Approach 1: Lumen Technologies Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model projects a company’s future cash flows and then discounts them back to today’s value, aiming to estimate what the entire business could be worth per share.

For Lumen Technologies, 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 about US$1.43b. Analyst inputs and further extrapolations produce a set of ten year projections, with forecast free cash flow for 2030 of US$27 million. Beyond the explicit analyst years, Simply Wall St extends the series using its own assumptions for the later period.

After discounting all those projected cash flows back to today, the model arrives at an estimated intrinsic value of about US$0.85 per share. Compared with the current share price of US$8.72, this indicates the stock is trading at a substantial premium to this DCF estimate, at roughly 9 times the modelled value.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Lumen Technologies may be overvalued by 929.5%. Discover 53 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Lumen Technologies Price vs Sales

For companies where earnings and book value are less reliable guides, the price-to-sales ratio (P/S) can be a useful way to think about what you are paying for each dollar of revenue. Investors usually accept a higher or lower P/S depending on what they expect for future growth and how risky the business appears, so there is no single “right” multiple that fits every stock.

Lumen Technologies currently trades on a P/S of 0.72x. This is below the broader Telecom industry average P/S of about 1.34x and well below the peer group average of 11.45x. On the surface that can suggest a discount, but simple peer or industry comparisons do not account for company specific factors such as growth profile, profitability, size and risk.

Simply Wall St’s Fair Ratio looks to adjust for these elements, and for Lumen it is 0.63x. Because this incorporates earnings growth assumptions, profit margins, industry, market capitalisation and risk, it can be a more tailored reference point than raw peer or industry averages. Comparing the Fair Ratio of 0.63x with the current 0.72x suggests Lumen trades modestly above this modelled level.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Lumen Technologies Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives bring this to life by letting you connect your view of Lumen Technologies to actual numbers such as future revenue, earnings, margins and a fair value, then compare that fair value to the current US$8.72 share price to see if your story implies room for upside or downside.

On Simply Wall St’s Community page, millions of investors can use Narratives as an accessible tool that links a company’s story to a forecast and a fair value that updates automatically when fresh news, earnings or analyst targets arrive.

For Lumen, one investor might build a bullish Narrative that leans toward the US$10.00 fair value implied by the highest analyst target, focusing on AI driven network contracts and multi cloud connectivity. Another investor might anchor on the US$6.00 or US$2.00 fair values from more cautious Narratives that stress competition, legacy revenue pressure and balance sheet risk. Your task is to decide which story and fair value range best fits your expectations.

For Lumen Technologies, here are previews of two leading Lumen Technologies narratives:

Fair value in this bullish narrative: US$10.00 per share

Implied undervaluation at the current US$8.72 share price: about 13% below this fair value

Revenue growth assumption in this narrative: 5.30% annual decline

• Focuses on network modernization, AI related demand for data infrastructure and a shift toward higher margin, recurring digital services.
• Assumes cost savings, lower capital spending and debt reduction help free up cash for reinvestment or capital returns, supporting improved profitability over time.
• Highlights risks from legacy revenue pressure, heavy competition and a sizable debt load that could weigh on the business if execution falls short.

Fair value in this more cautious narrative: US$7.68 per share

Implied overvaluation at the current US$8.72 share price: about 14% above this fair value

Revenue growth assumption in this narrative: 6.11% annual decline

• Credits Lumen with progress shifting toward enterprise and digital network services, including AI related connectivity and platform contracts, while still treating the profit outlook as uncertain.
• Assumes ongoing pressure from shrinking legacy products, a concentrated customer base and a sizeable debt burden that could make earnings and cash flows harder to sustain.
• Frames the current price as ahead of the analyst fair value, meaning the market is already factoring in a meaningful improvement in margins and execution.
