Harmonic (HLIT) - Get Report shares jumped 8% late Wednesday as the company swung to a profit and raised estimates.

The Sunnyvale, Calif., broadband video systems maker posted an adjusted profit of $7.5 million, or a dime a share. Those numbers compare with a net loss of $2.6 million, or 4 cents a share, in the year-ago period. Analysts were looking for a 4-cent third-quarter pro forma profit, according to a Reuters Research survey.

Total sales for the quarter were $62.9 million, up from $53.3 million in the previous quarter and above the $61 million a year ago. The revenue level was in line with analysts' expectations.

"We are very pleased with our sales growth, improved operating efficiencies and profitability," CEO Pat Harshman said in a press release. "We continued to see strong bookings across our global customer base."

Looking ahead, the company says fourth quarter sales will be somewhere in a range between $67 million and $72 million. Analysts were expecting $68 million.

Harmonic shares rose 54 cents to $7.60 in after-hours trading Wednesday.
