BARRANQUILLA, Colombia – May 4, 2023 – Tecnoglass, Inc. (NYSE: 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 first quarter ended March 31, 2023.

José Manuel Daes, Chief Executive Officer of Tecnoglass, commented, “Our strong momentum continued into 2023 with record first quarter results. We generated year-over-year growth in all of our key operating metrics, resulting in record first quarter revenues, gross profit, Adjusted EBITDA¹, operating cash flow and free cash flow. This performance further builds upon our established track record of achieving strong financial performance and returns for shareholders, derived from a multi-year effort to fortify our architectural glass platform through sound investments in strategic automation and capacity enhancements. Our continued expanding backlog resulted in a third straight quarter of approximately 60% year-over-year growth in multifamily/commercial revenues. We were also particularly pleased with the continued rapid growth of our single-family residential products. The shorter cash cycle in our single-family residential business, along with our prudent working capital management, also helped us generate our 13^th consecutive quarter of strong cash flow. Achieving these results amid a challenging macro-economic backdrop further validates our growth strategy and our structural competitive advantages. Overall, I am proud of the efforts of all of our team members and as we look to the balance of the year, we believe we have all of the tools in place to execute against our multi-faceted growth strategy to further cement our position as an industry leader in the architectural glass market.”

Christian Daes, Chief Operating Officer of Tecnoglass, added, “We are thrilled to report an excellent start to the year as demand for our single-family residential and multifamily/commercial products remains strong. We are encouraged by the solid levels of quoting and bidding activity in our markets, with the accelerating growth in our backlog to a record $776 million at quarter-end, reflecting an increasing number of projects in our commercial pipeline with visibility well into 2024. We are encouraged to see the Architectural Billings Index (ABI), which forecasts business conditions for the mid-to-high-rise end-market, return to expansionary levels in March, which further validates what we are seeing in our main markets. On all sides of our business, our ability to timely deliver best-in-class products is driving significant revenue growth and market share gains. We remain focused on consistently improving within our vertically-integrated operations as we continue to produce innovative new products and geographic diversification.”

First Quarter 2023 Results

Total revenues for the first quarter of 2023 increased 50.6% to $202.6 million compared to $134.5 million in the prior year quarter, driven by a significant increase in the Company’s multifamily/commercial activity, strong growth in single-family residential activity and market share gains. Single-family residential revenues increased 40% year-over-year, representing 41% of total revenues for the first quarter, helped by market share gains and the continued positive demographic trends in the Company’s main markets. Multifamily/commercial revenues increased 59% year-over-year, attributable to the previously mentioned increase in commercial construction projects which were previously put on hold during the pandemic or moved into designing and permitting stages in the last 18 months given the positive demographic shifts in our main markets. Changes in foreign currency exchange rates had an adverse impact of $1.2 million on both Colombia revenues and total revenues in the quarter.

Gross profit for the first quarter of 2023 increased 78.6% to $107.8 million, representing a 53.2% gross margin, compared to gross profit of $60.3 million, representing a 44.8% gross margin in the prior year quarter. The 830 basis point improvement in gross margin mainly reflected operating leverage on higher sales, favorable pricing dynamics and greater operating efficiencies related to prior automation initiatives.

Selling, general and administrative expense (“SG&A”) was $34.1 million for the first quarter of 2023 compared to $26.4 million in the prior year quarter, with the increase attributable to higher shipping and commission expenses as a result of a higher sales volume, as well as a higher provision for bad debt expenses and incremental marketing costs associated with the expansion of our new showrooms. As a percent of total revenues, SG&A was 16.8% for the first quarter of 2023 compared to 19.6% in the prior year quarter driven by better operating leverage.

Net income was $48.4 million, or $1.01 per diluted share, in the first quarter of 2023 compared to net income of $21.0 million, or $0.44 per diluted share, in the prior year quarter, including a non-cash foreign exchange transaction loss of $1.1 million in the first quarter of 2023 and a $2.9 million loss in the first quarter of 2022. As previously disclosed, these non-cash 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 $51.5 million, or $1.08 per diluted share, in the first quarter of 2023 compared to adjusted net income of $25.4 million, or $0.53 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 89.3% to $85.8 million, or 42.4% of total revenues, in the first quarter of 2023, compared to $45.4 million, or 33.7% of total revenues, in the prior year quarter. The improvement was driven by higher sales and stronger gross and operating margins. Adjusted EBITDA¹ included a $1.5 million contribution from the Company’s joint venture with Saint-Gobain, compared to $0.8 million in the prior year quarter.

Balance Sheet & Liquidity

The Company ended the first quarter of 2023 with total liquidity of approximately $300 million, including cash and cash equivalents of $128.5 million and availability under its committed revolving credit facilities of $170 million. Given the Company’s continued growth in Adjusted EBITDA¹ and strong cash generation, debt leverage continues to trend lower and now stands at 0.1 times net debt to LTM Adjusted EBITDA¹, compared to 0.6 times in the prior year quarter.

Dividend

The Company declared a quarterly cash dividend of $0.09 per share for the first quarter of 2023, representing a 20% increase from the previous dividend, which was paid on April 28, 2023 to shareholders of record as of the close of business on March 31, 2023.

Full Year 2023 Outlook

Santiago Giraldo, Chief Financial Officer of Tecnoglass, stated, “We are increasing our full year 2023 outlook to reflect our strong start to 2023 and positive sales momentum into the second quarter, reflected by record invoicing months in March and April. We now expect full year 2023 revenues to grow organically to a range of $810 million to $850 million (approximately 16% growth at the midpoint of the range) and for Adjusted EBITDA¹ to increase to a range of $315 million to $335 million. This implies Adjusted EBITDA¹ growth of approximately 23% at the midpoint driven by stronger than originally anticipated gross margins. The structural advantages provided by our vertically integrated business model, as well as the investments we have made in our production capabilities, put Tecnoglass firmly on track to meet the strong demand anticipated in our updated outlook for the full year 2023.”

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.
