Progenics Highlights Additional Serious Concerns About Velan Capital, L.P.

Flags Velan’s Knowledge of Lantheus Transaction Weeks Before It Was Made Public

Raises Significant Concerns About Velan’s Questionable Securities Trading, Governance and Ethical Practices

Asks Velan’s Nominees if They Want to Be Associated with These Questionable Practices

Reminds Shareholders to SIGN THE COMPANY’S WHITE CONSENT REVOCATION CARD and to IGNORE VELAN’S GREEN CONSENT CARD

NEW YORK, Oct. 23, 2019 (GLOBE NEWSWIRE) -- Progenics Pharmaceuticals, Inc. (NASDAQ:PGNX) (“Progenics” or the “Company”), an oncology company developing innovative targeted medicines and artificial intelligence to find, fight and follow cancer, today issued the following letter that it intends to mail to shareholders, highlighting Velan Capital L.P.’s (“Velan”) knowledge of the Company’s proposed transaction with Lantheus Holdings, Inc. (NASDAQ:LNTH) (“Lantheus”) weeks before it was made public, which raises significant concerns about Velan’s questionable securities trading, governance and ethical practices. Additionally, Progenics urges Velan’s five nominees to consider if they want to risk their reputations and continue to be associated with someone that operates in Velan’s manner.

October 23, 2019

Dear Fellow Shareholder:

In the coming days, you will be asked to make an important choice regarding your investment in Progenics and the future of the Board of Directors of Progenics (the “Board”). As you contemplate your decision, we want to ensure you have the facts about Velan, its principal Bala Venkataraman, and its affiliates (collectively, the “Velan Group”) – specifically the facts we discuss below, which Progenics’ advisors recently learned. We have also provided an appendix below with a detailed timeline of Velan’s and Mr. Venkataraman’s known activities related to this matter.

In particular, Progenics is aware that Mr. Venkataraman and the Velan Group knew about – and expressed vehement opposition to – the proposed acquisition of Progenics by Lantheus (the “Transaction”) well in advance of the public announcement of the Transaction, and made significant trades in Progenics’ stock while aware of the potential Transaction. Specifically:

• On August 14, 2019, Mr. Venkataraman told a representative of the financial advisor to Lantheus in the proposed Transaction, that he knew that the firm was advising Lantheus with respect to the Transaction and that he was opposed to any such Transaction, notwithstanding that deal terms had not been finalized, much less announced, as of that time.
  
• On September 18, 2019, the date the Velan Group launched its consent solicitation, Mr. Venkataraman and his associate Deepak Sarpangal told two other representatives of Lantheus’ financial advisor in separate interactions during a conference hosted by the financial advisor that he knew about the Transaction – and which specific representative of the financial advisor was advising Lantheus – from two sources, one of whom was an investment banker. Mr. Venkataraman also told these representatives that the Velan Group opposed the Transaction and, in one instance, stated that he would spend millions of dollars to prevent a deal from taking place. At dinner that night at the financial advisor’s conference, members of the Velan Group, including Mr. Sarpangal, sat next to a Progenics director but did not raise the topic of the Transaction.

The public announcement of the Transaction did not occur until October 2, 2019 — seven weeks after Mr. Venkataraman first approached Lantheus’ financial advisor about his knowledge of the potential deal. During that seven-week period, armed with the non-public knowledge of the potential Transaction, the Velan Group actively traded in Progenics’ stock. They purchased an aggregate of 1,555,759 Progenics shares for a total purchase price of approximately $6.5 million and amounting to 1.73% of the Company’s outstanding shares.¹

The Velan Group’s Failure to Disclose this Information Was Deceitful to Shareholders, Misleading to the Proxy Advisory Firms and a Blatant Disregard of the Basic Disclosure Requirements of the Securities and Exchange Commission (the “SEC”)

The Velan Group had more than ample opportunities to disclose its knowledge of, and uninformed opposition to, the Transaction. For example, between August 14 and September 18, 2019 (the date Velan launched its consent solicitation), the Velan Group communicated privately to Progenics’ Board and Management, directly or through counsel, at least six times. Since the launch of the consent solicitation, the Velan Group has issued public communications at least thirteen times.

Not one of these communications — including the 162-page slide deck that Velan presented to Institutional Shareholder Services Inc. on October 18, 2019 and filed with the SEC on October 21, 2019 – makes even a passing reference to when the Velan Group learned of the Transaction before it was publicly announced, why the Velan Group was buying huge volumes of Progenics shares while aware of that non-public information, or why Velan declared its opposition to the Transaction before the terms had even come together. All shareholders deserve answers to these questions, especially as they contemplate whether to hand Velan control of your Company through the consent process. And assuming Velan’s five nominees did not previously know of Velan’s foreknowledge of the Transaction, those nominees should consider if they want to continue to associate with a group that operates in this manner.

Against the backdrop that the Velan Group and Mr. Venkataraman had non-public information, important questions need to be asked by all shareholders:

• How and when did the Velan Group come to learn of the potential Transaction between Progenics and Lantheus, including the identity of Lantheus’ financial advisor?
  
• What does it say about the Velan Group that it traded in Progenics shares when it knew of a possible M&A transaction (including the names of banks and specific bankers involved and, perhaps, enough detail to oppose the deal)?
  
• Did the five directors on the Velan Group’s slate have knowledge of these questionable actions when they signed on to work with Velan (thereby making them potentially culpable in these actions)?
  
• Did the Velan Group selectively share the non-public information it learned about the Transaction with other shareholders and/or its director nominees? Did any of these individuals purchase Progenics shares or take positions in Lantheus securities before the Transaction was announced based upon this non-public knowledge?
  
• On what basis did Velan form its opinion to oppose a potential M&A transaction before it was publicly announced and without the benefit of reading about its terms and background in the relevant SEC filings?
  
• How can Velan purport to represent the best interest of all Progenics shareholders when it declared privately its opposition to the Transaction before the Transaction and its relevant details were even publicly announced – and long before any proxy materials about the Transaction are to become publicly available?
  
• Why didn’t the Velan Group communicate any concerns about the Transaction to the Progenics’ Board and management, publicly or privately, in spite of ample opportunities to do so?
  
• What was the Velan Group’s true motive for launching the consent solicitation just two weeks before the long-negotiated Transaction’s public announcement?
  
• Why has Velan rushed to judgment and pushed forward with the consent solicitation before shareholders have had an opportunity to make fully informed voting decisions on the Transaction based on timely, complete and accurate information, which will be contained within the public filings related to the Transaction?
  
• If the Velan Group knew about the Transaction before its announcement, then to which “significantly changed circumstances” was counsel for the Velan Group referring to when it rejected the Company’s October 17 settlement offer that gave the Velan Group every single material term it had previously demanded in settlement negotiations?
  
• What do these actions say about Velan’s commitment to appropriate standards of corporate governance, transparency and integrity, and why, upon being given full control of your Company, would you expect this sort of behavior to not continue?
  
• Given this fact pattern, how can shareholders trust that the Velan Group’s proposed nominated directors to take control of the Progenics Board, and in effect your Company, without paying a premium for that control, will be appropriate stewards of your Company?

These facts require shareholders to ponder Velan’s actions vis-à-vis its opposition to the transaction and the preceding consent solicitation. Your Board and Company also believe these facts should be brought to the attention of the appropriate regulatory bodies and direct their attention to the matters raised.

What Else Are the Velan Group and Mr. Venkataraman Hiding from Shareholders?

The Velan Group is forcing you to vote on whether to remove and replace a majority of your Board before Progenics and Lantheus have made public complete information about the pending Transaction. Why does the Velan Group get to make decisions about the future of your Company, and potentially profit with non-public information while other shareholders do not?

Your Board has heard your call for change just three months ago at the 2019 annual meeting of stockholders. Since then, we have been dutifully implementing your governance and board composition feedback that was provided in the weeks following the 2019 annual meeting of stockholders. We have also continued carefully to position the Company for long-term value maximization. In addition to executing on our standalone plan, your Board has also given shareholders a superior path to value maximization through the Transaction that you will be asked to vote on a few months from now. Don’t allow Velan to prevent your voice from being heard in this important matter.

ALL our shareholders deserve the opportunity to vote on the negotiated Transaction without the distraction and disruption caused by Velan’s attempt to gain control of the Board for no premium. Sign the WHITE consent revocation card so that shareholders have a fair vote.

* * *

YOUR BOARD URGES YOU TO SIGN THE WHITE CONSENT REVOCATION CARD AND TO IGNORE ANY GREEN CONSENT CARDS SENT BY THE VELAN GROUP.

Thanks, as always, for your investment in Progenics.
