Business Combination and Asset Acquisition [Abstract] |
BUSINESS ACQUISITIONS | BUSINESS ACQUISITIONS Apton Biosystems On August 2, 2023, we acquired Apton Biosystems, Inc. (“Apton”), a California-based genomics company focused on developing a high throughput short-read sequencer using highly differentiated optics and image processing, paired with novel clustering and chemistry (the “Apton acquisition”). In connection with the Apton acquisition, all outstanding equity securities of Apton were cancelled in exchange for shares of our common stock with a fair value of $76.6 million, cash of $0.2 million, and contingent consideration with a preliminary estimated fair value of $18.5 million. Excluded from consideration transferred was $1.3 million attributable to accelerated share-based compensation expense. The fair value of the 6,121,571 common shares issued was determined based on the closing market price of our common stock on the acquisition date. In connection with the Apton acquisition, contingent consideration of $25.0 million, which we may elect to pay in cash, shares of our common stock or a combination of cash and shares of our common stock, is due upon the achievement of a milestone, defined as the achievement of $50.0 million in revenue associated with Apton's technology, provided that the milestone event occurs prior to the 5-year anniversary of the closing date of the acquisition. At this time, the number of shares, if any, to be issued in connection with the achievement of the specified milestone is not known and will be calculated based on the daily volume-weighted average price of our common stock for the twenty trading days ending on and including the fifth trading day immediately prior to the occurrence of the specified milestone. Upon achievement of the milestone, we may pay cash in lieu of our common stock to ensure that the issuance of our common stock does not exceed 19.9% of our outstanding shares of common stock then outstanding. The contingent consideration is accounted for as a liability at fair value, with changes during each reporting period recognized in our consolidated statements of operations and comprehensive loss. The fair value of the contingent consideration liability is calculated, with the assistance from a third-party valuation firm, using a Monte Carlo Simulation to estimate the volatility and systematic relative risk of revenues subject to sales milestone payments and discounting the associated cash payment amounts to their present values using a credit-risk-adjusted interest rate. We allocated the consideration transferred to the identifiable assets acquired and liabilities assumed based on preliminary estimates of their respective fair values at the date of the completion of the Apton acquisition, and such allocation is subject to adjustment for up to one year after the close of the acquisition as additional information is obtained. The major classes of assets and liabilities to which we have allocated the total fair value of the consideration transferred, based on the preliminary estimated fair values were as follows (in thousands):
Cash and cash equivalents | $ | 97 |
In-process research and development | 55,000 |
Goodwill | 52,287 |
Other assets, current | 153 |
Deferred income tax liability | (11,338) |
Liabilities assumed | (2,191) |
Total consideration transferred | $ | 94,008 |
The purchase price allocation is preliminary, primarily due to the pending finalization of review of various tax attributes. We continue to collect information regarding certain estimates and assumptions, including potential liabilities and contingencies. We will record adjustments to the fair value of the assets acquired, liabilities assumed and goodwill within the twelve months measurement period, if necessary. During the year ended December 31, 2023, we recorded a measurement period adjustment of $1.6 million to decrease goodwill, and a corresponding $2.0 million increase in intangible assets and $0.4 million decrease in the deferred tax liability on the consolidated balance sheets, and a $0.7 million increase to our benefit from income taxes on the consolidated statements of operations and comprehensive loss. The measurement period adjustment was due to new information that became available to us upon the completion of the valuation assessment of the in-process research and development and the tax provision. We incurred costs related to the Apton acquisition of approximately $9.0 million during the year ended December 31, 2023, which are included in merger-related expenses on the consolidated statement of operations and comprehensive loss. Merger-related expenses include $2.8 million relating to a liquidity event bonus plan that was treated as a separate transaction and included the issuance of 168,621 shares of common stock that were issued with a fair value of $2.1 million based on the closing market price of our common stock on the acquisition date. As a result, the total shares issued in connection with the Apton acquisition were 6.3 million shares of common stock. The excess of the value of consideration paid over the aggregate fair value of those net assets has been recorded as goodwill. We recognized goodwill of $52.3 million, based on preliminary estimates, which is primarily attributable to the synergies expected to occur from the integration of Apton and is not deductible for income tax purposes. We preliminarily allocated $55.0 million of the purchase price to acquired in-process research and development ("IPR&D"). The fair value of the IPR&D was determined, with the assistance of a third-party valuation firm, using an income approach based on a forecast of expected future cash flows. Expected future cash flows utilize significant assumptions such as assumed revenue projections and discount rate. Omniome, Inc. On September 20, 2021, we completed our acquisition of Omniome, Inc. (“Omniome”), a San Diego-based company, to obtain their proprietary short-read DNA sequencing platform capable of delivering high accuracy (the “Omniome acquisition”). In connection with the Omniome acquisition, all outstanding equity securities of Omniome were cancelled in exchange for approximately $315.7 million in cash, 8,911,580 shares of our common stock with a fair value of $249.4 million and contingent consideration with a fair value of $168.6 million. The fair value of the 8,911,580 common shares issued was determined based on the closing market price of PacBio’s common shares on the acquisition date. In addition, approximately $18.9 million, comprised of $7.4 million of cash, 226,811 shares of our common stock with a fair value of $6.3 million, and $5.2 million related to contingent consideration, was accounted for as a one-time post-acquisition share-based compensation expense. This share-based compensation expense was due to accelerated vesting of Omniome stock awards in connection with the acquisition. In connection with the acquisition the contingent consideration of $200 million (composed of $100 million in cash and $100 million in shares of our common stock) is due upon the achievement of a milestone, defined as the first commercial shipment to a customer of a nucleotide sequencing platform, comprising both an instrument and related consumables, that utilizes SBB technology. The number of shares of stock to be issued will be determined using the volume-weighted average of the trading prices of our common stock for the twenty trading days ending with and including the trading day that is two days immediately prior to the achievement of the milestone. Of the $100 million in shares of our common stock to be issued as part of the milestone, $4.1 million was attributable to stock options issued by PacBio in replacement of Omniome’s unvested options as part of the transaction. Upon achievement of the milestone, shares will be issued not in excess of an amount equal to 19.9% of our outstanding shares of common stock on the date of closing (prior to the issuance of any shares issued in connection with the transaction or the related private placement), less 11,500,000 shares. The contingent consideration is accounted for as a liability at fair value, with changes during each reporting period recognized in our Consolidated Statements of Operations and Comprehensive Loss. The fair value of the contingent consideration liability is calculated, with the assistance from a third-party valuation firm, using a scenario-based method that considers a range of possible outcomes and their assigned probabilities of occurrence. The potential outcomes are discounted to present value at a discount rate equal to the sum of the term-matched risk-free-interest rate plus PacBio’s credit spread. On September 20, 2023, we achieved the commercial milestone in connection with the acquisition of Omniome. See Note 5. Financial Instruments for additional information on amounts paid and shares issued to former Omniome securityholders during the year ended December 31, 2023. Total consideration transferred for the acquisition is as follows (in thousands):
Total cash paid | $ | 315,703 |
Fair value of share consideration | 249,435 |
Fair value of contingent consideration | 168,574 |
Less: Share-based compensation expense excluded from consideration transferred | (18,923) |
Total consideration transferred | $ | 714,789 |
The acquisition was accounted for as a business combination and, accordingly, the total fair value of the consideration transferred was allocated to the tangible and intangible assets acquired and liabilities assumed based on their fair values on the acquisition date. As of December 31, 2021, the major classes of assets and liabilities to which we have allocated the total fair value of the consideration transferred were as follows (in thousands):
Cash and cash equivalents | $ | 15,338 |
Property and equipment, net | 6,123 |
Operating lease right-of-use assets, net | 18,095 |
In-process research and development | 400,000 |
Goodwill | 390,665 |
Other assets, non-current | 3,203 |
Deferred income tax liability | (91,814) |
Liabilities assumed | (26,821) |
Total consideration transferred | $ | 714,789 |
During the year ended December 31, 2021, we recorded a measurement period adjustment of $1.6 million to decrease goodwill and a corresponding $0.4 million to decrease the deferred tax liability on the Consolidated Balance Sheet, and a $1.2 million decrease to our benefit from income taxes on the Consolidated Statements of Operations and Comprehensive (Loss) Income. The measurement period adjustment was due to new information that became available to us upon the completion of the IRC Section 382 Tax Study, where we identified additional net operating losses that are available to us from acquired assets. Refer to Note 9 – Income Taxes, in Part II, Item 8 of the Annual Report on Form 10-K for the year ended December 31, 2021 for more information. There were no measurement period adjustments recorded in the year ended December 31, 2022. The goodwill recognized was primarily attributable to the assembled workforce and synergies that are expected to occur from the integration of Omniome and is not deductible for income tax purposes. We incurred costs related to the Omniome acquisition of approximately $12.0 million during the twelve months ended December 31, 2021, which are included in merger-related costs on the Consolidated Statement of Operations and Comprehensive (Loss) Income. No significant merger-related costs were incurred during the twelve months ended December 31, 2022. The following unaudited pro forma financial information presents combined results of operations for each of the periods presented as if Omniome had been acquired as of the beginning of 2020, giving effect on a pro forma basis to the purchase accounting adjustments such as $12.0 million of PacBio acquisition-related costs, $18.9 million of share-based compensation expense related to acceleration of certain Omniome stock options not attributable to pre-combination service, and a $91.0 million one-time income tax benefit from the reduction of our deferred tax asset valuation allowance resulting from the Omniome acquisition, as well as a pro forma adjustment to reflect $16.7 million of Omniome’s acquisition-related costs. The unaudited pro forma information presented below is for informational purposes only and is not necessarily indicative of the consolidated results of the combined business had the acquisition actually occurred at the beginning of 2020 or the results of future operations of the combined business. The following table summarizes the unaudited pro forma financial information:
| Years Ended December 31,
(in thousands, except per share amounts) | 2021 |  | 2020
Pro forma total revenue | $ | 130,513 |  |  | $ | 78,893 |
Pro forma net (loss) income | $ | (278,451) |  |  | $ | 17,510 |
Pro forma net (loss) income per share - basic and diluted | $ | (1.27) |  |  | $ | 0.09 |
Our consolidated financial statements include the results of operations for Omniome beginning September 20, 2021. Revenues of $0 and a net loss of $15.6 million from the acquired Omniome business have been included in our Consolidated Statement of Operations and Comprehensive (Loss) Income for the twelve months ended December 31, 2021. Circulomics, Inc. On July 20, 2021, we acquired Circulomics Inc. (“Circulomics”), a Maryland-based biotechnology company focused on delivering highly differentiated sample preparation products that enable genomic workflows (the “Circulomics acquisition”). We paid $29.5 million in cash in exchange for all outstanding shares of common stock of Circulomics. We allocated the consideration transferred to the identifiable assets acquired and liabilities assumed based on their respective fair values at the date of the completion of the Circulomics acquisition. The major classes of assets and liabilities to which we have allocated the total fair value of the consideration transferred were as follows (in thousands):
Cash and cash equivalents | $ | 987 |
Property and equipment, net | 214 |
Intangible assets | 11,360 |
Goodwill | 19,309 |
Other assets, non-current | 467 |
Deferred income tax liability | (2,672) |
Liabilities assumed | (118) |
Total consideration transferred | $ | 29,547 |
The excess of the value of consideration paid over the aggregate fair value of those net assets has been recorded as goodwill. We recognized goodwill of $19.3 million, which is primarily attributable to the synergies expected from capabilities in extraction and sample preparation and is not deductible for income tax purposes. We recorded $11.4 million for the fair value of acquired intangible assets, which consists of developed technology and customer relationships.
