 Year in Review 2025

December 19, 2025

 

Holiday greetings from the team at RiverVest.

 

In September, RiverVest marked the 25th anniversary of its first closing of RiverVest Venture Fund I. Over this quarter-century, the firm has navigated a wide range of economic cycles and market conditions. While our team has grown and opportunities have shifted, our fundamental strategy and philosophy have been constant: as a firm, we strive always to find novel approaches to address significant unmet medical needs that offer potential for meaningful progress and, ultimately, a strong return on investment. Scientific rigor continues to be the foundation on which we assess opportunities. This disciplined approach has led to 23 successful exits over the years — most recently, the pending acquisition of Bluejay Therapeutics, described below. Our work has also led to 32 products reaching the market from companies in which RiverVest was an investor.

Looking Back at 2025

Each year is unique in some respects, and certainly, 2025 has been an unusual one for the life sciences industry. Accordingly, our focus this year was on our current portfolio companies. Amid a period of broader uncertainty, we wanted to do all that we could to position them optimally for the future. To that end, we made investments in nine existing portfolio companies (shown below) during 2025, and we are thoughtfully reserving dry powder to support future financings. We are quite bullish on these companies and prioritized backing them with the resources they need to make progress during a time when many venture-backed companies have struggled to raise new financing rounds. We end 2025 confident that our portfolios are well positioned for a variety of scenarios in 2026 and excited about their prospects.

A few factors have been especially significant in contributing to uncertainty this year. First, the prospect of tariffs has loomed large in the pharmaceutical industry, as there is a heavy reliance on ex-U.S. production. Due primarily to differing tax policies, roughly 40% of finished drugs and 80% of active ingredients in drugs that are administered in the U.S. are sourced from abroad. Second, there has been a fairly steady drumbeat of pressure on drug companies to price their products similarly between the U.S. and other countries. This is important, as prices here have typically been far higher than in many other parts of the world (estimated on average to be almost 3x higher). The disparity in pricing is troubling, but a quick solution is difficult to achieve without disruption to the industry. Third, the regulatory infrastructure in the U.S. (notably the Food and Drug Administration) has undergone considerable change, leading to concerns over regulatory timelines and potential changes in approval criteria.

 

These factors produced various ripple effects. Drug companies faced increasing uncertainty about their future profitability, as revenues could be lower, and expenses could be higher. For a time, primarily in the first half of the year, their valuations suffered, prompting greater caution and fewer acquisitions. Consequently, the industry continued a trend that began several years ago in which acquisitions of smaller biopharma companies were relatively infrequent, and initial public offerings were extremely rare. Many startup companies, needing to stay independent longer than anticipated, were forced to raise more equity than originally planned. This, in turn, often created downward pressure on valuations, even when the companies were performing well, as companies raised later equity rounds.

 

While questions remain regarding tariffs, drug pricing policy, and the ongoing transition at the FDA, the industry appears to be shrugging off these concerns to a fair extent. There are indications that envisioned policy changes may be less significant than initially communicated. Also, the industry is adapting, announcing intentions to bring some production back to the U.S. and negotiating pricing arrangements with the federal government that are more favorable to the industry than had been feared. The situation at the FDA varies by therapeutic area, but the agency is taking steps to accelerate approvals for certain drugs and devices, signaling a willingness to grant approvals with less data than has historically been required. Consequently, valuations have ticked up, most notably in the publicly traded biotech indices, which are now up roughly 30% year-to-date. Valuations of private companies have not yet caught up, but we are seeing successful new financing rounds as well as solid, if not spectacular, M&A activity.

One recent example of M&A activity is the definitive agreement announced last week that Bluejay Therapeutics — a RiverVest Venture Fund V portfolio company — will be acquired by Mirum Pharmaceuticals, a former Fund IV portfolio company. This deal, expected to close in the first quarter of 2026, will provide an attractive return to our investors while helping to advance an antibody showing great promise as a potential therapy for chronic hepatitis D and chronic hepatitis B.

Looking to the Future

Looking to 2026, we are hopeful that the recent momentum will continue. Even with uncertainties that can impact the short term, in the long run, there will continue to be very positive forces that underpin our confidence in the life sciences sector. People will want to live longer, fuller lives. Scientists will work to better understand and tackle diseases, especially those for which current therapies are most inadequate. Drug and device makers will value innovations that can lead to novel therapies, and they will want to shore up their pipelines to replace products that go off patent.


With that as a backdrop, we hope to see additional lucrative exits in the coming year, as several of our portfolio companies are on track to report data from major clinical studies in 2026. With compelling data, these companies could be attractive acquisition candidates.


We are proud of RiverVest’s successful 25-year history and excited for the next 25 years, driven by our founding values, our disciplined approach, and an unwavering commitment to improving the lives of patients, supporting entrepreneurs, and earning the trust of our investors. Thank you for being part of this journey. We wish you happy holidays and a healthy and prosperous new year.


Sincerely,

The RiverVest Team
