Harmonic ( HLIT) missed its second-quarter revenue target but sees a stronger second half of the year.The Sunnyvale, Calif., broadband networking supplier posted a net loss of $2.9 million, or 4 cents a share, on sales of $53.3 million for the second quarter ended in June. Excluding one-time items, Harmonic's loss was $200,000, or less than a penny a share. Those numbers compare with a pro forma loss of $2.2 million, or 3 cents a share, on $59.8 million in revenue in the year-ago period. Analysts were looking for a 2-cent adjusted loss on $60.5 million in sales for the second quarter. The company blamed its weak top line on supply limitations, but remained optimistic about demand. "We saw bookings strengthen as the quarter progressed," CEO Patrick Harshman said in a press release Wednesday. Looking ahead, Harmonic expects to swing back to a profit in the second half on revenue of about $135 million for the two quarters. That is roughly $67.5 million per quarter. Analysts were expecting a 2 cent pro forma profit on $63.5 million in sales for the third quarter. Harmonic shares fell 4 cents to close at $4.25 Wednesday.
