Shares of MannKind Corporation (MNKD) rose 8% on Wednesday after the company reported 17% growth in total revenue to $82.13 million, thanks to significant growth in its Afrezza inhaled insulin sales.

Afrezza revenue rose 23% to $18.49 million in the three months through the end of September, owing to higher prices and demand, while royalties rose to $33.32 million. Revenue from the V-Go insulin delivery patch, however, slipped 19% to $3.8 million due to low demand.

Q3 Performance

MannKind’s adjusted earnings per share came in at $0.07, up from $0.06 in the corresponding quarter of 2024, and above an analyst estimate of $0.02, according to data from Fiscal AI.

The company ended the quarter with cash, cash equivalents, and investments of $286.3 million, after utilizing approximately $133.2 million and borrowing an additional $250 million to fund the acquisition of scPharmaceuticals, which was completed in October.

The acquisition is expected to accelerate MannKind’s revenue growth with the addition of Furoscix to its portfolio. Furoscix is used to treat fluid overload in adult patients with chronic heart failure (CHF) and chronic kidney disease (CKD).

“The acquisition of scPharmaceuticals marks a significant expansion of our commercial capabilities and is expected to accelerate growth of our product revenues and build upon our commitment to delivering innovative, patient-centric therapies,” said Michael Castagna, CEO of MannKind.

The company has now submitted a supplementary application to the FDA for approval of Afrezza in the pediatric population aged four to 17 years. The agency is expected to make a decision on the application by May 29, 2026.
