Do companies that cancel their shares get counted as a total loss in backtests?

Ive been working with P123 and I noticed something, recently a company’s shares got cancelled (LKSDQ) however when looking at results for the backtest, the shares despite being a 100% loss quite literally showed very little change over the time period that they got cancelled.

Does anyone know how to deal with this when analyzing backtest results? Am I mistaken?

When the shares of a company get delisted, P123 backtests simulate the sell at the last known price, which seems rather realistic to me.

You can’t sell a share at its last known price if it’s cancelled

As far as I can tell, LSC Communications was sold to Atlas Holdings, a private equity firm, who bought out the shareholders earlier this month. But I could be wrong. What information do you have about this? Did the remaining shareholders see their shares simply disappear on March 11? Or did they get $0.02 for them?
