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

A Discounted Cash Flow model estimates what Applied Optoelectronics might be worth today by projecting the company’s future cash flows and discounting them back to a present value using a required rate of return.

For Applied Optoelectronics, the latest twelve month Free Cash Flow (FCF) is a loss of $374.6 million. The DCF used here is a 2 Stage Free Cash Flow to Equity model that starts with this current FCF profile and then applies analyst estimates and extrapolated projections. For example, FCF for 2027 is projected at $168.3 million, and by 2035 the model extrapolates FCF of $710.1 million, with interim years gradually stepping up to that level.

Pulling these projections together, the DCF model arrives at an estimated intrinsic value of $106.84 per share for Applied Optoelectronics. Compared with the recent share price of $138.54, the model implies the stock is about 29.7% overvalued based on these assumptions and cash flow forecasts.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Applied Optoelectronics may be overvalued by 29.7%. Discover 43 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Applied Optoelectronics Price vs Sales

For companies like Applied Optoelectronics where earnings and cash flows can be volatile, the Price to Sales (P/S) ratio is often a useful way to think about valuation, because it compares the stock price with the revenue the business is generating rather than profits that may be temporarily low or negative.

What counts as a “normal” or “fair” P/S ratio depends on how much growth investors expect and how risky they see the stock. Higher expected growth and lower perceived risk generally support a higher multiple, while lower growth expectations and higher risk usually point to a lower one.

Applied Optoelectronics currently trades on a P/S of 21.93x. That sits well above the Communications industry average P/S of 2.09x and also above the peer group average of 7.04x. Simply Wall St’s Fair Ratio framework estimates what the P/S might be based on factors such as growth characteristics, profit margins, industry, market cap and key risks, and arrives at a Fair Ratio of 48.49x. Because this Fair Ratio is materially higher than the current 21.93x, the P/S approach suggests the stock may be undervalued on these inputs.

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 step in as a simple tool on Simply Wall St’s Community page that lets you attach your own story about Applied Optoelectronics to the numbers by linking a view on its future revenue, earnings, margins and fair value to today’s share price, then showing whether your fair value suggests the stock is cheap or expensive, updating automatically as new news or earnings arrive. One investor might build a bullish Narrative around a fair value of US$220.00 based on faster growth and higher earnings, while another might lean on a more cautious Narrative with a fair value of US$57.50 that focuses on customer concentration and execution risk. Both can see at a glance how those different stories translate into very different opinions on what the shares are worth.

For Applied Optoelectronics, we will make it really easy for you with previews of two leading Applied Optoelectronics Narratives:

🐂 Applied Optoelectronics Bull Case

Fair value: US$151.30

Implied mispricing vs last close: the shares are about 8.4% below this fair value based on the narrative assumptions.

Revenue growth assumption: 113.04%

• Analysts build a case around rapid uptake of 400G, 800G and future 1.6T optical transceivers, paired with large hyperscale and CATV pipelines and expanding U.S. and Taiwan manufacturing capacity.
• The narrative leans on internal efficiency gains, vertical integration and wafer scale upgrades that are expected to support higher margins and long term earnings power.
• At the same time it highlights heavy customer concentration, sizable capital spending, execution challenges and industry level pressures that could limit how much of the growth story is ultimately reflected in profits.

🐻 Applied Optoelectronics Bear Case

Fair value: US$78.00

Implied mispricing vs last close: the shares are about 77.6% above this fair value based on the narrative assumptions.

Revenue growth assumption: 57.68%

• This narrative frames Applied Optoelectronics as a high-risk AI infrastructure stock where the market already prices in a large portion of the potential upside from 800G and 1.6T transceiver demand.
• It emphasizes that customer concentration, rapid planned revenue ramp, dilution from equity issuance and geopolitical exposure could all matter if expectations on orders, margins or capacity ramp timing are not met.
• The author views the stock as suitable only for investors comfortable with very high volatility and execution risk, with valuation leaving limited room for setbacks.
