Sprott Junior Uranium Miners ETF (URNJ US) – Portfolio Construction Methodology

The underlying Nasdaq Sprott Junior Uranium Miners Index targets mid-, small-, and micro-cap issuers whose primary businesses are uranium production, development, exploration, or royalty interests; each issuer must have a Uranium Intensity Score ≥50% of revenue. Eligible securities are common shares or depositary receipts, one line per issuer, listed on specified major exchanges, and seasoned for three full calendar months before the June/December reviews. New entrants must have free-float market cap USD 30m–3bn; existing members must be ≥USD 25m and ≤USD 5bn. The index selects all eligible names and applies modified free-float market-cap weighting with caps: 12% per constituent, 4.75% for names outside the top four by float cap, and a 0.3% minimum weight. Reconstitution and rebalance occur semi-annually, effective the first trading day after the third Friday of June and December.
