After a strong five year run, with Simon Property Group stock returning 135.8%, the current market price of US$226.22 still sits below an intrinsic value estimate that points to the shares trading at a discount of about 25.2%. The broader valuation checks also lean in the same direction.

• Over the last 5 years, Simon Property Group has returned 135.8%. This puts fresh attention on whether the current price still leaves a margin between market value and intrinsic value.
• Expectations for continued real estate cash flow may support the current valuation, while any setback in those cash flows or higher capital requirements could weigh on what investors are willing to pay for the stock.
• On Simply Wall St's broader checks, Simon Property Group screens as undervalued in 5 of 6 valuation areas. This suggests the shares lean cheap across several lenses rather than just on one model.

The issue now is whether that apparent discount to intrinsic value provides enough cushion for investors after such a strong multi year share price performance.

Does Simon Property Group Look Undervalued on Cash Flow?

The Discounted Cash Flow (DCF) model here uses adjusted funds from operations to estimate what Simon Property Group might be worth based on its future cash generation.

On this approach, Simon Property Group is valued using last twelve month free cash flow of about $4.0b and a set of projections that assume growing cash flows rather than sharp swings. When those projected cash flows are discounted back, the model points to an intrinsic value of about $303 per share, compared with the current price of $226.22, which implies the stock trades at a 25.2% discount.

Because Simon Property Group recently raised its full year 2026 Real Estate FFO guidance, the current pricing gap suggests the market is not fully aligning that outlook with the cash flow value implied by this DCF model.

Overall, the DCF workup indicates Simon Property Group stock appears undervalued relative to its estimated intrinsic value.

Our Discounted Cash Flow (DCF) analysis suggests Simon Property Group is undervalued by 25.2%. Track this in your watchlist or portfolio, or discover 47 more high quality undervalued stocks.

Is Simon Property Group Still Cheap on Earnings?

The P/E ratio is a useful cross check for Simon Property Group because earnings are a key yardstick for listed real estate businesses. At a current P/E of 15.6x, Simon Property Group trades at a sizeable discount to the Retail REITs industry average of about 27.6x and well below the peer group average of 33.6x.

On Simply Wall St's fair P/E estimate of 24.8x, which reflects factors such as the company’s size, sector and risk profile, the current 15.6x multiple sits well under what might be expected. That gap suggests the market is pricing Simon Property Group below both its own fair P/E benchmark and broader sector levels, even after the strong share price performance highlighted earlier in the analysis.

Taken together, the P/E comparison indicates Simon Property Group stock appears undervalued on an earnings multiple basis.

The Bottom Line

For Simon Property Group, both the Discounted Cash Flow (DCF) intrinsic value estimate and the earnings multiple view point in the same direction, with the stock screening as undervalued rather than stretched. The broader valuation checks also lean supportive, so the core question is whether the current cash flow outlook and earnings profile are strong enough to close that gap over time. What matters most from here is whether the real estate cash flows and guidance that underpin those models prove durable enough to justify a higher valuation, or whether the current discount is the market correctly pricing in execution and capital allocation risks.
