Risks

• Future capital needs are uncertain, and additional capital may not be available on attractive terms, if at all, potentially limiting business growth and ability to continue as a going concern.
• Continued significant losses and potential future losses, which could adversely affect the business and stock price if consistent progress toward profitability is not made.
• Operating results are substantially dependent on developing new products and achieving 'design wins,' making future revenues highly dependent on winning slots for new product offerings.
• Heavy dependence on a single electronics distribution company (RFPD) to augment sales reach and stock products, posing risks of significant sales loss or default in accounts receivable if the relationship is disrupted.
• Heavy dependence on third-party suppliers for complex manufacturing processes (die processing, packaging, test, tape and reel), leading to supply chain disruption risks, quality issues, and potential inability to satisfy customer orders.
• Sales to several large companies with considerable bargaining power may require agreement to unfavorable terms and conditions, affecting revenue recognition, increasing costs, or harming the business.
• Risks related to sales through independent sales representatives and distributors, including competitive pressure, concentration, credit risk, and compliance risks (e.g., FCPA violations).
• Business disruptions from natural disasters, industrial accidents, cybersecurity incidents, telecommunications failures, power/water shortages, extreme weather, public health issues, military actions, acts of terrorism, or political/regulatory issues.
• Poor manufacturing yields can significantly impact operating results, increasing costs, lowering cash flows, and damaging market position and reputation.
• Inventory risks and costs due to building products based on anticipated customer orders and forecasts, which may not materialize or may be lower than expected.
• Operating in a very competitive industry requiring continuous innovation to keep pace with rapid technological change and competitor advancements.
• Unfavorable changes in interest rates, pricing of certain precious metals, utility rates, and foreign currency exchange rates may adversely affect financial condition, liquidity, and results of operations.
• Failure to attract, retain, and motivate key employees, especially in RF engineering, software engineering, integrated circuit design, and technical marketing and support, could harm the business.
• Litigation or legal proceedings could expose the company to significant liabilities, occupy management's time, and damage its reputation.
• Warranty claims, product recalls, and product liability claims could lead to significant expenses and materially and adversely affect financial condition and results of operations.
• Reliance on intellectual property (patents, trademarks, trade secrets) and the risk of not being able to successfully protect against third-party use or being subject to claims of infringement.
• Risks from manufacturing and packaging products by outside parties located in Taiwan, Singapore, the Philippines, and Malaysia, including quality failures, export/import complexities, geopolitical issues, and factory disruptions.
• Government regulation may adversely affect the business, including U.S. Department of Commerce import/export controls (e.g., Entity List), FCPA, environmental laws, and foreign government tariffs/restrictions.
• Economic regulation in the People's Republic of China (PRC) and other countries, including trade policies, tariffs, and export restrictions (e.g., U.S. restrictions on advanced computing chips to PRC), could adversely impact sales and operations.
• Security breaches and other disruptions could compromise proprietary information and expose the company to liability, damaging its business and reputation.
• Theft, loss, or misuse of personal data by or about employees, customers, or third parties, which could increase expenses, damage reputation, or result in legal/regulatory proceedings (e.g., GDPR penalties).
• A limited market for common stock on OTCQX, leading to significant volatility and difficulty in selling shares.
• No intention to pay dividends for the foreseeable future, meaning returns depend solely on stock price appreciation.
• Future sales and issuances of securities could result in additional dilution of percentage ownership for existing shareholders.
• Anti-takeover provisions in charter documents and Delaware law could make an acquisition more difficult.
• Lack of research analyst coverage from major brokerage firms due to not being a traditional underwritten IPO.
• Status as an emerging growth company and smaller reporting company, with reduced reporting and disclosure requirements, could make common stock less attractive to investors.
• Potential for securities litigation resulting in significant legal expenses and settlement or damage awards.
• FINRA sales practice requirements may limit a stockholder's ability to buy and sell the stock if it is deemed a 'penny stock'.

Future Outlook

The company expects to continue experiencing net losses and negative cash flows in the near term as it grows. Management believes that existing cash resources, available borrowings, and amended debt terms provide sufficient liquidity to fund operations for at least the next twelve months. The company anticipates continued investment in research and development, sales and marketing, and administrative infrastructure, while remaining focused on driving further operating efficiencies and improving cash flow to support its long-term strategic plan. R&D, sales and marketing, and general and administrative expenses are expected to increase in absolute dollars but decrease as a percentage of revenues over the longer term.

Management Comments

• "Management believes that the Company's existing cash resources, together with available borrowings and amended debt terms, provide sufficient liquidity to fund operations for at least the next twelve months."
• "Management views these amendments [to Salem Loan Facility] as constructive developments, reflecting the Company's improved operating performance, disciplined execution of strategic initiatives, and proactive balance sheet management."
• "Management remains focused on driving further operating efficiencies and further improving cash flow."
• "Management believes these ongoing efforts, combined with existing liquidity resources, will support the Company's ability to continue executing its long-term strategic plan."

• "Management concluded past material weaknesses have been successfully remediated and that our internal control over financial reporting was effective as of December 31, 2025."

Industry Context

StockSavvy.ai notes that Guerrilla RF's growth in automotive and catalog markets aligns with broader industry trends of increasing demand for RF semiconductors in modern vehicles (V2X, GPS, 5G) and diversified applications (IoT, SatCom). The decline in wireless infrastructure revenue, however, contrasts with the general multi-year technology upgrade cycles to 5G, suggesting potential competitive pressures or specific customer cycle impacts within that segment. The company's fabless model and global supply chain expose it to the cyclical nature and geopolitical risks inherent in the semiconductor industry, particularly with manufacturing partners in Asia.

Comparison to Industry Standards

• The semiconductor industry is highly competitive, with competitors like Qorvo, Inc., NXP Semiconductors N.V., Skyworks Solutions, Inc., and MACOM Technology Solutions Inc. having entrenched market positions, established patents, and substantial technological/financial resources.
• Guerrilla RF's gross margin of 65.3% in 2025 is strong, indicating effective pricing and product mix, potentially competitive with or exceeding some industry averages for specialized MMIC products.
• The company's R&D investment, while decreasing in absolute terms in 2025, is crucial for innovation in a rapidly changing industry, where competitors often have larger R&D budgets.
• Customer concentration (RFPD at 65% of revenue) is higher than ideal for industry diversification standards, posing a significant risk compared to more diversified competitors.
• The company's attrition rate is consistently below the technology industry average, indicating strong employee retention, which is a positive for a talent-intensive industry.

Legal Proceedings

• Not a party to any material pending legal proceedings as of December 31, 2025. May become involved in lawsuits and legal proceedings that arise in the ordinary course of business from time to time.

Related Party Transactions

• In July 2023, the Chief Executive Officer and his family members purchased Convertible Notes totaling $710,000, which were subsequently converted into equity on March 28, 2024.
• AMB Investments, LLC, whose president serves as a Company director, acquired a 47.17% participation interest in $5.5 million of additional advances under the Salem Loan Facility in the second half of 2023, giving it a pecuniary interest in approximately $2.6 million of the loan facility and 500,000 shares of common stock.
• Certain existing shareholders, including investors affiliated with certain directors and officers, purchased an aggregate of 612,473 Units in the initial closing of the 2024 Private Placement on March 28, 2024.

Stakeholder Impact

• Shareholders face potential for dilution from future equity raises, volatility in stock price, and no expected dividends. The concentrated control by North Run may limit other stockholders' influence. However, improved financial performance (reduced losses, positive operating cash flow) could positively impact shareholder value.
• Employees benefit from competitive pay and benefits, stock-based compensation, retirement programs, unlimited personal time off, and health and wellness benefits. Investment in development programs and a low attrition rate indicate a positive work environment. The hiring of a new CFO strengthens financial leadership.
• Customers can expect continued focus on high-performance MMIC products, an expanded product catalog, high-quality customer support, and strong relationships with distributors. Risks include potential supply chain disruptions and product defects.
• Suppliers benefit from long-term strategic relationships with manufacturing partners, diversification of sourcing strategies, and contingency plans to mitigate supply chain risks.
• Creditors are positively impacted by the company's improved operating performance and proactive balance sheet management, such as the Salem Loan Facility amendment, which enhances the company's ability to meet debt obligations.

Next Steps

• Continue investment in research and development, sales and marketing, and administrative infrastructure.
• Drive further operating efficiencies and improve cash flow.
• Monitor global supply chain dynamics and proactively work with manufacturing partners to ensure stability.
• Regularly evaluate and expand supplier base, redesign products, qualify multiple wafer foundries, and extend/add supply commitments to increase supply chain flexibility.
• Continue to attract, develop, retain, and motivate employees.
• Continue to add personnel and resources in sales and marketing to expand brand awareness and capitalize on sales opportunities.
• Improve sales execution to increase sales opportunities and grow revenues.
• Assess the potential impact of recently issued accounting pronouncements (ASU No. 2023-09, ASU No. 2024-03, ASU 2025-05) on financial statements and disclosures.

Key Dates

Recommendation

While Guerrilla RF demonstrated significant improvements in revenue growth, gross margin, and operating loss, achieving positive operating cash flow in the latter half of 2025, the company continues to report substantial net losses and an accumulated deficit. The high customer concentration and the inherent cyclicality and competitiveness of the semiconductor industry, coupled with geopolitical risks in its supply chain, present ongoing challenges. The recent capital raises and debt restructuring provide near-term liquidity, but the need for future capital remains a concern. The stock is currently quoted on OTCQX, which implies lower liquidity and higher volatility. Given the mixed financial signals—strong operational improvements against persistent losses and significant risks—a "hold" recommendation is appropriate for a seasoned investor, suggesting monitoring progress towards sustained profitability and risk mitigation before a more aggressive stance.
