Company Overview
The first-ever Colombian company to trade on the NASDAQ, Tecnoglass (NYSE: TGLS) is a manufacturer of architectural glass, windows, and aluminum products.
Revenue Growth
A company’s long-term performance is an indicator of its overall quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Thankfully, Tecnoglass’s 20.3% annualized revenue growth over the last five years was incredible. Its growth beat the average industrials company and shows its offerings resonate with customers.
Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. Tecnoglass’s annualized revenue growth of 10.8% over the last two years is below its five-year trend, but we still think the results suggest healthy demand. 
This quarter, Tecnoglass reported year-on-year revenue growth of 12%, and its $249 million of revenue exceeded Wall Street’s estimates by 2.7%.
Looking ahead, sell-side analysts expect revenue to grow 11.1% over the next 12 months, similar to its two-year rate. This projection is admirable and implies the market is baking in success for its products and services.

Operating Margin
Tecnoglass has been a well-oiled machine over the last five years. It demonstrated elite profitability for an industrials business, boasting an average operating margin of 26.8%. This result isn’t surprising as its high gross margin gives it a favorable starting point.
Analyzing the trend in its profitability, Tecnoglass’s operating margin decreased by 2.9 percentage points over the last five years. This raises questions about the company’s expense base because its revenue growth should have given it leverage on its fixed costs, resulting in better economies of scale and profitability.
This quarter, Tecnoglass generated an operating margin profit margin of 18%, down 6.7 percentage points year on year. Since Tecnoglass’s operating margin decreased more than its gross margin, we can assume it was less efficient because expenses such as marketing, R&D, and administrative overhead increased.
Earnings Per Share
We track the long-term change in earnings per share (EPS) for the same reason as long-term revenue growth. Compared to revenue, however, EPS highlights whether a company’s growth is profitable.
Tecnoglass’s EPS grew at 26.8% compounded annual growth rate over the last five years, higher than its 20.3% annualized revenue growth. However, this alone doesn’t tell us much about its business quality because its operating margin didn’t improve.
We can take a deeper look into Tecnoglass’s earnings quality to better understand the drivers of its performance. A five-year view shows that Tecnoglass has repurchased its stock, shrinking its share count by 6.4%. This tells us its EPS outperformed its revenue not because of increased operational efficiency but financial engineering, as buybacks boost per share earnings. 
Like with revenue, we analyze EPS over a shorter period to see if we are missing a change in the business.
For Tecnoglass, its two-year annual EPS declines of 1.7% mark a reversal from its (seemingly) healthy five-year trend. We hope Tecnoglass can return to earnings growth in the future.
In Q1, Tecnoglass reported adjusted EPS of $0.78, down from $0.92 in the same quarter last year. Despite falling year on year, this print beat analysts’ estimates by 8.3%. Over the next 12 months, Wall Street expects Tecnoglass’s full-year EPS of $3.44 to shrink by 19.8%.
Key Takeaways from Tecnoglass’s Q1 Results
It was great to see Tecnoglass’s full-year EBITDA guidance top analysts’ expectations. We were also glad its revenue outperformed Wall Street’s estimates. On the other hand, its adjusted operating income missed and its full-year revenue guidance was in line with Wall Street’s estimates. Overall, this print was mixed but still had some key positives. The stock traded up 4.7% to $46.12 immediately following the results.
Is Tecnoglass an attractive investment opportunity at the current price? What happened in the latest quarter matters, but not as much as longer-term business quality and valuation, when deciding whether to invest in this stock.
