Insights

Corporate Governance Expert

TL;DR: Routine executive deferred-compensation election; no cash proceeds and no change in voting economic exposure noted in the filing.

The report documents an administrative conversion of vested RSUs to phantom stock under the companys deferred compensation plan rather than a sale. This is typically a non-cash, election-driven transaction that preserves a deferred economic interest payable on separation. The filing identifies indirect ownership through multiple trusts and an IRA, which is standard for estate and wealth-planning structures and does not by itself indicate a change in control or a liquidity event.

Securities/Filing Compliance Analyst

TL;DR: Form 4 properly discloses a zero-price disposition tied to a deferral; reporting appears complete for the listed positions.

The Form 4 discloses the disposition code and explanatory footnotes including the swap of vested RSUs for phantom stock and the payment terms (lump sum upon separation). The signature by an attorney-in-fact is provided. All classes and amounts listed in Table I and II reconcile to the explanation. There are no indications of additional derivative exercises, cash sales, or market transactions in this filing.

Explanation of Responses:

1. In connection with the vesting on August 20, 2025, of Restricted Stock Units ("RSUs") previously granted to the Reporting Person, the Reporting Person's receipt of 1,125 shares of Class A Common Stock was deferred, resulting in the Reporting Person's receipt instead of 1,125 shares of phantom stock pursuant to the Issuer's deferred compensation plan. The Reporting Person is therefore reporting the disposition of 1,125 shares of Class A Common Stock in exchange for an equal number of shares of phantom stock.

2. A portion of these securities are RSUs. Each RSU represents a contingent right to receive one share of the Issuer's Class A Common Stock.

3. These shares are held of record by the Greg and Christina Baszucki Living Trust dtd 08/18/2006 of which the Reporting Person serves as trustee. The Reporting Person may be deemed to have beneficial ownership of the shares held by the Trust.

4. These shares are held directly by the Morningstar Dynasty Trust dtd 11/13/2020 of which Bessemer Trust Company of DE, N.A. serves as trustee. The Reporting Person may be deemed to have beneficial ownership of the shares held by the Trust.

5. These shares are held directly by the Crossbow Dynasty Trust dtd 11/13/2020 of which Bessemer Trust Company of DE, N.A. serves as trustee. The Reporting Person may be deemed to have beneficial ownership of the shares held by the Trust.

6. These shares are held directly under a Roth IRA account for the Reporting Person (formerly known as the PENSCO Trust Co).

7. Each share of phantom stock represents a right to receive one share of Class A Common Stock.
