Biopharma delivers blockbuster growth
Despite a sell-off in biotech stocks in recent years, the sector’s medical advances are translating into record drug sales and creating opportunities for investors, says Portfolio Manager Andy Acker.

- In 2022, large “blockbuster” biotech drugs delivered a total of $464 billion in sales, up 12% from the year prior and 70 times what they were roughly two decades ago.
- With innovation continuing, particularly in large disease categories such as Alzheimer’s, obesity, and cancer, revenues could continue to expand in the coming years.
- In our view, valuations for the biotech companies driving much of today’s innovation have yet to reflect this growth potential, creating opportunities for investors.
If you were to look at the performance of biotech stocks over the past two years, you might reason the sector’s growth potential had stalled, if not stopped altogether. Since peaking in February 2021, a broad index that includes small- and mid-cap biotechs – the sector’s main innovation engine – is down nearly 60%. (By comparison, the S&P 500 Index was up 8.5% over the same period.)1
But look past the broad market performance and the story changes dramatically. Last year, revenues for blockbuster drugs (medicines with annual revenues of $1 billion or more) topped $460 billion, up 12% from the prior year. Just five years ago, blockbuster revenues were only half as much. In addition, the number of blockbuster drugs has grown rapidly. In 2022, there were nearly 120 blockbusters. In 2000, that number was just two.2
The biotech sell-off can be attributed to many reasons, including valuations that got overstretched during COVID-19 and regulatory uncertainty during a change of leadership at the Food and Drug Administration (FDA). More recently, rising interest rates have been a headwind. But all the while, the sector’s innovation has been gaining momentum – and may soon be too hard to dismiss. This year, more than 75 new medicines are pending approval decisions by the FDA, which could result in a record number of new drug launches for the year. (Currently, the record stands at 59 in 2018.3) What’s more, many of the therapies under review could represent medical breakthroughs that could alter the standard of care – and mark the start of 10-year product cycles.
Consider NASH, a nonalcoholic form of fatty liver disease. Although more than 10 million people in the U.S. suffer from NASH, no approved treatments exist for the condition, which is quickly becoming a leading cause of liver failure. That could change in the near future: one medicine is set to be reviewed by the FDA in the coming months, and two others have delivered impressive clinical trial data, including the ability to improve fibrosis (tissue scarring) and resolve NASH in a meaningful percentage of patients.
Drug revenues rise

These types of medical advances are becoming widespread, from rare diseases affecting a few thousand patients to conditions impacting millions of people. COVID-19 product sales, for example, topped $90 billion in 2022 for a disease that didn’t even exist three years ago.4 While these revenues are expected to decline in 2023, other large end markets – obesity, diabetes, hemophilia, cancer, and Alzheimer’s disease, to name a few – could see large revenue growth. In a late-stage clinical trial last year for obesity, for example, one therapy delivered weight loss of over 20%, a level previously possible only through bariatric surgery. And in January, the FDA approved Leqembi for Alzheimer’s, the first treatment to clearly slow the rate of cognitive decline in the early stages of the disease.
Plugging revenue holes is increasingly becoming a necessity for large-cap pharmaceutical companies. Over the next five years, more than $160 billion in drug sales are expected to be lost to patent expirations and competition from generics and biosimilars.5 At the same time, the Inflation Reduction Act, passed in 2022, will allow the U.S. federal government to negotiate pricing for select drugs, starting in 2026. While the impact of these and other provisions remain uncertain, some drugmakers have already warned about negative impacts to certain research initiatives and/or sales.
We are optimistic that the industry will be able manage both loss of exclusivity and regulatory changes (global prescription drug sales are projected to reach $1.6 trillion by 2028, up 40% from 20226). But for many large pharmaceutical companies, maintaining growth will require increased business development activity, including mergers and acquisitions. The upcoming challenges underscore the need to identify the companies most at risk – and those that could stand to benefit. As we have noted over the past year, large-cap pharmaceutical companies have an estimated $500 billion in available cash to replenish product pipelines.7 We believe biotech’s combination of low valuations and accelerating innovation create the potential for upside: of deals announced within recent months, many have offered premiums of 100% or more. Should innovative new medicines continue to be developed for high, unmet medical needs, we believe more blockbuster deals will ensue.
Health care industries are subject to government regulation and reimbursement rates, as well as government approval of products and services, which could have a significant effect on price and availability, and can be significantly affected by rapid obsolescence and patent expirations.

Please read the following important information regarding funds related to this article.
- Shares/Units can lose value rapidly, and typically involve higher risks than bonds or money market instruments. The value of your investment may fall as a result.
- Shares of small and mid-size companies can be more volatile than shares of larger companies, and at times it may be difficult to value or to sell shares at desired times and prices, increasing the risk of losses.
- If a Fund has a high exposure to a particular country or geographical region it carries a higher level of risk than a Fund which is more broadly diversified.
- The Fund is focused towards particular industries or investment themes and may be heavily impacted by factors such as changes in government regulation, increased price competition, technological advancements and other adverse events.
- The Fund may use derivatives to help achieve its investment objective. This can result in leverage (higher levels of debt), which can magnify an investment outcome. Gains or losses to the Fund may therefore be greater than the cost of the derivative. Derivatives also introduce other risks, in particular, that a derivative counterparty may not meet its contractual obligations.
- If the Fund holds assets in currencies other than the base currency of the Fund, or you invest in a share/unit class of a different currency to the Fund (unless hedged, i.e. mitigated by taking an offsetting position in a related security), the value of your investment may be impacted by changes in exchange rates.
- When the Fund, or a share/unit class, seeks to mitigate exchange rate movements of a currency relative to the base currency (hedge), the hedging strategy itself may positively or negatively impact the value of the Fund due to differences in short-term interest rates between the currencies.
- Securities within the Fund could become hard to value or to sell at a desired time and price, especially in extreme market conditions when asset prices may be falling, increasing the risk of investment losses.
- The Fund may incur a higher level of transaction costs as a result of investing in less actively traded or less developed markets compared to a fund that invests in more active/developed markets. These transaction costs are in addition to the Fund's Ongoing Charges.
- The Fund could lose money if a counterparty with which the Fund trades becomes unwilling or unable to meet its obligations, or as a result of failure or delay in operational processes or the failure of a third party provider.
