Mersana Therapeutics Implements Reverse Stock Split to Meet Nasdaq Listing Requirements

Mersana Therapeutics has announced a 1-for-25 reverse stock split to boost its stock price and maintain its Nasdaq listing. The move aims to meet the minimum bid price requirement. Analysts forecast an average target price of $5.00 with an upside of 1,132.74% from the current price of $0.41. The company's net cash used in operating activities was $29.3 million in Q1 2025, and collaboration revenue decreased to $2.8 million from $9.2 million in Q1 2024.

Mersana Therapeutics, Inc. (MRSN) has announced a 1-for-25 reverse stock split to boost its stock price and maintain its listing on the Nasdaq Global Select Market. The move aims to meet the minimum bid price requirement set by Nasdaq, which is $1.00 per share. The reverse stock split will reduce the number of outstanding shares from approximately 124.8 million to about 5.0 million, effectively increasing the per-share price.

The reverse stock split is set to take effect at 5:00 p.m. Eastern Time on July 25, 2025. Trading on a split-adjusted basis is expected to begin on July 28, 2025. The company will maintain its "MRSN" ticker symbol but will receive a new CUSIP number. Shareholders who would receive fractional shares due to the split will instead receive cash payments. Proportionate adjustments will be made to equity incentive plans and outstanding equity awards.

Analysts forecast an average target price of $5.00 with an upside of 1,132.74% from the current price of $0.41. This significant potential increase in share price is expected to attract investors and stabilize the stock's market performance. However, the company's financial health remains a concern, with net cash used in operating activities at $29.3 million in Q1 2025 and collaboration revenue decreasing to $2.8 million from $9.2 million in Q1 2024.

The biotech sector's broader volatility has been exacerbated by MRSN's collapse, with peers like Amgen (AMGN) also drifting lower. The reverse stock split has triggered a flight to safety as investors react to the optics of a desperate bid to avoid delisting. The company's negative P/E ratio (-0.42) and 52-week low of $0.2589 further amplify concerns about its ability to generate meaningful value from its ADC pipeline.

Technical indicators suggest short-term overselling but long-term bearishness. The RSI is in overbought territory, hinting at a potential bounce, but the 200D MA remains a towering hurdle. Traders should monitor the $0.31 intraday low as a critical support level. Leveraged ETFs like the SPDR S&P Biotech ETF (XBI) could offer directional exposure, aligning with MRSN's selloff.

Mersana Therapeutics' delisting gambit has failed to rally buyers, with the stock trading near its 52-week low. The lack of a clear catalyst for a rebound suggests the selloff may persist until the company delivers meaningful clinical or financial progress. Traders should watch the $0.31 support level and Amgen's (AMGN) move for sector-wide signals.

Investors would be wise to avoid aggressive long positions until the $0.4056 previous close retests as a potential entry point. The message is clear: MRSN's delisting risk and weak fundamentals have left the stock vulnerable to further declines.
