Caught in somewhat of a catch-22, shares of Excite@home are trading down nearly 50 percent this morning. A Merrill Lynch report stated that the company risks being delisted from the Nasdaq since its share price is below a dollar. The delisting, the report says, would cost Excite@home nearly US$100 million, effectively wiping out the company’s cash reserves and force bankruptcy. Shares are currently trading at 50 cents. Excite@home is the largest provider of cable Internet access in the US.
