UBS has told investors that the recent slide in AstraZeneca PLC (LSE:AZN, NASDAQ:AZN) shares has gone too far, keeping its buy rating on the FTSE 100 drugmaker even after two clinical setbacks and speculation about a mega-merger. The stock has fallen roughly 15% since early July, when two...

LB Pharmaceuticals is on a tear. The IPO stock has more than tripled as investors watch its efforts in neuropsychiatric disorders.

Investing.com -- Jefferies initiated coverage of Braveheart Bio with a Buy rating and a $48 price target, implying roughly 75% upside from the stock’s prior closing price. The move comes after the company priced its initial public offering (IPO) at $18 per share earlier this month, raising $382.5 million in one of the largest biotech debuts of 2026.

Seaport Therapeutics just went public with a prodrug platform that has attracted board members from two of the biggest neuroscience acquisitions in recent history. The question is whether the same giants who funded those deals are already circling for a third.

Companies try to get deals done while regulators allow them. But are buyouts always a good idea?

There's a good reason why AstraZeneca tanked when merger rumors hit the Street.

Reports of talks were quickly disputed, but the prospect exposed the appeal — and antitrust risks — of combining two pharma giants.

Braveheart is one of five biotechnology firms that made plans to price an IPO this week, bringing in total what could ultimately be more than $1 billion from public investors.

According to a Reuters report, a senior source denied merger discussions between AstraZeneca and Bristol Myers Squibb.

AstraZeneca (NASDAQ:AZN) shares climbed around 6% on Wednesday after Reuters reported that there are “no discussions” between the company and Bristol Myers Squibb (NYSE:BMY) regarding a potential merger, contradicting recent speculation that had unsettled investors. The report eased concerns surrounding a deal that, if completed, would have created a pharmaceutical group valued at close to $400 billion.

A source close to the matter told Reuters there is "no deal" and there "never was a deal to be done" between the two drugmakers

Chief Executive Mike Doustdar’s comments come amid sector focus on M&A and after Novo Nordisk made two disclosures in recent days on its future pipeline that disappointed investors.

AstraZeneca (NASDAQ: AZN) and Bristol Myers Squibb (NYSE: BMY) are the two directly affected public companies; AZN bears the most immediate price risk given it absorbed a roughly 9% single-day selloff on Monday when the merger speculation first emerged, while BMY shareholders were widely viewed as the primary beneficiaries of any combination.

Citi has told clients that a large chunk of deal risk is already in AstraZeneca PLC's (LSE:AZN, NASDAQ:AZN) share price after Monday's sharp fall, while Deutsche Bank sees clear parallels with the drugmaker's Alexion acquisition five years ago. The two notes are the second-day response to a...

Even if a megamerger fails to materialize, investors stand to benefit from a wave of M&A activity in the biopharma sector.

Big drug companies have been buying scrappy biotechs to expand their pipelines, but the potential megamerger between AstraZeneca and Bristol Myers Squibb could flip that script.

Investors questioned whether combining AstraZeneca with Bristol Myers would strengthen growth enough to justify the financial and regulatory risks.

The UK drugmaker is reportedly talking to Bristol Myers Squibb about a nearly $400 billion tie-up, but investors are struggling to diagnose the logic.

The FTSE 100 index closed down 10.35 points, 0.1%, at 10,857.70.

One of the largest global pharma companies would be created if a deal were to materialise.

BMY surged roughly 6% in premarket trading on the news before fading; the stock is now trading near flat. The asymmetric price reaction captures the market's immediate verdict: AZN shareholders see a value-destructive deal, while BMY holders see a potential premium exit.

Bristol Myers Squibb stock is surging Monday following a report of a potential mega-merger with a competitor.

AstraZeneca stock took a nosedive Monday amid reports it's mulling a mega-merger with Bristol Myers Squibb.

A combination of the two pharmaceutical companies could create an entity valued at nearly $400 billion, according to the Financial Times

The merger would be one of the biggest pharma deals ever. AstraZeneca’s market capitalization stood at $264 billion as of Friday’s close, while Bristol Myers Squibb had a total valuation of $133 billion.

If maintained until close, the decline would be the stock’s biggest one-day percentage fall since the day of the 2024 U.S. presidential election.

The move would mark one of the industry’s largest ever deals and create the world’s fourth largest pharmaceutical company.

Investing.com -- AstraZeneca PLC (NYSE:AZN) and Bristol-Myers Squibb Company (NYSE:BMY) have held talks in recent months about a deal that would combine the companies into one, according to a Financial Times report.

AstraZeneca is plotting a $400bn (£300bn) merger with US rival Bristol Myers Squibb in a deal likely to raise fresh questions over the company’s ties to the UK.
