Why Does Omnicom Group Spark Debate?

With a vast network of creative agencies that helped craft some of the most memorable ad campaigns in history, Omnicom Group (NYSE: OMC) is a strategic holding company that provides advertising, marketing, and communications services to many of the world's largest companies.

Two Positive Attributes:

1. Long-Term Revenue Growth Shows Momentum

Examining a company’s long-term performance can provide clues about its quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years. Luckily, Omnicom Group’s sales grew at a decent 5.6% compounded annual growth rate over the last five years. Its growth was slightly above the average business services company and shows its offerings resonate with customers.

2. Increasing Free Cash Flow Margin Juices Financials

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.

As you can see below, Omnicom Group’s margin expanded by 7.2 percentage points over the last five years. This is encouraging, and we can see it became a less capital-intensive business because its free cash flow profitability rose while its operating profitability was flat. Omnicom Group’s free cash flow margin for the trailing 12 months was 16.1%.

One Reason to be Careful:

Slow Organic Growth Suggests Waning Demand In Core Business

Investors interested in Advertising & Marketing Services companies should track organic revenue in addition to reported revenue. This metric gives visibility into Omnicom Group’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, Omnicom Group’s organic revenue averaged 4.3% year-on-year growth. This performance slightly lagged the sector 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.

Final Judgment

Omnicom Group’s positive characteristics outweigh the negatives, but at $77.80 per share (or 7.1× forward P/E), is now the right time to buy the stock? See for yourself in our in-depth research report, it’s free.
