Biogen Stock Rises on Q2 Beat, Raised Revenue Outlook

Biogen (BIIB) reported second-quarter results that beat analyst expectations on both revenue and adjusted earnings per share (EPS). Revenue came in at $2.7 billion, up 3% year over year, while adjusted EPS was $3.60. Analysts had forecast $2.4 billion in revenue and $3.17 in adjusted EPS.

The company's growth portfolio of medicines drove the top-line improvement, with revenue from those drugs jumping 24% year over year to $1.06 billion. However, adjusted net income fell to $536 million from $803 million a year ago.

Biogen also updated its full-year guidance. It now expects revenue to rise at a mid-single-digit percentage rate over 2025, a reversal from its previous expectation of a decline at roughly the same rate. Meanwhile, it lowered its adjusted net income guidance to $12-$13 per share from $14.25-$15.25.

Despite the profit guidance cut, the stock rose nearly 2% on the day, outperforming the S&P 500's 0.2% gain. Investors appeared to focus on the revenue beat and improved top-line outlook.

Biogen's results show that its strategic pivot toward a growth portfolio of medicines is gaining traction. The 24% revenue jump from these drugs suggests the company is successfully transitioning away from older, declining products.

The improved revenue guidance is a key positive signal. Previously, Biogen expected a revenue decline, but now it forecasts growth. This shift indicates that management's strategy is working better than anticipated.

While the profit guidance cut might seem concerning, the market's muted reaction suggests investors are willing to accept lower near-term earnings in exchange for a stronger long-term growth trajectory. This is typical for companies undergoing a turnaround.

For investors, the key question is whether Biogen can sustain this momentum. If the growth portfolio continues to deliver, the stock could see further upside. However, the lower profit outlook means near-term earnings will be under pressure.
