Consolidated revenues for the fourth quarter were $1.1 billion, down 6.6 percent over the fourth quarter of 2022. From an industry perspective, the Company operates in six broad industry verticals. Commercial Segment revenues (69.7 percent of total revenues), were down 12.2 percent year-over-year and are categorized into five verticals: (i) Financial Services, (ii) Consumer and Industrial, (iii) Technology, Media and Telecom ("TMT"), (iv) Healthcare, and (v) Business and Government Services. Consumer and Industrial and Healthcare verticals saw mid-single-digit revenue declines year-over-year and the remaining three verticals saw double-digit declines year-over-year. Federal Government Segment revenues (30.3 percent of total revenues), the sixth industry vertical, were up 9.2 percent year-over-year.

Total IT consulting services revenues were $594.0 million (55.3 percent of total revenues), up 5.6 percent year-over-year. Federal Government Segment revenues, which are all consulting revenues, were $325.5 million, up 9.2 percent year-over-year as stated above, and Commercial Segment consulting revenues were $268.5 million, up 1.7 percent year-over-year. The growth in IT consulting services revenues was offset by a 18.4 percent year-over-year decline in assignment revenues, which totaled $480.1 million (44.7 percent of total revenues), reflecting continued softness in the more cyclical portions of the Commercial Segment business.

Gross margin for the fourth quarter of 2023 was 28.4 percent, down 120 basis points from the fourth quarter of 2022. The compression mainly related to business mix: (i) within the Commercial Segment, a lower mix of certain high-margin assignment revenues, namely, creative digital marketing and permanent placement revenues, which was partially offset by a higher mix of high-margin IT consulting revenues with a year-over-year expansion in margin and (ii) a higher mix of revenues from the Federal Government Segment, which have a lower gross margin than commercial revenues.

Selling, general and administrative (“SG&A”) expenses were $203.6 million (19.0 percent of revenues), compared with $229.9 million (20.0 percent of revenues) from the fourth quarter of 2022. This improvement was primarily due to lower incentive compensation expense. SG&A expenses included $1.6 million in acquisition, integration and strategic planning expenses, which were not included in the Company's previously-announced guidance estimates.

Net income was $50.3 million ($1.06 per diluted share), compared with $55.6 million ($1.10 per diluted share) from the fourth quarter of 2022.

Adjusted EBITDA (a non-GAAP measure) was $121.0 million, or 11.3 percent of revenues ("Adjusted EBITDA margin", a non-GAAP measure), compared with $131.9 million or 11.5 percent of revenues in the fourth quarter of 2022.

Capital Resources and Capital Allocation

At December 31, 2023, the Company had:

•Cash and cash equivalents of $175.9 million

•Full availability under its $500.0 million Senior Secured Revolving Credit Facility (due 2028)

•Senior Secured Debt of $498.8 million (term loan B facility due 2030)

•Senior unsecured notes totaling $550.0 million at 4.625 percent (due 2028)

In the fourth quarter of 2023 the Company repurchased 872,952 shares of its common stock for $75.4 million at an average price of $86.37 per share. Approximately $273.7 million remained available at quarter end for repurchases under the Company's stock repurchase plan.

First Quarter 2024 Financial Estimates

The Company's financial estimates for the first quarter of 2024, which are set forth below, are based on current operating trends and assume no significant deterioration in the markets ASGN serves. These estimates do not include any acquisition, integration or strategic planning expenses. Reconciliations of estimated net income to the estimated non-GAAP financial measures are included in the tables that accompany this release.


(In millions, except per share data)	Low			High
Revenues	$	1,032.0		$	1,052.0
SG&A expenses(1)	205.1			208.4
Amortization of intangible assets	15.1			15.1

Net income	37.7			41.3


Diluted earnings per share	$	0.80		$	0.87


Gross margin	28.0		%	28.3		%
Effective tax rate(2)	28.0		%	28.0		%

Non-GAAP Financial Measures:
Adjusted EBITDA	$	104.5		$	109.5
Adjusted Net Income(3)	$	52.2		$	55.8
Adjusted Net Income per diluted share(3)	$	1.10		$	1.18
Adjusted EBITDA Margin	10.1		%	10.4		%

___________

(1) Includes non-cash expenses totaling $20.0 million, comprised of: (i) $11.9 million of stock-based compensation, (ii) $7.0 million of depreciation and (iii) $1.1 million of amortization related to capitalized cloud-based application implementation costs.

(2) Estimated effective tax rate before any excess tax benefits related to stock-based compensation.

(3) Does not include the “Cash Tax Savings on Indefinite-lived Intangible Assets.” These savings total $8.5 million each quarter, or $0.18 per diluted share, and represent the benefit of the tax deduction that ASGN receives from the amortization of goodwill and trademarks.

The financial estimates above are based on an estimate of “Billable Days”, which are Business Days (calendar days for the period less weekends and holidays) adjusted for other factors, such as the day of the week a holiday occurs, additional time taken off around holidays, year-end client furloughs and inclement weather. There are 62.75 Billable Days in the first quarter of 2024, which is 0.25 days fewer than the year ago period and 2.75 days more than Q4 2023. The above estimates also include the effects of the payroll tax reset, which occurs at the beginning of each year. These annual resets cause, among other things, lower gross and Adjusted EBITDA margins in the first quarter of the year.

Non-GAAP Financial Measures

Statements in this release and the accompanying financial information include non-GAAP financial measures that are provided as additional information to enhance the overall understanding of the Company's current financial performance and not as an alternative to the consolidated interim financial statements presented in accordance with accounting principles generally accepted in the United States ("GAAP"). Management uses these non-GAAP measures (EBITDA, Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income, Adjusted Net Income per diluted share, Free Cash Flow and Revenues on a same Billable Days basis) to evaluate the Company's financial performance. These terms might not be calculated in the same manner as, and thus might not be comparable to, similarly titled measures reported by other companies. The financial information tables that accompany this press release include reconciliations of net income to non-GAAP financial measures.

EBITDA, Adjusted EBITDA and Adjusted EBITDA margin provide a measure of the Company's operating results in a manner that is focused on the performance of the Company's core business on an ongoing basis, by removing the effects of non-operating and certain non-cash expenses. These non-operating and non-cash items are specifically identified in the reconciliations of GAAP measures to Non-GAAP measures that accompany this release.

Adjusted Net Income provides a method for assessing the Company's operating results in a manner that is focused on the performance of the Company's core business on an ongoing basis by removing the effects of non-operating and certain non-cash expenses, adjusted for some of the cash flows associated with amortization of intangible assets to more fully present the performance of the Company's acquisitions. The calculation of Adjusted Net Income is presented in the reconciliations of GAAP measures to Non-GAAP measures that accompany this release.

Free Cash Flow provides useful information to investors about the amount of cash generated by the business that can be used for strategic opportunities and is computed as presented in the tables that accompany this release.
