Automatic Data Processing Q1 FY2027: EPS +14% to $2.83; client-fund interest drove ~half the profit gain

Automatic Data Processing (ADP) runs payroll, HR and benefits administration for more than 1.1 million employers. Its fiscal year ends June 30, so fiscal Q1 2027 covers July through September 2026. Revenue rose 6.1% to $5,490.7 million (6% on an organic constant currency basis, meaning excluding acquisitions and currency swings), net earnings rose 11.1% to $1,125.2 million and diluted EPS rose 13.7% to $2.83. Management raised its full-year revenue and adjusted EPS outlook.

Almost half of the profit increase came from one source: interest ADP earns on payroll money it holds for clients before paying it out. Pre-tax earnings rose $147.4 million, and $69.2 million of that was the net gain from this "client funds" investing. Excluding it, pre-tax earnings grew about 7.5%. That is still solid, but slower than the headline.

Key figures

ADP has no "operating income" line. The pre-tax margin above (earnings before income taxes divided by revenue) is the margin figure in the metrics strip. Adjusted EBIT is ADP's own non-GAAP measure. It adds back taxes and interest unrelated to the client-funds strategy, plus a $2.9 million gain on venture investments.

The two businesses

Employer Services is ADP's core payroll, HR and outsourcing business. Revenue rose 5.6% to $3,685.4 million (6% on both a reported and an organic constant currency basis). Segment earnings rose 9.3% to $1,343.5 million, and the segment margin widened 130 basis points to 36.5%. A basis point is one-hundredth of a percentage point. Pays per control is ADP's same-store measure of how many employees appear on existing clients' payrolls. It rose 2%, compared with 0% a year earlier. That gives a modest boost because ADP charges partly per employee processed.

PEO Services is ADP TotalSource. ADP becomes the co-employer of a client's staff (called "worksite employees") and handles their benefits, workers' compensation and payroll taxes. Revenue rose 7.1% to $1,808.1 million, but most of the increase passed through at cost. Zero-margin benefits pass-throughs are health-insurance and similar costs that ADP bills to clients and pays out without a markup. They rose $97.6 million to $1,228.6 million, accounting for about 81% of the $120.6 million PEO revenue increase. Excluding them, PEO revenue grew 4%. The average number of worksite employees rose 2% to about 771,000. Segment earnings rose 7.1% to $234.4 million, and the margin was flat at 13.0%. That is an improvement on fiscal 2026, when PEO's margin fell 110 basis points.

Takeaway: ADP's 14% EPS growth rests on three supports of roughly decreasing size: higher interest on client cash (about half the pre-tax profit gain), modest operating leverage in Employer Services (revenue excluding that interest +5.6%, with expenses growing more slowly), and a 2.2% smaller share count. The part that depends least on interest rates, the core fee business, is growing in the mid-single digits. The bigger profit swings come from rates and buybacks.

The client-funds "float"

Between collecting payroll money from employers and paying it to employees and tax authorities, ADP invests the cash. Average client balances rose 6% to $36.9 billion, and the average yield rose 30 basis points to 3.6%. Together they lifted interest on funds held for clients by $42.5 million to $329.3 million. ADP also borrows short-term so it can keep these investments at longer maturities, and it invests corporate cash alongside them ("corporate extended"). Income on that corporate portfolio rose $27.4 million to $106.1 million. The cost of the short-term borrowing was almost unchanged at $102.5 million, because the rate paid fell to 3.7% from 4.4% even as the amount borrowed rose 19%. The net contribution from the whole strategy rose 26% to $332.9 million.

This revenue carries almost no cost, which is why it moves margins so much. It also means some of this quarter's margin gain came from interest rates rather than from running the business more efficiently.

What the headline numbers hide

• GAAP vs adjusted: the two are almost identical ($2.83 GAAP, $2.82 adjusted). The only adjustment this quarter is a $2.9 million gain on ADP Ventures investments ($0.01 a share). The prior-year quarter had no adjustments, so the year-over-year comparison is not distorted by one-offs.
• Where the profit growth came from: pre-tax earnings rose $147.4 million. Of that, $69.2 million was the higher net contribution from client-funds investing. Without it, pre-tax earnings would have risen about 7.5% instead of 11.3%. The release does not explain the margin expansion beyond that. Research and development spending was flat at $251.3 million, and operating expenses rose 5.0%, slower than revenue. This follows the $91.1 million severance-led "business alignment program" charge taken in fiscal 2026's fourth quarter. The release does not link the two, but lower headcount costs would show up in exactly these lines.
• Buybacks: ADP repurchased $758.8 million of stock, more than double the $366.0 million a year earlier, and diluted shares fell 2.2%. That is why EPS grew 13.7% while net earnings grew 11.1%. Buybacks contributed about 2.5 points of EPS growth.
• Tax: the effective tax rate was 22.7%, slightly higher than 22.5% a year earlier, so tax did not help EPS.
• Cash conversion: operating cash flow of $651.0 million was only 58% of net earnings. This is a seasonal pattern rather than a new problem. The year-ago quarter was 63% ($642.3 million on $1,013.0 million). Accrued payroll and payroll-related expenses fell by $460.2 million from June 30, and the cash-flow line for lower accrued expenses ($389.4 million) was about the same size as a year ago ($376.2 million). Cash paid for income taxes was also higher, at $187.2 million versus $73.8 million. Receivables were flat against June 30 ($3,524.0 million vs $3,521.1 million).
• Capital returned exceeds cash generated this quarter: ADP paid $677.0 million in dividends and $758.8 million in buybacks, $1.44 billion in total against $651.0 million of operating cash flow. Corporate cash fell to $3,277.0 million from $4,230.1 million. Over a full year, ADP's cash flow covers these payouts (fiscal 2026 operating cash flow was $5.4 billion). But the quarter's buyback pace, about $3 billion a year if annualized, is faster than last year's $2.1 billion.

On balance this is a clean quarter. GAAP and adjusted EPS match, there are no material one-offs in either year, and most EPS growth came from higher pre-tax profit. Investors should still recognize that about half of that profit gain depends on interest rates.

Did last time's read hold up?

Our fiscal 2026 annual report flagged three things to watch:

• Whether client hiring would stay near zero. It did not: pays per control rose 2%, against guidance of 0–1%.
• Whether the severance program would lower the cost base. The early evidence is consistent with it: R&D was flat, and operating expenses grew more slowly than revenue.
• Whether the client-funds line was the most rate-exposed part of the guidance. It was the line that moved most, but upward: ADP raised its client funds interest outlook by $50 million at the midpoint.

The read held up, and the first quarter came in better than that read expected.

Outlook: raised, mostly through interest income

ADP's updated fiscal 2027 guidance (compared with the July 29, 2026 outlook):

The GAAP EPS guide (12–14%) is higher than the adjusted one (10–12%) because fiscal 2026's $91.1 million business alignment charge and $18.0 million legal settlement will not recur. The release does not give a Q1 figure for new business bookings or retention, and the full-year targets for both are unchanged.

Our read: the raise is mostly the float. The client-funds strategy is now expected to contribute $1,590–1,610 million, about $45 million more pre-tax at the midpoint than in July. After roughly 23% tax and on about 397 million shares, that is about $0.09 a share, or about 0.8 points of growth on fiscal 2026's $11.12 adjusted EPS. That accounts for most of the 1-point raise to the EPS range. The margin target did not move, so the stronger first-quarter margin (+130 bps) is not yet assumed to continue at that pace. The two things to watch next quarter are the same as before: whether pays per control stays above 1% (a hiring slowdown would show up there first), and whether short-term rates fall faster than the October 27 forward curves ADP used, which would cut into the client-funds line that is carrying the raise.

The full 10-Q, with management's discussion of the quarter's results, had not been filed when this report was written, so the segment margin drivers above rely on the release's tables rather than ADP's own explanation.
