Allergy Therapeutics wins broker “seal of approval” as Germany launch of Grassmuno begins and revenues rise

Allergy Therapeutics PLC has received a fresh vote of confidence from broker Cavendish, following a trading update that showed early revenue growth and a major regulatory milestone in Germany: the approval and commercial rollout of its new grass pollen immunotherapy, Grass MATA MPL, marketed as Grassmuno.

In practical terms, the update signals two things investors usually want to see at the same time: momentum in the numbers and progress on a long-running strategic pivot. For Allergy Therapeutics, that pivot has been about modernising its German portfolio as the market moves away from older, unregistered products and toward therapies that meet current regulatory expectations.

What Cavendish said, and why it matters

According to a broker note shared publicly, Cavendish reiterated a “buy” rating on Allergy Therapeutics and referenced a 13p price target. The broker pointed to (1) the company’s early revenue growth and (2) the start of commercial sales in Germany for the newly approved grass pollen treatment as key positives.

Broker commentary can move markets for smaller listed healthcare companies, especially when it ties an investment view to specific operational milestones. Here, the milestone is not vague. Germany is widely viewed as one of the most important allergen immunotherapy (AIT) markets in Europe, and a new authorised product launch can materially reshape a company’s positioning—particularly if competitors face portfolio disruption due to tightening regulations.

The trading update: revenue growth despite a difficult transition

Top-line performance in the six months to December 2025

For the six months ended 31 December 2025, Allergy Therapeutics indicated revenue of about £36.3 million, up from roughly £34.0 million a year earlier—equating to around 7% reported growth. Cavendish also pointed out that, on a constant-currency basis, the growth rate looked closer to about 3%.

That matters because the company is operating through a period where Germany has been moving away from certain unregistered allergen products. During any forced product transition, revenues can wobble. Growth in that context can be interpreted as a sign that the core business is holding up while the company reshapes its catalogue.

Why Germany is the key battleground

Germany isn’t just “another European market.” In allergen immunotherapy, it’s often treated as a bellwether because of its scale, prescribing culture, and regulatory influence. In the broker’s view, the most notable development in the period was the regulatory approval in Germany of Grass MATA MPL (Grassmuno), which it said paves the way for a broader rollout in Europe’s largest AIT market.

The company’s CEO described the approval as a pivotal moment, linking it to the approaching end of the German allergen ordinance TAV process, which is expected to reshape which products remain available in the market.

Grassmuno (Grass MATA MPL): why this launch is a big deal

A rare new entry in a mature category

Allergy Therapeutics has said it began commercialisation of Grassmuno in January, following German marketing authorisation granted in December. Notably, the update characterised this as the first new launch in the German subcutaneous immunotherapy market in 20 years—a statement that underlines how unusual meaningful new entries can be in this category.

When a market goes a long time without “new launches,” it typically means three things:

• High barriers to entry (clinical requirements, manufacturing standards, and regulatory scrutiny).
• Entrenched incumbents with established prescribing habits.
• Significant upside for a company that can place a differentiated, authorised product into routine practice.

While the commercial outcome will still depend on execution—pricing, physician adoption, distribution, and patient persistence—the approval itself is a meaningful de-risking event because it demonstrates the product meets the regulator’s expectations.

How this fits the “registered products” strategy

Investors following Allergy Therapeutics have heard a consistent theme: shifting from legacy or transitional products toward a portfolio that is more robust under today’s regulatory environment. In that storyline, Germany registration isn’t just a checkbox; it’s the foundation for expanding a modern product set and defending share as the market changes.

Chairman Peter Jensen highlighted another layer: achieving registration in Germany helps validate the company’s clinical trial methodology, which it believes can be applied to other allergy indications, such as birch and ragweed.

Financial position: cash, debt clean-up, and funding access

Cash at the end of December

Allergy Therapeutics reported a cash position of about £10.1 million at the end of December, compared with £12.8 million in June 2025. The company linked the reduction to the repayment of outstanding shareholder loans.

For readers who don’t live and breathe balance sheets, here’s the simple interpretation: a lower cash number isn’t automatically “bad” if it reflects deliberate debt repayment or financial housekeeping that reduces risk elsewhere.

Warrant exercises and debt repayment

The update also stated the company received £55 million from warrant exercises by shareholder lenders, which it used to clear financial debt.

This point is important because it suggests the company has been actively working to strengthen its capital structure. In small-cap biotech and specialty pharma, reducing debt pressure can make it easier to invest in launches, fund trials, and handle working-capital swings without constantly returning to the market for emergency financing.

Additional funding “headroom”

Allergy Therapeutics also said it has access to £70 million in uncommitted funding facilities while it explores strategic options.

“Uncommitted” matters because it typically implies facilities that are available but not necessarily guaranteed in all circumstances. Still, it provides a sense of optionality—especially valuable during launch periods, when inventory build, marketing, and distribution can create short-term cash demands before revenues catch up.

A potential Hong Kong dual primary listing: what that could mean

Another headline detail in the update was that the company is exploring a potential dual primary listing on the Hong Kong Stock Exchange.

Companies consider dual primary listings for several reasons:

• Broader investor access (especially in regions where healthcare and growth stocks may attract specialist capital).
• Liquidity potential if a new venue brings more active trading.
• Strategic visibility in markets that are relevant for future partnerships or commercial expansion.

That said, a listing exploration is not the same as a completed listing. Investors usually watch for concrete steps: advisers appointed, timetable guidance, regulatory filings, and clarity on costs and ongoing obligations.

Pipeline progress: the VLP Peanut program

Beyond the commercial story in Germany, the update referenced the company’s VLP Peanut program, described as a next-generation peanut allergy immunotherapy with encouraging interim results.

Peanut allergy remains a major unmet need, not only because it can be severe, but also because it affects quality of life for families managing risk in everyday settings like schools, restaurants, and travel. A successful therapy in this space can be commercially meaningful. However, it is also a complex development area where clinical outcomes, safety, dosing convenience, and long-term durability all matter.

At this stage, the key takeaway is that the company continues to invest in a pipeline that could create additional “shots on goal” beyond its current marketed portfolio.

Why the TAV transition could reshape competitive dynamics

One of the most strategic elements in the company’s commentary is the idea that regulatory tightening—often discussed in relation to the German allergen ordinance and the TAV process—could reduce the number of competitor products available if they do not meet requirements.

If that scenario plays out, companies with authorised, compliant products may be positioned to benefit from:

• Less crowded prescribing choices for physicians.
• Greater confidence among clinics and payers in regulated, standardised therapies.
• Improved share stability as the market consolidates around compliant portfolios.

This is one reason why brokers can treat an approval like Grassmuno as more than “just another product.” In a shifting regulatory landscape, compliance can become a competitive moat.

Operational execution: what investors will watch next

1) Evidence of early Grassmuno uptake

The first commercial signals investors often look for after a launch include early ordering patterns, physician feedback, and repeat purchasing. Even if initial volumes are modest, a positive trajectory can help build confidence in the broader rollout story.

2) Stability during the German product phase-out

The company has acknowledged that it is still managing the ongoing phase-out of unregistered products in Germany. Investors will watch whether revenues remain resilient as the product mix shifts further toward authorised offerings.

3) Margin and cost discipline

Revenue is only half the story. Launches can be expensive—sales teams, distribution, regulatory maintenance, medical education, and supply chain. The market typically rewards companies that can show a sensible balance: investing to grow while keeping cost escalation under control.

4) Pipeline milestones, especially VLP Peanut

Any new data, trial updates, or partnership signals around VLP Peanut could become meaningful catalysts because food allergy is a high-interest area for both investors and potential commercial partners.

5) Clarity on the Hong Kong listing pathway

If the company continues to explore a dual primary listing, investors will watch for concrete next steps, the strategic rationale, and any expected benefits to liquidity or funding access.

What this all means in plain English

If you strip away the stock-market language, the story looks like this:

• The company says it grew revenue in the latest half-year period, even while navigating a challenging transition in Germany.
• It has now secured a high-value regulatory approval in Germany and started selling a newly authorised grass pollen therapy (Grassmuno).
• A broker (Cavendish) responded by reaffirming a positive stance on the shares, pointing to these milestones and assigning a stated price target.
• The company has also outlined financial housekeeping (debt repayment supported by warrant exercises) and mentioned additional funding access and a possible Hong Kong listing exploration.
• Meanwhile, it continues to develop pipeline programs like VLP Peanut, which it says are showing encouraging interim signals.

Together, these points form a coherent investor narrative: stabilise and grow the base business, upgrade the portfolio under stricter rules, and open new growth avenues through launches, listings, and R&D.
