James Lawrence Dolan, serving as Executive Chairman and CEO across a portfolio of media and entertainment companies, has maintained an active presence in SEC Form 4 filings, with 67 total transactions spanning four issuers. The aggregate figures reveal a clear net-selling posture: open-market purchases totaled approximately $10.7 million, while open-market sales reached roughly $26.6 million. However, the most recent filings—dating from September 2025 through June 2026—show no open-market buys or sells, with activity instead dominated by automatic and mechanical events such as option exercises (code M), tax-withholding share surrenders (code F), and sales back to the issuer (code D).
The bulk of recent activity centers on Sphere Entertainment Co. (SPHR), where a cluster of filings on February 17, 2026, involved option exercises valued at $3.66 million, paired with tax-withholding dispositions of $7.31 million and $2.49 million, alongside two issuer buybacks totaling $2.66 million. This pattern—exercising options and immediately surrendering shares to cover tax liabilities—is characteristic of routine compensation management rather than discretionary trading. Similar mechanics appeared on September 15, 2025, across SPHR, Madison Square Garden Sports Corp. (MSGS), and Madison Square Garden Entertainment Corp. (MSGE), with tax-related sales of $1.84 million, $2.92 million, $2.10 million, $2.38 million, and $2.45 million, all tied to option exercises valued at zero.
The most recent entries are non-monetary: a compensation grant (code A) for AMC Networks Inc. (AMCX) on June 16, 2026, and zero-value code J transactions (likely in-kind conversions or adjustments) for MSGS and AMCX in early September 2025. Notably, Dolan’s only open-market purchases—the $10.7 million total—are not reflected in the recent window, suggesting his discretionary buying occurred earlier in the filing history. The absence of recent P or S codes, combined with the mechanical nature of the latest filings, indicates a period of passive position management rather than active conviction trading.
