Management Commentary

"The second quarter marked an important milestone for AMASS and the beginning of a new chapter for the business," said Mark Thomas Lynn, Founder and Chief Executive Officer of AMASS. "We completed our Nasdaq listing, strengthened our capital structure and continued transforming AMASS into a more focused portfolio built around the brands and categories where we see the greatest long-term opportunity. Becoming a public company was an important step, but what matters most is building a business that can consistently create value over the long term, and we believe this quarter shows that strategy is beginning to take shape."

"The portfolio is changing exactly as we intended. Our four Core Brands, Summer Water, Pizzolato MUSE, Good Twin and AMASS Electrolytes, grew 12% and now account for 67% of brand-attributed revenue, up from 62% a year ago. At the same time, the brands we have intentionally exited or are winding down declined 27%. That's exactly the transition we set out to create. We aren't trying to operate the largest collection of beverage brands. We're concentrating our resources behind the brands where we see the strongest consumer demand, the greatest long-term potential and the best economics."

"We're also seeing encouraging validation across the portfolio. Pizzolato MUSE expanded nationally at Whole Foods Market and into Eataly, Good Twin continued its strong growth, and AMASS Electrolytes generated its first commercial revenue following its launch earlier this year. We also announced our planned acquisition of HpO, expanding our position in functional hydration. This is the platform working as designed: identifying categories where consumer behavior is changing, building or acquiring brands positioned to lead those categories, and leveraging our existing infrastructure to scale them more efficiently."

"Our consolidated financial results also reflect deliberate decisions we made during the quarter. We accelerated the sale of slower-moving inventory, accepted near-term margin pressure to simplify the portfolio and convert inventory into cash, and continued investing behind the brands driving our future growth. Those actions affected reported profitability in the short term, but we believe they leave the business in a stronger position as our sales mix continues shifting toward our higher-quality Core Brands."

"We still have important work ahead of us. Improving margins, strengthening our balance sheet and securing the capital necessary to execute our long-term plan remain our highest priorities. But as we look at the business today, we believe the underlying direction has never been clearer. We're building a simpler, more focused and more capital-efficient beverage company, and we believe we're still in the early stages of what this platform can become."

Outlook

As AMASS continues its transition to a more focused, growth-oriented beverage platform, the Company is introducing financial guidance for the first time as a public company. Management believes the progress made in simplifying the portfolio, expanding distribution of its Core Brands, and building its Non-Alcoholic and Functional business provides increasing visibility into the business and supports the outlook below.

Based on current trends and management's operating plan, the Company expects a return to year-over-year growth in the second half of fiscal 2026, with second-half net revenues of at least $8.7 million, representing growth of at least approximately 10% over second-half fiscal 2025:

Mr. Lynn commented, "We're introducing guidance because we believe the business has reached an important turning point. Our portfolio is becoming more focused, our Core Brands are driving a larger share of the business, and we have better visibility into the factors we believe will drive growth over the next several quarters. We've intentionally set our near-term outlook at levels we believe we can achieve while continuing to execute against our long-term strategy. Going forward, our objective is straightforward: build credibility by consistently doing what we say we're going to do."

This outlook reflects management’s current expectations and assumptions, including continued execution of the Company’s distribution expansion strategy, a stable input-cost and tariff environment, no material changes in distributor relationships, and no financing events that have not already closed. It does not assume, and should not be read to reflect, the outcome of the Company’s efforts to obtain the additional capital described above under “Liquidity and going concern.” These expectations are forward-looking statements subject to the risks described under “Forward-Looking Statements” below and in the Company’s filings with the SEC, and actual results may differ materially. The Company addresses its guidance only at scheduled earnings releases and undertakes no obligation to update it between them.

Non-GAAP Financial Information

This press release includes Adjusted EBITDA, adjusted gross profit and adjusted gross margin, financial measures that are not calculated in accordance with generally accepted accounting principles in the United States (“GAAP”). Management uses these measures to evaluate operating performance and allocate resources, and believes they assist investors in comparing operating performance across periods by removing items that are non-cash, non-recurring, or not indicative of ongoing operations. Adjusted EBITDA has limitations as an analytical tool: it excludes interest expense on indebtedness the Company is obligated to service, it excludes depreciation and amortization of assets that will need to be replaced, and other companies may calculate similarly titled measures differently, limiting comparability. These measures should be considered in addition to, and not as a substitute for or superior to, net loss, gross profit or any other measure determined in accordance with GAAP. A reconciliation of net loss, the most directly comparable GAAP measure, to Adjusted EBITDA, and of gross profit to adjusted gross profit, is included in the tables below.

Definitions

Adjusted EBITDA means net loss before interest, income taxes, depreciation and amortization, further adjusted for a fixed set of add-backs: one-off deal and direct-listing costs; stock-based compensation; stock-settled banker fees; impairment and bad debt, net; inventory write-downs and variance; juice storage; merchant and factoring fees; the net results of bulk wine and of the divested business unit; loss on contracts; and one-time credits, which are deducted. Recurring public-company operating costs — including annual exchange listing fees, directors’ and officers’ insurance, incremental headcount and ongoing investor-relations costs — are not added back and remain in Adjusted EBITDA.

Adjusted gross profit means gross profit adjusted for inventory write-downs and variance, net, and for the net results of bulk wine.
