Financial Performance and Operational Resilience

Harvard Bioscience's recent financial performance reflects a company in transition, balancing macroeconomic headwinds with strategic operational improvements. For the three months ended September 30, 2025, revenues decreased by $1.40 million, or 6.30%, to $20.591 million, compared to $21.970 million in the prior year period. This decline was primarily attributed to softening worldwide demand from academic research institutions and CROs, alongside the impact of reciprocal tariffs. For the nine months ended September 30, 2025, total revenues were $62.815 million, a 9.70% decrease from $69.579 million in the same period of 2024.

Despite the revenue contraction, the company demonstrated notable operational discipline. Gross profit for Q3 2025 decreased by $0.80 million, or 5.80%, to $12.021 million. However, the gross margin improved to 58.40% from 58.10% in Q3 2024, primarily due to a favorable product mix and disciplined execution. This margin expansion, even with lower revenue, highlights the effectiveness of cost-cutting measures. Adjusted EBITDA for Q3 2025 increased sequentially to $2 million, up from $1.3 million in Q3 2024. This improvement was largely driven by a $1.4 million reduction in operating expenses, resulting from initiatives such as the consolidation to one U.S. ERP system, streamlining the SG&A organization, and reprioritizing New Product Introduction (NPI) projects.

Operating expenses across sales and marketing, general and administrative, and research and development all saw reductions for both the three and nine months ended September 30, 2025, primarily due to decreased compensation, travel, entertainment, and trade show expenses. These efforts underscore management's commitment to financial discipline, a key priority outlined by CEO John Duke.

A significant non-cash event impacting profitability was the $48 million goodwill impairment charge recorded in Q1 2025. This was triggered by a sustained decrease in the company's stock price, recent operating results, liquidity risk, and broader macroeconomic conditions affecting the life sciences industry. While non-cash, it reflects a re-evaluation of the company's valuation in a challenging market.

From a liquidity perspective, Harvard Bioscience faces a critical juncture. As of September 30, 2025, the company had $34 million in outstanding indebtedness under its term loan and senior revolving credit facility. The company received an amendment to its Credit Agreement on August 8, 2025, waiving prior events of default related to refinancing milestones and financial covenants. However, HBIO is required to complete steps towards refinancing or repaying this debt by December 5, 2025. The 10-Q explicitly states "substantial doubt about the Company's ability to continue as a going concern" unless it can secure alternative capital or extend the repayment date. This highlights the urgency of the ongoing refinancing efforts.

Despite these challenges, cash flow from operations has shown improvement. For the nine months ended September 30, 2025, net cash provided by operating activities was $6.825 million, a significant increase from $0.285 million in the prior year period. This positive trend was supported by a $2.80 million reduction in accounts receivable, a $1.60 million reduction in inventories, and $2.20 million in Employee Retention Tax Credit (ERTC) refunds. Net debt also decreased by over $6 million from year-end 2024 to $27.5 million, reflecting quarterly principal payments and improved operating cash flow. These operational improvements are crucial as the company seeks to secure a new, more flexible debt facility.

Outlook and Strategic Momentum

Looking ahead, Harvard Bioscience anticipates continued momentum into the fourth quarter of 2025. The company has provided revenue guidance of $22.5 million to $24.5 million, which at the high end, could result in flat revenue year-over-year for the quarter. Gross margin is projected to be between 58% and 60% for Q4 2025, reflecting expected improvements from higher volumes. This positive outlook is underpinned by mid-single-digit year-over-year order growth in Q3 2025 and four consecutive months of year-on-year growth, leading to the strongest backlog since Q1 2023.

A key assumption in this guidance is the potential impact of a prolonged U.S. government shutdown on NIH funding, which could affect the lower end of the revenue range. However, management expects that any delayed funds would likely flow into the first or second quarter of 2026. Optimism also surrounds the subsiding of tariff disruptions in China, with expectations for increased activity moving forward.

The company's strategic initiatives, under CEO John Duke, are focused on maintaining financial discipline, accelerating product adoption, and strengthening the capital structure. The expansion of the distribution agreement with Fisher Scientific across North America is a significant move to broaden market access and enhance visibility for HBIO's product portfolio, particularly its cellular and molecular technology products. This partnership is expected to leverage Fisher Scientific's extensive commercial reach within academic and pharmaceutical research markets.

The ongoing debt refinancing process remains a critical priority, with management actively reviewing multiple proposals and expecting a resolution within Q4 2025. While the new debt is anticipated to be at a higher interest rate than commercial debt, the goal is to secure a multi-year term that provides the flexibility needed to invest in growth initiatives, such as expanding capacity for new products.

Risks and Challenges

Despite the operational improvements and strategic initiatives, Harvard Bioscience faces several significant risks that warrant close investor attention. The most pressing is the "substantial doubt about the Company's ability to continue as a going concern" unless it can successfully refinance its $34 million debt by December 5, 2025, or secure alternative capital. There is no assurance that such capital will be available on commercially acceptable terms or provide sufficient funds. Failure to meet this deadline could result in the outstanding debt becoming immediately due and payable, jeopardizing current operations.

Another material risk is the company's non-compliance with Nasdaq's minimum bid price requirement. While an extension has been granted until March 30, 2026, failure to regain compliance could lead to delisting, negatively impacting the company's ability to raise capital, and affecting the market price and liquidity of its common stock.

Macroeconomic factors continue to pose challenges. Uncertainty surrounding NIH funding and the potential for a prolonged U.S. government shutdown could delay academic purchasing cycles, impacting revenue. While there is optimism regarding China tariffs, volatility in European tariffs remains an "open area," potentially affecting costs and revenue. The $48 million goodwill impairment charge in Q1 2025 highlights the sensitivity of the company's valuation to market capitalization and operating performance, with further impairment charges possible if conditions deteriorate.
