Trinseo (NYSE: TSE), a specialty material solutions provider, today reported its second quarter 2022 financial results. Net sales in the second quarter increased 12% versus prior year. Higher prices resulted in a 14% increase mainly due to the pass through of higher raw material costs as well as the addition of the acquired PMMA and Aristech Surfaces businesses within the Engineered Materials segment. These increases were partially offset by lower volumes across several segments mainly from lower demand to building & construction, automotive, appliance and consumer electronics applications, including the impact of COVID-19 lockdowns in China. Second quarter net income from continuing operations of $37 million was $96 million below prior year and Adjusted EBITDA of $164 million was $75 million lower than the Company’s record performance in the prior year. These decreases were primarily due to lower margins in Feedstocks and Polystyrene as well as lower sales volume.

Commenting on the Company’s second quarter performance, Frank Bozich, President and Chief Executive Officer of Trinseo, said, “We delivered solid second quarter results in a challenging operating environment that is forcing both Trinseo and our customers to contend with issues including cautious spending in Europe from an uncertain geopolitical situation and significantly higher energy costs, COVID-19 lockdowns in China, and persistent supply chain constraints including a lack of semiconductor chips. Our dedicated employees deserve high praise for navigating this challenging environment to keep our customers supplied with our products and solutions as we leverage our global footprint to provide stable earnings.”

Second Quarter Results and Commentary by Business Segment

• Engineered Materials net sales of $301 million for the quarter increased 66% versus prior year and Adjusted EBITDA of $34 million increased $6 million versus prior year. These increases were primarily attributable to one additional month of the acquired PMMA business and a full quarter of the acquired Aristech Surfaces business. The current period results included a one-time charge of $4 million related to a contract review with a significant supplier. While the integration and synergy realization of the newly acquired businesses are both on track, segment results remain challenged by ongoing industry production issues in automotive as well as weakening demand for and destocking of consumer durables.

• Latex Binders net sales of $354 million for the quarter increased 14% versus prior year due to the passthrough of higher raw materials such as styrene and butadiene as well as pricing actions. Sales volume was slightly lower than prior year as lower sales to carpet applications was mostly offset by healthy demand in North America to paper & board and CASE applications. Adjusted EBITDA of $29 million was $3 million lower than prior year as pricing actions were more than offset by a $6 million negative net timing variance.

• Base Plastics net sales of $362 million for the quarter were 9% lower than prior year. Higher price accounted for a 12% increase in net sales due mainly to the passthrough of higher raw materials. This was more than offset by an 18% headwind from lower volumes, mainly in ABS, due to broad demand weakness in Europe and COVID-19 impacts in Asia. Adjusted EBITDA of $46 million was $36 million below prior year due to lower volumes as well as a margin decline in polycarbonate from higher raw material and utility costs and a softer demand environment. Automotive demand was sequentially similar.

• Polystyrene net sales of $312 million for the quarter was $1 million below prior year as higher prices from the passthrough of raw material costs were offset by volume declines caused by lower demand in China for appliances. Adjusted EBITDA of $23 million was $28 million lower than prior year from weaker market conditions in Asia, including impacts from COVID-19 lockdowns, as well as raw material volatility in Europe.

• Feedstocks Adjusted EBITDA of $14 million was $26 million lower than prior year due to higher utility costs and styrene production outages.

• Americas Styrenics Adjusted EBITDA of $39 million for the quarter was $9 million higher than prior year as higher styrene margins were partially offset by lower sales volume due to a three-week outage at the St. James styrene facility.

2022 Full-Year Outlook

• Full-year 2022 net income from continuing operations of $28 million to $63 million and Adjusted EBITDA of $475 million to $525 million

• Full-year 2022 cash from operations of approximately $250 million and Free Cash Flow of approximately $100 million

Commenting on the outlook for 2022, Bozich said, “I’m pleased with our results for the first half of the year as the Adjusted EBITDA was the third highest first half result in the Company’s history despite the very challenging business environment. This performance is a reflection of the portfolio changes we’ve made over the past 15 months. However, increased uncertainty due to the ongoing war in Ukraine and the associated rise in energy prices has begun to negatively influence demand in Europe. This has led to our full-year guidance revision.”

Bozich continued, “Despite the recently announced pause of the process to sell our Styrenics business, our transformation strategy has not changed. Due to the significant interest we saw during the process, we anticipate a successful separation of these assets when the market conditions improve. In the interim, we will leverage the significant free cash flow of these assets to fund organic growth opportunities in Engineered Materials, Base Plastics and Latex Binders applications with higher margins, higher growth and less cyclicality. We will continue to invest in our global recycling capabilities to provide our customers with a greater scope of circular product options. More information on our improving sustainable product portfolio, as well as our progress toward our 2030 Sustainability Goals, can be found in the July release of our 12^th annual Corporate Sustainability Report.”

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 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.

Notes to Condensed Consolidated Financial Information

(Unaudited)

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, which is defined as income from continuing operations before interest expense, net; income tax provision; depreciation and amortization expense. We refer to EBITDA 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 benefits, 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 from continuing operations, 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.

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, 2022. See “Note on Forward-Looking Statements” above for a discussion of the limitations of these forecasts.

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

The Company uses certain measures, such as Free Cash Flow as non-GAAP measures, 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 useful analytical indicators 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 alternatives 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 following detail, which is determined in accordance with GAAP.

Free Cash Flow

For the same reasons discussed above, we are providing the following reconciliation of forecasted cash provided by operations and cash used for capital expenditures to forecasted Free Cash Flow for the year ended December 31, 2022. See “Note on Forward-Looking Statements” above for a discussion of the limitations of these forecasts.
