Guggenheim sets Sionna stock Buy rating, $45 target

On Tuesday, Guggenheim initiated coverage on Sionna Therapeutics (NASDAQ:SION) with a Buy rating and a price target of $45.00, representing significant upside potential from the current trading price of $14.41. According to InvestingPro data, the stock has experienced notable pressure, declining over 42% year-to-date. The firm’s positive outlook is based on the potential of Sionna’s approach to treating cystic fibrosis (CF) through NBD1 stabilization, a method considered crucial for restoring function in ΔF508 CFTR mutants, which are common in CF patients.

The research conducted by Guggenheim suggests that Sionna’s lead candidates, SION-719 and SION-451, could significantly restore CFTR maturation and function. This restoration is expected when these candidates are used in conjunction with Sionna’s complementary CFTR modulators. While the company shows strong liquidity with a current ratio of 21.66, InvestingPro analysis reveals the company is not yet profitable, with negative EBITDA of $64.36 million in the last twelve months. The analysts believe that these therapies could address the unmet needs of CF patients by improving sweat chloride levels and percent predicted forced expiratory volume in 1 second (ppFEV₁) to near normal levels.

The potential for SION-719 and SION-451 includes use as an add-on to Trikafta, a leading CF treatment, which could provide insights into the synergistic clinical efficacy of NBD1 stabilization. Guggenheim’s review highlights Sionna’s proprietary CFHBE model, which predicts this synergy. However, the company’s preferred strategy is to develop a proprietary dual combination therapy that includes NBD1 stabilization and a complementary CFTR modulator.

If successful and approved, Guggenheim estimates that Sionna’s proprietary dual combination therapy could achieve up to $4 billion in unadjusted global peak sales. This figure is risk-adjusted to $1.4 billion, reflecting the inherent uncertainties in drug development and regulatory approval processes.
