Company Overview

Operating at the intersection of policy, technology, and implementation for over five decades, ICF International (NASDAQ: ICFI) provides professional consulting services and technology solutions to government agencies and commercial clients across energy, health, environment, and security sectors.

Revenue Growth

A company’s long-term sales performance is one signal of its overall quality. Any business can put up a good quarter or two, but many enduring ones grow for years.

With $1.82 billion in revenue over the past 12 months, ICF International is a mid-sized business services company, which sometimes brings disadvantages compared to larger competitors benefiting from better economies of scale.

As you can see below, ICF International’s 3.6% annualized revenue growth over the last five years was tepid. This shows it failed to generate demand in any major way and is a rough starting point for our analysis.

Long-term growth is the most important, but within business services, a half-decade historical view may miss new innovations or demand cycles. ICF International’s performance shows it grew in the past but relinquished its gains over the last two years, as its revenue fell by 3.9% annually.

ICF International also reports its backlog, or the value of its outstanding orders that have not yet been executed or delivered. ICF International’s backlog reached $3.4 billion in the latest quarter and averaged 6.1% year-on-year declines over the last two years. Because this number is lower than its revenue growth, we can see the company hasn’t secured enough new orders to maintain its growth rate in the future.

This quarter, ICF International missed Wall Street’s estimates and reported a rather uninspiring 10.3% year-on-year revenue decline, generating $437.5 million of revenue.

Looking ahead, sell-side analysts expect revenue to grow 7% over the next 12 months, an improvement versus the last two years. This projection is healthy and suggests its newer products and services will fuel better top-line performance.

Adjusted Operating Margin

Adjusted 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 because it excludes non-recurring expenses, interest on debt, and taxes.

ICF International’s adjusted operating margin has more or less stayed the same over the last 12 months , averaging 8.1% over the last five years. This profitability was mediocre for a business services business and caused by its suboptimal cost structure.

Analyzing the trend in its profitability, ICF International’s adjusted operating margin might fluctuated slightly but has generally stayed the same 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, ICF International generated an adjusted operating margin profit margin of 8%, in line with the same quarter last year. This indicates the company’s overall cost structure has been relatively stable.

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.

ICF International’s EPS grew at 7.1% compounded annual growth rate over the last five years. This performance was better than its revenue growth but doesn’t tell us much about its business quality because its adjusted operating margin improvement was less than peers.

Like with revenue, we analyze EPS over a shorter period to see if we are missing a change in the business.

For ICF International, its two-year annual EPS declines of 4% show it’s continued to underperform. These results were bad no matter how you slice the data.

In Q1, ICF International reported adjusted EPS of $1.50, down from $1.94 in the same quarter last year. This print missed analysts’ estimates. Over the next 12 months, Wall Street expects ICF International’s full-year EPS of $6.30 to grow 14.7%.

Key Takeaways from ICF International’s Q1 Results

It was good to see ICF International narrowly top analysts’ full-year EPS guidance expectations this quarter. We were also glad its full-year revenue guidance slightly exceeded Wall Street’s estimates. On the other hand, its revenue missed and its EPS fell short of Wall Street’s estimates. Overall, this was a softer quarter. The stock remained flat at $74.50 immediately following the results.

Is ICF International an attractive investment opportunity right now? 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.
