GlaxoSmithKline (LSE:GSK), is undergoing a transformation and the company is expected to split into 2 entities mid 2022. Shareholders had an underwhelming performance in the last 3 years, and the uncertainty of the outcome of the spinoff may be keeping the stock down. We will overview the current and future financial performance of the company and use a proxy to determine the disposition for the future of the company.

GlaxoSmithKline operates in three segments and had the following 2020 revenues per segment:

  • Pharmaceuticals: UK£17b
  • Vaccines: UK£6.9b
  • Consumer Healthcare: UK£10b

The separation will split the consumer healthcare segment from the other two. Essentially creating one entity with revenue capacity of UK£24b, which is expected to grow to UK£33b as the New GSK, and the Consumer Healthcare company with a UK£10b revenue starting point. New GSK is set to be R&D heavy, while the Consumer Healthcare company will maintain a product portfolio and optimize efficacy of operations.

For investors this creates a rather complicated situation in estimating the future performance of either company, that is why we will look at the proxy of insider transactions, with the assumption that insiders might be well-informed and trading based on their experience with the company.

Although we don't think shareholders should simply follow insider transactions, logic dictates you should pay some attention to whether insiders are buying or selling shares.

GlaxoSmithKline Insider Transactions Over The Last Year

The Senior Independent Non-Executive Director Manvinder Banga made the biggest insider purchase in the last 12 months. That single transaction was for UK£503k worth of shares at a price of UK£13.76 each. That means that an insider was happy to buy shares at around the current price of UK£13.88.

We do always like to see insider buying, but it is worth noting if those purchases were made at well below today's share price, as the discount to value may have narrowed with the rising price.

The good news for GlaxoSmithKline share holders is that insiders were buying at near the current price.

Over the last year, we can see that insiders have bought 61.76k shares worth UK£840k. But they sold 39.99k shares for UK£509k.

In total, GlaxoSmithKline insiders bought more than they sold over the last year.

It's good to see that GlaxoSmithKline insiders have made notable investments in the company's shares. In the last 3 months, four insiders shelled out UK£70k for shares in the company -- and none sold. This is a positive in our book as it implies some confidence.

When we dig a bit deeper, we can see that besides the separation of the company, GSK has a rich pipeline of potential vaccines that are in various stages of clinical development. The estimated success of these vaccines could be pertly the reason why insiders are still buying the stock.
