Why it matters
OptimistFi's case is that REX works if disciplined plant operations and commodity-spread management keep turning volatile ethanol markets into cash rather than a temporary margin cycle. This filing does not change that view. It shows a trim, not a shift in the business, and Rose still held 2,278,324 shares. The 50,000 shares were about 2.1% of his pre-trade holding, according to OptimistFi's calculation.
That makes the sale a modest reduction, not a full exit. The remaining stake is still large. The filing is centered on a partial sale, not a broader corporate announcement. Rose still held 2,278,324 shares after the trade, so the filing reads as a position update.
The trade price mainly helps size the sale. The filing reports a weighted average $42.55 a share, and the sale was spread across several trades, not one block. The counterpoint is that this is still only one insider transaction and it leaves Rose with a very large remaining stake. Investors will compare that with the next filing.

What's next
The next Form 4 will be the next dated check on insider activity. A later sale would support the idea of a continuing trim. No further sales would leave this brief unchanged. Until then, the main takeaway is that Rose remains a large holder after the reported sale. The filing was filed on 2026-10-01.
