Overview

We provide traditional enterprise, high-volume hyperscale datacenter, and workstation solutions that accelerate databases, virtualization, cloud computing, big data, information systems, and the applications that help drive business from the smallest e-tailers to some of the world's largest data centers, social media leaders, and Fortune Global 500 businesses. Our integrated hardware and software platform enables the acceleration of data away from legacy architectures and specialized hardware. This core technology leverages flash memory to significantly increase datacenter and computer-based information system efficiency, with enterprise grade performance, reliability, availability, and manageability.

We were incorporated in December 2005, and we initially focused on the engineering and development of our platform. We have experienced significant growth with revenue increasing from $158.5 million in the six months ended December 31, 2011 to $238.7 million in the six months ended December 31, 2012. Our headcount increased from 554 employees as of December 31, 2011 to 803 employees as of December 31, 2012.

We sell our products through our global direct sales force, OEMs, including Cisco, Dell, HP, and IBM, and other channel partners. Some of our OEMs and channel partners integrate our platform into their own proprietary product offerings. Our primary sales office is located in San Jose, California, and we also have additional sales presence in North America, Europe, and Asia.

Large purchases by a limited number of customers have accounted for a substantial majority of our revenue, and the composition of the group of our largest customers changes from period to period. Some of our customers make concentrated purchases to complete or upgrade specific large-scale data storage installations. These concentrated purchases are short-term in nature and are typically made on a purchase order basis rather than pursuant to long-term contracts. Sales to our 10 largest customers, including the applicable OEMs, accounted for 95% and 89% of revenue during the three months ended December 31, 2011 and 2012, respectively, and 93% and 89% of revenue during the six months ended December 31, 2011 and 2012, respectively. Our direct customer Facebook, Apple, through a reseller, and our OEM customer HP each accounted for 43%, 14%, and 14% of our revenue, respectively, during the three months ended December 31, 2011, 34%, 16%, and 19% of our revenue, respectively, during the three months ended December 31, 2012, 27%, 29%, and 18% of our revenue, respectively, during the six months ended December 31, 2011, and 31%, 22%, and 17% of our revenue, respectively, during the six months ended December 31, 2012. We expect that revenue from sales to certain key customers will decline significantly for the three months ending March 31, 2013, and the six months ending June 30, 2013, as they complete their planned deployments. As a result of our revenue concentrations, our quarterly revenue and operating results are likely to fluctuate in the future and will be difficult to estimate. We expect that sales to a limited number of customers will continue to contribute materially to our revenue for the foreseeable future.

We anticipate that sales through OEMs and other channel partners will continue to constitute a substantial portion of our future revenue. In some cases, our products must be designed or qualified into the OEM's products. If that fails to occur for a given product line of an OEM, we would likely be unable to sell our products to that OEM during the life cycle of that product, which would adversely affect our revenue. We expect that as we continue to expand our global presence and business overseas, we will increasingly depend on our OEM relationships in such markets.

We believe that extending our platform differentiation through software innovation will be critical to achieving broader market acceptance and to maintaining or increasing our gross margins. In this regard, our ioTurbine virtualization software, directCache data-tiering software, ION Data Accelerator software, ioSphere platform management software, and storage memory programming software allowing Integrated Software Vendors to develop, integrate, and add significant value to applications using our platforms and we intend to continue adding software functionality to differentiate our products. The next generation VSL 3.0 virtualization software and hardware platform is in full production. We continue to devote the majority of our research and development resources to software development, and if we are unable to successfully develop or acquire, and then market and sell additional software functionality, our ability to increase our revenue and gross margins could be adversely affected.

Our ioMemory technology forms the basis of our hardware offering and is designed as a portfolio of upgradeable design modules, enabling faster time-to-market and increased extensibility, and it provides server-based storage class memory, low access latency, field upgradeability, deep error correction, self-healing protection and native PCI Express connectivity. Our second generation ioMemory technology supports the latest NAND geometries, significantly increases performance and capacity, improves reliability while retaining the ability to build storage systems of varying capacity, performance, and form factors. At the heart of the ioMemory technology is our proprietary field programmable data-path controller. It connects a large array of non-volatile memory chips natively to the server's PCI-Express 1.0 or 2.0 peripheral bus, and addresses the reliability issues of non-volatile memory with our Adaptive Flashback Protection advanced chip-level fault tolerance technology, which is capable of restoring, correcting, and resurrecting lost data in the Flash-based storage sub-system.

Our portfolio of storage class memory products incorporates our ioMemory based hardware subsystems and related VSL and caching software into our family of ioDrive, ioDrive2, ioScale, ioCache, and ioFX enterprise grade products. Our ioDrive, ioDrive2, ioScale, ioCache, and ioFX products work in conjunction or are integrated with our ioTurbine virtualization caching software, directCache data-tiering software, and ION Data Accelerator software. Our recently introduced ioScale product is derived from our ioMemory platform and is specifically designed for the unique needs of the high-volume hyperscale market.

We outsource manufacturing of our hardware products using a limited number of contract manufacturers. We procure a majority of the components used in our products directly from third-party vendors and have them delivered to our contract manufacturers for manufacturing and assembly. Once our contract manufacturers perform sub-assembly and assembly quality tests, they are assembled to our specified configurations. We perform final manufacturing assurance tests, labeling, final configuration, including a final firmware installation and shipment to our customers.

As a consequence of the rapidly evolving nature of our business and our limited operating history, we believe that period-to-period comparisons of revenue and other operating results, including gross margin and operating expenses as a percentage of our revenue, are not necessarily meaningful and should not be relied upon as indications of future performance. Although we have experienced significant percentage growth in our revenue, we do not believe that our historical growth rates are likely to be sustainable or indicative of future growth.

Components of Consolidated Statements of Operations

Revenue

We derive revenue primarily from the sale of our storage class memory products and support services. We sell our storage class memory platforms and software through our global direct sales force, OEMs, and other channel partners. We provide our support services pursuant to support contracts, which involve hardware support, software support, and software upgrades on a when-and-if available basis for a period of one to five years. We recorded revenue from support services of $3.0 million and $9.0 million for the three months ended December 31, 2011 and 2012, respectively, and $5.1 million and $16.5 million for the six months ended December 31, 2011 and 2012, respectively. For the periods presented, our software revenue was not significant to our condensed consolidated statements of operations.

Cost of Revenue

Cost of revenue consists primarily of material costs including amounts paid to our suppliers and contract manufacturers for hardware components and assembly of those components into our products. The largest portion of our cost of revenue consists of the cost of non-volatile memory components. Given the commodity nature of memory components, neither we nor our contract manufacturers generally enter into long-term supply contracts for our product components, which can cause our cost of revenue to fluctuate. Cost of revenue is recorded when the related product revenue is recognized. Cost of revenue also includes costs related to allocated personnel expenses related to customer support, warranty costs, costs of shipping, manufacturing operations, and carrying value adjustments recorded for excess and obsolete inventory.

Operating Expenses

The largest component of our operating expenses is personnel costs, consisting of salaries, benefits, and incentive compensation for our employees, which includes stock-based compensation.

Sales and Marketing

Sales and marketing expenses consist primarily of personnel costs, incentive compensation, marketing programs, travel-related costs, consulting expenses associated with sales and marketing activities, and facilities-related costs.

Research and Development

Research and development expenses consist primarily of personnel costs, prototype expenses, amortization of an intangible asset, consulting services, depreciation associated with research and development equipment, and facilities-related costs. We expense research and development costs as incurred.

General and Administrative

General and administrative expenses consist primarily of personnel costs, legal expenses, consulting and professional services, audit costs, and facility-related expenses for our executive, finance, human resources, information technology, and legal organizations.

Other income (expense), net

Other income (expense), net consists of changes in the fair value of a derivative related to a repurchase of our common stock, interest expense, interest income, and transactional foreign currency gains and losses.

Trends in Our Business

Gross Margin

Our gross margin will vary due to product mix, customer demand, and opportunities to drive market adoption.

Sales and Marketing

We plan to continue to invest in sales by increasing our sales headcount. Our sales personnel are typically not immediately productive and therefore the increase in sales and marketing expense when we add new sales representatives is not immediately offset by increased revenue and may not result in increased revenue over the long-term. The timing of our hiring of new sales personnel and the rate at which they generate incremental revenue could therefore affect our future period-to-period financial performance. We expect sales and marketing expenses to increase in absolute dollars and increase as a percentage of revenue as we expect to continue hiring new sales representatives. We also expect to expand marketing activities to drive sales opportunities and brand awareness.

Research and Development

We expect to continue to devote substantial resources to the development of our products including the development of new products. We believe that these investments are necessary to maintain and improve our competitive position. We expect research and development expenses to increase in absolute dollars and increase as a percentage of revenue as we expect to continue to invest in additional engineering personnel and infrastructure required to support the development of new products and to enhance existing products.

General and Administrative

While we expect personnel costs, including stock-based compensation expense, to be the primary component of general and administrative expenses, we also expect to continue to incur significant legal and accounting costs related to compliance with rules and regulations applicable to public companies. We expect that general and administrative expenses will continue to increase in absolute dollars and as a percentage of revenue primarily due to general growth of the business, infrastructure costs to support our international growth, and in legal costs related to intellectual property.
