Shares of Black Box(BBOX Quote) were among technology's losers Friday, tumbling 19% after the computer-networking equipment company posted disappointing fourth-quarter results and said it recently discovered accounting irregularities in its Italian operations.

For the period ended March 31, the company earned $4.7 million, or 26 cents a share, on revenue of $174.9 million. Excluding charges and other one-time items, the company earned $9.6 million, or 53 cents a share. One analyst polled by Thomson First Call expected earnings of 75 cents a share and revenue of $186.3 million. During the year-earlier quarter, the company earned $34,000, or less than a penny a share, on revenue of $157.2 million. Excluding items, year-earlier earnings were $6.8 million, or 39 cents a share.
