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

A DCF model projects a company’s future cash flows and discounts them back to today’s value, aiming to estimate what the business might be worth based on those cash flows rather than its current share price.

For Applied Optoelectronics, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is a loss of $310.84 million. Analysts provide estimates out to 2027, with free cash flow in 2027 projected at $170.60 million. Beyond that, Simply Wall St extrapolates ten year projections, with free cash flow in 2035 estimated at $635.17 million, all in $.

By discounting these projected cash flows back to today, the model arrives at an estimated intrinsic value of $107.57 per share. Compared with the recent share price of $183.51, this indicates that, on this DCF view, the stock is trading at a 70.6% premium to the model’s estimate of intrinsic value.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Applied Optoelectronics may be overvalued by 70.6%. Discover 51 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Applied Optoelectronics Price vs Sales

P/S is a common way to compare higher growth or less predictable companies because it focuses on revenue rather than profits, which can swing around more from year to year. Investors usually accept a higher multiple when they expect stronger growth or see lower risk, while slower growth or higher risk tends to justify a lower, more conservative multiple.

Applied Optoelectronics currently trades on a P/S of 31.28x. That is well above the Communications industry average P/S of 2.43x and also above the peer group average of 4.58x. To give more context, Simply Wall St calculates a proprietary “Fair Ratio” of 36.07x for the company. This is the P/S multiple that might be expected given factors such as its growth profile, industry, profit margins, market value and specific risks, rather than just a simple comparison to peers.

Because the Fair Ratio is tailored to Applied Optoelectronics’ own characteristics, it can provide a more nuanced view than broad industry or peer averages. On this basis, the current P/S of 31.28x sits below the Fair Ratio of 36.07x, which points to the shares trading below this model-based reference point.

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, so here is Narratives, a simple way for you to attach a clear story about Applied Optoelectronics to the numbers such as your fair value, and your expectations for future revenue, earnings and margins.

A Narrative connects what you believe about the business to a full financial forecast, then to a fair value that you can compare with the current share price to decide whether it looks high, low or roughly in line with your view.

On Simply Wall St, Narratives sit inside the Community page and are used by millions of investors as an accessible tool. They let you pick or adjust assumptions instead of building a spreadsheet, and then automatically translate that into a Fair Value that updates as new earnings or news come in.

For Applied Optoelectronics, one investor might align with a more optimistic Narrative that points to a Fair Value of US$190 per share based on faster growth and higher margins. Another might lean toward a more cautious Narrative closer to US$54 per share. By comparing those story driven fair values to the current price of US$183.51, you can decide which Narrative best matches your own expectations.

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

Each one ties a clear story about the business to specific forecasts and a Fair Value, so you can quickly see which version fits closest with your own expectations.

Fair Value: US$190.00

Implied undervaluation vs current price: 3.4%

Revenue growth assumption: 103.66%

• Sets out a high growth case where revenue expands very quickly on the back of 400G, 800G and 1.6T optical transceiver demand, with analysts expecting revenue growth of 103.66% a year over the next three years.
• Builds in a sharp uplift in profitability, with margins moving from a loss position today to a profit margin of 23.37% in three years, and earnings modeled at US$899.8m by around May 2029.
• Anchors the Fair Value at US$190 based on those earnings and a P/E of 24.61x in 2029. It also flags meaningful risks around customer concentration, rapid technology shifts and geopolitical exposure.

Fair Value: US$78.00

Implied overvaluation vs current price: 135.3%

Revenue growth assumption: 57.68%

• Frames Applied Optoelectronics as an AI infrastructure supplier with strong exposure to 800G and 1.6T datacenter optics, but with the current market value already embedding a large share of expected progress.
• Assumes solid revenue growth of 57.68% and a profit margin of 7.0%, while highlighting that the share price asks a lot on execution, including capacity ramp up, customer retention, margins and capital discipline.
• Emphasizes key risks such as heavy customer concentration, potential dilution from equity issuance, geopolitical and supply chain exposure, and the possibility that any disappointment could lead to a sharp valuation reset.
