ON24, Inc. reports shareholder litigation related to its planned merger with Cvent Atlanta’s affiliate and issues supplemental proxy disclosures ahead of the March 26, 2026 special meeting. Two stockholders filed suits in New York seeking to block or alter the merger, claiming the original proxy omitted material information.
ON24 believes these claims are without merit but is voluntarily expanding its disclosures to reduce delay risk. New details cover non-disclosure agreements (clarifying there were no post-signing “don’t-ask don’t-waive” provisions), the absence of pre-signing employment or participation talks for management, and added specificity around Goldman Sachs’ fairness opinion.
The filing outlines ON24’s cash and fully diluted share assumptions, valuation ranges per share, and peer transaction and trading multiples used in the analysis. It also discloses long-term financial projections through 2035, including revenue, margins, operating expenses, stock-based compensation and unlevered free cash flow, and reiterates extensive forward‑looking statement and merger‑completion risks.
ON24, Inc. reports its annual business overview, highlighting a cloud-based intelligent engagement platform that helps B2B sales and marketing teams run interactive webinars, virtual events and personalized content experiences, increasingly powered by AI through its ACE analytics and content engine.
The company serves 1,539 customers across technology, financial services, life sciences, manufacturing and professional services, with no single customer contributing more than 10% of revenue and about 20% of the Fortune 500 as customers as of December 31, 2025.
ON24 notes that revenue declined 6% in 2025 versus 2024 after strong growth in 2020–2021, reflecting weaker marketing budgets, a shift back to in‑person events and intense competition. Management is emphasizing core, higher-margin products and de‑emphasizing its large managed virtual conference service.
The report also discloses a proposed merger under a December 29, 2025 Merger Agreement with Cvent Atlanta, LLC and Summit Sub Corp., under which Summit Sub would merge into ON24 and ON24 would become a wholly owned subsidiary of the parent, subject to the risks detailed in its Risk Factors.
