Organization and Summary of Significant Accounting Policies. | Note 1. Organization and Summary of Significant Accounting Policies. Organization and Nature of Operations. Adesto Technologies Corporation (together with its subsidiaries; “Adesto”, “we”, “our”, “us” or the “Company”) was incorporated in the state of California in January 2006 and reincorporated in Delaware in October 2015. We are a leading provider of application-specific, feature-rich, ultra-low power non-volatile memory (“NVM”) products. Our corporate headquarters are located in Sunnyvale, California. On September 28, 2012, we purchased certain flash memory product assets from Atmel Corporation and our financial results include the operating results of those assets from the date of acquisition. The Company completed its initial public offering of common stock on October 30, 2015. The Company sold 5,192,184 shares, including 192,194 shares for the underwriters’ option to purchase additional shares. The shares were sold at an initial public offering price of $5.00 per share for net proceeds of $22.2 million to the Company, after deducting underwriting discounts and commissions and offering expenses. See Note 14, Subsequent Events for additional information. Basis of Presentation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP to complete annual financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary to present fairly the financial position of the Company and its results of operations and cash flows for the interim periods presented have been included. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015, for any other interim period or for any other future year. The condensed consolidated balance sheet as of December 31, 2014 was derived from the audited consolidated financial statements as of that date, but does not include all of the disclosures required by U.S. GAAP. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s final prospectus filed pursuant to Rule 424(b) under the Securities Act of 1933, as amended, with the Securities and Exchange Commission (“SEC”) on October 27, 2015. There have been no significant changes in the Company’s accounting policies from those disclosed in its prospectus filed with SEC on October 27, 2015. Reverse Stock Split. On October 1, 2015, we effected a 1-for-33 reverse stock split of our common stock and convertible preferred stock (collectively, “Capital Stock”). On the effective date of the reverse stock split, (i) each 33 shares of outstanding Capital Stock were reduced to one share of Capital Stock; (ii) the number of shares of Capital Stock into which each outstanding warrant or option to purchase Capital Stock is exercisable were proportionately reduced on a 33-to-1 basis; (iii) the exercise price of each outstanding warrant or option to purchase Capital Stock were proportionately increased on a 1-to-33 basis; and (iv) each 33 shares of authorized Capital Stock were reduced to one share of Capital Stock. All of the share numbers, share prices, and exercise prices have been adjusted, on a retroactive basis, to reflect this 1-for-33 reverse stock split. The par value of the common stock and convertible preferred stock were not adjusted as a result of the reverse stock split. Use of Estimates. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the reported amount of assets, liabilities, revenue and expenses and related disclosures of contingent assets and liabilities. On an on-going basis, we evaluate those estimates, including those related to allowances for doubtful accounts, reserves for sales, warranty accrual, inventory write-downs, valuation of long-lived assets, including property and equipment and identifiable intangible assets and goodwill, loss on purchase commitments, valuation of deferred taxes and contingencies. In addition, we use assumptions when employing the Black-Scholes option-pricing model to calculate the fair value of stock options granted and to estimate the carrying value of our convertible preferred stock warrant liability. We base our estimates of the carrying value of certain assets and liabilities on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, when these carrying values are not readily available from other sources. Actual results could differ from these estimates. Revenue Recognition and Accounts Receivable Allowances. We recognize revenue from product sales when persuasive evidence of an arrangement exists, the selling price is fixed or determinable, transfer of title occurs, and the collectibility of the resulting receivable is reasonably assured. Generally, we meet product sale revenue recognition conditions upon shipment because, in most cases, title and risk of loss passes to the customer at that time. In addition, we estimate and record provisions for future returns and other charges against revenue at the time of shipment, consistent with the terms of sale. We sell products to distributors at the price listed in our distributor price book. At the time of sale, we record a sales reserve for ship from stock and debits (“SSDs”), stock rotation rights and any special programs approved by management. We offset the sales reserve against recorded revenues, producing the revenue amount reported in our condensed consolidated statements of operations. The market price for our products can differ significantly from the book price at which we sold the product to the distributor. When the market price of a particular distributor’s sales opportunity to their customers would result in low or negative margins for the distributor, as compared to our original book price, we negotiate SSDs with the distributor. Management analyzes our SSD history to develop current SSD rates that form the basis of the SSD revenue reserve recorded each period. We obtain the historical SSD rates from the distributor’s records and our internal records. We typically grant payment terms of between 30 and 60 days to our customers. Our customers generally pay within those terms. Distributors are invoiced for shipments at listed book price. When the distributors pay the invoice, they may claim debits for SSDs previously authorized by us when appropriate. Once claimed, we process the requests against prior authorizations and adjust reserves previously established for that customer. The revenue we record for sales to our distributors is net of estimated provisions for these programs. Determining net revenue requires significant judgments and estimates on our part. We base our estimates on historical experience rates, the levels of inventory held by our distributors, current trends and other related factors. Because of the inherent nature of estimates, there is a risk actual amounts may differ materially from our estimates. Our consolidated financial condition and operating results depend on our ability to make reliable estimates. We believe that such estimates are reasonable. We also monitor collectibility of accounts receivable primarily through review of our accounts receivable aging. When facts and circumstances indicate the collection of specific amounts or from specific customers is at risk, we assess the impact on amounts recorded for bad debts and, if necessary, record a charge in the period such determination is made. As of September 30, 2015 and December 31, 2014, there was no allowance for doubtful accounts. Concentration of Risk. Our products are primarily manufactured, assembled and tested by third-party foundries and other contractors in Asia and we are heavily dependent on a single foundry in Taiwan for the manufacture of wafers and a single contractor in the Philippines for assembly and testing of our products. We do not have long-term agreements with either of these suppliers. A significant disruption in the operations of either of these parties would adversely impact the production of our products for a substantial period of time, which could have a material adverse effect on our business, financial condition, operating results and cash flows. Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents and accounts receivables. We place substantially all of our cash and cash equivalents on deposit with a reputable, high credit quality financial institution in the United States of America. We believe that the bank that holds substantially all of our cash and cash equivalents is financially sound and, accordingly, subject to minimal credit risk. Deposits held with the bank may exceed the amount of insurance provided on such deposits. We generally do not require collateral or other security in support of accounts receivable. We periodically review the need for an allowance for doubtful accounts by considering factors such as historical experience, credit quality, the age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay. As a result of our favorable collection experience and customer concentration, there was no allowance for doubtful accounts as of September 30, 2015 and December 31, 2014. Customer concentrations as a percentage of total revenue were as follows: Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 Customer A 13 % 26 % 14 % 23 % Customer B 12 % 11 % 10 % * Customer C * 12 % * 16 % Customer D 12 % * * * Customer E 11 % * * * * less than 10% Customer concentrations as a percentage of gross accounts receivable were as follows: September 30, December 31, 2015 2014 Customer A 14 % 20 % Customer B 16 % 15 % Customer C * 10 % Customer D 10 % * * less than 10% Recent Accounting Pronouncements. In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2014-15, Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern. The amendments require management to perform interim and annual assessments of an entity’s ability to continue as a going concern and provide guidance on determining when and how to disclose going concern uncertainties in the financial statements. ASU 2014-15 applies to all entities and is effective for annual and interim reporting periods ending after December 15, 2016, with early adoption permitted. We are currently evaluating the impact that this new guidance will have on our condensed consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09 that requires companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. It also requires enhanced disclosures about revenue, provides guidance for transactions that were not previously addressed comprehensively and improves guidance for multiple-element arrangements. The guidance applies to any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards. In July 2015, the FASB voted to defer the effective date of this guidance until January 1, 2018, with early adoption permitted beginning January 1, 2017. We are currently evaluating the impact of adopting this guidance on our condensed consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs”, which simplifies the presentation of debt issuance costs. ASU 2015-03 is effective for annual reporting periods beginning after December 15, 2015 and interim periods within those years, with early adoption permitted. We are currently evaluating the impact of adoption this guidance on our condensed consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory”, (“ASU 2015-11”), which affects reporting entities that measure inventory using first-in, first-out (FIFO) or average cost. Specifically, ASU 2015-11 requires that inventory be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using last-in, first-out (LIFO) or the retail inventory method. The amendments in this Update are effective for us on September 30, 2017, and early adoption is permitted. We are currently evaluating the impact of adoption this guidance on our condensed consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, “Balance Sheet Classification of Deferred Taxes”. The new standard will require that all deferred tax assets and liabilities be classified as non-current. The new standard is effective for annual period beginning after December 15, 2017, though early adoption is permitted as of the beginning of an earlier interim or annual reporting period. We are currently evaluating the impact of adoption this guidance on our condensed consolidated financial statements. |

Fair Value Measurements. | Note 3. Fair Value Measurements. Fair value is defined as the exchange price that would be received from selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We measure financial assets and liabilities, which consist of convertible preferred stock warrant liability, at fair value at each reporting period using a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value: Level 1 Level 2 Level 3 Financial liabilities measured at fair value on a recurring basis were as follows: Fair Value Measurement at Reporting Date Using Quoted Prices in Active Markets Significant Significant (Level 3) Total (in thousands) As of September 30, 2015 Liabilities: Preferred stock warrant liability $ — $ — $ 463 $ 463 As of December 31, 2014 Liabilities: Preferred stock warrant liability $ — $ — $ 122 $ 122 As of December 31, 2014, we used the Black-Scholes option pricing model to determine the fair value of the warrants to purchase preferred stock (“preferred stock warrants”), including the consideration of underlying common stock price, a risk-free interest rate, expected term and expected volatility. Certain inputs used in the model are unobservable. The fair values could change significantly based on future market conditions. The following table presents quantitative information about the inputs used for our fair value measurements classified in Level 3 of the fair value hierarchy as of December 31, 2014: Year Ended December 31, 2014 Volatility 40 % Expected dividend yield — Risk-free rate 1.74 % Expected term (in years) 6 As of September 30, 2015, we valued our preferred stock warrants using the probability-weighted expected return method (“PWERM”) whereby the value of the various classes of securities are estimated based upon the analysis of future values for us assuming various possible future liquidity events such as an “IPO”, sale or merger. Share value is based upon the probability-weighted present value of expected future net cash flows, considering each of the possible future events, as well as the rights and preferences of each share class. The PWERM was selected due to our established nature, the prospect of a near term exit via an initial public offering (“IPO”) or sale, and our ability to reasonably forecast financial performance. First, we considered the most likely future liquidity event scenarios to be used in the PWERM analysis. Those scenarios were selected to be (i) an IPO completed on October 31, 2015, (ii) an IPO completed on January 31, 2016, (iii) a sale completed on March 31, 2016, (iv) an orderly liquidation completed on December 31, 2016. The probability applied to each scenario was estimated by the board of directors to be 60%, 20%, 10%, and 10%, respectively. Second, our future total equity values for the IPO scenarios were estimated using our prospective cash flows and the application of a next-twelve-month (“NTM”) revenue multiple of 1.8x and 1.9x based on a review of selected similar guideline public companies. Our future total equity values for the sale scenarios were estimated using our prospective cash flows and the application of a last-twelve-month (“LTM”) revenue multiple of 2.5x based on a review of selected similar M&A transactions. Our future total equity value for the orderly liquidation scenario was based upon an asset approach, where the value of our assets and liabilities were adjusted based on estimated salvage values in an orderly liquidation. For each scenario, the values of cash and debt were adjusted to expected balances as of the liquidity date for each scenario. Third, the future total equity value for each scenario was bifurcated to each class of security based upon their respective rights and preferences. Security classes included convertible preferred stock (by seniority), outstanding warrants to purchase convertible preferred stock, common stock, and outstanding options to purchase common stock. Under the IPO scenarios, the convertible preferred stock was assumed to automatically convert to common stock without receiving a liquidation preference. Under the sale scenarios, the convertible preferred stock was assumed to receive its respective liquidation preferences and then participate with the common stock on a pro rata basis on any remaining distributions with no cap on participation. The total distributions to common stock were aggregated under each scenario and divided by the total shares of common stock outstanding to determine the share value for the common stock at the subject liquidity date. Fourth, the concluded share values for the common stock for each scenario were then discounted to present value using a reasonable rate of return applicable to our prospective risks. The concluded discount rate of 23.6% was based on an application of the weighted average cost of capital (“WACC”) using the capital asset pricing method (“CAPM”). Lastly, we estimated the discount for lack of marketability (“DLOM”) to be applied to the shares of common stock. The DLOM reflects the lower value placed on securities that are not freely transferable, as compared to those that trade frequently in established markets. The DLOMs were estimated using the protective put method and ranged between 2% to 5%, depending on the scenario. In addition, in order to estimate warrant liabilities, preferred stock warrants were also valued using the above methodologies and assumptions. It should be noted that, prior to an IPO or sale, no future financing rounds are expected. The assumptions underlying these valuations represent management’s best estimates, which involve inherent uncertainties and the application of management judgment. As a result, if factors or expected outcomes change and we use significantly different assumptions or estimates, the valuation of our equity-based compensation could be materially different. The key subjective factors and assumptions used in our valuation of as of September 30, 2015 primarily consisted of: • the probability and timing of the various possible liquidity scenarios; • the estimate of prospective cash flows leading up to each liquidity scenario; • the selection of LTM and NTM revenue multiples based on a review of selected similar guideline public company and M&A transaction data; • the estimated rate of return using the WACC; and • the estimated DLOM. The following table sets forth a reconciliation the changes in fair value of preferred stock warrants during the nine months ended September 30, 2015 (in thousands): Balance as of December 31, 2014 $ 122 Issuance of preferred stock warrants 863 Change in fair value of preferred stock warrants (522 ) Balance as of September 30, 2015 $ 463 As of December 31, 2014 and September 30, 2015, we did not have any assets that are measured at fair value on a recurring basis. |

Borrowings. | Note 5. Borrowings. Bridge Bank Loan. In October 2013, we entered into the Business Financing Agreement (the “BFA”) with Bridge Bank N.A. The agreement consisted of both a revolving credit facility under which we were permitted to borrow up to 80% of eligible accounts receivable but not to exceed $7.5 million and a term loan in the amount of $9.0 million. Interest on the revolving credit facility accrued at the bank’s prime rate, which under the BFA could not have been less than 3.25%, plus 1.25% while interest on the term loan accrues at the bank’s prime rate plus 3%. Under the term loan, we were required to make interest only payments through April 2014 and principal payments of $300,000 monthly thereafter plus interest. Borrowings under the BFA were secured by all of our assets and are subject to certain financial covenants, including maintaining minimum levels of EBITDA on a quarterly basis and a certain minimum asset coverage ratio based on the ratio of unrestricted cash plus certain accounts receivable to total outstanding under the BFA. In 2014, we were not in compliance with certain financial covenants under the BFA. As a result, in October 2014, we entered into the First Business Financing Modification Agreement (the “BFA Modification”) under which the covenant defaults were waived. The BFA Modification (i) increased the interest rate charged on the term loan from the bank’s prime rate plus 3% to the bank’s prime rate plus 4% and would have declined to the bank’s prime rate plus 3% upon the raising of additional equity of not less than $2.5 million, (ii) required us to continue to maintain certain minimum levels of EBITDA and asset coverage ratios, (iii) required us to maintain unrestricted cash of not less than $4.25 million until that point at which we either receive additional equity of not less than $5.0 million or maintain a debt service coverage ratio of not less than 1.00 to 1.00 (based on the ratio of EBITDA to current portion of total amounts outstanding under the BFA Modification plus period-to-date interest expense payments) for two consecutive quarters. Under the BFA the bank was paid a facility fee of $82,500 at closing. Under the BFA Modification, the bank was paid an additional facility fee of $50,000 and received a warrant to purchase 1,488 shares of our Series E convertible preferred stock. The facility fees and the value of the warrant, $0.1 million, were recorded as debt discount and have been amortized over the life of the agreement. Amortization of debt discount was immaterial during 2013 and $0.1 million in 2014. As of December 31, 2014, the remaining unamortized debt discount was $0.1 million. As of December 31, 2014 we were not in compliance with the financial covenants of the agreements and all amounts due under the agreement are shown as current on the consolidated balance sheets. Borrowings of $10.9 million under this facility were repaid in full in April 2015. Opus Bank Term Loan. In April 2015, we entered into a three-year $15.0 million credit agreement with Opus Bank, which replaced the BFA, as amended. The agreement provides for a senior secured term loan facility, in an aggregate principal amount of up to $15.0 million to be used for general corporate purposes including working capital, to repay certain indebtedness and for capital expenditures and other expenses. Interest will accrue on any outstanding borrowings at a rate equal to (a) the higher of (i) the prime rate (as publicly announced from time to time by the Wall Street Journal) and (ii) 3.25% plus (b) (i) 1.00% if our cash and cash equivalents are greater than 125% of the outstanding principal of our borrowings under the new term loan facility, or (ii) 2.00% if our cash and cash equivalents are less than or equal to 125% of such borrowings. Indebtedness we incur under this agreement is secured by substantially all of our assets and contains financial covenants requiring us to maintain a monthly asset coverage ratio of not less than 1.00 to 1.00 through September 30, 2015 and 1.10 to 1.00 thereafter, and quarterly adjusted EBITDA (measured on a trailing three-month basis) of $1 through March 31, 2016 and increasing to higher levels thereafter. The agreement contains customary affirmative and negative covenants, including covenants that limit or restrict our ability to, among other things, incur additional indebtedness, grant liens, make investments, repurchase stock, pay dividends, transfer assets, merge or consolidate and make acquisitions. As of September 30, 2015, we were not in compliance with all financial covenants and received from the bank a waiver for non-compliance and restrictions. As of September 30, 2015 we had borrowings of $15.0 million outstanding prior to accounting for debt discount. We may not draw additional funds under the new term loan facility and our borrowings mature on April 30, 2018. In connection with the new term loan facility, the bank received a warrant to purchase 31,897 shares of Series E convertible preferred stock. In addition, we paid financing costs of $0.1 million. The financing costs and the value of the warrant, $0.9 million, were recorded as debt discount and are being amortized over the life of the agreement. Amortization of debt discount was $0.2 million during the nine months ended September 30, 2015. As of September 30, 2015, the remaining unamortized debt discount was $0.7 million. Outstanding borrowings consisted of the following (in thousands): September 30, December 31, 2015 2014 Revolving line of credit $ — $ 4,273 Term loan, current 5,042 6,476 Term loan, non-current 9,229 — Total $ 14,271 $ 10,749 Future repayments on outstanding borrowings (excluding unamortized discount of $0.7 million as of September 30, 2015) are as follows (in thousands): Year ending December 31, 2015 (remaining 3 months) $ 1,000 2016 6,000 2017 6,000 2018 2,000 $ 15,000 Interest expense incurred for the three and nine months ended September 30, 2015 was $0.3 million and $0.8 million, respectively. Interest expense incurred for the three and nine months ended September 30, 2014 was $0.2 million and $0.6 million, respectively. |

Although we are not currently subject to any litigation, and no litigation is currently threatened against us, we may be subject to legal proceedings, claims and litigation, including intellectual property litigation, arising in the ordinary course of business. Such matters are subject to many uncertainties and outcomes and are not predictable with assurance. We accrue amounts that we believe are adequate to address any liabilities related to legal proceedings and other loss contingencies that we believe will result in a probable loss that is reasonably estimable. Indemnification . During the normal course of business, we may make certain indemnities, commitments and guarantees which may include intellectual property indemnities to certain of our customers in connection with the sales of our products and indemnities for liabilities associated with the infringement of other parties’ technology based upon our products. Our exposure under these indemnification provisions is generally limited to the total amount paid by a customer under the agreement. However, certain agreements include indemnification provisions that could potentially expose us to losses in excess of the amount received under the agreement. In addition, we indemnify our officers, directors and certain key employees while they are serving in good faith in such capacities. We have not recorded any liability for these indemnities, commitments and guarantees in the accompanying consolidated balance sheets. Where necessary, we accrue for losses for any known contingent liabilities, including those that may arise from indemnification provisions, when future payment is probable. |

Thereafter, any remaining assets available for distribution would be distributed on a pro rata basis to the holders of preferred stock (on an as converted basis) and common stock based on the number of shares of common stock held by each stockholder. If upon liquidation, our assets are not sufficient to permit payment of the full liquidation preference of the preferred stock, the assets will be distributed first to the holders of Series E on a pro rata basis based on the number of shares held by each Series E stockholder, then the Management Carve-out Payments, then to the Series D and Series D-1 together on a pro rata basis, and then sequentially to each of the Series C, Series B and series A on a pro rata basis until all assets have been distributed. Voting. Conversion. Each share of Series A, Series B, Series C, Series D and Series D-1 will automatically convert at the then-effective conversion rate into shares of common stock upon the closing of a firm commitment underwritten initial public offering pursuant to an effective registration statement under the Securities Act of 1933, with gross proceeds to us of not less than $20 million (“qualified IPO”), and each share of Series E will automatically convert on a 1-to-9.8841 basis in the event of a qualified IPO. In addition, each share of preferred stock will automatically convert at the then-effective conversion ratio into shares of common stock upon receipt by us of a written request for such conversion from the holders of (a) 90% of the Series E and (b) two-thirds of each other series of preferred stock.

In January 2015, this warrant expired unexercised. In connection with a capital lease financing in February 2010, we issued a warrant to purchase 7,378 shares of Series B at $12.1968 per share. The warrants are exercisable any time at the option of the holder and expire at the earlier of February 2017, an initial public offering, or an acquisition. This warrant was initially valued at $57,000 and recorded as a liability. In connection with a term loan financing with Opus Bank, in September 2012 we issued a warrant to purchase 35,885 shares of Series D at a price per share of $31.35. In addition, in connection with a first amendment of the term loan financing with Opus Bank, on each of March 31, 2013 and June 30, 2013 we issued to Opus Bank a warrant to purchase 17,942 shares of Series D at a price per share of $31.35. The warrants were exercisable any time at the option of the holder and expire at the earlier of September 2019, an initial public offering, or an acquisition. The warrants were initially valued at $1.3 million and recorded as a liability. In connection with a BFA Modification agreement with Bridge Bank, in October 2014 we issued a warrant to purchase 1,488 shares of Series E at a price per share of $23.5125. The warrant was exercisable any time at the option of the holder and expires at the earlier of October 2024, an initial public offering, or an acquisition. The warrant was initially valued at $0.1 million and recorded as a liability. Concurrent with the close of our initial public offering on October 30, 2015, all preferred stock warrants were converted into warrants to purchase a total of 411,499 shares of common stock and accordingly, the liability was reclassified to additional paid-in capital. As of December 31, 2014 and September 30, 2015, the fair value of preferred stock warrants was $0.1 million and $0.5 million, respectively, and classified as long-term liabilities, as the warrants primarily expire in periods beyond one year from December 31, 2014. The warrants are subject to re-measurement at each balance sheet date with any change in fair value recognized as a component of other income (expense), net in our condensed consolidated statements of operations. During the nine months ended September 30, 2015 and 2014, we recorded income of $0.5 million and $38,000 respectively, for the change in fair value of these warrants. We will continue to adjust the liability for changes in fair value until the earlier of the exercise or expiration of the warrants or the completion of a liquidation event, including the completion of a qualified initial public offering, at which time all preferred stock warrants will be converted into warrants to purchase common stock and, accordingly, the liability will be reclassified to additional paid-in capital. |

We were authorized to issue 6,666,666 shares of common stock with no par value per share as of December 31, 2014 and 14,696,969 shares of common stock with no par value per share as of September 30, 2015. Each holder of common stock is entitled to one vote per share. The holders of common stock are also entitled to receive dividends, when and if declared by our Board of Directors, subject to the consent of two-thirds of the outstanding preferred stock and their preferential dividend rights. Common Stock Reserved for Future Issuance. As of September 30, 2015 and December 31, 2014, we had reserved shares of common stock for future issuances as follows: September 30, December 31, 2015 2014 Preferred stock 9,114,739 9,114,739 Warrants to purchase preferred stock 411,499 86,046 Warrants to purchase common stock 218,618 218,618 Stock option plan: Options outstanding 796,147 604,412 Options available for future grants 1,814,420 148,633 Total 12,355,423 10,172,448 Common Stock Warrants. As of September 30, 2015 and December 31, 2014, outstanding common stock warrants were as follows: Total amount of securities issuable Exercise Price Issuance Date Expiration Date 114,784 $ 1.98 2009 2016 28,696 $ 1.98 2011 2016 75,138 $ 3.96 2011 2018 218,618 Common stock warrants are convertible at the option of the holder any time after the date of issuance into shares of our common stock. The aggregate amount of shares of common stock that would be issued is determined by dividing the exercisable price by the conversion price applicable on the date of conversion multiplied by the number of warrants exercised. When a public market exists for our common stock, the conversion price is equal to certain quoted prices for our common stock five trading days prior to the date of conversion. When no public market exists for our common stock, the fair value is determined by our Board of Directors. When a warrant is exercised in connection with our initial public offering, the conversion price is equal to the per share offering price to the public in the initial public offering. In connection with our initial public offering, on October 30, 2015, all common stock warrants were net exercised based on the initial public offering price of $5.00 per share, resulting in the issuance of 102,289 shares of our common stock. 2007 Equity Incentive Plan. In 2007, our Board of Directors and shareholders approved the 2007 Equity Incentive Plan (the “2007 Plan”) under which 272,727 shares of common stock were reserved and available for the issuance of stock options and restricted stock to eligible participants. The 2007 Plan has been subsequently amended to increase the number of shares of common stock reserved for issuance under the 2007 Plan to 787,878 and during the nine months ended September 30, 2015, the number of shares reserved for issuance under the 2007 Plan has been increased to 2,651,515. Options and restricted stock awards may be granted at a price per share not less than the 85% of the fair value at the date of grant or award, respectively. Restricted stock awarded to persons controlling more than 10% of our stock may be granted at a price per share not less than the 100% of the fair value at the date of the award. Options granted to new employees generally vest over a four-year period with 25% vesting at the end of one year and the remaining to vest monthly thereafter, while options granted to existing employees generally vest over a four-year period. Options granted generally are exercisable up to 10 years. A summary of stock option activity under the 2007 Plan is as follows: Stock Options Shares Weighted- Weighted- Aggregate (aggregate intrinsic value in thousands) Outstanding as of December 31, 2013 565,265 $ 3.60 5.9 $ — Granted 110,085 1.65 Exercised (20,398 ) 1.66 Canceled (50,540 ) 3.96 Outstanding as of December 31, 2014 604,412 $ 1.57 6.8 $ — Granted 201,185 5.15 Exercised (5,954 ) 1.73 Canceled (3,496 ) 1.74 Outstanding as of September 30, 2015 796,147 $ 2.18 6.8 $ 2,245 Options vested and expected to vest as of September 30, 2015 749,276 $ 2.41 6.6 $ 1,941 Options vested and exercisable as of September 30, 2015 500,483 $ 1.70 5.4 $ 1,652 |

Stock-based Compensation. | Note 10. Stock-based Compensation. We record stock-based compensation based on fair value as of the grant date using the Black-Scholes option-pricing model. We recognize such costs as compensation expense on a straight-line basis over the employee’s requisite service period, which is generally four years. Our valuation assumptions are as follows: Fair value of common stock. Risk-free interest rate. Expected term. Volatility. Dividend yield. The following table summarizes the weighted-average assumptions used in the Black-Scholes option-pricing model to determine fair value of stock options: Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 Volatility 40 % 65 % 40 % 65 % Expected dividend yield — — — — Risk-free rate 1.53 % 1.75 % 1.59 % 1.75 % Expected term (in years) 5.90 6.03 5.46 6.03 The following table presents the effects of stock-based compensation during the periods (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 Cost of revenue $ 3 $ 1 $ 6 $ 3 Research and development 26 31 66 72 Sales and marketing 16 17 37 24 General and administrative 40 78 88 105 Total $ 85 $ 127 $ 197 $ 204 We did not realize any income tax benefit from stock option exercises in either of the periods presented due to recurring losses and valuation allowances. As of September 30, 2015, the total unrecognized compensation cost related to stock options, net of estimated forfeitures, was approximately $0.7 million, and this amount is expected to be recognized over a weighted-average period of approximately 2 years. Stock Option Repricing. In August 2014, our Board of Directors approved a common stock option repricing program whereby previously granted and unexercised options held by current employees with exercise prices above $1.65 per share were repriced on a one-for-one basis to $1.65 per share which represented the per share fair value of our common stock as of the date of the repricing. There was no other modification to the vesting schedule of the previously issued options. As a result, 387,749 unexercised options originally granted to purchase common stock at prices ranging from $1.98 to $5.61 per share were repriced under this program. We treated the repricing as a modification of the original awards and calculated additional compensation costs for the difference between the fair value of the modified award and the fair value of the original award on the modification date. The repricing resulted in incremental stock-based compensation expense of $0.2 million. Expense related to vested shares was expensed on the repricing date and expense related to unvested shares is being amortized over the remaining vesting period of such stock options. |

Income Taxes. | Note 11. Income Taxes. We recorded an income tax provision of $5,000 and $76,000 for the three and nine months ended September 30, 2015, respectively, an income tax provision of $15,000 and $125,000 for the three and nine months ended September 30, 2014, respectively. The income tax provision is comprised of estimates of current taxes due in domestic and foreign jurisdictions. The income tax provision reflects tax expense associated with state income tax, foreign taxes, uncertain tax positions and tax expense related to the recording of a deferred tax liability that results from the amortization for income tax purposes of acquisition-related goodwill. The decrease in the tax provision between 2015 and 2014 is primarily due to a decrease in French subsidiary taxes for the both the three and nine month periods. As of September 30, 2015, our deferred tax assets are fully offset by a valuation allowance except in those jurisdictions where it is determined that a valuation allowance is not required. Accounting for income taxes (ASC 740), Income Taxes, provides for the recognition of deferred tax assets if realization of such assets is more likely than not. Based on the weight of available evidence, which includes historical operating performance, reported cumulative net losses since inception and difficulty in accurately forecasting our future results, we provided a full valuation allowance against our net U.S. deferred tax assets. We reassess the need for our valuation allowance on a quarterly basis. If it is later determined that a portion or all of the valuation allowance is not required, it generally will be a benefit to the income tax provision in the period that such determination is made. We evaluate tax positions for recognition using a more-likely-than-not recognition threshold, and those tax positions eligible for recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon the effective settlement with a taxing authority that has full knowledge of all relevant information. We believe that we have provided adequate reserves for our income tax uncertainties in all open tax years. The Company does not anticipate a material change in the total amount or composition of its unrecognized tax benefits within the 12 months of September 30, 2015. We file tax returns in the United States for federal, California, and other states. All tax years remain open to examination for both federal and state purposes as a result of our net operating loss and credit carryforwards. We file foreign tax returns in the United Kingdom, France and China. These tax years remain open to examination. |

Purchase of Serial Flash Memory Product Assets. | Note 13. Purchase of Serial Flash Memory Product Assets. In September 2012, we completed the purchase of the serial flash memory product assets from Atmel Corporation. The aggregate purchase price for these assets was $25.0 million and was accounted for as a business combination. The excess of the purchase price over the fair value allocated to the net assets is goodwill. The key factors attributable to the creation of goodwill by the transaction are synergies in technology, operations, existing customer base and cash flow generated from revenue. The estimated fair value of finite-lived intangible assets and tangible assets were determined as follows (i) customer relationships and customer backlog were determined using the excess earnings approach, (ii) developed technology was determined using the royalty method, (iii) non-compete agreement was determined using the income approach, (iv) inventories were estimated using the cost approach and (v) property and equipment was estimated using replacement value. The following table summarizes the allocation of the purchase price to the tangible and intangible assets purchased as of the date of purchase (in thousands): Finite-lived intangible assets: Developed technology $ 4,282 Customer relationships 9,011 Customer backlog 2,779 Non-compete covenant 282 Total finite-lived intangible assets 16,354 Tangible assets: Inventory 8,365 Property and equipment 259 Total finite-lived intangible assets 8,624 Indefinite-lived intangible asset: Goodwill 22 $ 25,000 |

Subsequent Events. | Note 14. Subsequent Events. Reverse Stock Split On October 1, 2015, we effected a 1-for-33 reverse split of our common stock and convertible preferred stock. Reincorporation On October 9, 2015, we completed our reincorporation in Delaware. Initial Public Offering On October 30, 2015, subsequent to the close of the Company’s third quarter ended September 30, 2015, the Company completed its IPO of 5,192,184 shares common stock, at $5.00 per share, before underwriting discount and commissions. The shares sold included 192,184 shares issued as a result of the underwriters’ exercise of their option to purchase additional shares. The IPO generated net proceeds to the Company of approximately $22.2 million, after deducting underwriting discounts and commissions and offering expenses. Offering costs incurred by the Company were approximately $1.9 million and will be recorded against the proceeds received from the sale of the common stock. All outstanding shares of convertible preferred stock converted into 9,114,739 shares of the Company’s common stock concurrent with the close of the IPO on October 30, 2015. Following the IPO, there were no shares of the Company’s convertible preferred stock outstanding. Amendment of Certificate of Incorporation Upon the filing of our Certificate of Amendment to our Restated Certificate of Incorporation on October 23, 2015, the definition of “qualified IPO” was amended such that each share of Series A, Series B, Series C, Series D and Series D-1 will automatically convert at the then effective conversion rate into shares of common stock upon the closing of a firm commitment underwritten initial public offering pursuant to an effective registration statement under the Securities Act of 1933, with gross proceeds to us of not less than $20 million, and each share of Series E will automatically convert on a 1-to-9.8841 basis in the event of such qualified IPO. Amended and Restated Certificate of Incorporation Upon the filing of our Amended and Restated Certificate of Incorporation upon the closing of our on initial public offering on October 30, 2015, our authorized capital stock consisted of 100,000,000 shares of common stock, $0.0001 par value per share, and 5,000,000 shares of undesignated preferred stock, $0.0001 par value per share. Facility Leases On November 2, 2015, the Company extended the lease for its headquarters by six months to July 2016 by entering into that certain Amendment to Commercial Sublease, dated November 2, 2015, between the Company and eGain Corporation. The Amendment provides for a base rent during the extension period of $47,087 per month. Additionally, on November 2, 2015, the Company entered into a lease with Peterson Ridge LLC pursuant to which the Company has leased a new headquarters facility, consisting of an aggregate of approximately 34,000 square feet of space in Santa Clara, California. The initial term of the lease commenced on November 2, 2015 and is scheduled to end on July 31, 2023 and may be extended, at the Company’s option, for an additional five-year period following the initial lease term. Pursuant to the lease, monthly base rental payments due under the lease are expected to be approximately $93,000 per month between August 1, 2016 and February 27, 2017, with annual increases of approximately 3% thereafter. The Company must also pay for certain other operating costs under the lease, including operating expenses, taxes, assessments, insurance, utilities, securities and property management fees. Peterson Ridge LLC is obligated to reimburse the Company for up to $2,521,051 of the Company’s out-of-pocket costs associated with any tenant improvements, as defined in the lease. |

Basis of Presentation | Basis of Presentation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP to complete annual financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary to present fairly the financial position of the Company and its results of operations and cash flows for the interim periods presented have been included. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015, for any other interim period or for any other future year. The condensed consolidated balance sheet as of December 31, 2014 was derived from the audited consolidated financial statements as of that date, but does not include all of the disclosures required by U.S. GAAP. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s final prospectus filed pursuant to Rule 424(b) under the Securities Act of 1933, as amended, with the Securities and Exchange Commission (“SEC”) on October 27, 2015. There have been no significant changes in the Company’s accounting policies from those disclosed in its prospectus filed with SEC on October 27, 2015. |
Reverse Stock Split. | Reverse Stock Split. On October 1, 2015, we effected a 1-for-33 reverse stock split of our common stock and convertible preferred stock (collectively, “Capital Stock”). On the effective date of the reverse stock split, (i) each 33 shares of outstanding Capital Stock were reduced to one share of Capital Stock; (ii) the number of shares of Capital Stock into which each outstanding warrant or option to purchase Capital Stock is exercisable were proportionately reduced on a 33-to-1 basis; (iii) the exercise price of each outstanding warrant or option to purchase Capital Stock were proportionately increased on a 1-to-33 basis; and (iv) each 33 shares of authorized Capital Stock were reduced to one share of Capital Stock. All of the share numbers, share prices, and exercise prices have been adjusted, on a retroactive basis, to reflect this 1-for-33 reverse stock split. The par value of the common stock and convertible preferred stock were not adjusted as a result of the reverse stock split. |
Use of Estimates. | Use of Estimates. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the reported amount of assets, liabilities, revenue and expenses and related disclosures of contingent assets and liabilities. On an on-going basis, we evaluate those estimates, including those related to allowances for doubtful accounts, reserves for sales, warranty accrual, inventory write-downs, valuation of long-lived assets, including property and equipment and identifiable intangible assets and goodwill, loss on purchase commitments, valuation of deferred taxes and contingencies. In addition, we use assumptions when employing the Black-Scholes option-pricing model to calculate the fair value of stock options granted and to estimate the carrying value of our convertible preferred stock warrant liability. We base our estimates of the carrying value of certain assets and liabilities on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, when these carrying values are not readily available from other sources. Actual results could differ from these estimates. |
Revenue Recognition and Accounts Receivable Allowances | Revenue Recognition and Accounts Receivable Allowances. We recognize revenue from product sales when persuasive evidence of an arrangement exists, the selling price is fixed or determinable, transfer of title occurs, and the collectibility of the resulting receivable is reasonably assured. Generally, we meet product sale revenue recognition conditions upon shipment because, in most cases, title and risk of loss passes to the customer at that time. In addition, we estimate and record provisions for future returns and other charges against revenue at the time of shipment, consistent with the terms of sale. We sell products to distributors at the price listed in our distributor price book. At the time of sale, we record a sales reserve for ship from stock and debits (“SSDs”), stock rotation rights and any special programs approved by management. We offset the sales reserve against recorded revenues, producing the revenue amount reported in our condensed consolidated statements of operations. The market price for our products can differ significantly from the book price at which we sold the product to the distributor. When the market price of a particular distributor’s sales opportunity to their customers would result in low or negative margins for the distributor, as compared to our original book price, we negotiate SSDs with the distributor. Management analyzes our SSD history to develop current SSD rates that form the basis of the SSD revenue reserve recorded each period. We obtain the historical SSD rates from the distributor’s records and our internal records. We typically grant payment terms of between 30 and 60 days to our customers. Our customers generally pay within those terms. Distributors are invoiced for shipments at listed book price. When the distributors pay the invoice, they may claim debits for SSDs previously authorized by us when appropriate. Once claimed, we process the requests against prior authorizations and adjust reserves previously established for that customer. The revenue we record for sales to our distributors is net of estimated provisions for these programs. Determining net revenue requires significant judgments and estimates on our part. We base our estimates on historical experience rates, the levels of inventory held by our distributors, current trends and other related factors. Because of the inherent nature of estimates, there is a risk actual amounts may differ materially from our estimates. Our consolidated financial condition and operating results depend on our ability to make reliable estimates. We believe that such estimates are reasonable. We also monitor collectibility of accounts receivable primarily through review of our accounts receivable aging. When facts and circumstances indicate the collection of specific amounts or from specific customers is at risk, we assess the impact on amounts recorded for bad debts and, if necessary, record a charge in the period such determination is made. As of September 30, 2015 and December 31, 2014, there was no allowance for doubtful accounts. |
Concentration of Risk. | Concentration of Risk. Our products are primarily manufactured, assembled and tested by third-party foundries and other contractors in Asia and we are heavily dependent on a single foundry in Taiwan for the manufacture of wafers and a single contractor in the Philippines for assembly and testing of our products. We do not have long-term agreements with either of these suppliers. A significant disruption in the operations of either of these parties would adversely impact the production of our products for a substantial period of time, which could have a material adverse effect on our business, financial condition, operating results and cash flows. Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents and accounts receivables. We place substantially all of our cash and cash equivalents on deposit with a reputable, high credit quality financial institution in the United States of America. We believe that the bank that holds substantially all of our cash and cash equivalents is financially sound and, accordingly, subject to minimal credit risk. Deposits held with the bank may exceed the amount of insurance provided on such deposits. We generally do not require collateral or other security in support of accounts receivable. We periodically review the need for an allowance for doubtful accounts by considering factors such as historical experience, credit quality, the age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay. As a result of our favorable collection experience and customer concentration, there was no allowance for doubtful accounts as of September 30, 2015 and December 31, 2014. Customer concentrations as a percentage of total revenue were as follows: Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 Customer A 13 % 26 % 14 % 23 % Customer B 12 % 11 % 10 % * Customer C * 12 % * 16 % Customer D 12 % * * * Customer E 11 % * * * * less than 10% Customer concentrations as a percentage of gross accounts receivable were as follows: September 30, December 31, 2015 2014 Customer A 14 % 20 % Customer B 16 % 15 % Customer C * 10 % Customer D 10 % * * less than 10% |
Recent Accounting Pronouncements. | Recent Accounting Pronouncements. In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2014-15, Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern. The amendments require management to perform interim and annual assessments of an entity’s ability to continue as a going concern and provide guidance on determining when and how to disclose going concern uncertainties in the financial statements. ASU 2014-15 applies to all entities and is effective for annual and interim reporting periods ending after December 15, 2016, with early adoption permitted. We are currently evaluating the impact that this new guidance will have on our condensed consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09 that requires companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. It also requires enhanced disclosures about revenue, provides guidance for transactions that were not previously addressed comprehensively and improves guidance for multiple-element arrangements. The guidance applies to any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards. In July 2015, the FASB voted to defer the effective date of this guidance until January 1, 2018, with early adoption permitted beginning January 1, 2017. We are currently evaluating the impact of adopting this guidance on our condensed consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs”, which simplifies the presentation of debt issuance costs. ASU 2015-03 is effective for annual reporting periods beginning after December 15, 2015 and interim periods within those years, with early adoption permitted. We are currently evaluating the impact of adoption this guidance on our condensed consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory”, (“ASU 2015-11”), which affects reporting entities that measure inventory using first-in, first-out (FIFO) or average cost. Specifically, ASU 2015-11 requires that inventory be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using last-in, first-out (LIFO) or the retail inventory method. The amendments in this Update are effective for us on September 30, 2017, and early adoption is permitted. We are currently evaluating the impact of adoption this guidance on our condensed consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, “Balance Sheet Classification of Deferred Taxes”. The new standard will require that all deferred tax assets and liabilities be classified as non-current. The new standard is effective for annual period beginning after December 15, 2017, though early adoption is permitted as of the beginning of an earlier interim or annual reporting period. We are currently evaluating the impact of adoption this guidance on our condensed consolidated financial statements. |
