GREENSBORO, NC - November 2, 2026 - Guerrilla RF, Inc. (OTCQX: GUER) (“Guerrilla RF” or the “Company”), a leading provider of high-performance RF and microwave semiconductors, today reported record financial results for the third quarter ended September 30, 2026. A recorded webcast of management’s commentary reviewing the Q3 2026 financial results and an update on the business will be available on the Company’s website today, November 2, 2026 (see details below).

“Our record third-quarter results reflect strong momentum with our growth and profitability initiatives that are driving consistent increases in revenue, operating income and margins and cash flow,” said Ryan Pratt, Founder and CEO of Guerrilla RF. “Third quarter revenue increased 61% year over year to $10.1 million, gross margin expanded approximately 416 basis points to 71.7%, and Adjusted EBITDA increased to $2.9 million from $0.3 million in the prior-year quarter. The significant momentum in our business is also demonstrated by our record quarter-end product backlog of $16.2 million.

“Aerospace and Defense continues to be a standout market for the Company, as revenues from this market grew 259% year over year and represented approximately 40% of total revenue in the quarter, up from 18% in the prior year period and 28% in the 2026 second quarter. Demand across drone, satellite communications and tactical communications programs continues to drive our growing penetration of this market. In addition, our continued innovation in gallium nitride (GaN) technology is opening up another attractive growth channel for Guerrilla RF as we expect our growing GaN portfolio to become an increasingly meaningful contributor to revenue beginning in 2027. Given the breadth of the growth opportunities we are executing against, we entered the fourth quarter with increasing confidence in our ability to sustain high-margin growth and increasing cash generation going forward.”

Third Quarter 2026 Business Highlights

¹ Beginning in the third quarter of 2026, the Company began presenting Aerospace and Defense as a separate market category due to its increased significance. Previously, Aerospace and Defense was included within the Catalog market category. Accordingly, prior-period market revenue information has been recast to conform to the current presentation.

Third Quarter 2026 Financial Highlights

“Our third quarter results demonstrate the operating leverage and scalability of our model, with significant revenue growth translating into strong operating income and Adjusted EBITDA,” said Mike John-Williams, CFO of Guerrilla RF. “We have increasing confidence that, as we scale, revenue can continue to grow faster than the cost base required to support that growth. As a result, we expect a meaningful share of incremental revenue to convert into higher earnings and cash flow. We believe this positions us to increasingly fund our product roadmap and continued expansion in Aerospace and Defense from internally generated cash while continuing to strengthen the balance sheet.”

Revenue

Revenue for the third quarter of 2026 increased 61% to $10.1 million, compared with $6.3 million in the prior-year period, establishing a new quarterly record for the Company. Growth was led by the Company’s Aerospace and Defense market category, where revenue increased approximately 259%, driven by higher demand across unmanned aerial systems, tactical communications and satellite communications applications. Catalog revenue increased approximately 32%, reflecting increased demand across a broad range of applications, while Infrastructure revenue increased approximately 78% to $1.4 million. These increases more than offset an approximately 9% decrease in Automotive revenue to $2.1 million.

Gross Profit and Margins

Gross profit increased 70% to $7.2 million, compared with $4.2 million in the prior-year period. Gross margin expanded to 71.7%, an improvement of approximately 416 basis points year over year, driven primarily by fixed overhead leverage on higher revenue and a favorable shift in product mix toward higher margin products and end markets.

Operating Expenses and Operating Performance

Total operating expenses increased 8% to $4.8 million, compared with $4.4 million in the prior year period, primarily reflecting continued investment in product development and higher travel and customer engagement costs to support increased sales activity. As a percentage of revenue, operating expenses declined to approximately 48% from approximately 71% in the prior-year period.

Operating income was $2.4 million, compared with an operating loss of $0.2 million in the third quarter of 2025, a $2.6 million improvement over the prior-year period. Operating margin improved to 24.1% from (3.2%) in the prior-year period.

Adjusted EBITDA

Adjusted EBITDA was $2.9 million, or 28.5% of revenue, in the third quarter of 2026, compared with $0.3 million, or 4.3% of revenue, in the prior-year period, and $1.5 million, or 19.2% of revenue, in the second quarter of 2026. The increase reflects improved operating leverage, as revenue growth and higher gross margins more than offset the increase in operating expenses.

Net Loss

Net loss for the third quarter of 2026 was $(3.7) million, compared with a net loss of $(0.6) million in the prior-year period. The 2026 result included a $(6.0) million non-cash loss from the change in fair value of warrant liabilities, compared with a $(0.2) million non-cash loss from the same item in the prior year period. Earnings per share were $(0.35) compared with $(0.06) in the prior-year period.

Cash Flow and Liquidity

Net operating cash flow was $2.3 million in the third quarter of 2026, compared with $0.9 million in the prior-year period. Guerrilla RF ended the quarter with $6.3 million in cash, up from $4.6 million on June 30, 2026.

Uplisting Update

Guerrilla RF continues to pursue an uplisting to the Nasdaq Stock Market as part of its strategy to broaden investor access and enhance its capital markets profile. Any uplisting remains subject to satisfaction of applicable listing requirements, Nasdaq approval and market conditions, and there can be no assurance that an uplisting will be completed.

Key Metrics (Non-GAAP Measures)

These non-GAAP measures have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of Company results as reported under GAAP. The Company compensates for such limitations by relying primarily on GAAP results and using non-GAAP measures only as supplemental data. In addition, because these non-GAAP measures are not measures of financial performance under GAAP and are susceptible to varying calculations, these measures, as defined by us, may differ from and may not be comparable to similarly titled measures used by other companies.

We regularly review the following key metrics to measure our performance, identify trends affecting our business, formulate financial projections, make strategic business decisions, and assess working capital needs.

Number of products released: The total number of distinct new products released into production (products that have completed design, quality, and supply chain readiness) during the period.

Number of total products: The cumulative number of production-released products since our inception through the end of the period.

Number of products with lifetime revenue exceeding $100 thousand: The number of products that have achieved the threshold of cumulative sales of $100,000 since our inception through the end of the period.

Product backlog: The amount of product sales that have been committed to by customers, but have not yet been completed, shipped, or invoiced as of the end of the period. The Company's product backlog can be materially impacted by supply chain constraints, a shift in customer ordering patterns whereby customers place orders in anticipation of extended product delivery lead times, or other customer order delivery request modifications. Furthermore, because the Company partners closely with a number of its customers to produce high-performance, quality components that are often designed into customers’ end products, immediate substitution of the Company’s products is neither typically desired by customers nor necessarily feasible. As such, the Company has not historically experienced significant order cancellations, and the Company does not expect significant order cancellations in the future. The Company closely monitors product backlog and its potential impact on the Company’s financial performance.

Adjusted EBITDA: The Company defines Adjusted EBITDA as net loss before interest expense (net of interest income), income taxes, depreciation and amortization, share-based compensation, the change in fair value of warrant liabilities and other income (expense). Management believes Adjusted EBITDA provides useful supplemental information about the Company’s operating performance by excluding non-cash and non-operating items, including the remeasurement of warrant liabilities, that can vary significantly from period to period. Adjusted EBITDA should be considered in addition to, and not as a substitute for, net loss or other measures prepared in accordance with GAAP. A table reconciling net loss, the most directly comparable GAAP measure, to Adjusted EBITDA is available on the last page of this press release.

Full financial details can be found in the Company’s 10-Q filed with the Securities and Exchange Commission.
