MERIT MED SYS INC MMSI

Company in South Jordan, 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 ($8.3m this quarter). Holder counts are more reliable. Shares outstanding: 57.6m as of 2023-07-26, 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 ≈ $83.62. Options: 4 managers hold calls ($1.1m notional), 1 hold puts ($0).
