Bill Zarkalis, President and Chief Executive Officer, commented, “In a construction materials market affected by soft demand and economic uncertainty, Titan America delivered all time high revenue, Net Income, Adjusted EBITDA and operating cash flow in 2025. This achievement reflects the strength of our business model, disciplined decision-making, skillful execution across our operations, and an unwavering focus on serving our customers. It showcases once again Titan America’s ability to grow organically and deliver strong results, even in challenging environments. Our Florida segment delivered a robust performance with strong penetration in infrastructure and private non-residential construction segments offsetting a soft residential end-market. Our investments in increased aggregates capacity, expanded capabilities, and self-help operational excellence initiatives delivered record full year revenue and Adjusted EBITDA in 2025. Our Mid-Atlantic segment was impacted by a combination of soft demand in Metro New York and New Jersey, the introduction of tariffs, and weather affecting Virginia and the Carolinas. Resilient pricing, and continued growth in infrastructure, private non-residential construction, including data centers, and cost containment initiatives partially mitigated the impact from the headwinds in the region.”

Revenue for the three months ended December 31, 2025 was $405.7 million, an increase of 4.1% from $389.8 million in the prior year quarter. Revenues were positively impacted by increased aggregates production capacity, cement volumes and ready-mix concrete volumes compared to Q4 2024.

Net Income for the three months ended December 31, 2025 was $43.5 million, an increase of 19.1% from $36.5 million in the prior year quarter, while Adjusted EBITDA was $93.7 million, an increase of 12.2% from $83.5 million in the prior year period. The increase in both Net Income and Adjusted EBITDA was primarily driven by increased revenue, sales mix and improved margins from lower costs and improved productivity. The increase in Net Income was also driven by lower financing costs and reduced impacts from foreign exchange and related derivatives, partially offset by higher general and administrative expenses. Net Income Margin and Adjusted EBITDA Margin in the three months ended December 31, 2025 were 10.7% and 23.1%, respectively, up from 9.4% and 21.4%, respectively, in the same period of 2024.

Revenue for the full year 2025 was $1.66 billion, an increase of 1.8% compared to $1.63 billion in 2024, primarily as a result of increases in product pricing for aggregates and ready-mix concrete and an increase in aggregates sales volumes, partially offset by decreases in sales volumes for cement and concrete block.

Net Income for the full year 2025 was $185.4 million, an increase of 11.7% compared to $166.1 million in 2024, while Adjusted EBITDA was $389.7 million, an increase of 5.2% compared to $370.4 million in 2024. The increase in both Net Income and Adjusted EBITDA was primarily driven by improved margins from lower costs. Net Income also benefitted from lower financing costs and a lower effective tax rate. Net Income Margin and Adjusted EBITDA Margin for the full year 2025 were 11.1% and 23.4%, respectively, compared to 10.2% and 22.7%, respectively, for the full year 2024.

For the twelve months ended December 31, 2025, cash flow provided by operations was $295.4 million, and net capital expenditures were $163.3 million, resulting in free cash flow of $132.1 million.

As of December 31, 2025, Titan America had $211.8 million in cash and cash equivalents and $462.4 million total debt. Net debt was $250.7 million, representing a ratio of 0.64x 2025 Adjusted EBITDA.

The Florida segment generated revenues of $247.1 million in the fourth quarter of 2025, compared to $235.2 million in the prior year quarter. The 5.1% year-over-year increase was primarily due to higher aggregates, concrete block and cement sales volumes due to our strong presence in the infrastructure and private non-residential sectors, and increased aggregates production capacity. Segment adjusted EBITDA for the quarter increased to $64.6 million, compared to $52.7 million in the prior year quarter, primarily due to the impact of higher sales volumes and operational efficiencies.

The Mid-Atlantic segment generated revenues of $158.6 million in the fourth quarter, compared to $153.9 million in the prior year quarter. The 3.0% year-over-year increase in revenue was driven by higher prices as compared to the prior year quarter. Segment adjusted EBITDA was $32.4 million, compared to $34.3 million in the prior year quarter, primarily due to higher cost of goods sold for ready-mix concrete and cement.

The Florida segment generated revenues of $1,024.4 million, reflecting a 2.7% increase from $997.6 million in 2024. Growth was driven by increases in the aggregates, ready-mix concrete and fly ash product lines due to increased aggregates production capacity, an increase in fly ash volumes and higher average price for ready-mix concrete and fly ash. Segment adjusted EBITDA increased 11.6% to $278.7 million from $249.7 million in the prior year, primarily due to the increase in revenue and lower production costs which offset higher general and administrative expenses.

The Mid-Atlantic segment generated revenues of $639.8 million, reflecting a 0.8% increase from $634.9 million in 2024. Growth was driven by increases in the ready-mix concrete and fly ash product lines partially offset by lower cement revenue. Segment adjusted EBITDA was $120.5 million in 2025 as compared to $134.8 million in the prior year, primarily due to lower cement sales volume, increases in raw material unit costs in the ready-mix concrete product line, tariffs on imported cement and higher general and administrative expenses.

Regarding Titan America’s outlook, President & CEO Bill Zarkalis stated, “In 2026, we expect softness in the residential sector to continue. The recent surge in oil and energy prices introduces additional risks in an already complex and uncertain economic backdrop. Based on current market dynamics, with concerns of additional inflation fueled by higher energy costs, we believe mortgage rates are likely to remain broadly at current elevated levels with house affordability remaining low. As a result, we believe investment in the residential sector may be stabilizing at current lower levels with the much anticipated residential sector inflection point being potentially pushed into 2027. With continued residential softness in mind, our guidance for 2026, on a like-for-like basis, anticipates low single digit revenue growth compared to 2025, with modest expansion in our Adjusted EBITDA margins.”

Mr. Zarkalis continued, “Robust operating cash flows and a strong balance sheet reinforce our capacity to act on strategic opportunities including, for example, our recently announced acquisition of the Keystone Cement Company in Pennsylvania. The proposed acquisition, subject to regulatory approval, will expand our geographic footprint, add substantial domestic cement production capacity to our portfolio, and strengthen our presence in the Mid-Atlantic region.”

Mr. Zarkalis concluded, “As we look to 2026 and beyond, we are excited about the strong growth opportunities ahead. The markets where we operate are the beneficiaries of significant tailwinds, including infrastructure investments, manufacturing reshoring and emerging trends in resilient urbanization and construction technology. We continue to execute on our strategic plan - innovating and expanding our product offerings, particularly focusing on meeting the evolving needs of our customers for sustainable, high-performance products, services and solutions.”

In addition to the financial information presented in accordance with International Financial Reporting Standards (“IFRS”), this press release includes the following Non-IFRS financial measures: Adjusted EBITDA, Adjusted EBITDA Margin, Net Income Margin, free cash flow, net debt and the ratio of net debt to Adjusted EBITDA. We define Adjusted EBITDA as net income before finance cost, net, income tax expense, depreciation, depletion and amortization, further adjusted to remove the impact of additional items such as (gain)/loss on disposal of fixed assets, asset impairment (recovery)/loss, foreign exchange (gain)/loss, net, derivative financial instrument (gain)/loss, net, fair value loss on sale of accounts receivable, net, share-based compensation and other non-recurring items, including certain transaction costs related to our initial public offering and merger and acquisition costs. We define Adjusted EBITDA Margin as Adjusted EBITDA divided by revenues. We define Net Income Margin as net income divided by revenue. We define free cash flow as net cash provided by operating activities, less net payments for capital expenditures, which includes (i) investments in property, plant and equipment, (ii) investments in identifiable intangible assets and (iii) proceeds from the sale of assets, net of disposition costs. We define net debt as the sum of short and long-term borrowings, including accrued interest and short-term and long-term lease liabilities less cash and cash equivalents. We define the ratio of net debt to Adjusted EBITDA as the ratio derived by dividing net debt by Adjusted EBITDA. See “Reconciliation of IFRS to Non-IFRS” section for a detailed reconciliation of Non-IFRS financial measures to the most directly comparable IFRS measure.

We believe that in addition to our results determined in accordance with IFRS, these Non-IFRS financial measures provide useful information to both management and investors in measuring our financial performance and highlight trends in our business that may not otherwise be apparent when relying solely on IFRS measures.

Non-IFRS financial information is presented for supplemental informational purposes only and should not be considered in isolation or as a substitute for financial information presented in accordance with IFRS. Our presentation of Non-IFRS measures should not be construed as an inference that our future results will be unaffected by unusual or nonrecurring items. Other companies in our industry may calculate these measures differently, which may limit their usefulness as comparative measures.

(1)Net Income Margin is calculated as net income divided by revenues.

(2)Adjusted EBITDA Margin is calculated as Adjusted EBITDA divided by revenues.
