Approach 1: Applied Optoelectronics Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a company could be worth by projecting its future cash flows and discounting them back to today’s value using a required return.

For Applied Optoelectronics, the model used here is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow (FCF) is a loss of $310.8 million. Analysts provide FCF estimates out to 2027, with Simply Wall St extrapolating beyond that. The projection used for 2027 is $170.6 million of FCF, and by 2035 the extrapolated FCF used in the model is $635.2 million.

Discounting the projected cash flows in this way gives an estimated intrinsic value of $108.75 per share. Compared to the current share price of $86.33, this implies the stock trades at a 20.6% discount to the DCF estimate, which indicates an undervalued reading on this model.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Applied Optoelectronics is undervalued by 20.6%. Track this in your watchlist or portfolio, or discover 49 more high quality undervalued stocks.

Approach 2: Applied Optoelectronics Price vs Sales

For companies where earnings are not yet a steady guide, the P/S ratio is often a useful way to think about valuation because it compares what you are paying to the revenue the business is already generating.

Higher growth expectations and lower perceived risk tend to justify a higher “normal” or “fair” multiple, while slower growth and higher risk usually mean a lower multiple is more reasonable, even when looking at sales instead of earnings.

Applied Optoelectronics currently trades on a P/S ratio of 14.71x. That is well above the Communications industry average P/S of 1.95x and also above the peer group average of 3.83x. Simply Wall St’s Fair Ratio metric for the stock is 15.83x, which reflects factors such as the company’s earnings growth profile, profit margins, industry, market cap and specific risks.

The Fair Ratio aims to be more tailored than a simple comparison with peers or the broad industry, because it weighs the company’s own growth outlook, risk characteristics and profitability alongside its sector and size.

Comparing the current 14.71x P/S with the Fair Ratio of 15.83x suggests the share price is below that Fair Ratio benchmark.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Applied Optoelectronics Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives on Simply Wall St let you attach a clear story about Applied Optoelectronics to the numbers by linking your view of its future revenue, earnings and margins to a forecast, a Fair Value, and then a decision point on whether that Fair Value sits above or below the current price. All of this happens inside an easy Community tool that updates as new earnings or news arrive. One investor might back a more optimistic narrative that lines up with a Fair Value around US$50 and assumes faster growth from AI transceivers and new facilities. Another might choose a more cautious narrative that anchors to a Fair Value of US$15 and focuses on customer concentration risks and capital needs. Both can see in real time how updated assumptions change their Fair Value and therefore their view on whether the current price still fits their story.
