Minor note, if of interest: the above enterprise value ($771 million at 1.38/sh) treats SLR's $323 million of available tax write-offs as a $97 million asset.
The $97 million is from using SLR's 0.3x multiplier for the value of expending write-offs, in their 2021 financial statement.
Without the $97 million, SLR's enterprise value is $868 million, and the EV/annual AISC margin ratio is 3.93.
