Current report

The AI technology and features we develop and/or incorporate into our solutions include new and evolving technologies that may present both legal and business risks.

Current report

While we are increasingly incorporating artificial intelligence (“AI”), including machine learning and large language model–based capabilities, into our products, services and internal operations, the use of AI presents risks and challenges that could adversely affect our business. AI technologies are complex, rapidly evolving and may produce outputs that are inaccurate, misleading, biased, incomplete or otherwise flawed, including as a result of errors in underlying algorithms, training data, or inputs. Our customers or other users may rely on such outputs to their detriment, which could expose us to legal claims, regulatory scrutiny, reputational harm or competitive disadvantage.

Current report

In addition, the legal and regulatory framework governing AI is evolving and remains uncertain, including with respect to intellectual property ownership, data privacy, automated decision‑making and liability allocation. Our use of AI, or our integration of third‑party AI technologies into our offerings, may subject us to claims of intellectual property infringement or misappropriation, data protection violations or other legal obligations, including where we have limited contractual recourse against third‑party AI providers. Further, AI technologies may require the processing of personal or sensitive data, increasing our compliance obligations and risk exposure.

Current report

We also permit and increasingly rely on the use of AI tools by our workforce in certain development, analytical and operational contexts. The use of such tools, whether authorized or unauthorized, may create risks related to the protection of confidential information, cybersecurity, data leakage, or the misuse of proprietary or third‑party intellectual property. If we are unable to manage these risks effectively, our business, reputation, financial condition and results of operations could be adversely affected.
Reworded paragraphs (16)

Previous wording

We had an accumulated deficit of $326.2 million as of December 31, 2024. Our net expenses may increase based on the initiatives we undertake which for instance, may include increasing our sales and marketing activities, hiring additional personnel, incurring additional costs as a result of being a public company, acquiring additional businesses and making additional equity grants to our employees. This may result in the reduction of our cash balances or the incurrence of debt.

Previous wording

We received approximately 33% of our revenue from our five largest customers for the year ended December 31, 2024, and the loss of one or more of these customers could adversely impact our results of operations and financial condition.

Current wording

We received approximately 36% of our revenue from our five largest customers for the year ended December 31, 2025, and the loss of one or more of these customers could adversely impact our results of operations and financial condition.

Previous wording

Our five largest customers accounted for approximately 33% of our total revenues for the year ended December 31, 2024. In particular, our customers in the automotive and related services sectors account for a significant portion of our revenue.

Previous wording

If some of our customers experience financial distress or suffer disruptions in their business, their weakened financial position could negatively affect our own financial position and results.

Previous wording

Effective internal controls are necessary for us to provide reliable and accurate financial reports and effectively prevent fraud. We have devoted significant resources and time to comply with the internal control over financial reporting requirements of the Sarbanes-Oxley ("SOX") Act of 2002. In addition, SOX Section 404 requires that we assess and in certain instances for our auditors to attest to the effectiveness of our controls over financial reporting. Our current and future compliance with the annual internal control report requirement will depend on the effectiveness of our financial reporting and data systems and controls across our operating subsidiaries. We expect these systems and controls to become increasingly complex to the extent that we integrate acquisitions and our business grows. To effectively manage this growth, we will need to continue to improve our operational, financial and management controls and our reporting systems and procedures. We cannot be certain that these measures will ensure that we design, implement, and maintain adequate controls over our financial processes and reporting in the future. Any failure to implement required new or improved controls, or difficulties encountered in their implementation or operation, could harm our operating results, or cause us to fail to meet our financial reporting obligations. Inadequate internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our stock and our access to capital.

Previous wording

The actual or perceived improper sending of text messages or voice calls may subject us to potential risks, including liabilities or claims relating to consumer protection laws and regulatory enforcement, including fines. For example, the Telephone Consumer Protection Act ("TCPA") of 1991 restricts telemarketing and the sending of automatic short message service ("SMS") text messages without explicit customer consent. The scope and interpretation of the federal and state laws and regulations that are or may be applicable to the delivery of text messages or voice calls are continuously evolving and developing. If we do not comply with these laws or regulations or if we become liable under these laws or regulations due to the failure of our customers to comply with these laws by obtaining proper consent, we could face direct liability. We rely on contractual representations made to us by our customers that they will comply with our acceptable use restrictions and applicable law and regulations in using our services. We cannot predict whether our role in facilitating our customers’ or other users’ activities would expose us to liability under applicable law.

Previous wording

The Communications Act of 1934, as amended by the Telecommunications Act of 1996 (the “Act”), and the regulations promulgated by the FCC under Title II of the Act, may impose federal licensing, reporting and other regulatory obligations on the Company. To the extent we contract with and use the networks of VoIP service providers, new legislation or FCC regulation in this area could restrict our business, prevent us from offering service or increase our cost of doing business. There are an increasing number of regulations and rulings that specifically address access to commerce and communications services on the Internet, including internet protocol ("IP") telephony. We are unable to predict the impact, if any, that future legislation, legal decisions, or regulations concerning voice services offered via the Internet may have on our business, financial condition, and results of operations.

Previous wording

Federal and state telemarketing laws including the TCPA which limits the use of autodialing systems, artificial or prerecorded voice messages, SMS text messages and fax machines, the Telemarketing Sales Rule, the Telemarketing Consumer Fraud and Abuse Prevention Act and the rules and regulations promulgated thereunder. In recent years, the TCPA has become a fertile source for both individual and class action lawsuits and regulatory actions. Specifically, the TCPA restricts telemarketing and the transmission of automatic SMS text messages without proper consent. The scope and interpretation of the laws and regulations that are or may be applicable to the delivery of text messages and/or to the allowable methods of obtaining proper consent are continuously evolving and developing. If we do not comply with these laws or regulations or if we become liable under these laws or regulations due to the failure of our customers to comply with these laws by obtaining proper consent, we could face liability. In addition, certain regulatory developments in this area may adversely impact the demand for some of our services (e.g. our text analytics and communications services) if some our customers become unable to obtain proper consents for their communications at historical volumes.

Previous wording

The Telephone Robocall Abuse Criminal Enforcement and Deterrence Act and the rules and regulations promulgated thereunder. The FCC has adopted rules requiring originating and terminating voice service providers to implement the STIR/SHAKEN caller identification ("ID") authentication framework to combat spoofed robocalls and is expected to adopt additional measures for that purpose. A number of our information services depend on integrations with voice service providers subject to these regulations. We maintain a registration in FCC’s Robocall Mitigation Database as a Non-Gateway Intermediate Provider. If we do not comply with our providers’ evolving requirements pertaining to these regulations or if future regulatory measures relative to the STIR/SHAKEN caller ID authentication framework result in unforeseen interoperability issues for our information services that we are unable to address in a timely and efficient manner, our business, financial condition, and results of operations could be negatively impacted and/or we could face liability.

Previous wording

Laws affecting telephone call recording and associated consent requirements. Under the Federal Wiretap Act, at least one party taking part in a call must be notified if the call is being recorded. Under this law, and most state laws, there is nothing illegal about one of the parties to a telephone call recording the conversation. However, a number of states (i.e. California, Connecticut, Delaware, Florida, Illinois, Maryland, Massachusetts, Montana, Nevada, New Hampshire, Pennsylvania, and Washington) require that all parties consent when one party wants to record a telephone conversation. The telephone recording laws in other states, like federal law, require only one party to be aware of the recording. The scope of the consent requirements under these laws may expand over time based on evolving case law in this area.

Laws in most states of the United States of America may require registration or licensing of one or more of our subsidiaries, and may impose additional taxes, fees or telecommunications surcharges on the provision of our services which we may not be able to pass through to customers.

Previous wording

We may also be subject to costs and liabilities with respect to privacy issues. Several companies have incurred penalties for failing to abide by the representations made in their public-facing privacy policies. In addition, a significant number of U.S. states have enacted laws that require businesses and their service providers to implement and maintain reasonable security procedures and practices to protect personal information and to provide notice to consumers in the event of a security breach. For example, California enacted the California Consumer Privacy Act, which was subsequently amended by the California Privacy Rights Act of 2020 (collectively, “CPRA”), which went into effect on January 1, 2023. The CPRA gives California residents rights to access, correct, and delete their personal information, opt out of certain types of personal information sharing, limit the use of sensitive personal information as well as receive detailed information about how their personal information is retained and used. The CPRA and the regulations promulgated thereunder also include requirements for provisions to be included by businesses in their respective contracts with service providers, which limit the scope of permissible use for personal data processed as part of the services and give businesses certain rights to assess their service providers’ data processing operations. The CPRA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. Multiple other states have enacted privacy-related legislation that provides for consumer rights similar to the CPRA. Further, it is anticipated that additional federal and state privacy-related legislation may be enacted. Such legislation could negatively affect our business in various ways such as by increasing our and/or our customers’ costs of compliance. Finally, the majority of the aforementioned privacy laws and regulations do not apply to information historically regulated by certain industry-specific legislation and regulations such as the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) and/or the Gramm-Leach-Bliley Act, each of which include separate sets of security standards for the processing of covered data and provide for significant civil and/or criminal penalties for violations. To the extent that we increase our market share of conversational analytics offerings for customers in the healthcare and/or financial services industries, our risk of possible costs and liabilities related to compliance with these additional laws increases as well.

In addition, the stock market in general, and the NASDAQ, the market for technology companies in particular, have experienced significant price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the listed companies. These broad market and industry factors may seriously harm the market price of our Class B common stock, regardless of our operating performance. In the past, following periods of volatility in the market, securities class action litigation has often been instituted against these companies.

Previous wording

As of December 31, 2024, Russell C. Horowitz, our founder, beneficially owned 100% of the outstanding shares of our Class A common stock, which shares represented 75% of the voting power of all outstanding shares of our capital stock. The holders of our Class A common stock and Class B common stock have identical rights except that the holders of our Class B common stock are entitled to one vote per share, while holders of our Class A common stock are entitled to twenty-five votes per share on all matters to be voted on by stockholders. This concentration of control could be disadvantageous to our other stockholders with interests different from those of our founder. This difference in the voting rights of our Class A common stock and Class B common stock could adversely affect the price of our Class B common stock to the extent that investors or any potential future purchaser of our shares of Class B common stock give greater value to the superior voting rights of our Class A common stock.

We are also subject to Section 203 of the Delaware General Corporation Law ("DGCL"), which provides, subject to enumerated exceptions, that if a person acquires 15% or more of our voting stock, the person is an “interested stockholder” and may not engage in “business combinations” with us for a period of three years from the time the person acquired 15% or more of our voting stock. The application of the DGCL could have the effect of delaying or preventing a change of control of our company.
