The quarter included US Food and Drug Administration (FDA) approvals of the firm’s severe ulcerative colitis treatment, Omvoh, and an expanded indication for Jardiance in chronic kidney disease. Eli Lilly also released positive results for its mirikizumab Phase 3 VIVID-1 study, which evaluated the drug’s safety and efficacy in treating Crohn’s disease.

The firm’s revenue was up 37 percent year-on-year, partially due to Eli Lilly’s type 2 diabetes injection Mounjaro, which is expected to be a mega-blockbuster drug and could also treat chronic obesity.

FAQs for pharmaceutical stocks

What does the pharmaceutical industry do?

The pharmaceutical industry encompasses a variety of companies that have different — although sometimes overlapping — roles to play. The most famous players are the big pharma companies. These giants often have a variety of subsidiaries, large pipelines and many products in their portfolios. There are also smaller pharma R&D companies, which sometimes get acquired by larger firms if their work seems promising. Companies in these categories research, develop and sometimes bring to market drugs aimed at filling unmet needs, such as products to treat conditions that are currently untreatable or to help people who are resistant to pre-existing treatment options.

Once patents run out on prescription drugs, generic drug manufacturers create much cheaper generic versions. Wholesale companies also play a large role in the pharma sector. According to Common Wealth Fund, wholesalers have four areas through which they affect the buying and distribution of drugs: ‘setting generic drug prices, leveraging list price increases, competing in specialty drug distribution, and mitigating or exacerbating drug shortages.’

What is the big pharma business model?

Big pharma companies have a fairly consistent business model. Often, the company’s R&D team will slowly develop a new drug through many stages of testing to prove the drug’s efficacy, safety and necessity.

If all trials are completed successfully, the company will apply to government organizations such as the FDA, which must approve the drug before it can be mass produced, marketed and sold. Companies can skip a number of these steps by acquiring smaller companies, or through in-licensing, which results in two companies sharing the burden of a drug’s development through to commercialization. However, it’s worth noting that large pharma companies have many drugs in their pipelines at any given time, and many don’t make it to approval.

Once a drug is approved by the relevant health organization, it can then be marketed and prescribed. Because patents expire after 20 years, companies lobby and advertise to try to get as many sales as possible during that window.

Who are the ‘Big 3’ in pharma?

The ‘Big 3’ in pharma refers to the three largest wholesalers: AmerisourceBergen (NYSE:ABC), Cardinal Health (NYSE:CAH) and McKesson (NYSE:MCK). Collectively, those three companies account for over 92 percent of wholesale prescription drug distribution in the US.

Which country is number one in the pharma industry?

The US is the top pharmaceutical country, with five of the top 10 pharma companies by revenue headquartered in the nation, including the top three of Pfizer (NYSE:PFE), AbbVie and Johnson & Johnson. The country is also in the lead when it comes to consumer spending on pharmaceuticals due to the high cost of brand-name drugs.

The US is also the top country globally for R&D spending — companies that are part of PhRMA, a trade group that represents US biopharmaceutical companies, spent US$100.84 billion on R&D in 2022 out of a total of US$244 billion spent by pharmaceutical companies globally that year.

What are the problems in the pharmaceutical industry?

One of the largest problems with the pharmaceutical industry, particularly in the US, is the high cost of treatments. According to a study looking at American prescription drug spending between 2016 and 2021, prescription drug prices were 2.5 times the cost on average of prices in similar high-income nations.

An example that has been at the center of discourse in recent years is insulin, which can cost Americans with type 1 diabetes over US$1,000 per month. In early 2023, US President Joe Biden signed the Inflation Reduction Act into law, and it includes a cap of US$35 per month on insulin for seniors on Medicare, although it does not help people who are uninsured or have private health insurance. Eli Lilly has now instituted that same price cap for all users of their insulin, and there is push for further legislation.

However, while progress in insulin pricing is happening, it’s far from the only medication with high costs. According to the aforementioned study, the top 10 percent most expensive drugs account for less than 1 percent of all prescriptions, but make up 15 percent of all retail prescription spending.

While generic versions of medications are relatively cheap, they can’t be created until patent protection for the brand name version expires, which is usually 20 years after filing for the patent.

What is the future of pharmaceuticals?

Pharmaceutical companies will have to adapt to changing times moving forward. The world is shifting, with economic woes, geopolitical disruptions and supply chain concerns affecting nearly every sector. Innovation continues to accelerate as well, and the medical landscape has changed in the wake of COVID-19. Additionally, the US government is making moves to address the astronomical prices of prescription medicine as the industry comes under increasing scrutiny.

Are pharmaceutical stocks risky?

While established players like the big pharma and wholesale companies discussed above should be relatively consistent, small companies are make-or-break depending on whether their drugs are successful. This means that investors could see much higher returns compared to large companies, but run the risk of taking massive losses in the case of failure.
