Conference Call Scheduled for Monday, May 19 at 9:00 am ET

First Quarter 2014 Overview

Barranquilla, Colombia – May 16, 2014 – Tecnoglass, Inc. (NASDAQ: TGLS; OTCBB: TGLSW) (“Tecnoglass” or the “Company”), a leading manufacturer of architectural glass, windows, and associated aluminum products for the global residential and commercial construction industries, today announced financial results for the first quarter (Q1) ended March 31, 2014.

José M. Daes, Chief Executive Officer of Tecnoglass, commented, “We began 2014 with strong sales growth, improved income, and higher Adjusted EBITDA. Our growth in Q1 2014 was driven by a significant increase in U.S. sales, which comprised over 45% of our total Q1 revenues. We have expanded outside of our traditional base in South Florida, and are now selling in cities including Washington, D.C., Baltimore, San Francisco, and New York.

“We have realized a number of benefits since becoming public in December 2013. Our bonding capacity has more than tripled to $200 million, allowing us to bid on larger projects around the world. This ability is evidenced in our backlog, which increased by more than $20 million during Q1 2014 to $140 million. Our balance sheet has been strengthened and our overall industry profile has been elevated. We expect to continue to benefit from the meaningful manufacturing and delivery cost advantages afforded by our location in Barranquilla, Colombia. In 2013, we completed a $29 million capital investment program that upgraded our facilities and our machinery, and significantly expanded our manufacturing capacity.”

Mr. Daes concluded, “Our business development efforts continue in earnest. We remain optimistic about our business and in our ability to meet anticipated growing global demand, all while providing the highest level of quality and customer service.”

First Quarter 2014 Results

Consolidated revenues for Q1 2014 rose 20.7% to $47.8 million from $39.6 million in Q1 2013. The majority of the increase was due to a $9.4 million rise in sales to the U.S. market as the Company continues to expand outside of its historical base in South Florida.

Gross profit rose to $14.6 million, or 30.5% of revenues, from $11.9 million, or 30.1% of revenues, in Q1 2013.

Selling and administrative expenses in Q1 2014 declined to $6.7 million, or 14.1% of revenues, from $7.0 million, or 17.6% in Q1 2013, reflecting a decline in sales commissions resulting from new sales arrangements in key markets, partially offset by modest increases in personnel costs driven by growth, significant public company expenses, and favorable exchange rates used in translating expenses to U.S. dollars.

Operating income rose 60% to $7.9 million from $4.9 million in the same period last year. As a percentage of consolidated revenues, operating income increased to 17% from 12% in Q1 2013, reflecting the operating leverage inherent in the Company’s business.

Net loss for Q1 2014 was $4.7 million, or $0.20 per diluted share, compared to net income of $2.5 million, or $0.12 per diluted share, in Q1 2013. Net income in Q1 2014 was impacted by an extraordinary non-cash, non-operating loss of $8.9 million as a result of the increase in the fair value of the warrant liability in Q1 2014 relative to its fair value at December 31, 2013. There was no comparable warrant liability in Q1 2013 since the Company only accrued the derivative obligation as a result of the merger which closed on December 20, 2013. The fair value of the warrants liability changes in response to market factors not directly controlled by the Company such as the market price of the Company’s shares and the volatility index of comparable companies.

Excluding the $8.9 million extraordinary loss for the warrants liability, net income for Q1 2014 was $4.2 million, or $0.17 per diluted share.

Adjusted EBITDA was $11.1 million, a 49% increase from $7.4 million in Q1 2013.

Backlog

Consolidated backlog stood at $140 million at March 31, 2014 compared to $120 million at December 31, 2013. Backlog consists primarily of contract sales for projects that can last up to several years until completion. Backlog should not be considered a comprehensive indicator of future revenues or prospects, as a significant portion of Tecnoglass’s revenues are derived from non-contract, standard sales.

2014 Forecast

Based on current business conditions, including forecasted growth in key markets, particularly the United States, Tecnoglass has increased its previously disclosed forecast for Adjusted EBITDA to approximately $46.0 million from approximately $42.2 million. Revenue, net income, and net income without the extraordinary effects of the warrant liability for 2014 are expected to approximate $205.7 million, $8.0 million, and $16.8 million, respectively.

Adjusted EBITDA Reconciliation

Adjusted EBITDA is not a measure of financial performance under generally accepted accounting principles (“GAAP”). Management believes Adjusted EBITDA, in addition to operating profit, net 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 might not be comparable to similarly-titled measures of other companies. This measure should be considered in addition to, and not as a substitute for or superior to, any measure of performance prepared in accordance with GAAP. A reconciliation of Adjusted EBITDA to the most directly comparable GAAP measure in accordance with SEC Regulation G follows:
