Insperity will be hosting a conference call today at 10:00 a.m. ET to discuss these results and our updated 2022 outlook, and has posted an accompanying presentation to its investor website at http://ir.insperity.com.

Third Quarter Results

For the third quarter of 2022, reported net income and diluted earnings per share (“EPS”) were $37.7 million and $0.98, respectively. Adjusted EPS increased 38.2% over the third quarter of 2021 to $1.23. Adjusted EBITDA increased 32.7% to $79.8 million.

The average number of worksite employees (“WSEEs”) paid per month increased 17.8% over Q3 2021 to 303,347 WSEEs. WSEEs paid from new client sales improved over Q3 2021 and client retention remained strong, averaging 99% per month for the quarter. The net gain in our client base continued, although at expected lower levels than Q3 2021, a period when many clients were rehiring employees as the pandemic conditions improved. Revenues in Q3 2022 increased 19.0% to $1.4 billion on the 17.8% increase in paid WSEEs. Revenue per WSEE was up 1.0% as overall pricing was managed to targeted levels given the current inflationary environment, partially offset by a client and worksite employee mix change.

“We are pleased to report continuing strong growth and profitability this quarter and year to date driven by a combination of strong demand for our services and excellent execution by our Insperity employees,” said Paul J. Sarvadi, Insperity chief executive officer and chairman. “We have successfully launched our fall selling and retention campaign, and are focused on finishing an excellent first year of our five year plan and achieving a strong start to 2023.”

Gross profit increased 23.2% over Q3 2021 to $244.6 million on the 17.8% increase in paid WSEEs and a 4.7% increase in gross profit per WSEE per month. Benefits costs were better than expected, driven by lower utilization, including COVID related costs. Gross profit contribution from our workers’ compensation program improved over Q3 2021, further driving the increase in gross profit per WSEE per month.

Operating expenses increased 20.8% over Q3 2021 on the 23.2% increase in gross profit. Operating spend included continued investment in our service personnel given our high growth and a focus on hiring and retention in the current tight labor market. Other Q3 2022 personnel costs included a higher incentive compensation accrual tied to our outperformance. Travel and event costs also increased over Q3 2021, which was more restrictive under the pandemic conditions.

Year-to-Date Results

Revenues for the first nine months of 2022 increased 20.8% to $4.4 billion on an 18.9% increase in paid WSEEs and a 1.7% increase in revenue per WSEE. Gross profit for the first nine months of 2022 increased 18.6% to $770.2 million. Operating expenses increased 16.3% to $570.8 million compared to the 2021 period.

For the nine months ended September 30, 2022, reported net income and diluted EPS were $141.2 million and $3.66, respectively. Adjusted EPS increased 21.0% compared to the first nine months of 2021 to $4.38. Adjusted EBITDA increased 21.8% compared to the first nine months of 2021 to $273.4 million.

Net income per WSEE per month increased 3.8% to $54 in the 2022 period from $52 in the 2021 period. Adjusted EBITDA per WSEE per month was $104 in the 2022 period compared to $102 in the 2021 period.

Gross profit and earnings comparisons are impacted by the non-recurrence of $16.8 million in federal payroll tax refunds received in 2021 related to prior years.

Cash outlays in the first nine months of 2022 included the repurchase of approximately 679,000 shares of stock at a cost of $63.4 million, dividends totaling $56.9 million and capital expenditures of $16.4 million. Adjusted cash totaled $239 million at September 30, 2022 and $280 million is available under our recently expanded $650 million credit facility.

“In spite of the lingering pandemic conditions and the recent economic uncertainty, we have been able to achieve over a 20% increase in Adjusted EBITDA and Adjusted EPS over the first three quarters of this year,” said Douglas S. Sharp, Insperity executive vice president of finance, chief financial officer and treasurer. “While some uncertainty surrounding these factors continues to exist, we remain focused on taking advantage of the ongoing market opportunity and executing our long-term plan as we head into 2023.”

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.
EBITDA	Represents net income computed in accordance with GAAP, plus: •  interest expense, •  income tax expense, •  depreciation and amortization expense, and •  amortization of SaaS implementation costs.
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.
