CSL Limited (ASX:CSL) Stock Outlook 2026: Is the Biotech Giant Finally a Buy After a 35% Sell-Off?

As of 9 December 2025

CSL Limited, long considered one of the most reliable growth names on the ASX, has just lived through one of the ugliest years in its listed history. After profit downgrades, a delayed spin-off, falling US vaccination rates and a shareholder revolt over executive pay, the stock is trading far below its early‑2025 highs.

Yet underneath the market drama, earnings are still growing, the balance sheet remains strong, and analysts – almost unanimously – still see upside.

This article pulls together the latest news, forecasts and analysis on CSL shares as at 9 December 2025, to help investors understand what has changed, what hasn’t, and what to watch into 2026.

CSL share price today: bruised but off the lows

On 9 December 2025, CSL shares were trading around A$184–186, leaving the company with a market capitalisation close to A$90 billion. ^[1]

Over the past 12 months:

The share price has fallen roughly 35–36% from its 52‑week high of A$288.33 reached on 8 January 2025. ^[2]
CSL hit a 52‑week low of A$170.77 on 29 October 2025 and has only modestly recovered since then. ^[3]
Commentators at Rask and The Motley Fool estimate the stock is down about 34–35% in calendar 2025 alone. ^[4]

This is a stark reversal for a company that for years traded on a premium multiple and was widely regarded as a “sleep‑well‑at‑night” compounder.

What went wrong in 2025?

1. Seqirus spin‑off, job cuts and a shock sell‑off in August

The first big shock came on 19 August 2025, when CSL reported its FY25 results and unveiled a sweeping restructure:

Reported net profit after tax (NPAT) rose 17% on a constant currency basis to about US$3.0 billion, while underlying NPATA climbed 14% to US$3.3 billion. ^[5]
At the same time, management announced plans to:
- Spin off the underperforming Seqirus vaccine division and list it separately on the ASX in early FY26.
- Cut up to 3,000 jobs globally and reduce its non‑US workforce by up to 15%.
- Close 22 US plasma collection centres and consolidate R&D operations. ^[6]

Despite the solid earnings growth, the combination of a complex spin‑off, big job cuts and guidance that fell slightly short of market expectations sent CSL shares down around 15% in a single session, wiping tens of billions from its market value. ^[7]

2. October AGM: guidance cut, spin‑off delayed and a second strike on pay

The second wave of selling arrived at the 28 October 2025 AGM in Melbourne:

CSL cut its FY26 guidance, trimming expected revenue growth from 4–5% to just 2–3%, and NPATA growth from 7–10% to 4–7%, citing a sharper‑than‑expected fall in US influenza vaccination rates. ^[8]
Management also delayed the planned Seqirus spin‑off, blaming “heightened volatility” in its key US vaccine market and an unprecedented drop in flu immunisation rates. ^[9]
Shareholders delivered a second strike against the company’s remuneration report, with more than 40% of votes opposing executive pay plans. A spill resolution was put but ultimately defeated, so the board survived – narrowly. ^[10]

The combination of weaker guidance, a shelved spin‑off and governance angst over pay saw CSL slump another ~16% to a seven‑year low near A$170. ^[11]

By early November, financial press estimated around A$55 billion had been wiped from CSL’s market value compared with its recent peak. ^[12]

Under the hood: CSL’s core business is still growing

The brutality of the share price move contrasts with what is still, fundamentally, a growing business.

FY25 results: plasma and rare disease still doing the heavy lifting

For the year to 30 June 2025, CSL delivered: ^[13]

NPAT: US$3.0 billion, up 17% at constant currency.
NPATA: US$3.3 billion, up 14%.
CSL Behring revenue: US$11.2 billion, up around 6% at constant currency.
- Immunoglobulin sales grew about 7% to over US$6.0 billion.
- Haemophilia product sales rose ~13%, helped by gene therapy HEMGENIX and strong demand for IDELVION and plasma‑derived therapies.
- Albumin sales increased ~7%, with encouraging signs in China.
Plasma collections continued to increase, and the rollout of RIKA plasmapheresis devices and the “iNomi” individualised nomogram was completed, helping reduce cost per litre of plasma and support margin expansion over time.

CSL’s first half‑year result for FY25 had already shown NPAT of roughly US$2.0 billion, underlining how profitable the core plasma and nephrology franchises remain despite headwinds in vaccines. ^[14]

Strategic reset: simplification and cost savings

At the AGM and in the 2025 annual report, management outlined a plan to simplify the group and free up at least US$500 million (around A$550 million) in savings by FY28: ^[15]

Consolidate R&D into six core sites and improve translational research efficiency.
Bring CSL Behring and CSL Vifor commercial and medical operations together to remove duplication.
Streamline corporate overheads and lean more heavily on the plasma network’s economies of scale.

Those savings are intended to be reinvested into the most promising growth initiatives, including next‑generation plasma products, rare disease therapies and nephrology treatments.

Fresh headlines this week: audit scrutiny, gene therapy data and buybacks

The last few days have brought a cluster of new developments that matter for CSL shareholders.

1. ANAO audit and vaccine contract headlines

On 9 December 2025, CSL shares slipped around 1% in early trade after the Australian National Audit Office (ANAO) published a critical report into a federal government deal with CSL’s Seqirus unit. ^[16]

Key points from the ANAO and local press coverage:

A roughly A$1 billion arrangement with Seqirus to build and operate a new vaccine manufacturing facility in Melbourne was found to lack clear evidence it offered value for money, with insufficient analysis of alternatives or benchmark costs. ^[17]
The report criticised planning around the contract’s conclusion in 2030 and suggested the procurement process drifted from its original goal of exploring innovative vaccine supply strategies. ^[18]
Commentators noted the findings add to a “bad news” run for CSL in a year marked by job cuts and guidance downgrades, even though the new facility still underpins Australia’s domestic supply of anti‑venoms, Q‑Fever vaccine and surge flu capacity. ^[19]

For now, the issue is more reputational and political than financial, but it reinforces the scrutiny on Seqirus just as CSL is trying to reset expectations for that division.

2. New HEMGENIX data and China albumin optimism

On 7 December 2025, CSL reported positive long‑term durability and safety results from its hemophilia B gene therapy HEMGENIX. Despite the encouraging clinical data, the share price “inched down” on the day amid broader bearish sentiment. ^[20]

Around the same time, Jefferies analysts flagged an expected improvement in CSL’s albumin sales in China in the second half of FY26, a key data point for investors worried about pricing pressure in that market. ^[21]

Together, these headlines highlight a tension that runs through the whole CSL story right now: the long‑term scientific and commercial pipeline looks strong, but the market is focused on near‑term cyclical hits to vaccines and sentiment.

3. On‑market buyback progress

CSL has an on‑market share buyback program under way as part of a broader capital management plan flagged in August, with a multi‑year buyback to be reintroduced in FY26. ^[22]

A TipRanks news update on 8 December confirmed that the company is continuing to repurchase shares on‑market, framing it as a tool to “manage capital and enhance shareholder value” at a time when the stock trades well below historical multiples. ^[23]

The buyback can modestly support earnings per share and signals management’s confidence in the long‑term value of the business, though it doesn’t change the fundamental growth questions around Seqirus.

CSL’s 2026 guidance and longer‑term growth outlook

FY26: a “reset year” with slower growth

CSL now describes FY26 as a reset year. Current guidance and commentary imply: ^[24]

Revenue growth: 2–3% over FY25 at constant currency, down from the earlier 4–5% outlook.
NPATA growth: 4–7%, versus the previous 7–10% range.
Seqirus: Lower contribution from avian influenza and COVID‑19 work, plus weaker US flu vaccination rates, will offset stabilisation in core seasonal influenza revenue.
CSL Behring: Expected to continue delivering robust demand for immunoglobulin and haemophilia therapies, aided by efficiency gains from the plasma network.
CSL Vifor: Management expects to maintain leadership in iron deficiency and continue building the nephrology franchise; drugs such as TAVNEOS and FILSPARI are highlighted as growth drivers.

At the AGM, management also told investors to expect high single‑digit NPATA growth in FY27 and FY28, reflecting uncertainty in the US influenza market but ongoing strength in the plasma and nephrology segments. ^[25]

External forecasts out to 2030

Third‑party models broadly align with a “moderate growth” picture once the vaccine business stabilises:

Simply Wall St forecasts earnings growth of around 10% per year over the next few years, with revenue growing ~4–5% annually and return on equity moving toward ~17%. ^[26]
Retail‑focused analysis from outlets like The Motley Fool discusses potential compounded earnings growth out to 2030, anchored in plasma, rare disease and nephrology, while acknowledging that vaccines and governance issues could keep the share price volatile in the near term. ^[27]

The core takeaway: CSL is no longer a 15–20% “automatic” grower, but consensus still assumes mid‑ to high‑single digit profit growth, with upside if Seqirus stabilises sooner than feared.

What do analysts think right now?

Despite the rough year, professional analysts remain overwhelmingly constructive on CSL.

Broker and consensus views

TipRanks shows a “Strong Buy” consensus based on 12 recent analyst ratings: 9 Buy, 3 Hold and no Sells. The average 12‑month price target is A$246.94, implying roughly 34% upside from around A$184.10, with a high target of A$286.04 and a low of A$197.10. ^[28]
A recent roundup of Australian broker commentary notes that Macquarie and UBS both rate CSL a buy with price targets around A$275, implying potential upside of about 50% if the stock can recover toward prior valuation levels. ^[29]
Morningstar assigns CSL a narrow economic moat, reflecting its strong plasma franchise and scale advantages, and recently cut its fair value estimate modestly to about A$295, still well above the current share price. Analysts there argue that Seqirus headwinds are temporary and that margins should improve as plasma efficiency gains flow through. ^[30]

Retail investor platforms and newsletters are more divided in tone, but even cautious commentators generally frame CSL as a high‑quality business experiencing a painful but likely temporary earnings reset rather than a broken franchise. ^[31]

Valuation: from “growth at any price” to something closer to value

For the first time in many years, CSL is trading on multiples that look almost… normal.

Trailing P/E: Around 20–23x based on a share price near A$185.50 and trailing diluted EPS of roughly A$8.16. Several data providers put the P/E between 19x and 23x, compared with mid‑30s multiples over much of the past decade. ^[32]
Price-to-sales: About 3.8x using current market cap and FY25 revenue, versus nearer 5–6x in prior years. ^[33]
Dividend yield: Approximately 1.9% for 2025 (vs ~1.4% in 2024), with a 2025 final dividend of 162 US cents (about 245 Australian cents) per share and an interim dividend of 130 US cents (about 207 Australian cents), all unfranked. ^[34]

Some valuation services note that CSL’s current P/E is close to the low end of its 10‑year range, suggesting a market that has sharply recalibrated its expectations for future growth. ^[35]

Whether that re‑rating is enough will depend on how convincingly management can stabilise Seqirus and deliver on the cost‑saving and growth plans in 2026–2028.

Key dates CSL shareholders should watch in 2026

If you hold CSL shares – or are thinking about them – the next 12 months have a packed calendar.

From CSL’s own financial calendar, dividend announcements and third‑party data: ^[36]

Operational and results dates

11 February 2026 – Half‑year FY26 results and interim dividend announcement (10:00–12:00 local time).
18 August 2026 – Full‑year FY26 results and final dividend announcement.

Dividend‑related dates (current indications)

9 March 2026 – Expected ex‑dividend date for the interim FY26 dividend (ASX line).
11 March 2026 – Record date for the interim dividend.
8 April 2026 – Expected payment date for the interim dividend.
9 September 2026 – Expected ex‑dividend date for the FY26 final dividend.
10 September 2026 – Record date for the final dividend.
2 October 2026 – Final dividend payment date. ^[37]

For holders of the US‑listed ADR (CSLLY), related ex‑dividend dates and payout timings around March and October 2026 are also already being flagged by dividend‑focused services. ^[38]

These dates matter because they will be key checkpoints for:

Updated guidance on Seqirus and vaccination trends.
Progress on cost‑saving measures and R&D simplification.
Any resuscitated plans for a Seqirus spin‑off once markets calm.

Main risks to the CSL investment case

Even at a lower share price, CSL is not risk‑free. Key issues investors are watching include:

US flu vaccination trends
CSL and independent analysts expect US flu vaccination rates to fall about 12% overall and 14% in the over‑65 cohort in the current season, a sharp reversal after a heavy flu year. That’s the main reason for the Seqirus profit squeeze and guidance cut. ^[39]
Seqirus spin‑off uncertainty
The decision to delay the spin‑off until volatility subsides creates a cloud over the vaccine business. If conditions remain weak, CSL may need to revisit the structure or timing of any future separation. ^[40]
Governance and shareholder trust
The second remuneration strike and the failed board spill motion show a clear gap between shareholder expectations and board decisions on pay. Rebuilding trust will require consistent communication and delivery on medium‑term targets. ^[41]
Regulatory and political noise
The ANAO’s value‑for‑money criticism of the Seqirus vaccine facility deal could lead to closer scrutiny of CSL’s public‑sector contracts, even if the operational importance of the plant is not in doubt. ^[42]
Execution risk on restructuring
Cutting thousands of jobs, consolidating R&D, closing plasma centres and integrating Vifor is complex. Any missteps could slow new product launches, erode morale or offset the promised US$500m+ in savings. ^[43]

Bottom line: CSL in 2026 – broken story or rare opportunity?

Stepping back, CSL in December 2025 is not the same market darling it was a year ago:

Growth is slower, at least for a few years.
Vaccines are a real problem child.
Governance and political noise have risen.

Yet:

The core plasma and rare disease franchises are still growing and highly profitable. ^[44]
The balance sheet remains solid, and dividends and buybacks are increasing. ^[45]
Almost all major analysts still see material upside from current levels, with average 12‑month price targets in the mid‑A$240s to high A$200s. ^[46]

For long‑term investors, CSL now looks less like an untouchable growth champion and more like a high‑quality, cyclical healthcare stock going through a messy reset. The key question is whether 2026 becomes the year management proves that Seqirus is fixable, cost savings are real and plasma margins can keep grinding higher.

If they succeed, 2025 may eventually be remembered as the year the market overreacted. If they don’t, today’s “cheap for CSL” multiple could turn out to be justified.

Either way, the coming reporting cycle – starting with half‑year results on 11 February 2026 – will be pivotal.
