Marchex Announces Fourth Quarter and Full Year 2025 Results and Archenia Transaction Update

SEATTLE, WA - March 25, 2026 - Marchex, Inc. (NASDAQ: MCHX), which harnesses the power of AI and conversation intelligence to provide actionable insights derived from prescriptive vertical market data analytics, today announced its financial results for the fourth quarter and full year ended December 31, 2025.

Q4 2025 and Full Year 2025 Financial Highlights

Troy Hartless, President of Marchex, commented, "In the fourth quarter, we achieved our goal of the primary completion of our technology platform migration by end of year. While this involved our migrating approximately 1,000 customers to the new platform and some resulting revenue dilution and offsets, we believe that we are now in a strong position with our ability to leverage new AI capabilities and rapidly deliver innovated solutions to our customers. With this significant infrastructure project behind us, in 2026 we believe that we are well positioned to focus on accelerating our revenue growth and margin expansion."

THE FOLLOWING FORWARD-LOOKING LOOKING STATEMENTS REFLECT MARCHEX'S EXPECTATIONS AS OF MARCH 25, 2026

Revenue in the first quarter of 2026 reflects the migration revenue dilution from the final platform switch over in December 2025, which impacted revenue run rates entering 2026. With this noted, in the first quarter of 2026 Marchex currently anticipates that revenue will be in the range of fourth quarter 2025 levels, and that Adjusted EBITDA will be $500,000 or more.

With the previously announced proposed acquisition of Archenia, Inc., Marchex and Archenia have created a collaboration framework and have been jointly developing and selling initial products that reflect the combined capabilities of the two companies. Product examples of this collaboration, which leverage Marchex's data and AI signals and Archenia's AI tool sets and user interface, are AI-verified outcomes, which drive increased revenue on a Pay-Per-Event basis, and Conversational AI Agents, which increase customer bookings and

appointment rate. While these efforts are early, Marchex has had initial positive indications of adoption of the combined solutions from existing customers in the Home Services and Auto Services verticals. Marchex believes its ability to sell these and other combined solutions, which reflect the bundling of insights, actions and outcomes, to its installed customer base will be a meaningful revenue growth catalyst in 2026 and beyond.

Based on these and other positive factors, Marchex currently anticipates that for the second quarter of 2026 revenue will sequentially increase as compared to the first quarter of 2026, with Adjusted EBITDA potentially increasing to more than $1 million.

Over the course of the past year, Marchex has significantly expanded its product platform capabilities for customers and prospects. During this time, Marchex has launched its new unified user interface across Marchex's product suite, new vertical AI capabilities, and various other new products and features.

With these ongoing launches on the new technology platform, Marchex currently anticipates that it can see sequential quarterly revenue increases during 2026 and that over the course of the year it can see revenue growth on a run rate basis in the 10% range from 2025 year end levels. The company also currently anticipates that in the course of 2026, the combination of anticipated increasing revenue growth combined with lower overall operating expenses can lead to Adjusted EBITDA margins of 10% or more.

Marchex views itself as a meaningful AI beneficiary based on how rapidly it is now able to leverage AI to develop and deploy new products into its customer base that can deliver high customer value and high company revenue opportunities. Additionally, AI is making the business more agile and efficient to operate. The combination of these factors, including the company's vast amount of first party data and vertical expertise, are key elements in the company's outlook for meaningful business acceleration into the second half of the year assuming the closing of the proposed Archenia transaction and the differential and unique attributes of the combined company.

Archenia Transaction Update

In November 2025, Marchex announced that it had entered into an Agreement in Principle ("AIP") to acquire 100% of the stock of Archenia, Inc. (the "Transaction") from its stockholders (the "Sellers").

A special committee of Marchex's Board of Directors consisting solely of independent directors (the "Special Committee") approved Marchex entering into the AIP because certain of the Sellers are related parties. The AIP contemplates the parties entering into a definitive purchase agreement (the "Definitive Agreement") relating to the Transaction. Conditions to entering into the Definitive Agreement include receipt of audited financial statements of Archenia for such periods as required by SEC rules, and receipt of a customary fairness opinion by a financial advisor selected by the Special Committee. Archenia has engaged RSM US LLP to audit the Archenia financial statements and the Special Committee has engaged Craig-Hallum Capital Group LLC as its financial advisor. Conditions to closing the Transaction shall include approval of the Transaction by a majority of Marchex's disinterested stockholders. The Closing Date, in the event a Definitive Agreement is entered into and the Transaction is approved by disinterested stockholders, is anticipated to occur in June 2026.

Archenia's revenue estimates are based on its unaudited results, and it defines Adjusted EBITDA as net income (loss) from continuing operations before interest, income taxes, depreciation and amortization, stock-based compensation expense, and certain non-recurring, discretionary expenditures incurred at the discretion of the shareholders that are (i) not expected to recur in the ordinary course of business, and (ii) not essential to the continuing operations of the Company.

Benefits of the Potential Combination:

Marchex believes its potential acquisition of Archenia, if successfully consummated, would create a vertically focused, AI-driven customer acquisition and outcome-optimization platform. By integrating deep insights, automated actions, and verifiable outcomes, the potential combined company could have the opportunity to achieve greater revenue scale and growth, higher margins, expanded market reach, and enhanced strategic flexibility.

The company believes that the rapid emergence of AI is accelerating the industry's move to new Pay-Per-Event models, consistent with the capabilities of the potential combined company. Additionally, expanded AI-driven product offerings across insights, actions and outcomes may create more ways to win new business and to bundle solutions that create greater customer value and retention.

Marchex believes the potential combination with Archenia, if successfully consummated, could deliver growth acceleration and improved operating leverage:

Marchex believes the combined ability to sell insights, actions and outcomes would meaningfully expand its addressable market. Additionally, the company believes it would have the ability to offer or bundle Archenia's outcome-based solutions to many of Marchex's insights-based enterprise customers.
