CAMARILLO, Calif., June 01, 2016 (GLOBE NEWSWIRE) -- Semtech Corporation (Nasdaq:SMTC), a leading supplier of analog and mixed-signal semiconductors, today reported unaudited financial results for its first quarter of fiscal year 2017, which ended May 1, 2016.  

Net sales for the first quarter of fiscal year 2017 were $131.1 million, up 11 percent from the fourth quarter of fiscal year 2016 and up 1 percent from the first quarter of fiscal year 2016.

Gross margin, computed in accordance with U.S. generally accepted accounting principles (GAAP), for the first quarter of fiscal year 2017 was 59.9 percent compared to 58.6 percent in the fourth quarter of fiscal year 2016 and 60.3 percent in the first quarter of fiscal year 2016. 

GAAP net income for the first quarter of fiscal year 2017 was $6.9 million, or $0.11 per diluted share.  This compares to GAAP net income of $1.2 million or $0.02 per diluted share in the fourth quarter of fiscal year 2016, and GAAP net loss of $0.01 million or $0.00 per diluted share in the first quarter of fiscal year 2016. 

GAAP operating results for the fourth quarter of fiscal 2016 reflected an after-tax benefit of $1.8 million as a result of the fair value re-measurement of the Triune Systems earn-out liability.   

To facilitate the complete understanding of comparable financial performance between periods, the Company also presents performance results net of certain non-cash items and items that are not considered reflective of the Company’s core results over time.  The Company’s non-GAAP measures of gross margin, net income and earnings per diluted share exclude certain items as described below under “Non-GAAP Financial Measures.”

Excluding such items, non-GAAP net income for the first quarter of fiscal year 2017 was $19.5 million or $0.30 per diluted share.  Non-GAAP net income was $10.8 million or $0.17 per diluted share in the fourth quarter of fiscal year 2016, and was $17.9 million or $0.27 per diluted share in the first quarter of fiscal year 2016.

Non-GAAP gross margin for the first quarter of fiscal year 2017 was 60.2 percent.  Non-GAAP gross margin for the fourth quarter of fiscal year 2016 was 59.0 percent and 60.8 percent in the first quarter of fiscal year 2016.  

As of the end of the first quarter of fiscal year 2017, the Company had $216.0 million in cash, cash equivalents and marketable securities compared to $211.8 million in cash, cash equivalents and marketable securities at the end of fiscal year 2016.

Mohan Maheswaran, Semtech’s President and Chief Executive Officer, stated, “We were pleased to deliver Q1 fiscal 2017 results that were at the upper-end of our guidance for the second consecutive quarter.  We believe strong broad-based bookings during the quarter and the higher backlog entering Q2 ensure a strong start to fiscal year 2017.  Our focus on high growth markets while striving to achieve end-market balance should help the Company to outperform the industry this year, as we continue toward our goal to achieve $1 billion in revenue.”

Non-GAAP Financial Measures
To supplement the Company's consolidated financial statements prepared in accordance with GAAP, this release includes a non-GAAP presentation of gross margin, net income and earnings per diluted share and free cash flow.  The Company's measure of free cash flow excludes capital expenditures.  The Company’s non-GAAP measures of gross margin, net income and earnings per diluted share may exclude the following items, if any:

• Stock-based compensation expense
• Intangible amortization and impairments
• Restructuring, integration, transaction and other acquisition related expenses
• Litigation expenses or dispute settlement charges or gains
• Environmental and other reserves

To provide additional insight into the Company's second quarter outlook, this release also includes a presentation of forward-looking non-GAAP measures including gross margin, effective tax rate and earnings per diluted share. 

These non-GAAP financial measures are adjusted to exclude the items identified above because such items are either operating expenses which would not otherwise have been incurred by the Company in the normal course of the Company’s business operations or are not reflective of the Company’s core results over time.  These items may include recurring as well as non-recurring items, and no inference should be made that all of these adjustments, charges, costs or expenses are unusual, infrequent or non-recurring.  For example: certain restructuring and integration related expenses (which consist of employee termination costs, facility closure or lease termination costs, and contract termination costs) may be considered recurring given the Company’s ongoing efforts to be more cost effective and efficient; certain litigation expenses or dispute settlement charges or gains (which may include estimated losses for which we have established a reserve, as well as any actual settlements, judgments, or other resolutions against, or in favor of, the Company related to litigation, arbitration, disputes or similar matters, and insurance recoveries received by the Company related to such matters) may be viewed as recurring given that the Company may from time to time be involved in, and may resolve, litigation, arbitration, disputes, and similar matters; and certain acquisition-related adjustments or expenses may be deemed recurring given the Company's regular evaluation of potential transactions and investments.

Notwithstanding that certain adjustments, charges, costs or expenses may be considered recurring, in order to provide meaningful comparisons, the Company believes that it is appropriate to exclude such items because they are not reflective of the Company's core results and tend to vary based on timing, frequency and magnitude.

These non-GAAP financial measures are provided to enhance the user's overall understanding of the Company's comparable financial performance between periods.  In addition, the Company's management generally excludes the items noted above when managing and evaluating the performance of the business.  The financial statements provided with this release include reconciliations of these non-GAAP measures to their most comparable GAAP results for the first quarter of fiscal year 2017 and the fourth and first quarters of fiscal year 2016 along with a reconciliation of forward-looking earnings per diluted share to its most comparable GAAP measure for the second quarter of fiscal year 2017.  These additional non-GAAP financial measures should not be considered substitutes for any measures derived in accordance with GAAP and may be inconsistent with similar measures presented by other companies.
