S&P Global Inc. (SPGI)

S&P Global Inc. (NYSE: SPGI) is one of the world’s largest providers of credit ratings, financial data, analytics, and market infrastructure. It is best known for the Standard & Poor’s credit-rating agency, but the company has evolved into a diversified information platform that serves banks, investors, corporations, and exchanges across the globe. The business is built on data, research, and decision tools that financial professionals depend on to evaluate risk, find investment opportunities, and trade. Most of S&P Global’s revenue comes from subscriptions and licensing fees — recurring, high-margin income that is relatively insensitive to market cycles.

The company is the product of multiple mergers and acquisitions dating back to a 1941 founding and consolidation through the 1990s and 2000s. Today it operates four main segments: Ratings (credit analysis and ratings), Market Intelligence (market data, indexes, and research), Platts (energy and commodities data and price assessment), and Divisions focused on trading and risk analytics.

Ratings — the iconic core

The Ratings segment is the oldest and most recognized piece of S&P Global. Standard & Poor’s has issued credit ratings on bonds, bank debt, and corporate bonds since the early twentieth century, and the practice of credit rating became a professional discipline and a regulatory fixture in the latter half of the twentieth century. Banks, insurance companies, pension funds, and individual investors all use ratings as a primary input to credit decisions.

The rating system itself is simple: ratings range from AAA (safest) to D (in default), and provide a shorthand assessment of the probability that a borrower will pay back what it owes. When a corporation borrows, when a government issues debt, or when a bond is issued, the issuer typically seeks a rating from one of the Big Three rating agencies — Standard & Poor’s, Moody’s, and Fitch. The rating agency analyzes the borrower’s financial condition, competitive position, and likelihood of default, then assigns a rating. The rating is then published, and the market uses it (along with other information) to price the debt.

S&P Global earns revenue when issuers solicit a rating (issuer-paid model) and through subscriptions from investors and banks who want to access ratings data and analytics. The issuer-pays model is controversial — rating agencies have financial incentive to rate issuers favorably, which creates potential conflicts of interest — but it remains the dominant revenue model in the industry. Regulatory oversight of rating agencies exists but is limited; the U.S. Securities and Exchange Commission oversees Nationally Recognized Statistical Rating Organizations (NRSROs), but the actual rating process is not heavily regulated.

Ratings is a high-margin business once established. The largest costs are analyst salaries and technology infrastructure; the marginal cost of distributing a rating is nearly zero. The segment benefits from relative stability in credit markets: even when issuance volumes fall, the universe of existing rated debt must be monitored and re-evaluated, so there is baseline recurring demand for rating services.

Market Intelligence — indexes, data, and research

The Market Intelligence segment is built around FactSet (a portfolio company acquisition), Market Data Group, and other brands that provide financial data, indexes, and analytics to institutional investors and financial advisors. This segment includes:

Index businesses — S&P Global constructs and maintains numerous stock indices, including the S&P 500, the S&P MidCap 400, and many others. These indices are used as benchmarks for portfolios, as the basis for exchange-traded funds (which track the index), and as reference points for derivatives. Whenever an investor buys an S&P 500 index fund, they are paying a licensing fee to S&P Global for the use of the index. Passive investing’s rise over the past two decades has been a material tailwind for index providers.

Market data — Bloomberg terminals and other professional data feeds are the traditional source of prices, quotes, and reference data for traders and portfolio managers. S&P Global competes in this space, offering data through multiple platforms and APIs.

Research and analytics — Corporate credit analysis, sector research, and company-specific financial analysis sold to institutional clients. Some of this is proprietary; some comes from partnerships and acquisitions.

This segment is also largely subscription-based, with recurring revenue and high margins once clients are acquired. Institutional investors and financial advisors depend on these tools for daily operations; switching costs are high (retraining staff, integrating new systems), so retention is strong.

Platts — energy data and price assessment

Platts, acquired in 2021, is a long-standing provider of energy and commodities market data and price assessments. The segment covers crude oil, natural gas, coal, power, metals, and agriculture. Platts operates a price-assessment business: it surveys trading activity and published trades in physical and derivatives markets, synthesizes that information, and publishes daily price indices that market participants use as reference points for their own trading and contracting.

Platts is also subscription-based, serving traders, hedgers, producers, and refiners who need reliable price signals. The business is somewhat more cyclical than Ratings or Market Intelligence — in dormant commodity markets, pricing activity drops and subscription revenue can suffer — but it is still a durable information business with recurring revenue.

The addition of Platts expanded S&P Global’s footprint in commodities and energy, markets where financial infrastructure and data are equally critical to equities and bonds.

Recurring revenue and the moat

Across all segments, S&P Global’s business model is built on recurring, subscription-based revenue. A bank or investment fund subscribes to ratings data or market data; they renew annually, often automatically, until they choose to cancel. Churn rates are low because switching costs — retraining staff, integrating new systems, potentially losing access to proprietary indices — are high. Once a customer is acquired, they tend to stay.

This recurring-revenue model produces predictable cash flow, high operating leverage (incremental subscriptions add margin), and valuations that reward growth or stability more generously than transaction-based or transient revenue models. S&P Global’s profit margins are well above average for financial services.

Regulatory risks and dependencies

S&P Global’s Ratings segment is highly regulated. The SEC oversees NRSO rating agencies, examining whether they follow their stated methodologies, whether they manage conflicts of interest, and whether they have appropriate controls. The rating industry faced intense scrutiny after the 2008 financial crisis, when major rating agencies failed to foresee the wave of mortgage-backed-security defaults, resulting in downgrades and losses for investors who relied on inflated ratings. Regulatory pressure has increased since, and rating agencies must now publish more detailed methodologies, audit controls, and disclosures.

Regulatory pressure can constrain the Ratings segment. A rule requiring that ratings be more transparent, or that conflicts of interest be managed more carefully, raises costs. More fundamentally, any proposal to change the issuer-pays model (e.g., towards an investor-pays model) would materially alter the business. Regulators have discussed such changes periodically, though no major overhaul has occurred.

The index business is less regulated but faces different risks. Regulatory scrutiny of passive investing and index methodology is increasing. Proposals to require index providers to rotate their holdings more frequently, or to diversify eligibility rules, would change the business. So far, these remain proposals rather than law, but they represent a background risk.

Competition and market position

S&P Global is the largest rating agency globally by volume and reputation. Moody’s is a close peer, and Fitch is smaller but established. The Big Three have consolidated the market to the point that it is nearly impossible for a new entrant to build credibility (regulators recognize only these three as NRSO agencies for U.S. purposes). This creates a durable, three-firm oligopoly in ratings.

In market data and indices, there is more competition. Bloomberg and Refinitiv (owned by LSEG) are major competitors. But network effects (more assets in an index, more pricing in a data service) create advantages for scale. S&P Global’s indexes and data offerings are deeply embedded in institutional portfolios.

Capital allocation and returns to shareholders

S&P Global is a cash-generative business, and it returns capital to shareholders through dividends and share repurchases. The company has increased its dividend annually for decades. Buybacks have also been a significant component of shareholder return, reducing share count and supporting earnings-per-share growth.

The company has also pursued acquisitions to expand its portfolio, most notably Platts for approximately 4 billion dollars in 2021. That acquisition reflected the strategic decision to broaden beyond equities and fixed-income markets into commodities and energy data.

How to research S&P Global

Start with the annual 10-K filing (SEC CIK 0000064040), which breaks down revenue and profit by segment and discusses competitive dynamics, regulatory risk, and management strategy. Quarterly earnings calls provide commentary on subscription renewal rates, client wins and losses, and pricing power.

Key metrics: revenue growth by segment (which parts of the business are accelerating?), net dollar retention (are existing customers buying more or less?), operating margin (is the business maintaining or expanding profitability?), and capital allocation (how much is being returned to shareholders versus reinvested?). Watch regulatory developments carefully, particularly any discussion of changing the rating-agency model or increasing index regulation.

S&P Global is a financial-infrastructure play — it provides data and decision tools that the financial system depends on. Growth comes from market growth, from new types of data and analytics, and from raising prices as customers become more dependent. The competitive moat is strong, particularly in ratings and indexes, but regulatory risk is perennial. The investment case hinges on the durability of recurring revenue, the ability to raise prices, and the company’s skill at managing regulatory and competitive threats.
