1.                       Description of Business and Basis of Presentation

Pandora Media, Inc. (the “Company” or “Pandora”) provides an internet radio service in the United States, offering a personalized experience for each of its listeners. The Company has developed a form of radio that uses intrinsic qualities of music to initially create stations that then adapt playlists in real-time based on the individual feedback of each listener.

The Company was incorporated as a California corporation in January 2000 and reincorporated as a Delaware corporation in December 2010.

Basis of Presentation

The interim unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. In the opinion of the Company’s management, the interim unaudited condensed consolidated financial statements include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of the Company’s financial position for the periods presented. These interim unaudited condensed consolidated financial statements are not necessarily indicative of the results expected for the full fiscal year or for any subsequent period and should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended January 31, 2013.

Certain changes in presentation have been made to conform prior period presentation to current period reporting of the Company’s content acquisition costs which are now included as a separate line item component of Cost of Revenue in the Company’s Statement of Operations.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. Estimates are used for determining selling prices for elements sold in multiple-element arrangements, the allowance for doubtful accounts, stock-based compensation, fair values of investments, income taxes, and accrued royalties. To the extent there are material differences between these estimates, judgments, or assumptions and actual results, the Company’s financial statements could be affected. In many cases, the accounting treatment of a particular transaction is specifically dictated by U.S. GAAP and does not require management’s judgment in its application. There are also areas in which management’s judgment in selecting among available alternatives would not produce a materially different result.

Fiscal Year

All references herein to a fiscal year refer to the 12 months ended January 31 of such year, and references to the first, second, third and fourth fiscal quarters refer to the three months ended April 30, July 31, October 31 and January 31, respectively.

2.                       Summary of Significant Accounting Policies

There have been no material changes to the Company’s significant accounting policies as compared to those described in the Company’s Annual Report on Form 10-K for the fiscal year ended January 31, 2013.

Concentration of Credit Risk

For the three months ended April 30, 2012 and 2013, the Company had no customers that accounted for more than 10% of the Company’s total revenue.

As of January 31 and April 30, 2013, the Company had no customers that accounted for more than 10% of the Company’s total accounts receivable.

Recently Issued Accounting Standards

In February 2013, the FASB issued an update to the reporting of reclassifications out of accumulated other comprehensive income. The guidance requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under GAAP to be reclassified in its entirety to net income. For other amounts that are not required under GAAP to be reclassified in their entirety from accumulated other comprehensive income to net income in the same reporting period, an entity is required to cross-reference other disclosures required under GAAP that provide additional detail about those amounts. In the three months ending April 30, 2013, the Company adopted this guidance, which is related to disclosure only. The Company had no  reclassifications out of accumulated other comprehensive income as of April 30, 2013.

3.                       Composition of Certain Financial Statement Captions

Cash, Cash Equivalents and Short-term Investments

Cash, cash equivalents and short-term investments consisted of the following:

The Company’s short-term investments have maturities of less than 12 months and are classified as available for sale. As of January 31 and April 30, 2013 the cost basis of the Company’s cash and cash equivalents approximated their fair values and as a result, no unrealized gains or losses were recorded as of January 31 and April 30, 2013.

The following tables summarize the Company’s available-for-sale securities’ adjusted cost, gross unrealized gains, gross unrealized losses and fair value by significant investment category as of January 31 and April 30, 2013 (in thousands).

The Company’s investment policy requires investments to be investment grade, primarily rated “A1” by Standard & Poor’s or “P1” by Moody’s or better for short-term investments, with the objective of minimizing the potential risk of principal loss. In addition, the investment policy limits the amount of credit exposure to any one issuer.

Table of Contents

Pandora Media, Inc.

Notes to Condensed Consolidated Financial Statements - Continued

The unrealized losses on the Company’s available-for-sale securities were primarily a result of unfavorable changes in interest rates subsequent to the initial purchase of these securities. As of April 30, 2013, the Company owned four securities that were in an unrealized loss position. The Company does not intend nor expect to need to sell these securities before recovering the associated unrealized losses. It expects to recover the full carrying value of these securities. As a result, no portion of the unrealized losses at April 30, 2013 is deemed to be other-than-temporary and the unrealized losses are not deemed to be credit losses. No available-for-sale securities have been in an unrealized loss position for 12 months or more. When evaluating the investments for other-than-temporary impairment, the Company reviews factors such as the length of time and extent to which fair value has been below cost basis, the financial condition of the issuer and any changes thereto, and the Company’s intent to sell, or whether it is more likely than not it will be required to sell, the investment before recovery of the investment’s amortized cost basis. During the three months ended April 30, 2013, the Company did not recognize any impairment charges.

4.                       Fair Value

The Company records cash equivalents and short-term investments at fair value.

Fair value is an exit price, representing the amount that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. Fair value measurements are required to be disclosed by level within the following fair value hierarchy:

Level 1 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2 — Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.

Level 3 — Inputs lack observable market data to corroborate management’s estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. As of January 31 and April 30, 2013 the Company did not hold any Level 3 assets.

When determining fair value, whenever possible the Company uses observable market data, and relies on unobservable inputs only when observable market data is not available.

The fair value of these financial assets and liabilities was determined using the following inputs at January 31 and April 30, 2013:

The Company’s money market funds are classified as Level 1 within the fair value hierarchy because they are valued primarily using quoted market prices. The Company’s other cash equivalents and short-term investments are classified as Level 2 within the fair value hierarchy because they are valued using professional pricing sources for identical or comparable instruments, rather than direct observations of quoted prices in active markets.

Legal Proceedings

Pandora has been in the past, and continues to be, a party to privacy and patent infringement litigation which has consumed, and may continue to consume, financial and managerial resources. The Company is also from time to time subject to various other legal proceedings and claims arising in the ordinary course of its business. The Company records a liability when it believes that it is both probable that a loss has been incurred and the amount can be reasonably estimated. Company management periodically evaluates developments that could affect the amount, if any, of liability that it has previously accrued and makes adjustments as appropriate. Determining both the likelihood and the estimated amount of a loss requires significant judgment, and management’s judgment may be incorrect. The Company does not believe the ultimate resolution of any pending legal matters is likely to have a material adverse effect on its business, financial position, results of operations or cash flows.

In June 2011, a putative class action lawsuit was filed against Pandora in the United States District Court for the Northern District of California alleging that it unlawfully accessed and transmitted personally identifiable information of the plaintiffs in connection with their use of the Company’s Android mobile application. In addition to civil liability, the amended complaint includes allegations of violations of statutes under which criminal penalties could be imposed if the Company were found liable. Pandora’s motion to dismiss the first amended complaint was granted on March 26, 2013. The court allowed the plaintiff to amend his complaint.  The amended complaint, filed May 9, 2013, contains allegations similar to those contained in the previous complaint.

In September 2011, a putative class action lawsuit was filed against Pandora in the United States District Court for the Northern District of California alleging that it violated Michigan’s video rental privacy law and consumer protection statute by allowing Pandora listeners’ listening history to be visible to the public. Pandora’s motion to dismiss the complaint was granted on September 28, 2012, judgment was entered on November 14, 2012 and the plaintiff filed a notice of appeal on December 14, 2012.

In April 2011, Augme Technologies, Inc. filed a complaint in the United States District Court for the District of Delaware against Pandora alleging patent infringement. The complaint sought injunctive relief and monetary damages. The parties negotiated a full and final settlement and the case was dismissed on March 15, 2013.

On September 10, 2012, B.E. Technology, LLC filed suit against Pandora in the United States District Court for the Western District of Tennessee alleging that Pandora infringes a B.E. Technology patent and seeking injunctive relief and monetary damages. Pandora filed its answer on December 31, 2012. The court has stayed the action pending its decision on the Company’s pending motion to transfer the action to the United States District Court for the Northern District of California.

On November 16, 2012, 1st Technology, LLC filed suit against Pandora in the United States District Court for the Northern District of Illinois alleging that Pandora infringes three 1st Technology patents and seeking injunctive relief and monetary damages.  The court stayed the action pending resolution of Pandora’s motion to transfer the action to the Northern District of California.

On January 15, 2012, Unified Messaging Solutions, LLC filed suit against Pandora in the U.S. District Court for the District of Delaware alleging that Pandora infringes four UMS patents and seeking injunctive relief and monetary damages.  Pandora filed its answer and counterclaims on March 29, 2013.  On April 11, 2013 the case was ordered joined with numerous additional cases that are combined in a multidistrict litigation proceeding pending in the U.S. District Court for the Northern District of Illinois.

On February 26, 2013, Macrosolve, Inc. filed suit against Pandora in the U.S. District Court for the Eastern District of Texas alleging that Pandora infringes a Macrosolve, Inc. patent and seeks injunctive relief and monetary damages. Pandora’s answer and counterclaims were filed on April 22, 2013.

The Company currently believes that it has substantial and meritorious defenses to the claims in the lawsuits discussed above and intends to vigorously defend its position.

The outcome of any litigation is inherently uncertain. Based on the Company’s current knowledge it believes that the final outcome of the matters discussed above will not likely, individually or in the aggregate, have a material adverse effect on its business, financial position, results of operations or cash flows; however, in light of the uncertainties involved in such matters, there can be no assurance that the outcome of each case or the costs of litigation, regardless of outcome, will not have a material adverse effect on the Company’s business.

Indemnification Agreements, Guarantees and Contingencies

In the ordinary course of business, the Company is party to certain contractual agreements under which it may provide indemnifications of varying scope, terms and duration to customers, vendors, lessors, business partners, and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, services to be provided by the Company or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with directors and certain officers and employees that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees. Such indemnification provisions are accounted for in accordance with guarantor’s accounting and disclosure requirements for guarantees, including indirect guarantees of indebtedness of others. To date, the Company has not incurred, does not anticipate incurring and therefore has not accrued for, any costs related to such indemnification provisions.

While the outcome of these matters cannot be predicted with certainty, the Company does not believe that the outcome of any claims under indemnification arrangements will have a material adverse effect on the Company’s financial position, results of operations, or cash flows.

7.                       Income Taxes

The income tax provision increased by $19,000 for the three months ended April 30, 2013 compared to the prior year period as a result of changes in states tax rules and additional international tax expense. The effective tax rate for the three months ended April 30, 2013 was less than one percent based on the estimated tax loss for the fiscal year.

There were no material changes to the unrecognized tax benefits in the three months ended April 30, 2013 and the Company does not expect significant changes to unrecognized tax benefits through the end of the fiscal year. Because of the Company’s history of tax losses, all years remain open to tax audit.

8.                       Debt Instruments

On May 13, 2011, the Company entered into a $30 million credit facility with a syndicate of financial institutions. The amount of borrowings available under the credit facility at any time is based on the Company’s monthly accounts receivable balance at such time, and the amounts borrowed are collateralized by the Company’s personal property (including such accounts receivable but excluding intellectual property). Under the credit facility, the Company can request up to $5 million in letters of credit be issued by the financial institutions.

The credit facility contains customary events of default, conditions to borrowing and covenants, including restrictions on the Company’s ability to dispose of assets, make acquisitions, incur debt, incur liens and make distributions to stockholders. The credit facility also includes a financial covenant requiring the maintenance of minimum liquidity of at least $5 million. During the continuance of an event of a default, the lenders may accelerate amounts outstanding, terminate the credit facility and foreclose on all collateral.

As of April 30, 2013, the Company had $828,000 in letters of credit outstanding and had $29.17 million of available borrowing capacity under the credit facility. On December 30, 2011, the Company entered into a cash collateral agreement in connection with the issuance of letters of credit which were used to satisfy deposit requirements under facility leases. As of April 30, 2013, the $828,000 cash collateral was considered to be restricted cash. The amount is included in other assets on the Company’s balance sheet.

Total debt issuance costs associated with the credit facility were $1.0 million, which are being amortized as interest expense over the four-year term of the credit facility agreement. For the three months ended April 30, 2013, $0.1 million of debt issuance costs were amortized and included in interest expense.

9.                       Stock-based Compensation Plans and Awards

The Company’s 2011 Equity Incentive Plan (the “2011 Plan”) provides for the issuance of stock options, restricted stock units and other stock-based awards. Each fiscal year, (beginning with the fiscal year that commenced February 1, 2012 and ending with the fiscal year commencing February 1, 2021), the number of shares in the reserve under the 2011 Plan may be increased by the lesser of (x) 10,000,000 shares, (y) 4.0% of the outstanding shares of common stock on the last day of the prior fiscal year or (z) another amount determined by the Company’s board of directors. The share reserve for the fiscal year beginning February 1, 2013 was increased in fiscal 2013 by 3% of the outstanding shares of common stock as of January 31, 2013. The 2011 Plan is scheduled to terminate in 2021, unless the board of directors determines otherwise. The 2011 Plan is administered by the compensation committee of the board of directors of the Company.

Valuation of Awards

The per-share fair value of each stock option was determined on the date of grant using the Black-Scholes option pricing model using the following assumptions:

Stock Options

A summary of stock option activity for the three months ended April 30, 2013 is as follows:

(1)                  Amounts represent the difference between the exercise price and the fair value of common stock at period end for all in the money options outstanding based on the fair value per share of common stock.

Notes to Condensed Consolidated Financial Statements - Continued

Restricted Stock Units

The fair value of the restricted stock units (“RSUs”) is expensed ratably over the vesting period. RSUs vest annually on a cliff basis over the service period, generally four years.

During the three months ended April 30, 2013, the Company recorded stock-based compensation expense related to RSUs of approximately $5.8 million. As of April 30, 2013, total compensation cost not yet recognized of approximately $93.7 million related to non-vested RSUs, is expected to be recognized over a weighted average period of 3.31 years.

The following table summarizes the activities for our RSUs for the three months ended April 30, 2013:

Stock Option Awards with Both a Service Period and a Market Condition

On March 22, 2012, Mr. Joseph Kennedy, the Company’s Chief Executive Officer, was granted a non-statutory stock option to purchase 800,000 shares of common stock. This option grant to Mr. Kennedy was intended to be in lieu of an annual equity grant for fiscal 2014. This option includes both a service period and a market vesting condition. The stock option will vest if the 60-day trailing volume weighted average price of the Company’s common stock exceeds $21.00 per share, or if there is a sale of the Company for at least $21.00 per share, in each case prior to July 6, 2017. If the market condition is met, the performance option will vest ratably over four years, beginning on July 6, 2013, subject to severance and change of control acceleration. To the extent that the market condition is not met, the option will not vest and will be cancelled. The Company used a binomial model to value the option with a market condition. The Company used Monte Carlo simulation techniques that incorporate assumptions as provided by management for the term of option from grant date (in years), risk-free interest rate, stock price volatility and beginning stock price. The Company does not adjust compensation cost recognition for subsequent changes in the expected outcome of the market-vesting conditions.

The following assumptions were used to value the grant using the Monte-Carlo simulation option pricing model: 10-year term, risk-free interest rate of 2.33%, expected volatility of 70% and a beginning stock price of $10.63. The grant-date fair value for the option was $6.08 per share.

On March 7, 2013, the Company announced that it will begin a process to identify a successor to Mr. Kennedy who will continue in his current role until his successor is named.  As a result, the Company re-evaluated certain estimates and assumptions related to the stock-based compensation expense associated with his awards and reduced current period stock-based compensation expense by $1.4 million related to the award with both a service period and a market condition and $0.3 million related to awards without a market condition.

Stock-based Compensation Expenses

The weighted-average fair value of stock option grants was $6.02 and $6.31 for the three months ended April 30, 2012 and 2013, respectively. As of April 30, 2013, total compensation cost related to stock options granted, but not yet recognized, was approximately $29.7 million which the Company expects to recognize over a weighted-average period of approximately 2.4 years.

The total grant date fair value of stock options vested during the three months ended April 30, 2012 and 2013 was $3.4 million and $2.2 million, respectively.  The aggregate intrinsic value of all options and exercised during the three months ended April 30, 2012 and 2013 was $32.4 million and $17.7 million, respectively.

Stock-based compensation expenses related to all employee and non-employee stock-based awards was as follows (in thousands):

10.                Net Loss Per Share

Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period.

Diluted net loss per share is computed by giving effect to all potential shares of common stock, including stock options and restricted stock units to the extent dilutive. Basic and diluted net loss per share was the same for the three months ended April 30, 2012 and 2013 as the inclusion of all potential common shares outstanding would have been anti-dilutive.

The following table sets forth the computation of historical basic and diluted net loss per share (in thousands except per share amounts):

The following potential common shares outstanding were excluded from the computation of diluted net loss per share because including them would have been anti-dilutive (in thousands):

Overview

Pandora is the leader in internet radio in the United States, offering a personalized experience for each of our listeners. We have pioneered a new form of radio—one that uses intrinsic qualities of music to initially create stations and then adapts playlists in real-time based on the individual feedback of each listener. As of April 30, 2013, we had approximately 200 million registered users, which we define as the total number of accounts that have been created for our service at period end. As of April 30, 2013 more than 150 million registered users have accessed Pandora through smartphones and tablets. For the three months ended April 30, 2013, we streamed 4.18 billion hours of radio and as of April 30, 2013, we had 70.1 million active users during the prior 30 day period. According to a December 2012 report by Triton, we have more than a 70% share of internet radio among the top 20 stations and networks in the United States. Since we launched our free, advertising-supported radio service in 2005 our listeners have created over 4.6 billion stations.

Since we started the Music Genome Project in 2000, we have continuously built our song catalog, refined the genotyping model and developed proprietary algorithms for building personalized playlists for our listeners based both on our analysis and feedback data from our listeners.

Our comedy service leverages similar technology to the technology underlying the Music Genome Project, allowing a listener to choose a favorite comedian or a genre as a seed to start a station and then give feedback to personalize that station.

One key element of our strategy is to make the Pandora service available everywhere that there is internet connectivity. To this end, we make the Pandora service available through a variety of distribution channels. In addition to streaming our service to traditional computers, we have developed Pandora mobile device applications or “apps” for smartphones such as Android, Blackberry and the iPhone, and for tablets including the iPad, Android tablets, and Amazon Kindle Fire tablets. We distribute those mobile apps free to listeners via app stores. Pandora is now available on more than 1,000 integrations, including automobiles, automotive aftermarket devices and consumer electronic devices. In the consumer electronics space, more than 760 consumer electronics devices from third-party distribution partners such as Samsung, Roku and DirecTV make Pandora available in the home. Many automotive partners, including Alpine Electronics, Audiovox, Clarion, Dual Electronics, JVC, Kenwood, Pioneer and Sony, incorporate our application into aftermarket radios. We have also developed relationships with major automobile manufacturers; vehicle models have been made available by Acura, BMW, Buick, Cadillac, Chevrolet, Ford, GMC, Honda, Hyundai, Lexus, Lincoln, Mazda, Mercedes-Benz, MINI, Nissan, Scion, Suzuki and Toyota. Additionally, Dodge, Infiniti, Jeep, Kia and Ram have publicly announced their plans to offer Pandora integration on future vehicles. Holden Ltd., a subsidiary of General Motors, has also launched the first in-car system in Australia to offer full compatibility with Pandora. Under the arrangements, we receive no financial compensation and recognize no revenue from these automotive distribution partners.

In June 2012, we entered into or activated agreements which allow Pandora to launch in New Zealand, Australia and the territories associated with the two countries. The arrangements with PPNZ Music Licensing Limited, which represents recording artists and record companies, and APRA/AMCOS, which represents songwriters, composers and publishers, have not had a material effect on our results of operations to date.

Business Model

We derive the substantial majority of our revenue from the sale of display, audio and video advertising for delivery across our traditional computer-based, mobile and other connected device platforms. We also offer a paid subscription service to listeners, which we call Pandora One. While historically our revenue growth was principally attributable to selling display advertising through our traditional computer-based platform, we now generate a majority of our revenue from mobile and other connected devices and our advertising includes a mix of audio, display and video. This expansion of our services also presents an opportunity for us to reach our audience anytime, anywhere they enjoy music, and therefore offer additional distribution channels to current and potential advertisers for delivery of their advertising messages.

Growth in our active users and distribution platforms has fueled a corresponding growth in listener hours. Our total number of listener hours is a key driver for both revenue generation opportunities and content acquisition costs, which are the largest component of our operating expenses:

·                  Revenue.  Listener hours define the number of opportunities we have to sell advertisements, which we refer to as inventory. Our ability to attract advertisers depends in large part on our ability to offer sufficient inventory within desired demographics. In turn, our ability to generate revenue depends on the extent to which we are able to sell the inventory we have.

·                  Cost of Revenue—Content Acquisition Costs.  The number of sound recordings we transmit to users of the Pandora service, as generally reflected by listener hours, drives substantially all of our content acquisition costs, although certain of our licensing agreements require us to pay fees for public performances based on a percentage of revenue.

We pay royalties to the copyright owners (or their agents) of each sound recording that we stream and to the copyright owner (or their agents) of the musical work that underlies that sound recording, subject to certain exclusions. We record these royalties as content acquisition costs. Under U.S. law, we are granted the right to stream any lawfully released sound recordings, subject to compliance with certain statutory and regulatory requirements. Royalties for sound recordings are negotiated with and paid to record labels or to SoundExchange, a performance rights organization (“PRO”) authorized to collect royalties on behalf of all sound recording copyright owners. Royalties for musical works are negotiated with and paid to publishing companies such as Sony ATV and Entertainment World Inc. or EMI; or PROs such as the American Society of Composers, Authors and Publishers, or ASCAP; Broadcast Music, Inc., or BMI; and SESAC Inc. or SESAC. Royalties are calculated based on sound recordings streamed, revenue earned or other usage measures. If we cannot agree on royalty rates, the dispute will be resolved by the Copyright Royalty Board, or CRB, in the case of SoundExchange, and by the rate court in the U.S. District Court for the Southern District of New York in the case of ASCAP and BMI. In November 2012, we filed a petition in rate court to request a determination of reasonable fees and terms with ASCAP. In May 2011, we started streaming spoken word comedy content, for which the underlying literary works are not currently entitled to eligibility for licensing by any PRO for the United States. Rather, pursuant to industry-wide custom and practice, this content is performed absent a specific license from any such performing rights organization. However, we pay royalties to SoundExchange at federally negotiated rates for the right to stream this spoken word comedy content.

Given the royalty structures in effect with respect to the public performance of sound recordings in the United States, our content acquisition costs increase with each additional listener hour, regardless of whether we are able to generate more revenue. As such, our ability to achieve and sustain profitability and operating leverage depends on our ability to increase our revenue per hour of streaming through increased advertising sales across all of our delivery platforms.

As our mobile listenership increases, we face new challenges in optimizing our advertising products for delivery on mobile and other connected device platforms and monetizing inventory generated by listeners using these platforms. The mobile digital advertising market is at an early stage of development, with lower overall spending levels than traditional online advertising markets, and faces technical challenges due to fragmented platforms and lack of standard audience measurement protocols.

In addition, our strategy includes increasing the number of ad campaigns for traditional computer, mobile and other connected device platforms sold to local advertisers, placing us in more direct competition with broadcast radio for advertiser spending, especially for audio advertisements. By contrast, historically our display advertisers have been predominantly national brands. To successfully monetize our growing listener hours, we may have to convince a substantial base of local advertisers of the benefits of advertising on the Pandora service including demonstrating the effectiveness and relevance of our advertising products, and in particular, audio advertising products, across the range of our delivery platforms.

Starting in March 2013, we instituted a 40 hour per month listening limit for our advertising supported service on certain mobile and other connected devices. Listeners who reach this limit may continue to use our ad supported service on these devices by paying $0.99 for the remainder of the month, may listen to our ad supported service on their desktop or laptop computers, or may purchase annual or monthly Pandora One subscriptions for $36 per year or approximately $4 per month, respectively.

Our total revenue has grown from $80.8 million in the three months ended April 30, 2012 to $125.5 million in the three months ended April 30, 2013. At the same time, our total costs and expenses have grown from $100.9 million in the three months ended April 30, 2012 to $154.0 million in the three months ended April 30, 2013, principally as a result of the growth in content acquisition costs. As the volume of music we stream to listeners in the United States increases, our content acquisition costs will also increase, regardless of whether we are able to generate more revenue. In addition, we expect to invest heavily in our operations to support anticipated future growth. One of our key objectives is furthering our market leadership in internet radio, which we believe will strengthen our brand and help us to convince advertisers to allocate spending towards our ad products. As such, a central focus is adding, retaining and engaging listeners to build market share and grow our listener hours. For the foreseeable future, we expect that there will be periods during which our ability to monetize listener hours will lag the growth of listener hours. As our business matures, we expect that the growth rate in our listener hours will decline relative to our increased ability to monetize listener hours. However, we expect to incur annual losses on a U.S. GAAP basis in the near term.

Key Metrics:

The tables below set forth our listener hours for the three months ended April 30, 2012 and 2013 and our active users as of January 31, 2013 and April 30, 2013, along with our total, traditional computer and mobile and other connected devices ad RPMs and LPMs for the three months ended April 30, 2012 and 2013.

Active Users.  Active users are defined as the number of distinct registered users that have requested audio from our servers within the trailing 30 days to the end of the final calendar month of the period. The number of active users may overstate the number of unique individuals who actively use our service within a month as one individual may register for, and use, multiple accounts. We track the number of active users as an additional indicator of the breadth of audience we are reaching at a given time, which is particularly important to potential advertisers.

Listener Hours.  We track listener hours because it is a key indicator of the growth of our business.  We calculate listener hours based on the total bytes served for each track that is requested and served from our servers, as measured by our internal analytics systems, whether or not a listener listens to the entire track. We believe this server-based approach is the best methodology to forecast advertising inventory given that advertisements are frequently served in between tracks and are often served upon triggers such as a listener clicking thumbs-down or choosing to skip a track. To the extent that third-party measurements of listener hours are not calculated using a similar server-based approach, the third-party measurements may differ from our measurements.

Ad RPMs.  We track advertising revenue per thousand listener hours for our free, advertising supported service (“ad RPMs”) because it is a key indicator of our ability to monetize advertising inventory created by our listener hours. We focus on total ad RPMs across all of our delivery platforms. RPMs compare advertising revenue generated in a given period to advertising supported listener hours in the period and we believe such total ad RPMs to be the central top-line indicator for evaluating the results of our monetization efforts. We calculate total ad RPMs by dividing advertising revenue we generate by the number of thousands of listener hours of our advertising-based service.

Total RPMs. We also provide estimates of disaggregated total and ad RPMs for our traditional computer platform as well as our mobile and other connected devices platforms, which we calculate by dividing the estimated advertising revenue generated through the respective platforms by the number of thousands of listener hours of our advertising-based service delivered through such platforms. While we believe that such disaggregated RPMs provide directional insight for evaluating our efforts to monetize our service by platform, we do not validate disaggregated RPMs to the level of financial statement reporting. Such metrics should be seen as indicative only and as management’s best estimate. We continue to refine our systems and methodologies used to categorize RPMs across our delivery platforms. Period-to-period results should not be regarded as precise nor can they be relied upon as indicative of results for future periods. In addition, as our business matures and in response to technological evolutions, we anticipate that the relevant indicators we monitor for evaluating our business may change.

LPMs.  We track licensing costs per thousand listener hours (“LPMs”) and analyze them in combination with our analysis of RPMs as they provide a key indicator of our profitability. LPMs are relatively fixed licensing costs with scheduled annual rate increases which drive period over period changes in LPMs.  The margin on our business improves with growth in ad RPMs and subscription RPMs.

Table of Contents

Total ad RPMs. Three months ended April 30, 2012 and 2013.  Total ad RPMs increased compared to the respective prior year period due to advertising sales growth outpacing the growth in advertising listener hours in part due to the effect of the listening limit on mobile and other connected devices.

Traditional computer ad RPMs. Three months ended April 30, 2012 and 2013.  Traditional computer ad RPMs increased compared to the respective prior year period, primarily due to traditional computer revenue growing at a faster pace than listening hours on that platform primarily due to an increase in the number of ads sold.

Mobile and other connected device ad RPMs. Three months ended April 30, 2012 and 2013.  Mobile and other connected device ad RPMs increased compared to the respective prior year periods primarily due to mobile and connected device revenue growing at a faster pace than listening hours due in part to the effect of the listening limit on certain mobile and other connected devices.

Specific to the revenue component of the RPM ratio, total advertising revenue increased by approximately 49% during the three months ended April 30, 2013 compared to the prior year period, with advertising revenue on mobile and other connected devices increasing approximately 83% and advertising revenue on traditional computers increasing by approximately 8%.

Total RPMs for the three months ended April 30, 2012 and 2013 were $26.09 and $30.01, respectively. Within this, mobile and other connected device total RPMs for the three months ended April 30, 2012 and 2013, were $18.86 and $25.31 respectively. Traditional computer RPMs for the three months ended April 30, 2012 and 2013 were $45.54 and $48.04, respectively. These changes were driven by the same factors mentioned above within the discussion of ad RPMs.

Basis of Presentation

Revenue

Advertising Revenue.  We generate advertising revenue primarily from display, audio and video advertising, which is typically sold on a cost-per-thousand impressions, or CPM, basis. Advertising campaigns typically range from 1 to 12 months, and advertisers generally pay us based on a minimum number of delivered impressions or the satisfaction of other criteria, such as click-throughs. We may earn referral revenue when, for example, a listener clicks on an advertisement and signs up for membership with an advertiser. We also have arrangements with advertising agencies and brokers pursuant to which we provide the ability to sell advertising inventory on our service directly to advertisers. We report revenue under these arrangements net of amounts due to agencies and brokers. For the three months ended April 30, 2012 and 2013, advertising revenue accounted for 87% and 84% of our total revenue, respectively, and we expect that advertising will comprise a substantial majority of revenue for the foreseeable future. Advertising revenue decreased as a percentage of total revenue due to higher subscription sales partially driven by the implementation of the mobile listening limit.

Subscription Services and Other Revenue.  Subscription revenue is generated through the sale of a premium version of the Pandora service which currently includes advertisement-free access and higher audio quality on the devices that support it. Subscription revenue derived from direct sales to listeners is recognized on a straight-line basis over the duration of the subscription period. Subscription revenue derived from sales through some mobile operating systems may be subject to refund or cancellation terms which may affect the timing or amount of the subscription revenue recognition. When refund rights exist, we recognize revenue when services have been provided and the rights lapse or when we have developed sufficient transaction history to estimate a reserve. As of April 30, 2013, we had deferred all revenue subject to refund rights totaling approximately $8.1 million, as we do not currently have sufficient history to estimate a reserve. For the three months ended April 30, 2012 and 2013, subscription services and other revenue accounted for 13% and 16% of our total revenue, respectively. Subscription services revenue increased as a percentage of total revenue due to higher subscription sales partially driven by the implementation of the mobile listening limit.

Deferred Revenue.  Our deferred revenue consists principally of both prepaid but unrecognized subscription revenue and advertising fees received or billed in advance of the delivery or completion of the delivery of services. Deferred revenue is recognized as revenue when the services are provided and all other revenue recognition criteria have been met.

Costs and Expenses

Costs and expenses consist of cost of revenue — content acquisition costs, cost of revenue - other, product development, marketing and sales and general and administrative expenses. Cost of revenue - content acquisition costs are the most significant component of our costs and expenses followed by employee-related costs, which includes stock-based compensation expenses. We

25

Table of Contents

expect to continue to hire additional employees in order to support our anticipated growth and our product development initiatives. In any particular period, the timing of additional hires could materially affect our operating expenses, both in absolute dollars and as a percentage of revenue. We anticipate that our costs and expenses will increase in the future.

Cost of revenue—Content Acquisition Costs.  Content acquisition costs principally consist of royalties paid for streaming music or other content to our listeners. Royalties are calculated using negotiated rates documented in master royalty agreements and are based on both percentage of revenue and listening metrics. For example in the three months ended April 30, 2012 and 2013, under some royalty arrangements we paid a fee per track, while in other cases we paid royalties based on a percentage of our revenue. In still other cases we pay royalties based on a combination of these metrics.

We periodically test our royalty calculation methods to ensure we are accurately reporting and paying royalties. The performance rights organizations have the right to audit our playlist and payment records, and any such audit could result in disputes over whether we have paid the proper royalties. If such a dispute were to occur, we could be required to pay additional royalties and the amounts involved could be material.

For royalty arrangements under negotiation, we accrue for estimated royalties based on the available facts and circumstances and adjust these estimates as more information becomes available. The results of any finalized negotiation may be materially different from our estimates.

In July 2009 we, together with other webcasters, negotiated new royalty rates on performances with SoundExchange for calendar years 2006 to 2015. The agreement reduced rates originally established by the Copyright Royalty Board for calendar years 2006 to 2010 and established new rates for calendar years 2011 to 2015.

Cost of Revenue—Other.  Cost of revenue consists of hosting costs, infrastructure and the employee and employee-related costs associated with supporting those functions. Hosting costs consist of content streaming, maintaining our internet radio service and creating and serving advertisements through third-party ad servers. Infrastructure costs consist of equipment, software, facilities and depreciation. We make payments to third-party ad servers for the period the advertising impressions or click-through actions are delivered or occur, and accordingly, we record this as a cost of revenue in the related period.

Product Development.  Product development expenses consist of employee compensation, information technology, consulting, facilities-related expenses and costs associated with supporting consumer connected-device manufacturers in implementing our service in their products. We incur product development expenses primarily for improvements to our website and the Pandora app, development of new advertising products and development and enhancement of our personalized station(s) generating system. We have generally expensed product development as incurred. Certain website development and internal use software development costs may be capitalized when specific criteria are met. In such cases, the capitalized amounts are amortized over the useful life of the related application once the application is placed in service. We intend to continue making significant investments in developing new products and enhancing the functionality of our existing products.

Marketing and Sales.  Marketing and sales expenses consist of employee and employee-related costs including salaries, commissions and benefits related to employees in sales, marketing and advertising departments. In addition, marketing and sales expenses include external sales and marketing expenses such as third-party marketing, branding, advertising, and public relations expenses, transactional subscription processing fees on mobile platforms, and infrastructure costs such as facility and other supporting overhead costs. We expect marketing and sales expenses to increase as we hire additional personnel to build out our sales force and ad operations team and expand our business development team to establish relationships with manufacturers of an increasing number of connected devices.

General and Administrative.  General and administrative expenses include employee and employee-related costs consisting of salaries and benefits for finance, accounting, legal, internal information technology and other administrative personnel. In addition, general and administrative expenses include professional services costs for outside legal and accounting services, and infrastructure costs for facility, supporting overhead costs and merchant and other transaction costs, such as credit card fees. We expect to incur significant additional expenses in future periods as we continue to invest in corporate infrastructure, including adding personnel and systems to our finance and administrative functions.

Provision for Income Taxes.  We have historically been subject to income taxes only in the United States. As we expand our operations outside the United States, we have become subject to taxation based on the foreign statutory rates and our effective tax rate could fluctuate accordingly.

Table of Contents

Income taxes are computed using the asset and liability method, under which deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted statutory income tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce net deferred tax assets to the amount expected to be realized.

Comparison of the Three Months Ended April 30, 2012 and 2013

Revenue

Three months ended 2012 compared to 2013. Advertising revenue increased $34.5 million or approximately 49% in the three months ended April 30, 2013, primarily due to an approximate 76% increase in the number of ads delivered, partially offset by a decrease in the average price per ad of approximately 15% due to fluctuations in the sales distribution mix amongst direct sales, third-party network sales, and other channels and the platform mix between traditional computer and mobile and other connected devices.  The increase in the number of ads delivered was primarily due to an increase in total advertising listener hours of approximately 32%

which increased the volume of advertising inventory as well as an increase in our sales force by approximately 73% year-over-year to sell such advertising inventory.  Subscription revenue increased $10.2 million due to an increase in the number of subscribers, partially driven by the implementation of the mobile listening limit.

Total ad RPMs three months ended 2012 compared to 2013.  Total ad RPMs increased compared to the respective prior year period due to advertising sales growth outpacing the growth in advertising listener hours in part due to the effect of the listening limit on certain mobile and other connected devices.

Costs and Expenses

Cost of Revenue - Content acquisition costs

The following table presents our estimated content acquisition costs for our advertising-based service attributable to our traditional computer platform and our mobile and other connected devices platforms as percentages of the estimated advertising revenue attributable to such platforms.

The majority of our royalties are payable based on a fee per track, while in other cases our royalties are payable based on a percentage of our revenue or a combination of per track and revenue metrics. We estimate our advertising-based content acquisition costs attributable to specific platforms by allocating costs from royalties payable based on a fee per track to the platform for which the track is served and by allocating costs from royalties based on a percentage of our revenue in accordance with the overall percentage of our revenue estimated to be attributable to such platforms. While we believe that comparing disaggregated content acquisition costs and revenues across our delivery platforms may provide directional insight for evaluating our efforts to monetize the rapid adoption of our service on mobile and other connected devices, we do not validate such disaggregated metrics to the level of financial statement reporting. We continue to refine our systems and methodologies used to categorize such metrics across our delivery platforms and the period-to-period comparisons of results are not necessarily indicative of results for future periods.

Three months ended 2012 compared to 2013.  Content acquisition costs increased $27.0 million due to increased royalty payments driven by increased listener hours and higher royalty rates due to scheduled rate increases, and higher revenue. Content acquisition costs as a percentage of total revenue decreased from 69% to 66%, primarily due to an increase in advertising sales and the effect of the mobile listening limit, partially offset by scheduled rate increases. Estimated content acquisition costs as a percentage of the revenue attributable to our traditional computer platform remained flat at 39%, as rate increases were offset by growth in advertising sales on that platform. Estimated content acquisition costs as a percentage of the revenue attributable to our mobile and other connected devices platforms decreased from 94% to 78%, primarily due to an increase in advertising sales on those platforms and the effect of the mobile listening limit, partially offset by scheduled rate increases.
