Miami, FL – November 5, 2026 – Tecnoglass Holdings Inc. (NYSE: TGLS) (“Tecnoglass” or the “Company”), a leading producer of high-end aluminum and vinyl windows and architectural glass for the global residential and commercial end markets, today reported financial results for the third quarter ended September 30, 2026.

José Manuel Daes, Chief Executive Officer of Tecnoglass, commented, “We were pleased to deliver record revenues in the third quarter, up 19% year-over-year, led by 31% growth in our multi-family and commercial business. Single-family residential revenues grew 17% year-over-year excluding the previously disclosed pre-buy activity in the second quarter, reflecting continued market share gains as we expand outside of Florida. Third quarter margins were pressured by costs outside of our control, including elevated aluminum costs, ongoing tariffs and a Colombian Peso at its strongest level since 2018. Our higher volumes in the quarter drew on aluminum purchased at peak prices earlier in the year, and we have since secured aluminum at lower levels. Excluding an $8.4 million non-cash inventory revaluation tied to a rapid rise in the Peso, Adjusted EBITDA for the quarter was actually ahead of our internal expectations given a very strong top line performance. The benefits of our May pricing actions are beginning to flow through single-family residential invoicing, and our automation initiatives are taking hold, which position us well to deliver improved profitability. Together, these actions are making us a stronger and more efficient company, and we remain confident in our ability to unlock additional value for our shareholders.”

Christian Daes, Chief Operating Officer of Tecnoglass, added, “Our backlog reached another record of $1.43 billion, extending our track record of sequential growth since 2021 and reflecting consistent execution on a growing pipeline of multi-family and commercial projects. We continued to book large projects within the luxury lodging and condo market, and subsequent to quarter end signed our largest project to date, which continues to provide strong visibility for the next few years. Our May pricing will reach multi-family and commercial revenue as projects booked after the increase move through our backlog, starting with shorter-cycle jobs late this year and larger projects during 2027. In single-family residential projects, our expanding dealer network, vinyl lines and geographic diversification continue to support market share gains, and our recently opened Los Angeles showroom is bringing our Legacy Line to the West Coast. Across both businesses, our differentiated product portfolio, expanding geographic reach, and strong project pipeline position us well to keep gaining share as we move into 2027.”

Third Quarter 2026 Results

Total revenues for the third quarter of 2026 increased 19.2% to a record $310.6 million, compared to $260.5 million in the prior year quarter. Multi-family/commercial revenues grew 30.9% year-over-year to a record $192.4 million, driven by execution on a record backlog as projects moved into more advanced stages. Single-family residential revenues grew 4.1% year-over-year to $118.1 million, reflecting continued market share gains, geographic expansion and pricing actions, partially offset by the timing of orders placed in the second quarter ahead of the Company’s May pricing actions. Changes in foreign currency exchange rates represented a $2.4 million benefit to total revenues in the quarter.

Gross profit for the third quarter was $106.0 million, or a 34.1% gross margin, compared to $111.3 million, or a 42.7% gross margin in the prior year quarter. A stronger Colombian Peso, which appreciated approximately 20% year-over-year and 12% sequentially, drove approximately 580 basis points of the 860 basis point decline. Roughly 250 basis points   of that FX impact was a non-cash inventory revaluation of approximately $8.4 million. That inventory was bought when the Peso was weaker and sold after it strengthened, which increased its reported cost without any cash impact. Gross margin also reflected higher raw material costs from U.S. aluminum purchased at peak prices earlier in the year, an unfavorable mix from a higher level of installation revenue, and higher labor costs related to the annual minimum wage adjustment in Colombia at the beginning of the year. These impacts were partly offset by operating leverage on higher volume, pricing actions implemented in May that began converting into revenue during the quarter, and efficiencies from the Company’s automation initiatives. Excluding that non-cash effect, gross margin was roughly in line with the second quarter of 2026.

Selling, general and administrative expense (“SG&A”) was $74.0 million for the third quarter of 2026 compared to $47.3 million in the prior year quarter. The increase primarily reflected approximately $15.5 million   of expenses associated with Section 232 tariffs on finished aluminum window imports, along with higher transportation and commission expenses associated with revenue growth in the quarter and a stronger Colombian Peso. As a percent of total revenues, SG&A was 23.8% for the third quarter of 2026 compared to 18.2% in the prior year quarter, primarily due to the aforementioned factors.

Net income was $22.8 million, or $0.51 per diluted share, in the third quarter of 2026 compared to net income of $47.2 million, or $1.01 per diluted share, in the prior year quarter, including a non-cash foreign exchange transaction loss of $3.3 million  in the third quarter of 2026 and a gain of $1.9 million in the third quarter of 2025. These non-cash gains and losses relate to the accounting re-measurement of U.S. Dollar-denominated assets and liabilities against the Colombian Peso as the functional currency.

Adjusted net income¹ was $27.3 million, or $0.61 per diluted share, in the third quarter of 2026 compared to adjusted net income¹ of $46.7 million, or $1.00 per diluted share, in the prior year quarter. Adjusted net income¹, as reconciled in the table below, excludes the impact of non-cash foreign exchange transaction gains or losses, the non-cash mark-to-market of certain derivative transactions, and other non-core items, along with the tax impact of adjustments at statutory rates, which management believes better reflects core financial performance.

Adjusted EBITDA¹, as reconciled in the table below, was $47.7 million, or 15.3% of total revenues, in the third quarter of 2026, compared to $79.1 million, or 30.4% of total revenues, in the prior year quarter. The change was primarily attributable to the factors impacting gross margin and SG&A. Adjusted EBITDA would have been approximately $8.4 million higher excluding the non-cash inventory revaluation.

Cash Generation, Capital Allocation and Liquidity

Cash provided by operating activities for the third quarter of 2026 was approximately $21.5 million, reflecting working capital contributions from trade receivables and inventories and lower income tax payments than in the second quarter  . Capital expenditures of approximately $66.1 million in the quarter included several previously announced investments, including the purchase of land for the potential U.S. facility, and scheduled payments related to capacity enhancements and ongoing automation initiatives. In August, the Company completed the previously announced $23 million purchase of land in St. Lucie County, Florida, to preserve strategic flexibility for a potential new state-of-the-art manufacturing facility. The feasibility study for the potential new facility remains active and does not represent a commitment to proceed with construction, which would occur in phases based on factors such as demand, market conditions and return profiles. The Company has secured state, local and utility incentives that, should the project meet its parameters, are expected to significantly enhance the estimated returns of the potential project.

During the quarter, the Company returned capital to shareholders through $6.7 million in cash dividends. As of September 30, 2026, the Company had approximately $92.5 million remaining under its current share repurchase program.

The Company ended the third quarter of 2026 with total liquidity of approximately $380 million  , including $97.7 million of cash and cash equivalents and $280 million of availability under its revolving credit facilities, and total debt of $293.6 million. The Company maintains a conservative leverage profile of approximately 0.9x net debt to LTM Adjusted EBITDA¹, providing significant financial flexibility to continue investing in growth initiatives and returning capital to shareholders.

Full Year 2026 Guidance

Santiago Giraldo, Chief Financial Officer of Tecnoglass, stated, “Based on our performance year to date and the visibility provided by our order book, we are raising our full year 2026 revenue outlook to a range of $1.10 billion to $1.14 billion  and adjusting our Adjusted EBITDA outlook to a range of $210 million to $220 million. The change in our Adjusted EBITDA outlook mainly reflects the approximately $8.4 million non-cash inventory revaluation in the third quarter. Excluding that effect, our Adjusted EBITDA outlook would have been approximately $8.4 million higher. Higher than expected revenues are helping offset elevated raw material costs and a stronger Colombian Peso. We remain encouraged by demand trends and by our ability to grow well above industry rates. Looking ahead, we are committed to fully offsetting the impact of tariffs in 2027, as automation savings and full-year pricing are realized. With a conservative debt leverage profile and strong cash generation, we remain well-positioned to invest in growth while returning capital to shareholders.”

Reconciliation of Non-GAAP Performance Measures to GAAP Performance Measures

(In thousands)

(Unaudited)

The Company believes that total revenues with foreign currency held neutral, which are not performance measures under generally accepted accounting principles (“GAAP”), may provide users of the Company’s financial information with additional meaningful bases for comparing the Company’s current results and results in a prior period, as these measures reflect factors that are unique to one period relative to the comparable period. Management uses such performance measures in managing and evaluating the Company’s business. However, these non-GAAP performance measures should be viewed in addition to, and not as an alternative for, the Company’s reported results under accounting principles generally accepted in the United States.

Currency impacts on total revenues for the current quarter have been derived by translating current quarter revenues at the prevailing average foreign currency rates during the prior year quarter, as applicable.

Reconciliation of Adjusted EBITDA and Adjusted net (loss) income to net (loss) income

(In thousands, except share and per share data) / (Unaudited)

Adjusted EBITDA and adjusted net (loss) income are non-GAAP performance measures. Management believes Adjusted EBITDA and adjusted net (loss) income, in addition to operating profit, net (loss) income and other GAAP measures, are useful to investors to evaluate the Company’s results because they exclude certain items that are not directly related to the Company’s core operating performance. Investors should recognize that Adjusted EBITDA and adjusted net (loss) income might not be comparable to similarly-titled measures of other companies. These measures should be considered in addition to, and not as a substitute for or superior to, any measure of performance prepared in accordance with GAAP.

Reconciliations of the non-GAAP measures used in this press release are included in the tables attached to this press release, to the extent available without unreasonable effort. Because GAAP financial measures on a forward-looking basis are not accessible, and reconciling information is not available without unreasonable effort, we have not provided reconciliations for forward-looking non-GAAP measures. Items excluded to arrive at forward-looking non-GAAP measures may have a significant, and potentially unpredictable, impact on our future GAAP results.
