Insperity Announces Third Quarter Results

HOUSTON – Nov. 2, 2020 – Insperity, Inc. (NYSE: NSP), a leading provider of human resources and business performance solutions for America’s best businesses, today reported results for the third quarter ended Sep. 30, 2020:

•Q3 net income and diluted EPS of $20 million and $0.51, respectively

•Q3 adjusted EPS up 21% to $0.91

•Q3 adjusted EBITDA up 13% to $58 million

•YTD net income and diluted EPS of $134 million and $3.43, respectively

•YTD adjusted EBITDA and adjusted EPS up 20% and 16% to $251 million and $4.15, respectively

•Share repurchase authorization expanded by one million shares

Third Quarter Results

For the third quarter of 2020, reported net income and diluted earnings per share (“EPS”) were $20 million and $0.51, respectively. Adjusted EPS increased 21% over the 2019 period to $0.91. Adjusted EBITDA increased 13% to $57.6 million. The difference between GAAP EPS and Adjusted EPS was primarily caused by performance driven stock-based compensation.

“These excellent results reflect outperformance in worksite employee growth and pricing relative to our expectations in the midst of an uncertain business environment. These developments, together with favorable results in our direct cost programs, more than offset the impact of layoffs within our client base brought about by the pandemic,” said Paul J. Sarvadi, Insperity chief executive officer and chairman. “We expect the strength of our business model, the dedication of our staff, and the resiliency of our client base to be important factors as we look ahead with confidence into 2021.”

The average number of worksite employees (“WSEEs”) paid per month in Q3 2020 increased 1.7% sequentially over the Q2 period to 231,750 WSEEs, which was above the high end of our expected range. A continued improvement over the course of the pandemic from the low point experienced in May 2020 was driven by (1) WSEEs hired or returning to work outpacing layoffs, (2) client retention for both Q2 and Q3 remaining at our historical level of 99% and (3) the addition of WSEEs from solid new client sales throughout the pandemic.

“We are pleased with our recent sequential growth and expect paid worksite employees to return to near pre-pandemic levels by the end of the year,” said Douglas S. Sharp, Insperity senior vice president of finance, chief financial officer and treasurer. “Additionally, strong execution in pricing, effective management of our direct cost programs and operating expenses, and the dynamics of the pandemic on our business has driven our recent substantial outperformance.”

Average pricing increased 4.4% over the 2019 period, which more than offset the 3.8% year-over-year decline in average paid WSEEs driven by the pandemic. However, total revenues decreased 3% from Q3 2019 to $1.0 billion, due to the FICA deferral program instituted as part of the CARES Act.

Gross profit increased by 8% over Q3 2019 to $185.0 million. This greater than expected increase resulted from the higher than anticipated paid WSEEs and pricing, combined with significant favorable results in benefits and workers’ compensation costs. Lower than expected benefit costs were primarily associated with favorable claims development from less healthcare utilization. Lower workers’ compensation costs were primarily attributable to the effective management of claims incurred in periods prior to the pandemic.

Operating expenses increased 15% over Q3 2019 and included a 10% increase in the number of trained Business Performance Advisors. In spite of an increased workload from the pandemic, we have held other corporate headcount flat and achieved cost savings in other areas, including travel, training and other general and administrative costs. An increase in stock-based compensation was driven by our recent outperformance in the level

of paid WSEEs and earnings. Operating expenses, excluding stock-based compensation and depreciation and amortization, increased by 5% over Q3 2019.

Year-to-Date Results

For the nine months ended September 30, 2020, reported net income and diluted EPS were $134.0 million and $3.43, respectively. Adjusted EPS increased 16% over the first nine months of 2019 to $4.15. Adjusted EBITDA increased 20% over the first nine months of 2019 to $250.8 million.

Revenues for the first nine months of 2020 were flat at $3.2 billion, as the improvement in the average number of paid WSEEs from the low point in May 2020 has resulted in the year-to-date average paid WSEEs per month being essentially unchanged compared to the 2019 period. Gross profit for the first nine months of 2020 increased 12% to $639.3 million. Operating expenses increased 10% to $452.3 million over the 2019 period.

Net income per WSEE per month increased 3% from $62 in the 2019 period to $64 in the 2020 period. Adjusted EBITDA per WSEE per month increased 20% from $100 in the 2019 period to $120 in the 2020 period.

Cash outlays in the first nine months of 2020 included the repurchase of approximately 1,337,000 shares of stock at a cost of $91.2 million, dividends totaling $46.5 million and capital expenditures of $68.8 million. Adjusted cash totaled $213 million at September 30, 2020 and $130 million remains available under our $500 million credit facility.

Share Repurchase Expansion

Insperity’s board of directors has authorized an expansion of its stock repurchase program by an additional one-million shares, and as a result will have approximately 1.2 million shares available for repurchase. Purchases may be made from time to time in the open market or in privately negotiated transactions. The company may also adopt Rule 10b5-1 prearranged stock trading plans designed to facilitate Insperity’s repurchase of its common stock during times it would not otherwise be in the open market due to self-imposed trading blackout periods or possible possession of material nonpublic information.

2020 Guidance

The company also announced its updated guidance for 2020, including the fourth quarter of 2020. Please refer to the accompanying financial tables at the end of this press release for the reconciliation of non-GAAP financial measures to the comparable GAAP financial measures.

	Q4 2020			Full Year 2020
Average WSEEs paid (a)	236,500	—	238,500	233,500	—	234,000
Year-over-year decrease	(3.0)%	—	(2.1)%	(0.9)%	—	(0.7)%
Adjusted EPS (b)	$0.20	—	$0.38	$4.35	—	$4.53
Year-over-year increase (decrease)	(65)%	—	(33)%	5%	—	9%
Adjusted EBITDA (in millions) (b)	$20.5	—	$30.0	$271	—	$281
Year-over-year increase (decrease)	(50)%	—	(26)%	8%	—	12%

____________________________________

(a)Q4 2020 guidance for average WSEEs paid represents 2% to 3% sequential growth compared to Q3 2020.

(b)Q4 2020 guidance for Adjusted EPS and Adjusted EBITDA reflects an expected shift in the timing of health care utilization during the pandemic into Q4 2020. This shift is primarily the result of the deferral of non-essential procedures, including costs associated with participants with chronic conditions that missed treatments. As a result, the 2020 quarterly earnings pattern varies significantly from 2019.

Definition of Key Metrics

Average WSEEs paid - Determined by calculating the company’s cumulative worksite employees paid during the period divided by the number of months in the period.

Adjusted EPS - Represents diluted net income per share computed in accordance with GAAP, excluding the impact of non-cash stock-based compensation.

Adjusted EBITDA - Represents net income computed in accordance with GAAP, plus interest expense, income taxes, depreciation and amortization expense and non-cash stock-based compensation.

NON-GAAP FINANCIAL MEASURES

Insperity, Inc.

Non-GAAP Financial Measures

(Unaudited)

Non-GAAP financial measures are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of the non-GAAP financial measures used to their most directly comparable GAAP financial measures as provided in the tables below.

Non-GAAP Measure	Definition	Benefit of Non-GAAP Measure
Non-bonus payroll cost	Non-bonus payroll cost is a non-GAAP financial measure that excludes the impact of bonus payrolls paid to our WSEEs. Bonus payroll cost varies from period to period, but has no direct impact to our ultimate workers’ compensation costs under the current program.	Our management refers to non-bonus payroll cost in analyzing, reporting and forecasting our workers’ compensation costs. We include these non-GAAP financial measures because we believe they are useful to investors in allowing for greater transparency related to the costs incurred under our current workers’ compensation program.
Adjusted cash, cash equivalents and marketable securities	Excludes funds associated with: •  federal and state income tax withholdings, •  employment taxes, •  other payroll deductions, and •  client prepayments.	We believe that the exclusion of the identified items helps us reflect the fundamentals of our underlying business model and analyze results against our expectations, against prior periods, and to plan for future periods by focusing on our underlying operations. We believe that the adjusted results provide relevant and useful information for investors because they allow investors to view performance in a manner similar to the method used by management and improves their ability to understand and assess our operating performance. Adjusted EBITDA is used by our lenders to assess our leverage and ability to make interest payments.
Adjusted operating expenses	Represents operating expenses excluding the impact of the following: •  non-cash stock-based compensation, and •  depreciation and amortization expense.
EBITDA	Represents net income computed in accordance with GAAP, plus: •  interest expense, •  income tax expense, and •  depreciation and amortization expense.
Adjusted EBITDA	Represents EBITDA plus: •  non-cash stock-based compensation.
Adjusted net income	Represents net income computed in accordance with GAAP, excluding: •  non-cash stock-based compensation.
Adjusted EPS	Represents diluted net income per share computed in accordance with GAAP, excluding: •  non-cash stock-based compensation.
