ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES |
NOTE 1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
Business Overview
We are a life science technology company that designs, develops, and manufactures advanced sequencing solutions that enable scientists and clinical researchers to improve their understanding of the genome and ultimately, resolve genetically complex problems. Our products and technology, which include our HiFi long-read sequencing technology, address solutions across a broad set of applications including human germline sequencing, plant and animal sciences, infectious disease and microbiology, oncology, and other emerging applications. Our focus is on creating some of the world's most advanced sequencing systems to provide our customers with the most complete and accurate view of genomes, transcriptomes, and epigenomes. Our customers include academic and governmental research institutions, commercial testing and service laboratories, genome centers, public health labs, hospitals and clinical research institutes, contract research organizations ("CROs"), pharmaceutical companies, and agricultural companies. References in this report to “PacBio,” “we,” “us,” the “Company,” and “our” refer to Pacific Biosciences of California, Inc. and its consolidated subsidiaries.
Basis of Presentation and Consolidation
Our unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States, or U.S. GAAP, as set forth in the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC. The unaudited condensed consolidated financial statements include the accounts of Pacific Biosciences and our wholly owned subsidiaries. Certain information and footnote disclosures typically included in our audited financial statements have been condensed or omitted. The accompanying unaudited condensed consolidated financial statements have been prepared on a consistent basis with the December 31, 2024 audited consolidated financial statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state our financial position, results of operations, comprehensive loss, and cash flows for the period, but are not necessarily indicative of the results to be expected for the entire year or any future periods. All intercompany transactions and balances have been eliminated. The financial statements should be read in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2024 (the "2024 Annual Report").
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes to the financial statements. On an ongoing basis, we evaluate our significant estimates, including those relating to the valuation of inventory, fair value of contingent consideration, valuation of acquired intangible assets, useful lives assigned to finite-lived assets, asset impairment assessments, computation of provisions for income taxes, and valuations related to our convertible senior notes. While the extent of the potential impact of current macroeconomic conditions on our business is highly uncertain, we considered information available related to assumptions and estimates used to determine the results reported and asset valuations as of September 30, 2025. Actual results could differ materially from these estimates.
Cash, Cash Equivalents, Restricted Cash, and Investments
We consider all highly liquid investments purchased with an original maturity of 90 days or less to be cash equivalents. Cash equivalents may be comprised of money market funds, certificates of deposit, commercial paper, corporate bonds and notes, and government agencies’ securities. We classify our investments in debt securities as available-for-sale and report the investments at fair value in current assets. We evaluate our available-for-sale investments in unrealized loss positions and assess whether the unrealized loss is credit-related. Unrealized gains and losses that are not credit-related are recognized in accumulated other comprehensive income (loss) in stockholders’ equity. Realized gains and losses, expected credit losses, as well as interest income, on available-for-sale securities are reported in other income, net. The cost used in the determination of gains and losses of securities sold is based on the specific identification method. The cost of marketable securities is adjusted for the amortization of premiums and discounts to expected maturity. Premium and discount amortization is recorded in other income, net. We have the ability to hold, and do not intend to sell investments in unrealized loss positions before the recovery of their amortized cost bases. Our investment portfolio at any point in time contains investments in cash deposits, money market funds, commercial paper, corporate debt securities and U.S. government and agency securities with high credit ratings. We have established guidelines regarding diversification and maturities of investments with the objectives of maintaining safety and liquidity, while maximizing yield. Restricted cash includes cash that is not readily available for use in the Company’s operating activities. Restricted cash is primarily comprised of cash pledged under letters of credit.
Recent Accounting Pronouncements
Accounting Pronouncements Pending Adoption In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This new standard requires a company to expand its existing income tax disclosures, specifically related to the rate reconciliation and income taxes paid. The standard is effective for annual periods beginning in 2025 and is expected to be applied retrospectively. We expect that the adoption of this new standard will result in incremental income tax related disclosures to the notes to the consolidated financial statements but will not have a material impact on the consolidated financial statements. In November 2024, the FASB issued ASU 2024-04, Debt—Debt With Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments. This new standard clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion or extinguishment of convertible debt. The standard will be effective for us beginning in the first quarter of 2026, with early adoption permitted. The new standard is expected to be applied prospectively, but retrospective application is permitted. We do not expect the adoption of this new standard to have a material impact on the consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This new standard requires a company to provide disaggregated disclosures, within the notes to the financial statements, of specified categories of expenses that are included in line items on the face of the income statement. The standard will be effective for us beginning in 2027, and interim periods within 2028, with early adoption permitted. The new standard is expected to be applied prospectively, but retrospective application is permitted. We are currently evaluating the impact of ASU 2024-03 on the consolidated financial statements and related disclosures. In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This new standard clarifies and modernizes the recognition and disclosure framework for capitalized internal-use software costs by removing all references to project stages and introduces a more judgment-based approach. The standard also clarifies the threshold to be applied to begin capitalizing. The standard will be effective for us beginning in the first quarter of 2028, with early adoption permitted, and can be applied using a prospective, retrospective, or modified transition approach. We are currently evaluating the impact of ASU 2025-06 on the consolidated financial statements and related disclosures. Significant Accounting Policies There have been no changes to our significant accounting policies as disclosed in our 2024 Annual Report.
