FOR IMMEDIATE RELEASE

SLEEP NUMBER ANNOUNCES FOURTH QUARTER AND FULL YEAR 2023 RESULTS

•Fourth quarter net sales declined 14% versus the prior year with demand down low-single digits

•Full year diluted loss per share of $0.68; full year “as adjusted” loss per share of $0.14, excluding $16 million of restructuring costs recorded in the fourth quarter

•Reduced operating expenses by $85 million in 2023; expect a further expense reduction of $40 million to $45 million in 2024 for a two-year total reduction of approximately $130 million (before restructuring costs)

•Expect 2024 adjusted EBITDA of $125 million to $145 million

MINNEAPOLIS – (February 22, 2024) – Sleep Number Corporation (Nasdaq: SNBR) today reported results for the year ended December 30, 2023.

“While the consumer environment remains challenging for the mattress industry, our swift actions to improve demand and reduce costs allowed us to make better progress in the fourth quarter than we expected,” said Shelly Ibach, Chair, President and CEO. “Through broad-based restructuring actions to streamline our cost structure, restore margins and strengthen our balance sheet, we are transforming our operating model to improve our financial resilience and position our business for accelerating growth as the mattress industry demand environment improves. Importantly, our long-term opportunity remains intact as we lead through this transformation.”

Fourth Quarter Overview

•Net sales decreased 14% to $430 million, with demand down low-single digits year-over-year

•Gross margin of 56.6% was up 190 bp versus the prior year, primarily benefiting from pricing actions, easing commodity prices and operating cost reductions, partially offset by increased promotions

•Operating expenses were reduced by $24 million to $247 million (before restructuring charges) compared with $271 million last year

•Loss per diluted share of $1.12; “as adjusted” diluted loss per share of $0.58, excluding $16 million of restructuring costs recorded in the fourth quarter

Full Year Overview

•Net sales decreased 11% to $1.89 billion in 2023

•Gross margin increased to 57.7% of net sales, compared with 56.9% for the prior year, including the benefit of pricing actions, easing commodity prices and other cost reduction initiatives

•Loss per diluted share of $0.68; “as adjusted” diluted loss per share of $0.14, excluding $16 million of restructuring costs recorded in the fourth quarter

Cash Flows and Liquidity Review

•Net cash used in operating activities of $9 million, compared with $36 million of cash provided by operating activities last year

•Leverage ratio of 4.1x EBITDAR at the end of the fourth quarter versus covenant maximum of 5.0x

•Adjusted ROIC of 7.8% for the trailing twelve months

Business Restructuring Update

•The company’s broad-based cost management initiatives are progressing as planned. Operating expenses were reduced by $85 million in 2023, with $40 million to $45 million of additional operating expense reductions planned for 2024

•Reduced workforce to approximately 4,100 team members at end of 2023, 7% lower than 2019

•Expect specific ongoing workstreams including product value engineering, service simplification, streamlining suppliers and reprioritizing spend to accelerate near-term growth and efficiency

Financial Outlook

The company expects mattress industry demand to remain pressured in 2024. Against this backdrop, the company expects adjusted EBITDA of $125 million to $145 million in 2024, with net sales down mid-single digits versus prior year on a low-single digit demand decline. The company expects approximately 100 basis points of gross margin rate improvement and $12 million of restructuring charges for the year. The company expects to generate $60 million to $80 million of free cash flow with capital expenditures of $30 million.

Earnings before Interest, Taxes, Depreciation and Amortization (Adjusted EBITDA)

We define earnings before interest, taxes, depreciation and amortization (Adjusted EBITDA) as net income plus: income tax expense, interest expense, depreciation and amortization, stock-based compensation, restructuring costs and asset impairments. Management believes Adjusted EBITDA is a useful indicator of our financial performance and our ability to generate cash from operating activities. Our definition of Adjusted EBITDA may not be comparable to similarly titled definitions used by other companies. The table below reconciles Adjusted EBITDA, which is a non-GAAP financial measure, to the comparable GAAP financial measure:

Calculation of Return on Invested Capital (Adjusted ROIC)

(in thousands)

Adjusted ROIC is a financial measure we use to determine how efficiently we deploy our capital. It quantifies the return we earn on our adjusted invested capital. Management believes Adjusted ROIC is also a useful metric for investors and financial analysts. We compute Adjusted ROIC as outlined below. Our definition and calculation of Adjusted ROIC may not be comparable to similarly titled definitions and calculations used by other companies. The tables below reconcile adjusted net operating profit after taxes (Adjusted NOPAT) and total adjusted invested capital, which are non-GAAP financial measures, to the comparable GAAP financial measures:
