Margins improve, but device growth still needs proof

01 Running thesis

Better margins, harder proof

Merit is in a cleaner spot than it was a few years ago. Full-year 2025 sales were $1.516 billion, up 11.8%, and gross margin rose to 48.7%. In Q1 2026, operating margin reached a record 19.7%. That supports the bull case that the Continued Growth Initiatives program is doing real work.

The next test is growth quality. Merit has bought useful assets, including View Point Medical in oncology, C2 CryoBalloon in endoscopy, Cook Medical lead management products, and Biolife assets. The View Point deal is the clearest new swing. Management says it triples the addressable breast biopsy market and could add about $15 million of revenue in 2027, growing 20% with 70% gross margins.

The bear case is not broken. OEM sales fell 14% year over year in Q1 2026 because of inventory destocking tied to product transfers to Tijuana. Management expects OEM to return to mid-single-digit growth in Q2, based on early orders. Investors need to see that happen, not just hear it promised.

Tariffs also keep the story from being simple. A Supreme Court ruling may help Merit recover some tariff costs, but the administration can challenge reimbursement through May 2026. That leaves the projected roughly $15 million 2026 tariff impact unresolved. The stock deserves credit for margin progress, but the proof points are still in front of it.

Apr 2026Q1 2026 strengthened the margin story, with operating margin reaching a record 19.7%. The View Point Medical acquisition also gave oncology a clearer 2027 growth path.
Apr 2026Merit changed revenue reporting to Foundational and Therapeutic categories. Foundational was about two-thirds of 2025 revenue, while Therapeutic was about one-third.
Apr 2026OEM sales fell 14% year over year in Q1 because of inventory destocking tied to product transfers. Management expects a Q2 recovery to mid-single-digit growth, so this is a watch item.
Apr 2026Risk disclosures added more detail on tariffs, the Middle East conflict, shipping disruption, and a Renal Class I recall. Management expects the recall to be financially immaterial for 2026.
Feb 2026FY2025 results supported the operating plan, with revenue of $1.516 billion, up 11.8%, and gross margin of 48.7%. Endoscopy grew 33.0% for the year.
Feb 2026Merit sold the DualCap product line for $28 million. The move made the portfolio cleaner, but it did not change the central thesis by itself.
Oct 2025The CEO transition to Martha G. Aronson was completed, reducing leadership uncertainty. Q3 results also showed strong gross margin and added C2 CryoBalloon to the endoscopy portfolio.
Jul 2025WRAPSODY revenue expectations for 2025 were cut to $2 million to $4 million after a reimbursement filing delay. Lower tariff cost expectations helped offset some of that pressure.
02 Business model

Many small tools for serious procedures

Merit makes and sells medical devices used by doctors during interventional, diagnostic, and therapeutic procedures. These are not consumer products. They are tools used in hospitals, clinics, and procedure rooms, often in areas like cardiology, radiology, oncology, critical care, and endoscopy.

The business has two broad revenue buckets. Foundational products are access and enabling tools, and they represented about two-thirds of 2025 revenue. Therapeutic products treat disease more directly, and they represented about one-third of 2025 revenue. Therapeutic products are where Merit is trying to add more growth through oncology, endoscopy, renal, and cardiac therapies.

This model can work well when Merit sells proprietary devices, improves factories, and folds acquired products into its sales force. It can break when hospital demand slows, OEM customers reduce inventory, shipping is delayed, tariffs lift costs, or recalls create operational noise.

03 Product portfolio

Where the growth can come from

Cash cow

Foundational access and enabling products

These products help doctors get into the body and perform procedures safely. They made up about two-thirds of 2025 revenue, so they fund much of the company.

Growth engine

Oncology, SCOUT, and View Point Medical

The View Point Medical acquisition added the OneMark Detection Imaging System and tissue markers. Management says the deal triples Merit's addressable breast biopsy market.

Growth engine

Endoscopy, EsophyX Z+, C2 CryoBalloon, and Resilience TTS

Endoscopy sales grew 33.0% in 2025. The newer C2 CryoBalloon technology and U.S. launch of the Resilience TTS Esophageal Stent add more products for digestive disease care.

Option

WRAPSODY

WRAPSODY is a commercial growth target for 2026, with management aiming for $7 million of revenue. Reimbursement timing hurt the early launch, so tracking sales matters.

Steady

Cardiac therapies and lead management

Merit added Cook Medical's lead management portfolio and Biolife assets. These deals helped expand cardiac therapy sales and give the company more products to sell into existing hospital channels.

Steady

OEM products

Merit also sells to other medical device companies. This can be useful volume, but Q1 2026 showed the risk when customers reduce inventory.

04 Business segments

Two buckets now matter

Foundational67%modest
Therapeutic33%growing fast

Merit now reports revenue as Foundational and Therapeutic. The mix below uses management's Q1 2026 disclosure that Foundational was about two-thirds of 2025 revenue and Therapeutic was about one-third.

05 Risk factors

What could trip the plan

Tariff refund risk

Medium impact · Medium odds

Merit still has a projected roughly $15 million 2026 tariff headwind. The Supreme Court ruled that some IEEPA tariffs were not authorized, but the company said the administration can still challenge reimbursement through May 2026. If refunds are delayed or denied, margin gains could be harder to keep.

We watchUpdates on tariff refund filings, final recovery amounts, and any change to 2026 cost guidance.

OEM destocking lasts longer

Medium impact · Medium odds

OEM sales fell 14% year over year in Q1 2026. Management blamed temporary U.S. inventory destocking tied to product line transfers to Tijuana and expects mid-single-digit growth in Q2. If that recovery misses, the growth story weakens.

We watchQ2 2026 OEM growth versus management's mid-single-digit target.

View Point integration misses

Medium impact · Medium odds

The View Point Medical deal is important because it expands oncology and could bring about $15 million of 2027 revenue at 70% gross margins. That upside depends on Merit integrating the product, training sales teams, and winning customers. A slow start would reduce the value of the deal.

We watch2027 oncology revenue growth, OneMark sales commentary, and gross margin contribution from View Point.

Recall and quality control pressure

Medium impact · Low odds

A recent Renal platform supply chain issue led to a Class I recall. Management expects the 2026 financial impact to be immaterial, but Class I recalls are serious because they involve a risk of severe harm. More quality issues could hurt trust with hospitals and regulators.

We watchFDA recall updates, new quality system findings, and any change to management's immaterial-impact view.

APAC and shipping disruption

Low impact · Medium odds

International sales face macro pressure in APAC. The Middle East conflict also created fuel surcharges and shipping issues, and Merit said about $1.5 million of Q1 revenue was left on the table because shippers could not pick up product. These are not thesis-breaking today, but they can chip away at growth.

We watchAPAC sales trends, freight surcharges, and any repeated revenue deferrals tied to shipping.
