Open-market buys and sells only — the deliberate trades. Zero here doesn’t mean no filings: grants, option exercises and tax withholding (below) are compensation, not market trades.

Fiscal period ending 2025-12-31 versus 2024-12-31 — view filing on EDGAR →
A $3.7 billion impairment charge — the first in recent years — is the dominant new risk, compounded by fresh disclosures on AI-driven grid strain, tariff/trade policy exposure, wildlife regulatory restrictions, and key-person concentration. These worsening factors are partially offset by a substantial cleanup of Endeavor Acquisition-era debt, governance, and liquidity risks, which appear largely resolved through repayment, refinancing, or integration completion, though new indebtedness disclosures signal the balance sheet remains leveraged.
