Why it matters
OptimistFi's case is that Micron creates durable value through disciplined capital spending and strong cash generation across memory cycles. This filing is mixed because it shows a pre-arranged insider sale. The 6,288 shares were about 10.0% of the 62,576 shares Ray held before the trade. The same filing also shows 4,298 shares acquired on 2026-10-13 and 5,954 and 3,035 shares disposed of for withholding, so the report mixes selling with compensation-related activity.
Ray still held 56,288 shares after the sale, so this was a trim, not an exit. The filing itself gives the main caveat. The sale was made under a Rule 10b5-1 trading plan. It also says Performance Restricted Stock Units awarded on October 13, 2024 remain subject to vesting until certification of performance goals at the end of year 3 of the performance period.
The filing says the goals tied to Data Center SSD and HBM3E+ were certified at 233% of target. It also says relative total shareholder return was certified at 150% of target.

What's next
Performance Restricted Stock Units awarded on October 13, 2024 still need final vesting certification at the end of year 3 of the performance period. The awards have a 200% aggregate limit on total target shares, so that later certification will set the final share count.
The filing says this is the first of two Forms 4 because of the 30 line-item limit. So the disclosure is split across filings. That certification is the next check for investors in this case.
