This is a routine insider monetization via option exercise, not a distress signal. The sale is moderate in size relative to the insider's total position and the company's $6.2B market cap. Monitor for actual Form 4 filings to confirm execution. No immediate trading action warranted.

Executive Summary
Christopher Peetz, an officer and director of Mirum Pharmaceuticals, filed a Form 144 notice of intent to sell 30,000 shares of common stock, with an approximate market value of $2.88 million based on the filing date. The shares were acquired via stock option exercise on the same day, suggesting a cashless exercise-and-sell transaction. While the sale is modest relative to Peetz's remaining holdings (40,985 shares worth ~$3.77 million as of March 2026), the filing signals insider intent to monetize equity ahead of any potential catalyst.
