Humana, a prominent insurer, is currently in a state of flux as its chief financial officer, Susan Diamond, is set to step down. This decision comes at a time when the company is grappling with the challenge of managing high medical costs in Medicare Advantage, which has a significant impact on its finances. Diamond, who has held the top finance position at Humana since 2021, will remain with the insurer in an advisory role until the end of next year.

Humana's Financial Leadership Transition

Diamond's Departure and Her Impact

Susan Diamond's decision to leave Humana after 18 years is a significant event. She has played a crucial role in the company's financial management during a challenging period. Her expertise and leadership have been instrumental in navigating the insurer through various financial situations. With her departure, Humana now faces the task of finding a suitable replacement to continue driving the company's financial success.

During her tenure, Diamond has overseen important financial decisions and strategies that have shaped Humana's financial position. Her departure will leave a void that needs to be filled by a capable individual who can understand the intricacies of the healthcare industry and the insurer's financial operations.

Mellet's Appointment and Her Qualifications

Celeste Mellet, the chosen successor to Diamond, brings a wealth of experience to Humana. She comes from Global Infrastructure Partners and has previously worked at investment banks Evercore and Morgan Stanley, as well as mortgage financier Fannie Mae.

Humana CEO Jim Rechtin praised Mellet, stating that she is a highly accomplished CFO with first-hand experience navigating dynamic and highly regulated industries. Her proven track record of working with cross-functional teams makes her well-suited to drive improved performance throughout the complex organization.

Financial Turmoil at Humana

Humana has been facing financial turmoil in recent months. In April, the company pulled its profit outlook for 2025 due to declining payment rates in Medicare Advantage. Payers in the privatized Medicare program are managing increased medical spending among beneficiaries, which has put pressure on Humana's finances.

The insurer is also facing a significant drop in MA star ratings for next year, which could have a substantial impact on its financial performance. In late October, Humana sued the HHS over its star ratings, arguing that federal regulators calculated the scores in an arbitrary and capricious manner.

Progress in Improving Financial Position

Despite the challenges, Humana has made some progress in improving its financial position in the third quarter. The company posted better results than analysts anticipated and boosted its 2025 earnings guidance.

On Tuesday, Humana reiterated its adjusted profit guidance for this year, expecting at least $16 per share. The insurer also expects adjusted profit for 2025 to be "at least in line with final 2024 results." These positive developments give hope for the company's future financial performance.
