The most valuable input Corsair Gaming sells is not made by Corsair. Its Vengeance and Dominator memory kits are DRAM chips bought from the three companies that fabricate them, screened, clipped into a heatsink and resold to people building their own PCs. That makes Corsair — a Fremont, California maker of gaming keyboards, mice and headsets, Elgato streaming gear and DIY PC components — one of the few consumer names with direct revenue leverage to the memory cycle. In the June quarter, the leverage worked in reverse.

Revenue in Gaming Components and Systems, the larger of Corsair's two segments, fell 9% year on year to $198.5m. Memory revenue within it rose 17%. The gap is the whole story: units are going down while prices go up, because the enthusiast staring at a $550-to-$700 sticker for a 32GB DDR5 kit — roughly $9 to $14 per gigabyte, up 40% to 60% from the 2024 floor — waits. Corsair's management calls that deferral rather than destruction, arguing that buyers waiting for cheaper memory will give up waiting because memory is not getting cheaper. It probably is not: server DRAM contract prices were set to rise 13% to 18% in the third quarter and to keep climbing through 2027 as fabs redirect capacity to AI systems.

The cost side is guided down too. Corsair told investors memory gross margin in that segment goes from about 23% in the September quarter to the high teens in December. Its edge in components is procurement and shelf space, not technology: Kingston, G.Skill, TEAMGROUP and Crucial buy the same die for the same socket.

What is actually branded

The other half is better. Gamer and Creator Peripherals grew 13% to $115.9m at a 44.9% gross margin, up from 40%, led by Fanatec sim-racing hardware. Elgato Marketplace revenue and transactions each more than doubled, and a minority stake in show-control software maker Bitfocus makes the Stream Deck the default control surface in professional live-events rigs. That is where switching costs live.

Group revenue still fell 1.8% to $314.3m, a second straight decline. Reported gross margin hit a record 33.2%, but roughly 500 basis points of that was a one-off $15.6m tariff refund; underlying is nearer 28%. Cash flow was real — operating cash flow up 148%, and $75.1m of net cash.

The shares rose 35.25% on 7 August, the day after the beat and raise. Every bit of the month's advance is that one session; strip it and the same 30 days are down about 11%. They have fallen 20.6% from the 7 August close, and on 19 August Goldman Sachs initiated coverage at Sell with an $11 target, citing AI build-outs competing for the same memory supply and a forecast 15% drop in industry PC shipments this year. Price-to-trailing-gross-profit has expanded about 69% since mid-May, to 2.65x from roughly 1.57x, on 36.2x trailing earnings — while consensus has fiscal 2026 revenue falling 2.0%.

Logitech pre-bought the problem

Logitech, the $14.4bn Swiss maker of mice, keyboards and Microsoft Teams and Zoom room systems, has the same input and none of the exposure. It secured memory through fiscal 2027 and raised video-collaboration prices 13% in May to cover the cost. June-quarter revenue grew 6.9% to $1.227bn, gross margin reached 49.5% (44.8% excluding tariff refunds) and operating income rose 59.5%. Pointing devices grew 14%; video collaboration grew 9%, against an installed base of meeting rooms now six years old and a refresh cycle of five to seven. Fewer than half of PCs have a mouse — the growth mechanism is attachment and premiumisation, not PC unit shipments, which is why Corsair's headwind is not Logitech's.

The stock went nowhere anyway, down 1.2% over 30 days and 17.5% below its 1 June close. The cause is specific and disclosed: a semiconductor supplier's plant shut in late June, costing about $20m of September-quarter sales and up to $200m in December, with no reopening date. Price-to-gross-profit has de-rated roughly 21% from the June high to 6.52x, and forward earnings of 17.9x sit below trailing 18.3x — consensus now models fiscal 2027 revenue up 1.2%. Rivals Yealink and HP's Poly are pressing on room-system share while the outage runs.

One of these companies is priced for a memory cycle that is shrinking its unit base. The other has contracted its way around the cycle and is discounted for a factory it does not own.

The setup

Where it stands — Corsair has given back most of a one-day earnings pop; Logitech is growing and de-rated on a supplier outage. Would confirm — Corsair's components segment returns to growth in the September quarter as deferred builds convert. Would invalidate — Corsair's memory gross margin lands below the guided high teens, or Logitech's outage extends past fiscal Q4. Watch next — Logitech's fiscal Q2 report in late October, guided to 0-3% constant-currency growth and roughly 44% gross margin. Valuation — Corsair: 36.2x trailing, 15.8x forward earnings; 2.65x gross profit against 1.57x in mid-May. Logitech: 18.3x trailing, 17.9x forward.
