Tecnoglass (TGLS) Q3 2026 earnings review
Tecnoglass sales hit a record, but peso and tariffs cut profit
Tecnoglass, a Colombian maker of architectural glass and windows, is growing sales fast while import tariffs and currency moves squeeze its profit. Revenue rose 19% to a record $311 million on commercial building projects, far above what the company's own plan pointed to. However, a 20% stronger Colombian peso and $16 million in U.S. aluminum window tariffs cut operating cash profit by 40%, and finance chief Santiago Giraldo lowered the full-year profit outlook for a third time.
| Revenue | $310.6M +19.2% from a year ago |
|---|---|
| Single-family sales (excluding Q2 early orders) | +17% +4.1% as reported |
| Gross margin | 34.1% -8.6 percentage points from a year ago |
| Full-year Adjusted EBITDA outlook | Cut $10M middle of the range: $215M (-26% vs 2025) |
⚖️ Verdict: 🔴 Bearish
The story got worse because record sales and May price increases still could not stop a sixth straight drop in gross margin or a third cut to the profit plan. Even removing an $8 million non-cash inventory charge caused by the stronger peso, gross margin slipped again and heavy factory and land spending pushed total debt up to $294 million. The bright spot is demand: home-window sales grew 17% excluding spring's early orders, and backlog reached $1.43 billion.
The question now is whether current cost pressures are a temporary timing gap or a lasting loss of the company's Colombian cost advantage. Either cheaper aluminum and 2027 commercial contract repricing will restore margins next year, or a strong peso and U.S. tariffs will keep profitability near 20% of sales. Fourth-quarter gross margin and the 2027 outlook will tell.
🐂 Bull Case
Commercial Projects and West Coast Expansion Lifted Sales 19%
Tecnoglass makes architectural glass and aluminum and vinyl windows for apartment buildings, offices and homes, with the United States providing 95% of its sales. Total revenue grew 19.2% from a year ago to a record $310.6 million, beating the roughly $280 million finance chief Santiago Giraldo indicated last quarter.
- Multi-family and commercial revenue: $192.4 million, up 30.9% from a year ago
- Single-family residential revenue: $118.1 million, up 4.1% as reported, or 17% excluding orders customers placed early in Q2 ahead of May price increases
- Order backlog: a record $1.43 billion, up 13.2% from a year ago and $50 million from last quarter by our math
The results ease concern that April's early ordering would leave a hole in home-window demand. The window maker also opened its delayed Los Angeles showroom to sell its Legacy Line aluminum windows on the West Coast, and chief operating officer Christian Daes said it "subsequent to quarter end signed our largest project to date".
What to watch: single-family residential revenue in Q4 without any early-order distortion. Double-digit growth would confirm that new dealers outside Florida are driving steady market share gains.
🐻 Bear Case
A Stronger Colombian Peso Cut Profit Outlook Again
Tecnoglass manufactures its windows in Barranquilla, Colombia, and sells almost all of them in U.S. dollars, so a rising Colombian peso inflates its local factory and labor costs. Chief executive José Manuel Daes noted that "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".
The peso rose about 20% from a year ago and 12% from last quarter, taking 5.8 percentage points off gross margin. About 2.5 points of that drop came because Tecnoglass bought raw materials when the peso was weaker and sold the finished windows after the currency strengthened.
Calling the $8.4 million charge non-cash does not make the currency problem a one-off. Even without that charge, Giraldo cut the full-year Adjusted EBITDA (operating cash profit before interest, taxes and depreciation) outlook for a third time this year, to $210–220 million. By our math, the outlook implies Q4 Adjusted EBITDA of about $54 million, down 13% from a year ago despite 8% implied revenue growth.
What to watch: Q4 gross margin if the Colombian peso stays near its eight-year high. Another drop in cash operating profit would show that ongoing factory wages and local overhead hurt earnings long after the inventory adjustment passes.
May Price Increases and Automation Have Not Stopped the Margin Slide
Since the U.S. placed 10% Section 232 import tariffs on finished aluminum windows in April, Tecnoglass has raised single-family prices and automated factory lines to protect profits. Those steps are both a potential profit driver and an execution risk, and this quarter the costs moved faster than the offsets.
- Gross margin: 34.1%, down 8.6 percentage points from a year ago (36.8% excluding the inventory charge by our math, down from 37.3% in Q2)
- Cost of sales (cost of making and installing windows): 65.9% of revenue, up 8.6 percentage points from a year ago
- Selling, general and administrative expense (shipping, tariffs, commissions and overhead): 23.8% of revenue, up 5.7 percentage points, including $15.5 million in tariffs
Gross margin has now fallen for six straight quarters. Daes said Q3 volumes used aluminum bought at peak prices earlier in the year and the group "have since secured aluminum at lower levels". Still, Christian Daes noted that May price increases will reach commercial backlog only gradually, "starting with shorter-cycle jobs late this year and larger projects during 2027", which is why Giraldo aims to fully offset tariffs only in 2027.
What to watch: Section 232 tariff expense against gross margin in Q4. A rebound toward 38% gross margin would show cheaper aluminum and commercial repricing are finally catching up with the $15.5 million quarterly tariff bill.
Capital Spending Drained Cash and Raised Debt to $294 Million
Tecnoglass is spending heavily on factory automation and U.S. expansion while its operating cash flow is down from last year. In August, it completed a $23 million land purchase in St. Lucie County, Florida "to preserve strategic flexibility for a potential new state-of-the-art manufacturing facility", though its feasibility study continues with no commitment to build.
Operating cash flow improved to $21.5 million in Q3, up from $4.4 million in Q2 on lower tax payments. However, capital expenditures reached $66.1 million, leaving negative free cash flow of $44.5 million for the quarter by our math and pushing total debt up 71% this year to $293.6 million. Because of the cash drain, management kept share buybacks paused in Q3.
What to watch: Q4 capital expenditures and the decision on the Florida plant in early 2027. Full-year capital spending has already reached $118.7 million in nine months, well above the $80–95 million plan discussed last quarter.
Risks this quarter didn't answer
Five standing watch items and concerns are not readable from the earnings release and await the conference call or quarterly filing.
- Florida share of backlog: not in the release; the call commentary will show if it fell below last quarter's roughly 75%.
- Firm orders versus headline backlog: the 10-Q filing's remaining performance obligations note will show how much of the $1.43 billion backlog is signed contracts rather than letters of intent.
- Book-to-bill ratio (new orders divided by billed sales): omitted from the release after printing 1.1x in Q2.
- Vinyl window revenue: mentioned qualitatively as supporting share gains, with no dollar figure against the prior $5 million monthly target.
- Related-party transactions: the 10-Q footnote will update purchases and sales with entities owned by the founding Daes family.
💲 Other KPIs
Working capital growth slowed in Q3 after absorbing heavy cash in the first half. Inventories stood at $274.9 million, up 28.7% from December 2025 but up only 1.2% from Q2 by our math, while trade receivables — money customers owe for delivered windows — edged down from $287.5 million in Q2 to $282.4 million.
Down 5.3% from 46.8 million a year ago due to late-2025 and Q1 buybacks, but unchanged from Q2. The glass maker spent almost nothing on share repurchases in Q3 by our math, keeping $92.5 million left under its repurchase authorization while funding $6.7 million in cash dividends.
🔮 Guidance
Raised. Finance chief Santiago Giraldo lifted the middle of the full-year sales range by $20 million to $1.12 billion, or 13.9% growth from 2025 by our math. Because Q3 beat by $31 million, that leaves about $265 million for Q4 by our math, slowing growth to 8.1% from 19.2% in Q3 despite an easy prior-year comparison. It is the second raise this year (+$5M, +$20M).
Cut. The middle of the operating cash profit plan dropped by $10 million to $215 million, down 26.2% from 2025 by our math, mainly reflecting Q3's $8.4 million peso inventory charge. By our math, the outlook leaves about $54.1 million for Q4 (down 13.1% from a year ago, though up from $47.7 million in Q3). It is the third cut this year: -$50M, -$10M, -$10M.
❓ Key Questions
Why Did Nine-Month Capital Spending Exceed the Full-Year Plan?
Nine-month capital expenditures reached $118.7 million, including $66.1 million in Q3 alone, surpassing the $80–95 million full-year range (which already included the $23 million Florida land purchase) discussed last quarter. What drove the extra $24–39 million in spending, and what is the Q4 budget?
What Share of the $1.43 Billion Backlog Is Firm Contracts?
Last quarter's filing showed $884.2 million in remaining performance obligations against a $1.38 billion headline backlog. How much of Q3's record $1.43 billion backlog and the newly signed largest project to date sit in binding contracts versus letters of intent?
What Are the Dollar Savings From Automation and Cheaper Aluminum?
Management committed to fully offsetting Section 232 tariffs ($15.5 million in Q3) in 2027 and said it secured cheaper aluminum after Q3 drew on peak-priced inventory. How many basis points of gross margin will lower aluminum costs and factory automation restore in Q4 and 2027?
Where Do Vinyl Sales and Non-Florida Backlog Stand Today?
The release notes that vinyl window lines and geographic expansion supported share gains, but gives no numbers. Did vinyl reach its earlier $5 million monthly target in the second half, and did Florida's share of backlog drop below 75%?
