Applied Optoelectronics (AAOI) Stock Looks Reasonable As Its 10x Run Turns Heads

Applied Optoelectronics has delivered a very large 3 year share price gain, which puts fresh attention on whether its current market value lines up with its sales base. After a sharp run followed by recent pullbacks, the question for investors is how that price stacks up against what the company is actually generating in revenue.

  • Over the past 3 years the stock has returned about 10x, which puts a lot of weight on whether the present valuation can be backed by the scale and growth of its sales.
  • The completion of a roughly US$600m at the market equity offering strengthens Applied Optoelectronics' balance sheet and may support higher future sales capacity, but it also increases the equity value that needs to be supported by those revenues.
  • Your read on Applied Optoelectronics is one view; the desks covering it have another. See what analysts think Applied Optoelectronics's shares could be worth.

The stock's next move may depend on whether Applied Optoelectronics' current share price is justified by its sales relative to what investors are paying per dollar of revenue.

Is Applied Optoelectronics Still Cheap on Sales?

P/S works well for Applied Optoelectronics because investors are mainly weighing what they pay for its revenue base while profits are still volatile. On this yardstick, the stock trades around 12.7x sales, which is far above the Communications industry average of about 2.2x and also well ahead of the peer group near 6.2x. That kind of revenue multiple means buyers today are putting a high price on each dollar of current turnover.

Because the completed US$600m at the market offering has sharpened focus on growth plans, the question is whether that premium can be explained by expectations for scaling in AI focused optical hardware. The fair value framework, which looks at Applied Optoelectronics' growth profile, profitability potential, market size and risks, suggests the present P/S sits below the multiple that model would ascribe. So even with the share price reacting positively to the capital raise earlier this year, the stock still screens as undervalued on this revenue based lens for investors who are comfortable with the underlying assumptions.
