Business Combinations [Abstract] |
Acquisitions | Acquisitions As set forth below, we completed six acquisitions from January 1, 2018 through December 31, 2020, of which four (Pfenex, Icagen, Ab Initio and Vernalis) were accounted for as business combinations and two (Taurus and xCella) were accounted for as asset acquisitions. For business combinations, we applied the acquisition method of accounting. Accordingly, we recorded the tangible and intangible assets acquired and liabilities assumed at their estimated fair values as of the applicable date of acquisition. Except for the Pfenex acquisition, for all other acquisitions, we did not incur any material acquisition related costs. Pfenex Acquisition On October 1, 2020, we acquired Pfenex, which develops next-generation and novel protein therapeutics to improve existing therapies and create new therapies for biological targets linked to critical, unmet diseases using a protein expression technology platform. The preliminary purchase price of $465.1 million included $429.6 million cash consideration paid upon acquisition, and a contingent CVR payment of up to $77.8 million in cash based on a certain specified milestone with an estimated initial fair value of $37.0 million. The CVR will only be paid in full if the milestone is achieved by December 31, 2021. The amount of the CVR included in purchase price was reduced by $1.5 million which was determined to be post-combination expense. The fair value of the CVR liability was determined using a probability adjusted income approach. These cash flows were then discounted to present value using a discount rate based on market participants' cost of debt reflective of the Company, which was 7.1%. The liability is periodically assessed based on events and circumstances related to the underlying milestone, and any change in fair value is recorded in our consolidated statements of operations. In connection with the acquisition, a portion of Pfenex's equity awards that were outstanding and unvested prior to the acquisition became fully vested per the terms of the merger agreement. The acceleration of vesting required us to allocate the fair value of the equity attributable to pre-combination service to the purchase price and the remaining amount was considered our post-combination expense. We paid $17.3 million in cash for equity compensation, which is attributable to pre-combination services and is reflected as a component of the total purchase price paid of $429.6 million. In addition, the fair value of equity compensation attributable to the post-combination service period was $8.7 million.These amounts were associated with the accelerated vesting of stock options previously granted to Pfenex employees and were fully paid in cash, which was recognized as general and administrative expenses during the fourth quarter of 2020. We recorded $20.7 million of acquisition-related costs for legal, severance and other costs in connection with the acquisition within operating expenses in our consolidated statement of operations for 2020. The following table sets forth an allocation of the preliminary purchase price to the identifiable tangible and intangible assets acquired and liabilities assumed, with the excess recorded to goodwill (in thousands):
Cash | $ | 51,407 |
Restricted cash | 200 |
Accounts and unbilled receivables | 1,359 |
Property and equipment, net | 7,823 |
Right-of-use asset | 3,070 |
Other assets | 1,338 |
Intangibles acquired | 385,000 |
Goodwill(1) | 90,750 |
Accounts payable | (6,814) |
Accrued liabilities | (7,379) |
Deferred revenue | (3,908) |
Lease liabilities | (3,070) |
Other liabilities | (1,382) |
Deferred tax liabilities, net | (53,296) |
Total consideration | $ | 465,098 |
(1) Goodwill represents the excess of the purchase price over the preliminary fair value of the underlying assets acquired and liabilities assumed. Goodwill is attributable to the assembled workforce of experienced personnel at Pfenex and expected synergies. None of the goodwill is expected to be deductible for tax purposes. The intangibles acquired and their weighted average useful life are as follows (in thousands, except useful lives):
| Approximate Fair Value | Estimated useful life (in years)
Contractual Relationships: |  |
Alvogen | $ | 114,000 |  | 12
Merck | 117,000 |  | 12
Jazz | 80,000 |  | 17
SII | 49,000 |  | 10
Arcellx | 2,000 |  | 17
Acquired Technologies | 23,000 |  | 10-19
| $ | 385,000 |  |
The fair values of the contractual relationships were based on the discounted cash flow method that estimated the present value of the potential royalties, milestones and collaboration revenue streams derived from the licensing of the related technologies over the estimated contractual relationship period. The fair values of the acquired technologies were based on the discounted cash flow method that estimated the present value of the potential royalties, milestones, collaboration and product revenue streams derived from the licensing of the related technologies over the estimated useful lives. These projected cash flows were discounted to present value using discount rate, which varies from 12% to 15%. The intangible assets acquired are being amortized on a straight-line basis over the estimated useful life. The estimated fair values of assets acquired and liabilities assumed, including deferred tax assets and liabilities, and purchased intangibles are provisional. The accounting for these amounts falls within the measurement period and therefore we may adjust these provisional amounts to reflect new information obtained about facts and circumstances that existed as of the acquisition date. Approximately $2.0 million of revenue and $19.3 million of loss before income taxes of Pfenex were included in the consolidated statement of operations for the year ended December 31, 2020. The following summary presents our unaudited pro forma consolidated results of operations for the years ended December 31, 2020 and December 31, 2019 as if the Pfenex acquisition had occurred on January 1, 2019, which gives effect to certain transaction accounting adjustments, including amortization of acquired intangibles and stock based compensation expense for retained Pfenex employees. The transaction accounting adjustments do not include non-recurring adjustments related to Pfenex's executive salary, board of director compensation, and salary of Pfenex employees involved in the reduction of force as part of the acquisition, estimated to be $7.1 million in 2020 and $4.8 million in 2019. The pro forma financial information is not necessarily indicative of the operating results that would have occurred had the acquisition been consummated as if the date indicated, nor is it necessarily indicative of future operating results (in thousands, except per share amounts):
| Year Ended December 31,
(Unaudited) | 2020 | 2019
Revenue | $ | 189,203 |  | $ | 170,608 |
Net Income (loss) | $ | (60,059) |  | $ | 594,941 |
Net income (loss) per common share: |  |
Basic | $ | (3.71) |  | $ | 31.32 |
Diluted | $ | (3.71) |  | $ | 30.11 |
Taurus Acquisition On September 9, 2020, we acquired Taurus, which discovers and develops novel antibodies from immunized cows and cow-derived libraries. These antibodies feature some of the longest CDR3s of any species, with unique genetic and structural diversity that can enable binding to challenging antigens with application in therapeutics, diagnostics and research. The purchase price of $5.1 million included $4.6 million in cash, and a $0.5 million holdback to satisfy indemnification obligations which will be settled by September 2021. We also issued nontransferable CVRs for up to $4.5 million tied to partnered and internal research and development and for up to $25.0 million as a 25% share of post-clinical Taurus product revenues (including milestone payments) received by us. We accounted for this transaction as an asset acquisition as we concluded that substantially all of the fair value of the gross assets acquired was concentrated in the acquired core technology. The allocation of the consideration was allocated to the acquisition date fair values of acquired assets as follows (in thousands)
Cash | $ | 47 |
Intangibles assets with finite-life - core technologies | 5,005 |
| $ | 5,052 |
The core technology is being amortized on a straight-line basis over the estimated useful life of 10 years. We account for the CVRs in accordance with ASC 450, Contingencies, when the contingency is resolved and the liability becomes payable. None of the CVRs are recognized as of the acquisition date. xCella Acquisition On September 8, 2020, we acquired xCella, an antibody discovery company. xCella's xPloration platform is a proprietary microcapillary platform that can screen single B cells for specificity and bioactivity and will increase Ligand’s antibody discovery throughput and efficiency. We paid $7.1 million in cash (including a $0.5 million holdback to satisfy indemnification obligations which will be settled by September 2021), and issued earnout rights for up to $5.0 million tied to our use of the xCella technology for partnered research and development and for up to $25.75 million as a 25% share of any future milestone payments we received under a certain existing xCella partner arrangement. We evaluated this acquisition in accordance with ASC 805, Business Combinations, to discern whether the assets and operations of xCella met the definition of a business. We accounted for this transaction as an asset acquisition as we concluded that substantially all of the fair value of the gross assets acquired was concentrated in the acquired core technology. The allocation of the consideration was allocated to the acquisition date fair values of acquired assets and assumed liabilities as follows (in thousands):
Cash and other assets | $ | 240 |
Accrued liabilities | (142) |
Deferred tax liabilities, net | (820) |
Intangibles assets with finite-life - core technology | 7,798 |
| $ | 7,076 |
The core technology is being amortized on a straight-line basis over the estimated useful life of 15 years. We account for the earnout rights in accordance with ASC 450, Contingencies, when the contingency is resolved and the liability becomes payable. None of the earnout rights are recognized as of the acquisition date. Icagen Acquisition On April 1, 2020, we acquired the core assets, including its partnered programs and ion channel technology from Icagen and certain of its affiliates. The purchase price of $19.9 million included $15.1 million cash consideration paid upon acquisition, and a CVR of up to $25.0 million of cash payments based on certain revenue milestones with an estimated fair value of $4.8 million. The fair value of the earn-out liability was determined using a probability weighted income approach incorporating the estimated future cash flows from expected future milestones. These cash flows were then discounted to present value using a discount rate based on the market participants' cost of debt reflective of the Company, which was 5.5%. The liability is periodically assessed based on events and circumstances related to the underlying milestones, and any change in fair value is recorded in our consolidated statements of operations. The carrying amount of the liability may fluctuate significantly and actual amount paid may be materially different than the carrying amount of the liability. As the acquisition is not considered significant, pro forma information has not been provided. The results of Icagen have been included in our results of operations since the date of acquisition. The preliminary allocation of the consideration was allocated to the acquisition date fair values of acquired assets and assumed liabilities as follows (in thousands):
Property and equipment, net | $ | 1,173 |
Prepaids and other assets | 588 |
Liabilities assumed | (812) |
Deferred revenue | (3,685) |
Deferred tax assets, net | 861 |
Acquired intangibles | 12,800 |
Goodwill(1) | 9,015 |
| $ | 19,940 |
(1) Goodwill represents the excess of the purchase price over the preliminary fair value of the underlying assets acquired and liabilities assumed. Goodwill is attributable to the assembled workforce of experienced personnel at Icagen and expected synergies. The majority of the goodwill is deductible for tax purposes. Acquired intangibles include $11.1 million of customer relationships and $1.7 million of core technology. The fair values of the customer relationships were based on a discounted cash flow analysis incorporating the estimated future cash flows from these relationships during the contractual term. These cash flows were then discounted to present value using a discount rate of 17%. The fair value of the customer relationships is being amortized on a straight-line basis over the weighted average estimated useful life of 9.6 years. The fair value of the core technology was based on the discounted cash flow method that estimated the present value of the potential royalties, milestones, and collaboration revenue streams derived from the licensing of the related technologies. These projected cash flows were discounted to present value using a discount rate of 17%. The fair value of the core technology is being amortized on a straight-line basis over the estimated useful life of 10 years. The total acquired intangibles are being amortized on a straight-line basis over the estimated useful life of 9.7 years. The estimated fair values of assets acquired and liabilities assumed, including deferred tax assets and liabilities, and purchased intangibles are provisional. The accounting for these amounts falls within the measurement period and therefore we may adjust these provisional amounts to reflect new information obtained about facts and circumstances that existed as of the acquisition date. Ab Initio Acquisition On July 23, 2019, we acquired privately-held Ab Initio, an antigen-discovery company located in South San Francisco, California. Ab Initio has a patented antigen technology that is synergistic with the OmniAb® therapeutic antibody discovery platform, providing our current and potential new partners enhanced capabilities for the discovery of therapeutic antibodies against difficult-to-access cellular targets. Ab Initio has a collaboration agreement with Pfizer to discover novel therapeutic antibodies against an undisclosed target in the GPCR superfamily. The purchase price of $12.0 million included $11.9 million cash consideration paid upon acquisition, net of cash acquired, and $0.15 million cash holdback for potential indemnification claims. As the acquisition is not considered significant, pro forma information has not been provided. The final purchase consideration was allocated to the acquisition date fair values of acquired assets and assumed liabilities as follows (in thousands):
Cash and other assets | $ | 28 |
Accounts payable and accrued liabilities | (83) |
Deferred tax liabilities, net | (146) |
Intangibles assets with finite-life - core technologies | 7,400 |
Goodwill(1) | 4,812 |
| $ | 12,011 |
(1) Goodwill represents the excess of the purchase price over the fair value of the underlying assets acquired and liabilities assumed. Goodwill is attributable to the assembled workforce of experienced personnel at Ab Initio and expected synergies. None of the goodwill is deductible for tax purposes. The fair value of the core technologies was determined based on the discounted cash flow method that estimated the present value of the hypothetical royalty/ milestone streams from the licensing of the antigen-discovery technology and collaboration agreement. These projected cash flows were discounted to present value using a discount rate of 12.0%. The fair value of the core technologies is being amortized on a straight-line basis over the weighted average estimated useful life of approximately 20 years. Vernalis Acquisition In October 2018, we acquired Vernalis, a biotechnology company for $43.0 million, funded through cash on hand. The acquisition of Vernalis increases our overall portfolio of fully-funded programs. As Vernalis' operations are not considered material, pro forma information is not provided. The final purchase consideration was allocated to the acquisition date fair values of acquired assets and assumed liabilities as follows (in thousands):
Cash and cash equivalents | $ | 34,286 |
Restricted cash | 2,836 |
Other assets | 6,383 |
Accounts payable and accrued liabilities | (3,479) |
Restructuring and product reserves | (9,241) |
Deferred revenue | (746) |
Intangibles assets with finite-life - core technologies | 7,000 |
Goodwill | 5,939 |
| $ | 42,978 |
None of the goodwill is deductible for tax purposes. The fair value of the core technologies was based on the discounted cash flow method that estimated the present value of the hypothetical royalty/milestone streams derived from the licensing of the related technologies. These projected cash flows were discounted to present value using a discount rate of 34.0%. The fair value of the core technology is being amortized on a straight-line basis over the weighted average estimated useful life of approximately nine years. We retained the core technology after the sale of Vernalis R&D in December 2020. See further discussion in “Note (2), Sale of Vernalis R&D and Promacta License.”
