QuoteFactors That Auger WellInsperity, being an integrated human resources and business solutions provider, offers a comprehensive suite of HR services solutions through professional employer organization (“PEO”) services known as Workforce Optimization and Workforce Synchronization solutions. With the help of these solutions, the company serves small- and medium-sized businesses in selected markets throughout the United States. Apart from PEO services, Insperity is also focusing on its Workforce Administration solution that provides human capital management and payroll services solution. Additional offerings of the company include time and attendance, organizational planning, recruiting services, employment screening, performance management, retirement services, as well as insurance services.Insperity looks strong on the back of a growing PEO industry which is currently being driven by the growth of small- and medium-sized businesses, increased need of providing employee benefits, increased costs related to workers’ compensation insurance coverage, workplace safety programs, employee-related complaints and litigation, and others.Insperity exited the March quarter with cash and equivalents of $575 million, which is above the total debt of $369 million. This indicates that the company has sufficient cash to meet its debt obligations. Moreover, Insperity does not have any current debt. Its total-debt-to-total-capital ratio was 0.83 at the end of first-quarter 2021, lower than the previous quarter’s 0.89. Lower debt-to-capitalization ratio indicates that the proportion of debt to finance the company’s assets is declining and so is the risk of insolvency.Expense Woes StayInsperity is seeing an increase in expenses as it continues to invest in growth, technology, and product and service offerings. In first-quarter 2021, operating expenses increased 12.6% year over year to $167.62 million. During 2020, adjusted operating expenses of $612.2 million increased 12.1% year over year. The same rose 10.7% year over year in 2019 and 12% in 2018.
