SIA Engineering Company Ltd Shares Are Near A 52-Week Low: Does The Company Have A Quality Business?

SIA Engineering Company Ltd (SGX: S59) provides aircraft maintenance, repair, and overhaul (MRO) services to over 80 international airlines around the world.

Right now, the company’s stock price is just 2% higher than a 52-week low of S$3.35, after falling by 8% over the last 12 months. This captured my attention and got me interested in finding out if SIA Engineering has a high quality business.

There’s no easy answer, but a simple metric can help shed some light on the question: The return on invested capital (ROIC).

A brief introduction to the ROIC

In a previous article of mine, I explained how the ROIC can be used to evaluate the quality of a business.

The simple idea behind the ROIC is that a business with a higher ROIC requires less capital to generate a profit, and it thus gives investors a higher return per dollar that is invested in the business. High-quality businesses tend to have high ROICs while the reverse is true – a low ROIC is often associated with a low-quality business.

You can see how the math works for the ROIC in the formula above.

SIA Engineering’s ROIC

Here’s a table showing how SIA Engineering’s ROIC looks like (I had used numbers from its fiscal year ended 31 March 2017):

In its fiscal year ended 31 March 2017 (FY16/17), SIA Engineering generated a ROIC of 16.7%. This is average, based on the ROICs of many other companies I have studied in the past. In other words, SIA Engineering has a business of average quality.

One point that investors should pay attention to here is that SIA Engineering derives a significant amount of profit from its various associates and joint ventures, which are excluded from the ROIC calculation. Thus, it may be useful to consider these investments separately to give a more holistic view of the quality of its business.
