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 2 Mar 2026, plus the 10-Q filed 3 Aug 2026 and 7 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.

  • The foregoing risks apply to the timing, completion and anticipated benefits of the proposed acquisition of the Wilson Companies, which may be delayed or not occur at all, may divert management ’ s attention, or may result in legal proceedings, any of which could negatively impact our operating results and ongoing business. Moreover, if we complete the Wilson Transaction, we may be unable to integrate the operations and business successfully.

    Could happen
    On February 22, 2026, we entered into a Sale and Purchase Agreement (Agreement) to acquire all outstanding shares of Wilson Sons Ultratug Participações S.A and its affiliate Atlantic Offshore Services S.A. (collectively, the Wilson Companies) from Wilson Sons S.A., Ultranav International II, S.A. and Remolcadores Ultratug Limitada (collectively, the Wilson Sellers). The acquisition and related agreements (Wilson Transaction) is subject to the satisfaction (or, where permitted, waiver) of certain conditions set forth in the Agreement, including, among others, (i) the approval of the Brazilian antitrust authority, (ii) the consent of the lenders to the Wilson Companies’ to the change of control, (iii) the absence of any final and non-appealable order from an applicable governmental body that prohibits the transaction or makes the consummation of the transaction illegal, (iv) the delivery of certain financial statements to us to allow the Company to satisfy its reporting obligations with the SEC, and (v) the absence of a Material Adverse Effect as defined in the Agreement. Therefore, the Wilson Transaction may not be completed or may not be completed as timely as expected, and we may be required to pay a termination fee in certain circumstances, as further described in the Agreement.

  • The foregoing risks apply to the timing, completion and anticipated benefits of the proposed acquisition of the Wilson Companies, which may be delayed or not occur at all, may divert management ’ s attention, or may result in legal proceedings, any of which could negatively impact our operating results and ongoing business. Moreover, if we complete the Wilson Transaction, we may be unable to integrate the operations and business successfully.

    Furthermore, failure to complete the Wilson Transaction could adversely affect our business and the market price of our common shares in a number of ways, including to the extent that the current market price of our shares reflects an assumption that the acquisition will be consummated. We also have expended, and continue to expend, significant management time and resources in an effort to complete the acquisition, which may have a negative impact on our ongoing business and operations. The Wilson Transaction may lead to litigation against the parties or their directors and officers, which could be distracting to management and may, in the future, require us to incur significant costs.
