If I remember correctly, the original Office Max out of the Cleveland area rejected a fantastic offer from Staples. SPLS offered something like 16 or 17 a share. OMX was about 10/share at the time. The CEO and the BOD said "no" to the handsome offer. SPLS did not come back with a richer offer. There were many ticked off shareholders. OMX never did see the share value that SPLS had offered.
Hopefully the powers to be at ARG will be reasonable.
That OMX historical graph you may have looked at reflects the price history of the company that acquired Office Max, not the original OMX. The original OMX was picked up for peanuts. The acquiring company decided to switch over to the Office Max name years later. I wish I could remember the name of the acquiring company. Sorry.
