Price checks use the past 12 months to June 2026. Quality checks use five annual reports, the latest for the year to December 2025.

We can't read total debt from the filing, so debt is left out.

Recent profit includes a big one-time charge, so we price the company excluding that charge.

From Form 4 filings: insiders must report trades in their own company's shares within two days.

Warning signs in its filings

Problems the company itself reported to the SEC, in its own words.

None of the warning signs we check for were found.

We look for five warning signs: doubt it can keep going, weak checks on its own accounts, a notice that its past accounts can't be relied on, a change of auditor, and one customer bringing in a big share of sales. We don't check lawsuits, investigations or debt yet.

We checked the auditor's report, internal controls, restatement notices, auditor changes and big customers in the 10-K filed 26 Feb 2026, plus the 10-Q filed 6 Aug 2026 and 12 later 8-Ks.

A 10-K is the yearly report every US company files with the SEC. An 8-K is a short notice of a big event.

What could go wrong

  • It isn't cheap on profits: 53.3× operating profit.

Whether the price already reflects the risks is what the deep dive is for.

What changed in the risks this year

Companies must list what could hurt them each year. These are the parts that changed since last year’s report.

  • The pending Amicus Acquisition may not be completed on the currently contemplated timeline or terms, or at all.

    Could happen
    The consummation of the Amicus Acquisition is subject to the satisfaction or waiver of certain conditions. Satisfaction of a number of the conditions is not within our control, and it is possible that such conditions may prevent or delay or otherwise materially adversely affect our ability to complete the Amicus Acquisition. These conditions include, but are not limited to, approval of the Amicus Acquisition by Amicus’ stockholders and the expiration or termination of the relevant waiting period (as it may be extended) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the rules and regulations promulgated thereunder. Neither we nor Amicus can provide assurance that the conditions to completing the Amicus Acquisition will be satisfied or waived, and accordingly, that the Amicus Acquisition will be completed on the timeline that the parties anticipate or at all. If any condition to the Acquisition is not satisfied, it could delay or prevent the Amicus Acquisition from occurring, which could negatively impact us and our growth prospects.

  • The pendency of the Amicus Acquisition could adversely affect our and/or Amicus’ businesses and operations.

    Could happen
    In connection with the pending Amicus Acquisition, some collaboration partners, vendors or other parties with commercial relationships with either of us or Amicus may delay or defer decisions, which could adversely affect the revenues, earnings, cash flows and expenses of us or Amicus, regardless of whether the Amicus Acquisition is completed. In addition, due to operating covenants in the Agreement and Plan of Merger we entered into with Amicus, Amicus may be unable (without our prior written consent), during the pendency of the Amicus Acquisition, to pursue strategic transactions, undertake significant capital projects or otherwise pursue other actions outside the ordinary course, even if such actions would prove beneficial.
    Read more
  • We have in the past and may in the future pursue acquisitions of other companies or businesses, which could divert our management’s attention, fail to achieve the anticipated benefits and/or expose us to other risks or difficulties.

    Acquisitions could also result in dilutive issuances of equity securities, the incurrence of debt, contingent liabilities, amortization expenses, impairment of goodwill and/or purchased long-lived assets, and restructuring charges, any of which could adversely affect our operating results and financial condition. For example, we have incurred, and plan to incur, significant indebtedness in connection with the Amicus Acquisition. In addition, acquired product candidates, such as BMN 401, may not result in regulatory approval, may not perform as expected, may not be successful, may require significantly greater resources and investments than originally anticipated or may not produce the revenues, earnings or business synergies that we anticipated. As a result, the anticipated benefits of an acquisition may not be realized fully within the expected timeframe or at all or may take longer to realize or cost more than expected, which could materially and adversely affect our business, financial condition, results of operations and growth prospects.

  • We, and the third parties with whom we work, are subject to stringent and evolving U.S. and foreign laws, regulations and rules, contractual obligations, industry standards, policies and other obligations related to data privacy and security. Actual or perceived failure to comply with such obligations by us or the third parties with whom we work could lead to regulatory investigations or actions, litigation, fines and penalties, disruptions of our business operations, reputational harm, loss of revenue or profits, and other adverse business consequences.

    Could happen
    Additionally, the U.S. Department of Justice issued a rule entitled the Preventing Access to U.S. Sensitive Personal Data and Government-Related Data by Countries of Concern or Covered Persons, which places additional restriction on certain data transactions involving countries of concern (e.g., China, Russia, Iran) and covered persons that may impact certain business activities such as vendor engagements, sale or sharing of data, employment of certain individuals, and investor agreements. Violations of the rule could lead to significant civil and criminal fines and penalties. The rule applies regardless of whether data is anonymized, key-coded, pseudonymized, de-identified or encrypted, which presents particular challenges for companies like ours and may impact our ability to transfer data in connection with certain transactions or agreements.
    Read more
  • We may not realize the anticipated benefits from the pending Amicus Acquisition.

    Could happen
    • potential unknown liabilities and unforeseen increased expenses, delays or regulatory conditions associated with the Amicus Acquisition; and • performance shortfalls at one or both of the two companies as a result of the diversion of management’s attention caused by completing the Amicus Acquisition and integrating our and Amicus’ operations.
