WATERTOWN, Mass., August 5, 2020 - EyePoint Pharmaceuticals, Inc. (NASDAQ: EYPT), a pharmaceutical company committed to developing and commercializing innovative ophthalmic products, today announced financial results for the second quarter ended June 30, 2020 and highlighted recent corporate developments.

"We were encouraged by the re-opening of healthcare facilities in select regions of the U.S during the quarter-end as underlying customer demand from our distributors was strong in June for both YUTIQ and DEXYCU . We believe the distinct advantages of single-injection, long-lasting activity provides for fewer office visits and less contact with patient eyes and positions both products for expanded use during the COVID-19 pandemic and recovery," said Nancy Lurker, President and Chief Executive Officer of EyePoint Pharmaceuticals. "We are also very excited to announce our new U.S. commercial alliance with ImprimisRx for DEXYCU and believe that this collaboration will significantly enhance the DEXYCU opportunity by reaching new physicians and ambulatory surgery centers, while also pairing DEXYCU with Harrow's complementary ophthalmology drug offerings. In addition to increased physician reach, this agreement keeps our commercial cost structure at our previously announced reduced levels. As we continue to further build our commercial efforts and product education initiatives, we remain very focused on our balance sheet and continue to actively manage our spending burn rate as we look to extend our cash runway into 2021."

Ms. Lurker continued, "Our new Chief Strategic Scientific Officer, Dr. Jay Duker, will lead our development efforts for EYP-1901, a potential six-month sustained delivery anti-VEGF therapy using our bioerodible Durasert technology. The good laboratory practice (GLP) toxicology study for this program is progressing well and we expect data in the coming months to support filing of

an Investigational New Drug (IND) application in the fourth quarter. We are very excited to advance this program to potentially treat wet age-related macular degeneration (wet AMD), a significant market in need of innovative, long-lasting therapies."

Commercial Performance in Second Quarter 2020

Review of Second Quarter Results Ended June 30, 2020

For the three months ended June 30, 2020, total net revenue was $4.1 million compared to $7.2 million for the three months ended June 30, 2019. Net product revenue for the three months ended June 30, 2020 was $3.7 million, with $2.9 million for YUTIQ and $0.8 million for DEXYCU, compared to net product revenue for three months ended June 30, 2019 of $6.7 million generated by YUTIQ. Net product revenue represents product purchased by EyePoint's distributors whereas customer demand represents purchases of product by physician practices and ambulatory surgery centers from EyePoint's distributors.

Net revenue from royalties and collaborations for the three months ended June 30, 2020 totaled $416,000 compared to $505,000 in the corresponding quarter in 2019.

Operating expenses for the three months ended June 30, 2020 decreased to $15.3 million from $17.4 million in the prior year period, due primarily to decreased sales and marketing costs from our previously announced restructuring as well as lower research and development costs. Non-

operating expense, net, for the three months ended June 30, 2020 totaled $1.8 million of net interest expense. Net loss for the three months ended June 30, 2020 was $13.0 million, or $0.10 per share, compared to a net loss of $11.5 million, or $0.11 per share, for the prior year quarter.

Review of Six Months Results Ended June 30, 2020

For the six months ended June 30, 2020, total revenue was $11.6 million compared to $9.2 million for the six months ended June 30, 2019. Net product revenue for the six months ended June 30, 2020 was $8.4 million, compared to net product revenue for six months ended June 30, 2019 of $7.9 million.

Net revenue from royalties and collaborations for the six months ended June 30, 2020 totaled $3.2 million compared to $1.3 million in the corresponding quarter in 2019.

Operating expenses for the six months ended June 30, 2020 totaled $34.2 million from $34.0 million in the prior year period. This increase was primarily from higher cost of sales due to higher product sales as well as an increased royalty expense stemming from a $2 million upfront payment received during Q1-2020 for the licensing of DEXYCU in China.

Non-operating expense, net, for the six months ended June 30, 2020 totaled $3.5 million. Net loss for the six months ended June 30, 2020 was $26.1 million, or $0.22 per share, compared to a net loss of $30.7 million, or $0.30 per share, for the prior year period.

Cash and cash equivalents at June 30, 2020 totaled $22.8 million compared to $22.2 million at December 31, 2019.

We expect that the Company's cash and cash equivalents combined with projected cash inflows from anticipated YUTIQ and DEXYCU product sales and other expected financing activities can fund the Company's operating plan into 2021 under current assumptions for the duration of the COVID-19-related closures across the U.S.

The Company continues to assess additional cash conservation and generation measures to support its operations through the COVID-19 pandemic.
