Company overview

Allegion plc (NYSE: ALLE) is a provider of security products and solutions that keep people and assets safe and secure in various environments.

Revenue growth

Reviewing a company’s long-term sales performance reveals insights into its quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Thankfully, Allegion’s 8.8% annualized revenue growth over the last five years was decent. Its growth was slightly above 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. Allegion’s annualized revenue growth of 8.6% over the last two years aligns with its five-year trend, suggesting its demand was stable.

We can dig further into the company’s sales dynamics by analyzing its organic revenue, which strips out one-time events like acquisitions and currency fluctuations that don’t accurately reflect its fundamentals. Over the last two years, Allegion’s organic revenue averaged 4.6% year-on-year growth. Because this number is lower than its two-year revenue growth, we can see that some mixture of acquisitions and foreign exchange rates boosted its headline results.

This quarter, Allegion reported year-on-year revenue growth of 9.6%, and its $1.17 billion of revenue exceeded Wall Street’s estimates by 3.3%.

Looking ahead, sell-side analysts expect revenue to grow 3.5% over the next 12 months, a deceleration versus the last two years. This projection is underwhelming and suggests its products and services will face some demand challenges. At least the company is tracking well in other measures of financial health.

Operating margin

Operating margin is an important measure of profitability as it shows the portion of revenue left after accounting for all core expenses — everything from the cost of goods sold to advertising and wages. It’s also useful for comparing profitability across companies with different levels of debt and tax rates because it excludes interest and taxes.

Allegion 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 20.1%. This result isn’t surprising as its high gross margin gives it a favorable starting point.

Looking at the trend in its profitability, Allegion’s operating margin rose by 4.1 percentage points over the last five years, as its sales growth gave it operating leverage.

This quarter, Allegion generated an operating margin profit margin of 24.3%, up 2.4 percentage points year on year. The increase was encouraging, and because its operating margin rose more than its gross margin, we can infer it was more efficient with expenses such as marketing, R&D, and administrative overhead.

Earnings per share

Revenue trends explain a company’s historical growth, but the long-term change in earnings per share (EPS) points to the profitability of that growth — for example, a company could inflate its sales through excessive spending on advertising and promotions.

Allegion’s decent 9.4% annual EPS growth over the last five years aligns with its revenue performance. This tells us its incremental sales were profitable.

Like with revenue, we analyze EPS over a more recent period because it can provide insight into an emerging theme or development for the business.

For Allegion, its two-year annual EPS growth of 9% is similar to its five-year trend, implying stable earnings power.

In Q3, Allegion reported adjusted EPS of $2.60, up from $2.30 in the same quarter last year. This print beat analysts’ estimates by 3.9%. Over the next 12 months, Wall Street expects Allegion’s full-year EPS to grow 9.3% from $8.74 to $9.55.

Key takeaways from Allegion’s Q3 results

We were impressed by how significantly Allegion blew past analysts’ organic revenue expectations this quarter. We were also glad its revenue outperformed Wall Street’s estimates. Zooming out, we think this was a solid print. The stock remained flat at $159.02 immediately after reporting.

Allegion may have had a good quarter, but does that mean you should invest right now?
