Kioxia Launches BiCS-10 Production, Targets AI Storage Market

• Kioxia and SanDisk have launched BiCS-10 production at their Beishang K2 facility, with 1 Tb TLC samples now shipping.
• The BiCS-10 interface speed has increased to 4.8 Gb/s, but BiCS-8 will remain the primary volume driver until March 2027.
• The target price of approximately 110,000 JPY implies about 32% upside, with risks centered on customer onboarding, K2 ramp-up, and supply disruptions.

Kioxia and SanDisk announced on July 3 that they have commenced production of the 10th-generation 3D Flash, known as BiCS-10, at the Kita-Kami Factory Fab2/K2 in Iwate Prefecture, Japan. On the same day, Kioxia began shipping 1 Tb TLC BiCS-10 samples, primarily targeting enterprise and data center SSDs.

This brings Kioxia’s AI data center storage roadmap to the pre-mass-production ramp-up stage, but it is not yet a signal of immediate profitability. Samples are being used for customer functionality validation, and mass-production specifications may still be adjusted. Further steps include enterprise SSD certification, product integration, and ramp-up at the K2 factory.

Morgan Stanley maintained its "overweight" rating on Kioxia in its latest report. Based on the report’s target price of approximately 110,000 JPY and Kioxia’s stock price of 83,300 JPY on July 3, this implies an approximate 32% upside potential. This outlook is not based on short-term volume growth from BiCS-10, but rather on Kioxia’s ability to translate faster interfaces, higher bit density, and lower power consumption into increased market share in AI data center SSDs and improved cash flow.

The financial forecast shows revenue of approximately JPY 8.54 trillion for FY2027e and approximately JPY 9.49 trillion for FY2028e, with profitability outlook tied to product portfolio upgrades.

The most direct change in BiCS-10 is increasing the NAND interface speed from 3.6 Gb/s in BiCS-8 to 4.8 Gb/s, an improvement of approximately 33%. For consumer storage, this metric may not be immediately apparent; however, for enterprise SSDs and AI servers, interface speed impacts data throughput, latency, and cache efficiency.

Kioxia's newly shipped 1 Tb TLC samples are targeted at enterprise and data center SSDs. In its 2026 Investor Day materials, the company positions the CM Series as a "High Bandwidth SSD with TLC Flash Memory," noting compatibility with NVIDIA CMX servers and optimization for KV cache workloads. This indicates that NAND in AI servers is no longer merely a cost-effective, high-capacity storage solution—it is also expected to handle data caching and access tasks closer to the computation layer.

BiCS-10 is a 332-layer 3D Flash. Compared to BiCS-8, the official specifications reveal a 59% increase in bit density, an 18% improvement in write power efficiency, and a 30% improvement in read power efficiency. Bit density affects capacity per wafer, while power consumption impacts data center operating costs. Cloud providers ultimately care about cost per TB, SSD performance, and total system energy consumption.

However, leading technical specifications do not equate to completed commercialization. Enterprise SSDs typically require lengthy certification cycles, especially for products featuring high performance, low latency, and AI workloads. BiCS-10 has already commenced production and entered sample shipment, but it still requires customer order confirmation to become a primary source of shipments and profits for Kioxia.

More easily overlooked is that Kioxia’s cost improvements over the next one to one and a half years will still primarily come from BiCS-8.

Morgan Stanley’s model expects company output expansion and GB cost reductions through the first half of 2027 to continue to be driven by BiCS-8. By the end of March 2027, BiCS Gen.8 is projected to account for over 80% of production in terms of GB. BiCS-10 is more of a starting point for medium- to long-term product structure upgrades rather than a single catalyst that will immediately impact short-term financial results.

This pace is not contradictory. The transition of NAND’s next-generation process from pilot production and sample shipments to large-scale adoption typically involves line switching, yield ramp-up, customer validation, and product mix adjustments. Since K2 Factory began production in September 2025, it has been manufacturing 8th-generation 3D Flash. As 10th-generation products are introduced, overall capacity will continue to expand, but profitability will only improve once utilization rates, yields, and customer orders catch up.

Kioxia's medium- to long-term goal is to increase the proportion of sales in the data center and enterprise markets to over 60%. The significance of BiCS-10 lies here: if the next-generation NAND successfully enters the high-end enterprise SSD market and gains greater market share in AI server storage, Kioxia's revenue structure will become more oriented toward the enterprise market.

Behind the approximately 32% upside potential is not just a bet on NAND price increases, but also the combination of technological upgrades, growing SSD market share in data centers, and improved free cash flow.

On valuation, the target price is based on an estimated free cash flow yield of approximately 10% for FY2028, implying a P/E ratio of about 11x. In the model, revenue is projected at approximately JPY 8.54 trillion for FY2027 and further increases to approximately JPY 9.49 trillion for FY2028; basic EPS is estimated at approximately JPY 8,782.8 and JPY 9,850.9, respectively. This assumes that Kioxia can translate technological advancements into improved product pricing and cost structures amid growing demand and supply constraints.

The market is willing to assign Kioxia a higher valuation, partly due to AI storage demand. Compared to consumer electronics and traditional PC cycles, data center SSDs are more driven by cloud capital expenditures, AI cluster construction, and enterprise storage upgrades. If BiCS-10 enters the high-end enterprise SSD market, Kioxia’s revenue quality and cyclical volatility could improve.

But this conversion chain is long. Technical specifications must first become products, products must pass customer certification, certification must be completed before shipment, and only then do they contribute to revenue and profit. Any delay in any step will affect the market’s assessment of profitability after 2027.

The stock price history chart shows Kioxia's stock price at approximately ¥83,300 as of July 3, 2026, with an "Overweight" rating marker overlaid.

The direction of BiCS-10 is relatively clear; the real uncertainty lies in execution.

First is customer certification. For high-end enterprise SSDs to enter the supply chains of cloud providers and data center customers, they must meet requirements for performance, stability, power consumption, and long-term availability. Sample shipments are just the beginning; the certification timeline and order volume determine when BiCS-10 will make a meaningful contribution to revenue.

Second is the ramp-up of the K2 factory. Switching to a new process typically affects yield and cost curves. Even after production has started, increasing capacity utilization takes time. If the ramp-up is slower than expected, the unit cost advantages and bit density benefits of BiCS-10 will be delayed.

Third is industry supply. Chinese manufacturers' expansion of NAND production could disrupt global supply and demand balance, particularly if demand recovers slower than expected, as additional supply would put downward pressure on prices and profit margins. Kioxia aims to increase its revenue share from AI SSDs, but still faces challenges from the storage price cycle and evolving competitive dynamics.

Exchange rates are also a direct risk. Morgan Stanley’s sensitivity analysis shows that for every 1-yen appreciation of the yen against the dollar, Kioxia’s annual operating profit decreases by approximately ¥6 billion. For storage manufacturers with global sales and yen-denominated financial statements, exchange rate fluctuations amplify uncertainty in profit forecasts.

BiCS-10 is more like a ticket for Kioxia to compete in the AI data center SSD market, rather than an already realized victory. Short-term financial results still depend on increased share of BiCS-8 and cost reductions, while medium- to long-term prospects hinge on BiCS-10 certification, K2 ramp-up, and enterprise SSD customer adoption. If these steps proceed smoothly, the approximately 32% upside potential will be more strongly supported; if any one of these elements is delayed, the technology leadership will still need confirmation through future earnings reports.
