Section 16 filings recorded for owner CIK 0001910424. An owner CIK is not a stable person identifier — one person can hold several — so this page profiles the CIK exactly as filed. Superseded originals are excluded; an amendment restates its whole form.
Performance metrics require licensed market data.
Open-market transactions over time
One mark per reported purchase or sale, placed on its transaction date. Purchases sit above the zero line and sales below it, and the area of each mark is proportional to shares × the reported price. Grants, option exercises, tax withholding and gifts are excluded — they say nothing about what this filer believed.
