BBSI Reports Strong First Quarter 2023 Financial Results

- Q1 2023 Net Income of $0.8 Million, or $0.12 per Diluted Share -

VANCOUVER, Washington, May 3, 2023 – Barrett Business Services, Inc. (“BBSI” or the “Company”) (NASDAQ: BBSI), a leading provider of business management solutions, reported financial results for the first quarter ended March 31, 2023.

First Quarter 2023 Financial Summary vs. Year-Ago Quarter

“Through our combination of pricing discipline and leverage, we achieved record first quarter earnings,” said BBSI President and CEO, Gary Kramer. “We continue to see strong controllable growth from the addition of net new clients, and we’re off to a successful start in our new benefits offering. Client hiring was slower in the quarter than the prior year, but our results are in line with our expectations, and we remain optimistic about our strengthening value proposition for our clients.”

First Quarter 2023 Financial Results

Revenues in the first quarter of 2023 increased 3% to $254.7 million compared to $246.4 million in the first quarter of 2022.

Total gross billings in the first quarter of 2023 increased 5% to $1.79 billion compared to $1.71 billion in the same year-ago quarter (see “Key Performance Metrics” below). The increase was driven by WSEs from net client additions and net client hiring, as well as from higher average billings per WSE.

Workers’ compensation expense as a percent of gross billings was 2.9% in the first quarter of 2023 and benefited from a favorable adjustment of prior accident year liability of $1.1 million. This compares to 2.8% in the first quarter of 2022, which included a favorable adjustment of prior accident year liability of $2.9 million.

Net income for the first quarter of 2023 was $0.8 million, or $0.12 per diluted share, compared to $0.3 million, or $0.04 per diluted share, in the year-ago quarter. The increase is primarily attributable to growth in revenue.

Liquidity

As of March 31, 2023, unrestricted cash and investments were $132.7 million compared to $159.7 million at the end of 2022. BBSI was debt free at quarter end.

Key Performance Metrics

We report PEO revenues net of direct payroll costs because we are not the primary obligor for wage payments to our clients’ employees. However, management believes that gross billings and wages are useful in understanding the volume of our business activity and serve as an important performance metric in managing our operations, including the preparation of internal operating forecasts and establishing executive compensation performance goals. We therefore present for purposes of analysis gross billings and wage information for the three months ended March 31, 2023 and 2022.

In monitoring and evaluating the performance of our operations, management also reviews the following ratios, which represent selected amounts as a percentage of gross billings. Management believes these ratios are useful in understanding the efficiency and profitability of our service offerings.

We refer to employees of our PEO clients as WSEs. Management reviews average and ending WSE growth to monitor and evaluate the performance of our operations. Average WSEs are calculated by dividing the number of unique individuals paid in each month by the number of months in the period. Ending WSEs represents the number of unique individuals paid in the last month of the period.
