[Form 4] Celanese Corporation Insider Trading Activity

Rhea-AI Filing Summary

Celanese Corporation director Timothy Go was credited on 08/11/2025 with phantom stock units under the company’s 2008 Deferred Compensation Plan. Each phantom unit represents the right to receive one share of Celanese common stock, and the reported units are dividend equivalents that become payable in shares following the termination of the reporting person’s service. The Form 4 shows an allocation of 0.71 phantom shares at an indicated value of $47.42, bringing total reported phantom holdings to 1,114.71 units, reported as direct ownership. The entry is recorded in Table II as a derivative securities acquisition and reflects non-cash, deferred compensation rather than an open-market trade.

Positive

• Phantom units represent one-for-one equity rights, with each phantom stock unit corresponding to one share of Celanese common stock.
• Reported holdings increased to 1,114.71 phantom units, providing a clear, auditable record of the director’s deferred compensation position.

Negative

• Units are payable only after termination of service, so there is no immediate liquidity or transfer of common shares.
• The transaction is non-cash deferred compensation and does not reflect an open-market purchase that would signal current buying interest.

Insights

Financial Analyst

TL;DR: Routine director deferred-comp allocation; no open-market purchase or sale noted.

The Form 4 documents a derivative allocation (phantom stock) credited to director Timothy Go on 08/11/2025. The units are dividend equivalents under the 2008 Deferred Compensation Plan, priced in the record at $47.42, and the filing reports total phantom holdings of 1,114.71 units. For investors, this is a compensation accounting entry that increases potential future share issuance but does not represent immediate dilution from an open-market transaction.

Corporate Governance Expert

TL;DR: Compensation-related phantom shares awarded; payout contingent on departure from service.

The disclosure clarifies that each phantom stock unit equals one share and that the reported units are dividend equivalents payable in shares upon termination of service. The filing records an acquisition (A) of derivative units and reports ownership as direct. This is a standard deferred-compensation mechanism for non-employee directors and is transparent in its payout conditions.
