## Exhibit 99.1

**Exhibit 99.1**

**PacBio Announces First Quarter 2026 Financial Results**

**MENLO PARK, Calif.,** May 7, 2026 (GLOBE NEWSWIRE) – PacBio (NASDAQ: PACB) today announced financial results for the quarter ended March 31, 2026.

**Recent Business Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Selected by Basecamp Research to power its Trillion Gene Atlas, which is expected to result in approximately 100,000 samples being deeply sequenced from over 31 countries

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Announced a collaboration with DNAstack to power the first global federated HiFi whole genome dataset

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Expanded SPRQ-Nx beta program to more customers domestically and internationally after receiving positive feedback from initial users

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• EMEA revenue grew by 17% year-over-year as a result of increased consumables demand reflecting both account expansion and higher utilization, particularly in clinical settings

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Named Lucid Genomics as a PacBio Compatible partner for tertiary analysis of data generated on PacBio's long-read sequencing instruments

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Completed sale of short-read sequencing assets for net cash proceeds of approximately $48.1 million, strengthening the balance sheet and extending cash runway

"We continue to see increasing clinical adoption of HiFi which contributed to another record quarter for consumable revenue. However, instrument revenue, particularly Vega, was lower than we had expected," said Christian Henry, President and Chief Executive Officer. "Nonetheless, we made significant progress on several important initiatives, such as our expansion of the SPRQ-Nx beta program based on the positive early feedback on the new chemistry. Based on this success, we plan to execute a broad commercial rollout to all Revio customers later this month, which we believe will further catalyze consumable growth and Revio instrument demand. Additionally, we continue to prove our ability to win large-scale projects as we were selected by Basecamp Research to power the Trillion Gene Atlas, which has the potential to produce the largest and most diverse high-fidelity metagenomic dataset in the world."

Gross margin, operating expenses, net loss, and net loss per share are reported on a GAAP and non-GAAP basis. The non-GAAP measures are described below and reconciled to the corresponding GAAP measures at the end of this release.

We recorded a GAAP gross profit of $12.8 million during the first quarter of 2026 compared to a GAAP gross loss of $1.4 million during the first quarter of 2025. GAAP gross loss for the first quarter of 2025 reflected charges related to our restructuring announced April 9, 2025 and included $7.7 million in restructuring-related inventory charges, $4.3 million of amortization of acquired intangible assets, and a $4.1 million loss on purchase commitments. Non-GAAP gross profit for the first quarter of 2026 was $13.8 million compared to non-GAAP gross profit of $15.0 million for the first quarter of 2025. GAAP gross margin was 35% for the first quarter of 2026 compared to a negative GAAP gross margin of 4% for the first quarter of 2025. Non-GAAP gross margin was 37% for the first quarter of 2026 compared to a non-GAAP gross margin of 40% for the first quarter of 2025. The decline in Non-GAAP gross margin was primarily driven by increased computing component costs, temporary first quarter promotions for Vega and inventory and warranty-related adjustments and charges.

------

GAAP operating expenses totaled $21.2 million for the first quarter of 2026, compared to $427.6 million for the first quarter of 2025. GAAP operating expenses for the first quarter of 2026 included $16.3 million of litigation settlement charges and related legal fees, and a gain on disposal of assets of approximately $45.8 million. GAAP operating expenses for the first quarter of 2025 include $381.8 million of charges associated with the Company's restructuring efforts and re-focus on its long-read business, partially offset by an $18.7 million decrease in the change in the fair value of contingent consideration. Non-GAAP operating expenses totaled $49.9 million for the first quarter of 2026, compared to $61.7 million for the first quarter of 2025. GAAP and non-GAAP operating expenses for the first quarter of 2026 and the first quarter of 2025 included non-cash share-based compensation of $3.8 million and $8.0 million, respectively.

GAAP net loss for the first quarter of 2026 was $8.3 million, compared to $426.1 million for the first quarter of 2025. Non-GAAP net loss for the first quarter of 2026 was $35.9 million, compared to $44.4 million for the first quarter of 2025.

GAAP net loss per share for the first quarter of 2026 was $0.03, compared to $1.44 for the first quarter of 2025. Non-GAAP net loss per share for the first quarter of 2026 was $0.12, compared to $0.15 for the first quarter of 2025.

**2026 Financial Outlook**

PacBio expects revenue for the full year 2026 to be in the range of $165 million to $175 million.

PacBio products are provided for Research Use Only. Not for use in diagnostic procedures.

**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 (loss) 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 acquired intangible assets and changes in fair value of contingent consideration, and further excludes infrequent and limited charges including impairment charges, restructuring-related expenses for discrete restructuring events, settlement charges, disposition of short-read assets, 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 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 as well as the expected financial impact and timing of these plans and initiatives, including our expectations regarding SPRQ-Nx; PacBio's financial guidance and expectations for future periods; new and continued reception of PacBio's products and their expansion into new or existing markets; our expectations regarding our collaboration with Basecamp Research; developments affecting our industry and the markets in which we compete, including the impact of new products and technologies and tariffs; anticipated results of studies and future customer use and costs of our products and consumables, including the increasing clinical adoption of HiFi; and the availability, uses, accuracy, coverage, advantages, quality or performance of, or benefits or expected benefits of using, PacBio products or technologies. 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; risks related to PacBio's ability to successfully execute and realize the benefits of acquisitions; the impact of new, increased or enhanced tariffs and export restrictions; rapidly changing technologies and extensive competition in genomic sequencing; unanticipated increases in costs or expenses; high costs of computer memory components; 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 global economic or political instability, including war and other international conflicts, such as the conflicts in the Middle East. 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.
