Fourth Quarter 2017 Highlights

Fourth Quarter 2017 Financial Results

Net sales for the fourth quarter of 2017 were $739.3 million, compared to $706.5 million in the fourth quarter of 2016 and $668.8 million in the third quarter of 2017.

GAAP operating income for the fourth quarter of 2017 was $71.0 million, compared to $69.6 million in the fourth quarter of 2016 and $44.1 million in the third quarter of 2017.

GAAP net income attributable to stockholders for the fourth quarter of 2017 was $49.2 million, or $0.40 per diluted share. This compares to a GAAP net loss attributable to stockholders of $2.0 million, or $0.02 per share, in the fourth quarter of 2016 and a GAAP net income of $21.5 million, or $0.19 per diluted share, in the third quarter of 2017.

On a non-GAAP basis, net income attributable to stockholders for the fourth quarter of 2017 was $61.2 million, or $0.57 per diluted share. This compares to non-GAAP net income attributable to stockholders of $59.8 million, or $0.58 per diluted share, for the fourth quarter of 2016 and $33.4 million, or $0.32 per diluted share, in the third quarter of 2017.

Adjusted EBITDA for the fourth quarter of 2017 was $121.7 million, or 16.5 percent of net sales, compared to adjusted EBITDA of $128.5 million, or 18.2 percent of net sales, for the fourth quarter of 2016 and $85.7 million, or 12.9 percent of net sales, for the third quarter of 2017.

“TTM delivered the fifth consecutive quarter of year on year organic growth with revenues and operating performance that significantly exceeded expectations” said Tom Edman, CEO of TTM. “On a year over year basis, the fastest growth in the fourth quarter came from the cellular and the aerospace and defense end markets. This drove cash flow from operations to a record high of $152.7 million in the quarter.”

Full Year 2017 Financial Results

Net sales for fiscal year 2017 increased to $2.7 billion from $2.5 billion in fiscal year 2016, a 4.9% increase year over year.

GAAP operating income for fiscal year 2017 was $212.8 million, an increase from GAAP operating income of $173.5 million in fiscal year 2016.

GAAP net income attributable to stockholders for fiscal year 2017 was $124.2 million, or $1.04 per diluted share, compared to GAAP net income attributable to stockholders of $34.9 million, or $0.34 per diluted share, for fiscal year 2016.

On a non-GAAP basis, net income attributable to stockholders for fiscal year 2017 was $167.1 million, or $1.57 per diluted share. This compares to fiscal year 2016 non-GAAP net income attributable to stockholders of $142.3 million, or $1.40 per diluted share.

Adjusted EBITDA for fiscal year 2017 was $388.6 million, or 14.6 percent of net sales, compared to $395.4 million, or 15.6 percent of net sales, for fiscal year 2016.

“2017 continued to validate TTM’s strategy of diversification, differentiation and discipline. We saw solid organic growth in the aerospace and defense, cellular and computing end markets that more than offset the decline in the networking and communications end markets,” continued Edman. “I would like to thank our employees for their tremendous efforts to achieve these results for the year 2017.”

“In the first quarter of 2018, we face short term seasonal challenges in our consumer oriented cellular and computing end markets, but remain optimistic for full year growth in nearly all of our end markets driven by megatrends such as growing automotive electronic content, increased aerospace and defense procurement, and upgrades in cellular phones.”

Business Outlook

For the first quarter of 2018, TTM estimates that revenue will be in the range of $610 million to $660 million, and non-GAAP net income attributable to stockholders will be in the range of $0.22 to $0.28 per diluted share.

Forward-Looking Statements

This release contains forward-looking statements that relate to future events or performance. TTM cautions you that such statements are simply predictions and actual events or results may differ materially. These statements reflect TTM’s current expectations, and TTM does not undertake to update or revise these forward looking statements, even if experience or future changes make it clear that any projected results expressed or implied in this or other TTM statements will not be realized. Further, these statements involve risks and uncertainties, many of which are beyond TTM’s control, which could cause actual results to differ materially from the forward-looking statements. These risks and uncertainties include, but are not limited to, general market and economic conditions, including interest rates, currency exchange rates and consumer spending, demand for TTM’s products, market pressures on prices of TTM’s products, warranty claims, changes in product mix, contemplated significant capital expenditures and related financing requirements, TTM’s dependence upon a small number of customers and other factors set forth in the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of the Company’s public reports filed with the SEC.

About Our Non-GAAP Financial Measures

This release includes information about TTM’s adjusted EBITDA, non-GAAP net income and non-GAAP earnings per share, all of which are non-GAAP financial measures. TTM presents non-GAAP financial information to enable investors to see TTM through the eyes of management and to provide better insight into TTM’s ongoing financial performance.

A material limitation associated with the use of the above non-GAAP financial measures is that they have no standardized measurement prescribed by GAAP and may not be comparable to similar non-GAAP financial measures used by other companies. TTM compensates for these limitations by providing full disclosure of each non-GAAP financial measure and reconciliation to the most directly comparable GAAP financial measure. However, the non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP.

With respect to the Company’s outlook for non-GAAP net income attributable to stockholders per diluted share, we are unable to predict with reasonable certainty or without unreasonable effort certain items that may affect such measure calculated and presented in accordance with GAAP. Our expected non-GAAP net income attributable to stockholders per diluted share excludes primarily the future impact of restructuring actions, impairment charges, unusual gains and losses, and tax adjustments. These reconciling items are highly variable and difficult to predict due to various factors outside of management’s control and could have a material impact on our future period net income attributable to stockholders per diluted share calculated and presented in accordance with GAAP. Accordingly, a reconciliation of non-GAAP net income attributable to stockholders per diluted share to such measure calculated and presented in accordance with GAAP is not available without unreasonable effort and has not been provided.
