Fourth Quarter 2019 Highlights

Fourth Quarter 2019 Financial Results

Net sales for the fourth quarter of 2019 were $719.3 million, compared to $711.0 million in the fourth quarter of 2018 and $716.8 million in the third quarter of 2019.

GAAP operating income for the fourth quarter of 2019 was $49.4 million, compared to $42.8 million in the fourth quarter of 2018 and $36.4 million in the third quarter of 2019.

GAAP net income for the fourth quarter of 2019 was $25.3 million, or $0.21 per diluted share. This compares to income of $52.5 million, or $0.42 per diluted share in the fourth quarter of 2018, and $15.9 million, or $0.14 per diluted share, in the third quarter of 2019. The fourth quarter of 2018 results reflect the release of a tax valuation allowance of $43.6 million.

On a non-GAAP basis, net income for the fourth quarter of 2019 was $43.9 million, or $0.41 per diluted share. This compares to non-GAAP net income of $55.0 million, or $0.52 per diluted share, for the fourth quarter of 2018 and $38.9 million, or $0.37 per diluted share, in the third quarter of 2019.

Adjusted EBITDA for the fourth quarter of 2019 was $111.3 million, or 15.5 percent of net sales, compared to adjusted EBITDA of $117.4 million, or 16.5 percent of net sales, for the fourth quarter of 2018 and $103.5 million, or 14.4 percent of net sales, for the third quarter of 2019.

“For the fourth quarter, TTM continued to generate strong cash flow and delivered revenue and earnings above the previously guided range,” said Tom Edman, CEO of TTM. “The year over year growth we experienced in the aerospace and defense, cellular and computing end markets offset weakness in our other commercial end markets.”

Full Year 2019 Financial Results

Net sales for fiscal year 2019 decreased to $2.69 billion from $2.85 billion in fiscal year 2018, a 5.5% decrease.

GAAP operating income for fiscal year 2019 was $120.1 million, a decrease from GAAP operating income of $159.1 million in fiscal year 2018.

GAAP net income for fiscal year 2019 was $41.3 million, or $0.39 per diluted share, compared to GAAP net income of $173.6 million, or $1.38 per diluted share, for fiscal year 2018. The 2018 results reflect the release of a tax valuation allowance of $118.2 million.

On a non-GAAP basis, net income for fiscal year 2019 was $120.5 million, or $1.13 per diluted share. This compares to fiscal year 2018 non-GAAP net income of $190.4 million, or $1.76 per diluted share.

Adjusted EBITDA for fiscal year 2019 was $376.2 million, or 14.0 percent of net sales, compared to $438.8 million, or 15.4 percent of net sales, for fiscal year 2018.

“In 2019, we finished with strong results in Q4 and made progress on our strategy of diversification, differentiation and discipline. Specifically, we acquired differentiating technology with an important asset purchase from i3 Technologies, which enables us to manufacture products that require finer lines and smaller spacing for our aerospace and defense and commercial end markets broadening our technology offerings in North America. In addition, in early January, we announced the sale of our more seasonal and generally more volatile mobility business,” continued Edman. “Finally, our financial discipline allowed us to generate significant year over year growth in cash flow despite year over year declines in revenues and profits.”

Business Outlook

Typically, in the first calendar quarter of every year, our China based factories are shut down over the Lunar New Year holiday. This year, due to government restrictions from the coronavirus. the shutdown has been extended approximately nine days to February 10^th. Assuming our factories in the PRC can resume production on February 10^th, TTM estimates that revenue for the first quarter of 2020 will be in the range of $580 million to $620 million, and non-GAAP net income will be in the range of $0.05 to $0.11 per diluted share, which includes approximately $0.09 negative impact from the additional nine days of closure. If the government extends the factory shutdown beyond February 10^th, our financial results would be further negatively impacted.

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 per diluted share, we are unable to predict with reasonable certainty or without unreasonable effort certain items that may affect a comparable measure calculated and presented in accordance with GAAP. Our expected non-GAAP net income 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 per diluted share calculated and presented in accordance with GAAP. Accordingly, a reconciliation of non-GAAP net income per diluted share to a comparable measure calculated and presented in accordance with GAAP is not available without unreasonable effort and has not been provided.
