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 Feb 2026, plus the 10-Q filed 30 Jul 2026 and 3 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 modification, reduction, elimination, or expiration of government subsidies, economic incentives, eligibility limitations, tax incentives, renewable energy targets, and other support for on-grid solar electricity applications, or the impact of other public policies, such as tariffs or other trade remedies imposed on solar cells and modules or related raw materials or equipment, have, and in the future could, negatively impact demand and/or price levels for our solar modules and limit our growth or lead to a reduction in our net sales or increase our costs, thereby adversely impacting our operating results.

    Could happen
    • United States — Port Fees on Certain Chinese Vessel Operators and Chinese Vessel Owners. On April 17, 2025, the Office of the U.S. Trade Representative published a notice of final action based on an investigation under Section 301 of the Trade Act of 1974 into China’s targeting of the maritime, logistics, and shipbuilding sectors for dominance. The action imposes new port fees on Chinese vessel operators and/or Chinese vessel owners as well as on non-Chinese operators of Chinese-origin vessels beginning on October 14, 2025. The level of fees is on a sliding scale per net ton or, in the case of non-Chinese operators, the higher of a net ton or container-based fee. Effective November 10, 2025, however, the United States suspended implementation of such action for one year. Once implemented, such fees may impact our logistics services and consequently impact our profitability and results of operations.

    Already happened
    • United States — IEEPA Tariffs . In 2025, the U.S. President imposed a series of tariffs on nearly all U.S. trading partners pursuant to the International Emergency Economic Powers Act of 1977 (“IEEPA”). As it pertains to the countries where we manufacture solar modules, IEEPA tariffs applied to Vietnam (20%), India (25%), and Malaysia (19%). In August 2025, the U.S. President had imposed an additional 25% tariff on India over its purchases of Russian oil, resulting in an overall rate of 50%. On February 20, 2026, the U.S. Supreme Court ruled the IEEPA tariffs unlawful. President Trump responded immediately by revoking the IEEPA tariff actions and imposing new global tariffs pursuant to Section 122 of the Trade Act of 1974 (“Section 122”), which provides for tariffs up to 15% for a period of no more than 150 days. The additional, higher tariffs on imports from these countries has increased the costs of our solar modules manufactured in these countries with respect to our U.S. market. Further, such circumstances have and may continue to impact our ability to sell certain modules into the United States and therefore have and may continue to also impact the operational status of certain of our international manufacturing facilities. As a result, our operating results have and may continue to be adversely impacted by these tariffs.

    Could happen
    • United States — Potential Tariffs on Processed Critical Minerals and Derivative Products, Polysilicon, Robotics and Industrial Machinery. On April 22, 2025, the U.S. Secretary of Commerce initiated an investigation to determine the effects on the national security of imports of processed critical minerals, as well as their derivative products, under Section 232; on July 1, 2025, the U.S. Secretary of Commerce initiated a Section 232 investigation to determine whether imports of polysilicon and its derivatives impair U.S. national security; and on September 2, 2025, the U.S. Secretary of Commerce initiated an investigation to determine the effects on the national security of imports of robotics and industrial machinery under Section 232. The scope of these investigations is potentially broad and may cover materials and equipment used in solar module manufacturing. These investigations may result in the imposition of tariffs or import restrictions, or may remove barriers on the imports of competitor products and materials, all of which could negatively impact demand and/or price levels for our solar modules and limit our growth, lead to a reduction in our net sales, or increase our costs, thereby adversely impacting our operating results.

    Could happen
    • any tariffs that reduce the profitability of contracts, whereby the cost of tariffs exceeds the amount able to be, or willing to be, absorbed by either us or the customer under the provisions of the contract and may lead to us or the customer cancelling such contract, potentially resulting in the reduction of future revenue, the loss of the contractual right to a termination payment from the customer, and potentially the required return of a previously received customer down payment;

    Could happen
    • any reciprocal or other tariffs may place burdens on our customers’ supply chains exclusive of module import costs, including through increased costs of trackers, inverters, transformers, and other imported equipment, which are often heavily dependent on Chinese supply chains. These and other costs could result in an inability for certain projects to generate profitable returns, and may lead to the delay or abandonment of such projects, thereby reducing or removing demand for currently contracted PV module sales; and • any reduction in our ability to profitably import modules from our international manufacturing locations as a result of tariffs or other trade laws could lead to us significantly reducing capacity utilization at certain international manufacturing facilities. Such underutilization may lead to potential impairment of certain international equipment and facilities and may also increase our selling costs and reduce our competitiveness in the market, thereby reducing demand for our modules.
