"integration of Microsoft's Model Context Protocol (MCP), an open standard that enables AI"

A model context protocol is a set of rules or guidelines that determine how a financial model interprets and applies information within a specific situation. It helps ensure consistent and accurate analysis by clarifying what data or assumptions are relevant in a given scenario. For investors, it provides clarity on how predictions or assessments are made, increasing confidence in decision-making.

azure ai foundry technical

Azure AI Foundry is a managed platform and set of tools for building, deploying and maintaining artificial intelligence applications on the Azure cloud. Think of it as a factory line that helps teams turn data and models into working features faster and with fewer mistakes. For investors, it matters because it can speed time to market, lower development risk and create recurring cloud revenue and customer lock‑in, all of which can affect growth and profitability.

restricted stock units financial

"received an equity award of 22,970 shares of Class A Common Stock in the form of restricted stock units"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

The integration of Microsoft MCP connects Copilot directly to live campaigns, moving AI from pilot to production

LONDON, UK AND CANNES, FR / ACCESS Newswire / June 23, 2026 / Stagwell (NASDAQ:STGW), the challenger network transforming marketing through AI, today announced an industry-first launch of the integration of Microsoft's Model Context Protocol (MCP), an open standard that enables AI to securely connect to live data, tools and workflows, where the Copilot agent is embedded directly into Stagwell's global media agency Assembly's paid search operations and live campaigns. The solution demonstrates how AI can move beyond testing and support day‑to‑day marketing at scale by connecting Copilot directly to Microsoft Advertising data and systems, enabling continuous analysis, auditing and generation of client‑ready outputs.

As one of the first agency integrations of MCP at scale, this deployment creates a direct connection into Agents, allowing it to optimise and analyse within live campaigns. This launch establishes a new benchmark for how agencies can operationalise AI by connecting Agents directly to media systems, standardising workflows across markets and enabling continuous optimisation without adding complexity.

The solution has already been deployed across a global enterprise technology client, demonstrating how AI can transform paid search operations at scale. 

Key outcomes include: 

• Increased audit frequency, shifting from periodic reviews to continuous optimisation 

• Broader coverage across markets, accounts, and campaign types 

• Greater consistency in recommendations across global teams 

• More senior resource redirected toward strategic growth initiatives 

"Stagwell and Assembly are redefining how modern marketing organizations operationalize AI. Using M365 Copilot, Microsoft Advertising MCP, and Azure AI Foundry, they've reduced campaign audit timelines from hours to minutes while building a scalable foundation for AI-driven transformation across media and marketing," said Lydia Smyers, VP US Telco, Media & Gaming, Microsoft.  

"This is not AI as a toolset. This is AI as infrastructure, embedded into how our media segments operate in Search, and beyond, at Stagwell," said Dan Roberts, Global SVP Search at Stagwell Media Platform.  

"This work shows what happens when AI moves beyond pilots into real-world deployment," said Thomas O'Donnell, Global Agencies Director at Microsoft Advertising. "MCP enables a new generation of agents that can securely connect to the systems businesses rely on every day, unlocking entirely new ways of working." 

 This Microsoft Advertising MCP will plug into Stagwell's new media operating system, The Media Machine which launched last week.  This partnership comes after a strong year of momentum for Stagwell in AI and media following the launches of The Machine, Stagwell's agentic operating system for marketing, Stagwell Media Platform, Stagwell Search+ and Agent Cloud. The MCP-powered Copilot agent extends this vision - connecting deep craft specialism with AI execution at scale.
