Notes to Condensed Consolidated and Combined Financial Statements
(Unaudited)
1. |
Organization and Description of Business |
Atara Biotherapeutics, Inc. (“Atara”, “we” or “our”) was incorporated in August 2012 in Delaware. We are a clinical-stage biopharmaceutical company focused on developing meaningful therapies for patients with unmet medical needs in diseases that have seen limited therapeutic innovation, with an initial focus on muscle wasting conditions, oncology and viral-associated diseases. Our product candidate portfolio was acquired through licensing arrangements with Amgen Inc. (“Amgen”) and Memorial Sloan Kettering Cancer Center (“MSK”) in exchange for convertible preferred stock, common stock, milestone payments and commitments for future royalties. See Note 4 for further information.
In February 2015, we completed a follow-on offering of 4,147,358 shares of common stock at an offering price to the public of $18.00 per share. We received net proceeds of approximately $69.5 million, after deducting underwriting discounts and commissions and offering expenses.
In July 2015, we completed a follow-on offering of 3,980,768 shares of common stock at an offering price to the public of $52.00 per share. We received net proceeds of approximately $193.9 million, after deducting underwriting discounts and commissions and offering expenses.

Summary of Significant Accounting Policies |
Basis of Presentation and Recapitalization
The accompanying interim condensed consolidated and combined financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”). The accounting policies followed in the preparation of the interim condensed consolidated and combined financial statements are consistent in all material respects with those presented in Note 2 to the consolidated and combined financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.
Atara was originally formed as a management company with the sole purpose of providing management, financial and administrative services for Nina Biotherapeutics, Inc. (“Nina”), Santa Maria Biotherapeutics, Inc. (“Santa Maria”) and Pinta Biotherapeutics, Inc. (“Pinta”). Prior to March 31, 2014, the accompanying financial statements include the operations of Atara, Nina, Pinta and Santa Maria on a combined basis as the four individual companies were under common ownership and common management since inception. All intercompany transactions have been eliminated.
On March 31, 2014, our board of directors approved and we implemented a recapitalization (the “Recapitalization”) in which (a) all the outstanding shares of common stock of Atara were cancelled and forfeited by existing stockholders and (b) the stockholders of Nina, Pinta and Santa Maria exchanged their existing common and convertible preferred stock for newly-issued shares of Atara, with the same rights and privileges as the outstanding capital stock of Nina, Pinta and Santa Maria. The shares were exchanged on a collective nine-for-one basis. The Recapitalization lacked economic substance as the newly-issued shares have the same rights and privileges as the previously outstanding capital stock of Nina, Pinta and Santa Maria and there was no change in ownership percentages of the individual stockholders. As a result of the Recapitalization, Nina, Pinta and Santa Maria became wholly owned subsidiaries of Atara effective March 31, 2014. The Recapitalization is considered a tax-free exchange for U.S. federal income tax purposes.
Because the four individual companies were under common ownership and the Recapitalization lacked economic substance, we accounted for the Recapitalization as a combination of businesses under common control. The assets and liabilities of Nina, Pinta and Santa Maria were recorded by Atara at their historical carrying amounts on March 31, 2014 and beginning March 31, 2014, the financial statements of the Company are presented on a consolidated basis.
Liquidity
We have incurred significant operating losses since inception and have relied on public and private equity financings to fund our operations. At September 30, 2015, we had an accumulated deficit of $76.9 million. As we continue to incur losses, our transition to profitability will depend on the successful development, approval and commercialization of product candidates and on the achievement of sufficient revenues to support our cost structure. We may never achieve profitability, and unless and until we do, we will need to continue to raise additional capital. Management expects that existing cash and cash equivalents as of September 30, 2015 will be sufficient to fund our current operating plan for at least the next twelve months.

Net Loss per Common Share
Basic and diluted net loss per common share is presented, giving effect to the Recapitalization, including cancellation of existing Atara common stock and a nine-for-one share exchange. Basic net loss per common share is calculated by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, without consideration of common stock equivalents. Diluted net loss per common share is computed by dividing the net loss by the weighted-average number of shares of common stock and common share equivalents outstanding for the period. Common share equivalents are only included in the calculation of diluted net loss per common share when their effect is dilutive. Our restricted stock awards are considered to be participating securities as they are entitled to participate in undistributed earnings with shares of common stock. Due to net losses, there is no impact on the net loss per common share calculation in applying the two-class method since the participating securities have no legal requirement to share in any losses.
Potentially dilutive securities, which include convertible preferred stock, unvested restricted common stock awards, unvested restricted stock units and vested and unvested options have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per common share and be antidilutive. Therefore, the denominator used to calculate both basic and diluted net loss per common share is the same in all periods presented.
The following common stock equivalents have been excluded from the computations of diluted net loss per common share as the effect of including such securities would be antidilutive:

In addition, options to purchase 380,083 and 240,014 shares have been excluded from the above table for the three and nine months ended September 30, 2015, respectively, as the exercise prices of the underlying options were greater than the average fair value of our common stock for the periods presented.
Recent Accounting Pronouncements
In April 2015, the FASB issued ASU No. 2015-05, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement”, that provides guidance to customers about whether a cloud computing arrangement includes a software license. If such an arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the arrangement does not include a software license, the customer should account for it as a service contract. This ASU will be effective for annual periods beginning after December 15, 2015, and early application is permitted. Entities may apply the new guidance either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. We adopted this standard prospectively on July 1, 2015. Adoption of this standard did not have a material impact on our financial statements.
In August 2014, the FASB issued a new accounting standard to provide guidance on the presentation of management’s plans, when conditions or events raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. The new standard is effective for fiscal years ending after December 15, 2016. The adoption of this standard is not expected to have a material impact on our financial statements.

In May 2014, the FASB issued a new accounting standard, Revenue from Contracts with Customers, which supersedes the revenue recognition requirements in the current standard, Revenue Recognition. This new standard affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets. The new standard is effective for fiscal years beginning after December 15, 2017. We will evaluate the application of this standard on our financial statements and disclosures when we enter into any contracts with customers.

Fair Value of Financial Instruments |
Our financial assets and liabilities carried at fair value are primarily comprised of investments in money market funds, corporate bonds, U.S. government securities, asset-backed securities and commercial paper. The fair value accounting guidance requires that assets and liabilities be carried at fair value and classified in one of the following three categories:
Level 1: |
|
Quoted prices in active markets for identical assets or liabilities that we have the ability to access |
Level 2: |
|
Observable market based inputs or unobservable inputs that are corroborated by market data such as quoted prices, interest rates and yield curves |
Level 3: |
|
Inputs that are unobservable data points that are not corroborated by market data |
We review the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels of certain securities within the fair value hierarchy. We recognize transfers into and out of levels within the fair value hierarchy in the period in which the actual event or change in circumstances that caused the transfer occurs. There were no transfers between Level 1, Level 2, and Level 3 for all periods presented.
The following table represents the fair value hierarchy for our financial assets and financial liabilities measured at fair value on a recurring basis:

Financial assets and liabilities are considered Level 2 when their fair values are determined using inputs that are observable in the market or can be derived principally from or corroborated by observable market data such as pricing for similar securities, recently executed transactions, cash flow models with yield curves, and benchmark securities. In addition, Level 2 financial instruments are valued using comparisons to like-kind financial instruments and models that use readily observable market data as their basis. Corporate bonds, U.S. government securities, asset-backed securities and commercial paper are valued primarily using market prices of comparable securities, bid/ask quotes, interest rate yields and prepayment spreads and are included in Level 2.
Financial assets and liabilities are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies, or similar techniques, and at least one significant model assumption or input is unobservable. We have no Level 3 financial assets and liabilities.
Short-term available-for-sale investments are carried at fair value and are included in the tables above under short-term investments. The aggregate market value, cost basis, and gross unrealized gains and losses of short-term available-for-sale investments by major security type are as follows:

Amgen License Agreements - In September 2012, we entered into three license agreements with Amgen, one of our investors, for the development, manufacturing, use and distribution of products using certain proprietary compounds. Under the terms of these agreements, we paid $250,000 and issued 5,538,462 shares of Series A-1 convertible preferred stock (615,384 shares after giving effect to the Recapitalization) to Amgen. We are obligated to make additional payments to Amgen of up to $86.0 million upon the achievement of certain development and regulatory approval milestones, of which $1.0 million has been paid to date. Of these milestone payments, $14.0 million relate to milestones for clinical trials. The remaining $72.0 million relate to milestones for regulatory approvals in various territories and are anticipated to be made no earlier than 2018. Thereafter, we are obligated to make tiered payments based on achievement of commercial milestones based upon net sales levels. The maximum payments would be $206.0 million based on sales of over $1.0 billion for each of three products in a calendar year. We are also obligated to pay mid-single-digit percentage tiered royalties on future net sales of products which are developed and approved as defined by the agreements. Our royalty obligations as to a particular licensed product will be payable, on a country-by-country and product-by-product basis, until the later of (a) the date of expiration of the last to expire valid claim within the licensed patents that covers the manufacture, use or sale, offer to sell, or import of such licensed product by us or a sublicense in such country, (b) loss of regulatory exclusivity or (c) 10 years after the first commercial sale of the applicable licensed product in the applicable country. These agreements expire at the end of all royalty obligations to Amgen and, upon expiration, the licenses will be fully paid, royalty-free, irrevocable and non-exclusive. As of September 30, 2015 and December 31, 2014, there were no outstanding obligations due to Amgen.
At September 30, 2015, Amgen owns approximately 5.2% of our outstanding voting capital stock. Amgen does not have any rights to participate in our product candidates’ development and is not represented on our board of directors.
MSK Agreements – In September 2014, we entered into an exclusive option agreement with MSK under which we had the right to acquire the exclusive worldwide license rights to the three clinical stage T-cell therapies of MSK. The initial option period was for twelve months, with extensions available to extend the term up to 27 months at the option of Atara. Under the terms of the option agreement, we were obligated to use reasonable efforts to prepare a request to be submitted to the U.S. Food and Drug Administration (the “FDA”) regarding a meeting to discuss pivotal trials for one of the clinical stage T-cell therapies. In exchange for the exclusive option, we paid MSK $1.25 million in cash and issued 59,761 shares of our common stock to MSK. At the time of issuance, we estimated the fair value of the common stock issued to MSK to be $750,000. This total of $2.0 million was recorded as research and development expense in our condensed consolidated and combined statement of operations and comprehensive loss in the third quarter of 2014.
In June 2015, we exercised our option and entered into an exclusive license agreement with MSK. In connection with the execution of the License Agreement, Atara is obligated to make an upfront cash payment to MSK of $4.5 million and this amount has been recorded as research and development expense in our condensed consolidated and combined statement of operations and comprehensive loss in the second quarter of 2015. Atara is obligated to make additional payments of up to $33.0 million to MSK based on achievement of specified development, regulatory and sales-related milestones, as well as escalating mid single-digit royalties based on future sales of products resulting from the development of the licensed product candidates. In addition, under certain circumstances, we must make certain minimum annual royalty payments to MSK, which are creditable against earned royalties owed for the same annual period. We are also obligated to pay a low double-digit percentage of consideration we receive for sublicensing the licensed rights. The license agreement expires on a product-by-product and country-by-country basis on the later of: (i) expiration of the last licensed patent rights related to each licensed product, (ii) expiration of any market exclusivity period granted by law with respect to each licensed product, and (iii) a specified number of years after the first commercial sale of the licensed product in each country. Upon expiration of the license agreement, Atara will retain non-exclusive rights to the licensed products.
Patent Obligations – Under the terms of our license agreements with Amgen and MSK, we pay costs related to the preparation, filing, prosecution, defense and maintenance of the patents covered by the license agreements. During the three months ended September 30, 2015 and 2014, we incurred expenses of $412,389 and $447,518, respectively, related to the preparation, filing and maintenance of patents. During the nine months ended September 30, 2015 and 2014, patent costs were $1,251,824 and $842,228. These patent costs were recorded in the condensed consolidated and combined statement of operations and comprehensive loss as general and administrative expenses.

Operating Leases
In September 2015, we amended our lease agreement for office and laboratory facilities in Westlake Village, California to add additional office space and extend the term of the agreement to April 2019.
As of September 30, 2015, future minimum commitments for all operating leases are as follows:

Indemnification Agreements
In the normal course of business, we enter into contracts and agreements that contain a variety of representations and warranties and provide for indemnification for certain liabilities. The exposure under these agreements is unknown because it involves claims that may be made against us in the future but have not yet been made. To date, we have not paid any claims or been required to defend any action related to our indemnification obligations. However, we may record charges in the future as a result of these indemnification obligations. We also have indemnification obligations to our directors and executive officers for specified events or occurrences, subject to some limits, while they are serving at our request in such capacities. There have been no claims to date and we believe the fair value of these indemnification agreements is minimal. Accordingly, we have not recorded any liabilities for these agreements as of September 30, 2015 and December 31, 2014.

Stockholders’ Equity |
Restricted Common Stock
In August 2012, in connection with our formation, our CEO purchased 9,595,384 shares of restricted common stock at a nominal per share purchase price. The shares were issued subject to certain vesting conditions, restrictions on transfer and a Company right of repurchase of any unvested share at their original purchase price. These shares are placed in escrow until vested, and have rights to vote and participate in dividends and distributions. The combined grant date intrinsic value for this award was $1,704,094 and 7,996,153 of these shares had service and fundraising vesting conditions. Under the service vesting condition, shares vest monthly over 48 months, commencing from the first closing of Series A convertible preferred stock financing on October 22, 2012. 1,599,231 of these shares were subject to performance milestones and fundraising vesting conditions. The fundraising vesting conditions for all shares were satisfied as of December 31, 2013. All shares subject to service vesting conditions are subject to accelerated vesting in the event of certain change of control transactions.
In March 2013, an Atara employee purchased 2,423,074 shares of restricted common stock for $331,170. The shares were issued under our 2012 Equity Incentive Plan (as discussed below) and are subject to certain vesting conditions, restrictions on transfer and a Company right of repurchase of any unvested shares at their original purchase price. These shares are placed in escrow until vested, and have rights to vote and participate in dividends and distributions. Under these agreements, the shares vest as follows: 2,319,228 shares vest over four years, with one-quarter vesting after one year of service and the remainder vesting in equal installments over the subsequent thirty-six months, and 103,846 shares vest upon achievement of certain performance milestones. Vesting of all shares is subject to acceleration of vesting in the event of certain change of control transactions.
The amounts paid for both restricted stock purchases were initially recorded as other long-term liabilities. As shares vest, we reclassify liabilities to equity and report shares as outstanding in the condensed consolidated and combined financial statements. On March 31, 2014, the shares were exchanged for 1,335,384 shares of Atara common stock. At September 30, 2015, 1,030,336 shares had vested and are classified as equity. Restricted stock shares not vested at September 30, 2015 totaled 305,048 shares and are expected to be fully vested by December 31, 2016.
11
As both the Chief Executive Officer and the Atara employee were consultants of Nina, Pinta and Santa Maria through the Recapitalization date, we accounted for these awards as non-employee stock-based awards. Following the Recapitalization, these awards were accounted as employee awards based upon the fair market value of common stock on March 31, 2014. Stock-based compensation expense related to these awards is recorded using an accelerated graded vesting model and was $213,240 and $431,974 for the three months ended September 30, 2015 and 2014, respectively, and $802,360 and $4.3 million for the nine months ended September 30, 2015 and 2014, respectively. The unrecognized stock-based compensation expense related to this unvested restricted stock was $381,402 at September 30, 2015 and this expense is expected to be recognized over a weighted-average period of 0.55 years. The aggregate intrinsic value of unvested restricted stock is $9.5 million at September 30, 2015.
2014 Equity Incentive Plans
In March 2014, we adopted the 2014 Equity Incentive Plan (the “2014 plan”) as part of our Recapitalization. In connection with the Recapitalization, Atara assumed the plans of Nina, Pinta and Santa Maria and all outstanding restricted stock units (“RSUs”) and restricted stock awards granted under such plans. At the date of Recapitalization, RSUs and restricted stock awards issued by Nina, Pinta and Santa Maria to Atara employees became employee awards and the awards’ grant dates were established as the Recapitalization date. In May 2014, our board of directors amended and restated our 2014 plan and the amended plan became effective on October 15, 2014 upon the pricing of our initial public offering. The maximum number of shares of our common stock that may be issued pursuant to stock awards under the 2014 plan is 4,536,797 shares, including 1,294,041 shares that were previously available for issuance under the 2012 plans.
The number of shares of our common stock reserved for issuance pursuant to stock awards under our 2014 plan will automatically increase on January 1 of each year for a period of up to ten years, beginning on January 1, 2015 and ending on and including January 1, 2024, by 5% of the number of shares of our capital stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined by our board of directors. The number of shares of our common stock available for issuance under the 2014 plan is 1,819,006 at September 30, 2015.
Under the terms of the 2014 plan, we may grant options, restricted stock awards and RSUs to employees, directors, consultants and other service providers. RSUs typically require settlement by the earlier of seven years from the date of grant or the service termination (or, for RSUs granted prior to February 2014, two years following the service termination date). Stock options are granted at prices no less than 100% of the estimated fair value of the shares on the date of grant as determined by the board of directors, provided, however, that the exercise price of an option granted to a 10% shareholder cannot be less than 110% of the estimated fair value of the shares on the date of grant. Options granted to employees and non-employees generally vest over four years and expire in seven years.
Restricted Stock Units and Awards
The RSUs granted prior to our initial public offering had a time-based service condition and a liquidity-based performance condition, and vest when both conditions are met. We determined that the liquidity-based performance condition was not probable of occurring and recorded no stock-based compensation expense related to the RSUs prior to our initial public offering. Upon the closing of our initial public offering in October 2014, we recorded $3.8 million of stock-based compensation expense in our consolidated and combined statement of operations and comprehensive loss for the quarter ended December 31, 2014. The remaining unrecognized stock-based compensation expense relating to nonvested RSUs will be recognized as the RSUs vest over the remaining service periods through 2018. As of September 30, 2015, there was $2.4 million of unrecognized stock-based compensation expense related to RSUs that is expected to be recognized over a weighted average period of 1.19 years. The aggregate intrinsic value of the RSUs outstanding at September 30, 2015 was $15.8 million.

Under our RSU net settlement procedures, we withhold shares at settlement to cover the minimum payroll withholding obligations for employee income and other employment taxes. During 2015, we settled 400,346 RSUs, of which 287,881 RSUs were net settled by withholding 122,061 shares. The value of these withheld RSUs was $4.6 million, based on the closing price of our common stock on the settlement date. This amount was remitted to the appropriate taxing authorities and $4.6 million has been reflected as a financing activity in our consolidated and combined statement of cash flows. These withheld shares are no longer considered issued and outstanding, thereby reducing our shares outstanding used to calculated earnings per share, and these shares were returned to the shares reserved for issuance under our 2014 plan and are available for future issuance.

Aggregate intrinsic value represents the difference between the closing stock price of our common stock on September 30, 2015 and the exercise price of outstanding, in-the-money options. As of September 30, 2015, there was $20.7 million of unrecognized stock-based compensation expense related to stock options that is expected to be recognized over a weighted average period of 3.14 years.
The fair value of options issued during 2015 was estimated at the date of grant using the Black-Scholes valuation model with the following weighted-average assumptions:

Management’s Discussion and Analysis of Financial Condition and Results of Operations
You should read the following discussion and analysis of our financial condition and results of operations together with our audited consolidated and combined financial statements and related notes included in our 2014 Annual Report on Form 10-K. This discussion and other parts of this quarterly report contain forward-looking statements that involve risk and uncertainties, such as statements of our plans, objectives, expectations and intentions. As a result of many factors, including those factors set forth in the “Risk Factors” section of this quarterly report, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.
Overview
We are a clinical-stage biopharmaceutical company focused on developing innovative therapies for patients with debilitating diseases. We have two groups of product candidates: molecularly targeted biologics and allogeneic, or third-party derived, antigen-specific T-cells, a type of white blood cell. Our molecularly targeted product candidates are biologics that inhibit myostatin and activin, members of the Transforming Growth Factor-Beta, or TGF-ß, protein superfamily, which play roles in the growth and maintenance of muscle and many other body tissues. Our lead molecularly targeted product candidate, PINTA 745, is in a Phase 2 clinical trial for protein energy wasting, a condition affecting many end-stage renal disease patients. Our second molecularly targeted product candidate is STM 434. We commenced a Phase 1 clinical study of STM 434 for ovarian cancer and other solid tumors in 2014. We have five additional molecularly targeted product candidates that modulate the TGF-ß pathway, including ATA 842, in preclinical development. Our T-cell product candidates arise from a platform technology designed to produce off-the-shelf, partially human leukocyte antigen matched cellular therapeutics. We licensed these product candidates from Memorial Sloan Kettering Cancer Center in June 2015. Our initial T-cell product candidates target viral- or cancer-specific antigens and are des
