Greg Case
Chief Executive Officer at AON
Thank you, and good morning, everyone. Welcome to our second quarter conference call. I'm joined by Christa Davies, our CFO; and Eric Andersen, our President.
I think, previous quarters we posted a detailed financial presentation on our website. We begin by expressing our deepest appreciation for our colleagues. Their extraordinary dedication delivering results for clients, bringing the best of Aon from across geographies and solution lines is inspiring. And their passion and commitment are reflected in highest ever colleague engagement recorded in our latest report survey.
In the second quarter, our colleagues delivered excellent results demonstrating continued momentum and progress against our key financial metrics. Organic revenue growth is 8% in Q2 and year-to-date. On top of 11% in the prior-year quarter, consistent with our ongoing financial guidance of mid-single digit are greater organic revenue growth. This top-line strength translated into an adjusted operating margin of 26.2% in the quarter, up 40 basis points from last year and adjusted EPS growth of 15%, demonstrating the strength of our Aon United strategy and Aon Business Services platform.
Turning to revenue, commercial risk delivered 7% organic revenue growth, driven by ongoing strong retention and renewals highlighting the strength of our core business and strength in areas of investment like CoverWallet within digital client solutions. In addition, external trends like inflation, continue to be an opportunity for us to help ensure clients are covered for increased exposure.
Reinsurance delivered 9% organic revenue growth in a dynamic renewable market. Our team brought the full capability of our firm's data, analytics and expertise, resulting in strong retention and net new business generation. Health Solutions delivered 11% organic revenue growth, with strong growth in core health and benefits driven by client demand, decreasing healthcare costs and continued growth in advisory work related to regulatory changes, well-being and resilience.
Within Human Capital Solutions, demand remains very high. It's for clients with advice and solutions, especially as they manage ongoing return to work plans, a highly competitive talent market, wage inflation and employee well-being. Finally, Wealth Solutions delivered 3% organic growth, as our team continue to deliver results in core retirement and investment solutions with ongoing additional work helped clients address regulatory changes and impact from recent market conditions, like the opportunity for pension risk transfer. Across wealth and health, external factors are increasing client cost, making it more important than ever for them to efficiently provide comfortable benefits for their employees.
Overall, our strong performance in Q2 and year-to-date reflects the strength of our core business across regions and solution lines. While there is uncertainty around external economic factors, some of the trends that challenge with our economy are positive for our business and create opportunities to help clients. For the full year, we remain confident in our ability to deliver results in each of our three financial commitments. Mid-single digit or greater organic revenue growth, margin improvement and double-digit free cash flow growth.
On the topic of innovation, among many categories of investment, we'd like to highlight two areas where clients are demanding new or better solutions and we are making meaningful progress and serving them. Intellectual property and Climate. On IP, our intellectual property solutions team is delivering a first-of-its-kind solution that enable entrepreneurs to fund IP rich startup growth businesses without giving up ownership using debt that is backed by insured IT assets. Q2 marked an exciting milestone as the team crossed the $1 billion threshold and IP back insurance and hence debt financing.
Let me highlight one recent opportunity where our team supported a high growth technology hardware company. Given the company's business model and growth stage, it had multiple funding avenues available. The company chose this solution to meet its growth capital needs, minimizing equity dilution. The $100 million transaction allowed the company to secure its financing for growth while insurance markets were able to downside risk growth with an innovative application to an intangible asset class.
Going forward, we're making progress to increase the number of lenders and insurance carriers participating in that solution as we build client awareness, accelerate distribution and continue to scale this business. One additional note, as current and evolving economic conditions may compress equity-driven valuation, IP back debt provides a potential new option for start-up growth clients to protect equity ownership and forgo potential down-round funding.
On climate, our turn aim is working on many initiatives. Today we will highlight two. Aon works on Aon and our work supporting renewable energy investment. We'll start with our progress on Aon's journey to zero carbon. In March of 2021, we made an industry-leading commitment to be net zero by 2030, in alignment with Science based targets with Scope 1, 2 and 3 emissions. We're pleased to report that we made great progress so far and reduce our 2021 carbon emissions 12% from our 2019 baseline. As we decarbonize our supply chain, reduced our real estate footprint with smaller, linear space and reduce travel in part with the impact of COVID-19.
Our recent ESG impact report details our commitment and actions on climate, as well as other ESG topics, which are embedded in our overall strategy. Through our clients, this comes down to helping them understand and quantify their climate risk. We prepared to communicate report on this risk and do something about it by building resiliency, positioning in a lower carbon and investing in transition.
Given our track record, underwriting new risks and developing proprietary valuation models, paired with our climate analytics, data and partnerships, we're very well positioned, our clients quantify current and potential future risks, which we can then help them mitigate and transfer. For example, in renewable energy alone, onshore and offshore wind investment exceeds $70 billion today and could grow to nearly $400 billion by 2030. Another rapidly growing addressable market that we serve with meaningful solutions today to ensure the construction and ongoing operation of these facilities.
Similarly, in solar, there is $45 billion of investment today in construction, manufacturing and technology development and we expect this investment to grow to over $100 billion by 2025. Recently, our team facilitated a placement from the world's largest solar farms required in Aon United after the across commercial risk and reinsurance to obtain coverage, despite challenging market conditions. As these renewable energy products projects continue to grow in size, scale and complexity, the need for expertise and innovation and existing technologies will only increase.
Further innovation in areas like carbon capture and storage, hydrogen and other new technologies will require even more innovation to enable the risk financing necessary to make these projects more economically attractive. Our ability to reduce risks for new solutions help to bring in new investment and ultimately helps enable continue boost for decarbonization.
In summary, we delivered a strong quarter, demonstrating continued operating momentum and progress in our key financial metrics. Our Aon United strategy and operating model supported by Aon Business Services places us in a very strong position to support our clients as they face changing economic conditions. In addition, our colleague engagement is very high. As our team delivered on a strategy that enables us to achieve results today, both in the core and in priority growth areas, while also investing in innovative new client solutions like intellectual property and climate.
Finally, our strong performance in Q2 and year-to-date reinforces our commitment to achieving our financial objectives for the year. Now, I'd like to turn the call over to Christa for thoughts on our performance and long-term outlook for continued shareholder value creation. Christa?
