FAQ

What insider transactions did SSR Mining (SSRM) EVP William K. MacNevin report?

William K. MacNevin reported two routine, non-market dispositions. He surrendered 32,022 Performance Share Units to the issuer for cash and had 2,617 common shares withheld to satisfy tax obligations on restricted stock unit vesting, leaving him with 254,111 directly held common shares.

Were SSR Mining (SSRM) shares sold on the open market in this Form 4?

No open-market sales were reported. The filing shows a disposition of 32,022 Performance Share Units to the issuer for cash and 2,617 common shares withheld to cover tax liabilities from restricted stock unit vesting, both standard equity award and tax-settlement mechanisms.

How many SSR Mining (SSRM) shares does William K. MacNevin hold after these transactions?

Following the reported transactions, William K. MacNevin directly holds 254,111 common shares. This figure reflects his position after 2,617 shares were withheld to cover tax obligations tied to restricted stock unit vesting, and after the separate cash-settled Performance Share Unit disposition.

What is the significance of the 2,617 SSR Mining (SSRM) shares withheld at $28.84?

The 2,617 common shares withheld at $28.84 per share were used to satisfy tax withholding obligations on vesting restricted stock units. This is classified as a tax-withholding disposition, not an open-market sale, and is a standard administrative feature of equity compensation.

What happened to the 32,022 Performance Share Units reported for SSR Mining (SSRM)?

The 32,022 Performance Share Units were redeemed for a cash payment upon completion of their performance period, in line with the governing plan. This disposition to the issuer eliminated the derivative position tied to an equal number of underlying common shares for MacNevin.

Does this SSR Mining (SSRM) Form 4 indicate any remaining derivative awards for MacNevin?

The derivative section associated with this filing shows no remaining derivative positions after the 32,022 Performance Share Units were redeemed for cash. The transactions reported therefore close out that particular performance-based award linked to SSR Mining common shares.
