Mr. Croteau concluded, “Adjusted revenue was up 4% sequentially, adjusted operating margins up 90 basis points and adjusted earnings per share increased 23% over the prior quarter. Looking ahead, we expect the combination of growing revenue contribution from our secular growth drivers and prudent cost management to provide leverage for expanding operating margins and profits over the course of fiscal 2019.”

Business Outlook

For the fiscal first quarter ending December 28, 2018, MACOM expects adjusted revenue to be in the range of $150 million to $156 million. Adjusted gross margin is expected to be between 55% and 57%, and adjusted earnings per share between $0.18 and $0.22 on an anticipated 66.5 million fully diluted shares outstanding.
