Statement regarding use of non‐GAAP financial measures
PacBio reports non‐GAAP results for basic net income and loss per share, net income, net loss, gross margins, gross profit and operating expenses in addition to, and not as a substitute for, or because it believes that such information is superior to, financial measures calculated in accordance with GAAP. PacBio believes that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. In addition, other companies may calculate similarly titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of PacBio’s non-GAAP financial measures as tools for comparison.
PacBio's financial measures under GAAP include substantial charges that are listed in the itemized reconciliations between GAAP and non‐GAAP financial measures included in this press release. PacBio excludes recurring charges from its non-GAAP financial statements, including amortization of intangible assets and changes in fair value of contingent consideration, and further excludes infrequent and limited charges including impairment charges, gain on debt restructuring, restructuring related expenses for discrete restructuring events, and benefits from income taxes and other adjustments and rounding differences.
Management has excluded the effects of these items in non‐GAAP measures to assist investors in analyzing and assessing past and future operating performance. In addition, management uses non-GAAP measures to compare PacBio’s performance relative to forecasts and strategic plans and to benchmark its performance externally against competitors.
PacBio encourages investors to carefully consider its results under GAAP, as well as its supplemental non‐GAAP information and the reconciliation between these presentations, to more fully understand its business. A reconciliation of PacBio’s non-GAAP financial measures to their most directly comparable financial measure stated in accordance with GAAP has been provided in the financial statement tables included in this press release. PacBio is unable to reconcile future-looking non-GAAP guidance included in this press release without unreasonable effort because certain items that impact this measure are out of PacBio's control and/or cannot be reasonably predicted at this time.
Forward-Looking Statements
This press release contains “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and the U.S. Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact are forward-looking statements, including, but not limited to, statements relating to PacBio's initiatives and the expected financial impact and timing of these plans and initiatives; the availability, uses, accuracy, advantages, quality or performance of, or benefits of using, or expected benefits of using, PacBio products or technologies; expectations with respect to commercialization, development and shipment of PacBio products, including the launch of SPRQ-Nx and its impact on lowering sequencing costs; PacBio’s financial guidance and expectations for future periods, including positioning to drive growth and sharpened strategic focus; new and continued reception of PacBio's products and their expansion into new or existing markets; developments affecting our industry and the markets in which we compete, including anticipated future customer use and costs of our products and consumables; expectations regarding the academic funding environment; expectations regarding integrating HiFi into rare disease genomic testing networks, advancing precision therapies for rare genetic diseases, investigations into SUDC, and expanded capabilities resulting from CiFi, among other future events. Reported results and orders for any instrument system should not be considered an indication of future performance. You should not place undue reliance on forward-looking statements because they are subject to assumptions, risks, and uncertainties and could cause actual outcomes and results to differ materially from currently anticipated results, including, but not limited to, challenges inherent in developing, manufacturing, launching, marketing and selling new products, and achieving anticipated new sales; potential cancellation of existing instrument orders; assumptions, risks and uncertainties related to the ability to attract new customers and retain and grow sales from existing customers; the impact of new increased or enhanced tariffs and U.S. export restrictions on the shipment of PacBio products to certain countries; rapidly changing technologies and extensive competition in, and potential FDA regulatory issues relating to, genomic sequencing; unanticipated increases in costs or expenses; interruptions or delays in the supply of components or materials for, or manufacturing of, PacBio products and products under development; potential product performance and quality issues and potential delays in development timelines; the possible loss of key employees, customers, or suppliers; customers and prospective customers curtailing or suspending activities using PacBio's products; third-party claims alleging infringement of patents and proprietary rights or seeking to invalidate PacBio's patents or proprietary rights; risks associated with international operations; and other risks associated with general macroeconomic conditions and geopolitical instability. Additional factors that could materially affect actual results can be found in PacBio's most recent filings with the Securities and Exchange Commission, including PacBio's most recent reports on Forms 8-K, 10-K, and 10-Q, and include those listed under the caption “Risk Factors.” These forward-looking statements are based on current expectations and speak only as of the date hereof; except as required by law, PacBio disclaims any obligation to revise or update these forward-looking statements to reflect events or circumstances in the future, even if new information becomes available.
