NORTHBROOK, IL, October 25, 2023 - IDEX Corporation (NYSE: IEX) today announced its financial results for the three month period ended September 30, 2023.
“IDEX delivered strong profitability and achieved record free cash flow in the third quarter,” said Eric D. Ashleman, IDEX Corporation Chief Executive Officer and President. “Our teams continue to execute for customers and shareholders in a dynamic environment of transition and recalibration.”
“We believe the divergent rates of destocking in our end markets have largely run their course, returning us to more typical backlog and lead time levels. Our focus is to leverage our 8020 philosophy and disproportionately allocate resources to those application niches with the highest potential.”
“We remain dedicated to our long-term focus as we continue to aggressively deploy capital to support organic growth and M&A. Our balance sheet has ample capacity to deliver on our goals, and our funnel of potential acquisitions remains strong and of high quality.”
2023 Outlook
Full year 2023 organic sales are projected to decline 1% to 2% over the prior year, with GAAP diluted EPS of $7.91 - $7.96 (adjusted diluted EPS of $8.13 - $8.18).
Fourth quarter 2023 organic sales are projected to decline 8% to 9% over the prior year period, with GAAP diluted EPS of $1.50 - $1.55 (adjusted diluted EPS of $1.74 - $1.79).

Orders
Third quarter 2023 orders of $712.3 million reflected a 9% decrease compared with the prior year period (-11% organic, -2% impact from the exit of a COVID-19 testing application in 2022 that did not reoccur in 2023, +3% acquisitions/divestitures and +1% foreign currency translation).
Net Sales
Third quarter 2023 net sales of $793.4 million reflected a 4% decrease compared with the prior year period (-6% organic, -2% impact from the exit of a COVID-19 testing application in 2022 that did not reoccur in 2023, +3% acquisitions/divestitures and +1% foreign currency translation).
Gross Margin
Third quarter 2023 gross margin of 44.1% decreased 220 basis points compared with the prior year period primarily due to the acceleration of previously deferred revenue related to the exit of a COVID-19 testing application in 2022 that did not reoccur in 2023, lower volume leverage, unfavorable mix, higher employee-related costs and the dilutive impact of acquisitions, partially offset by strong operational productivity and price/cost. Adjusted gross margin, which excludes the acceleration of previously deferred revenue and fair value inventory step-up charges, decreased 90 basis points compared with the prior year period.
Net Income and Diluted Earnings per Share Attributable to IDEX and Net Income Margin
Third quarter 2023 net income attributable to IDEX increased $30.4 million to $209.1 million, which resulted in diluted EPS attributable to IDEX of $2.75 per share, an increase of $0.39 per share, or 17%, from the prior year period. Third quarter 2023 net income margin of 26.3% increased 460 basis points compared with the prior year period. These increases were primarily driven by the gain on the sale of Micropump, Inc. ("Micropump") in 2023 as compared with the gain on the sale of Knight LLC and its related affiliates ("Knight") in 2022 as well as a lower effective tax rate of 20.2% compared to the third quarter 2022 effective tax rate of 21.8%. The decrease in the effective tax rate was driven by both the finalization of research expenditure capitalization treatment that served to increase tax benefits on foreign

source income and a tax election related to the acquisition of Muon B.V. and its subsidiaries (“Muon Group”) that reduced our minimum tax on foreign earnings. These favorable rate items were partially offset by tax recorded on the gain from the Micropump divestiture. These increases were partially offset by the lower operational results discussed above as well as higher amortization on new acquisitions and higher interest expense.
Adjusted EBITDA Margin and Adjusted Diluted EPS Attributable to IDEX
Third quarter 2023 Adjusted EBITDA margin of 28.4% decreased 30 basis points compared with the prior year period driven by lower volume leverage, unfavorable mix and the dilutive impact of acquisitions, partially offset by strong price/cost and operational productivity. Adjusted diluted EPS attributable to IDEX was $2.12 per share, a decrease of $0.02 per share, or 1%, from the prior year period reflecting the operating results previously discussed. Adjusted diluted EPS attributable to IDEX reflects the 11 cent impact of a lower effective tax rate.
Cash Flow
Third quarter 2023 cash from operations of $226.6 million was up 14% primarily due to lower working capital driven by inventory reductions in 2023 as compared to 2022. Third quarter 2023 free cash flow was $206.5 million, up 14% compared with the prior year period and constituted 129% 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 a business, 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 a business, 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 flows from operating activities less capital expenditures.
