Rule 10b5-1 Trading Plan Framework

The sale was conducted pursuant to a Rule 10b5-1 trading plan that Madden adopted on December 15, 2025. Rule 10b5-1 plans are contractual arrangements that allow company insiders to establish predetermined schedules for buying or selling securities while avoiding concerns about trading during periods when they may possess material nonpublic information. By adopting such a plan in advance, insiders can execute trades according to a fixed schedule regardless of market conditions or corporate developments that might otherwise trigger trading restrictions.

The disclosure indicates that the transaction was made pursuant to a contract, instruction, or written plan for the purchase or sale of equity securities of the issuer that is intended to satisfy the affirmative defense conditions of Rule 10b5-1(c). This designation on the filing serves to inform investors that the transaction was part of a structured, pre-planned arrangement rather than a discretionary trading decision made at the time of the sale.

Madden's Beneficial Ownership Position Post-Transaction

Following completion of the July 23, 2026 sale, Larry Madden continues to hold a significant beneficial ownership stake in Viant Technology. The filing discloses that Madden beneficially owns 425,822 shares of Class A Common Stock on a direct basis. This remaining position represents his ownership interest in the company after the sale of 2,814 shares was completed.

The disclosure of Madden's post-transaction beneficial ownership is a key element of insider trading reports, as it allows investors to understand the extent to which company insiders continue to maintain personal financial stakes in the organization. The substantial share count retained by the CFO may signal continued confidence in the company's direction, even as the executive chose to divest a portion of his holdings through the predetermined trading plan.

Insider Roles and Reporting Obligations

Larry Madden is identified in the disclosure as an Officer of Viant Technology Inc., specifically holding the title of Chief Financial Officer. The filing also indicates that Madden is subject to Section 16 reporting obligations under the Securities Exchange Act of 1934. These reporting requirements obligate corporate insiders, including officers and directors, to publicly disclose their securities transactions involving company stock within specified timeframes.

As CFO, Madden holds a position responsible for managing the company's financial operations, strategy, and reporting. Insider transactions by such senior executives are closely monitored by investors and market analysts, as they may provide insight into management's perspective on the company's valuation and prospects. The public disclosure of these transactions through Form 4 filings ensures that the investment community has access to information about trading activity by those with access to material corporate information.

Timeline and Filing Details

The actual stock sale transaction occurred on July 23, 2026, while the disclosure filing was submitted to the Securities and Exchange Commission on July 27, 2026. This four-day gap between the transaction date and the filing date falls within the standard disclosure timeline required for Form 4 filings, which generally must be submitted within two business days of the transaction. The filing was executed by Madden himself, as indicated by the signature block in the disclosure.

The report indicates that this is an original filing rather than an amended submission, meaning that no prior version of this transaction disclosure exists. The use of transaction code "S" in the filing designation indicates that the transaction was a sale of securities. All information contained in the disclosure was provided as of the filing date of July 27, 2026, and represents the most current public record of this insider transaction.

Investor Considerations for Insider Trading Disclosures

Investors monitoring insider trading activity at Viant Technology may pay attention to the pattern and frequency of securities transactions by executive officers and directors. Individual transactions by insiders may occur for various reasons, including portfolio rebalancing, personal liquidity needs, tax planning, or other personal financial circumstances. A single transaction does not necessarily indicate broader management sentiment regarding the company's business prospects or valuation.

However, when considered in aggregate with other insider transactions over time, patterns of buying or selling activity by senior executives can provide context for investors evaluating the company. The use of a Rule 10b5-1 trading plan, as in this case, indicates a systematic and predetermined approach to executing the sale rather than a discretionary decision made at the moment of trading, which may have different implications for investors interpreting the transaction.

Regulatory Compliance and Transparency Requirements

The filing of Form 4 disclosures by company insiders is a cornerstone of the SEC's insider trading compliance framework. These public reports ensure that investors have access to information about securities transactions conducted by those in positions of trust at publicly traded companies. The detailed requirements for Form 4 filings, including the specification of transaction prices, dates, and the number of securities traded, create a comprehensive public record of insider activity.

The specific disclosures required in this filing, including the weighted average price, the range of individual transaction prices, and the post-transaction beneficial ownership count, provide investors with granular detail about the transaction. This level of transparency is designed to prevent information asymmetries and ensure that the investment community can evaluate insider trading activity with full knowledge of the transaction specifics.

What This Disclosure Means for Shareholders

For Viant Technology shareholders, insider transaction disclosures provide one data point among many to consider when evaluating the company and management's perspective on its value. The fact that CFO Madden continues to maintain a significant ownership position of over 425,000 shares while simultaneously executing a sale of a smaller portion of his holdings may suggest a balanced approach to portfolio management rather than wholesale divestiture of company stock.

Shareholders and prospective investors should consider insider transactions as part of a broader analysis that includes the company's financial statements, earnings guidance, competitive positioning, and industry dynamics. A single insider sale should not be viewed in isolation but rather in the context of overall market conditions, the company's performance, and any patterns of buying or selling activity over time.
