Description
Rambus Inc. (RMBS) Q2 2026 — Rambus (RMBS), the memory-interface chip and silicon-IP company that sits between the processor and the memory in every AI server, reported Q2 2026 (quarter ended June 30, 2026) after the close on July 27: record revenue of $207.4M (+20% YoY), above its own $192-198M guide; record product revenue of $99.2M (+22% YoY, +13% QoQ); royalties $84.3M (+23%); contract & other $24.0M (+8%). Non-GAAP diluted EPS $0.77 beat the ~$0.73 consensus; GAAP diluted EPS was $0.61. Operating cash flow $61.2M; cash and marketable securities $824.9M with zero debt (~$7.50/share of net cash). But underneath the records: GAAP operating margin FELL from 36.6% to 35.1% on +20% revenue, SG&A rose 36% versus revenue +20%, and Rambus booked a $3.3M restructuring charge plus facility-closure costs. The Q3 guide (revenue $210-216M) has product revenue rising to $110-116M while royalties — the ~100%-incremental-margin line — are guided DOWN to $69-75M, roughly -15% sequentially; licensing billings of $84.1M essentially matched reported royalty revenue and deferred revenue fell from $30.0M to $21.2M, so there is no deferred cash cushion. Stock-based comp was $15.9M, 7.7% of revenue, making non-GAAP EPS 26% higher than GAAP; Rambus repurchased zero shares in the quarter while the stock fell from $170 to $123, and insiders sold 25 times in six months with zero purchases. The company also disclosed in its Q1 2026 10-Q that it is responding to a federal grand jury subpoena in a criminal DOJ antitrust investigation. Our owner-earnings DCF — expensing stock comp honestly rather than using the non-GAAP figure, and adding back the $824.9M of net cash — lands fair value near $72 versus ~$83.21 today. Reverse-DCF: the current price requires ~20% owner-earnings growth per year for five straight years. Our call: AVOID, 3/5 — a great business, still about 13% above our fair value. Wall Street is Buy (11 buy / 3 hold / 0 sell, 14 analysts) with a $147.40 average target implying +77%, so we DIFFER sharply — and note most of those targets are dated April 28, 2026, before the 51% drawdown.
Rambus (RMBS) just delivered the best quarter in its history and the stock fell 14% in two sessions, capping a 51% collapse from its June 3 peak of $170.66 to roughly $83.21 today. Rambus makes the register clock drivers and companion chips that sit on DDR5 memory modules — the bottleneck every AI server is choking on — and licenses memory-interface and security IP. Q2 2026 (ended June 30): record revenue $207.4M (+20% YoY, above the $192-198M guide), record product revenue $99.2M (+22%), royalties $84.3M (+23%), contract & other $24.0M. Non-GAAP EPS $0.77 beat ~$0.73; GAAP EPS was $0.61. Cash and securities $824.9M with zero debt, and $61.2M of operating cash flow. So why the sell-off? Three things the headline buries. First, GAAP operating margin FELL from 36.6% to 35.1% on 20% revenue growth — negative operating leverage in a record quarter — as SG&A jumped 36% and the company took its first restructuring charge in years. Second, the Q3 guide has the near-100%-incremental-margin royalty line guided DOWN about 15% sequentially to $69-75M while lower-margin (~60% GM) product chips rise to $110-116M: Rambus is deliberately swapping hundred-cent dollars for sixty-cent dollars. Licensing billings of $84.1M essentially matched reported royalty revenue and deferred revenue fell from $30.0M to $21.2M, so there is no hidden deferred cushion — $84M was the peak, not the run rate. Third, stock-based comp of $15.9M is 7.7% of revenue, making non-GAAP EPS 26% flatter than GAAP, diluted shares still rose 1.4%, and Rambus repurchased ZERO stock while it fell from $170 to $123 — with insiders selling 25 times in six months and buying nothing. Add an open criminal DOJ antitrust grand jury subpoena disclosed in the Q1 10-Q. Our owner-earnings DCF (free cash flow less stock comp, plus the $824.9M net cash back) lands near $72 a share; run backwards, today's $83.21 requires ~20
