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.

1 serious warning sign in Gogo’s filings.

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 27 Feb 2026, plus the 10-Q filed 6 Aug 2026 and 4 later 8-Ks.

  • Weak checks on its own accounts

    Serious

    The company said its checks on its own accounts did not work at the end of its latest quarter. Mistakes could slip into the numbers.

    “Based upon this evaluation, our Chief Executive Officer and the Chief Financial Officer have concluded that our disclosure controls and procedures were not effective as of June 30, 2026 due to a material weakness in internal control over financial reporting which, as previously disclosed in Part II, Item 9A “Controls and Procedures” in the 2025 10-K, existed as of December 31, 2025 and, as discussed below, continued to exist as of June 30, 2026.”
    Show the full paragraph
    Management, with the participation of our Chief Executive Officer and the Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of June 30, 2026. Based upon this evaluation, our Chief Executive Officer and the Chief Financial Officer have concluded that our disclosure controls and procedures were not effective as of June 30, 2026 due to a material weakness in internal control over financial reporting which, as previously disclosed in Part II, Item 9A “Controls and Procedures” in the 2025 10-K, existed as of December 31, 2025 and, as discussed below, continued to exist as of June 30, 2026.

    From the 10-Q filed 6 August 2026, Part I, Item 4. Controls and Procedures. Read it in the filing

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 carries a lot of debt: 8.3× its equity.

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 use of new and evolving technologies, such as AI, in our products and services may result in reputational harm, competitive harm or legal liability.

    Could happen
    Additionally, the IP ownership and license rights of new technologies such as AI have not been fully addressed by U.S. courts, and the use or adoption of such technologies in our products and services may expose us to potential intellectual property claims, breach of a data or software license, website terms of service claims, claimed violations of privacy rights or other tort claims. There is already active product liability and wrongful death lawsuits in the US alleging that AI technologies have contributed to serious harm, including suicide, which underscores the potential for significant legal exposure and reputational harm.

  • The use of new and evolving technologies, such as AI, in our products and services may result in reputational harm, competitive harm or legal liability.

    Could happen
    Additionally, the EU AI Act strictly regulates AI abroad. Other jurisdictions may decide to adopt similar or more restrictive legislation rendering the use of such technologies challenging. To date, there is no unified legal definition of “artificial intelligence” nor a set standard of regulations, making compliance vary significantly from region to region, especially within the U.S. This lack of harmonization increases the complexity and cost of compliance, and may create uncertainty regarding our legal obligations. Social and ethical issues relating to the use of new and evolving technologies such as AI in our offerings could also harm our competitive position and brand, or create legal liability, and may cause us to incur additional research and development costs to resolve such issues. Investors, analysts, and other market participants may use AI tools to process, summarize, or interpret our financial information or other data about us. The use of AI tools in financial and market analysis may introduce risks similar to those described above, including an inaccurate interpretation of our financial or operational performance or market trends or conditions, which in turn could result in inaccurate conclusions or investment recommendations. Lastly, the rapid evolution and increased adoption of AI technologies may intensify our cybersecurity risks. For more information, see “— We periodically are and could be in the future adversely affected if we or our third party suppliers or service providers suffer service interruptions or delays, technology failures, damage to equipment or system disruptions or failures arising from, among other things, force majeure events, cyberattacks or other malicious activities. ”

  • Assertions by third parties of infringement, misappropriation or other violations by us of their intellectual property rights could result in significant costs and materially adversely affect our business and results of operations.

    In February 2022, a competitor filed a patent infringement suit against us. On November 24, 2025, a jury awarded the competitor $22.7 million in damages. Aspects of the verdict are subject to post-trial briefing, and depending on the outcome, we will appeal if necessary. For more information, see Note 17, “Commitments and Contingencies—SmartSky Litigation,” to our consolidated financial statements. Should an appeal be necessary, the process is likely to be time-consuming and costly and divert management resources, and could adversely affect our business relating to such disputed technology during its pendency.

  • We periodically are and could in the future be adversely affected if we or our third party suppliers or service providers suffer service interruptions or delays, technology failures, damage to equipment or system disruptions or failures arising from, among other things, force majeure events, cybersecurity incidents or other malicious activities.

    Could happen
    To date, no cybersecurity incident has, individually or in the aggregate, resulted in a cybersecurity incident with a material effect on our operations or our financial condition, results of operations, liquidity, or cash flows, but they could have a material impact in the future. A cybersecurity incident or disruption could also interfere with our ability to comply with financial reporting requirements or result in loss of competitive position, litigation, breach of contracts, reputational harm, damage to our stakeholder relationships, or legal liability. While we may be entitled to damages if our third-party service providers fail to satisfy their cybersecurity-related obligations to us, any award may be insufficient to cover our damages, or we may be unable to recover such award. Additionally, future or past business transactions (such as acquisitions or integrations) could expose us to additional cybersecurity risks and vulnerabilities, as our systems could be negatively affected by vulnerabilities present in acquired or integrated entities’ systems and technologies. Furthermore, we may identify cybersecurity issues that were not found during due diligence of such acquired or integrated entities, and it may be difficult to integrate companies into our information technology environment and security program. In addition, system failures, significant interruptions, or cybersecurity incidents could subject us to regulatory scrutiny and enforcement actions (including penalties, fines, and investigations), and result in claims of material breaches of our customer contracts resulting in termination rights, penalties or claims for damages. Regulators’ or others’ scrutiny of cybersecurity, including new laws, regulations, or industry standards, could increase our compliance costs and operational burdens, especially as regulatory and legislative focus on cybersecurity matters intensifies. Regulators, customers, or others may scrutinize us for any actual or suspected system disruptions or cybersecurity incidents. Data protection laws and regulations in the jurisdictions where we operate often require “reasonable,” “appropriate” or “adequate” technical and organizational cybersecurity measures, and the interpretation and application of those laws and regulations are often uncertain and evolving; there can be no assurance that our cybersecurity measures will be deemed adequate, appropriate or reasonable by a regulator or court. We may incur higher costs to comply with laws related to, or regulators’ scrutiny of, our use, collection, management, or transfer of data and other privacy practices.

  • The price of our common stock may be volatile, and the value of your investment could decline.

    In addition, the stock markets have experienced extreme price and volume fluctuations in recent years that have affected and continue to affect the market prices of equity securities of many technology companies. Stock prices of many such companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. These broad market fluctuations may adversely affect the trading price of our common stock. In the past, following periods of volatility in the market price of a company’s securities, class action litigation has often been instituted against such company. Any litigation of this type brought against us could result in substantial costs and a diversion of our management’s attention and resources, which may have a material adverse effect on our business, financial condition and results of operations. Additionally, given the volatility in the stock market in general and in the trading price of our common stock in particular, we continue to actively monitor our common stock’s trading price. If the minimum bid price of our common stock were to fall below $1.00 for a period of more than 30 consecutive trading days, we would become deficient under the Nasdaq listing rules and would then have a period to cure before possibly becoming subject to delisting. Any future deficiency, or the perception among investors that we are at heightened risk of becoming deficient, could negatively affect the market price and trading volume of our common stock.
