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

A Discounted Cash Flow, or DCF, model takes forecast cash flows that a company may generate in the future and discounts them back to today using a required rate of return. The idea is to estimate what those future cash flows are worth in present terms.

For Lumentum Holdings, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month free cash flow is a loss of about $64.1 million. Looking ahead, analysts and extrapolated estimates point to free cash flow of $241.6 million in 2026, rising to $647.7 million in 2028. Further projections out to 2035 are also in the hundreds of millions of dollars.

When these projected cash flows are discounted back to today, the intrinsic value comes out at about $233.67 per share. Compared with the recent share price of $324.25, the DCF suggests the stock is around 38.8% overvalued on this model.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Lumentum Holdings may be overvalued by 38.8%. Discover 863 undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Lumentum Holdings Price vs Sales

For companies where earnings can be less stable, the P/S ratio is a useful way to think about valuation because it compares what you are paying to the revenue the business generates, rather than to profits that can swing around more.

In general, higher expected growth and lower perceived risk can justify a higher “normal” or “fair” P/S multiple. Lower growth expectations or higher risk tend to support a lower multiple. That context helps when you look at where Lumentum trades today.

Lumentum currently trades on a P/S of 12.48x. This sits above the Communications industry average P/S of 2.04x and the peer group average of 7.55x. Simply Wall St’s Fair Ratio for Lumentum is 5.42x, which is its proprietary estimate of what a reasonable P/S might be given factors such as the company’s earnings growth profile, industry, profit margins, market cap and risk characteristics.

The Fair Ratio can often be more useful than a straight comparison with peers or the broad industry because it tries to adjust for those company specific features, rather than assuming one size fits all. Compared with the current 12.48x P/S, the 5.42x Fair Ratio points to Lumentum trading on a richer multiple than this framework would imply.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Lumentum Holdings Narrative

Earlier we mentioned that there is an even better way to understand valuation. On Simply Wall St’s Community page you can use Narratives, which are short, evidence based stories that tie your view of Lumentum Holdings’ business to specific forecasts for revenue, earnings and margins. These Narratives then convert those forecasts into a Fair Value you can compare with the current price. They update automatically when fresh news or earnings arrive. Narratives can also differ widely between investors. For example, one Narrative may use the analysts’ higher fair value of about US$255 per share, based on expectations for AI driven optical demand and higher future P/E multiples. Another Narrative might lean on the lowest analyst price target of US$83 with more cautious assumptions around customer concentration, competition and margins.
