“The Orion team achieved record fourth quarter and full year results, in-line with our communication last month, yet we are not satisfied. Our results could have even beaten our original guidance if demand had not cooled over the course of 2023. Critically we executed our pricing strategy for the 2024 pricing cycle raising prices modestly from the new base we established last year while gaining additional supply lanes particularly in Europe,” said Corning Painter, Orion’s chief executive officer. “Being an essential material, we expect a gradual recovery of specialty and rubber carbon black demand in 2024, but for it to still lag pre-COVID levels. Most importantly, though, we foresee another year of growth with a clear pathway to achieve our long-term goals.”

Jeff Glajch, Orion’s chief financial officer added, “As Corning mentioned, our results continue to improve, with record Adjusted EBITDA in 2023, as well as increased cash flow and cash flow conversion that has enabled further reduction of debt from 2022 to 2.35 times and continued repurchase of stock. As we have now completed our emissions projects, we have much more flexibility to invest in growing the business balanced with providing returns to our shareholders.”

Volume decreased by 30.8 kmt, or 3.2%, to 932.1 kmt, year-over-year reflecting weaker demand across all regions, except China, and in both segments.

Net sales decreased by $137.0 million, or 6.7%, to $1,893.9 million, driven primarily by the pass-through effect of declining oil prices and lower volume in both segments. Those were partially offset by improved contractual pricing.

Gross profit increased by $2.2 million or 0.5%, to $451.0 million, primarily driven by improved contractual pricing, partially offset by lower volume in both segments and lower cogeneration effects due to European electricity prices.

Income from operations increased by $8.2 million or 4.2%, to $205.3 million.

Adjusted EBITDA increased by $20.0 million, or 6.4%, to $332.3 million. The increase was primarily due to improved contractual pricing. Those were partially offset by lower volume and cogeneration effects in both segments.

Outlook

“For full year 2024, we are projecting an Adjusted EBITDA range of $340 million to $360 million, up 5 percent at the midpoint, compared with 2023. Additionally, we are projecting full year 2024 Adjusted Diluted EPS of $2.05 to $2.20, up 9 percent at the midpoint. We expect discretionary cash flow of approximately $160 million to $180 million in 2024. While there are multiple positive trends that we see could affect our results in 2024, our customers remain cautious,” Mr. Painter added. “Despite this we are looking forward to another year of notable growth, our fourth year in a row. It is also tremendous to have the air emission projects behind us.”

Reconciliation of Non-GAAP Financial Measures

We present certain financial measures that are not prepared in accordance with GAAP or the accounting standards of any other jurisdiction and may not be comparable to other similarly titled measures of other companies. For a reconciliation of these non-GAAP financial measures to their nearest comparable GAAP measures, see section Reconciliation of Non-GAAP Financial Measuresbelow.

These non-GAAP measures include, but are not limited to, Gross profit per metric ton, Adjusted EBITDA, Net Working Capital, Capital Expenditures, Segment Adjusted EBITDA Margin (in percentage), Net debt and Net leverage.

We define Gross profit per metric ton as Gross profit divided by volume measured in metric tons. We define Adjusted EBITDA as Income from operations before depreciation and amortization, stock-based compensation, and non-recurring items (such as, restructuring expenses, legal settlement gain, etc.) plus Earnings in affiliated companies, net of tax. We definite Net Working Capital as Inventories, net plus Accounts receivable, net minus Accounts payable. We define Capital Expenditures as Cash paid for the acquisition of intangible assets and property, plant and equipment. We define Segment Adjusted EBITDA Margin (in percentage) as Segment Adjusted EBITDA divided by segment revenue. We define Net debt as Total debt per Consolidated Balance Sheets plus Deferred debt issuance cost - Term loans minus Cash and cash equivalents. We define Net leverage as Net debt divided by trailing twelve month Adjusted EBITDA.

Adjusted EBITDA is used by our chief operating decision maker (“CODM”) to evaluate our operating performance and to make decisions regarding allocation of capital, because it excludes the effects of items that have less bearing on the performance of our underlying core business. We use this measure, together with other measures of performance under GAAP, to compare the relative performance of operations in planning, budgeting and reviewing our business. By eliminating potential differences in results of operations between periods caused by factors such as depreciation and amortization, historic cost and age of assets, financing and capital structures and taxation positions or regimes, we believe that Adjusted EBITDA provides a useful additional basis for evaluating and comparing the current performance of the underlying operations.

We believe our non-GAAP measures are useful measures of financial performance in addition to Net income, Income from operations and other profitability measures under GAAP, because they facilitate operating performance comparisons from period to period. In addition, we believe these non-GAAP measures aid investors by providing additional insight into our operational performance and help clarify trends affecting our business.

Other companies and analysts may calculate non-GAAP financial measures differently, so making comparisons among companies on this basis should be done carefully. Non-GAAP measures are not performance measures under GAAP and should not be considered in isolation or construed as substitutes for Net sales, Net income, Income from operations, Gross profit and other GAAP measures as an indicator of our operations in accordance with GAAP.

With respect to Adjusted EBITDA and Adjusted Diluted EPS outlook for 2024, we are not able to reconcile the forward-looking non-GAAP financial measures to the closest corresponding GAAP measure without unreasonable efforts because we are unable to predict the ultimate outcome of certain significant items. These items include, but are not limited to, significant legal settlements, tax and regulatory reserve changes, restructuring costs and acquisition and financing related impacts.
