Financial Outlook

Paycom provides the following expected financial guidance for the quarter ending March 31, 2022 and the year ending December 31, 2022:

Quarter Ending March 31, 2022:

Total Revenues in the range of $342 million to $344 million.

Adjusted EBITDA in the range of $161 million to $163 million.

Year Ending December 31, 2022:

Total Revenues in the range of $1.314 billion to $1.316 billion.

Adjusted EBITDA in the range of $524 million to $526 million.

We have not reconciled the forward-looking adjusted EBITDA ranges presented above and discussed on the teleconference call to net income, nor the forward-looking adjusted EBITDA margins and forward-looking non-GAAP effective income tax rate discussed on the teleconference call to comparable GAAP measures, because applicable information for future periods, on which these reconciliations would be based, are not readily available due to uncertainty regarding, and the potential variability of, depreciation and amortization, interest expense, taxes, non-cash stock-based compensation expense, change in fair value of our interest rate swap and other items. Further, we have not reconciled the forward-looking adjusted gross margin range discussed on the teleconference call to GAAP gross margin because applicable information for future periods, on which this reconciliation would be based, is not readily available due to uncertainty regarding, and the potential variability of, cost of revenues, including non-cash stock-based compensation expense. Accordingly, reconciliations of the forward-looking adjusted EBITDA ranges to net income, the forward-looking adjusted EBITDA margins to net income margin, the forward-looking adjusted gross margin range to gross margin and the forward-looking non-GAAP effective income tax rate to the GAAP effective income tax rate are not available at this time without unreasonable effort. During the teleconference call, we also refer to a forward-looking estimate of our implied revenue growth plus adjusted EBITDA margin, or the "Rule of 65." Because we are unable to reconcile forward-looking adjusted EBITDA margin to net income margin without unreasonable effort, we are unable to reconcile the "Rule of 65" to a comparable GAAP measure without unreasonable effort.

Impact of the COVID-19 Pandemic

During the fourth quarter of 2021, the majority of our employees returned to our offices. We may take further actions that alter our business operations as may be required by federal, state or local authorities or that we determine are in the best interests of our employees and clients. Business continuity and safety has and will continue to guide our workplace arrangements. Although we currently have some insight with respect to the effects of the COVID-19 pandemic to date, it is not possible at this time to estimate the full impact that the pandemic could continue to have on our business and results of operations.

The COVID-19 pandemic has resulted in, and may continue to result in, headcount fluctuations across our client base. Because we charge our clients on a per-employee basis for certain services we provide, headcount fluctuations at our clients impacts our recurring revenue. The negative effects on our client revenue of lower headcount resulting from the pandemic were more than offset by headcount additions from new clients added since the beginning of the pandemic and modestly improved headcount levels among our pre-pandemic client base beginning in the second quarter of 2021. We expect that our recurring revenue in future periods will continue to be impacted by such headcount fluctuations.
Despite growth in the number of clients in our base and growth in our average funds held for clients balance, significantly lower average interest rates during 2021 as compared to 2020 had a negative effect on interest earned on funds held for clients and, consequently, recurring revenue growth in the three and twelve months ended December 31, 2021.
Our solution allows clients to seamlessly manage and communicate with their remote workforces. In a work-from-home environment, our clients have recognized the benefits of our focus on employee usage, as well as the strengths and advantages of our single database solution.
While our sales force continues to conduct meetings with current and prospective clients virtually, as prospective clients begin to take meetings in-person, we expect our sales process to include a combination of virtual and in-person meetings.

Use of Non-GAAP Financial Information

To supplement our financial information presented in accordance with generally accepted accounting principles in the United States ("GAAP"), we present certain non-GAAP financial measures in this press release and on the related teleconference call, including adjusted EBITDA, non-GAAP net income, adjusted gross profit, adjusted gross margin, adjusted sales and marketing expenses, adjusted total administrative expenses, adjusted research and development expenses, adjusted total research and development costs, adjusted EBITDA margin and "Rule of 65". Management uses these non-GAAP financial measures as supplemental measures to review and assess the performance of our core business operations and for planning purposes. We define (i) adjusted EBITDA as net income plus interest expense, taxes, depreciation and amortization, non-cash stock-based compensation expense, certain transaction expenses that are not core to our operations (if any) and the change in fair value of our interest rate swap, (ii) non-GAAP net income as net income plus non-cash stock-based compensation expense, certain transaction expenses that are not core to our operations (if any) and the change in fair value of our interest rate swap, all of which are adjusted for the effect of income taxes, (iii) adjusted gross profit as gross profit plus applicable non-cash stock-based compensation expense, (iv) adjusted gross margin as gross profit plus applicable non-cash stock-based compensation expense, divided by total revenues, (v) each adjusted expense item as the GAAP expense amount less applicable non-cash stock-based compensation expense, (vi) adjusted total research and development costs as total research and development costs (including the capitalized portion) less applicable non-cash stock-based compensation (including the capitalized portion), (vii) adjusted EBITDA margin as adjusted EBITDA (calculated as described in clause (i)) divided by total revenues, (viii) "Rule of 65" as revenue growth (expressed as a percentage) plus adjusted EBITDA margin (calculated as described in clause (vii)) and (ix) non-GAAP effective income tax rate as the provision for income taxes plus the income tax effect on non-GAAP adjustments divided by non-GAAP net income (calculated as described in clause (ii)) plus the provision for income taxes and the income tax effect on non-GAAP adjustments. The non-GAAP financial measures presented in this press release and discussed on the related teleconference call provide investors with greater transparency to the information used by management in its financial and operational decision-making. We believe these metrics are useful to investors because they facilitate comparisons of our core business operations across periods on a consistent basis, as well as comparisons with the results of peer companies, many of which use similar non-GAAP financial measures to supplement results under GAAP. In addition, adjusted EBITDA is a measure that provides useful information to management about the amount of cash available for reinvestment in our business, repurchasing common stock and other purposes. Management believes that the non-GAAP measures presented in this press release and discussed on the related teleconference call, when viewed in combination with our results prepared in accordance with GAAP, provide a more complete understanding of the factors and trends affecting our business and performance.

The non-GAAP financial measures presented in this press release and discussed on the related teleconference call are not measures of financial performance under GAAP and should not be considered a substitute for net income, gross profit, gross margin, research and development expenses, sales and marketing expenses, administrative expenses and total research and development costs. Non-GAAP financial measures have limitations as analytical tools, and when assessing our operating performance, you should not consider these non-GAAP financial measures in isolation, or as a substitute for the consolidated statements of income data prepared in accordance with GAAP. The non-GAAP financial measures that we present may not be comparable to similarly titled measures of other companies and other companies may not calculate such measures in the same manner as we do.
