What happened

Randolph Altschuler, a director of Xometry, Inc. (NASDAQ: XMTR), reported sales of 10,000 Class A shares on Nov. 5 for about $1.09 million.

The shares are held by Altschuler's spouse. They were sold automatically under a Rule 10b5-1 trading plan that the spouse adopted at least 90 days before the trading date, according to the Form 4.

The sales ran in eight blocks at weighted average prices from $104.79 to $113.45 per share. The largest block was 2,358 shares at $109.74.

After the sales, the spouse's holding stood at 531,270 Class A shares. Altschuler separately lists 423,029 Class A shares and 1,475,311 Class B shares held directly, plus Class A shares in four family trusts. The Form 4 was signed Nov. 6.

Why it matters

By OptimistFi's calculation, the sale was 1.8% of the 541,270 shares the spouse held before the trades. That is a small slice of one account within Altschuler's wider family holdings. The Form 4 reports the spouse-held shares as indirect ownership.

The plan is the main caveat for anyone reading the sale as a signal. The Form 4 checks the box showing the trades were meant to satisfy the Rule 10b5-1(c) affirmative defense. It says the shares were sold automatically under a plan adopted in advance, so the sale may reflect a schedule rather than a fresh view of Xometry.

OptimistFi has argued that Xometry's marketplace, supplier network and embedded services can build a higher-margin platform with improving cash generation. A small plan-based sale by a director's spouse does not test that view, so the case is unchanged.

What's next

The next test is Xometry's next quarterly report, which will update the cash generation and profitability that OptimistFi's case rests on.

Another Form 4 would be the next read on insider activity. Sales from the direct or trust holdings, or trades made outside a plan, would carry more weight than this one.
