Approach 1: Lumentum Holdings Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a stock could be worth by projecting future cash flows and discounting them back to today using a required return. It focuses on cash that can ultimately flow to shareholders rather than accounting profits.

For Lumentum Holdings, the model starts with last twelve month Free Cash Flow of about $135.9 million and projects it forward using analyst estimates and then extrapolations by Simply Wall St. By 2028, projected Free Cash Flow is $2,738.2 million, and the ten year path is laid out using a 2 Stage Free Cash Flow to Equity framework that blends analyst inputs with longer term estimates.

When these projected cash flows are discounted back to today, the DCF model produces an estimated intrinsic value of about $1,493.10 per share. Compared with the current share price of about $863.66, this implies the stock screens as around 42.2% undervalued under these assumptions.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Lumentum Holdings is undervalued by 42.2%. Track this in your watchlist or portfolio, or discover 49 more high quality undervalued stocks.

Approach 2: Lumentum Holdings Price vs Sales

For profitable companies where revenue is a key driver, the P/S ratio can be a useful way to compare what investors are paying for each dollar of sales. It is especially relevant when earnings are less stable or when profit margins differ across peers.

Growth expectations and risk tend to shape what looks like a “normal” P/S multiple. Higher expected growth or perceived resilience can justify a higher P/S, while greater uncertainty or thinner margins often point to a lower figure.

Lumentum Holdings currently trades on a P/S of about 27.00x. That sits well above the Communications industry average of 2.29x and also above the peer group average of 9.03x. Simply Wall St’s proprietary “Fair Ratio” for the stock is 29.09x, which is an estimate of what the P/S could be given factors such as earnings growth, industry, profit margins, market cap and company specific risks.

This Fair Ratio aims to be more tailored than a simple comparison with peers or the wider industry because it adjusts for those company specific characteristics rather than applying a single sector benchmark to everyone.

Comparing the current 27.00x P/S with the 29.09x Fair Ratio suggests Lumentum Holdings screens as undervalued on this metric.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Lumentum Holdings Narrative

Earlier the article mentioned that there is an even better way to think about valuation, and on Simply Wall St that takes the form of Narratives. These let you attach a clear story about Lumentum Holdings to the numbers, connect that story to a forecast for revenue, earnings and margins, and then see the implied fair value alongside the current share price so you can judge whether the stock looks expensive or cheap to you.

Each Narrative on the Community page is a simple, accessible tool that captures one user’s view of the company. These range from very bullish cases that assume revenue growth above 70% a year, profit margins above 35% and a fair value above US$1,000 per share, through to more cautious views that assume revenue growth closer to 18% a year, profit margins near 10% and a fair value near US$100. This allows you to see in one place how different assumptions lead to very different conclusions.

Because Narratives are linked to live data on Lumentum Holdings, they update automatically when new earnings, guidance or news come out. This helps you keep your own story and fair value current and compare it to the latest price before deciding whether the gap between value and price is wide enough for you to act.

For Lumentum Holdings however we will make it really easy for you with previews of two leading Lumentum Holdings Narratives:

On Simply Wall St you can quickly scan both a bullish and a bearish case, see the implied fair value for each, and then decide which set of assumptions feels closer to your own view of the stock at around US$863.66.

That way you are not just reacting to the latest price move. Instead, you are lining the current price up against clearly stated expectations for revenue growth, profit margins and valuation multiples.

Fair value in this bullish Narrative: about US$5,085.95 per share.

At the current price, this Narrative implies the stock is around 83% below its fair value, using ((5,085.95 minus 863.66) divided by 5,085.95).

Revenue growth assumption in this Narrative: 50.98%.

• Frames Lumentum as a high growth photonics manufacturer whose core cloud and AI data center optics business is the main long term value driver.
• Argues that recent improvements in margins, cash generation and balance sheet strength point to a genuine operational inflection, even if the recovery is still early.
• Accepts that the stock carries execution and cycle risk but views the underlying business quality and growth runway as strong enough to support a much higher fair value than today’s price.

Fair value in this bearish Narrative: about US$433.09 per share.

At the current price, this Narrative implies the stock is around 99% above its fair value, using ((863.66 minus 433.09) divided by 433.09).

Revenue growth assumption in this Narrative: 38.57%.

• Highlights heavy dependence on a small group of large cloud and telecom customers, with concern that pricing power and orders could weaken over time.
• Focuses on risks from rapid technology change, commoditisation and rising competition in photonics, which could make it harder to sustain margins as capacity expands globally.
• Aligns with analyst targets that sit well below the current price, arguing that even with revenue and margin improvement, expectations in the share price may already be high.

If you want to see how these Narratives stack up against the wider Community view, you can compare them with the full set of user and AI generated cases and see which assumptions you find most reasonable before making any decisions about Lumentum Holdings stock.
