Exhibit 99.1

Teligent Announces One-for-Ten Reverse Stock Split

Buena, N.J., MAY 26, 2020 (GLOBENEWSWIRE) -- Teligent, Inc. (NASDAQ: TLGT) (“Teligent” or the “Company”), a New Jersey-based specialty generic pharmaceutical company, announced today that as of 12:01 a.m., Eastern Time, on May 28, 2020 it will effect a one-for-ten reverse stock split of its outstanding common stock, which will be effective for trading purposes as of the commencement of trading on Thursday, May 28, 2020.

At a Special Meeting of Stockholders held on January 24, 2020 the reverse stock split was approved by the Company's stockholders to be effected at the Board’s discretion within the approved parameters and the specific ratio was subsequently approved by the Company's Board. The reverse stock split is intended to increase the per share trading price of the Company's common stock to satisfy the $1.00 minimum bid price requirement for continued listing on The NASDAQ Capital Market although no assurance can be given that continued listing will occur. Trading of the Company's common stock on The Nasdaq Capital Market will continue, on a post-split basis, with the opening of the markets on Thursday, May 28, 2020, under the existing trading symbol "TLGT" and under new CUSIP number 87960W 203.  The reverse stock split reduces the number of shares of the Company's common stock outstanding from approximately 53.9 million shares of common stock pre-reverse split to approximately 5.4 million shares of common stock post-reverse split. The number of outstanding options and warrants will also be also adjusted accordingly. The number of authorized shares of common stock and the par value per share will remain unchanged.

As a result of the reverse stock split, every 10 shares of the Company's pre-reverse split common stock will be combined and reclassified into one share of common stock. Voting rights and other rights of common stockholders will not be affected by the reverse stock split. No fractional shares of common stock will be issued as a result of the reverse stock split and any fractional shares that would otherwise be issuable as a result of the Reverse Stock Split will be rounded up to the nearest whole share.

After the effective time of the reverse stock split, stockholders with shares held in certificate form will receive a Letter of Transmittal and instructions from the Teligent’s transfer agent, American Stock Transfer & Trust LLC (AST). Stockholders that hold shares in book-entry form or hold their shares in brokerage accounts are not required to take any action and will see the impact of the reverse stock split reflected in their accounts. Beneficial holders of Teligent’s common stock are encouraged to contact their bank, broker, custodian or other nominee with questions regarding procedures for processing the reverse stock split.

Additional information about the reverse stock split can be found in the Company's Definitive Proxy Statement filed with the Securities and Exchange Commission (SEC) on December 23, 2019, and in the Company's Form 8-K filed with the SEC on January 27, 2020, copies of which are available at www.sec.gov or at the Company's website at www.teligent.com.
