Third Quarter 2020 Highlights

BARRANQUILLA, Colombia – November 6, 2020 – Tecnoglass, Inc. (NASDAQ: TGLS) (“Tecnoglass” or the “Company”), a leading manufacturer of architectural glass, windows, and associated aluminum products for the global residential and commercial construction industries, today reported financial results for the third quarter ended September 30, 2020.

José Manuel Daes, Chief Executive Officer of Tecnoglass, commented, “I could not be more thrilled with the truly outstanding performance of our Company, delivering record year-to-date Adjusted EBITDA of $72.1 million and a solid 500 basis point improvement in Adjusted EBITDA margin year-over-year, all while retaining our entire workforce. The strength of our business carried into the third quarter, demonstrated by record quarterly gross profit, adjusted EBITDA¹ and operating cash flow. Our ability to innovate, adapt and excel allowed us to increase our U.S. revenues, led by growth in single family housing, one of our strongest growth channels. Operationally, we continue to reap the benefits of our previously completed high return automation initiatives, contributing to the expansion of our industry-leading margins, improved cash generation and a quarter end net debt to LTM Adjusted EBITDA ratio below 2.0 times.”

José Manuel Daes continued, “We are extremely pleased that our consortium of mostly U.S. and European based lenders have recognized our record of success, as well as the benefits of our strategically located and vertically-integrated operations. This is reflected in our new $300 million credit facility underwritten on what we believe to be terms comparable to or better than many publicly traded U.S. companies of similar size. For Tecnoglass, 2020 has been a milestone year on many fronts thus far and we plan to continue creating additional value in our business.”

Christian Daes, Chief Operating Officer of Tecnoglass, added, “Our third quarter results reflect a continued recovery in the U.S., particularly in residential, and overall strong demand for our best-in-class architectural glass products. We recently introduced a new product for homebuilders that should help us further expand our addressable market in single family housing beyond renovation projects and outside of hurricane prone markets. Overall market share gains and successful expansion into new U.S. geographies are allowing us to produce growth in a complex environment. As we move to the end of 2020, we are excited by the momentum in our business. We believe our innovative product portfolio, strong industry relationships and structural competitive advantages position us to continue growing faster than our end markets into 2021 and beyond.”

Third Quarter 2020 Results

Total revenues for the third quarter of 2020 were $103.3 million compared to $108.5 million in the prior year quarter. U.S. revenues of $95.7 million, which represented 93% of total revenues, grew 3.1% compared to $92.8 million in the prior year quarter, primarily driven by strong growth in residential activity. The contribution of U.S. revenue growth to total revenues was more than offset by lower revenue from Colombia and other Latin American regions, primarily attributable to delayed activity at many customer job sites due to COVID-19 related factors. Changes in foreign currency exchange rates had an adverse impact of $0.9 million on Colombia and total revenues in the quarter.

Gross profit for the third quarter of 2020 grew 12.3% to $40.1 million, representing a 38.8% gross margin, compared to gross profit of $35.7 million, representing a 33.0% gross margin in the prior year quarter. The 580 basis point improvement in gross margin mainly reflected lower raw material costs, greater operating efficiencies from prior automation initiatives, and a higher mix of revenue from manufacturing versus installation activity. Selling, general and administrative expense (“SG&A”) was $19.9 million compared to $20.2 million in the prior year quarter, primarily attributable to lower variable expenses related to shipping, commissions, and other personnel expenses as well as tight cost controls. As a percent of total revenues, SG&A was 19.3% compared to 18.6% in the prior year quarter due to lower revenues.

Net income was $8.3 million, or $0.18 per diluted share, in the third quarter of 2020 compared to net loss of $1.3 million, or $0.03 loss per diluted share, in the prior year quarter, including an after-tax non-cash foreign exchange transaction loss of $3.1 million in the third quarter 2020 and a $12.0 million loss in the third quarter 2019. As previously disclosed, these 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 $12.7 million, or $0.28 per diluted share, in the third quarter of 2020 compared to adjusted a net income of $8.3 million, or $0.18 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, was $28.5 million, or 27.5% of total revenues in the third quarter of 2020, compared to $24.0 million, or 22.1% of revenues, in the prior year quarter. The increase was driven by stronger gross margin. Adjusted EBITDA¹ in the third quarter 2020 included $0.7 million in contribution from the Company’s joint venture with Saint-Gobain, compared to $0.9 million in the prior year quarter.

Dividend

The Company declared a quarterly cash dividend of $0.0275 per share for the third quarter of 2020, which was paid on October 30, 2020 to shareholders of record as of the close of business on September 30, 2020.

Balance Sheet & Liquidity

On November 2, 2020, Tecnoglass announced a new $300 million Senior Secured Credit Facility, consisting of a $250 million delayed draw term loan and a $50 million committed revolving credit facility, with a maturity date in 2025. The new facility has an initial interest rate spread of 3.00%, which the Company expects to decrease to a spread of 2.75% in April 2021.

The Company intends to use the net proceeds to repay all outstanding borrowings under its previous credit facilities. On a pro forma basis giving effect to the addition of the new facility and pay down of previous facilities, the Company had total liquidity of approximately $130 million, including cash of $69.5 million and availability under its revolving credit facilities of $60.5 million.

The Company’s existing $210 million unsecured senior notes, which bear interest at a rate of 8.2% and mature in 2022, are expected to be redeemed in full following a step down in redemption price at the end of January 2021. Upon redemption of the senior notes, annualized savings on cash interest expense are expected to approximate $11 million annually.

Business Outlook

Santiago Giraldo, Chief Financial Officer of Tecnoglass, stated, “Positive trends in our business have continued into the fourth quarter, with single-family residential representing a growing share of our revenues. Based on our current invoicing schedule and underlying market demand, we are providing a full year 2020 Adjusted EBITDA outlook of $95 million to $100 million. At the midpoint, this outlook implies Adjusted EBITDA growth of approximately 6% for the full year and 18% for the fourth quarter on a year-over-year basis. We expect revenue in the fourth quarter to be comparable to the prior year quarter, with a higher mix of product revenue versus installation revenue. Furthermore, we expect stronger demand in the U.S. to offset the slower recovery in Latin American markets.”

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.
