A：The growth and impact of AI is accelerating across numerous industries. Generative AI models are becoming the norm, and AI scaling is driving business productivity, making AI a strategic enabler of business transformation. AI inference is taking hold in various applications such as chatbots, virtual assistants, and customer relationship management tools. Physical AI innovations are also advancing rapidly, fueling the demand for larger multimodal models and generating a high demand for data storage.

A：Western Digital is managing the surge in demand by focusing on increasing drive aerodynamic density and accelerating the adoption of higher capacity drives and ultra SMR technology. They have shipped over 3.5 million units of their latest generation products and have started qualification of their Hammer and Next generation EPM with hyperscale customers. The company is also acquiring intellectual property and talent for developing internal laser capability and has announced Ultra SMR enable platforms to expand the technology's adoption.

A：Western Digital has secured firmed purchase orders with their top customers through the calendar year 2027 and 2028. They have also entered into robust commercial agreements with a significant portion of their top 20 customers for the same duration. These agreements signify a strong trust and confidence in Western Digital's ability to meet their future storage needs.

A：The purpose of Western Digital's Innovation day is to share updated roadmaps for their Hammer and E PMR products and provide further details on core innovations that are being developed to enhance drive performance, energy efficiency, and throughput. The company will also update their financial model and continue to support the next generation of their products.

A：Western Digital delivered a strong financial performance in the latest quarter with revenue of $3 billion, up 22% year over year, and earnings per share of $2.00, which was above the high end of the guidance range. They achieved a gross margin of 40.1%, an operating income of slightly above $2 billion, and an operating margin of 33.8%. Additionally, they had a net debt position of $3.8 billion and a net leverage EBITDA ratio well below 100%, with strong free cash flow generation of $253 million for the quarter.

A：Western Digital plans to achieve continued favorable trends in its business by maintaining a disciplined approach to free cash flow, capital returns, and long-term value creation for shareholders, as evidenced by the guidance for the next quarter.

A：The anticipated incremental margin is between Ed and script, depending on the perspective, which suggests a potential script incremental margin flow-through. The cost curve per terabyte is expected to be durable, with stable pricing and cost benefits from moving customers to higher capacity drives, alongside cost reduction in manufacturing assets and throughout the supply chain.

A：Western Digital considers a stable pricing environment with prices slightly up on a per terabyte basis, as well as cost reductions from upshifting customers to higher capacity drives and effective execution in driving down costs in manufacturing and throughout the supply chain.

A：Western Digital is planning to monetize the remaining Ed Ed million Sandisk shares before the script year anniversary of the separation, likely through a debt-for-equity swap, and use the proceeds to further reduce debt.

A：Western Digital has shifted its focus to a more customer-centric approach, dedicated teams for big hyperscale customers, better technology roadmap development, and improved visibility of demand requirements. This has led to the structuring of longer-term, LTAs with customers and an improved relationship that should support future innovations, especially those related to AI needs.

A：The strategic plan for the remaining Sandisk shares involves focusing on share repurchase or discussing future plans, although specific details on the focus area were not provided in the transcript.

A：The company has repurchased 1.3 billion of the authorized script billion dollar share repurchase program since its announcement, using about 1.3 billion dollars and has acquired approximately 60 million shares. There is a commitment to continue utilizing the program.

A：The company is shifting to higher capacity drives, with an increasing adoption of ultra SMR drives, which are gaining popularity among customers. Major customers are fully onboard with ultra SMR drives, and more are transitioning. This shift will likely increase the proportion of ultra SMR in the company's total nearline exabyte base, which is crucial for serving customer demand and will positively impact profitability due to higher script capacity uplift over CMR and industry standard SMR, as well as being a software-based solution that is very accretive from a gross margin standpoint.

A：The JBOD launch is significant as it expands the ultra SMR customer reach beyond what has been targeted so far, further promoting the adoption of ultra SMR technology.

A：The yields on the company's EPM products are very good, in the lower Eds percentage range. Reliability and quality feedback from customers have been positive, with over 3.5 million units of the flagship EPM R drives being delivered. As the ultra SMR mix increases, costs decline, which also impacts the cost down. These factors, along with the performance of the Rochester lab in ensuring product quality, contribute to a positive cost per bit for clients.

A：The Rochester lab has played a critical role in the qualification process of the new products. The company has started the qualification of Hammer drives and next-generation EPM drives in the first half of the calendar year. Rochester ensures product reliability and quality during the transition from qualification to production. Further details on these developments will be shared at the Innovation Day on February.

A：The company has been working on Hammer for some time, and the engineering teams are making good progress. Investments in Hammer will continue, but once the ramp-up begins, it is expected to be neutral to accretive to gross margins. CapEx as a percentage of revenue is expected to remain within script to script range even as Hammer ramps up.

A：The demand for AI inference is anticipated to drive a significant need for data storage, as more data is created and stored to deliver inference. This creates a positive impact on hard drive sales, especially given that hyperscalers are adept at managing data economics and can drive mass adoption of AI, further increasing the demand for data storage on hard drives.

A：The company has initiated qualification of Hammer technology with one hyperscale customer this month and plans to start with another soon. This indicates the company's strategy to engage with multiple hyperscale customers for additional ex-mike capacity, beyond the initial customer engagement.

A：The innovative technology acquired will reduce energy requirements to support the lasers compared to conventional laser diodes.

A：There is a roadmap for developing solutions that integrate hard drives with AI or machine learning to bring more intelligence to storage and manage the higher storage requirements.

A：The company has already initiated the qualification process for the Hammer drive with one customer and plans to start with a second customer. They are focusing on meeting strong demand for exabytes from customers using hard drives and are also qualifying their next-generation EPM R drives, which are scalable and deliver large volumes of drives.

A：Gross margins are expected to be neutral to accretive for Hammer once it reaches the same scale as the EPMR portfolio.

A：The quarterly and year-over-year change in revenue per exabyte is driven by strong demand from the cloud segment, particularly hyperscale customers. This has led to increased bids and revenues, with stable pricing that was up single-digit year on year.

A：Customer qualifications and efficiencies have positively impacted the company's performance, with an increase in the delivery of exabytes, particularly driven by the cloud portfolio.

A：Future cost reductions are expected through innovation and upshifting customers to higher capacity drives, including Ultra SMR. These actions are expected to lead to further cost reductions on a cost per terabyte basis, potentially reaching about a 10% reduction, and could be accelerated with potential map changes.

A：The company is looking forward to sharing its findings on how much further it can increase storage density with the current CMR and LSM technologies before considering the implementation of Hammer drives.
