THE QUESTION FACING EVERY AI INVESTOR Where will the value of AI accrue? GLOBAL AI INVESTMENT, CUMULATIVE $1T+ deployed into AI — overwhelmingly into a handful of horizontal foundation - model players racing for general intelligence. The harder question for investors is not whether AI matters. It is where the durable value will live. THE HORIZONTAL ARMS RACE 6 major players competing for general intelligence — OpenAI, Anthropic, Google DeepMind, Meta, Mistral, xAI. $100M+ per training run. Only a handful of organizations on earth can compete. ~0 durable moat. Benchmarks rotate quarterly; open - weight models close the gap. THE IMPLICATION: the model is becoming a commodity. The durable value is shifting to what gets built on top — proprietary data and domain depth. © 2026 Mobilewalla Inc. | Public Investor Presentation | May 2026

THE THESIS From commodity models to defensible AI If the algorithm is a commodity, value moves to data, domain expertise, and delivery. THE PROVEN TRUTH Better Data = Better AI Now the consensus of every major AI lab. For forty years the field chased the algorithm — but the algorithm was never the bottleneck. The data was. And proprietary, longitudinal data that compounds over time is the one moat that cannot be compressed in time. THE FRONTIER Vertical AI Purpose - built systems that combine foundation models with proprietary domain data, specialized retrieval, expert evaluation, and agentic architectures — to solve problems that horizontal AI fundamentally cannot touch. HORIZONTAL Broad but shallow · hallucination - prone · capital - intensive · no durable moat VERTICAL Deep & authoritative · grounded and cited · defensible · built on commodity models © 2026 Mobilewalla Inc. | Public Investor Presentation | May 2026

THE OPPORTUNITY Vertical AI is largely unoccupied territory Industries where AI is foundational to operations — yet production - grade vertical AI is scarce or absent today. TELECOM Competitive intelligence, network planning, churn prediction, regulatory monitoring. CONSUMER CREDIT Billions of consumers globally have no credit history. Behavioral data can fill the gap. INSURANCE Risk scoring, claims analysis, fraud detection. Telematics is only the beginning. ENERGY & UTILITIES Demand forecasting, grid optimization, and outage prediction across distributed loads. HEALTHCARE Clinical decision support, population health, drug - interaction modeling. RETAIL Site selection, store performance, micro - market pricing, and location - targeted marketing. Each is a large, fast - growing market — and in most, production - grade vertical AI has barely arrived. © 2026 Mobilewalla Inc. | Public Investor Presentation | May 2026 KC1

THE TIMING The agentic AI window is open — and almost entirely horizontal Agents are how vertical intelligence gets delivered. The market is exploding; the vertical lanes are empty. $7.8B → $52B AGENTIC AI MARKET BY 2030 ~46% CAGR (industry forecasts) ~25% OF GENAI ENTERPRISES have launched an agentic pilot (Deloitte, 2026) 2026 "THE BREAKOUT YEAR" for vertical agentic AI (Rakuten Symphony, 2026) HORIZONTAL AGENTS — WELL - FUNDED, CROWDED The incumbents dominate the headlines: Salesforce Agentforce Horizontal CRM, sales, service workflows. Microsoft Copilot Agents Office 365 and Dynamics workflows. ServiceNow Now Assist IT service management, HR, workflow. VERTICAL AGENTS — NASCENT, MASSIVE WHITESPACE In most verticals — telecom, credit, insurance, energy, healthcare, retail — agentic AI has barely moved past pilot. The build is hard. The data requirements are deep. The domain - expertise barrier is real. These are exactly the conditions in which first movers compound advantage. Gartner, 2025: under 5% of enterprise apps embed task - specific AI agents. © 2026 Mobilewalla Inc. | Public Investor Presentation | May 2026

INTRODUCING MOBILEWALLA Built for this moment Founded 2012. Over a decade of investment in the foundational asset of the AI era. WHAT WE ARE Mobilewalla is a Vertical & Agentic AI company. We have spent more than a decade building what the AI industry is now recognizing as the missing layer: research - grade, longitudinal, proprietary consumer data — engineered at exabyte scale and enriched through computational pipelines that are themselves years of original research. Today that platform powers a family of Vertical AI products across telecom, consumer credit, and consumer data — with a repeatable playbook for many more. THE PLATFORM A decade - deep, longitudinal consumer data foundation — proprietary, global, continuously updated. THE PRODUCTS Vertical AI applications: Telescope, Market Flow, LendBetter, and the Consumer Data Platform. THE PLAYBOOK One platform, many verticals. Every new product compounds the R&D that came before it. © 2026 Mobilewalla Inc. | Public Investor Presentation | May 2026

THE FOUNDATION The Mobilewalla Data Platform The asset that will be difficult to replicate — because the moat is depth + time, not volume. 2B+ devices 40+ countries 10 yrs of history 100s features / device Global Behavioral Footprint Proprietary signals from billions of devices across dozens of countries — continuously refreshed. Engineered Data Pipeline Fraud removal, identity resolution, longitudinal aggregation, and feature computation. Longitudinal Depth A decade of time - series history. Every behavior in context — the dimension that cannot be compressed. Research - Grade Features Hundreds of derived features per device — behavioral, contextual, network, household. Defensible work. WHY THIS IS THE MOAT A competitor can replicate any single piece. They cannot replicate ten years of longitudinal computation on a proprietary sig nal base. © 2026 Mobilewalla Inc. | Public Investor Presentation | May 2026

HOW WE BUILD The Mobilewalla Vertical AI Stack Every MW product is built on the same five - layer architecture — the data and the stack are the moat. 5 Evaluation & Improvement Domain benchmarks, expert - in - the - loop, production feedback loops 4 Agentic Orchestration Query decomposition, multi - source routing, self - verification, citation 3 Retrieval System (RAG) Multi - index: structured DBs, embeddings, knowledge graphs, time - series 2 Task - Specific Fine - Tuning Domain reasoning, structured querying, document extraction 1 Domain - Adapted Base Model Continued pretraining on domain corpus; fluency with domain concepts FOUNDATION MODEL (GPT - class, Claude, Llama, etc.) — the commodity layer WHERE MW WINS The model is the floor. MW's data and stack are the moat. Layers 1 – 5 are where MW's proprietary data, domain depth, and decade of engineering compound. The same stack, re - pointed at a new domain corpus, becomes the next vertical product. © 2026 Mobilewalla Inc. | Public Investor Presentation | May 2026

THE PRODUCTS Vertical AI products on one platform Each product is a derivative of the same proprietary data foundation and the same VAI stack. TELESCOPE Agentic AI for Telecom A multi - agent platform answering natural - language competitive - intelligence questions with grounded, cited responses. Specialized agents for coverage, pricing, network quality, news, and regulatory intelligence. MARKET FLOW Telecom Competitive Intelligence Subscriber - level market - share and flow analytics, churn - risk heatmaps, and coverage monitoring across fiber, 5G, satellite, and fixed wireless — at fine geographic granularity.

Telecom (Market Flow + Telescope) Scale to additional operators; convert agentic AI from beta to commercial. LendBetter Deepen the emerging - market footprint and extend model performance. New verticals Launch insurance, energy, and beyond on the same VAI stack. ENGINE 2 — INORGANIC Data layer Acquire companies that add proprietary data signals or client scale. Vertical analytics layer Acquire complementary players to broaden product coverage. Lending data layer Add alternative - credit data that deepens the scoring edge. Public currency Use public equity as acquisition currency in a consolidating market. THE PLAYBOOK: acquire revenue + team + data, then consolidate onto the Mobilewalla platform to eliminate cost overlap and compound the moat. © 2026 Mobilewalla Inc. | Public Investor Presentation | May 2026

WHY NOW A convergence of timing 1 AI's center of gravity is shifting from horizontal to vertical The race for general intelligence is consolidating. Enterprise demand is moving to AI that is grounded, auditable, and embedd ed in operationally critical workflows. 2 Agentic AI has crossed from demo to deployment The stack required to ship production - grade vertical agents is mature, and the enterprise budget cycle is opening to it. 3 Proprietary data has been re - rated as a strategic asset The market has internalized what the AI labs have known for years: durable advantage in AI lives in the data layer, not the m ode l layer. 4 A decade of foundational investment is now monetizable across verticals Mobilewalla's platform took ten years to build. That work is done. It is now a starting point for many vertical AI businesses, n ot a destination. © 2026 Mobilewalla Inc. | Public Investor Presentation | May 2026

THE INVESTMENT THESIS Five conviction points 1 Data is the durable moat of the AI era. The algorithm is becoming infrastructure. Proprietary, longitudinal data is the asset that cannot be commoditized. 2 Vertical AI is where value will accrue. Horizontal AI is a capital - intensive race with thin differentiation. Vertical AI is where defensible economics live. 3 Grounded agentic delivery is the defensible product. Multi - agent systems built on proprietary data — grounded, cited, embedded in workflow — earn premium enterprise pricing. 4 One platform unlocks many Vertical AI businesses. MW's data foundation is engineered to power many vertical applications. Each new vertical compounds the R&D. 5 The first - mover window in Vertical Agentic AI is open now. Under 5% of enterprise apps embed task - specific AI agents (Gartner, 2025) — and in vertical lanes, almost none. That window will not stay open forever. © 2026 Mobilewalla Inc. | Public Investor Presentation | May 2026
