How does Asetek's performance and growth trajectory compare to its key competitors in the liquid‑cooling market, and what market share implications might arise?

Fundamental snapshot – Asetek’s Q2‑2025 numbers show a 13 % YoY revenue decline to $11.2 m and a flat gross margin at 45 %. The adjusted EBITDA turned negative ($‑0.2 m versus $0.2 m a year ago), indicating that the company is now operating on thin profit cushions. The only bright spot is its liquid‑cooling segment, which rose to $9.8 m (up 14 % QoQ) after a strong Q1 rebound. This suggests that the core business – custom‑pump‑and‑cold‑plate solutions sold to OEMs and high‑end gamers – still has demand momentum, but the broader product mix (e.g., aftermarket kits, service contracts) is weakening.

Competitive context – Asetek’s main peers – Corsair (iCUE AIO), Cooler Master, EKWB, and Thermaltake – all posted double‑digit YoY growth in the first half of 2025, driven by a resurgence in PC gaming, the rollout of next‑gen GPUs and the early adoption of liquid‑cooling in data‑center servers. For example, Corsair’s AIO line grew ~22 % YoY, while EKWB expanded its enterprise‑grade liquid‑cooling modules ~18 % YoY, buoyed by new 800‑series GPU launches. Those competitors are also enjoying margins in the 48‑52 % range, outpacing Asetek’s 45 % and giving them more runway to reinvest in R&D and marketing.

Market‑share implications & trade idea – The lagging top‑line and deteriorating EBITDA signal that Asetek is ceding incremental market share to faster‑growing rivals, especially in the high‑margin OEM channel where Corsair and EKWB are now the preferred suppliers for new‑gen GPU integrations. Unless Asetek can accelerate its next‑generation pump designs (e.g., the announced “Gen 4” high‑flow pump) or secure new OEM contracts, its share of the $1.8 bn liquid‑cooling market could dip another 2–3 percentage points over the next 12 months. From a trading perspective, the stock is vulnerable to short‑term downside on earnings momentum concerns, but the quarterly QoQ rebound in liquid‑cooling revenue creates a potential catalyst if the company releases a new product line or announces a strategic partnership. A prudent approach is to reduce exposure (e.g., sell‑covered calls or a modest short position) while monitoring Asetek’s upcoming Q3 guidance and any partnership announcements that could arrest the share‑loss trend. If the company confirms a clear roadmap and improves margins toward the 48 %‑level, a re‑entry on pull‑back could be justified.
