Form 4 filing for Century Aluminum Co. (CENX) dated 07/02/2025 discloses a single reportable transaction by the Glencore group, which is a >10% beneficial owner of the issuer.
- Transaction date: 06/30/2025
- Security: Series A Convertible Preferred Stock converted into common stock.
- Amount converted: 164.77 preferred shares, automatically exchangeable on a 1-for-100 basis into 16,477 CENX common shares.
- Resulting ownership: Glencore reports 12,554,508 common shares held indirectly through its subsidiary Glencore AG after the conversion.
- A separate line in Table I references 27,500,000 common shares marked as “D” (disposed), but no execution date or price is provided in the filing excerpt; therefore the timing and nature of that figure cannot be confirmed from the supplied text.
The filing clarifies that Glencore AG directly owns the converted securities, while Glencore International AG and Glencore plc are indirect beneficial owners. No sale proceeds, option exercises, or additional derivative activity are reported.
Materiality assessment: The conversion adds a de minimis 16.5 k shares to Glencore’s existing 12.55 m-share position, implying an immaterial percentage change in its ownership stake. Without details on the 27.5 m-share “D” line, the net ownership change appears modest and the filing is judged informational rather than market-moving.
Century Aluminum (CENX) – Form 4 insider filing
Director Errol Glasser reported the annual equity award granted on 16 Jun 2025. The filing shows an acquisition (code “A”) of 7,778 restricted stock units (RSUs) at a price of $0, reflecting standard non-cash director compensation. All RSUs vested immediately on the grant date.
Following the transaction, Mr. Glasser’s direct beneficial ownership increases to 118,697 common shares. The total includes shares issuable from previously vested RSUs that have been deferred under an earlier election. No open-market purchases, sales, derivative positions, or additional insider activity were disclosed.
The event is routine and does not alter the company’s capital structure, but it modestly aligns director interests with shareholders by expanding equity exposure.
Credo Technology Group Holding Ltd (NASDAQ: CRDO) has received a Form 144 filing indicating a planned disposition of 80,000 common shares.
Key details are as follows:
- Filer/Account holder: Walden Technology Ventures II LP (address in Grand Cayman).
- Broker: Morgan Stanley Smith Barney LLC, Executive Financial Services, New York, NY.
- Class: Common stock.
- Approximate sale date: 24 Jun 2025, on the NASDAQ exchange.
- Aggregate market value of planned sale: US$7,261,816, implying an indicative price of about US$90.77 per share.
- Shares outstanding: 169,801,216, so the planned sale equals roughly 0.05 % of CRDO’s total shares.
The filing also discloses that the shares were originally acquired directly from the issuer on 8 Dec 2017 (58,770 shares) and 22 Dec 2020 (21,230 shares) for cash consideration.
Recent trading activity: Over the last three months Walden Technology Ventures II LP has already sold 404,297 CRDO shares in five transactions, generating cumulative gross proceeds of roughly US$31.5 million. The largest single sale was 171,473 shares on 16 Jun 2025.
Because Rule 144 notices are intent to sell filings, the shares may or may not ultimately be sold, and no pricing information beyond the aggregate value is provided. The proposed volume is small relative to CRDO’s float, suggesting limited direct market impact, but continuing distributions by a venture-capital holder may be noteworthy to investors monitoring insider supply dynamics.
Century Aluminum Co. (CENX) – Form 4 filing (18 Jun 2025)
Director Andrew G. Michelmore reported an annual grant of 7,778 restricted stock units (RSUs) that fully vested on 16 Jun 2025. Because the RSUs vest immediately, they converted into common shares at no cost to the director. To cover tax withholding, 2,333 shares were automatically sold/withheld at $17.36 per share.
After both entries, Michelmore’s direct holdings increased to 89,089 common shares, a net addition of 5,445 shares (approximately 6% growth versus his pre-grant position). No derivative securities were involved, and the filing was made on behalf of the director by attorney-in-fact Paul Sharobeem.
The activity reflects routine board compensation rather than an open-market purchase, but it modestly lifts insider ownership.
Century Aluminum Co. (CENX) filed a Form 4 showing that director Jennifer Mary Bush received an annual equity award on 06/16/2025. The grant consists of 7,778 restricted stock units (RSUs) issued at no cost. Following the award, Bush’s direct beneficial ownership rose to 46,872 common shares. The RSUs vest in full on the earlier of (i) the 12-month anniversary of the grant date, (ii) the company’s next regular annual shareholder meeting, or (iii) certain other events stipulated in the award agreement. No derivative securities were involved and no shares were sold. The filing, signed on 06/18/2025, reflects routine board compensation and does not represent an open-market transaction.
Century Aluminum Co (CENX) – Form 4 insider filing
Director Jarl Berntzen received an annual equity grant of 7,778 restricted stock units (RSUs) on 16-Jun-2025. The award was granted at $0 cost as part of the company’s non-employee director compensation program. All RSUs will vest in full within 12 months, at the next annual meeting, or upon certain accelerated-vesting events. Following the grant, Berntzen’s direct beneficial ownership rises to 208,951 CENX shares, which includes previously vested RSUs that he has elected to defer.
No open-market purchases or sales occurred; the filing merely reports the receipt of equity compensation. The transaction modestly increases insider equity alignment but does not signal a change in fundamental outlook or corporate strategy.
