[Form 4] PDF Solutions Inc Insider Trading Activity

Rhea-AI Filing Summary

Leidos Holdings, Inc. (LDOS) – Form 4 insider transaction

Chief Financial Officer Christopher R. Cage reported one transaction dated 06/30/2025.

• Acquisition: 64.1944 shares of common stock credited at $0.00 per share. The shares represent dividend-equivalent rights that were automatically reinvested in the company’s Key Executive Stock Deferral Plan.
• Post-transaction ownership: 29,288.682 indirect shares held via the deferral plan and 46,953 direct shares.

No derivative securities were involved and no sales were disclosed. The filing does not indicate any open-market purchases or dispositions; the recorded activity is routine and non-cash. Given the immaterial share amount relative to the executive’s existing holdings, the filing is unlikely to have a meaningful impact on LDOS’s share count or market perception.

Positive

• CFO increased indirect holdings, albeit by only 64 shares, which marginally aligns executive incentives with shareholders.

Negative

• Transaction size is immaterial (≈0.0001% of shares outstanding) and provides no actionable insight into management’s outlook.

Insights

Securities Analyst

TL;DR: Routine dividend-equivalent share accrual; negligible market impact.

The CFO’s acquisition of 64 shares at no cost is a standard bookkeeping entry tied to deferred compensation. After the credit, his indirect holdings total roughly 29.3k shares, while direct ownership remains 46.9k shares. There is no evidence of discretionary buying or selling, and the transaction neither signals bullish nor bearish sentiment. Investors can treat the filing as administratively neutral.
