• Wondering if Lumentum Holdings at US$890.09 is still offering value or if most of the opportunity is already priced in? This article walks through the numbers so you can judge that for yourself.
• The stock has been volatile recently, declining 10.3% over the past week and slipping 0.4% over the past month. It still sits on very large 1 year and multi year returns that suggest investors have been willing to pay up in the past.
• Recent headlines around Lumentum have focused on its position in the communications and photonics space and how the stock fits into broader tech market themes. That backdrop, combined with the sharp pullback in the last week, has shifted attention back to whether the current price fairly reflects the company’s prospects and risks.
• Lumentum currently holds a valuation score of 4/6, which means it screens as undervalued on four of six checks. Next up is a closer look at how different valuation approaches assess the stock and how you can go one step further than those models by the end of this article.

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

The Discounted Cash Flow model estimates what a stock could be worth by projecting future cash flows and discounting them back to today’s value. It focuses on the cash the business is expected to generate for shareholders rather than just reported earnings.

For Lumentum Holdings, the model used is a 2 Stage Free Cash Flow to Equity approach, built on $135.9 million of last twelve months free cash flow. Analyst and extrapolated projections in the model point to free cash flow rising into the hundreds of millions of dollars over the next decade, with Simply Wall St extending estimates beyond the initial analyst horizon.

Under these assumptions, the DCF model arrives at an estimated intrinsic value of about $1,649.67 per share. That figure is above the recent share price of $890.09, which implies a discount of roughly 46.0%. On this basis, the stock appears materially undervalued relative to the cash flows currently incorporated in the model.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Lumentum Holdings is undervalued by 46.0%. Track this in your watchlist or portfolio, or discover 54 more high quality undervalued stocks.

Approach 2: Lumentum Holdings Price vs Earnings

For profitable companies, the P/E ratio is a useful way to think about what you are paying for each dollar of current earnings. It ties the share price directly to the bottom line and gives you a quick sense of how the market is weighing those earnings against other opportunities.

What counts as a “normal” P/E depends on how fast earnings are expected to grow and how risky those earnings appear. Higher expected growth or lower perceived risk can justify a higher multiple, while slower growth or higher risk usually point to a lower one.

Lumentum currently trades on a P/E of 145.37x. That is well above the Communications industry average of 30.55x and the peer group average of 36.91x. Simply Wall St’s Fair Ratio model, which blends factors such as earnings growth, profit margins, industry, market cap and company specific risks, suggests a Fair P/E of 204.15x. Because this Fair Ratio is higher than the current P/E, the multiple based view indicates the stock is undervalued relative to what the model implies investors might typically pay for its profile.

Result: UNDERVALUED

Together they show how different assumptions about cloud and AI demand, margins and customer risk can lead to very different views on what the stock is worth. Your job is not to pick a winner on the spot, but to see which set of assumptions feels closer to how you see the business.

Fair value: US$904.89 per share

Discount or premium to that fair value at US$890.09: about 1.6% below the narrative fair value

Revenue growth assumption: 64.07% a year

• Assumes strong growth in AI, cloud and data center optics, supported by higher capacity, new products and long term customer commitments.
• Builds in rising profit margins over time as higher value photonics, optical circuit switches and co packaged optics scale.
• Relies on Lumentum maintaining technology leadership while managing customer concentration, competition and geopolitical risks.

Fair value: US$433.09 per share

Overvaluation on this view at US$890.09: about 105.6% above the narrative fair value, a little over 2x that fair value.

Revenue growth assumption: 38.57% a year

• Focuses on customer concentration risk and the chance that pricing power shifts toward a small group of large cloud buyers.
• Highlights the risk that fast moving photonics technology and new low cost suppliers could compress margins over time.
• Builds in the possibility that expectations around AI optics demand, capacity ramps and new products prove too optimistic.
