Amortization of intangibles and acquisition and divestiture-related costs are excluded from non-GAAP measures as the timing and magnitude of business combination transactions are not predictable, can vary significantly from period to period and the purchase price allocated to amortizable intangible assets and the related amortization period are unique to each acquisition. Amortization of intangible assets will recur in future periods until such intangible assets have been fully amortized. While intangible assets contribute to the company’s revenue generation, the amortization of intangible assets does not directly relate to the sale of the company’s products or services. Additionally, intangible assets amortization expense typically fluctuates based on the size and timing of the company’s acquisition activity. Accordingly, the company believes excluding the amortization of intangible assets enhances the company’s and investors’ ability to compare the company’s past financial performance with its current performance and to analyze underlying business performance and trends. Although stock-based compensation is a key incentive offered to certain of our employees, the expense is non-cash in nature, and we continue to evaluate our business performance excluding stock-based compensation; therefore, it is excluded from non-GAAP measures. Stock-based compensation expenses will recur in future periods. Charges related to restructuring and cost optimization plans, impairment charges, including goodwill, divestiture gains or losses, and the costs, including legal fees, related to significant or unusual litigation matters are excluded from non-GAAP measures as the frequency and magnitude of these activities may vary widely from period to period. Additionally, impairment charges, including goodwill, are non-cash. Furthermore, the company believes the costs, including legal fees, related to significant or unusual litigation matters are not indicative of our core business’ operations. Finally, 3D Systems excludes contingent consideration recorded as compensation expense related to the 2021 Volumetric acquisition from non-GAAP measures as management evaluates financial performance excluding this expense, which is viewed by management as similar to acquisition consideration.
The matters discussed above are tax effected, as applicable, in calculating non-GAAP diluted income (loss) per share.
Adjusted EBITDA, defined as net income, plus income tax (provision) benefit, interest and other income (expense), net, stock-based compensation expense, amortization of intangible assets, depreciation expense, and other non-GAAP adjustments, all as described above, is used by management to evaluate performance and helps measure financial performance period-over-period.
A reconciliation of GAAP to non-GAAP measures is provided in the accompanying schedules.
3D Systems does not provide forward-looking guidance for certain measures on a GAAP basis. The company is unable to provide a quantitative reconciliation of forward-looking non-GAAP gross profit margin, Adjusted EBITDA, and non-GAAP operating expense to the most directly comparable forward-looking GAAP measures without unreasonable effort because certain items, including litigation costs, acquisition expenses, stock-based compensation expense, intangible assets amortization expense, restructuring expenses, and goodwill impairment charges are difficult to predict and estimate. These items are inherently uncertain and depend on various factors, many of which are beyond the company’s control, and as such, any associated estimate and its impact on GAAP performance could vary materially.
