Principal Financial Group generated $13.1 billion in total revenues for the fiscal year 2024, operating as the second-largest provider of small business retirement plans in the United States by participant count and a dominant force in the group benefits and asset management sectors, managing over $650 billion in total assets and maintaining a highly profitable operating margin of 10.7%. Under CEO Jim Wehlever, the 145-year-old company is executing a massive digital transformation, targeting 35% of new small business premium through embedded digital workplace channels by 2027 to shift its distribution model and improve customer acquisition costs.

How Does Principal Financial Group Make Money?
Principal makes money through a highly complex, multi-layered business model that relies on three primary engines: the collection of insurance premiums, the management of spread margins on interest-sensitive products, and the generation of net investment income from a massive $650 billion general and separate account asset base. The company collects billions in upfront premiums, holds the cash for decades before paying out claims or annuity benefits, and invests that massive pool of capital in a highly diversified portfolio of corporate bonds, commercial mortgages, and structured securities, generating over $1.5 billion in annual net investment income that effectively subsidizes the cost of acquiring new customers. The company's operations are divided into three distinct reporting segments: Retirement and Income Solutions, which accounts for approximately 40% of total revenues; Asset Management, which accounts for approximately 31%; and Benefits and Protection, which accounts for the remaining 29%. The profitability of the pension risk transfer (PRT) business is driven by the spread margin, which is the difference between the yield earned on the underlying investment portfolio and the crediting rate paid to the policyholder. In FY2024, as interest rates remained elevated, Principal was able to invest new premiums and reinvested maturities into high-yielding corporate bonds and commercial mortgages, earning an average yield of 5.4%, while crediting a rate of 3.9% to policyholders, generating a highly profitable 150 basis point spread margin.
Who Founded Principal Financial Group and When?
Principal traces its origins back to 1879, when it was founded in Des Moines, Iowa, as the Principal Mutual Life Insurance Company by Edward H. Rollins and a syndicate of local investors who recognized the massive, unpriced risk of occupational mortality in the rapidly industrializing American Midwest. Rollins's defining moment came in the early days of the company, when he personally traveled to the industrial centers of Chicago, Omaha, and Minneapolis, convincing factory workers and farmers to purchase $5,000 whole life policies that promised a modest death benefit and a guaranteed cash value accumulation, a revolutionary concept for workers who lived paycheck to paycheck. Rollins's philosophy was that life insurance was not a luxury for the wealthy, but a fundamental necessity for the working class, and he established a corporate culture of aggressive, grassroots distribution that would define the company for the next century. For its first seven decades, the company's primary business was selling whole life policies to factory workers and industrial laborers, only executing its massive pivot to a complex, diversified financial services firm in the 1970s and 1990s through the launch of variable products and its transformative 1998 initial public offering.
What Is Principal Financial Group's Competitive Advantage?
Principal's single largest competitive advantage is its absolute dominance in the small business retirement market, combined with a highly sophisticated, proprietary underwriting algorithm that processes over 4 million policy transactions annually. The small business retirement business is a highly specialized, relationship-driven niche that requires a deep, forensic underwriting of an employer's specific industry risks, occupational hazards, and geographic concentrations, acting as a massive barrier to entry for any new competitor. Principal administers the 401(k) plans of over 1.2 million small and medium-sized enterprises (SMEs), a position that generates highly predictable, low-volatility fee income and creates massive switching costs for the mid-sized and large employers that rely on these benefits to attract and retain talent. This dominance in small business retirement is inextricably linked to Principal's broader distribution moat: the massive network of 15,000 third-party administrators (TPAs) and financial advisors who place these group policies also control the flow of individual life and retirement business, creating a highly efficient, low-cost acquisition channel for Principal's annuity and life insurance products.
How Has Principal Financial Group's Revenue Grown Over Time?
Principal's revenue has grown at a steady, consistent pace over the past five years, generating $13.1 billion in FY2024, up from $11.5 billion in FY2020, as the company successfully navigated the dual headwinds of the pandemic and the most volatile interest rate environment in four decades. The composition of that revenue is highly diversified: the Retirement and Income Solutions segment generated $5.2 billion in revenues in FY2024, representing an 8% year-over-year increase driven by strong sales of pension risk transfer (PRT) buyouts and the higher yields earned on the general account assets. The Asset Management segment generated $4.1 billion in revenues, a 6% increase that reflected a deliberate strategy to grow its multi-asset, outcome-oriented funds while aggressively pruning unprofitable, high-capital international equity mandates. The Benefits and Protection segment contributed $3.8 billion in revenues, a 5% increase fueled by the explosive growth of the voluntary benefits market, where employers are increasingly shifting the cost of healthcare and disability coverage to employees through workplace-sponsored supplemental insurance products. This shift is critical because the net investment income on the $650 billion portfolio generated over $1.5 billion in FY2024, accounting for nearly 40% of the company's total pre-tax income, a structural advantage that allows Principal to remain profitable even in years where mortality or morbidity experience is adverse.
Principal Financial Group Business Model Explained
Principal operates a highly efficient small business distribution model for its retirement and group protection business, writing the vast majority of its 401(k) and disability policies through a network of 15,000 third-party administrators (TPAs) and financial advisors, a strategic choice that keeps customer acquisition costs remarkably low while creating immense operational stickiness. Principal has invested hundreds of millions of dollars into proprietary quoting and policy management software that integrates directly into the daily workflow of these TPAs and the HR departments of its employer clients. Once an employer's staff is trained on Principal's interface, and their employee census data is housed within the Principal ecosystem, the friction of switching to a competitor like Fidelity or Charles Schwab is incredibly high. The unit economics of this model are highly favorable: the marginal cost of processing an additional small business policy is near zero, while the marginal cost of a direct-to-consumer acquisition requires massive marketing spend. This is why the company is aggressively pushing its digital workplace platform, partnering with industry-specific software providers like Workday and ADP to embed its quoting engines directly into the workflow of HR professionals. The exact margin structure shows gross underwriting margins sitting at roughly 10.7%, but the massive net investment income from the $650 billion portfolio amplifies this to a highly profitable net income of $1.4 billion in FY2024.
Principal Financial Group Key Acquisitions
Principal has used targeted, massive acquisitions to accelerate its growth and defend its market share against competitors. In 2012, the company completed the transformative $1.2 billion acquisition of AHM Capital Management's mortgage servicing rights, instantly scaling its alternative asset management capabilities and establishing its dominance in the private credit space. This acquisition provided the massive scale required to compete with BlackRock and Apollo in the alternative asset management market. In 2015, Principal acquired RBC Insurance's U.S. life and annuity business for $900 million to aggressively expand its retirement and income solutions distribution network, acquiring a massive book of high-quality, capital-efficient products and a highly productive independent agent force. The acquisition allowed Principal to integrate RBC's highly profitable fixed index annuity and universal life book into its own ecosystem, instantly scaling its retail distribution network and increasing the company's total assets under management by over $40 billion. Finally, in 2010, the company acquired StanCorp Financial Group for $600 million to expand its presence in the group protection and employee benefits market, acquiring a massive book of group disability and dental assets and a highly productive team of workplace benefits consultants, a strategic pivot that established Principal as a dominant force in the mid-market group protection channel.
What Are the Biggest Risks Facing Principal Financial Group?
The single biggest risk facing Principal is the rapid, widespread adoption of GLP-1 receptor agonist weight loss drugs, such as Ozempic, Wegovy, and Mounjaro, which are fundamentally rewriting the long-term mortality and morbidity expectations for the American population. If this trend materializes at scale, Principal will face a massive adverse selection problem in its life insurance book, as policyholders who are taking these drugs will live significantly longer than the actuarial tables predict, forcing the company to pay out annuity benefits for a much longer period and delaying the collection of life insurance death benefits, a dynamic that severely compresses the internal rate of return on the underlying portfolio. Additionally, the company faces the structural challenge of tightening regulatory capital requirements from the NAIC, which is continuously updating the stochastic modeling requirements for insurers offering complex guaranteed products, forcing Principal to hold significantly more statutory capital against its pension risk transfer (PRT) and annuity books, a dynamic that compresses return on equity and limits the company's ability to deploy capital into higher-yielding, riskier assets.
Bottom Line
Principal is a legacy giant in the midst of a critical digital transformation, generating $13.1 billion in annual revenue while aggressively shifting its distribution model toward embedded digital workplace channels for small business retirement and group protection. The company's absolute dominance in the small business retirement market remains an insurmountable moat in the workplace benefits space, but its long-term survival depends on its ability to navigate the GLP-1 drug revolution and defend its market share against private equity-backed competitors. Under CEO Jim Wehlever, Principal has achieved a robust 390% Risk-Based Capital ratio and generated over $1.5 billion in net investment income, proving that the 145-year-old company can still adapt to the digital age while maintaining the extreme capital conservatism that has defined it since 1879.
