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 5 Aug 2026 and 9 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

Cheap for a reason is the question the numbers cannot answer.

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.

  • We may not be able to achieve the expected benefits of the NGCS Acquisition. We may also encounter significant difficulties in integrating NGCS.

    Could happen
    We may not be able to achieve the expected benefits of the NGCS Acquisition. There can be no assurance that the NGCS Acquisition will be beneficial to us. We may not be able to integrate the assets acquired in the NGCS Acquisition without increases in costs or other difficulties. The integration of a business is a complex, costly and time-consuming process. As a result, we will be required to devote significant management attention and resources to integrating our business practices and operations with the business practices and operations of NGCS. The integration process may disrupt our business and, if implemented ineffectively, would restrict the full realization of the anticipated benefits from the NGCS Acquisition. The failure to meet the challenges involved in integrating NGCS and to realize the anticipated benefits of the NGCS Acquisition could have an adverse effect on our business, results of operations, financial condition and prospects, as well as the market price of our common stock. The challenges of integrating the operations of acquired businesses include, among others:

  • We may not be able to achieve the expected benefits of the NGCS Acquisition. We may also encounter significant difficulties in integrating NGCS.

    Could happen
    The market price of our common stock may decline as a result of the NGCS Acquisition if, among other things, the integration of the properties acquired in the NGCS Acquisition is unsuccessful or transaction costs related to the NGCS Acquisition are greater than expected. The market price of our common stock may decline if we do not achieve the perceived benefits of the NGCS Acquisition as rapidly or to the extent anticipated by us or by securities market participants or if the effect of the NGCS Acquisition on our business, results of operations or financial condition or prospects is not consistent with our expectations or those of securities market participants.

  • Information Technology and Cybersecurity Risks

    Could happen
    ​ ​ In an executive order issued in January 2021, the former administration asked the heads of all executive departments and agencies to review and take action to address any federal regulations, orders, guidance documents, policies and any similar agency actions promulgated during the prior administration that may be inconsistent with or present obstacles to the administration’s stated goals of protecting public health and the environment, and conserving national monuments and refuges. The executive order also established an Interagency Working Group on the Social Cost of Greenhouse Gases, which is called on to, among other things, capture the full costs of GHG emissions, including the “social cost of carbon,” “social cost of nitrous oxide” and “social cost of methane,” which are “the monetized damages associated with incremental increases in greenhouse gas emissions,” including “changes in net agricultural productivity, human health, property damage from increased flood risk, and the value of ecosystem services.” In early 2025, however, the new administration disbanded the Working Group and withdrew all of its published guidance, ordering EPA to review whether and how to use the social cost of carbon in federal permitting and regulatory decisions and directing the agencies in the meantime to follow OMB regulatory analysis guidance from 2003 that is virtually silent on climate. The current administration also released a series of executive orders impacting the energy sector, ranging from declaring a national emergency due to the U.S.’s inadequate energy supply, infrastructure, and prices, to halting wind energy leasing and promoting fossil fuel exploration. These executive orders are already reshaping the current direction of the U.S. climate agenda and have led to rulemaking actions by EPA that are beginning to undo U.S. climate regulation, including a February 12, 2026 final rule overturning the 2009 CAA endangerment finding respecting GHGs and all federal GHG emissions standards for vehicles and engines. At this time, we cannot determine how the current administration will continue to proceed and cannot accurately predict the ensuing impact of climate-related policy shifts on our business, financial condition, results of operations and cash flows.

  • Our sustainability initiatives, including emissions reduction and our public statements and disclosures regarding the same, expose us to numerous risks.

    Could happen
    As of December 31, 2025, we were in compliance with all covenants under the Debt Agreements, excluding the 2034 Notes, which were issued in January 2026 and not subject to covenant compliance as of December 31, 2025. See Note 15 (“Long-Term Debt”) for further details.
  • Information Technology and Cybersecurity Risks

    Could happen
    Congress and various federal and state legislative and regulatory bodies have previously considered legislation to restrict or regulate emissions of GHG. Energy legislation and other initiatives continue to be proposed that may be relevant to GHG emissions issues. For example, the SEC adopted rules in March 2024 that would have mandated extensive disclosure for certain public companies of climate-related data, risks and opportunities, including financial impacts, physical and transition risks, related governance and strategy, and greenhouse gas emissions. The SEC stayed those rules in April 2024, however, and in March 2025 voted not to defend the rules against ongoing legal challenges. Those legal challenges remain in abeyance pending an SEC decision on whether to rescind, repeal, or modify the rules but, in the meantime, the SEC climate rules remain suspended and without effect.
