Innoviva Reports Third Quarter 2021 Financial Results

· Royalties increased by 10% to $101.3 million in the third quarter of 2021, compared to the same quarter in 2020.

BURLINGAME, Calif., October 27, 2021 – Innoviva, Inc. (NASDAQ: INVA) (“Innoviva” and “the Company”) today reported financial results for the third quarter ended September 30, 2021.

· Gross royalty revenues of $101.3 million from Glaxo Group Limited (“GSK”) for the third quarter of 2021 included royalties of $54.1 million from global net sales of RELVAR^®/BREO^® ELLIPTA^®, royalties of $11.6 million from global net sales of ANORO^® ELLIPTA^® and royalties of $35.6 million from global net sales of TRELEGY^® ELLIPTA^®.¹

· Increase in fair values of strategic equity and long term investments of $33.6 million in the third quarter of 2021 was mainly due to higher net valuation as of September 30, 2021.

· Income from operations increased by 12% to $94.6 million, compared to the same quarter in 2020.

· Basic and diluted net income per share attributable to Innoviva stockholders increased 3.7 and 3.5 times to $1.04 and $0.90 from $0.28 and $0.26, respectively, compared to the same quarter in 2020,

· Net cash and cash equivalents totaled $135.1 million, and receivables from GSK totaled $101.3 million as of September 30, 2021.

Pavel Raifeld, Chief Executive Officer of Innoviva, Inc., stated, “Our royalty revenues grew 10% year over year, displaying strong positive momentum in a volatile environment.”

“RELVAR^®/BREO^® ELLIPTA^® global net sales decreased 15% compared to the third quarter of 2020 mainly because the significant favorable prior period adjustment in the U.S. in 2020 was not repeated. Non-U.S. sales increased 4% with strong growth in Japan and the EU despite generic competition and class-wide pressures. ANORO^® ELLIPTA^® global net sales decreased by 2% in the third quarter of 2021 due to pandemic-driven LABA/LAMA class weakness. U.S. net sales decreased with slower new patient growth. Non-U.S. ANORO^® ELLIPTA^® net sales increased 8% because of meaningful growth in select markets despite class challenges. TRELEGY^® ELLIPTA^®  global net sales increased 77% in the third quarter of 2021, driven by excellent U.S. growth for the triple therapy class and favorable prior period adjustment. Non-US TRELEGY^® ELLIPTA^® sales also grew as Trelegy continues to launch in new markets.”

Mr. Raifeld concluded, “We are pleased with the growth and resilience in our core royalty business. In addition, we are excited by strong progress across our asset portfolio, including recent pivotal clinical data read out at Entasis Therapeutics. Our financial performance remains robust, with basic net income per share exceeding $1 for the quarter, a nearly four-fold increase over the third quarter of 2020, supported by the recently completed equity repurchase, as we continue to focus on shareholder value creation through thoughtful capital deployment and operational excellence.”
