BARRANQUILLA, Colombia – November 8, 2021 – Tecnoglass, Inc. (NASDAQ: TGLS) (“Tecnoglass” or the “Company”), a leading manufacturer of architectural glass, windows, and associated aluminum products serving the global residential and commercial end markets, today reported financial results for the third quarter ended September 30, 2021.

José Manuel Daes, Chief Executive Officer of Tecnoglass, commented, “I could not be more proud of our exceptional third quarter performance that marked our 4^th consecutive quarter of year-over-year revenue growth and another period of record quarterly revenues and adjusted EBITDA. In addition, continued momentum in our U.S. single-family residential business combined with careful working capital management collectively helped generate our 7^th straight quarter of robust cash flow, allowing us to pay down debt while further investing in automation capabilities and capacity enhancements to address expected growth. As a result of our vertically integrated platform and strategic geographic positioning, we continue to enjoy a healthy competitive advantage that has mostly insulated Tecnoglass thus far from widespread supply chain disruptions and inflationary pressures affecting our industry. Our structural advantages have allowed us to achieve additional share gains as new and existing customers value our shorter lead times, continuity of product availability and unrelenting commitment to exceptional service. We expect to continue executing our highly profitable growth strategy and generating cash flow to deliver additional value for our shareholders.”

Christian Daes, Chief Operating Officer of Tecnoglass, added, “Our proven track record of innovation, strategic footprint expansion, and returns-oriented investments in our operations have distinguished Tecnoglass as a dominant player in the architectural glass market with industry-leading margins. During the third quarter, we were pleased to begin invoicing best-in-class products from our new Multimax product line targeting production homebuilders as well as legacy and new dealers, which further augments our positioning in the U.S. single-family residential market. Additionally, we are encouraged to report a record backlog at quarter end which reflects an increasing number of commercial projects in our pipeline through 2022. As we move forward, we are very pleased with our project pipeline and are excited by the strong momentum in our single-family residential business where we continue to see an immense opportunity for growth and additional share gains. Our strong geographical positioning, innovative product portfolio, and unique vertically integrated model give us confidence in the trajectory of our business.”

Third Quarter 2021 Results

Total revenues for the third quarter of 2021 increased 26.2% to $130.4 million, compared to $103.3 million in the prior year quarter. U.S. revenues of $123.2 million, which represented 94.5% of total revenues, grew 28.8% compared to $95.7 million in the prior year quarter, driven by strong growth in single family residential activity and market share gains. Latam revenue, a majority of which is represented by long-term contracts priced in Colombian Pesos but indexed to the U.S. Dollar, decreased slightly to $7.2 million, compared to $7.6 million in the prior year quarter. Changes in foreign currency exchange rates had a negligible impact on Colombia and total revenues in the quarter.

Gross profit for the third quarter of 2021 grew 28.7% to $51.6 million, representing a 39.6% gross margin, compared to gross profit of $40.1 million, representing a 38.8% gross margin in the prior year quarter. The 80 basis point improvement in gross margin mainly reflected greater operating efficiencies and a higher mix of revenue from manufacturing versus installation activity as Tecnoglass increased its mix of single family residential products. Selling, general and administrative expense (“SG&A”) was $21.5 million compared to $19.9 million in the prior year quarter, primarily attributable to higher variable expenses related to ground and marine transportation as well as commission expenses. As a percent of total revenues, SG&A improved to 16.5% compared to 19.3% in the prior year quarter, primarily due to higher sales and better operating leverage on personnel, professional fees and other fixed expenses.

Net income was $20.9 million, or $0.44 per diluted share, in the third quarter of 2021 compared to net income of $8.3 million, or $0.18 per diluted share in the prior year quarter, including an after-tax non-cash foreign exchange transaction gain of $0.2 million in the third quarter of 2021 and a $3.1 million loss in the third quarter of 2020. As previously disclosed, these non-cash gains and losses are related to the accounting re-measurement of U.S. Dollar denominated assets and liabilities against the Colombian Peso as functional currency.

Adjusted net income¹ was $21.6 million, or $0.45 per diluted share, in the third quarter of 2021 compared to adjusted net income of $12.7 million, or $0.28 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 and other non-core items, along with the tax impact of adjustments at statutory rates, to better reflect core financial performance.

Adjusted EBITDA¹, as reconciled in the table below, increased 36.1% to $38.7 million, or 29.7% of total revenues in the third quarter of 2021, compared to $28.5 million, or 27.5% of total revenues in the prior year quarter. The improvement was driven by higher sales, a stronger gross margin and operating leverage on SG&A. Adjusted EBITDA¹ in the third quarter 2021 included $0.8 million in contribution from the Company’s joint venture with Saint-Gobain, compared to $0.7 million in the prior year quarter.

Dividend

The Company declared a quarterly cash dividend of $0.0275 per share for the third quarter of 2021, which was paid on October 29, 2021 to shareholders of record as of the close of business on September 30, 2021.

Balance Sheet & Liquidity

The Company ended the third quarter of 2021 with total liquidity of approximately $150 million, including cash and cash equivalents of $86.5 million and availability under its committed revolving credit facilities of $65 million. Cash provided by operating activities of $32.6 million improved by $6.4 million compared to the prior year quarter, attributable to higher profitability as well as more efficient inventory and working capital management. Given the Company’s continued growth in adjusted EBITDA¹ and strong cash generation, debt leverage continues to trend lower and now stands at 0.9 times LTM net debt to adjusted EBITDA¹, compared to 1.9 times in the prior year quarter. Given its strong cashflow generation, the Company voluntarily prepaid $30 million under its Syndicated Term Loan facility during the quarter.

Full Year 2021 Outlook

Santiago Giraldo, Chief Financial Officer of Tecnoglass, stated, “Based on our strong third quarter performance and expectations for a favorable growth environment across our end markets through year-end, we are increasing our full year 2021 growth outlook for revenues and adjusted EBITDA¹. We now expect 2021 revenues to grow to a range of $485 million to $495 million. We now anticipate full year adjusted EBITDA¹ to increase to a range of $140 million to $145 million, implying year-over-year growth of approximately 46% at the midpoint. We continue to expect that robust demand for our products and services in the U.S. will be the primary driver of these anticipated record full year 2021 results.”

Reconciliation of Non-GAAP Performance Measures to GAAP Performance Measures

(In thousands)

(Unaudited)

The Company believes that total revenues with foreign currency held neutral non-GAAP performance measures, which management uses in managing and evaluating the Company’s business, 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. 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 not measures of financial performance under generally accepted accounting principles (“GAAP”). Management believes Adjusted EBITDA and adjusted net (loss) income, in addition to operating profit, net (loss) income and other GAAP measures, is useful to investors to evaluate the Company’s results because it excludes 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.
