Barrett Business Services (BB1) Q3 2026 Earnings Report

The call was broadly positive, supported by revenue and gross billings growth, strong controllable customer additions, benefits momentum, asset-light market expansion, pricing execution, cost discipline, and substantial capital returns. However, existing-client workforce reductions, weaker staffing demand, regional softness, lower favorable workers' compensation adjustments, reduced worksite employee guidance, and lower earnings per share were notable challenges.

For the full year, BBSI continues to expect gross billings growth to increase between 3% and 4%, now expects average WSE growth of 1%-2% compared to its prior range of 2%-3% due to continued softness in client hiring, and continues to expect gross margin as a percentage of gross billings to be between 2.7% and 2.75%, with results now expected to be toward the lower end of the range; it also continues to expect its effective annual tax rate, normalized for the one-time charge in Q1, to be between 26% and 27%, while full year SG&A growth is expected to be lower than both gross billings growth and the prior year SG&A growth rate. Higher pricing and higher current-year workers’ compensation costs are expected to produce a full-year margin rate in line with prior years, and the company expects the trend of decreasing favorable prior-year liability and premium adjustments to continue.
