28 days apart since May 1.
- The 10b5-1 plan behind them was signed January 30, months before MU peaked at $1,255.
- He kept 304,503 shares outright and 607,075 more in family trusts.
Two Form 4s arrived at the SEC on July 28 from Micron (MU) chief executive Sanjay Mehrotra. Both cover the same trading day, July 24, and together they report 40,000 shares sold for $37,290,091. There are two filings instead of one for a dull reason, which the second one states outright: "Due to a 30 line-item limitation in Table 1, this is the second of two Forms 4 filed by the Reporting Person."
The checkbox that matters is marked on both. These sales ran on a Rule 10b5-1 plan, and a footnote dates that plan to January 30, 2026. A 10b5-1 plan is an instruction an executive signs in advance. It tells a broker what to sell and when, and once it's running the executive doesn't get to pick the days.
The share count is what made me go back and pull the earlier filings.
| Sale date | Shares | Proceeds | MU close that day |
|---|---|---|---|
| May 1, 2026 | 40,000 | $21.5 million | $542.21 |
| May 29, 2026 | 40,000 | $38.5 million | $971.00 |
| June 26, 2026 | 40,000 | $46.3 million | $1,132.33 |
| July 24, 2026 | 40,000 | $37.3 million | $920.95 |
Four sales, four identical share counts, and proceeds that differ by nearly $25 million between the smallest and the largest. A fixed-share plan works that way by design. The January instruction set a quantity, and Micron's price on each of those four dates settled everything else.
The 28-day clock
May 1, May 29, June 26, July 24. Each of those is exactly 28 days after the one before it. The plan is running on a four-week timer.
The plan's start date lines up just as neatly. Rule 10b5-1 makes officers and directors wait at least 90 days after signing a plan before it can sell anything, so nobody can sign on a Monday and sell on the Tuesday with news in their pocket. Mehrotra signed on January 30. Ninety days later is April 30. The first sale landed May 1.
If the timer holds, the next 40,000 shares go out around August 21.
What he still owns
The last line of the second filing puts him at 304,503 shares held directly. A separate line reports 607,075 more sitting in grantor retained annuity trusts, which a footnote describes as being for him and his family. The 40,000 shares he sold in July came out of a stake still above 900,000 shares. His 2026 sales now add up to $143.5 million across those four dates, all of it through the January plan.
What this does not tell you
Micron closed at $820.53 on July 28 and was near $784 late Wednesday morning. Mehrotra's July shares went out at an average of $932.25. Put those two numbers side by side and you can build a story about a chief executive who got out near the top. It would be the wrong story. The same plan sold 40,000 shares at an average of $1,158 in June, and 40,000 at $536 back on May 1, when Micron was worth less than half what it fetched eight weeks later.
Compare it with the filing our insider tracker picked up a few days earlier, when Micron's chief accounting officer sold 879 shares at exactly $1,000 with the 10b5-1 box left empty. Somebody picked the day on that one. This one got picked in January. If you want the mechanics of how these plans work, and the places they can still be gamed, we went through that separately.
The next thing to watch for is the August tranche, due around the 21st if the spacing holds. New Micron filings land on the Micron page as they arrive.
