Over the past six months, Lennox’s shares (currently trading at $508.60) have posted a disappointing 15.3% loss, well below the S&P 500’s 10.2% gain. This was partly driven by its softer quarterly results and may have investors wondering how to approach the situation.

Why Does Lennox Spark Debate?

Based in Texas and founded over a century ago, Lennox (NYSE:LII) is a climate control solutions company offering heating, ventilation, air conditioning, and refrigeration (HVACR) goods.

Two Things to Like:

1. Operating Margin Rising, Profits Up

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.

Analyzing the trend in its profitability, Lennox’s operating margin rose by 5.2 percentage points over the last five years, as its sales growth gave it operating leverage. Its operating margin for the trailing 12 months was 20%.

2. Outstanding Long-Term EPS Growth

We track the long-term change in earnings per share (EPS) because it highlights whether a company’s growth is profitable.

Lennox’s EPS grew at an astounding 17.9% compounded annual growth rate over the last five years, higher than its 7.4% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

One Reason to be Careful:

Slow Organic Growth Suggests Waning Demand In Core Business

We can better understand HVAC and Water Systems companies by analyzing their organic revenue. This metric gives visibility into Lennox’s core business because it excludes one-time events such as mergers, acquisitions, and divestitures along with foreign currency fluctuations - non-fundamental factors that can manipulate the income statement.

Over the last two years, Lennox’s organic revenue averaged 3.9% year-on-year growth. This performance was underwhelming and suggests it may need to improve its products, pricing, or go-to-market strategy, which can add an extra layer of complexity to its operations. Lennox Organic Revenue Growth
