BERWYN, Pa —  November 8, 2018 — Trinseo (NYSE: TSE), a global materials company and manufacturer of plastics, latex binders and synthetic rubber, today reported its third quarter 2018 financial results with net sales of $1,200 million, net income of $75 million, and earnings per diluted share of $1.72. Third quarter Adjusted EBITDA was $143 million and Adjusted EPS was $1.83.

Net sales in the third quarter increased 9% versus prior year due mainly to the pass through of higher styrene and butadiene costs. In addition, higher sales volume in the Performance Plastics, Synthetic Rubber and Feedstocks segments was partially offset by lower sales volume in the Latex Binders and Polystyrene segments. Third quarter net income of $75 million was $42 million higher than prior year. Third quarter Adjusted EBITDA of $143 million was $23 million lower than prior year.

Prior year third quarter net income included a pre-tax charge of approximately $66 million related to the Company’s debt refinancing. In addition, the prior year third quarter results included an unfavorable pre-tax net timing impact of $24 million in comparison to an unfavorable impact of $4 million in the current year. Excluding these impacts, the lower year-over-year profitability was due to generally higher raw material costs, a slowdown in the automotive and tire markets, as well as a slowdown in demand across numerous end markets in China. In addition, in Polystyrene, we saw inventory destocking as customers awaited lower styrene prices in the fourth quarter.

Commenting on the Company’s performance, Chris Pappas, Trinseo President and Chief Executive Officer, said, “Our strong profitability in the first half of 2018 was met with challenges in the third quarter due to a variety of market factors that appeared late in the quarter. However, the diversity of our product portfolio assisted us in offsetting some of these challenges. We continue to exhibit strong cash generation and returned $52 million to shareholders via share repurchases and dividends during the quarter, and $144 million so far in 2018.”

Third Quarter Results and Commentary by Business Segment

·Latex Binders net sales of $278 million for the quarter increased 4% versus prior year. The increase was driven by the pass through of higher raw material costs, which was partially offset by lower sales volume, both in Europe from a declining paper market and in Asia due to global trade uncertainty. Adjusted EBITDA of $25 million was $8 million below prior year due primarily to lower margins as well as lower sales volume. Global trade uncertainty and rising raw material costs drove lower margins in Asia, while market competitiveness and product mix led to lower margins in North America.

·Synthetic Rubber net sales of $138 million for the quarter increased 16% versus prior year due primarily to the pass through of higher raw material costs. Adjusted EBITDA of $15 million was $21 million above prior year. A large unfavorable timing impact in the prior year, caused by the rapid decline of butadiene during that period, accounted for $28 million of favorable year-over-year variance. This impact was partially offset by margin compression from higher raw material costs and a generally weaker tire market.

·Performance Plastics net sales of $401 million for the quarter was 11% above prior year due to a mix of higher sales volume from the ABS expansion in China and the pass through of higher raw material costs. Adjusted EBITDA of $44 million was $19 million below prior year due to a combination of factors including a slowdown in the automotive industry, higher raw material costs and general market uncertainty in China due to ongoing trade dynamics. Specifically, in our ABS business, we saw trade flows shift with more imports into Europe from Asia due to weak demand in China. In our polycarbonate business, we saw increased supply enter an already weakened market, which led to margin compression.

·Polystyrene net sales of $252 million for the quarter was 6% above prior year driven by pass through of higher raw material costs which was partially offset by lower sales volume caused by weak market conditions, particularly in Asia, as well as customer destocking in Europe. Adjusted EBITDA of $5 million was $4 million lower than prior year. A combination of weaker market conditions in Asia as well as lower demand in Europe, as customers destocked in anticipation of lower polystyrene prices in the fourth quarter, led to volume and margin declines in comparison to prior year.

·Feedstocks net sales of $131 million for the quarter was 18% above prior year due to higher styrene-related sales and, to a smaller extent, higher styrene prices. Adjusted EBITDA of $40 million was $5 million lower than prior year due to a favorable net timing impact in the prior year. Excluding this impact, styrene margin was fairly flat, as higher margin in Asia was offset by lower margin in Europe.

·Americas Styrenics Adjusted EBITDA of $35 million for the quarter was $9 million lower than prior year due to lower styrene production as well as lower polystyrene margins.

Third Quarter Cash Generation

Cash provided by operating activities for the quarter was $56 million and capital expenditures were $31 million, resulting in Free Cash Flow for the quarter of $25 million. Third quarter cash from operations and Free Cash Flow included approximately $41 million of higher working capital. For a reconciliation of Free Cash Flow to cash provided by operating activities, see note 3 below.

2018 and 2019 Outlook

·Fourth quarter 2018 net income of $55 million to $63 million and earnings per diluted share of $1.27 to $1.46

·Fourth quarter 2018 Adjusted EBITDA of $110 million to $120 million and Adjusted EPS of $1.27 to $1.46

·Full year 2018 net income of $348 million to $356 million and earnings per diluted share of $7.96 to $8.15

·Full year 2018 Adjusted EBITDA of $618 million to $628 million and Adjusted EPS of $8.27 to $8.46

·Full year 2019 net income of $344 million to $368 million and Adjusted EBITDA of $600 million to $630 million

Commenting on the outlooks for the fourth quarter and full year 2018 and full year 2019, Pappas said, “We expect sequentially lower profitability in the fourth quarter due primarily to lower styrene margins. In the short-term, we see a continuation of the market conditions that affected the latter part of the third quarter, but we believe that as we progress into 2019 we will see some return to more normal buying patterns as supply chains begin to normalize, automotive production increases in Europe with more models passing the new WLTP standards and as the impact of China stimulus programs begins to become apparent. Overall, 2019 should be another year of solid earnings and very strong cash generation for Trinseo.”

Recast of Financial Statements for New Accounting Standard

On January 1, 2018, the Company adopted pension accounting guidance that requires employers to present the service cost component of net periodic benefit cost in the same statement of operations line item as other employee compensation costs arising from services rendered during the period. As a result of this adoption, for the three and nine months ended September 30, 2017, the Company reclassified net periodic benefit cost of $1.4 million and $3.8 million, respectively, from “Cost of sales”, and $0.7 million and $2.2 million, respectively, from “Selling, general, and administrative expenses”, to “Other expense (income), net” within the condensed consolidated statement of operations.

Use of non-GAAP measures

In addition to using standard measures of performance and liquidity that are recognized in accordance with accounting principles generally accepted in the United States of America (“GAAP”), we use additional measures of income excluding certain GAAP items (“non-GAAP measures”), such as Adjusted Net Income, EBITDA, Adjusted EBITDA and Adjusted EPS and measures of liquidity excluding certain GAAP items, such as Free Cash Flow. We believe these measures are useful for investors and management in evaluating business trends and performance each period.  These income measures are also used to manage our business and assess current period profitability, as well as to provide an appropriate basis to evaluate the effectiveness of our pricing strategies. Such measures are not recognized in accordance with GAAP and should not be viewed as an alternative to GAAP measures of performance

or liquidity, as applicable. The definitions of each of these measures, further discussion of usefulness, and reconciliations of non-GAAP measures to GAAP measures are provided in the Notes to Condensed Consolidated Financial Information presented herein.

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.

Note that the accelerated depreciation charges incurred 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 periods presented above relate to advisory and professional fees incurred in conjunction with the Company’s acquisition of API Plastics. The three months ended September 30, 2017 also include a non-cash fair value inventory adjustment recorded in conjunction with the API Plastics acquisition.

(d)Asset impairment charges or write-offs for the three months ended September 30, 2017 relate to the impairment of certain long-lived assets within the Company’s Performance Plastics segment.

(e)Other items for the three months ended September 30, 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, as well as fees incurred in conjunction with the Company’s term loan repricing which was completed during the third quarter of 2018. Other items for the three months ended September 30, 2017 primarily relate to fees incurred in conjunction with the Company’s debt refinancing completed during the third quarter of 2017.

(f)Adjusted to remove the tax impact of the items noted in (a), (b), (c), (d), (e), and (g). 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 September 30, 2018 excludes a $0.9 million discrete tax benefit related to certain legal entity restructurings, as well as $0.6 million in tax benefits related to provision to return adjustments.

(g)For the three months ended September 30, 2018 and 2017 the amounts exclude accelerated depreciation of $0.3 million and $0.6 million, respectively, 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 three months ended  December 31, 2018, as well as for the full year ended December 31, 2018.  See “Note on Forward-Looking Statements” above for a discussion of the limitations of these forecasts.

(h)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 three months ended  December 31, 2018, full year ended December 31, 2018 and full year ended December 31, 2019, we have not included estimates for these items.

(i)Weighted average shares calculated for the purpose of forecasting Adjusted EPS do not forecast significant future share transactions or events, such as repurchases, significant stock-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.

Third Quarter 2018 Earnings Management Commentary

November 8, 2018

Trinseo had third quarter net income of $75 million and Adjusted EBITDA of $143 million. In addition, earnings per diluted share was $1.72 and Adjusted EPS was $1.83. These results included $4 million of unfavorable net timing impacts, on a pre-tax basis, and were in line with guidance from our third quarter pre-release earnings announcement, but lower than our initial third quarter guidance we provided during the second quarter earnings call.

Key Points

·Third quarter total company profitability was impacted by generally higher raw material costs, a slowdown in the automotive and tire markets, as well as lower demand across numerous end markets in China

·Fourth quarter guidance of $55 million to $63 million of net income and $110 million to $120 million of Adjusted EBITDA is sequentially lower due primarily to lower styrene margins; assumes no short-term material improvement in market conditions and no unplanned styrene outages

·Full year 2019 guidance of $344 million to $368 million of net income and $600 million to $630 million of Adjusted EBITDA

·Continued strong cash generation

·Expect to generate $380 million to $410 million of cash from operations and $250 million to $280 million of Free Cash Flow for full year 2018

·$52 million and $144 million of cash returned to shareholders via share repurchases and dividends in Q3 and year to date, respectively

·Received authorization for new two million share repurchase program

Segment Results and Cash Generation

In Latex Binders we continued to see solid results as we shift our portfolio to more diversified chemistries, value-added product offerings and new markets. Third quarter Adjusted EBITDA of $25 million, which included $3 million of unfavorable timing impacts, was essentially in line with guidance excluding net timing impacts.

Synthetic Rubber third quarter Adjusted EBITDA of $15 million, which included a $3 million favorable net timing impact, was below guidance primarily due to lower SSBR sales volume, as the tire market remained softer than expected. Year-to-date SSBR sales volume was 6% higher than prior year and we expect a similar growth rate for the full year.

Performance Plastics third quarter Adjusted EBITDA of $44 million included an unfavorable net timing impact of approximately $1 million. This result was below guidance due to several factors, including higher raw material costs, lower automotive production, particularly in Europe due to new emissions standards, as well as lower demand across numerous end markets in China. In ABS and polycarbonate, the weakness in China not only impacted that region, but resulted in a higher level of imports into Europe, which affected the margins in that region as well. In polycarbonate, additional supply became available as new supply entered the market in China and as the operational issues of our competitors were resolved.

Polystyrene third quarter Adjusted EBITDA was $5 million, including approximately $2 million of unfavorable net timing. Third quarter profitability was below guidance due to weaker market conditions in Asia as well as customer destocking in Europe in anticipation of lower prices in the fourth quarter, both of which led to lower volume and margin.

Feedstocks third quarter Adjusted EBITDA was $40 million including an unfavorable net timing impact of $2 million. This result was above our guidance of $20 million due to sustained, higher styrene margins as well as impacts from some unplanned outages.

Americas Styrenics third quarter Adjusted EBITDA was $35 million which was in line with guidance. This result was $9 million lower than prior year due to lower styrene production and lower polystyrene margins.

Cash provided by operating activities for the quarter was $56 million and capital expenditures were $31 million, resulting in Free Cash Flow for the quarter of $25 million. Third quarter cash from operations and Free Cash Flow included an impact of approximately $41 million from higher working capital. At the end of the quarter, we had $421 million of cash after $35 million of share repurchases during the quarter and $17 million of dividends. On a year to date basis we have returned $144 million to shareholders via these mechanisms.

Guidance

In total for Trinseo we expect fourth quarter net income of $55 million to $63 million, Adjusted EBITDA of $110 million to $120 million, and diluted EPS and Adjusted EPS of $1.27 to $1.46. This expectation assumes no material improvement in the market conditions that affected the latter part of the third quarter, and is sequentially lower due mainly to lower expected styrene margins as more capacity returns to operation.

For full year 2018 guidance, we are now estimating net income of $348 million to $356 million, diluted EPS of $7.96 to $8.15 and Adjusted EPS of $8.27 to $8.46. We are also estimating Adjusted EBITDA of $618 million to $628 million. In addition, for the full year 2018, we expect cash from operations of $380 million to $410 million and capital expenditures of about $130 million, resulting in $250 million to $280 million of Free Cash Flow. This estimate assumes cash paid for interest of $50 million and cash paid for taxes of $90 million.

Our fourth quarter and full year estimates assume minimal impact from net timing and no unplanned styrene outages during the fourth quarter. Fourth quarter segment guidance is below, along with our assumptions for these estimates:

·Latex Binders (~$28 million Adjusted EBITDA):  Steady performance, similar to the third quarter excluding net timing impacts

·Synthetic Rubber ($10 million to $15 million):  Increasing SSBR sales volume from winter tire production and seasonality

·Performance Plastics ($35 million to $40 million):  ABS and polycarbonate market pressures persist from weakness in China and lower automotive production

·Polystyrene (~$10 million):  Higher sequential profitability; already seeing an uptick in fourth quarter buying activity following the third quarter destocking

·Feedstocks (~$20 million):  Lower sequential results in the fourth quarter as more supply returns to operation following third quarter outages

·Americas Styrenics (~$30 million):  Lower styrene margins following third quarter outages

We experienced very good business dynamics through the first 8 months of 2018. Despite the well-known industry challenges outlined for the last third of the year, Trinseo expects a solid year with excellent cash generation and progress on various components of our growth agenda.

As we look to 2019 we see another year of solid earnings and strong cash generation. Our guidance midpoint of $356 million of net income, $615 million of Adjusted EBITDA and $8.21 of EPS is based on an expectation of a gradual return to more normal buying patterns for Synthetic Rubber and Performance Plastics, continued solid performance from Latex Binders and strong operating rates in styrene and polystyrene. This guidance assumes no unplanned styrene outages in 2019.

With relatively low capital expenditures, a tax rate of about 20% and cash interest similar to 2018, Trinseo should have another year of strong cash generation in 2019. Cash provided by operating activities and Free Cash Flow are expected to be between $370 million and $420 million, and $250 million and $300 million, respectively, and we expect to maintain healthy returns of cash to shareholders.

Use of non-GAAP measures

In addition to using standard measures of performance and liquidity that are recognized in accordance with accounting principles generally accepted in the United States of America (“GAAP”), we use additional measures of income excluding certain GAAP items (“non-GAAP measures”), such as Adjusted EBITDA and Adjusted EPS, and measures of liquidity excluding certain GAAP items, such as Free Cash Flow. We believe these measures are useful for investors and management

in evaluating business trends and performance each period.  These income measures are also used to manage our business and assess current period profitability, as well as to provide an appropriate basis to evaluate the effectiveness of our pricing strategies. Such measures are not recognized in accordance with GAAP and should not be viewed as an alternative to GAAP measures of performance or liquidity, as applicable. The definitions of each of these measures, further discussion of usefulness, and reconciliations of non-GAAP measures to GAAP measures are provided in the Form 8-K filing for this commentary in Exhibit 99.1-Press Release, dated November 8, 2018.

In 2018, we estimate that we will produce approximately 700 kilotons of styrene in Western Europe and purchase approximately 185 kilotons of styrene in Asia with cost-based economics. With all other inputs remaining equal, a $50 per metric ton change in styrene margins would be expected to impact the Feedstocks reporting segment’s annual Adjusted EBITDA by approximately $35 million in Europe and approximately $9 million in Asia. Other factors that could impact the Feedstocks segment Adjusted EBITDA include, but are not limited to, utilities, freight, manufacturing costs, overhead costs, production outages, currency, discounts of styrene, benzene, and ethylene, as well as raw material timing.
