TPI Composites, Inc. Announces Second Quarter 2017 Earnings Results and the Signing of a New Supply Agreement for Two Lines in China

SCOTTSDALE, Ariz., Aug. 08, 2017 (GLOBE NEWSWIRE) -- TPI Composites, Inc. (Nasdaq:TPIC), the only independent manufacturer of composite wind blades with a global footprint, today reported financial results for the second quarter ended June 30, 2017.

1. Number of wind blade sets (which consist of three wind blades) invoiced worldwide in the period.
2. Estimated megawatts of energy capacity to be generated by wind blade sets invoiced in the period.
3. Number of manufacturing lines that are dedicated to our customers under long-term supply agreements.
4. Number of manufacturing lines installed and either in operation, startup or transition.
5. Number of manufacturing lines in a startup phase during the period.
6. Number of manufacturing lines that were being transitioned to a new wind blade model during the period.

“We are pleased with our strong operational and financial performance in the second quarter of 2017 in which we exceeded both our total billings and adjusted EBITDA targets,” said Steve Lockard, TPI Composites’ President and Chief Executive Officer. “We are also announcing today that we signed a multiyear supply agreement to supply blades from two manufacturing lines in our factory in Taicang, China. This will help backfill volume in our Taicang plant when we commence production before the end of Q1 of 2018. This deal highlights our commitment to our strategy of global growth, customer diversification and expanded profitability.”

“We expect solid results for the balance of the year and reaffirm our guidance range of $930 million to $950 million for total billings for the year.  We currently have approximately $4.4 billion of revenue under long-term contracts covering 48 molds and a strong global pipeline of opportunities to support our growth targets. We remain confident in our ability to expand our production lines globally across numerous partners and continue to target a 25% revenue CAGR through 2019.”

Second Quarter 2017 Financial Results
Net sales for the three months ended June 30, 2017 increased by $53.9 million or 27.8% to $248.2 million compared to $194.3 million in the same period in 2016. Net sales of wind blades increased by 31.1% to $239.8 million for the three months ended June 30, 2017 as compared to $182.9 million in the same period in 2016. The increase was primarily driven by a 36% increase in the number of wind blades delivered during the three months ended June 30, 2017 compared to the same period in 2016 primarily from our China and Mexico plants, partially offset by a decline in the average sales prices of the same blade models delivered in both periods as a result of geographic mix and savings in raw material costs, a portion of which we share with our customers, and foreign currency fluctuations in China and Turkey. Net sales from the manufacturing of precision molding and assembly systems during the three months ended June 30, 2017 decreased to $4.8 million from $10.0 million in the same period in 2016. This decrease was primarily the result of our customers requiring less precision molding and assembly systems from our Rhode Island facility during the three months ended June 30, 2017. Total billings for the three months ended June 30, 2017 increased by $34.9 million or 17.8% to $231.1 million compared to $196.1 million in the same period in 2016. The impact of the strengthening of the U.S. dollar against the Euro at our Turkey operations and the Chinese Renminbi at our China operations on consolidated net sales and total billings for the three months ended June 30, 2017 were reductions of 2.0% and 1.9%, respectively, but were not significant for the three months ended June 30, 2016.

Total cost of goods sold for the three months ended June 30, 2017 was $213.6 million and included aggregate costs of $10.5 million related to startup costs in our new plants in Mexico and Turkey and the startup of a new wind blade model for one of our customers in Dafeng, China. This compares to total cost of goods sold for the three months ended June 30, 2016 of $171.4 million, including aggregate costs of $3.1 million related to startup costs in our new plants in Mexico and Turkey as well as the transition of wind blade models in our original plant in Mexico. Cost of goods sold as a percentage of net sales of wind blades decreased by three percentage points during the three months ended June 30, 2017 as compared to the same period in 2016, driven by improved operating efficiencies, the impact of savings in raw material costs and foreign currency fluctuations, partially offset by the increase in startup and transition costs. Similar to the impact to net sales above, the impact of the strengthening of the U.S. dollar against the Euro, Turkish Lira, Chinese Renminbi and Mexican Peso reduced consolidated cost of goods sold by 3.9% for three months ended June 30, 2017 but was not significant for the three months ended June 30, 2016.

Net income for the three months ended June 30, 2017 was $13.9 million, as compared to $11.6 million in the same period in 2016. The increase was primarily due to the reasons set forth above.

Net income attributable to preferred shareholders was $2.4 million for the three months ended June 30, 2016 and there was none in the 2017 period as following our IPO in July 2016, all of our preferred shares were converted to common shares.

Net income attributable to common shareholders was $13.9 million for the three months ended June 30, 2017, compared to $9.1 million in the same period in 2016. This was primarily due to the improved operating results discussed above. Diluted earnings per share was $0.41 for the three months ended June 30, 2017, compared to $2.15 for the three months ended June 30, 2016.

EBITDA for three months ended June 30, 2017 increased to $27.5 million, compared to $20.8 million during the same period in 2016. The EBITDA margin increased to 11.1% compared to 10.7% in the 2016 period. Adjusted EBITDA for three months ended June 30, 2017 increased to $30.8 million compared to $20.8 million during the same period a year ago. The Adjusted EBITDA margin increased to 12.4%, compared to 10.7% during the same period a year ago.

Capital expenditures were $9.8 million for three months ended June 30, 2017 compared to $3.4 million during the same period a year ago. Capex is primarily related to our new facilities in Mexico and Turkey.

We ended the quarter with $130.8 million of cash and cash equivalents and net debt was a net cash position of $0.5 million as compared to net debt of $6.4 million as of December 31, 2016.

August 8 , 2017 18 Appendix - Non - GAAP Information This presentation includes unaudited non - GAAP financial measures including total billings, EBITDA, adjusted EBITDA, net debt and free cash flow . We define total billings as the total amounts we have invoiced our customers for products and services for which we are entitled to payment under the terms of our long - term supply agreements or other contractual agreements . We define EBITDA as net income (loss) attributable to the Company plus interest expense ( including losses on the extinguishment of debt and net of interest income ), income taxes, and depreciation and amortization . We define adjusted EBITDA as EBITDA plus any share - based compensation expense, plus or minus any gains or losses from foreign currency remeasurement . We define net debt as the total principal amount of debt outstanding less unrestricted cash and equivalents . We define free cash flow as net cash flow generated from operating activities less capital expenditures . We present non - GAAP measures when we believe that the additional information is useful and meaningful to investors . Non - GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similar measures presented by other companies . The presentation of non - GAAP financial measures is not intended to be a substitute for, and should not be considered in isolation from, the financial measures reported in accordance with GAAP . See below for a reconciliation of certain non - GAAP financial measures to the comparable GAAP measures .
