________________________________________________________________________________

CORK, Ireland, February 1, 2023 -- Johnson Controls International plc (NYSE: JCI), a global leader for smart, healthy and sustainable buildings, today reported fiscal first quarter 2023 GAAP earnings per share (“EPS”) from continuing operations, including special items, of $0.17. Excluding special items, adjusted EPS from continuing operations was $0.67, up 24% versus the prior year period (see attached footnotes for non-GAAP reconciliation).

Sales in the quarter of $6.1 billion increased 4% compared to the prior year on an as reported basis and grew 9% organically. GAAP net income from continuing operations was $118 million. Adjusted net income from continuing operations of $463 million was up 22% versus the prior year. Earnings before interest and taxes (“EBIT”) was $237 million and EBIT margin was 3.9%. Adjusted EBIT was $646 million and adjusted EBIT margin was 10.6%, improving 140 basis points versus the prior year.

“Johnson Controls delivered solid first quarter results,” said George Oliver, Chairman and Chief Executive Officer. “Our momentum remains strong, and we are uniquely positioned to accelerate growth across our service-based businesses and expand our digital solutions through our innovative OpenBlue platform. Our unique offerings enable us to lead the future of smart, healthy and sustainable buildings.”

“Our earnings results came in at the high end of our guidance as we executed on our higher margin backlog, delivered on our productivity initiatives and improved our operational execution,” said Olivier Leonetti, Chief Financial Officer. “Our pipeline remains robust, and we are well positioned to capture tailwinds across our vectors of growth and deliver strong financial performance.”

Income and EPS amounts attributable to Johnson Controls ordinary shareholders

($ millions, except per-share amounts)

The financial highlights presented in the tables below are in accordance with GAAP, unless otherwise indicated. All comparisons are to the fiscal first quarter of 2022.

Organic sales growth, adjusted sales, organic segment EBITA growth, total segment EBITA, adjusted segment EBITA, adjusted corporate expense, EBIT, adjusted EBIT, adjusted net income from continuing operations, adjusted EPS from continuing operations, and free cash flow are non-GAAP financial measures. For a reconciliation of non-GAAP measures and detail of the special items, refer to the attached footnotes.

This press release includes forward-looking statements regarding organic revenue growth, adjusted segment EBITA margin improvement and adjusted EPS, which are non-GAAP financial measures. These non-GAAP financial measures are derived by excluding certain amounts from the corresponding financial measures determined in accordance with GAAP. The determination of the amounts excluded is a matter of management judgment and depends upon, among other factors, the nature of the underlying expense or income amounts recognized in a given period and the high variability of certain amounts, such as mark-to-market adjustments. Organic revenue growth excludes the effect of acquisitions, divestitures and foreign currency. We are unable to present a quantitative reconciliation of the aforementioned forward-looking non-GAAP financial measures to their most directly comparable forward-looking GAAP financial measures because such information is not available, and management cannot reliably predict the necessary components of such GAAP measures without unreasonable effort or expense. The unavailable information could have a significant impact on the Company’s fiscal 2023 second quarter and full year GAAP financial results.

A slide presentation to accompany the results can be found in the Investor Relations section of Johnson Controls’ website at http://investors.johnsoncontrols.com.

Non-GAAP Financial Information

This press release contains financial information regarding adjusted earnings per share, which is a non-GAAP performance measure. The adjusting items include restructuring and impairment costs, net mark-to-market adjustments, Silent-Aire other nonrecurring items, certain transaction/separation costs, and warehouse fire loss.

(1) The Company's press release contains financial information regarding total segment EBITA, adjusted segment EBITA and adjusted segment EBITA margins, which are non-GAAP performance measures. The Company's definition of adjusted segment EBITA excludes other non-recurring items (hereafter referred to as "special items") because these costs are not considered to be directly related to the underlying operating performance of its businesses. Management believes these non-GAAP measures are useful to investors in understanding the ongoing operations and business trends of the Company.

A reconciliation of total segment EBITA to net income is shown earlier within this footnote. The following is the three months ended December 31, 2022 and 2021 reconciliation of total segment EBITA and segment EBITA margin as reported to adjusted segment EBITA and adjusted segment EBITA margin (unaudited):

(2) Adjusted Corporate expenses for the three months ended December 31, 2022 excludes certain transaction/separation costs of $27 million.

(3) Adjusted amortization of intangible assets for the three months ended December 31, 2021 excludes $7 million of nonrecurring intangible asset amortization related to Silent-Aire purchase accounting.

(4) Adjusted results for the three months ended December 31, 2022 exclude net mark-to-market gains on restricted asbestos investments and pension and postretirements plans of $3 million. Adjusted results for the three months ended December 31, 2021 exclude net mark-to-market gains on restricted asbestos investments and pension and postretirements plans of $57 million.

(5) Adjusted results for the three months ended December 31, 2022 exclude restructuring and impairment costs of $345 million. These costs are related primarily to the impairment of assets associated with businesses classified as held for sale, workforce reductions and other related costs. Adjusted results for the three months ended December 31, 2021 exclude restructuring and impairment costs of $49 million. These costs are related primarily to workforce reductions and other related costs.

(6) Management defines earnings before interest and taxes (EBIT) as income before net financing charges, income taxes and noncontrolling interests. EBIT margin is defined as EBIT divided by net sales. EBIT and EBIT margin are non-GAAP performance measures. Management believes these non-GAAP measures are useful to investors in understanding the ongoing operations and business trends of the Company. A reconciliation of EBIT to net income is shown earlier within this footnote.

(7) Adjusted income tax provision for the three months ended December 31, 2022 excludes the net tax benefit of pre-tax adjusting items of $64 million. Adjusted income tax provision for the three months ended December 31, 2021 excludes the net tax expense of pre-tax adjusting items of $5 million.

(8) Adjusted income attributable to noncontrolling interests for the three months ended December 31, 2021 excludes $5 million impact from restructuring and impairment costs.

(9) Segment EBITA margin is defined as segment EBITA divided by segment net sales, as disclosed in the Company's press release.

(10) Adjusted segment EBITA for the three months ended December 31, 2022 excludes a $40 million uninsured loss attributable to a fire at a warehouse in Menominee, Michigan.

The Company's press release and earnings presentation include forward-looking statements regarding organic revenue growth, adjusted segment EBITA margin improvement, free cash flow and adjusted EPS, which are non-GAAP financial measures. These non-GAAP financial measures are derived by excluding certain amounts from the corresponding financial measures determined in accordance with GAAP. The determination of the amounts excluded is a matter of management judgment and depends upon, among other factors, the nature of the underlying expense or income amounts recognized in a given period and the high variability of certain amounts, such as mark-to-market adjustments. Organic revenue growth excludes the effect of acquisitions, divestitures and foreign currency. We are unable to present a quantitative reconciliation of the aforementioned forward-looking non-GAAP financial measures to their most directly comparable forward-looking GAAP financial measures because such information is not available, and management cannot reliably predict the necessary components of such GAAP measures without unreasonable effort or expense. The unavailable information could have a significant impact on the Company’s fiscal 2023 second quarter and full year GAAP financial results.

2. Diluted Earnings Per Share Reconciliation

The Company's press release contains financial information regarding adjusted earnings per share, which is a non-GAAP performance measure. The adjusting items shown in the table below are excluded because these items are not considered to be directly related to the underlying operating performance of the Company. Management believes this non-GAAP measure is useful to investors in understanding the ongoing operations and business trends of the Company.

4. Free Cash Flow Conversion

The Company's press release contains financial information regarding free cash flow and free cash flow conversion, which are non-GAAP performance measures. We also present below free cash flow conversion from the GAAP measure of net income attributable to JCI. Free cash flow is defined as cash provided by operating activities less capital expenditures. Free cash flow conversion from net income is defined as free cash flow divided by net income attributable to JCI. Free cash flow conversion is defined as free cash flow divided by adjusted net income attributable to JCI. Management believes these non-GAAP measures are useful to investors in understanding the strength of the Company and its ability to generate cash. These non-GAAP measures can also be used to evaluate our ability to generate cash flow from operations and the impact that this cash flow has on our liquidity.
