Arthur J. Gallagher (AJG): Revisiting Valuation After a 10% Pullback Despite Solid Earnings Growth

Recent Performance and Investment Context

Arthur J. Gallagher (AJG) has quietly slipped around 10% over the past year, even as its revenue and net income both grew at roughly 18% and 20% annually. This sets up an interesting valuation check for long term investors.

See our latest analysis for Arthur J. Gallagher.

That pullback has come even as the 5 year total shareholder return sits at a strong 115.9%, while the recent 90 day share price return of minus 15.7% suggests momentum has cooled as investors reassess near term risks versus that growth record.

If AJG’s re rating potential has you thinking more broadly about insurers, it could be a good moment to scan other solid balance sheet and fundamentals stocks screener (None results) for ideas with similar defensive qualities.

With earnings still climbing and the share price sliding, investors now face a key question: is Arthur J. Gallagher quietly slipping into undervalued territory, or is the market simply baking in years of future growth?

Most Popular Narrative: 18.1% Undervalued

With Arthur J. Gallagher last closing at $252.64 against a narrative fair value near $308, the story points to meaningful upside if its growth path holds.

Successful, disciplined execution of the ongoing M&A strategy including the Assured Partners acquisition and a deep pipeline of additional bolt on deals broadens AJG's geographic reach, service offerings, and client base, serving as a catalyst for both revenue and earnings accretion.

Read the complete narrative.

Want to see the engine behind that upside call? The narrative leans on accelerating earnings, rising margins, and a future multiple that assumes AJG keeps compounding like a structural growth winner. Curious which financial levers do the heavy lifting in that math, and how long they are expected to last? Dive into the full narrative to unpack the projections driving this valuation.

Result: Fair Value of $308 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, structural shifts toward digital disintermediation, as well as a sharper, sustained pullback in property pricing, could undercut AJG’s growth narrative and valuation upside.
