EPS guidance of $5.70 at the midpoint of the projection range was also reiterated by the company. For the last three months, the adjusted profit per share was $1.32, which was higher than expected.

Staffing concerns slowed the company's growth in the second quarter, maintaining revenue at 3%. The total revenue of $7.8 billion was slightly lower than expected.

Ventilator sales, which had soared last year, began to decline as the pandemic faded. As a result, the medical surgical portfolio's revenue increased by only 1%. Medical surgical income increased by 6% when ventilators were excluded.

Sales in the United States declined 1% in the second quarter, to $4 billion, accounting for 51% of overall revenue. Non-U.S. developed market revenue increased by 1%, accounting for 32% of total sales.

The increase in overall sales was driven by emerging markets, which grew by 17%.
