Investor-owned utility based in Las Vegas, Nevada, United States
* Summed across managers. Shares that two managers' reports both contain – a subsidiary's holdings that its parent's report includes too, or a sub-adviser's in its client's – are counted once ($1.6m this quarter). Holder counts are more reliable. Shares outstanding: 71.7m as of 2024-04-26, from the company's own SEC filing; the percentage can still exceed 100%: lent-out shares are counted by the lender and the buyer, and some reports overlap without saying so. Implied quarter-end price ≈ $76.12. Options: 3 managers hold calls ($1.3m notional), 3 hold puts ($182.7k).
