Sycamore (SCMR) received a delisting notice from the Nasdaq for missing its annual report filing deadline.
The Chelmsford, Mass., networking equipment maker says it is appealing the Nasdaq's decision, but the company did not specify when it would have its delinquent financial reports ready.
Sycamore is among dozens of companies reviewing stock option grant practices. The company is investigating whether there were discrepancies in its grant dates and how much, if anything, making the appropriate adjustments will cost.
Sycamore shares rose a penny to $3.94 Monday in after-hours trading.
