Discussion of First Quarter Results

All comparisons are to the prior year period unless otherwise noted

• Revenue grew by 9 percent on a constant currency basis, driven by increased demand for our sleep and respiratory care devices as well as reduced competitive supply.

• Revenue in the U.S., Canada, and Latin America, excluding Software-as-a-Service, grew by 18 percent, primarily due to the factors discussed above and recovery of core sleep patient flow that was previously impacted by COVID-19.

• Revenue in Europe, Asia, and other markets declined by 6 percent on a constant currency basis.

• Software-as-a-Service revenue increased by 9 percent, due to continued growth in our Home Medical Equipment vertical.

• Gross margin increased by 90 basis points and non-GAAP gross margin increased by 40 basis points, mainly due to an increase in average selling prices, partially offset by unfavorable product mix and foreign currency movements.

• Selling, general, and administrative expenses increased by 16 percent on a constant currency basis. SG&A expenses increased to 20.4 percent of revenue in the quarter, compared with 19.5 percent in the same period of the prior year. These changes in SG&A expenses were mainly due to increases in employee-related expenses and increases in travel expenses.

• Income from operations increased by 5 percent and non-GAAP income from operations increased by 4 percent.

RMD First Quarter 2023 Earnings Press Release – October 27, 2022 Page 3 of 10

• Net income for the quarter was $210.5 million and diluted earnings per share was $1.43. Non-GAAP net income was $222.1 million, and non-GAAP diluted earnings per share was $1.51, both consistent with the same period of the prior year.

• Operating cash flow for the quarter was $44.7 million, reflecting the impact of increases in working capital. During the quarter we paid $64.4 million in dividends.

Other Business and Operational Highlights

• Announced the acquisition of mementor, a German pioneer and health tech startup that develops and distributes digital medical products in the field of sleep medicine and related areas. mementor offers the first permanently approved Digital Health Application (DiGA), somnio, eligible for reimbursement in the field of sleep medicine.

• Celebrated the official opening of ResMed’s new technology R&D facility in Ireland (Sandyford in Dublin) and announced a plan to double the Ireland-based software and technology team with 70 jobs over the next four years to support innovation, technology development, and product development.

• Released updated global chronic obstructive pulmonary disease (COPD) prevalence numbers via a late-breaking abstract at the European Respiratory Society Congress. Based on ResMed’s updated research, it’s estimated over 480 million people worldwide suffer from COPD, a 22-126% increase over today’s most cited resources.

Dividend program

The ResMed board of directors today declared a quarterly cash dividend of $0.44 per share. The dividend will have a record date of November 10, 2022, payable on December 15, 2022. The dividend will be paid in U.S. currency to holders of ResMed’s common stock trading on the New York Stock Exchange. Holders of CHESS Depositary Interests (“CDIs”) trading on the Australian Securities Exchange will receive an equivalent amount in Australian currency, based on the exchange rate on the record date, and reflecting the 10:1 ratio between CDIs and NYSE shares. The ex-dividend date will be November 9, 2022, for common stockholders and for CDI holders. ResMed has received a waiver from the ASX’s settlement operating rules, which will allow ResMed to defer processing conversions between its common stock and CDI registers from November 9, 2022, through November 10, 2022, inclusive.

Reconciliation of Non-GAAP Financial Measures

(Unaudited; $ in thousands, except for per share amounts)

The measures “non-GAAP net income” and “non-GAAP diluted earnings per share” are reconciled with GAAP net income and GAAP diluted earnings per share in the table below:

	Three Months Ended
	September 30, 2022		September 30, 2021
GAAP net income	$	210,478	$	203,613
Amortization of acquired intangibles—cost of sales, net of tax (A)		4,835		8,435
Amortization of acquired intangibles—operating expenses, net of tax (A)		6,031		5,878
Acquisition-related expenses (A)		745		—
Reserve for disputed tax position (A)		—		4,111
Non-GAAP net income (A)	$	222,089	$	222,037
GAAP diluted shares outstanding		147,134		146,860
GAAP diluted earnings per share	$	1.43	$	1.39
Non-GAAP diluted earnings per share (A)	$	1.51	$	1.51

(A) ResMed adjusts for the impact of the amortization of acquired intangibles, acquisition-related expenses and the reserve for disputed tax positions from their evaluation of ongoing operations, and believes that investors benefit from adjusting these items to facilitate a more meaningful evaluation of current operating performance.

ResMed believes that non-GAAP diluted earnings per share is an additional measure of performance that investors can use to compare operating results between reporting periods. ResMed uses non-GAAP information internally in planning, forecasting, and evaluating the results of operations in the current period and in comparing it to past periods. ResMed believes this information provides investors better insight when evaluating ResMed’s performance from core operations and provides consistent financial reporting. The use of non-GAAP measures is intended to supplement, and not to replace, the presentation of net income and other GAAP measures. Like all non-GAAP measures, non-GAAP earnings are subject to inherent limitations because they do not include all the expenses that must be included under GAAP.
