SHIMMICK CORPORATION SEC Filings

Form 144 highlights for Shimmick Corporation (SHIM)

The filing discloses a proposed sale of 916 common shares (aggregate market value $1,567.28) through TD Securities on or about June 27, 2025. The seller, Mitchell B. Goldsteen, is an affiliate of the company; the form does not state his exact role but lists his Irvine, CA business address. Total outstanding shares are 34,361,459, so the proposed sale equals roughly 0.003 % of outstanding stock.

The filing also details Goldsteen’s trading activity over the prior three months. Between March 27 and June 26, 2025, he sold ≈170,733 shares for total gross proceeds of roughly $300,000 (sum of line-item proceeds), equal to about 0.50 % of shares outstanding. Individual daily sales ranged from 500–13,386 shares, executed almost every trading day, indicating a systematic divestment pattern.

No new financial, operational or strategic information about Shimmick is provided; Form 144 is strictly a notice of intent to sell. Goldsteen certifies that he is not in possession of undisclosed material adverse information and, if relying on Rule 10b5-1, that the plan was adopted in good faith. The filing is categorized as LIVE.

Investor takeaway: The notice itself covers a very small additional sale, but it confirms ongoing insider selling activity. While the absolute percentage is minor, investors often monitor insider trends for sentiment signals. No direct impact on EPS, liquidity, or corporate strategy can be inferred from this document alone.

Shimmick Corporation (SHIM) Form 4 filing: Director and 10% owner Mitchell B. Goldsteen disclosed two small open-market sales executed under a pre-arranged Rule 10b5-1 plan adopted 20 Aug 2024.

• 26 Jun 2025: sold 7,122 common shares at a weighted-average price of $1.69.
• 27 Jun 2025: sold 916 common shares at a weighted-average price of $1.71.

Total shares sold: 8,038. Following the transactions, Goldsteen—through his wholly owned GOHO, LLC—continues to hold 21,384,776 shares of Shimmick common stock. Ownership remains indirect (I); the filer disclaims beneficial ownership beyond his pecuniary interest.

The sales represent less than 0.04 % of Goldsteen’s post-transaction stake and therefore appear immaterial to the overall ownership structure. No derivative transactions were reported.

The Form 144 filed on 26 June 2025 notifies the SEC of a planned insider sale by Mitchell B. Goldsteen, an affiliate of Shimmick Corporation (NASDAQ: SHIM). The notice covers the prospective disposition of 7,122 common shares through TD Securities (USA) LLC at an aggregate market value of $12,040.45. Given the company’s 34,361,459 shares outstanding, the planned sale equals roughly 0.02 % of the float, indicating limited dilution or ownership impact.

The shares were originally acquired on 09 December 2020 in a private transaction with GOHO LLC, when Goldsteen obtained 21.91 million shares. The insider certified that he possesses no non-public adverse information and is acting under a Rule 10b5-1 trading plan adopted on 20 August 2024.

The filing also discloses a history of frequent open-market sales between 26 March and 25 June 2025. These transactions involve dozens of small blocks that collectively amount to tens of thousands of shares and generate cumulative proceeds of approximately $280 k (based on line-item totals). None of the individual sales exceed Rule 144 thresholds, but the pattern reflects ongoing liquidity activity by the insider.

From an investment perspective, the notice signals continued but modest insider selling rather than a material change in ownership structure. Investors may wish to track additional Form 144 or Form 4 filings to determine whether the cadence or size of sales accelerates, which could carry stronger valuation implications.
