Basis of Presentation | |
Basis of Presentation | (1) Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by Celldex Therapeutics, Inc. (the “Company” or “Celldex”) in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and reflect the operations of the Company and its wholly-owned subsidiary. All intercompany balances and transactions have been eliminated in consolidation. These interim financial statements do not include all the information and footnotes required by U.S. GAAP for annual financial statements and should be read in conjunction with the audited financial statements for the year ended December 31, 2020, which are included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 29, 2021. In the opinion of management, the interim financial statements reflect all normal recurring adjustments necessary to fairly state the Company’s financial position and results of operations for the interim periods presented. The year-end condensed balance sheet data presented for comparative purposes was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for any future interim period or the fiscal year ending December 31, 2021. At June 30, 2021, the Company had cash, cash equivalents and marketable securities of $164.0 million. The Company has had recurring losses and incurred a loss of $29.9 million for the six months ended June 30, 2021. Net cash used in operations for the six months ended June 30, 2021 was $30.0 million. The Company believes that the cash, cash equivalents and marketable securities at the filing date of this Form 10-Q will be sufficient to meet estimated working capital requirements and fund planned operations for at least the next twelve months from the date of issuance of these financial statements. During the next twelve months and beyond, the Company may take further steps to raise additional capital to meet its long-term liquidity needs including, but not limited to, one or more of the following: the licensing of drug candidates with existing or new collaborative partners, possible business combinations, issuance of debt, or the issuance of common stock or other securities via private placements or public offerings. Although the Company has been successful in raising capital in the past, there can be no assurance that additional financing will be available on acceptable terms, if at all, and the Company’s negotiating position in capital-raising efforts may worsen as existing resources are used. There is also no assurance that the Company will be able to enter into further collaborative relationships. Additional equity financings may be dilutive to the Company’s stockholders; debt financing, if available, may involve significant cash payment obligations and covenants that restrict the Company’s ability to operate as a business; and licensing or strategic collaborations may result in royalties or other terms which reduce the Company’s economic potential from products under development. The Company’s ability to continue funding its planned operations beyond twelve months from the issuance date is also dependent on the timing and manner of payment of contingent milestones from the acquisition of Kolltan Pharmaceuticals, Inc. (“Kolltan”), in the event that the Company achieves the drug candidate milestones related to those payments. The Company, at its option, may decide to pay those milestone payments in cash, shares of its common stock or a combination thereof. If the Company is unable to raise the funds necessary to meet its long-term liquidity needs, it may have to delay or discontinue the development of one or more programs, discontinue or delay ongoing or anticipated clinical trials, license out programs earlier than expected, raise funds at a significant discount or on other unfavorable terms, if at all, or sell all or a part of the Company. In December 2019, a novel strain of coronavirus, now referred to as COVID-19, surfaced in Wuhan, China. The virus continues to spread globally, has been declared a pandemic by the World Health Organization and has spread to hundreds of countries, including the United States. The impact of this pandemic has been and will likely continue to be extensive in many aspects of society, which has resulted in and will likely continue to result in significant disruptions to the global economy, as well as businesses and capital markets around the world. In an effort to halt the outbreak of COVID-19, various states, including New Jersey, Massachusetts and Connecticut, where the Company has office, research and manufacturing facilities, have placed significant restrictions on travel and many businesses have announced extended closures which could adversely impact our operations. To date, the Company has not experienced significant delays or disruptions in planned and ongoing preclinical and clinical trials, manufacturing or shipping. Potential impacts to our business include delays in planned and ongoing preclinical and clinical trials including enrollment of patients, disruptions in time and resources provided by independent clinical investigators, contract research organizations, and other third-party service providers, temporary closures of our facilities, disruptions or restrictions on our employees’ ability to travel, and delays in manufacturing and/or shipments to and from third party suppliers and contract manufacturers for APIs and drug product. Any prolonged negative impacts to our business could materially impact our operating results and could lead to impairments of our Intangible in-process research and development (“IPR&D”) assets with a carrying value of $30.7 million at June 30, 2021. |

Significant Accounting Policies | |
Significant Accounting Policies | (2) Significant Accounting Policies The significant accounting policies used in preparation of these condensed consolidated financial statements on Form 10-Q for the three and six months ended June 30, 2021 are consistent with those discussed in Note 2 to the financial statements in our Annual Report on Form 10-K for the year ended December 31, 2020. Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s consolidated financial statements upon adoption. In June 2016, the FASB issued guidance on the Measurement of Credit Losses on Financial Instruments. The guidance requires that credit losses be reported using an expected losses model rather than the incurred losses model that is currently used, and establishes additional disclosures related to credit risks. For available-for-sale debt securities with unrealized losses, the standard now requires allowances to be recorded instead of reducing the amortized cost of the investment. This standard will be effective for the Company on January 1, 2023. We are currently evaluating the potential impact that this standard may have on the Company’s consolidated financial statements and related disclosures. |

The Company values its marketable securities utilizing independent pricing services which normally derive security prices from recently reported trades for identical or similar securities, making adjustments based on significant observable transactions. At each balance sheet date, observable market inputs may include trade information, broker or dealer quotes, bids, offers or a combination of these data sources. The following table reflects the activity for the Company’s contingent consideration liabilities measured at fair value using Level 3 inputs for the six months ended June 30, 2021 (in thousands): Other Liabilities: Contingent Consideration Balance at December 31, 2020 $ 8,267 Fair value adjustments included in operating expenses 741 Balance at June 30, 2021 $ 9,008 The valuation technique used to measure fair value of the Company’s Level 3 liabilities, which consist of contingent consideration related to the acquisition of Kolltan in 2016, was primarily an income approach. The significant unobservable inputs used in the fair value measurement of the contingent consideration are estimates including probability of success, discount rates and amount of time until the conditions of the milestone payments are met. As of June 30, 2021, the weighted average discount rate used in calculating the fair value of contingent consideration was 6.3% (with a range of 5.9% to 7.4%) and the weighted average amount of time until the conditions of the milestone payments are met was 3 years. During the three and six months ended June 30, 2021, the Company recorded a $0.3 million and $0.7 million loss on fair value remeasurement of contingent consideration, respectively, primarily due to changes in discount rates and the passage of time. During the three and six months ended June 30, 2020, the Company recorded a $5.1 million and $4.9 million gain on fair value remeasurement of contingent consideration, respectively, primarily due to updated assumptions for CDX-3379 related milestones due to the discontinuation of the CDX-3379 program and the passage of time. The assumptions related to determining the fair value of contingent consideration include a significant amount of judgment, and any changes in the underlying estimates could have a material impact on the amount of contingent consideration adjustment recorded in any given period. The Company did not have any transfers in or out of Level 3 assets liabilities during six |

The unrealized losses are attributable to changes in interest rates and the Company does not believe any unrealized losses represent other-than-temporary impairments. Marketable securities include $0.3 million and $0.2 million in accrued interest at June 30, 2021 and December 31, 2020, respectively. |

Intangible Assets | |
Intangible Assets | (5) Intangible Assets At June 30, 2021 and December 31, 2020, the carrying value of the Company’s indefinite-lived intangible assets was $30.7 million. Indefinite-lived intangible assets consist of acquired IPR&D related to the development of the anti-KIT program (including CDX-0159) and the TAM program, a broad antibody discovery effort to generate antibodies that modulate the TAM family of RTKs, comprised of Tyro3, AXL and MerTK. CDX-0159 is in Phase 1 development and the TAM program is in preclinical development. As of June 30, 2021, none of the Company’s IPR&D assets had reached technological feasibility nor did any have alternative future uses. The Company performs an impairment test on IPR&D assets at least annually, or more frequently if events or changes in circumstances indicate that IPR&D assets may be impaired. As a result of the discontinuation of the CDX-3379 program in the second quarter of 2020, the Company concluded that the CDX-3379 IPR&D asset was fully impaired and a non-cash impairment charge of $3.5 million was recorded in the second quarter of 2020. As a result of a change in the projected development and regulatory timeline related to the TAM program in the fourth quarter of 2020, the Company concluded that the TAM IPR&D asset was partially impaired and a non-cash impairment charge of $14.5 million was recorded in the fourth quarter of 2020. Due to the nature of IPR&D projects, the Company may experience future delays or failures to obtain regulatory approvals to conduct clinical trials, failures of such clinical trials or other failures to achieve a commercially viable product, and as a result, may recognize further impairment losses in the future. |

(“Cantor”) to allow the Company to issue and sell shares of its common stock from time to time through Cantor, acting as agent. At June 30, 2021, the Company had $50.0 million remaining in aggregate gross offering price available under the Company’s November 2020 prospectus. In July 2021, the Company issued 6,845,238 shares of its common stock in an underwritten public offering resulting in net proceeds to the Company of approximately $270.0 million, after deducting underwriting fees and offering expenses.

Revenue | (10) Revenue Product Development and Licensing Revenue The Company’s agreement with Rockefeller University, as amended, (the “Rockefeller Agreement”) provides for the Company to perform manufacturing and development services for Rockefeller University for their portfolio of antibodies against HIV. This portfolio was licensed to Gilead Sciences in January 2020 from Rockefeller University (“Rockefeller Transaction”). Pursuant to the Rockefeller Agreement, the Company received an upfront payment of $1.8 million as a result of the Rockefeller Transaction which was recorded to revenue during the first quarter of 2020. The Company is eligible to receive additional payments from Rockefeller University if this portfolio progresses through clinical and commercial development. Contract and Grants Revenue The Company has entered into the Rockefeller Agreement and an agreement with Gilead Sciences pursuant to which the Company performs manufacturing and research and development services on a time-and-materials basis or at a negotiated fixed-price. The Company recognized $3.2 million and $3.8 million in revenue under these agreements during the three and six months ended June 30, 2021, respectively, and $0.2 million and $0.6 million during the three and six months ended June 30, 2020, respectively. During the third quarter of 2020, the Company was awarded a Small Business Innovation Research (“SBIR”) grant from the National Institutes of Health (NIH) to support the Company’s CDX-1140 and CDX-301 programs. The Company recognized $0.2 million and $0.3 million in grant revenue under the award during the three and six months ended June 30, 2021. Contract Assets and Liabilities At June 30, 2021 and December 31, 2020, the Company’s right to consideration under all contracts was considered unconditional, and as such, there were no recorded contract assets. At June 30, 2021, the Company had $0.1 million in contract liabilities recorded, which is expected to be recognized during the next 12 months as manufacturing and research and development services are performed. At December 31, 2020, the Company had $3.4 million in contract liabilities recorded. Revenue recognized from contract liabilities as of December 31, 2020 during the three and six months ended June 30, 2021 was $3.0 million and $3.4 million, respectively. |

Income Taxes | |
Income Taxes | (11) Income Taxes The Company has evaluated the positive and negative evidence bearing upon the realizability of its net deferred tax assets and considered its history of losses, ultimately concluding that it is “more likely than not” that the Company will not recognize the benefits of federal, state and foreign deferred tax assets and, as such, has maintained a full valuation allowance on its deferred tax assets as of June 30, 2021 and December 31, 2020. The net deferred tax liability of $1.8 million at June 30, 2021 and December 31, 2020 relates to the temporary differences associated with the IPR&D intangible assets acquired in previous business combinations and is not deductible for tax purposes. A $0.2 million non-cash income tax benefit was recorded during the second quarter of 2020 related to the impairment of the CDX-3379 IPR&D asset and a $0.9 million non-cash income tax benefit was recorded during the fourth quarter of 2020 related to the partial impairment of the TAM program IPR&D asset. Massachusetts, New Jersey, New York and Connecticut are the jurisdictions in which the Company primarily operates or has operated and has income tax nexus. The Company is not currently under examination by these or any other jurisdictions for any tax year. |

Net Loss Per Share | |
Net Loss Per Share | (12) Net Loss Per Share Basic net loss per common share is based upon the weighted-average number of common shares outstanding during the period, excluding restricted stock that has been issued but is not yet vested. Diluted net loss per common share is based upon the weighted-average number of common shares outstanding during the period plus additional weighted-average potentially dilutive common shares outstanding during the period when the effect is dilutive. In periods in which the Company reports a net loss, there is no difference between basic and diluted net loss per share because dilutive shares of common stock are not assumed to have been issued as their effect is anti-dilutive. The potentially dilutive common shares that have not been included in the net loss per common share calculations because the effect would have been anti-dilutive are as follows: Six Months Ended June 30, 2021 2020 Stock Options 4,344,622 3,085,287 Restricted Stock — — 4,344,622 3,085,287 |

Kolltan Acquisition | |
Kolltan Acquisition | (13) Kolltan Acquisition On November 29, 2016, the Company acquired all of the share and debt interests of Kolltan, a clinical-stage biopharmaceutical company, in exchange for 1,217,200 shares of the Company’s common stock plus contingent consideration in the form of development, regulatory approval and sales-based milestones (“Kolltan Milestones”) of up to $172.5 million. The Kolltan Milestone payments, if any, may be made, at Celldex’s sole election, in cash, in shares of Celldex’s common stock or a combination of both, subject to provisions of the Merger Agreement. Certain Kolltan Milestones related to the METRIC clinical study, TAM partnership closing within two years of the acquisition, CDX-3379 and CDX-0158 have been abandoned and, because of this, as of June 30, 2021, the Company believes that the adjusted amount we may be required to pay for future consideration is up to $107.5 million contingent upon the achievement of the Kolltan Milestones. In October 2019, the Company received a letter from Shareholder Representative Services LLC (“SRS”), the hired representative of the former stockholders of Kolltan, notifying the Company that it objected to the Company’s characterization of the development, regulatory approval and sales-based Kolltan Milestones relating to CDX-0158 as having been abandoned and contending instead that the related milestone payments are due from Celldex to the Kolltan stockholder. The Company disagrees with their objection and believes their objection to be without merit. On August 18, 2020, Celldex filed a Verified Complaint in the Court of Chancery of the State of Delaware against SRS (acting in its capacity as the representative of the former stockholders of Kolltan pursuant to the Merger Agreement) seeking declaratory relief with respect to the rights and obligations of the parties relating to certain contingent milestone payments under the Merger Agreement relating to the discontinued CDX-0158 program. Specifically, Celldex sought the entry of an order declaring that: (i) Celldex’s determination to discontinue the development of CDX-0158 (formerly known as KTN0158) was proper and valid under the Merger Agreement; (ii) the Milestone Abandonment Notice dated December 5, 2018 from Celldex was valid and effective under the Merger Agreement and that the “Successful Completion of Phase I Clinical Trial for KTN0158” Milestone has not been achieved and has properly been abandoned; and (iii) under the Merger Agreement, the CDX-0159 program is not a program that results in milestone payments under the Merger Agreement. In SRS’ responsive Answer and Verified Counterclaim, SRS made claims of breach of contract with respect to the Merger Agreement, breach of implied covenant of good faith and fair dealing, declaratory relief, and unjust enrichment regarding abandonment of the CDX-0158 milestones, based in part on SRS’ assertion that the CDX-0159 program is in essence an extension of the CDX-0158 (formerly KTN0158) program. The parties entered into non-binding mediation in May 2021 following SRS’s approach to Celldex about its interest in settlement or mediation discussions, but those discussions did not result in a resolution of the dispute. The case remains ongoing and we are currently unable to predict or estimate the outcome of this matter. The case is currently scheduled for trial in June 2022. Following the Company’s discontinuation of the CDX-3379 program, the Company sent a milestone abandonment notice to SRS with respect to Kolltan Milestones related to the CDX-3379 program. In October 2020, the Company received notice that SRS has objected to that notice, seeking further information from the Company, which was provided pursuant to the terms of the Merger Agreement. |

Recent Accounting Pronouncements | Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s consolidated financial statements upon adoption. In June 2016, the FASB issued guidance on the Measurement of Credit Losses on Financial Instruments. The guidance requires that credit losses be reported using an expected losses model rather than the incurred losses model that is currently used, and establishes additional disclosures related to credit risks. For available-for-sale debt securities with unrealized losses, the standard now requires allowances to be recorded instead of reducing the amortized cost of the investment. This standard will be effective for the Company on January 1, 2023. We are currently evaluating the potential impact that this standard may have on the Company’s consolidated financial statements and related disclosures. |
