Company Context

Arthur J. Gallagher & Co. (AJG) is one of the largest global insurance brokerage, risk management, and consulting firms, with more than $10B in annual revenue and operations across brokerage, benefits consulting, and claims/risk services. The company has historically grown through a mix of acquisitions and producer-led organic expansion, competing with large global brokers such as Marsh McLennan, Aon, and WTW, while also facing regional and specialist brokers in the middle market.

Strategic Situation

You are a strategy candidate interviewing for a role on AJG's corporate strategy team. The CEO has asked for a point of view on where AJG should focus its next phase of U.S. brokerage growth over the next 24 months. Specifically, AJG must decide whether to prioritize middle-market commercial clients (companies with $25M-$1B in revenue), specialty verticals (e.g., construction, transportation, healthcare), or small business/digital distribution. The decision matters now because pricing in several commercial lines is stabilizing after a hard market, acquisition multiples for brokers remain elevated, and clients are demanding more advisory support around cyber, employee benefits, and total cost of risk.

Data Points

Additional facts:

• AJG's current U.S. brokerage revenue mix is approximately 55% middle market, 30% specialty, and 15% small business/personal lines-adjacent channels.
• AJG has a 6% share in middle market, 4% share in specialty verticals, and less than 1% in digital small business brokerage.
• Management has approved up to $150M of incremental investment over two years for hiring producers, digital capabilities, and selective tuck-in acquisitions.
• The board expects any strategy to deliver at least $120M of incremental annualized revenue by year 3 and meet a pre-tax ROIC hurdle of 15%.

Deliverables

1. Size the opportunity across the three growth paths and identify which segment offers the best balance of scale, growth, and economics.
2. Assess AJG's competitive position versus large global brokers, specialists, and digital-first entrants.
3. Recommend one primary growth focus for the next 24 months, with a clear rationale.
4. Outline a go-to-market plan, including whether AJG should lean more on organic growth, acquisitions, partnerships, or digital investment.
5. Identify the key risks and the metrics management should track.

Constraints

• Recommendation must fit within the $150M investment envelope.
• AJG cannot pursue all three paths equally; management wants a single primary focus with one secondary capability investment.
• The plan should show meaningful results within 24 months, even if full payoff occurs by year 3.
• Any recommendation must be consistent with AJG's relationship-driven brokerage model and decentralized operating structure.
