Paycom Software, Inc. Reports First Quarter 2015 Financial Results

Record First Quarter Revenue of $55.2 Million, up 49.3% year-over-year

First Quarter GAAP Earnings Per Share of $0.11

First Quarter Non-GAAP Earnings Per Share of $0.12

Paycom Software, Inc. (“Paycom”) (NYSE: PAYC), a leading provider of comprehensive, cloud-based human capital management software delivered as Software-as-a-Service, today announced its financial results for the quarter ended March 31, 2015.

“In the first quarter we continued to see all-time highs in the demand for our single database technology, which drove our best-ever quarterly results as a public company,” said Chad Richison, Paycom founder and CEO. “Primarily our mature sales offices, together with our new sales offices, continue to build momentum by adding new clients. That, coupled with strong demand for our software from businesses and growth in the size of our new business deals, drove revenue growth of nearly 50 percent for the first quarter of 2015. Due to our unique value proposition and people, we believe Paycom is well-positioned for the remainder of 2015 and years to come.”

Financial Highlights for the First Quarter of 2015

Total Revenue of $55.2 million represented a 49.3% increase compared to total revenue of $37.0 million in the same period last year. Revenue growth was driven primarily by the addition of clients in mature sales offices. Revenue also benefited from an increase in the number of tax form filings on behalf of clients. Recurring revenues of $54.4 million increased 49.1% from the comparable prior year period, and comprised 98.4% of total revenues.

GAAP Net Income was $6.0 million, or $0.11 per diluted share, compared to GAAP net income of $1.1 million, or $0.02 per diluted share in the same period last year.

Adjusted EBITDA¹ was $13.6 million, compared to $6.6 million in the same period last year.

Non-GAAP Net Income¹ was $6.7 million, or $0.12 per diluted share, compared to $1.6 million, or $0.03 per diluted share, in the same period last year.

Annualized New Recurring Revenue (“ANRR”) was $20.2 million, up from $12.6 million for the same period last year, representing 60.5% growth from the comparable prior year period.

Cash and Cash Equivalents were $35.7 million as of March 31, 2015.

Total Debt was $26.5 million as of March 31, 2015. This debt consisted solely of debt on the corporate headquarters.

¹ Adjusted EBITDA and non-GAAP net income are non-GAAP financial measures. Please see the discussion below under the heading “Use of Non-GAAP Financial Information” and the reconciliations at the end of this release for additional information concerning these non-GAAP financial measures.

Financial Outlook

Paycom provides the following expected financial guidance for the quarter ending June 30, 2015, and year ending December 31, 2015:

Second Quarter 2015

Total Revenues in the range of $45 million to $46 million.

Adjusted EBITDA in the range of $7.5 million to $8.5 million.

Fiscal Year 2015

Total Revenues in the range of $203 million to $205 million.

Adjusted EBITDA in the range of $35 million to $37 million.

We have not reconciled the Adjusted EBITDA range for the quarter ending June 30, 2015 or the year ending December 31, 2015 to net income because applicable information for future periods, on which this reconciliation is based, is not readily available due to uncertainty regarding, and the potential variability of, depreciation and amortization, interest expense, taxes, stock-based compensation expense and other items. Accordingly, a reconciliation of these Adjusted EBITDA ranges to net income is not available at this time without unreasonable effort.

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 consider and have included certain non-GAAP financial measures in this press release, including Adjusted EBITDA and non-GAAP net income. We use Adjusted EBITDA and non-GAAP net income as supplemental measures to review and assess our performance and for planning purposes. We define: (i) Adjusted EBITDA as net income, plus interest expense, taxes, depreciation and amortization, stock-based compensation expense and certain transaction expenses that are not core to our operations and (ii) non-GAAP net income as net income plus tax adjusted stock-based compensation expense and certain tax adjusted transaction expenses that are not core to our operations. Adjusted EBITDA and non-GAAP net income are metrics that we believe are useful to investors in evaluating our performance and facilitating comparison with other peer companies, many of which use similar non-GAAP financial measures to supplement results under GAAP.

Adjusted EBITDA and non-GAAP net income are not measures of financial performance under GAAP, and should not be considered a substitute for net income, which we consider to be the most directly comparable GAAP measure. Adjusted EBITDA and non-GAAP net income have limitations as analytical tools, and when assessing our operating performance, you should not consider Adjusted EBITDA and non-GAAP net income in isolation, or as a substitute for “Net income” or other Condensed Consolidated Statements of Income data prepared in accordance with GAAP. Adjusted EBITDA and non-GAAP net income may not be comparable to similar titled measures of other companies and other companies may not calculate such measures in the same manner as we do.
