ADP's revenue was up 7% year over year to $5.5 billion and non-GAAP operating margin was up 140 basis points to 25.1% in the fiscal fourth quarter. Management expects fiscal 2027 revenue growth of about 6% and non-GAAP operating margin of about 27.6%.

Why it matters: Momentum across key growth areas like Lyric HCM and global markets, along with pricing strength, drove ADP's solid quarter. Despite macroeconomic uncertainties, labor markets held up well, supporting revenue retention, and are expected to remain broadly stable in 2027. New bookings came in at $2.2 billion, up a healthy 6%, driven by global payroll momentum and growing Lyric HCM adoption. We view Lyric HCM, ADP's new cloud-native platform, as a key near-term bookings driver, though continued gains may be pressured by growing competition. Lyric HCM's success will likely shape ADP's long-term competitive standing in the large midmarket and enterprise space. We view its early momentum favorably but remain on the lookout for competition from Workday, UKG, and other established platforms.

The bottom line: We raise our fair value estimate for narrow-moat ADP to $263 per share from $249 due to slightly higher revenue and profitability estimates. Shares have rallied roughly 40% since the last earnings report, due to software's continued resilience in the artificial intelligence era, and appear fairly valued.

Coming up: Management gave conservative 2027 retention guidance of 91.8%-92%, citing potential increase in out-of-business rates in the down market, though we expect pricing and a largely stable labor market to support the higher end of this range. We continue to view human resources outsourcing services like the professional employer organization business as high-value offerings with solid growth runways. Management expects a near-term slowdown in core PEO revenue due to moderating wage growth, though new bookings should continue to drive growth long-term.

The firm expects interest income of $1.55 billion at the midpoint with an average yield of 3.7%, both higher than our previous estimates. We have updated our estimates accordingly and expect this higher interest income to support greater margin expansion.

Management remains constructive on AI-driven opportunities in the business. While AI offerings remain an indirect revenue and retention driver, management cited AI-driven tools like The Zone as a notable contributor to improving sales efficiency and driving bookings growth

Our fair value estimate is $263 per share, implying a fiscal 2027 adjusted price/earnings ratio of 21 times and an enterprise value/sales ratio of 4 times.

We model a five-year compound annual revenue growth rate of approximately 6%, driven by mid-single-digit growth in employer services and mid- to high-single-digit growth in the PEO business.

Our forecasts reflect growth driven by wallet share expansion across ADP's customer base, tempered by a decelerating pace of new customer additions to reflect growing competition. We anticipate share gain challenges to be most pronounced in the SMB and midmarket segments, though ADP should be able to maintain a solid enterprise presence, enabling the firm to maintain segment revenue retention above 91% throughout our explicit forecast period.

We also expect the firm to benefit from high-margin interest income throughout our explicit forecast period. With the majority of client funds invested in securities with five- to 10-year maturities, we expect ADP's earned interest rates to remain elevated over the next five years.

In PEO, we model mid- to high-single-digit growth in zero-margin benefit pass-throughs alongside low-single-digit growth in the average number of worksite employees, driven by new client additions and stabilizing employment. Excluding benefit pass-throughs, we expect average revenue per worksite employee to grow at a low-single-digit rate, reflecting upside driven by wage inflation and add-on services. We view PEO as a promising opportunity, and looser monetary policy, combined with growing regulatory complexity and the expansion of hybrid work, should drive greater adoption. We also expect ADP to convert small-business customers from its employer services pipeline into its PEO business, deepening wallet share at minimal incremental cost.

We expect non-GAAP operating margin to expand from 27% in fiscal 2026 to approximately 29% in fiscal 2031, driven by operating leverage and high-margin interest income, partially offset by zero-margin benefit pass-throughs. While these pass-throughs structurally suppress reported margins, we view the underlying PEO business as fundamentally healthy, with robust net operating margins averaging 37%-45%. We expect ADP to continue investing in new platform functionalities and AI offerings to remain competitive, which will limit margin gains.

AI is a key consideration for investors and a double-edge sword for ADP. On one hand, automation efficiencies can drive productivity gains and accelerate product innovation. At the same time, AI could intensify competition and damp seat demand as clients achieve the same output with fewer employees, weighing on revenue growth.

We assign ADP a Narrow Morningstar Economic Moat Rating based on switching costs. ADP is a provider of payroll and human resource management solutions. The mission-critical nature of payroll processing and regulatory compliance, along with the financial and legal risks of switching providers, enables ADP to enjoy high switching costs in its businesses. While the spread between ADP's cost of capital and returns on invested capital would nominally suggest a wide moat, the structural risk that AI poses to software and growing competitive intensity in ADP's core markets lowers our confidence in the firm’s ability to retain its current market dominance over the long run.

While market share estimates vary, ADP is a clear leader in its core payroll market, with Paychex as its closest competitor. The broader human capital management landscape includes enterprise platforms such as Workday, Oracle, and SAP, as well as PEO-focused peers like Insperity and TriNet. AI-enabled automations have also supported the rise of a growing cohort of cloud-native upstarts such as Rippling and Gusto targeting the small and midsize business and midmarket segments. Despite this competitive breadth, the industry is characterized by strong retention of 80%-95%, reflecting the providers’ deep entrenchment in clients’ operations. Software in general tends to benefit from high switching costs due to time-consuming and often monetarily expensive processes like product evaluation, system integration, staff training, data migration, and more, across multiple touchpoints in an organization. A client that has absorbed these costs has little incentive to incur them again, and switching providers risks operational disruptions, loss of customer data, and reintegration challenges. ADP's client revenue retention has consistently run around 92%, reflecting the stickiness of its solutions and the significant friction associated with switching providers.

We believe ADP’s employer services segment benefits from high switching costs. This provides a variety of HCM and HR outsourcing (other than PEO) services delivered via platforms tailored to small, midmarket, and enterprise businesses. ADP reports average client tenure in the employer services segment of about 13 years, which reflects the strength of its solutions and the depth of its switching costs. ADP’s offerings effectively create a “living record” of an employee across their hire-to-retire lifecycle. The firm’s value proposition lies in absorbing HR and compliance complexities for its clients to enable significant time and monetary savings. Payroll processing alone involves navigating hundreds of individual variables (tax brackets, benefit elections, filing requirements, regulatory classifications, and more) and entrenches providers like ADP deep into their clients’ day-to-day workflows. Migrating to alternative providers risks errors in regulatory reporting and compensation disbursement, which in turn can trigger significant legal fees, reputational damage, and employee attrition.

ADP is equally dominant in the PEO market. A PEO enters a co-employment relationship with its client, typically a small business, and assumes responsibility for payroll, benefits, and HR compliance on behalf of the client's workforce. By pooling its clients’ employees into a common base, a PEO also enables access to superior benefit premiums and coverage. ADP’s PEO, TotalSource, leads the market with an estimated 20% share, and the top four players collectively account for nearly half of all PEO-covered employees. The broader market remains significantly underpenetrated, with adoption rates estimated to be in the low single digits to midteens. This is largely due to the lack of SMB awareness and a general resistance to outsourcing critical HR functions. However, hybrid work expansion, rising regulatory complexity, and healthcare inflation are increasingly driving adoption, presenting a meaningful growth runway for PEOs. ADP's scale enables favorable benefit-premium negotiations, attractive worker compensation underwriting spreads, and superior risk distribution relative to regional competitors. While the largest PEO peers can broadly match ADP on scale economics, ADP's differentiation lies in the completeness of its offering, as clients benefit from its full payroll infrastructure, compliance expertise, and HCM ecosystem under a single provider.

We believe the PEO segment also benefits from switching costs. Unwinding a PEO relationship involves data migration, dissolving the co-employment structure, transitioning employees to new benefit plans, and managing pending workers' compensation and unemployment claims at meaningful operational and financial costs. Given that TotalSource is built atop Workforce Now, switching PEO providers would likely mean unwinding the underlying HCM platform simultaneously. We believe ADP's average PEO client tenure of six years is healthy (implying roughly 85% revenue retention), considering inherently higher churn rates typical of the SMB customer base, and speaks to the depth of these switching costs.

We believe AI heightens the uncertainty around ADP’s return profile beyond the next decade. ADP’s value proposition lies in application-layer economics without significant domain- or vertical-specific expertise in its workflows, making it vulnerable to competitive erosion. Moreover, large shifts in employment and hiring levels driven by AI and automation efficiencies could impair revenue, given the firm’s exposure to seat-based pricing. While we believe ADP’s massive employment dataset positions the firm well for AI-enabled benchmarking and tools, a clear monetization strategy has yet to be laid out. We do not view these risks as a material threat to ADP's near-term growth, but we have less conviction in the firm’s ability to maintain its market leadership over the long run.

ADP’s rich expertise and depth of offerings lend it enough strength to retain industry trust and grow with its customers as regulatory complexity increases.

International markets remain a largely underpenetrated opportunity for ADP and stand to become a key growth driver as expansion efforts continue.

AI fears have caused a selloff, and ADP is trading at multiyear lows in terms of multiples. If ADP can not only survive but thrive in an AI world, the stock should rerate higher.

Given its sensitivity to employment levels and macroeconomic health, ADP’s growth faces significant downside risk from declines in labor force participation rates and new business formations.

Rapid expansion of the payroll and HCM competitive landscape, alongside converging platform functionalities, could threaten ADP’s pricing power.

AI is emerging as a key threat to seat-based revenue models and can materially increase competition in the industry.
