Overview

We are a product driven company that leverages innovative proprietary technologies to deliver networking solutions with compelling price-performance characteristics to both start-up and established network operators and service providers. Our products bridge the digital divide by fundamentally changing the economics of deploying high performance networking solutions in underserved and underpenetrated wireless broadband access markets globally. These markets include emerging markets and other areas where individual users and small and medium sized enterprises do not have access to the benefits of carrier class broadband networking. Our business model has enabled us to break down traditional barriers, such as high product and network deployment costs, which are driven by business model inefficiencies and achieve rapid market adoption of our products and solutions in previously underserved and underpenetrated markets. Our business model and proprietary technologies provide us with a significant and sustainable competitive advantage over incumbents, who we believe are unable to respond effectively due to their higher cost business models.

We offer a broad and expanding portfolio of networking products and solutions and we recently introduced products in the enterprise WLAN, video surveillance, wireless backhaul and machine-to-machine communications markets. Our solutions include systems, high performance radios, antennas and management tools that have been designed to deliver carrier class performance for networking and other applications in the unlicensed RF spectrum. We began shipping embedded radios in fiscal 2006. In fiscal 2008 we introduced a line of products based on 802.11 standard protocols and in early fiscal 2010, we introduced a number of new products based on our proprietary airTechnologies, including our high-performance airMAX platform, which have been rapidly adopted by network operators and high-performance proprietary airMAX service providers. In fiscal 2012 and fiscal 2011, our systems revenue, which primarily consists of our airMAX platform, and to a lesser extent 802.11 standard based systems, accounted for 86% and 81% of our revenues, respectively. Although our airMAX platform has supplanted the demand for some of our 802.11 standard products, we have not experienced a decline in gross margin as we transition from 802.11 standard products to our airMAX platform as they have similar margin profiles. In the future, we expect sales of our airMAX platform products based on our other airTechnologies to continue to represent a growing portion of our revenues and the portion of our revenues derived from our 802.11 standard products to decline as a percentage of total revenues. Our embedded radios bear higher margins than our systems, but we believe that systems present a larger market opportunity.

Building on our leadership in the underserved and underpenetrated segments of the wireless broadband access market, we intend to expand our product offerings in our existing market and enter adjacent markets by relying on the combination of our efficient business model and proprietary technologies. For example, we have introduced products and solutions for the enterprise WLAN, video surveillance, and since late fiscal 2011 licensed microwave wireless backhaul and machine-to-machine communication markets. As we enter such new markets, we plan to leverage existing distributor relationships and establish engaged communities similar to that of the Ubiquiti Community to keep our operating expenses in line with our current model and enable us to offer products in these new markets with compelling price-performance characteristics.

Our revenues increased 79% to $353.5 million in fiscal 2012 from $197.9 million in fiscal 2011. Our revenues increased 44% to $197.9 million in fiscal 2011 from $137.0 million in fiscal 2010.

We had net income (loss) of $102.6 million, $49.7 million and $(5.5) million in fiscal 2012, fiscal 2011 and fiscal 2010, respectively. Our net loss in fiscal 2010 reflected a one-time stock-based compensation charge of $35.9 million related to a repurchase of our common stock and options in connection with the sale of our Series A preferred stock and a $1.6 million charge related to a regulatory export compliance issue.

The Summit Transaction

In March 2010, we sold 33,898,990 shares of our Series A preferred stock and also issued warrants to purchase 2,135,640 shares of our Series A preferred stock to funds affiliated with Summit Partners, L.P. for net proceeds

of $99.5 million. Simultaneously with the issuance of preferred stock and warrants, we repurchased 33,104,320 shares of common stock and canceled and repurchased 794,660 options to purchase common stock from our employees and consultants for aggregate consideration of $100.0 million. In June 2010, the funds affiliated with Summit Partners, L.P., exercised their warrants in full for consideration of $6.3 million. For a more complete description of these transactions see "-Repurchase of Common Stock and Sale of Series A Preferred Stock."

We determined that the per share repurchase price of the common stock and options in March 2010 was above the fair value for shares of our common stock at the time of the repurchase. The fair value was determined to be $1.89, while the repurchase price was $2.95. Therefore, we recognized $35.9 million of the $100.0 million repurchase price as stock-based compensation expense in fiscal 2010. This stock-based compensation was allocated among the various categories of expense in our consolidated statements of operations as follows:

                                                                      Year Ended

Repurchase of Series A Convertible Preferred Stock

In July 2011, we repurchased an aggregate of 12,041,700 shares of our Series A convertible preferred stock from entities affiliated with Summit Partners, L.P. at a price of $8.97 per share for an aggregate consideration of $108.0 million. Of the aggregate purchase price, $40.0 million was paid in cash at the time of closing and the balance of the shares were paid for through the issuance of convertible subordinated promissory notes in the aggregate principal amount of $68.0 million. The $68.0 million was paid down primarily using proceeds from the term loan we executed with East West Bank on September 15, 2011 and funds raised upon the completion of our initial public offering on October 19, 2011.

Initial Public Offering

On October 19, 2011, we completed our initial public offering whereby we sold 2,395,328 shares and selling stockholders sold 4,642,902 shares of our common stock. We received net proceeds of $30.5 million after deducting the underwriting fees and commissions and estimated offering expenses payable by us. Immediately prior to the closing of the initial public offering, all outstanding shares of our Series A convertible preferred stock converted into 23,992,929 shares of our common stock.

Key Components of Our Results of Operations and Financial Condition

Revenues

Our revenues are derived principally from the sale of networking hardware and management tools. In addition, while we do not sell maintenance and support separately, because we have historically included it free of charge in many of our arrangements, we attribute a portion of our systems revenues to this implied post-contract customer support ("PCS").

We classify our revenues into three product categories: systems, embedded radios and antennas/other.

• Systems consists of three product categories:

• Our proprietary airMAX platform products for network operators and service providers;

• Our new platform products which include significant platforms introduced in late fiscal 2011 and during 2012 which includes the UniFi, airVision and airFiber platforms; and

• Other 802.11 standard products including base stations, radios, backhaul equipment and CPE.

• Antennas/other consist of antenna products in the 2.0 to 6.0GHz spectrum, as well as miscellaneous products such as mounting brackets, cables and power over Ethernet adapters. These products include both high performance sector and directional antennas. This category also includes our allocation of revenues to PCS.

We sell substantially all of our products through a limited number of distributors and other channel partners, such as resellers and OEMs. Sales to distributors accounted for 98%, 97% and 93% of our revenues in fiscal 2012, fiscal 2011 and fiscal 2010, respectively. Other channel partners, such as resellers and OEMs, largely accounted for the balance of our revenues. We sell our products without any right of return outside of standard warranty rights.

Cost of Revenues

Our cost of revenues is comprised primarily of the costs of procuring finished goods from our contract manufacturers and chipsets that we consign to certain of our contract manufacturers. In addition, cost of revenues includes tooling, labor and other costs associated with engineering, testing and quality assurance, warranty costs, stock-based compensation and excess and obsolete inventory.

We outsource our manufacturing and order fulfillment and utilize contract manufacturers located primarily in China and, to a lesser extent, Taiwan. We also evaluate and utilize other vendors for various portions of our supply chain from time to time. Our manufacturing organization consists of employees and consultants engaged in the management of our contract manufacturers, new product introduction activities, logistical support and engineering.

Gross Profit

Our gross profit has been, and may in the future be, influenced by several factors including changes in product mix, target end markets for our products, pricing due to competitive pressure, production costs, foreign exchange rates and global demand for electronic components. Although we procure and sell our products in U.S. dollars, our contract manufacturers incur many costs, including labor costs, in other currencies. To the extent that the exchange rates move unfavorably for our contract manufacturers, they may try to pass these additional costs on to us, which could have a material impact on our future average selling prices and unit costs.

Operating Expenses

We classify our operating expenses as research and development and sales, general and administrative expenses.

• Research and development expenses consist primarily of salary and benefit expenses, including stock-based compensation, for employees and costs for contractors engaged in research, design and development activities, as well as costs for prototypes, facilities and travel. Over time, we expect our research and development costs to increase as we continue making significant investments in developing new products and developing new versions of our existing products.

• Sales, general and administrative expenses include salary and benefit expenses, including stock-based compensation, for employees and costs for contractors engaged in sales, marketing and general and administrative activities, as well as the costs of trade shows, marketing programs, promotional materials, bad debt expense, professional services, facilities, general liability insurance and travel. As our product portfolio and targeted markets expand, we may need to employ different sales models, such as building a direct sales force. These sales models would likely increase our costs. Over time, we expect our sales, general and administrative expenses to increase in absolute dollars due to continued growth in headcount, expansion of our registration and defense of trademarks, patents and shareholder litigation efforts and increased support for our business and operations as a public company.

Deferred Revenues and Costs

In the event that collectability of a receivable from products we have shipped is not reasonably assured, we classify those amounts as deferred revenues on our balance sheet until such time as we receive payment of the accounts receivable. We classify the cost of products associated with these deferred revenues as deferred costs of revenues. At June 30, 2012, we did not have any revenue deferred for transactions where we lacked evidence that collectability of the receivables recorded was reasonably assured. At June 30, 2011, $1.2 million of revenue was deferred with a related deferred cost of revenues balance of $881,000.

Also included in our deferred revenues is a portion related to PCS obligations that we estimate we will perform in the future. As of June 30, 2012 and 2011, we had deferred revenues of $805,000 and $497,000 respectively, related to these obligations.

Prepayments

We have historical agreements with certain contract manufacturers whereby we prepay for a portion of the product costs to assure the manufacture and timely delivery of our products. As of June 30, 2012 and 2011, we had prepayment balances of $129,000 and $5.3 million, respectively.

Critical Accounting Policies

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP"). In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP and does not require management's judgment in its application. In other cases, management's judgment is required in selecting among available alternative accounting standards that provide for different accounting treatment for similar transactions. The preparation of consolidated financial statements also requires us to make estimates and assumptions that affect the amounts we report as assets, liabilities, revenues, costs and expenses and affect the related disclosures. We base our estimates on historical experience and other assumptions that we believe are reasonable under the circumstances. In many instances, we could reasonably use different accounting estimates, and in some instances changes in the accounting estimates are reasonably likely to occur from period to period. Accordingly, our actual results could differ significantly from the estimates made by our management. To the extent that there are differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management's judgments and estimates.

Recognition of Revenues

Revenues consist primarily of revenues from the sale of hardware and management tools, as well as the related implied PCS. We recognize revenues when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and the collectability of the resulting receivable is reasonably assured. In cases where we lack evidence that collectability of the resulting receivable is reasonably assured, we defer recognition of revenue until the receipt of cash.

For our sales, evidence of the arrangement consists of an order from a customer. We consider delivery to have occurred once our products have been shipped and title and risk of loss have been transferred. For our sales, these criteria are met at the time the products are transferred to the customer. Our arrangements with customers do not include provisions for cancellation, returns, inventory swaps or refunds that would significantly impact recognized revenues.

We record amounts billed to distributors for shipping and handling costs as revenues. We classify shipping and handling costs incurred by us as cost of revenues.

Deposit payments received from distributors in advance of recognition of revenues are included in current liabilities on our balance sheet and are recognized as revenues when all the criteria for recognition of revenues are met.

Our multi-element arrangements generally include two deliverables. The first deliverable is the hardware and software essential to the functionality of the hardware device delivered at the time of sale. The second deliverable is the implied right to PCS included with the purchase of certain products. PCS is the right to receive, on a when and if available basis, future unspecified software upgrades and features relating to the product's essential software as well as bug fixes, email and telephone support.

We use a hierarchy to determine the allocation of revenues to the deliverables. The hierarchy is as follows: (i) vendor-specific objective evidence of fair value ("VSOE"), (ii) third-party evidence of selling price ("TPE"), and
(iii) best estimate of the selling price ("BESP").

(i) VSOE generally exists only when a company sells the deliverable separately and is the price actually charged by the company for that deliverable. Generally we do not sell the deliverables separately and, as such, do not have VSOE.

(ii) TPE can be substantiated by determining the price that other parties sell similar or substantially similar offerings. We do not believe that there is accessible TPE evidence for similar deliverables.

(iii) BESP reflects our best estimates of what the selling prices of elements would be if they were sold regularly on a stand-alone basis. We believe that BESP is the most appropriate methodology for determining the allocation of revenues among the multiple elements.

We have allocated revenues between these two deliverables using the relative selling price method which is based on the BESP for all deliverables. Revenues allocated to the delivered hardware and the related essential software are recognized at the time of sale provided the other conditions for recognition of revenues have been met. Revenues allocated to the PCS are deferred and recognized on a straight-line basis over the estimated life of each of these devices which currently is two years. All costs of revenues, including estimated warranty costs, are recognized at the time of sale. Costs for research and development and sales and marketing are expensed as incurred. If the estimated life of the hardware product should change, the future rate of amortization of the revenues allocated to PCS would also change.

Our process for determining BESP for deliverables involves multiple factors that may vary depending upon the unique facts and circumstances related to each deliverable. For PCS, we believe our network operators and service providers would be reluctant to pay for such services separately. This view is primarily based on the fact that unspecified upgrade rights do not obligate us to provide upgrades at a particular time or at all, and do not specify to network operators and service providers which upgrades or features will be delivered. We believe that the relatively low prices of our products and our network operators, and service providers' price sensitivity would add to their reluctance to pay for PCS. Therefore, we have concluded that if we were to sell PCS on a stand-alone basis, the selling price would be relatively low.

Key factors considered by us in developing the BESP for PCS include reviewing the activities of specific employees engaged in support and software development to determine the amount of time that is allocated to the development of the undelivered elements, determining the cost of this development effort, and then adding an appropriate level of gross profit to these costs.

Inventory

Our inventories are primarily raw materials, which we have consigned to our contract manufacturers, and to a lesser extent, finished goods. Our inventories are stated at the lower of cost or market value on a first-in, first-out basis. We reduce the value of our inventory for estimated obsolescence or lack of marketability by the difference between the cost of the affected inventory and the estimated market value. Allowances, once established, are not reversed until the related inventory has been subsequently sold or scrapped.

Product Warranties

We offer warranties on certain products and record a liability for the estimated future costs associated with potential warranty claims. These warranty costs are reflected in our consolidated statement of operations within cost of revenues. Our warranties are in effect for 12 months from the distributors' purchase date of the product. Our estimates of future warranty costs are largely based on historical experience of product failure rates, material usage and service delivery costs incurred in correcting product failures. Our operating results could be materially and adversely affected if future warranty claims exceed historical experiences and we are not able to recover costs from our contract manufacturers.

Allowance for Doubtful Accounts

We record an allowance for doubtful accounts for estimated probable losses on uncollectible accounts receivable. In estimating the allowance, management considers, among other factors, the aging of the accounts receivable, our historical write offs, the credit worthiness of each distributor based on payment history and general economic conditions.

Income Taxes

We account for income taxes in accordance with accounting guidance which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in our financial statements or tax returns. Deferred tax assets and liabilities are determined based on the temporary difference between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We establish valuation allowances when necessary to reduce deferred tax assets to the amount we expect to realize. The assessment of whether or not a valuation allowance is required often requires significant judgment including current operating results, the forecast of future taxable income and ongoing prudent and feasible tax planning initiatives.

In addition, our calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations. We may be subject to income tax audits in each of the jurisdictions in which we operate and, as a result, must also assess exposures to any potential issues arising from current or future audits of current and prior years' tax returns. Accordingly, we must assess such potential exposures and, where necessary, provide a reserve to cover any expected loss. To the extent that we establish a reserve, our provision for income taxes would be increased. We review our potential liabilities periodically and, if necessary, record an additional charge in our provision for taxes in the period in which we determine that tax liability is greater than our original estimate. If we ultimately determine that payment of these amounts is unnecessary, we reverse the liability and recognize a tax benefit during the period in which we determine that the liability is no longer necessary.

Stock-based Compensation

We record stock-based awards at fair value as of the grant date and recognize expense ratably on a straight-line basis over the requisite service period, which is generally the vesting term of the awards. We estimate the fair value of stock option awards on the grant date using the Black-Scholes option pricing model. Restricted stock units are valued based on the fair value of our common stock on the date of grant. We adopted the above guidance using the modified prospective transition method. Under this transition method, the new fair value recognition provisions are applied to option grants on and after July 1, 2005. We expense all stock-based awards granted or modified after July 1, 2005 on a straight-line basis.

For grants made since January 1, 2010, we obtained contemporaneous valuation analyses prepared by an unrelated third party valuation firm in order to assist us in determining the fair value of our common stock. The initial contemporaneous valuation report valued our common stock as of April 30, 2010 and we received the most recent contemporaneous valuation report as of July 31, 2011. Prior to January 1, 2010, we obtained retrospective analyses prepared by the same valuation firm in order to assist us in determining the fair value of

our common stock as of June 30, 2009. After January 1, 2010, our board of directors has considered these reports when determining the fair value of our common stock and related exercise prices of option awards on the date such awards were granted.

These third party valuations were also used for purposes of determining the Black-Scholes fair value of our stock option awards and related stock-based compensation expense. Beginning with our initial public offering on October 14, 2011, the fair value of our common stock is determined using the market price of our common stock as of the date of grant.

Repurchase of Common Stock and Options and Sale of Series A Preferred Stock

In March 2010, we entered into a Stock Purchase and Recapitalization Agreement with entities affiliated with Summit Partners, L.P., certain of our stockholders and certain of our optionees pursuant to which we repurchased shares of our common stock and vested options to acquire shares of our common stock from our stockholders and optionees and issued shares of our Series A convertible preferred stock, or the Series A shares, to entities affiliated with Summit Partners, L.P. Upon the closing of the transactions contemplated by the Stock Purchase and Recapitalization Agreement, we simultaneously repurchased an aggregate of 33,104,320 shares of our common stock at $2.95 per share from certain of our employees and consultants and repurchased and subsequently cancelled options to purchase an aggregate of 794,660 shares of our common stock for $2.95 per share from our employees and we issued an aggregate of 33,898,990 Series A shares and warrants to purchase an additional 2,135,640 Series A shares.

We determined by way of historical valuation that the fair market value of each share of our common stock outstanding and subject to outstanding options that we repurchased was $1.89, or $1.06 per share less than the per share repurchase price. As each person from whom we repurchased common stock or options was our employee or consultant, at the time of the repurchase or prior to that time, we recorded approximately $35.9 million as compensation expense, which represented . . .
