NORTHBROOK, IL, FEBRUARY 6, 2024 - IDEX Corporation (NYSE: IEX) today announced its financial results for the quarter and year ended December 31, 2023.
“IDEX businesses weathered an unprecedented year of global recalibration, which played out differently across our segments. Our team’s agility and core execution capabilities, combined with the quality of our underlying assets, enabled us to deliver strong results in a challenging environment,” said Eric D. Ashleman, IDEX Corporation Chief Executive Officer and President.
“Now, the majority of our end markets are stable, supporting the early stages of focused organic growth to drive our next chapter of outperformance. However, the timing of market recovery within our Life Sciences and Analytical Instrumentation businesses remains uncertain, moderating our overall full year growth outlook.”
“We continue to aggressively pursue inorganic opportunities within advantaged, fast-growing markets, as demonstrated by our purchase of STC Material Solutions in December. Our funnel of potential acquisitions is strong and our efforts are well supported by ample capacity on our balance sheet.”
2024 Outlook
Full year 2024 organic sales growth is projected to be 0% to 2% over the prior year, with GAAP diluted EPS of $7.15 to $7.45 (adjusted diluted EPS of $8.15 to $8.45).
First quarter 2024 organic sales are projected to decline 6% to 7% from the prior year period, with GAAP diluted EPS of $1.45 to $1.50 (adjusted diluted EPS of $1.70 to $1.75).

Orders
Fourth quarter 2023 orders of $753.9 million reflected a 6% decrease compared with the prior year period (-10% organic, +3% acquisitions/divestitures and +1% foreign currency translation).
Full year 2023 orders of $3,057.6 million reflected a 7% decrease compared with 2022 (-11% organic, -1% impact from the exit of a COVID-19 testing application in 2022 that did not reoccur in 2023 and +5% acquisitions/divestitures).
Net Sales
Fourth quarter 2023 sales of $788.9 million reflected a 3% decrease compared with the prior year period (-6% organic and +3% acquisitions/divestitures).
Full year 2023 sales of $3,273.9 million reflected a 3% increase compared with 2022 (+5% acquisitions/divestitures, -1% organic and -1% impact from the exit of a COVID-19 testing application).
Gross Margin
Fourth quarter 2023 gross margin of 42.7% increased 10 basis points compared with the prior year period primarily due to strong price/cost, lower fair value inventory step-up charges and favorable operational productivity, partially offset by lower volume leverage, higher employee-related costs partly mitigated by lower variable compensation, the dilutive impact of acquisitions and unfavorable mix. Adjusted gross margin, which excludes fair value inventory step-up charges, decreased 90 basis points compared with the prior year period.
Full year 2023 gross margin of 44.2% decreased 60 basis points compared with 2022 primarily due to lower volume leverage, the dilutive impact of acquisitions, higher employee-related costs partly mitigated by lower variable compensation, unfavorable mix and the acceleration of previously deferred revenue related to the exit of a COVID-19 testing application in 2022 that did not reoccur in 2023, partially offset

by strong operational productivity and price/cost as well as lower fair value inventory step-up charges. Adjusted gross margin, which excludes the acceleration of previously deferred revenue discussed above and fair value inventory step-up charges, decreased 60 basis points compared with 2022.
Net Income and Diluted Earnings per Share Attributable to IDEX and Net Income Margin
Fourth quarter 2023 net income attributable to IDEX decreased $21.4 million to $108.6 million, which resulted in diluted EPS attributable to IDEX of $1.43 per share, a decrease of $0.28 per share, or 16%, from the prior year period. Fourth quarter 2023 net income margin of 13.7% decreased 230 basis points compared with the prior year period. These decreases were primarily driven by lower operating results discussed above as well as a loss on the sale of Novotema, SpA ("Novotema") and amortization on new acquisitions, partially offset by higher fair value inventory step-up charges in the prior year period. The fourth quarter 2023 effective tax rate of 22.7% increased compared with the fourth quarter 2022 effective tax rate of 20.5% primarily due to the one-time foreign currency benefits realized in 2022 in connection with the funding of the acquisition of Muon B.V. and its subsidiaries ("Muon Group") as well as the impact of the loss recorded on the sale of Novotema during 2023, for which no related tax benefit was realized due to the type of consolidated group in which it participated.
Full year 2023 net income attributable to IDEX increased $9.2 million to $596.1 million, which resulted in diluted EPS attributable to IDEX of $7.85 per share, an increase of $0.14 per share, or 2%, compared with 2022. Full year 2023 net income margin of 18.2% decreased 20 basis points compared with 2022. The increase in net income attributable to IDEX was primarily driven by higher gains on the sale of businesses and lower fair value inventory step-up charges, partially offset by lower operating results discussed above, amortization on new acquisitions, higher interest expense and a reserve recorded on an investment with a collaborative partner. The full year 2023 GAAP effective tax rate of 21.7% was flat when compared with the full year 2022 GAAP effective tax rate. Both years included one-time benefits that lowered the effective tax rate.
Adjusted EBITDA Margin and Adjusted Diluted EPS Attributable to IDEX
Fourth quarter 2023 Adjusted EBITDA margin of 25.8% decreased 120 basis points compared with the prior year period driven by lower volume leverage, higher employee-related costs partly mitigated by lower variable compensation, unfavorable mix and the dilutive impact of acquisitions, partially offset by strong price/cost and operational productivity. Adjusted diluted EPS attributable to IDEX was $1.83 per share, a decrease of $0.18 per share, or 9%, from the prior year period reflecting the operating results previously discussed. Adjusted diluted EPS excludes the impacts of the sale of Novotema discussed above.
Full year 2023 Adjusted EBITDA margin of 27.5% decreased 40 basis points compared with 2022 driven by lower volume leverage, higher employee-related costs and unfavorable mix, partially offset by strong price/cost and operational productivity. Adjusted diluted EPS attributable to IDEX was $8.22 per share, an increase of $0.10 per share, or 1%, compared with 2022 reflecting higher operating results. Additionally, 2023 included higher interest expense, which was mostly offset by the 9 cent impact of a lower adjusted effective tax rate in 2023, which excludes the impacts of the sale of businesses.
Cash Flow
Fourth quarter and full year 2023 cash from operations of $201.0 million and $716.7 million, respectively, were up compared with the prior year period primarily due to lower working capital driven by inventory reductions in 2023 as compared to 2022. Fourth quarter 2023 free cash flow was $179.4 million, up 22% compared with the prior year period and constituted 129% of adjusted net income attributable to IDEX, while full year 2023 free cash flow of $626.8 million, up 28% compared with 2022, constituted 101% of adjusted net income attributable to IDEX.

Non-GAAP Measures of Financial Performance
The Company prepares its public financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP). The Company supplements certain GAAP financial performance metrics with non-GAAP financial performance metrics. Management believes these non-GAAP financial performance metrics provide investors with greater insight, transparency and a more comprehensive understanding of the financial information used by management in its financial and operational decision making because certain of these adjusted metrics exclude items not reflective of ongoing operations, as identified in the reconciliations below. Reconciliations of non-GAAP financial performance metrics to their most directly comparable GAAP financial performance metrics are defined and presented below and should not be considered a substitute for, nor superior to, the financial data prepared in accordance with GAAP. Due to rounding, numbers presented throughout this and other documents may not add up or recalculate precisely. There were no adjustments to GAAP financial performance metrics other than the items noted below.
•Organic orders and net sales are calculated excluding amounts from acquired or divested businesses during the first twelve months of ownership or prior to divestiture, the impact of foreign currency translation and the impact from the exit of a COVID-19 testing application.
•Adjusted net sales is calculated as net sales less the acceleration of previously deferred revenue related to the exit of a COVID-19 testing application.
•Adjusted gross profit is calculated as gross profit less the impact from the exit of a COVID-19 testing application plus fair value inventory step-up charges.
•Adjusted gross margin is calculated as adjusted gross profit divided by adjusted net sales.
•Adjusted net income attributable to IDEX is calculated as net income attributable to IDEX plus fair value inventory step-up charges, plus restructuring expenses and asset impairments, less the net impact from the exit of a COVID-19 testing application, less the gain on sale of businesses - net, less gains on sales of assets, plus the credit loss on a note receivable from a collaborative partner, plus acquisition-related intangible asset amortization, all net of the statutory tax expense or benefit.
•Adjusted diluted EPS attributable to IDEX is calculated as adjusted net income attributable to IDEX divided by the diluted weighted average shares outstanding.
•Consolidated Adjusted EBITDA is calculated as consolidated earnings before interest, taxes, depreciation and amortization, or consolidated EBITDA, plus fair value inventory step-up charges, plus restructuring expenses and asset impairments, less the net impact from the exit of a COVID-19 testing application, less the gain on sale of businesses - net, less gains on sales of assets plus the credit loss on a note receivable from a collaborative partner.
•Consolidated Adjusted EBITDA margin is calculated as Consolidated Adjusted EBITDA divided by adjusted net sales.
•Free cash flow is calculated as cash flow from operating activities less capital expenditures.
