The Schall Law Firm, a national shareholder rights litigation firm, announces that it is investigating claims on behalf of investors of Pacific Biosciences of California, Inc. (“PacBio” or “the Company”) (NASDAQ: PACB) for violations of the securities laws.

The investigation focuses on whether the Company issued false and/or misleading statements and/or failed to disclose information pertinent to investors. PacBio preannounced poor top-line results for the first quarter of 2024 on April 16, 2024. The Company also announced a reduction in its full-year guidance for 2024 and revised its long-term guidance for fiscal year 2026. The Company blamed its shortfalls on "an increasing number of customers delay instrument purchases and we experienced some unexpected softness in consumable shipments." Analysts were alarmed by the Company’s performance, indicating it was "far worse than we expected."
