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 24 Nov 2025, plus the 10-Q filed 5 Aug 2026 and 10 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.

  • Changes in laws, regulations or governmental policies and programs involving grants, subsidies and/or other incentives may negatively impact our sale of alternative powered school buses.

    Could happen
    Our production plans and financial projections incorporate federal and state programs supporting adoption of clean fuel technologies into existing school bus fleets by offering grants, subsidies and/or other incentives to partially, or fully, offset the higher price of alternative powered school buses. Changes in government programs and support for these products could impact customer purchasing decisions in future periods, resulting in them buying less, or none, of our alternative powered products. While we manage our product development and production operations to support all power options we offer to our customers, which include diesel, gasoline, propane and all-electric powered school buses, our materials ordering and sales projections incorporate assumptions that the mix of school buses we will produce and sell in future periods will be impacted by customers taking advantage of assistance programs offered by federal and state governments. Changes in such programs could impact customer ordering practices, which could result in sales and/or gross profit amounts varying, potentially significantly, from our original estimates of such amounts.

  • We have recently initiated actions to terminate our defined benefit pension plan during fiscal 2026 and the amount of pension funding required in connection with the termination could be significant due to, among other factors, decreasing interest rates, investments that do not achieve adequate returns and/or the degree of our success in our negotiations with the insurance company from which we will purchase group annuity contracts to pay pension obligations due to participants in future years.

    Could happen
    During fiscal 2025, we began executing a plan that will result in the termination of our frozen defined benefit pension plan (“Pension Plan”) qualified with the Internal Revenue Service during fiscal 2026. Upon making such decision, we transitioned all Pension Plan assets, which were previously comprised primarily of equity and longer-termed fixed income securities, to a money market fund comprised of high quality, highly liquid investments, primarily issued by the U.S. government, having maturities of less than one year to ensure the preservation of principal. While such assets are not as prone to the risk of significant fluctuations in fair value, the return that they earn is more exposed to changes in shorter-term interest rates. A decrease in such interest rates during fiscal 2026 would result in both a reduction in the value of assets and an increase in the amount of pension obligations due to participants during the plan termination process. Additionally, we will have to negotiate with insurance companies on the cost of the group annuity contracts that we plan to purchase to pay the pension obligations due to participants in future years. The funding required in fiscal 2026 in connection with the plan termination is dependent on the return earned by assets placed in trusts for this plan, the level of interest rates used to determine pension obligations due to participants in future periods and the degree of our success in our negotiations with the insurance company from which we purchase group annuity contacts. An adverse impact from any or all of the above discussed factors could result in a significant amount of pension funding during the termination process in fiscal 2026, which would negatively impact our cash flows. Additionally, the plan termination will have a material impact on both our profitability and financial position in fiscal 2026 as we will be required to recognize in our consolidated statements of operations the significant amount of losses deferred in the equity account entitled accumulated other comprehensive loss in connection with the transaction.

  • Our costs to produce, and our ability to sell, our products may be negatively impacted by changes in trade policies and tariffs.

    Recently enacted and/or proposed trade policies and tariffs have increased and/or could increase the cost of components we and/or our suppliers purchase from Canada, China and Mexico, which have increased and/or could increase our cost to produce buses and purchase parts for resale. These enacted and/or proposed trade policies and tariffs could expand to other foreign countries in future periods. We can provide no assurance that we will be able to successfully pass along part or all of our increased costs to our customers, particularly for those customers for which we have executed a contract containing a fixed bus price. Additionally, our ability to increase the sales price we charge for our products could impact customer purchasing decisions in future periods, resulting in them buying less, or none, of our products. We can provide no assurance that our ability to sell our products at reasonable margins, or at all, would not be impaired by the imposition of changes in trade policies and tariffs that may make it more difficult or expensive for us to purchase inventory, which could result in reduced sales, profitability and cash flows.
