What Tecnoglass Inc. told the SEC could break it.
Tecnoglass's risks center on a cross-border structure: it makes its architectural glass and windows in Colombia but sells about 94.8% into the United States, so U.S. tariffs land directly on it — including a 10% IEEPA ad valorem duty (still subject to litigation) that raises its costs, which it is partly mitigating by shifting to U.S.-cast aluminum, itself a cost increase. Its products are also commodity-intensive — glass, aluminum and vinyl extrusions, ionoplast and PVB — so input-price inflation it can't fully pass through compresses margins. And its raw-material supply is concentrated, with two suppliers together 37.3% of 2025 purchases under agreements terminable on limited notice.
3 self-disclosed vulnerabilities, pulled from its own filings — each in the company’s words, with the source. This is the risk register almost nobody reads.
In its own words
What could break it.
Commodity & input dependence
- Primary manufacturing materials are glass, aluminum and vinyl extrusions, ionoplast and polyvinyl butyral (PVB) — exposed to commodity-price and (for aluminum) tariff-driven cost increasesmedium
Tecnoglass's architectural glass and window products are materials-intensive: its primary manufacturing materials are glass, ionoplast, polyvinyl butyral (PVB), and aluminum and vinyl extrusions. Prices for these inputs — especially aluminum (whose cost rose in part due to its U.S.-cast-aluminum tariff-mitigation strategy) and float glass — directly affect cost of goods and margins. Sustained commodity inflation that it cannot fully offset through pricing would compress profitability. A specific glass/aluminum/PVB commodity dependence.
“Our primary manufacturing materials include glass, ionoplast, polyvinyl butyral, and aluminum and vinyl extrusions.”
Regulatory & policy
- Cross-border tariff exposure — all primary manufacturing in Colombia while ~94.8% of sales are to the U.S.; IEEPA 10% ad valorem duty directly raises costs; shifting to U.S.-cast aluminum to mitigatemedium
Tecnoglass has a structural cross-border tariff exposure: its primary manufacturing facilities are in Colombia, yet approximately 94.8% of fiscal 2025 sales were generated in the United States. New U.S. tariffs — including an additional 10% ad valorem duty under IEEPA (subject to litigation/appeals and uncertain scope/duration/refunds) — directly increase its costs and may pressure margins, and retaliatory measures could compound the impact. It has strategically shifted its supply chain to source U.S.-cast aluminum to mitigate part of the impact (which itself raised aluminum costs). A material, realized trade-policy exposure tied to its single-country (Colombia) manufacturing base selling almost entirely into the U.S.
“Given that our primary manufacturing facilities are located in Colombia and approximately 94.8% of our sales for the fiscal year ended December 31, 2025, were generated in the United States, these tariffs directly increase our costs and may pressure our profit margins.”
Supplier concentration
- Two (unnamed) suppliers each provided more than 10% of raw-material purchases — together 37.3% of total raw-material purchases in 2025; supply agreements terminable on limited noticemedium
Tecnoglass has supplier concentration in its raw materials: in 2025, two suppliers each accounted for more than 10% of total raw-material purchases and together represented 37.3% of total raw-material purchases. Its supply agreements are generally terminable by either party on limited notice. A failure, price increase, or loss of either of these two key suppliers could disrupt manufacturing or raise costs (one is likely its Saint-Gobain/Vidrio Andino float-glass JV, captured separately as an edge). Suppliers are not individually named here, so a supplier-concentration/sole-source risk.
“During the year ended December 31, 2025, two suppliers accounted for more than 10% of total raw material purchases, and in aggregate both account for 37.3% of total raw material purchases.”

Saint-Gobain (Vidrio Andino JV)
“In 2019 we entered into a joint venture agreement with Saint-Gobain, a world leader in the production of float glass, a key component of our manufacturing process, whereby we acquired a 25.8% minority ownership interest in Vidrio Andino, a Colombia-based subsidiary of Saint-Gobain.”
