"With our revenues growing nicely, we are focusing on our product pipeline where our INHALE-1 Phase 3 trial for Afrezza in pediatrics reached 50% enrollment at December 31, 2022 and our inhaled clofazimine will move into an adaptive Phase 2/3 study in the second half of 2023."

The increase in Afrezza^® net revenue was mainly a result of higher demand. V-Go was acquired in the second quarter of 2022. The increase in collaborations and services revenue reflected the fact that the manufacture of Tyvaso^® DPI for commercial sale had not yet commenced in the previous period. Royalties from United Therapeutics ("UT") for Tyvaso DPI continued to grow based on strong patient demand.

Afrezza gross margin in the fourth quarter of 2022 was 92% compared to 62% for the same period in 2021, mainly due to a decrease in cost of goods sold driven by lower inventory write offs, lower cost of production per unit and a higher amount of manufacturing activity in 2022 (which absorbed more cost to inventory). V-Go^® gross margin was 42% for the fourth quarter of 2022.

Cost of revenue – collaborations and services for the fourth quarter of 2022 was $12.0 million compared to $7.1 million for the same period in 2021, an increase of $4.9 million, primarily due to an increase in manufacturing activities associated with the production of Tyvaso DPI.

Research and development ("R&D") expenses for the fourth quarter of 2022 were $7.2 million compared to $3.9 million for the same period in 2021. This $3.3 million increase was primarily attributed to costs incurred to develop our product pipeline, including the Afrezza pediatrics clinical study (INHALE-1) and MNKD-101 (inhaled clofazimine).

Selling expenses for the fourth quarter of 2022 were $11.6 million compared to $13.5 million for the same period in 2021. This $1.9 million decrease was primarily attributable to the net impact of lower personnel-related costs associated with the first quarter of 2022 Afrezza sales force restructuring, and a pilot promotional effort aimed at primary care physicians that began in the fourth quarter of 2021 and ended in the third quarter of 2022, partially offset by V-Go promotional efforts.

General and administrative ("G&A") expenses for the fourth quarter of 2022 were $10.5 million compared to $9.2 million for the same period in 2021. This $1.3 million increase was primarily attributable to higher stock-based compensation and increased headcount.

Interest expense on financing liability was $2.5 million for the fourth quarter of 2022 and represented interest incurred on the sale lease-back transaction for our manufacturing facility in Danbury, CT, which was entered into in the fourth quarter of 2021.

Interest expense on notes was flat in the fourth quarter of 2022 compared to the same period in 2021 due to fixed interest rates and no changes in debt balances.

Afrezza net revenue increased year-over-year primarily due to higher price (including a more favorable gross-to-net adjustment), higher product demand, and a more favorable cartridge mix. Collaborations and services revenue decreased, primarily due to the completion of the R&D services associated with our collaboration with UT, which was partially offset by revenues associated with the manufacturing of Tyvaso DPI. As of December 31, 2022, $37.9 million of manufacturing revenue associated with Tyvaso DPI remains deferred and will be recognized as commercial product is sold to UT.

Afrezza gross margin for 2022 was 80% compared to 57% for the same period in 2021, driven primarily by a decrease in excess manufacturing capacity costs (as Tyvaso DPI was in commercial production in 2022), a decrease in inventory write offs and an amendment fee associated with our Insulin Supply Agreement in 2021. V-Go gross margin was 43% for 2022.

Cost of revenue – collaborations and services for 2022 was $41.5 million compared to $22.0 million for the same period in 2021, an increase of $19.5 million, primarily due to an increase in manufacturing activities for the production of Tyvaso DPI.

R&D expenses for 2022 were $19.7 million compared to $12.3 million for the prior year. This $7.4 million increase was primarily attributable to costs incurred to develop our product pipeline, including INHALE-1 and MNKD-101.

Selling expenses for 2022 were $53.8 million compared to $45.5 million for the prior year. This $8.3 million increase was primarily attributable to the primary care pilot program, elimination of the Thyquidity co-promotion (which permitted some expenses associated with the sales force to be recognized as cost of revenue for collaborations and services in the same period of 2021), V-Go promotional efforts after the acquisition in the second quarter of 2022, and partially offset by the net favorable impact of personnel-related costs associated with the Afrezza sales force restructuring in 2022.

G&A expenses for 2022 were $37.7 million compared to $31.9 million for the prior year. This $5.8 million increase was primarily attributable to higher stock-based compensation, increased headcount, and higher professional fees.

Interest expense on the financing liability was $9.8 million for 2022 and represented interest incurred on the sale lease-back transaction for our manufacturing facility in Danbury, CT.

Interest expense on notes was flat for 2022 compared to 2021 due to fixed interest rates and no changes in debt balances.

Cash and cash equivalents and investments as of December 31, 2022 were $172.8 million.
