“Our Storage business performed exceedingly well this past quarter with double-digit growth across all of its product lines,” said PMC president and chief executive officer, Greg Lang. “PMC remains well-positioned for continued growth into FY2015, as we expect to see increasing demand for our 12Gb/s SAS I/O controllers and expanders, advanced DIGI OTN processors, Flashtec™ NVMe controllers and our new RF Remote Radio Head products.”

Net income on a non-GAAP basis in the third quarter of 2014 excludes the following items: (i) $9.9 million amortization of purchased intangible assets; (ii) $5.2 million stock-based compensation expense, (iii) $1.0 million of acquisition-related costs and other adjustments as described in the accompanying GAAP to non-GAAP reconciliation table.

For a full reconciliation of each non-GAAP item used herein to the most directly comparable GAAP financial measure, please refer to the schedule included with this release. The Company believes the additional non-GAAP measures are useful to investors for the purpose of financial analysis. Management uses the non-GAAP measures internally to evaluate its in-period operating performance before gains, losses and other charges that are considered by management to be outside of the Company’s core operating results. In addition, the measures are used to plan for the Company’s future periods. However, non-GAAP measures are neither stated in accordance with, nor are they a substitute for, GAAP measures.
