AJG vs RYAN: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of September 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. AJG and RYAN share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined AJG and RYAN exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Ryan Specialty Holdings is an international specialty insurance intermediary founded by Patrick Ryan (who also founded Aon). It sits between retail insurance brokers and carriers, operating two core engines: wholesale brokerage (led by RT Specialty, one of the largest E&S and binding-authority platforms in the US) and underwriting management, where its managing general underwriters (MGUs) hold delegated authority from carriers to underwrite niche risks in areas like energy, healthcare, construction, and enterprise risk. It does not take underwriting risk on its own balance sheet; it earns commissions and fees for placing and structuring hard-to-place specialty coverage.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• AJG drivers: Acquisition-led compounding; AssuredPartners integration and synergies.
• RYAN drivers: E&S market tailwind; Delegated underwriting (MGU) mix.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The most cited concern is valuation, as AJG often trades at a large premium to the broader insurance sector and to some peers, leaving little room for disappointment. For RYAN, the biggest near-term risk is insurance-pricing cyclicality: management has pointed to pronounced property-rate declines and intensifying competition, guiding to mid-single-digit organic growth and a modest margin decline for the year, with one quarter guided near zero organic growth.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick AJG if you believe its drivers more; RYAN if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the AJG and RYAN guides.

AJG. AJG reported roughly 28% total revenue growth in Q1 2026, blending about 5% organic growth with large contributions from acquisitions including AssuredPartners. The stock's trailing P/E in the mid-30s to around 40x sits well above the broader insurance industry average, a premium the market has historically assigned to its consistency. Forward multiples look lower on expected earnings growth, but the shares clearly price in continued execution.

RYAN. Ryan Specialty grew Q1 2026 revenue about 15% to roughly $795 million and returned to a quarterly net profit, with adjusted EPS up about 20%. The trailing P/E near 54x looks steep and reflects growth expectations, while the forward multiple near 19x is far lower because analysts expect earnings to catch up. Management trimmed full-year organic growth guidance to mid-single digits and expects some margin decline as property rates soften.

Headline figures (approximate, July 2026): AJG shows market cap ~$56 billion, revenue (ttm) ~$13 billion, q1 2026 revenue ~$4.76 billion, q1 2026 adjusted eps ~$4.47; RYAN shows revenue (ttm) ~$3.0B, q1 2026 revenue ~$795M (up ~15% YoY), organic growth (q1 2026) ~11.8%, adjusted ebitda margin ~29%.

AJG and RYAN are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined AJG and RYAN exposure against your real portfolio. It is not an investment adviser.
