• Adjusted EBITDA of $102 million

BERWYN, Pa —  May 2, 2019 — Trinseo (NYSE: TSE), a global materials company and manufacturer of plastics, latex binders and synthetic rubber, today reported its first quarter 2019 financial results.

Net sales in the first quarter decreased 10% versus prior year. The pass through of lower raw material cost resulted in a 15% decrease in net sales. This impact was partially offset by higher sales volumes across all segments except Synthetic Rubber. First quarter net income of $36 million was $84 million lower than prior year and first quarter Adjusted EBITDA of $102 million was $93 million lower than prior year. These decreases were mainly due to lower margins in the Feedstocks, Performance Plastics and Latex Binders segments and lower equity affiliate income from Americas Styrenics. Overall, the results of the quarter were affected by macroeconomic dynamics in China as well as weakness in certain key markets such as automotive and tires. Net income was also impacted by approximately $9 million of higher pre-tax spending related to the transition of business services from The Dow Chemical Company.

Commenting on the Company’s performance, Frank Bozich, Trinseo President and Chief Executive Officer, said, “While improved versus the fourth quarter, our first quarter results were affected by continued weak automotive and tire markets and the weak economic environment in China. Despite this, we delivered very strong cash generation in the first quarter as a result of actions taken to reduce inventory levels.”

First Quarter Results and Commentary by Business Segment

• Latex Binders net sales of $224 million for the quarter decreased 12% versus prior year due to the pass through of lower raw material costs. Volume was higher versus prior year, as increases to the paper, board and carpet markets in North America and Europe were partially offset by a decrease to the paper market in Asia from a customer outage. Adjusted EBITDA of $18 million was $9 million below prior year due to lower margins from raw material dynamics as well as competitive market conditions.
• Synthetic Rubber net sales of $125 million for the quarter decreased 16% versus prior year due mainly to lower SSBR and ESBR sales volume as well as currency impacts. Adjusted EBITDA of $9 million included an unfavorable net timing impact and was $17 million below prior year. The year-over-year decline was due mainly to lower SSBR and ESBR sales volume as well as unfavorable net timing.
• Performance Plastics net sales of $369 million for the quarter was 8% below prior year due mainly to lower prices from the pass through of lower styrene cost as well as lower polycarbonate prices from a decrease in industry operating rates. Adjusted EBITDA of $36 million was $30 million below prior year due to lower polycarbonate and ABS margins from a combination of factors including a slowdown in the automotive industry and general market softness in China. While ABS margins were lower versus prior year, we are encouraged that margin levels have experienced some recovery and are currently at the highest levels since the second quarter of 2018.
• Polystyrene net sales of $228 million for the quarter were 5% below prior year mainly due to pass through pricing which was partially offset by higher sales from customer restocking and more favorable market conditions. Adjusted EBITDA of $17 million was $7 million higher than prior year due mainly to higher volume.
• Feedstocks net sales of $67 million for the quarter were 10% below prior year due mainly to the pass through of lower market styrene prices, which was partially offset by higher styrene-related sales. Adjusted EBITDA of $17 million was $25 million lower than prior year due to lower margin as well as lower production volume from unplanned outages at our Terneuzen and Boehlen styrene manufacturing facilities.
• Americas Styrenics Adjusted EBITDA of $32 million for the quarter was $14 million below prior year due mainly to lower styrene margins as well as a planned styrene maintenance outage in the first quarter of 2019.

First Quarter Cash Generation

Cash provided by operating activities for the first quarter was $153 million and capital expenditures were $25 million, resulting in Free Cash Flow for the quarter of $128 million. First quarter cash from operations and Free Cash Flow included approximately $105 million of lower working capital. The Company repurchased about 0.7 million shares in the first quarter for approximately $37 million. For a reconciliation of Free Cash Flow to cash provided by operating activities, see Note 3 below.

Outlook

• Full year 2019 net income of $237 million to $290 million and earnings per diluted share of $5.73 to $7.00
• Full year 2019 Adjusted EBITDA of $500 million to $560 million and Adjusted EPS of $6.00 to $7.27

Commenting on the outlook for 2019, Bozich said, “While we have seen signs of improved demand across some of our markets, the automotive and tire markets remain weak, as do many of the end markets in China into which we sell. Amid these conditions, we have initiated a number of working capital and cost initiatives to improve operating results. We are also evaluating strategic alternatives for our polycarbonate manufacturing facility in Stade, Germany due to significantly declining polycarbonate margins resulting from low demand and new capacity in China. This is the first action from our ongoing strategic review of our business portfolio. We are cautiously optimistic about better economic conditions in the second half of 2019 and we remain focused on cash generation and cost management.”

Note 1: Net sales by Segment

* The results of this segment are comprised entirely of earnings from Americas Styrenics, our 50%-owned equity method investment. As such, we do not separately report net sales of Americas Styrenics within our condensed consolidated statements of operations.

Note 2: Reconciliation of Non-GAAP Performance Measures to Net income

EBITDA is a non-GAAP financial performance measure that we refer to in making operating decisions because we believe it provides our management as well as our investors with meaningful information regarding the Company’s operational performance. We believe the use of EBITDA as a metric assists our board of directors, management and investors in comparing our operating performance on a consistent basis.

We also present Adjusted EBITDA as a non-GAAP financial performance measure, which we define as income from continuing operations before interest expense, net; income tax provision; depreciation and amortization expense; loss on extinguishment of long-term debt; asset impairment charges; gains or losses on the dispositions of businesses and assets; restructuring charges; acquisition related costs and other items. In doing so, we are providing management, investors, and credit rating agencies with an indicator of our ongoing performance and business trends, removing the impact of transactions and events that we would not consider a part of our core operations.

Lastly, we present Adjusted Net Income and Adjusted EPS as additional performance measures. Adjusted Net Income is calculated as Adjusted EBITDA (defined beginning with net income, above), less interest expense, less the provision for income taxes and depreciation and amortization, tax affected for various discrete items, as appropriate. Adjusted EPS is calculated as Adjusted Net Income per weighted average diluted shares outstanding for a given period. We believe that Adjusted Net Income and Adjusted EPS provide transparent and useful information to management, investors, analysts and other stakeholders in evaluating and assessing our operating results from period-to-period after removing the impact of certain transactions and activities that affect comparability and that are not considered part of our core operations.

There are limitations to using the financial performance measures noted above. These performance measures are not intended to represent net income or other measures of financial performance. As such, they should not be used as alternatives to net income as indicators of operating performance. Other companies in our industry may define these performance measures differently than we do. As a result, it may be difficult to use these or similarly-named financial measures that other companies may use, to compare the performance of those companies to our performance. We compensate for these limitations by providing reconciliations of these performance measures to our net income, which is determined in accordance with GAAP.

(a) Net gains on disposition of businesses and assets for the threee months ended March 31, 2019 and 2018 relate to contingent consideration earned for the performance of our former latex business in Brazil, which we divested in 2016.

(b) Restructuring and other charges for the three months ended March 31, 2019 and 2018 primarily relate to decommissioning, contract termination, and employee termination benefit charges incurred in connection with the upgrade and replacement of our compounding facility in Terneuzen, The Netherlands as well as our decision to cease manufacturing activities at our latex binders manufacturing facility in Livorno, Italy. Note that the accelerated depreciation charges incurred in 2018 as part of the upgrade and replacement of the Company’s compounding facility in Terneuzen, The Netherlands are included within the “Depreciation and amortization” caption above, and therefore are not included as a separate adjustment within this caption.

(c) Acquisition transaction and integration costs for the three months ended March 31, 2018 relate to advisory and professional fees incurred in conjunction with the Company’s acquisition of API Plastics.

(d) Other items for the three months ended March 31, 2019 and 2018 primarily relate to advisory and professional fees incurred in conjunction with the Company’s initiative to transition business services from The Dow Chemical Company, including certain administrative services such as accounts payable, logistics, and IT services.

(e) Adjusted to remove the tax impact of the items noted in (a), (b), (c), (d), and (f). The income tax expense (benefit) related to these items was determined utilizing either (1) the estimated annual effective tax rate on our ordinary income based upon our forecasted ordinary income for the full year or, (2) for items treated discretely for tax purposes we utilized the applicable rates in the taxing jurisdictions in which these adjustments occurred. Additionally, the three months ended March 31, 2018 excludes a $0.5 million tax benefit recognized during the period related to provision to return adjustments.

(f) For the three months ended March 31, 2019, the amount excludes accelerated depreciation of $0.5 million related to the shortening of the useful life of certain information technology assets related to the transition of business services from The Dow Chemical Company (noted in (d) above). For the three months ended March 31, 2018, the amount excludes accelerated depreciation of $0.3 million related to the upgrade and replacement of the Company’s compounding facility in Terneuzen, The Netherlands.

For the same reasons discussed above, we are providing the following reconciliation of forecasted net income to forecasted Adjusted EBITDA and Adjusted EPS for the full year ended December 31, 2019. See “Note on Forward-Looking Statements” above for a discussion of the limitations of these forecasts.

(g) Reconciling items to Adjusted EBITDA and Adjusted Net Income are not typically forecasted by the Company based on their nature as being primarily driven by transactions that are not part of the core operations of the business. As such, for the forecasted full year ended December 31, 2019, we have not included estimates for these items.

(h) Weighted average shares calculated for the purpose of forecasting Adjusted EPS do not forecast significant future share transactions or events, such as repurchases, significant share-based compensation award grants, and changes in the Company’s share price. These are all factors which could have a significant impact on the calculation of Adjusted EPS during actual future periods.

Note 3: Reconciliation of Non-GAAP Liquidity Measures to Cash from Operations

The Company uses Free Cash Flow to evaluate and discuss its liquidity position and results. Free Cash Flow is defined as cash from operating activities, less capital expenditures. We believe that Free Cash Flow provides an indicator of the Company’s ongoing ability to generate cash through core operations, as it excludes the cash impacts of various financing transactions as well as cash flows from business combinations that are not considered organic in nature. We also believe that Free Cash Flow provides management and investors with a useful analytical indicator of our ability to service our indebtedness, pay dividends (when declared), and meet our ongoing cash obligations.

Free Cash Flow is not intended to represent cash flows from operations as defined by GAAP, and therefore, should not be used as an alternative for that measure. Other companies in our industry may define Free Cash Flow differently than we do. As a result, it may be difficult to use this or similarly-named financial measures that other companies may use, to compare the liquidity and cash generation of those companies to our own. The Company compensates for these limitations by providing the reconciliation below, which is determined in accordance with GAAP.
