Guardian Pharmacy Services, Inc. Reports Third Quarter 2024 Financial Results

ATLANTA—(BUSINESS WIRE)— Guardian Pharmacy Services, Inc. (“Guardian”) (NYSE: GRDN), one of the nation’s largest long-term care (LTC) pharmacy services companies, today announced financial results for the third quarter ended September 30, 2024.

Third Quarter 2024 Highlights

Three Months Ended September 30, 2024

Nine Months Ended September 30, 2024

“After successfully completing our IPO in September, we are happy to report that our first quarter as a public company produced strong results and highlighted Guardian’s track record of consistent growth,” said Fred Burke, President & CEO of Guardian.

Mr. Burke added, “I am especially proud of our team and how impressively they navigated the challenges surrounding Hurricane Helene in the third quarter, helping to ensure that all residents served by Guardian impacted by the storm would continue to have access to medications. Heartland, a larger acquisition completed in Q2 that added four new locations and 8,600 residents in the Intermountain West, has continued to progress in implementing the Guardian platform. While it is typically a 2 to 3 year process for our acquired locations to fully come up to speed, we are encouraged by early results.

As we look forward, we just completed an acquisition which takes us to an attractive, new market; while smaller in size it has a great operating team which we can leverage for future growth. We expect to end this year on solid footing, setting a steady foundation for continued growth.We have more than 230 employee owners excited to take us forward as a public company.”

Initial 2024 Full Year Guidance

For the full year, Guardian is providing the following guidance:

Guardian has not provided a quantitative reconciliation of forecasted Adjusted EBITDA, a non-GAAP financial measure to forecasted net income within this communication because Guardian is unable, without making unreasonable efforts, to calculate certain reconciling items with confidence due to the variability and complexity of such items. These items include, but are not limited to, income taxes and share-based compensation. These items, which could materially affect the computation of forecasted net income, are inherently uncertain and depend on various factors, many of which are outside of Guardian’s control.

Guardian will host a conference call to discuss its third quarter 2024 financial results later today, Tuesday, November 12, 2024, at 4:30 p.m. ET. The conference call can also be accessed by dialing (800) 245-3047 for U.S. participants, or (203) 518-9765 for international participants, and referencing conference ID “Guardian.” A replay will be available online at https:/investors.guardianpharmacy.com shortly after the call’s completion and will remain available for approximately 60 days.

Forward-Looking Statements

This press release contains forward-looking statements. Forward-looking statements are all statements other than those of historical fact. Any statements about our expectations, beliefs, plans, predictions, forecasts, objectives, assumptions, or future events or performance are forward-looking. These statements are often, but not always, made through the use of words such as “aims,” “anticipates,” “believes,” “continue,” “estimates,” “expects,” “intends,” “may,” “outlook,” “plans,” “projects,” “seeks,” “should,” “will,” “would,” and similar expressions. Although we believe that the expectations reflected in these forward-looking statements are reasonable, these statements are not guarantees of future performance and involve risks and uncertainties which are subject to change based on various important factors, some of which are beyond our control. Such risks and uncertainties include: our ability to effectively execute our business strategies, implement new initiatives and improve efficiency; our ability to effectively market and sell, customer acceptance of, and competition for, our

pharmaceutical services in new and existing markets; our relationships with pharmaceutical wholesalers and key manufacturers, LTCFs and health plan payors; our ability to maintain and expand relationships with LTCF operators on favorable terms; the impact of the outbreak of a national emergency, public health crisis or global pandemic, such as COVID-19, on our employees and business and on our supply chain and the LTCFs we serve; continuing government and private efforts to lower pharmaceutical costs, including by limiting pharmacy reimbursements; changes in, and our ability to comply with, healthcare laws, regulations or interpretations; further consolidation of managed care organizations and other health plan payors and changes in the terms of our agreements with these parties; our ability to retain members of our senior management team, our local pharmacy management teams and our pharmacy professionals; our exposure to, and the results of, claims, legal proceedings and governmental inquiries; our ability to maintain the security of our operating and information technology systems and infrastructure (e.g., against cyber-attacks); product liability, product recall, personal injury or other health and safety issues related to the pharmaceuticals we dispense; supply chain and other manufacturing disruptions related to the pharmaceuticals we dispense; the sufficiency of our existing cash and cash equivalents to fund our future operating expenses and capital expenditure requirements, and our ability to raise additional capital, if needed; and the misuse or off-label use, or errors in the dispensing or administration, of the pharmaceuticals we dispense. We are subject to additional risks and uncertainties described in our periodic reports filed with the Securities and Exchange Commission from time to time, including in the “Risk Factors,” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections contained in our most recent Quarterly Report on Form 10-Q, which reports are made publicly available at www.sec.gov and via our website, investors.guardianpharmacy.com Any forward-looking statements in this press release should be evaluated in light of these important risk factors. This press release reflects management’s views as of the date hereof. Except to the extent required by applicable law, Guardian undertakes no obligation to update or revise any information contained in this press release beyond the published date, whether as a result of new information, future events or otherwise.

Use of Non-GAAP Financial Measures

To supplement our results prepared in accordance with generally accepted accounting principles in the United States (“GAAP”), we also present Adjusted EBITDA and Adjusted SG&A, which are non-GAAP financial measures. We define Adjusted EBITDA as net income (loss) before interest expense, income taxes, depreciation and amortization, as adjusted to exclude the impact of items and amounts that we view as not indicative of our core operating performance, including share-based compensation, acquisition accounting adjustments, and certain legal and regulatory items. We define Adjusted SG&A as GAAP selling, general, and administrative expenses adjusted to exclude the impact of share-based compensation and expenses relating to certain legal and regulatory items. Adjusted EBITDA and Adjusted SG&A do not have a definition under GAAP, and our definition of Adjusted EBITDA and Adjusted SG&A may not be the same as, or comparable to, similarly titled measures used by other companies.

We use Adjusted EBITDA and Adjusted SG&A to better understand and evaluate our core operating performance and trends. We believe that presenting Adjusted EBITDA and Adjusted SG&A provides useful information to investors in understanding and evaluating our operating results, as it permits investors to view our core business performance using the same metrics that management uses to evaluate our performance.

There are a number of limitations related to the use of Adjusted EBITDA and Adjusted SG&A rather than the most directly comparable GAAP financial measure, including:

Because of these limitations, Adjusted EBITDA and Adjusted SG&A should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. You should consider Adjusted EBITDA and Adjusted SG&A alongside other financial measures, including net income, GAAP selling, general, and administrative expense and our other financial results presented in accordance with GAAP. For a reconciliation of Adjusted EBITDA to net income, and Adjusted SG&A to GAAP selling, general, and administrative expense, for the historical periods presented herein, please see the reconciliation tables below.
