ResMed's growth slows as margins shrink and ventilator recall bites

Margin squeeze hits profits ResMed's operating margin fell to 30.7% from 33.7% a year earlier, and free cash flow margin dropped sharply. Higher research, supply chain and marketing costs, plus a $42 million safety charge, mean the company keeps less profit from each sale, which pushed shares down.
Margin decline is the core reason the stock dropped after earnings and is a key concern for future profitability.
Ventilator recall cuts sales ResMed suspended sales of its Astral ventilators after a serious safety recall. This removes about $75 million of expected revenue in fiscal 2027 and is a main reason the company's revenue forecast came in below what analysts expected, weighing on the stock.
The recall is a concrete, quantified headwind that directly explains the softer guidance and negative price reaction.
Soft FY27 guidance disappoints ResMed guided fiscal 2027 revenue to $5.75–$5.85 billion, below the $5.92 billion consensus. The shortfall, blamed on the ventilator recall and macro uncertainty like inflation in components and freight, caused a 7% share drop as investors worried about slower growth.
Guidance below expectations is a direct driver of the negative stock reaction and sets the growth outlook.
Divestiture and buybacks support focus ResMed is selling its MatrixCare software unit to Frazier Healthcare and buying Noctrix to expand into restless legs syndrome. It also raised its dividend 10% and plans over $1.85 billion in shareholder returns, including a $450 million accelerated share repurchase, signaling confidence and sharper focus on core sleep and respiratory care.
These capital actions show management's efforts to streamline and return cash, offering a positive counterweight to the margin and recall issues.

Wondfo's first-half profit and cash recovery offset a decade-first annual loss

First loss in a decade as policy squeezes demand and prices Wondfo's 2025 revenue fell 31.91% and it posted its first loss since listing, hit by centralized procurement and DRG/DIP payment rules that cut test volumes and prices. The stock hit a new low, down about 72% from its peak, showing how badly policy pressure hurt the core testing business.
Explains the main force behind the stock's slump and why investors are worried.
Buyback and controlling-shareholder purchases signal insider confidence The company approved a 30-60 million yuan buyback, and controlling shareholder Wang Jihua bought 1.156 million shares for about 20 million yuan, completing her 20-40 million yuan plan. Insiders putting real money in suggests they see the shares as undervalued, which can support the price.
Shows concrete capital actions that counter the negative news and support the stock.
First-half profit and cash flow swing back to positive Wondfo reported first-half 2026 revenue of 1.039 billion yuan and net profit of 123 million yuan, with operating cash flow turning from a 56.31 million yuan outflow to a 423.99 million yuan inflow. Gross margin edged up, and overseas molecular diagnostics revenue jumped 228%, suggesting the worst may be passing.
This is the key new evidence that the business is recovering, directly answering why the stock may be moving.
Seven new chemiluminescence registrations widen product range Wondfo received seven chemiluminescence device registration certificates covering liver, islet and heart tests. These add to its product lineup and support its push into the larger in-vitro diagnostics market, though the company says the revenue impact cannot yet be predicted.
Shows new product momentum that could drive future growth, a fresh positive for the stock.
