NEW YORK, N.Y., November 14, 2023 – The Cannabist Company Holdings Inc.

All financial information presented in this release is in U.S. GAAP and in thousands of U.S. dollars, unless otherwise noted.

Third Quarter 2023 U.S. GAAP Financial Highlights (in $ thousands, excl. margin items):

“The third quarter results demonstrate consistent execution, with stable revenue of more than $129 million and Adjusted EBITDA of more than $20 million, in a complicated quarter rife with corporate actions and changes to the business reflecting our first independent partial quarter,” said Nicholas Vita, CEO of The Cannabist Company. “In July, we announced the mutual agreement to terminate the pending merger agreement after 16 months, and immediately announced corporate restructuring and operational changes to launch the Company into our next chapter, focused on resetting manufacturing priorities, managing the balance sheet, and beginning the process of restructuring elements of COGS to drive gross margin improvement in 2024. Less than two months later, we announced the transition from Columbia Care to The Cannabist Company, which is a reflection of where our organization and the market are heading, as we continue to innovate and differentiate in an ever-evolving industry”.

He continued, “As we continue to optimize our footprint and prioritize markets that are driving profitability and growth, we are preparing to capitalize on the embedded growth in our portfolio, with additional retail locations expected to open in Maryland, New Jersey, New York, Ohio, and Virginia beginning in 2024. We are also growing the wholesale program and are targeting enhanced margin through increased facility utilization and greater branded product sales. We will continue to make progress, as we did in the third quarter, toward proactively managing our balance sheet and improving liquidity. We are excited for the road ahead as The Cannabist Company and look forward to providing updates on our progress.”

Non-GAAP Financial Measures

In this press release, The Cannabist Company refers to certain non-GAAP financial measures, including Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Gross Profit and Adjusted Gross Margin. The Cannabist Company considers certain non-GAAP measures to be meaningful indicators of the performance of its business. These measures are not recognized measures under GAAP, do not have a standardized meaning prescribed by GAAP and may not be comparable to (and may be calculated differently by) other companies that present similar measures. Accordingly, these measures should not be considered in isolation from nor as a substitute for our financial information reported under GAAP. These non-GAAP measures are used to provide investors with supplemental measures of our operating performance and thus highlight trends in our business that may not otherwise be apparent when relying solely on GAAP measures. These supplemental non-GAAP financial measures should not be considered superior to, as a substitute for, or as an alternative to, and should be considered in conjunction with, the GAAP financial measures presented. We also recognize that securities analysts, investors and other interested parties frequently use non-GAAP measures in the evaluation of companies within our industry.

With respect to non-GAAP financial measures, the Company defines EBITDA as net income (loss) before (i) depreciation and amortization; (ii) income taxes; and (iii) interest expense and debt amortization. Adjusted EBITDA is defined as EBITDA before (i) share-based compensation expense; (ii) goodwill and intangible impairment, (iii) adjustments for acquisition and other non-core costs; (iv) gain on remeasurement of contingent consideration, net, (v) fair value changes on derivative liabilities; and (vi) fair value mark-up for acquired inventory. Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by Revenue. Adjusted Gross Profit is defined as gross profit before the fair mark-up for acquired inventory. Adjusted Gross Margin is defined as gross margin before the fair mark-up for acquired inventory.

The Company views these non-GAAP financial measures as a means to facilitate management’s financial and operational decision-making, including evaluation of the Company’s historical operating results and comparison to competitors’ operating results. These non-GAAP financial measures reflect an additional way of viewing aspects of the Company’s operations that, when viewed with GAAP results and the reconciliations to the corresponding GAAP financial measure, may provide a more complete understanding of factors and trends affecting the Company’s business. The determination of the amounts that are excluded from these non-GAAP financial measures are a matter of management judgment and depend upon, among other factors, the nature of the underlying expense or income amounts. Because non-GAAP financial measures exclude the effect of items that will increase or decrease the Company’s reported results of operations, management strongly encourages investors to review the Company’s consolidated financial statements and publicly filed reports in their entirety.

Reconciliations of non-GAAP financial measures to their nearest comparable GAAP measures are included in this press release and a further discussion of some of these items will be contained in our quarterly report on Form 10-Q.
