Actual vs. Wall St. Expectations: TLAB fell short of the mean analyst estimate of a loss of 3 cents/share. Estimates ranged from a loss of one cent per share to a loss of 6 cents per share.

Quoting Management: “While international revenue grew 40% from a year ago, lower revenue in North America drove Tellabs’ first-quarter results,” said Rob Pullen, Tellabs president and chief executive officer. “Going forward, we will continue to invest in the smart mobile Internet through increased R&D spending to position Tellabs for long-term growth.”

Key Stats:

Gross margins fell 12.7 percentage points to 37.9%. The contraction appeared to be driven by falling revenue, as the figure fell 15.1% from the year earlier while costs rose 6.8%.

A year-over-year revenue decrease last quarter snaps a streak of four consecutive quarters of revenue increases. The best quarter in that span was the second quarter of the last fiscal year, which saw revenue rise 28.5%.
