Safe Harbor Statement and Non-GAAP Financial Measures

All statements in this communication, other than those relating to historical facts, are "forward-looking statements." Forward-looking statements can generally be identified by their use of terms such as "anticipate," "estimate," "believe," "expect," "could," "forecast," "may," "intend," "plan," "predict," "project," "will," or "would," and similar terms and phrases, including references to assumptions. Forward-looking statements are not guarantees of future performance and are subject to a number of assumptions, risks and uncertainties, many of which are beyond our control, which could cause actual results to differ materially from such statements. Forward-looking statements include, but are not limited to, statements about future strategic plans and future financial and operating results. Important factors that could cause actual results to differ materially from those presented or implied in the forward-looking statements include, without limitation: inflation, higher product costs or other expenses, including operational and administrative expenses; the impact of macroeconomic pressures and geopolitical trends, changes and events; a major loss of customers; loss or disruption of sources of supply; changes in customer or product mix; increased competitive pricing pressures; changes in third party practices regarding digital advertising; failure to enter into or sustain contractual arrangements on a satisfactory basis with group purchasing organizations; failure to develop, manage or implement new technology initiatives or business strategies, including with respect to Grainger's eCommerce platforms; failure to adequately protect intellectual property or successfully defend against infringement claims; fluctuations or declines in Grainger's gross profit margin; Grainger's responses to market pressures; the outcome of pending and future litigation or governmental or regulatory proceedings, including with respect to wage and hour, anti-bribery and corruption, environmental, regulations related to advertising, marketing and the Internet, consumer protection, pricing (including disaster or emergency declaration pricing statutes), product liability, compliance or safety, trade and export compliance, general commercial disputes, or privacy and cybersecurity matters; investigations, inquiries, audits and changes in laws and regulations; failure to comply with laws, regulations and standards, including new or stricter environmental laws or regulations; government contract matters; the impact of any government shutdown; disruption or breaches of information technology or data security systems involving Grainger or third parties on which Grainger depends; general industry, economic, market or political conditions; general global economic conditions including tariffs and trade issues and policies; currency exchange rate fluctuations; market volatility, including price and trading volume volatility or price declines of Grainger's common stock; commodity price volatility; facilities disruptions or shutdowns; higher fuel costs or disruptions in transportation services; outbreaks of pandemic disease or viral contagions; natural or human induced disasters, extreme weather and other catastrophes or conditions; effects of climate change; failure to execute on our efforts and programs related to environmental, social and governance matters; competition for, or failure to attract, retain, train, motivate and develop executives and key employees; loss of key members of management or key employees; loss of operational flexibility and potential for work stoppages or slowdowns if employees unionize or join a collective bargaining arrangement; changes in effective tax rates; changes in credit ratings or outlook; Grainger's incurrence of indebtedness or failure to comply with restrictions and obligations under its debt agreements and instruments; and other factors that can be found in our filings with the Securities and Exchange Commission, including our most recent periodic reports filed on Form 10-K and Form 10-Q, which are available on our Investor Relations website. Forward-looking statements are given only as of the date of this communication and we disclaim any obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law.

Additional information relating to certain non-GAAP financial measures referred to in this presentation is available in the appendix to this presentation, including: adjusted return on invested capital; adjusted gross profit, adjusted operating earnings, adjusted EBITDA; adjusted SG&A; daily sales; daily, organic daily sales; constant currency sales; daily, organic constant currency sales; constant currency sales in local days; daily, organic constant currency sales in local days; net leverage ratio; and free cash flow. This communication also includes certain non-GAAPforward-looking information (including, but not limited to slides 25-26 & 33 - 35). The Company believes that a quantitative reconciliation of such forward-looking information to the most comparable financial measure calculated and presented in accordance with GAAP cannot be made available without unreasonable efforts. A reconciliation of these non-GAAP financial measures would require the Company to predict the timing and likelihood of future restructurings, asset impairments, and other charges. Neither these forward-looking measures, nor their probable significance, can be quantified with a reasonable degree of accuracy. Accordingly, the most directly comparable forward-looking GAAP measures are not provided. Forward-lookingnon-GAAP financial measures provided without the most directly comparable GAAP financial measures may vary materially from the corresponding GAAP financial measures.
