The storage markets in which we offer our products continuously undergo technology transitions that we must anticipate and adapt our products to address in a timely manner. If we fail to implement new technologies successfully, or if we are slower than our competitors at implementing new technologies, we may not be able to competitively offer products that our customers desire or keep pace with ASP reduction, which could harm our operating results. For example, in transitioning our 2D NAND manufacturing capacity to 3D NAND technology, we could experience delays or other challenges in the production ramp, qualification of wafers, shipment of samples to customers or customer approval process. 3D NAND and any new manufacturing node may be more susceptible to manufacturing yield issues. Manufacturing yield issues may not be identified during the development or production process or solved until an actual product is manufactured and tested, further increasing our costs. If our technology transitions, including the production ramp of 3D NAND technology, take longer, are more costly to complete than anticipated, or do not improve manufacturing yield or other manufacturing efficiencies, our flash memory costs may not remain competitive with other flash-based memory producers or may not fall commensurate with declines in the price of flash-based memory, which would harm revenues, our gross margin and operating results.
For additional technology transition risks related to 3D NAND, see the risk factors entitled “ We rely substantially on our business ventures with Toshiba Memory Corporation (“TMC”) for the supply of flash-based memory and the development of flash-based technology, which subjects us to risks and uncertainties that could harm our business, financial condition and operating results ” and “Our strategic relationships subject us to risks that could adversely affect our business, financial condition and results of operations.”
With respect to HDDs, we announced that we will use microwave-assisted magnetic recording (MAMR) technology to increase HDD capacities. If our HDD technology transitions, including the production ramp of MAMR HDDs, take longer or are more costly to complete than anticipated or if we otherwise fail to implement new HDD technologies successfully, we may not remain competitive with other HDD producers, which could adversely affect our revenues, gross margin and operating results.
Moving to new technologies may require us to align to, and build, a new supply base. Our success in new product areas may be dependent in part on our ability to develop close relationships with new suppliers and on our ability to enter into favorable supply agreements. Where this cannot be done, our business and operations may be adversely affected. In addition, if our customers choose to delay transition to new technologies, if demand for the products that we develop is lower than expected or if the supporting technologies to implement these new technologies are not available, we may be unable to achieve the cost structure required to support our profit objectives or may be unable to grow or maintain our market position.
The substitution or replacement of our technologies and products by new technologies could make our products obsolete and harm our operating results.
Given the pace of technological development, there is a possibility that new technologies could substitute for or replace our current technologies and products and make them obsolete. Historically, when the industry experiences a fundamental change in storage technologies or standards, any manufacturer that fails to successfully and timely adjust its designs and processes to accommodate or manufacture the new technology or standard fails to remain competitive.
There are some revolutionary technologies that, if implemented by a competitor on a commercially viable basis ahead of the industry, could put us at a competitive disadvantage, including shingled magnetic recording, energy-assisted magnetic recording, patterned magnetic media and advanced signal processing.
Many companies, including some of our competitors, have also developed or are attempting to develop alternative non-volatile technologies, including non-NAND technologies such as magnetoresistive random-access memory (MRAM), resistive random-access memory (ReRAM) and phase change memory (PCM), and NAND-based vertical or stacked 3D memories based on charge trap, floating gate and other cell architectures. In addition, a provider of processors and non-volatile memory solutions may be developing a new standard to attach ultra-low latency non-volatile memory to its processor memory bus, which it may choose not to license to its competitors, resulting in it being a single source provider of such non-volatile memory solutions. As a result of these shifts in technology and standards, we could incur substantial costs in developing new technologies, such as recording heads, magnetic media and tools, in adopting new standards or in investing in different capital equipment or manufacturing processes to remain competitive. If we fail to successfully implement these new technologies or standards, or if we are significantly slower than our competitors at implementing new technologies or standards, we may not be able to offer products with capacities and capabilities that our customers desire, which could harm our operating results.
If we do not properly manage new product development, our competitiveness and operating results may be negatively affected.
Our success depends in part on our ability to develop and introduce new products in a timely manner in order to keep pace with technology advancements and compete with alternative storage technologies. If our products fail to offer a superior value proposition to alternative storage products, we will be at a competitive disadvantage and our business will suffer. As we introduce new products, standards or technologies, it can take time for these new standards or technologies to be adopted, for customers to accept and transition to these new standards or technologies and for significant sales to be generated, if at all. Failure of our customers to adopt our new products, standards or technologies could harm our results of operations as we fail to reap the benefits of our investments."
