Rambus (RMBS) Launches New AI Memory Chip As Valuation Debate Heats Up

Simply Wall St · 1d ago

Rambus (RMBS) just put a fresh product in front of investors, unveiling a new power management IC designed for LPDDR6 SOCAMM2 server memory, aimed at AI infrastructure and power efficiency.

Rambus has been active on the product front, yet the share price has softened recently, with a 30-day share price return down 4.29% and a 90-day move down 10.07%. This contrasts with the 3-year total shareholder return of 77.47% and 5-year total shareholder return of 304.71%, which point to a much stronger longer run record that investors will weigh against this new LPDDR6 SOCAMM2 PMIC launch.

Rambus now trades below the average analyst target after a recent pullback. At the same time, the business has just introduced new AI oriented products. Is that caution sensible, or is the gap too wide?

Most Popular Narrative: 34% Undervalued

Rambus last closed at $92.80 while the most followed narrative points to a fair value of about $141.57. The story centers on whether the current discount lines up with the company’s AI focused product and cash generation profile.

The current valuation implies that Rambus shares do not fully reflect the combination of record revenue, strong cash from operations and ongoing buybacks, which supports the view that the stock is undervalued and that the overall narrative remains bullish.

See why 36 investors see Rambus as 34% undervalued.

Result: Fair Value of $141.57 (UNDERVALUED)

Still, the Rambus story can change quickly if margin pressure persists or if the antitrust investigation escalates and starts to drag on cash generation.

Another Take On Rambus: Cash Flow Model Flashes Caution

The first narrative leans on analyst fair value of $141.57, yet the Simply Wall St DCF model points the other way. On that cash flow view, Rambus shares at $92.80 trade well above an estimated future cash flow value of about $32.66, which frames the stock as expensive rather than discounted. Which set of assumptions do you trust more, the earnings path or the cash generation projected into that model?

For anyone weighing that gap, it helps to see exactly how those long term cash estimates are built in the SWS DCF model, step by step, before leaning on either signal too heavily. Look into how the SWS DCF model arrives at its fair value.
