RMBS fell 28% from its June peak but holds a BUY rating, with a $108.43 base target and bull case reaching $173.

Astera Labs trades at a P/E of 283 versus Rambus's forward P/E of 24, while Marvell's hyperscaler demand signals a tailwind for RMBS royalties.

Our Rambus (NASDAQ:RMBS) call is constructive. After a violent June rally and sharp July pullback, the memory interface specialist trades in the shadow of its own overshoot. The 24/7 Wall St. price target for Rambus is $108.43 over the next 12 months, implying 5.38% upside from $102.89. Our recommendation is buy with high confidence at 0.9.

From June Peak to July Reset

Shares are down 6.16% over the past week and 28.19% over the last month after peaking near $143.29 on June 15. Even after that reset, RMBS is up 11.97% year to date and 59.45% over the past 12 months, trading 17% below the 52-week high of $174.10.

Fundamentals are strong. Q1 FY26 revenue hit $180.19 million, up 8.12% year over year, with product revenue climbing 15%. Non-GAAP EPS came in at $0.63, narrowly missing the $0.6363 consensus.

FY25 closed at $707.63 million in revenue, up 27.13%, and $360 million in operating cash flow. CEO Luc Seraphin flagged that "the growth of AI inference and agentic workloads in the data center continues to drive demand for higher memory bandwidth."

RMBS Earnings Explorer — 24/7 Wall St.The Bull Case

Our bull-case scenario points to $173.05 within 12 months, implying 68.19% upside. Analyst consensus sits at $144.57, with 7 buys, 2 holds, and zero sells. Drivers:

DDR5 Registered Clock Driver leadership, HBM4E memory controller IP marketed as the industry's fastest, and LPDDR5X SOCAMM2 chipset for next-generation AI servers. Q2 FY26 guidance calls for product revenue of $95 to $101 million, extending the Q4 FY25 record.

RMBS Price Scenario — 24/7 Wall St.What Could Go Wrong

The bear case targets $92.86, or -9.75% from here. Royalty revenue slipped to $69.64 million from $74 million a year ago. An analyst downgrade cited tightening DRAM supply. Non-GAAP operating margin compressed to 42% from 46% as R&D climbed 18%.

Insiders including the COO and multiple directors sold shares between $125.52 and $170.15 in May and June. Bulls counter that R&D spend of $50.23 million funds HBM4E and SOCAMM2 designs that should compound into product revenue for years.

RMBS Price Target — 24/7 Wall St.Rambus vs. Marvell and Astera Labs

Marvell Technology (NASDAQ:MRVL) is the scaled AI-silicon peer at a $180.6 billion market cap, with Q1 FY27 revenue of $2.42 billion and 27.6% growth. Marvell's data center segment dwarfs all of Rambus, giving investors a read on AI infrastructure demand: if hyperscaler capex holds for MRVL, Rambus royalty and product ramps should follow.

Astera Labs (NASDAQ:ALAB) is the growth counterpoint. ALAB grew Q1 FY26 revenue 93.4% to $308.4 million and trades at a P/E of 283. Rambus's 49 trailing and 24 forward P/E look reasonable against that. Peers make our $108.43 target look conservative on multiples but appropriate given Rambus's slower top-line trajectory.

Bottom Line

The 24/7 Wall St. price target for Rambus is $108.43, recommendation buy, confidence 90%. The combination of bullish analyst skew, tech sector tailwinds, and a derated price after the June pullback tips the scale.

Confidence rises if Q2 FY26 product revenue lands at the high end of the $95 to $101 million guide and royalty revenue stabilizes. The setup weakens if DRAM supply tightens further or margin compression persists.

RMBS Analyst Ratings — 24/7 Wall St.Rambus Price Prediction 2026-2030

Our model projects the following trajectory under base-case assumptions, extending the 247Factor framework across a 5.18% annualized base-case return.

Year

24/7 Wall St. Price Target

2026

$108.43

2027

$106.32

2028

$111.61

2029

$118.51

2030

$127.10

These projections assume Rambus converts its DDR5, HBM4E, and SOCAMM2 pipeline into royalty and product revenue at its historical clip. A step-change in AI memory adoption could push results toward the bull path near $339 by 2031; a DRAM supply squeeze or major license loss could pin them near the bear path.
