Moderna stock took a significant hit on Monday, plunging by 20% after the company lowered its sales forecast for 2025 by approximately $1 billion. The biotech company cited several potential headwinds later in the year that could affect its revenue growth. This downgrade comes at a time when Moderna continues to focus on cost-cutting measures and expanding its portfolio beyond its Covid-19 vaccine.
In this article, we will take a closer look at why Moderna revised its 2025 revenue outlook, the factors contributing to the lowered guidance, and what this means for the future of Moderna stock and its pipeline of mRNA-based therapies.
Moderna Stock Faces Significant Setback
Moderna’s new 2025 revenue projection now ranges from $1.5 billion to $2.5 billion, with most of the expected income coming in the latter half of the year. This marks a sharp decline from the company’s previous forecast of $2.5 billion to $3.5 billion, a guidance issued just a few months ago in September 2024. At that time, Moderna had set ambitious goals, including breaking even on an operating cash basis by 2028, up from its previous goal of 2026. The company had also projected $6 billion in revenue.
The revised forecast and the subsequent drop in Moderna stock reflect the biotech giant’s ongoing challenges, especially as it navigates the post-Covid vaccine market and works to diversify its offerings. The company’s stock was not alone in taking a hit: other vaccine stocks also saw declines, with Novavax dropping 6% and BioNTech falling 4% in early trading on Monday.
The Impact of Increased Competition in the Covid Market
One of the primary reasons for the downward revision in sales expectations is the increasing competition in the Covid-19 vaccine market. Moderna’s CFO, Jamey Mock, highlighted that the company’s market share in the U.S. retail Covid vaccine market had already dropped to 40% by the end of 2024, down from 48% in 2023. The company is bracing for further declines in its market share, as more competitors vie for a piece of the vaccine pie.
A significant factor contributing to this intensified competition is Sanofi’s partnership with Novavax. Under a new agreement, Sanofi will co-commercialize Novavax’s Covid vaccine globally. This strategic collaboration could make Novavax’s offering more competitive, particularly as governments around the world plan for future vaccine procurement.
Falling Vaccination Rates and Other Headwinds
Another concern that Moderna faces is the ongoing decline in vaccination rates. Mock pointed out that U.S. vaccination rates in the retail market fell by approximately 7% in fall 2024 compared to the same period in 2023. This drop could be indicative of the broader trend of waning interest in Covid-19 vaccinations, making it more challenging for Moderna to maintain its previous levels of revenue.
Additionally, Moderna is facing uncertainty around manufacturing contracts with several countries, which could affect the company’s ability to meet demand in key international markets. Another significant factor is the uncertainty surrounding recommendations for RSV (respiratory syncytial virus) vaccination. Moderna’s newly launched RSV vaccine has garnered attention, but the company is uncertain about what the Centers for Disease Control and Prevention (CDC) advisory committee will recommend regarding its use and potential revaccination protocols.

Cost-Cutting Measures to Preserve Cash
Despite the downward revision in sales expectations, Moderna remains committed to its cost-cutting initiatives. The company plans to reduce its cash cost expenses by $1 billion in 2025 and aims for an additional $500 million in cost reductions by 2026. These moves are part of the company’s broader strategy to preserve cash as it diversifies its product pipeline and explores new opportunities beyond Covid-19 vaccines.
“We are taking the right amount of cost to preserve our cash,” said Mock. “We’re excited to invest and increase our portfolio.” Moderna’s focus on diversifying its offerings is important as it seeks to reduce its reliance on Covid vaccine sales, which have experienced a significant decline from their peak in 2021 and 2022.
Moderna’s Path Forward: Diversification and Future Approvals
Looking ahead, Moderna is betting on its messenger RNA (mRNA) technology, which has proven successful with both its Covid-19 and RSV vaccines. The company plans to expand its portfolio with at least 10 new product approvals over the next three years. Among the most anticipated products are a combination vaccine targeting both Covid-19 and the flu, as well as a next-generation Covid-19 vaccine.
In fact, Moderna expects to receive three product approvals in 2025 alone. These new offerings could help Moderna navigate the post-Covid landscape and diversify its revenue streams. The company has also made it clear that it is committed to using its mRNA platform for innovative treatments in other areas, including cancer, cardiovascular diseases, and autoimmune disorders.
While the decline in Covid vaccine sales has undoubtedly affected Moderna’s financial outlook, the company is making strides in positioning itself for long-term growth. Its mRNA platform holds significant promise for the development of new vaccines and therapies across various therapeutic areas. As Moderna continues to expand its pipeline and reduce costs, it remains a key player in the biotech and pharmaceutical sectors.
What This Means for Moderna Stock
The 20% drop in Moderna stock after the company lowered its sales forecast is a clear signal that investors are concerned about the company’s near-term prospects. The challenges faced by Moderna in the Covid vaccine market are real, and it will take time for the company to adjust to the changing dynamics of global vaccine demand. However, Moderna’s commitment to diversifying its portfolio with mRNA-based therapies offers a glimpse of hope for investors looking for growth opportunities in the future.
While the immediate outlook for Moderna stock may be uncertain, the company’s investments in new vaccine candidates and its focus on cost reduction could provide a strong foundation for long-term success. For now, Moderna will need to navigate the challenges of the current vaccine market while also preparing for the next wave of innovation.
Conclusion
Moderna stock’s 20% drop is a clear indication that the company is facing some headwinds as it looks to adjust to the changing dynamics of the vaccine market. With increased competition, falling vaccination rates, and ongoing uncertainties, Moderna is taking steps to preserve cash and invest in the future. The company’s focus on expanding its portfolio beyond Covid vaccines and diversifying its product pipeline could help drive growth in the years to come.
For investors, this is a crucial time to watch how Moderna navigates these challenges and how its mRNA platform evolves to address other global health issues. While the near-term outlook may be turbulent, Moderna’s long-term potential remains significant, making it a stock worth watching closely.
