San Francisco, CA, May 28, 2020 – Williams-Sonoma, Inc. (NYSE: WSM) today announced operating results for the first fiscal quarter ended May 3, 2020 (“Q1 20”) versus the first fiscal quarter ended May 5, 2019 (“Q1 19”).

“As the COVID-19 health crisis continues to impact our daily lives, our deep gratitude goes to all of the people who are taking care of our communities in the fight against this pandemic. We also want to thank our associates for their agility, commitment and partnership in continuing to meet our customers’ needs while prioritizing the health and safety of each other, our customers and our communities,” said Laura Alber, President and Chief Executive Officer.

“In this highly disrupted environment, we are proud to deliver 2.6% comp growth in the first quarter, despite having all of our 616 stores closed for more than half of the quarter. Our large e-commerce business had breakout comp growth in the second half of the quarter and continues to accelerate. Our teams maximized demand online, leaning into new and innovative ways to engage and serve our customers virtually. We gained market share with strong new customer growth in our DTC business, giving us even more confidence in the growth trajectory of our e-commerce business longer term,” Alber continued. “The resilience of our business through this crisis exemplifies the advantage of our unique multi-brand, multi-channel platform and our commitment to all of our stakeholders. Nothing makes me prouder than to have achieved our results while staying true to our company’s core value of taking care of our people, customers and communities. Our strong financial position and fortress balance sheet have allowed us to support our associates with pay continuation, while giving back to support relief efforts in our local communities.”

Alber concluded, “Reflecting on the longer term, this crisis has accelerated our industry’s shift to e-commerce, and given rise to a newfound appreciation for the home. We believe that with our differentiated value proposition of sustainable, design-led products and a powerful digital first platform, we are well positioned.”

SEC REGULATION G — NON-GAAP INFORMATION

This press release includes non-GAAP financial measures. Exhibit 1 provides reconciliations of these non-GAAP financial measures to the most comparable financial measures calculated and presented in accordance with accounting principles generally accepted in the U.S. (“GAAP”). We have not provided a reconciliation of non-GAAP guidance measures to the corresponding GAAP measures on a forward-looking basis due to the potential variability and limited visibility of excluded items; these excluded items include expenses related to the acquisition and operations of Outward, Inc., employment-related expense, inventory-related charges and store asset impairments due to the impact of COVID-19. We believe that these non-GAAP financial measures, when reviewed in conjunction with GAAP financial measures, can provide meaningful supplemental information for investors regarding the performance of our business and facilitate a meaningful evaluation of current period performance on a comparable basis with prior periods. Our management uses these non-GAAP financial measures in order to have comparable financial results to analyze changes in our underlying

business from quarter to quarter. In addition, certain other items may be excluded from non-GAAP financial measures when the company believes this provides greater clarity to management and investors. These non-GAAP financial measures should be considered as a supplement to, and not as a substitute for or superior to the GAAP financial measures presented in this press release and our financial statements and other publicly filed reports. Non-GAAP measures as presented herein may not be comparable to similarly titled measures used by other companies.

SEC Regulation G – Non-GAAP Information

These tables include non-GAAP gross profit, gross margin, selling, general and administrative expense, operating income, operating margin, income taxes, effective tax rate and diluted EPS. We believe that these non-GAAP financial measures provide meaningful supplemental information for investors regarding the performance of our business and facilitate a meaningful evaluation of our quarterly actual results on a comparable basis with prior periods. Our management uses these non-GAAP financial measures in order to have comparable financial results to analyze changes in our underlying business from quarter to quarter. These non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP.

Notes to Exhibit 1:

Return on Invested Capital (“ROIC”)

We believe ROIC is a useful financial measure for investors in evaluating the efficient and effective use of capital, and is an important component of long-term shareholder return. We define ROIC as non-GAAP net operating profit after tax (NOPAT), divided by our average invested capital. NOPAT is defined as non-GAAP operating income, plus rent expense, less estimated taxes at the company’s effective tax rate. Average invested capital is defined as the two-year average of total assets less current liabilities, plus capitalized leases, less cash in excess of $200 million.

ROIC is not a measure of financial performance under GAAP, and should be considered in addition to, and not as a substitute for other financial measures prepared in accordance with GAAP. Our method of determining ROIC may differ from other companies’ methods and therefore may not be comparable.
