"We capped off a record year with strong fourth quarter results, driven by consistent execution against our priorities,” said Rob Bodor, President and Chief Executive Officer. “For the full year, we generated revenue above $500 million for the first time in our 25-year history, while delivering improved earnings, robust cash flow, and substantial capital returned to shareholders. We are encouraged by our strong finish to 2023, and we believe we have the right strategy and priorities in place to continue our momentum throughout 2024. We remain focused on driving positive global impact, maintaining our industry-leading financial model, and increasing value for our shareholders." Dan Schumacher, Chief Financial Officer, commented, "Along with record revenue in 2023, we significantly improved profitability in both the digital factory and the digital network.

We generated an industry-leading $73 million in cash from operations, and we paid 97% of our free cash flows to shareholders through share repurchases."

The Company will continue to provide financial guidance on a quarterly basis due to the quick-turn nature of the business and continued uncertainty in global manufacturing.

For the first quarter of 2024, the Company expects to generate revenue between $120 million and $128 million. This guidance reflects a softer start to 2024, due to December 2023 and early January 2024 order levels being lower than historical periods. However, recent performance has been more in line with historical trends, and our guidance assumes that will continue through the end of March.

The Company expects first quarter 2024 diluted net income per share between $0.09 and $0.17, and non-GAAP diluted net income per share between $0.26 and $0.34. See "Non-GAAP Financial Measures" below.
