Grown Rogue Reports Third Quarter 2026 Results

Steady Execution Across Existing and New Markets; 2026 and 2027 Guidance and Growth Targets Maintained

MEDFORD, Ore., Nov. 12, 2026 /CNW/ - Grown Rogue International Inc. ("Grown Rogue," "we," "us," "our," or the "Company") (CSE: GRIN) (OTC: GRUSF), a flower-forward cannabis company combining craft values with disciplined execution, today reported its unaudited financial results for the three and nine months ended September 30, 2026.

Results are presented in U.S. dollars and in accordance with U.S. generally accepted accounting principles ("GAAP"). Comparative periods have been recast, where applicable, in accordance with GAAP.

Obie Strickler, Chief Executive Officer, said: "For us, it always comes back to the people buying what we make. They're spending their hard-earned money and trusting us to deliver products worth coming back for. We take that responsibility seriously, and as we grow, so does our commitment to getting it consistently right. I'm incredibly proud of how our team has maintained that focus while bringing several new markets online simultaneously. We've welcomed talented new people who are working alongside our existing team, bringing fresh perspectives to our deep operational experience. This combination gives me tremendous confidence in our ability to execute on our ambitious growth plans."

Highlights

Management Commentary and Outlook

"New Jersey had another strong quarter, with the consistent sell-through of branded, packaged products at attractive pricing demonstrating our ability to resonate with customers, and continued progress in our quality and efficiency KPIs," said Obie Strickler. "We're excited to have plants growing in Minnesota, with our first harvest in late November, and our first branded flower already on the shelves in Illinois. Entering a market is just the beginning. The real work now begins to earn the trust and respect of customers by making sure our passion and relentless focus on quality products shine through.

"Oregon and Michigan remain foundational markets for honing our operations and developing our talent. I'm really pleased with the progress these teams are making in improving yields and bringing costs down, while building bench strength and finding better ways of working that carry across our markets. They keep raising the bar for what I think is possible in efficiency and quality."

Josh Rosen, Chief Strategy Officer, added: "Two years ago, we believed that increasing distress in some corners of the cannabis industry would create significant opportunities for companies positioned to act. Since then, we've strengthened Grown Rogue with supportive capital and additional talent, building an organization ready for greater scale. Those opportunities have now materialized, with our announced plans to enter New York the largest to date."

"Our focus remains on execution. In New York specifically, PCNY's existing infrastructure gives us a substantial foundation, and I'm pleased with how quickly our team and the local PCNY team have mobilized to restart cultivation and re-energize the dispensaries. We anticipate PCNY should be back in the wholesale market in early 2027 and we are working diligently to support the execution of the purchase agreements and regulatory approvals needed to close these transactions."

Andrew Marchington, Chief Financial Officer, said: "The $5.0 million loss on the acquisition of Rogue EBC reflects the accounting impact associated with that transaction following our decision to pursue the existing turnkey Dwight facility rather than build a new facility in Waukegan. We are in discussions to offset some of our ongoing Rogue EBC obligations."

He added: "We're expanding our finance and support teams alongside our operating footprint, particularly to manage the increased work coming from our New York efforts. The New York transaction will add complexity to our fourth quarter and year-end closing and audit process. Assuming we execute the definitive purchase agreements in the fourth quarter, we anticipate the need to consolidate PCNY's results beginning on the date of the executed purchase agreements.  PCNY's corporate parent has been liquidating assets for more than a year and we anticipate the combination of headcount attrition and liquidity constraints may impact their ability to support our back-office integration and transition priorities, including our audit, and we are proactively preparing for these challenges."

Third Quarter Operating Update

New Jersey revenue was $4.9 million and Adjusted EBITDA was $2.4 million, up 44% and 65%, respectively, from the third quarter of 2025. Compared with the second quarter of 2026, total flower yield increased to 63 grams per square foot from 61, and "A" flower yield increased to 45 grams per square foot from 41. Phase II construction continued toward approximately 16,000 square feet of total flowering canopy, with substantial completion targeted by year-end and additional capacity expected to contribute more significantly to sales in 2027.

As anticipated, Oregon and Michigan remained highly price-competitive. Compared with the second quarter, total flower yield increased to 85 grams per square foot from 76 in Oregon and to 93 from 90 in Michigan. Cost per pound declined to $284 from $326 in Oregon and to $255 from $277 in Michigan. These improvements supported operating efficiency and informed practices across the broader organization, although pricing continued to weigh on financial performance.

In Minnesota, cultivation began at our Fridley facility following approval to operate. Phase I includes approximately 8,000 square feet of flowering canopy across five constructed flower rooms, being populated sequentially. The first harvest is anticipated in late November, with harvests every two weeks thereafter and first sales expected in January 2027.

New York Transaction Update

In August 2026, Grown Rogue established its 51%-owned subsidiary, GRNY, and entered into financing, consulting, lease and funding arrangements supporting the planned acquisition of PharmaCann's New York license and most of its assets. The planned transaction includes the Hamptonburgh cultivation and manufacturing facility and four Verilife dispensaries.

Under the Goods and Services Agreement ("GSA") executed on August 20, 2026, GRNY began supporting the operating transition, including the revitalization of cultivation at Hamptonburgh. The first harvest is anticipated in December 2026. Immediate priorities include establishing consistent cultivation performance and re-energizing the existing retail business following several months of heavy promotional and product liquidation activity.

A capital partner invested $10 million for a 49% preferred equity interest in GRNY and committed an additional $5 million drawable term loan. At announcement, estimated project costs, including the acquisition, capital expenditures and working capital, were approximately $12 million. A secured funding facility of up to $9 million from GRNY to PCNY supports the transition.

Subsequent Events

The following developments occurred after September 30, 2026.

New Jersey ownership: On October 20, 2026, the Company announced completion of its second option exercise, increasing its ownership of ABCO Garden State, LLC ("ABCO") by 26% to 70% and obtaining majority board control. Regulatory approval was received on September 16, 2026. The approximately $743,000 consideration had been advanced in 2023.

Illinois first sales: On October 22, 2026, the Company announced that affiliate SEA Craft LLC ("SEA Craft") had completed its first deliveries of Grown Rogue products to select Illinois dispensaries that week. Initial flowering canopy comprises approximately 5,000 square feet, with initial expansion work toward approximately 10,000 square feet underway. The pace of additional capacity will be informed by operating performance and market demand, subject to applicable regulatory requirements.

Operating KPIs by Market

Selected Quarterly Financial Results (Unaudited)

Selected Quarterly Financial Results by Segment (Unaudited)

Guidance and Long Term Growth Objectives

The Company is maintaining its previously announced 2026 and 2027 revenue and Adjusted EBITDA guidance and long-term growth objectives, with a reminder that the fourth quarter is typically seasonally slower than the third quarter. These expectations exclude New York. Management plans to revisit the outlook to incorporate New York when reporting fourth quarter and full year 2026 results.

The Company's three-to-five-year objectives, using 2027 as the base year, remain 25% annual compounded revenue growth, 35% annual compounded Adjusted EBITDA growth and return on incremental invested capital ("ROIIC") greater than 75%.

Grown Rogue's growth approach combines selective new builds, the revitalization of existing facilities and focused expansion of flower-forward products. Management evaluates opportunities using normalized market pricing and disciplined capital-allocation criteria.

Guidance Assumptions

The outlook continues to reflect Illinois sales beginning in Q4 2026, Minnesota first revenue in Q1 2027 and a greater contribution from New Jersey's Phase II expansion in 2027. Adjusted EBITDA guidance excludes pre-revenue startup expenses associated with new-market expansion, estimated at $1.5 million to $2.0 million in each of Illinois and Minnesota for 2026.

The previously disclosed 2027 framework assumes wholesale price normalization of approximately 10% in New Jersey and 5% in Illinois, no change in the Oregon and Michigan pricing environment, and Minnesota "A" flower wholesale pricing above $2,500 per pound. It also assumes continued capacity expansion in Illinois and Minnesota.

Non GAAP Financial Measures

This press release presents certain financial measures that are not calculated in accordance with United States generally accepted accounting principles ("GAAP"), including EBITDA, Adjusted EBITDA, Adjusted EBITDA margin and return on incremental invested capital ("ROIIC"). These non-GAAP financial measures do not have standardized meanings prescribed by GAAP and may not be comparable with similarly titled measures presented by other companies.

Management uses these non-GAAP financial measures as supplemental tools to evaluate the Company's underlying operating performance, compare results between periods and markets, and assess capital-allocation decisions. These measures should not be considered in isolation or as a substitute for, or superior to, financial measures prepared in accordance with GAAP.

EBITDA is defined as net income (loss) before interest and accretion expense, income tax expense, and depreciation and amortization, including amortization in cost of sales. Adjusted EBITDA further adjusts EBITDA for share-based compensation, derivative gains and losses, interest and other income (expense), changes in the fair value of warrant assets and liabilities, the loss on acquisition of Rogue EBC, losses on equity investments in associates, the GAAP bad debt conversion adjustment, Golden Harvests acquisition costs and pre-operational startup costs, as applicable and as presented in the reconciliation schedule.

Adjusted EBITDA margin is calculated as Adjusted EBITDA divided by the corresponding revenue measure. ROIIC is defined as the change in operating profit divided by the change in invested capital over the relevant measurement period.

Reconciliations of historical non-GAAP financial measures to the most directly comparable GAAP measures are included in the accompanying schedules.
