CSL Ltd (ASX: CSL) shares have had a tough ride over the past couple of years.
The shares were relatively stable, mostly trading between $250 and $300 between late-2019 until around August last year.
Then they crashed.
Between mid-August to late-May this year, CSL shares shed around 64% of their value. On the 3rd of June, the shares closed at an 11-year low of just $92.24 a piece.
The good news is that since hitting that low, the shares have rebounded around 113% at the time of writing, to $196.91.
It’s an incredible reversal for the ASX biotech stock.
Some are now incredibly bullish that the company can keep climbing higher, but some more reserved market experts think there is potential for another tumble ahead.
I decided to look at both the bull and the bear case for CSL shares, and came up with my own conclusion.
Here’s what I found.
The bull case for CSL shares
CSL has an incredibly dominant market position in a high-growth market. The global biotechnology company develops and delivers biotherapies and vaccines to support people with life-threatening medical conditions.
Its plasma therapies business (CSL Behring) is a major powerhouse in the global plasma market. Alongside competitors Grifols and Takeda, the three businesses control around 80% of the global plasma therapy market.
Then its CSL Seqirus business is the world’s second-largest influenza vaccine manufacturer.
And its CSL Vifor business is a global leader in iron deficiency and iron deficiency anaemia therapies.
Its position could well grow stronger, too. There will also be an ongoing need for immunoglobulin, influenza vaccines, and plasma therapies, and CSL is well-placed to scoop up a lot of that demand.
The company is undergoing an aggressive cost-savings and restructuring plan. In FY26, the company delivered US$176 million in pre-tax savings, which was well ahead of schedule, with more in the works. CSL is aiming to achieve around US$500 million to US$550 million in annual pre-tax savings by late FY28.
For FY27, the company is guiding a return to growth, including a 5% increase in underlying NPAT, which signals an operational turnaround and bottom line recovery for a once struggling business.
The bear case for CSL shares
Key reasons for the sharp CSL sell-off earlier this year were a loss in confidence for CSL’s earnings trajectory, a weaker profit outlook thanks to a lower flu vaccine rate in the US, guidance downgrades, and the sudden exit of its CEO in February.
The combination, especially within a short period of time, has raised questions about the company’s stability and forward earnings visibility.
Management called FY26 the year of a huge financial reset and flagged FY27 as the year for growth. But forward guidance of a 5% increase in its NPAT suggests a slow return to growth rather than an explosive one.
There is the potential that CSL’s ability to generate growth and profit now relies on its aggressive cost-cutting plan rather than true business expansion.
And let’s not forget the huge operational headwinds the company faced in FY26. These are still in the works. Elevated costs, logistic and shipping issues, softer US vaccine demand, and the cost of its latest restructure are headwinds that are likely to continue at least for the near term.
Then there is the CSL share price itself. After storming over 110% higher over the past four months, some are questioning whether the rebound is overdone, and whether CSL shares have climbed too high, too quickly.
My verdict
When I look at the short term, I’m concerned that CSL shares have rebounded fast over a short period of time. I think there is potential that the shares have raced too far ahead of value, and I wouldn’t be too surprised to see that profit-taking investors step in over coming weeks and send the shares tumbling south again.
It looks like the latest rally assumes that the growth picture will unfold without a hitch, and that a gradual and consistent path to recovery is likely.
Any indication that the company is not able to maintain the growth momentum it expects for FY27 could trigger a crash in confidence and widespread selling.
But, if I look at the broader picture, I’m a little more positive.
It looks like the worst is over for CSL shares.
Management’s structural reset, cost efficiency plans, strong market position, and demand for its products suggest the company is finally getting its ducks back in a row.
To me, it looks like the long-term road to recovery is now underway for CSL, although I expect a few bumps along the way.
What do the experts think?
If we look at expert outlooks, sentiment is mostly positive, but there are mixed messages about whether there is much more upside ahead for CSL shares over the next 12 months.
TradingView data shows that 11 out of 19 analysts have a buy/strong buy rating on the ASX healthcare shares. And another eight have a neutral stance.
But the average $187.52 target price implies around a 5% downside at the time of writing.
The team at Ord Minnett has an accumulate rating on CSL shares. The broker said it thinks the company’s Behring business can deliver stronger growth through FY27 to FY29.
Morgan Stanley is also positive on the shares with a buy rating and a $182 target price. The broker is also positive about improvement out of CSL’s Behring business, which it identifies as the company’s key group earnings driver.
