Why Do We Think Somnigroup Will Underperform?
Despite the momentum, we're swiping left on Somnigroup for now. Here are three reasons we avoid SGI and a stock we'd rather own.
1. Long-Term Revenue Growth Disappoints
Examining a company’s long-term performance can provide clues about its quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Over the last five years, Somnigroup grew its sales at a 14.3% annual rate. Although this growth is acceptable on an absolute basis, it fell short of our standards for the consumer discretionary sector, which enjoys a number of secular tailwinds.

2. Cash Flow Margin Set to Decline
Free cash flow isn't a prominently featured metric in company financials and earnings releases, but we think it's telling because it accounts for all operating and capital expenses, making it tough to manipulate. Cash is king.
Over the next year, analysts predict Somnigroup’s cash conversion will slightly fall. Their consensus estimates imply its free cash flow margin of 10.3% for the last 12 months will decrease to 10.1%.
3. New Investments Fail to Bear Fruit as ROIC Declines
A company’s ROIC, or return on invested capital, shows how much operating profit it makes compared to the money it has raised (debt and equity).
We like to invest in businesses with high returns, but the trend in a company’s ROIC is what often surprises the market and moves the stock price. Over the last few years, Somnigroup’s ROIC has unfortunately decreased significantly. Paired with its already low returns, these declines suggest its profitable growth opportunities are few and far between.

Final Judgment
Somnigroup falls short of our quality standards. With its shares outperforming the market lately, the stock trades at 29.5× forward P/E (or $91.58 per share). At this valuation, there’s a lot of good news priced in - we think there are better stocks to buy right now. We’d recommend looking at a dominant Aerospace business that has perfected its M&A strategy.
