Insperity Announces Fourth Quarter and Full Year Results

• Q4 adjusted EPS of $0.24 on 4.6% revenue growth

• Q4 adjacent business gross profit contribution increases 36% year over year

• Q4 average number of trained Business Performance Advisors up 27% over 2012

HOUSTON – Feb. 10, 2014 – Insperity, Inc. (NYSE: NSP), a leading provider of human resources and business performance solutions for America’s best businesses, today reported results for the fourth quarter and year ended Dec. 31, 2013. For the fourth quarter, the company reported adjusted net income of $6.2 million and adjusted diluted earnings per share of $0.24. Adjusted net income excludes an after tax non-cash impairment charge of $2.9 million, or $0.11 per share, associated with a write-down of goodwill and intangibles related to a 2010 acquisition, partially offset by a $2.0 million, or $0.08 per share, tax credit. Reported fourth quarter net income and earnings per share were $5.3 million and $0.21, respectively.

For the year ended Dec. 31, 2013, the company had adjusted diluted earnings per share of $1.39. Adjusted results exclude $0.22 per share related to non-cash impairments, partially offset by an $0.08 per share tax credit. Reported 2013 net income was $32.0 million, or $1.25 per share.

“We are pleased with the increase in Business Performance Advisors and the outlook for growth acceleration in 2014 and beyond,” said Paul J. Sarvadi, Insperity chairman and chief executive officer. “We are well-positioned to capitalize on the opportunities provided by our adjacent business technology offerings and from the small business market disruption we expect over the next several years as a result of health care reform.”

Fourth Quarter Results

Revenues for the fourth quarter of 2013 increased 4.6% over the fourth quarter of 2012 due to a 1.1% increase in the average number of worksite employees paid per month and a 3.5% increase in revenues per worksite employee per month.

Gross profit decreased 3.8% compared to the fourth quarter of 2012 to $90.0 million. This decline was primarily the result of a higher deficit in the benefits cost center, which was partially offset by a higher gross profit contribution from our adjacent businesses.

Operating expenses increased 7.1% to $83.1 million compared to the fourth quarter of 2012. This increase included costs associated with the hiring of additional Business Performance Advisors, the number of which was up 27.2% over 2012. On a per worksite employee per month basis, operating expenses increased 6.0% to $212 in 2013 from $200 in 2012.

Full Year Results

Revenues in 2013 were $2.3 billion, an increase of 4.5% over 2012. Gross profit for the year ended Dec. 31, 2013, increased 2.9% to $393.3 million. The average gross profit per worksite employee per month increased $4, or 1.6%, to $257 in 2013 from $253 in 2012. Benefits costs per covered employee increased 4.7% over 2012. Additionally, gross profit contribution from adjacent businesses increased 26.2% over 2012.

Operating expenses increased 7.1% in 2013 to $337.0 million. On a per worksite employee per month basis, operating expenses increased 5.8% to $220 in 2013 from $208 in 2012. This increase included costs associated with the hiring of additional Business Performance Advisors, the implementation of the company’s health care reform strategy, and technology and personnel investments made in our Workforce Optimization^® solution and adjacent businesses.

Reported operating income for the year ended Dec. 31, 2013, was $56.2 million.

Adjusted EBITDA totaled $92.3 million in 2013. These results exclude non-cash impairment charges of $6.0 million and stock-based compensation of $11.1 million. Cash outlays in 2013 included the repurchase of 596,834 shares at a cost of $17.2 million, dividends of $17.4 million, and capital expenditures of $11.6 million. Working capital at Dec. 31, 2013, was $128.6 million.

“With our strong balance sheet and cash flow, we are in a position to make investments in product development and growth, while continuing to provide a return to stockholders in the form of dividends and stock repurchases,” said Douglas S. Sharp, senior vice-president of finance, chief financial officer and treasurer.

Generally, these statements relate to business plans or strategies, projected or anticipated benefits or other consequences of such plans or strategies, or projections involving anticipated revenues, earnings, unit growth, profit per worksite employee, pricing, operating expenses or other aspects of operating results. We base the forward-looking statements on our expectations, estimates and projections at the time such statements are made.

Among the factors that could cause actual results to differ materially are: (i) adverse economic conditions; (ii) regulatory and tax developments and possible adverse application of various federal, state and local regulations; (iii) the ability to secure competitive replacement contracts for health insurance and workers’ compensation contracts at expiration of current contracts; (iv) increases in health insurance costs and workers’ compensation rates and underlying claims trends, health care reform, financial solvency of workers’ compensation carriers, other insurers or financial institutions, state unemployment tax rates, liabilities for employee and client actions or payroll-related claims; (v) failure to manage growth of our operations and the effectiveness of our sales and marketing efforts; (vi) changes in the competitive environment in the PEO industry, including the entrance of new competitors and our ability to renew or replace client companies; (vii) our liability for worksite employee payroll, payroll taxes and benefits costs; (viii) our liability for disclosure of sensitive or private information; (ix) our ability to integrate or realize expected returns on our acquisitions; (x) failure of our information technology systems; and (xi) an adverse final judgment or settlement of claims against Insperity. These factors are discussed in further detail in Insperity’s filings with the U.S. Securities and Exchange Commission. Any of these factors, or a combination of such factors, could materially affect the results of our operations and whether forward-looking statements we make ultimately prove to be accurate.

Non-bonus payroll cost represents payroll cost excluding the impact of bonus payrolls paid to the company’s worksite employees. Bonus payroll cost varies from period to period, but has no direct impact to the company’s ultimate workers’ compensation costs under the current program. As a result, Insperity management refers to non-bonus payroll cost in analyzing, reporting and forecasting the company’s workers’ compensation costs.

EBITDA represents net income computed in accordance with generally accepted accounting principles (“GAAP”), plus interest expense, income tax expense, depreciation and amortization expense. Insperity management believes EBITDA and adjusted EBITDA are often useful measures of the company’s operating performance, as they allow for additional analysis of the company’s operating results separate from the impact of taxes and capital and financing transactions on earnings.

Adjusted net income and adjusted diluted net income per share of common stock represent net income and diluted net income per share computed in accordance with GAAP, excluding the impact of: i) a $3.3 million impairment charge associated with the Expense Management reporting unit in 2013; ii) a $2.0 million tax credit relating to tax years 2009 - 2012 and recorded in 2013; iii) a $2.7 million impairment charge related to The Receivables Exchange in 2013; and iv) a $4.2 million impairment charge associated with the Performance Management reporting unit in 2012. Under the two-class earnings per share method, the undistributed losses resulting from dividends exceeding net income in 2012 are not allocated to participating securities. Insperity management believes adjusted net income is a useful measure of the company’s operating performance in this period, as it allows for additional analysis of the company’s operating results separate from the impact of these items.

Non-bonus payroll, EBITDA, adjusted EBITDA, adjusted net income and adjusted diluted net income per share of common stock are not financial measures prepared in accordance with GAAP and may be different from similar measures used by other companies. Non-bonus payroll, EBITDA, adjusted EBITDA, adjusted net income and adjusted diluted net income per share of common stock should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. Insperity includes non-bonus payroll, EBITDA, adjusted EBITDA, adjusted net income and adjusted diluted net income per share of common stock in this press release because the company believes they are useful to investors in allowing for greater transparency related to the costs incurred under the company’s workers’ compensation program and the company’s operating performance during the periods presented. Investors are encouraged to review the reconciliation of the non-GAAP financial measures used in this press release to their most directly comparable GAAP financial measures as provided in the tables above.
