Titan America Announces Second Quarter 2025 Results - Effectively Navigated Year-over-Year Weather Impacts and a Softer Residential Market - - 2025 Guidance Reaffirmed - Norfolk, Virginia, July 29, 2025 – Titan America SA (NYSE: TTAM), a leading fully-integrated producer and supplier of building materials, services and solutions in the construction industry operating along the U.S. East Coast, today announced its second quarter 2025 financial results. Titan America SA, including its wholly-owned operating subsidiary, Titan America LLC, shall be referred to herein as “Titan America.” Second-Quarter 2025 Highlights • Revenue of $429.2 million, compared to $433.1 million in Q2 2024 • Net Income of $51.1 million, compared to $60.3 million in Q2 2024 • Earnings per share of $0.28, compared to $0.34 in Q2 2024 • Adjusted EBITDA(1) of $99.5 million, compared to $116.8 million in Q2 2024 “We delivered resilient financial performance in the second quarter, demonstrating the strength of our vertically integrated business model in the face of uncertain economic conditions and challenging weather conditions in the Mid-Atlantic region of our country,” said Bill Zarkalis, President & CEO of Titan America. “As expected, our second quarter financial results, when compared to the year ago period, were adversely impacted by the timing of planned major maintenance activities at our Pennsuco cement plant. Looking ahead, we see favorable long-term fundamentals driven by infrastructure investments and resilient urbanization trends along the US Eastern Seaboard - factors that position us well for future growth and enhanced shareholder value.” Second Quarter 2025 Results (unaudited) Three Months Ended June 30 Six Months Ended June 30 2025 2024 $ Change % Change 2025 2024 $ Change % Change (all amounts in thousands of US$) Revenue $ 429,239 $ 433,061 $ (3,822) (0.9) % $ 821,678 $ 833,152 $ (11,474) (1.4) % Net Income $ 51,132 $ 60,319 $ (9,187) (15.2) % $ 84,505 $ 89,851 $ (5,346) (5.9) % Adjusted EBITDA $ 99,459 $ 116,787 $ (17,328) (14.8) % $ 179,243 $ 188,232 $ (8,989) (4.8) % Capital Expenditures $ 49,502 $ 36,175 $ 13,327 36.8 % $ 82,000 $ 63,883 $ 18,117 28.4 % Revenues for the three months ended June 30, 2025 were $429.2 million compared to $433.1 million in the prior year quarter. Revenues were affected primarily by adverse weather conditions in the quarter, especially in the Mid-Atlantic segment, and continued softness in residential markets. Net income for the three months ended June 30, 2025 was $51.1 million compared to $60.3 million in the prior year quarter, while Adjusted EBITDA was $99.5 million compared to $116.8 million in the same periods. The decrease in both net income and Adjusted EBITDA was primarily driven by the timing of planned major maintenance activities at our Pennsuco cement plant and lower demand for construction materials associated with inclement weather and softness in residential end markets. Net Income Margin and Adjusted EBITDA Margin in the three months ended June 30, 2025 were 11.9% and 23.2%, respectively, compared to 13.9% and 27.0%, respectively, in the same period of 2024. Exhibit 99.1

Cash Flow and Capital Resources For the six months ended June 30, 2025, cash flow provided by operations was $108.1 million and capital expenditures, net were $82.0 million, resulting in free cash flow of $26.1 million. As of June 30, 2025, Titan America had $148.8 million in cash and cash equivalents and $471.8 million total debt. Net debt was $323.0 million, representing a ratio of 0.89x trailing twelve-month Adjusted EBITDA.

The 1.2% year-over-year increase was primarily due to higher aggregates volumes, which were partially offset by continued weakness in demand for cement, ready-mix concrete, and concrete block. Segment Adjusted EBITDA for the quarter declined to $62.2 million, compared to $70.9 million in the prior year quarter primarily due to the timing of the annual major maintenance outage at the Pennsuco cement plant. The Mid-Atlantic segment generated revenues of $168.5 million in the second quarter, compared to $175.1 million in the prior year quarter as adverse weather conditions led to lower sales volumes. Segment adjusted EBITDA was $40.6 million, compared to $49.2 million in the prior year quarter primarily due to the impact of lower sales volumes and higher raw material costs. 2

2025 Outlook Regarding Titan America’s outlook, Titan America President & CEO Bill Zarkalis stated, “We are reaffirming our full-year 2025 outlook based on the strength of our order book and an expected return to more normal weather patterns as compared to H2 2024 when our operations were severely impacted by three significant hurricanes. Under this assumption, we expect revenue growth in the mid-single digit percent range, with modest improvement in Adjusted EBITDA margins compared to 2024.” Conference Call Titan America will host a conference call at 5:00 p.m. ET on July 29, 2025.

Financial Measures (Non-IFRS) 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. We define Adjusted EBITDA Margin as Adjusted EBITDA divided by revenues. 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) As used throughout this release, the terms Adjusted EBITDA, Adjusted EBITDA margin, Net Income margin, free cash flow, net debt and net debt to Adjusted EBITDA are non-IFRS financial metrics. See “Reconciliation of IFRS to Non-IFRS” for a detailed reconciliation of Non-IFRS financial measures to the most directly comparable IFRS measure. See “Financial Measures (Non-IFRS)” for further discussion on these non-IFRS measures and why we believe they are useful. 4
