Quantum's stock price had languished below $1 per share since September 2015 and the company faced the prospect of being delisted from the New York Stock Exchange. So on April 3 Quantum announced a 1-for-8 reverse stock split effective at the close of trading on April 18 with common stock trading on the split-adjusted basis on April 19. The number of outstanding shares dropped from approximately 273 million shares to 34 million shares.

Quantum's stock closed at $0.83 per share on Dec. 30, 2016. That price has been adjusted to reflect the reverse stock split for the purpose of this analysis.

In March Quantum signed an agreement with VIEX Capital Advisors, which owns approximately 11 percent of Quantum's outstanding shares, to reconstitute the company's board of directors with a majority of new, independent directors over a period of several months.

For its fiscal 2017 (ended March 31,) Quantum reported revenue of $505.3 million, up 6 percent from $476.0 million in fiscal 2016. More importantly, the company reported net income of $3.6 million for the year compared with a $76.4 million loss in fiscal 2016.
