ObsEva Announces Strategic Reorganization to Consolidate Operations in Switzerland

Ad hoc announcement pursuant to Art. 53 LR of the SIX Swiss Exchange

GENEVA, Switzerland – February 24, 2023 – ObsEva SA (NASDAQ: OBSV; SIX: OBSN), a biopharmaceutical company developing and commercializing novel therapies for women’s health, today announced a strategic reorganization that will consolidate operations in Switzerland so as to preserve cash, focus resources towards the development of nolasiban, a novel, oral oxytocin receptor agonist to improve in vitro fertilization success rates, and manage its out-licensed programs. As part of the reorganization, the Company is downsizing its US-based Executive Management team and will similarly propose a reduced Board of Directors at the next Annual General Meeting. Additionally, ObsEva is retiring its convertible debt, is expecting to be delisted from Nasdaq, and intends to deregister from the US Securities and Exchange Commission (“SEC”), while maintaining its current listing on SIX Swiss Exchange.

“On behalf of the Board of Directors, I extend my sincere gratitude to Brian and the rest of the departing executive team for their leadership and contributions to ObsEva, and to all our departing employees for their efforts on behalf of the Company,” said Annette Clancy, Chairwoman of the Board of Directors. “The Board believes we are better positioned to deliver shareholder value following these difficult reorganization decisions. We look forward to strengthening the company by continuing the clinical development of nolasiban and with the future development of our out-licensed programs. We intend to initiate a Phase 1b trial for nolasiban in the second half of 2023 as we remain committed to our mandate of improving women’s health.”

Board of Directors and Management Changes

In connection with the reorganization, ObsEva’s Chairwoman, Annette Clancy, and Board members Brian O’Callaghan, Stephanie Brown, Anne VanLent, and Ed Mathers will not stand for re-election at the Company’s upcoming annual general meeting of shareholders. It is intended that ObsEva’s Founder, Dr. Ernest Loumaye, will be nominated as Board Chairman along with the nomination of Catarina Edfjäll as Board member.

Brian O’Callaghan stepped down as Chief Executive Officer effective February 23, 2023, with Will Brown, current Chief Financial Officer, appointed as Interim Chief Executive Officer, while also retaining the title of Chief Financial Officer. Additionally, Clive Bertram, Chief Commercial Officer, Brandi Howard, Chief Clinical Officer, and Luigi Marro, Chief Transformation Officer also departed the Company effective February 23, 2023. The Company has initiated a search for a permanent Chief Executive Officer to be based in Geneva, Switzerland.

The reorganization is expected to provide annual compensation savings of approximately $3.5 million.

Extinguishment of Convertible Debt

ObsEva has also negotiated the early retirement of $6.5 million in debt that represent amounts owed to certain funds and accounts managed by JGB Management, Inc. (“JGB”) pursuant to the Company’s Securities Purchase Agreement with JGB.

  CONFIDENTIAL

Under the terms of the early retirement, ObsEva and JGB agreed to apply $6.5 million previously held as collateral in a control account against the outstanding convertible notes on a pro rata basis, with JGB waiving a $1.1 million prepayment penalty in exchange for approximately $566 thousand in cash and $250,000 in the form of approximately 1.5 million common shares.

Delisting from the Nasdaq Capital Market

ObsEva has also notified The Nasdaq Stock Market LLC (“Nasdaq”) of the Company’s inability to comply with Listing Rule 5450(a)(1) because the bid price of ObsEva’s common shares was not at least $1.00 per share for ten consecutive business days since receiving the non-compliance notice on September 12, 2022. ObsEva had until March 13, 2023 to regain compliance with the minimum bid price requirement. Upon delisting of ObsEva’s common shares from the Nasdaq Capital Market, the Company intends to deregister with the SEC to suspend its obligation to file periodic reports under the Securities Exchange Act of 1934, as amended, including annual, quarterly and current reports on Form 10-K, Form 10-Q and Form 8-K, respectively, once certain conditions to deregistration are satisfied, including the Company having fewer than 300 record holders of its common shares. The Company expects the Nasdaq delisting and SEC deregistration to contribute to lower general and administrative costs in the future.

ObsEva intends to maintain its SIX Swiss Exchange listing and to continue to trade under the ticker symbol OBSN.
