1,298 material Form 8-K filings that 1,057 companies we cover made with the SEC in April 2026, each read and summarized by AI: what happened, the key figures, whether it reads positive or negative for shareholders, and how big a deal it is (impact 1-5).

On April 16, 2026, CrowdStrike's board approved a performance-based equity award to President Michael Sentonas with a target of 100,000 performance stock units (PSUs). The number of shares he can receive depends on the company's three-year total stockholder return relative to S&P 500 companies, ranging from zero to 200,000 shares, so the award's value to shareholders depends on future stock performance.
Target award is 100,000 PSUs, with payouts from 0% to 200% of target based on relative total stockholder return.
Performance period runs from December 22, 2025 to December 22, 2028; earned PSUs vest 25% each on March 20, June 20, September 20 and December 20, 2029.
Payout is 50% of target at the 25th percentile and 200% at the 90th percentile or above; below the 25th percentile pays nothing.
The company cites fiscal 2026 revenue of $4.81 billion and ending ARR of $5.25 billion, and a long-term ambition of $20 billion in ending ARR.
