There are few things more comforting in a corporate earnings presentation than a double-digit growth rate.
Twenty-seven percent sounds particularly nice.
It suggests momentum. Execution. Perhaps even an opportunity for someone in investor relations to use the word “transformational” without getting questioned.
But when financial technology company FIS released its third-quarter results on November 4, that impressive revenue figure came with another number.
3.7%.
Both figures describe revenue growth. Both appear in the company’s own financial disclosures.
And the difference between them is exactly why finance teams should be suspicious of growth rates presented without the accounting context.
The acquisition changed the denominator.
FIS reported approximately $3.45 billion in third-quarter revenue, up 27% from $2.72 billion a year earlier.
On an adjusted basis, the company reported 29% growth.
But on a pro forma basis, which accounts for the acquired Total Issuing Solutions business as though it had been part of FIS during the comparable prior-year period, revenue increased 3.7%.
That’s quite a difference.
The company isn’t necessarily doing anything misleading. It disclosed the different measures and explained the adjustments.
The problem arises when readers treat those growth rates as interchangeable.
Reported growth measures the change between the revenue recognized in the two accounting periods.
Pro forma growth attempts to provide a comparison using a more consistent business perimeter.
When a company completes a major acquisition, those can be very different questions.
A business can report substantial revenue growth because it bought additional revenue. Whether the combined business is generating strong underlying growth requires another calculation.
FIS’s disclosures make that distinction unusually visible.
Its Banking Solutions segment reported 41% revenue growth on a GAAP basis, compared with 3.9% on a pro forma basis.
The acquired business materially changed the size of the operation being measured.
And that creates a challenge for anyone trying to forecast what happens next.
Adjusted EBITDA is growing. So is the need for context.
FIS reported approximately $1.48 billion in adjusted EBITDA for the quarter, an increase of 31% from $1.14 billion a year earlier.
Its adjusted EBITDA margin reached 42.9%, compared with 41.8% in the prior-year period.
That is an improvement of approximately 111 basis points.
On a pro forma basis, however, adjusted EBITDA increased 5.2%, and the comparable adjusted EBITDA margin improved by 94 basis points.
The business still shows positive margin development on that basis. The scale of the earnings growth looks different once the acquired operations are included in the historical comparison.
This matters because acquisition-driven growth and organic operating improvement have different implications.
An acquired business can increase consolidated earnings immediately. It may also bring debt, integration expenses, amortization, and additional capital requirements.
The operating performance of the combined company determines whether the transaction ultimately creates value.
FIS attributed its adjusted margin improvement to factors including the acquired business’s higher-margin profile, favorable revenue mix, and cost savings.
Those drivers deserve separate treatment in a financial model.
A favorable change in business mix is different from reducing the cost of delivering the same services.
An acquisition contribution is different from productivity improvement in the existing business.
If all three are rolled into one margin assumption, the forecast becomes very confident about something it hasn’t actually explained.
There’s $20.8 billion of debt behind the growth story.
At September 30, FIS reported $20.8 billion of outstanding debt.
That number matters because the company has made a deliberate capital-allocation decision.
Following the acquisition of Total Issuing Solutions, FIS temporarily curtailed share repurchases and paused smaller acquisitions to accelerate deleveraging.
Management expects to resume meaningful repurchases after reaching its target gross leverage ratio of approximately 2.8 times.
This is where the financial story moves beyond the income statement.
Acquisitions can expand revenue and adjusted earnings. But financing them changes the balance sheet and the company’s future choices.
Cash used to reduce debt cannot simultaneously fund another acquisition or share repurchase.
FIS generated $862 million of free cash flow in the third quarter, up 8% from $798 million in the prior-year period.
That provides financial capacity, although it does not eliminate the need to prioritize competing uses of cash.
The company also reported returning $248 million to shareholders through dividends and share repurchases during the quarter.
Its capital-allocation policy now emphasizes deleveraging while maintaining dividends.
That distinction is important. The company is prioritizing balance-sheet repair, rather than suspending every form of shareholder distribution.
For finance leaders, this is a useful reminder that capital allocation becomes considerably less theoretical after a major acquisition closes.
The deal may look attractive in the strategic presentation.
The debt schedule still expects to be paid.
A forecast needs to separate the business you bought from the business you grew.
FIS expects full-year 2026 adjusted revenue growth of 28% to 29%.
On a pro forma basis, the company expects revenue growth of 3.1% to 3.6%.
Its adjusted EBITDA outlook calls for growth of 29% to 30%, while pro forma adjusted EBITDA growth is expected to range from 2.9% to 3.6%.
These measures are not contradictory. They use different comparison bases.
But they do tell finance teams why a single growth assumption can be dangerously convenient.
Imagine taking the 27% reported quarterly revenue growth rate and extending it into the next planning period.
Without accounting for the acquisition’s timing, that approach could substantially overstate underlying growth.
The newly acquired revenue does not continue arriving as incremental acquisition-driven growth indefinitely. Once it is included in both comparable periods, the reported growth rate reflects a different mix of drivers.
A credible forecast needs a bridge separating acquired revenue, underlying customer growth, pricing, volume, business mix, and disposals.
The same discipline applies to EBITDA.
Finance should identify which margin improvements come from structural cost changes, which reflect the acquired business, and which depend on integration benefits that have yet to materialize.
Otherwise, the forecast may mistake a change in company size for a change in operating performance.
That can become an expensive misunderstanding when management uses the resulting forecast to approve new spending.
The cash flow guidance deserves its own conversation.
FIS maintained its full-year free cash flow outlook of $2.15 billion to $2.25 billion, representing expected growth of 33% to 39%.
There is an important qualification.
For this outlook, the company defines free cash flow excluding cash transaction taxes related primarily to the Worldpay sale.
That is a legitimate company-defined measure, but it is not identical to unrestricted cash available after every transaction-related obligation.
Anyone using that guidance for liquidity planning or valuation should understand the adjustment.
It is particularly relevant when the same business is managing acquisition-related debt and capital-allocation constraints.
A strong adjusted free cash flow forecast can support confidence in debt repayment capacity.
But finance teams still need to reconcile that measure to actual cash movements, financing obligations, capital expenditures, and transaction-related payments.
Adjusted metrics can help explain a business.
They become less helpful when the adjustments disappear from the conversation.
What the numbers actually say.
FIS’s third-quarter results show a company with higher reported revenue, improving adjusted margins, positive free cash flow growth, and a substantial acquisition that has changed the financial comparisons.
The company is also managing a significant debt balance and prioritizing deleveraging.
There is no need to dismiss the reported growth. The figures are real, and FIS provides the information needed to interpret them.
The question is what that growth represents.
For CFOs and FP&A teams, the distinction affects forecasting, valuation, investment decisions, and management reporting.
A company that grows 27% through a combination of acquisitions and underlying operations requires a different financial model from one generating 27% organic growth.
Both might create shareholder value.
But they carry different assumptions about future revenue, integration costs, financing, and returns on capital.
FIS’s earnings release offers an unusually clear example of why the denominator deserves as much attention as the headline.
Twenty-seven percent may get the attention.
The 3.7% is where the more useful conversation begins.
