CAMARILLO, Calif.--(BUSINESS WIRE)--March 2, 2016--Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today reported unaudited financial results for its fourth quarter and fiscal year 2016, which ended January 31, 2016.

Net sales for the fourth quarter of fiscal year 2016 were $118.6 million, up 2 percent from the third quarter of fiscal year 2016 and down 9 percent from the fourth quarter of fiscal year 2015. Net sales for the full fiscal year 2016 were $490.2 million, down 12 percent from $557.9 million for the full fiscal year 2015.

Gross profit margin, computed in accordance with U.S. generally accepted accounting principles (GAAP), for the fourth quarter of fiscal year 2016 was 58.6 percent compared to 60.1 percent in the third quarter of fiscal year 2016 and 56.1 percent in the fourth quarter of fiscal year 2015. GAAP gross profit margin for the full fiscal year 2016 was 59.8 percent compared to 58.9 percent for the full fiscal year 2015.

GAAP net income for the fourth quarter of fiscal year 2016 was $1.2 million, or $0.02 per diluted share. This compares to GAAP net income of $10.7 million or $0.16 per share in the third quarter of fiscal year 2016, and GAAP net loss of $15.4 million or ($0.23) per share in the fourth quarter of fiscal year 2015.

GAAP operating results for the fourth quarter of fiscal 2016 and third quarter of fiscal year 2016 reflected an after-tax benefit of $1.8 million and $9.4 million, respectively, as a result of the fair value re-measurement of the Triune Systems earn-out liability. Included in the GAAP operating results for the fourth quarter of fiscal year 2015 were charges that included $23.3 million for the restructuring and impairment-related costs associated with the Company’s reduction of its investment in the defense and microwave communications infrastructure market and the further reduction of its investment in the optical long-haul markets.

For the full fiscal year 2016, GAAP net income was $11.5 million or $0.17 per diluted share compared to GAAP net income of $27.9 million or $0.41 per diluted share for the full fiscal year 2015.

To facilitate the complete understanding of comparable financial performance between periods, the Company also presents performance results net of certain non-cash items or items that are not considered reflective of the Company’s core results over time. The Company’s non-GAAP measures of gross profit 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 fourth quarter of fiscal year 2016 was $10.8 million or $0.17 per diluted share. Non-GAAP net income was $12.1 million or $0.19 per diluted share in the third quarter of fiscal year 2016, and was $23.1 million or $0.34 per diluted share in the fourth quarter of fiscal year 2015. Non-GAAP net income for the full fiscal year 2016 was $56.4 million or $0.86 per diluted share. This compares to Non-GAAP net income for the full fiscal year 2015 of $104.0 million or $1.54 per diluted share.

Non-GAAP gross profit margin for the fourth quarter of fiscal year 2016 was 59.0 percent. Non-GAAP gross profit margin for the third quarter of fiscal year 2016 was 60.3 percent and 60.1 percent in the fourth quarter of fiscal year 2015. Non-GAAP gross profit margin for the full fiscal year 2016 was 60.2 percent, which compares to 60.3 percent non-GAAP gross profit margin for the full fiscal year 2015.

As of the end of the fourth quarter of fiscal year 2016, the Company had $211.8 million in cash, cash equivalents and marketable securities compared to $230.3 million in cash, cash equivalents and marketable securities at the end of fiscal year 2015.

Mohan Maheswaran, Semtech’s President and Chief Executive Officer, stated “While fiscal year 2016 proved challenging, we were pleased to deliver fiscal Q4 results that were ahead of our guidance. Demand from our Communication and Enterprise computing end markets strengthened throughout the quarter and record POS resulted in a 21% reduction in channel inventory.” Maheswaran continued, “Overall demand strengthened throughout the quarter and recent strong bookings across several businesses lead us to believe that we can return to outperforming the industry in fiscal year 2017.”

The results announced today are preliminary, as they are subject to the Company finalizing its closing procedures and annual audit by the Company's independent registered public accounting firm. As such, these results are subject to revision until the Company will have filed its annual report on Form 10-K for the fiscal year 2016.

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 profit 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 profit 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

To provide additional insight into the Company's first quarter outlook, this release also includes a presentation of forward-looking non-GAAP measures including gross profit 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 third and fourth quarters of fiscal year 2016 and fourth quarter of fiscal year 2015 along with a reconciliation of forward-looking earnings per diluted share to its most comparable GAAP measure for the first 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.
