Exhibit 99.1 New Horizons in Bladder Cancer: UGN-102 Duration of Response Results from the ENVISION Study NASDAQ: URGN June 13, 2024 1

Forward-Looking St at ement s This investor presentation contains forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995, including, without limitation: the potential for UroGen to transform bladder cancer treatment; the potential of JELMYTO® to change the treatment paradigm in LG-UTUC; the potential of UGN-102 to transform the treatment paradigm in LG-IR-NMIBC; the potential of UGN-301 to expand to Immuno-Oncology for HG-NMIBC; the estimated patient population in bladder cancer and estimated addressable patient population for UGN-102 in LG-IR-NMIBC and UGN-301 in HG-NMIBC; the estimated total addressable market opportunity for UGN-102 in LG-IR-NMIBC; the potential for UGN-102 to become the first FDA approved medicine for LG-IR-NMIBC; the opportunity and potential benefits of UGN-102 for LG-IR-NMIBC and potential advantages over TURBT; the potential NDA completion and review timeline for UGN-102, including the expected completion of the NDA submission to the FDA and the FDA’s potential acceptance thereof and the FDA’s potential approval timing; and the potential of UroGen’s proprietary RTGel® technology platform to improve therapeutic profiles of existing drugs. These statements are subject to a number of risks, uncertainties and assumptions, including, but not limited to: ENVISION duration of response data may not be sufficient to support an NDA submission for UGN-102; even if an NDA for UGN-102 is accepted by the FDA, there is no guarantee that such NDA will be sufficient to support approval of UGN-102 on the timeframe expected, or at all; the timing and success of clinical trials and potential safety or other complications encountered therein; results from prior or ongoing clinical trials may not be indicative of results that may be observed in the future; unforeseen delays that may impact the timing of progressing clinical trials and reporting data; the ability to obtain regulatory approval within the timeframe expected, or at all; the ability to maintain regulatory approval; complications associated with product development and commercialization activities; the labeling and packaging for any approved product; competition in UroGen's industry; the scope, progress and expansion of developing and commercializing UroGen’s product and product candidates; the size and growth of the market(s) therefor and the rate and degree of market acceptance thereof vis-à-vis alternative therapies; RTGel technology may not perform as expected and UroGen may not successfully develop and receive regulatory approval of any product candidate beyond JELMYTO that incorporates its RTGel technology; and UroGen’s ability to attract or retain key management, members of the board of directors and personnel. In light of these risks and uncertainties, and other risks and uncertainties that are described in the Risk Factors section of UroGen’s Form 10-Q for the quarter ended March 31, 2024, filed with the Securities and Exchange Commission (SEC) on May 13, 2024, and other filings that UroGen makes with the SEC from time to time (which are available at http://www.sec.gov), the events and circumstances discussed in such forward- looking statements may not occur, and UroGen’s actual results could differ materially and adversely from those anticipated or implied thereby. Any forward-looking statements speak only as of the date of this presentation and are based on information available to UroGen as of the date of this presentation.

ENVISION PATIENT PERCEPTIONS OF UGN-102 AND TURBT: IMPACT ON DAILY ACTIVITIES 33

ENVISION Int erviews • Patients with NMIBC commonly ask urologists how their daily activities/responsibilities will be affected by treatment(s) • In ENVISION, we interviewed patients about the impact on their daily activities with UGN-102 and their recollection of standard of care (transurethral resection of bladder tumor [TURBT]) • N=29 U.S. patients (out of 39 eligible [74%]) 34 34 Stover and Smith, under review

Methods • Gold standard: content analysis - Data are patient quotes • Semi-structured interview guides at enrollment and 3 months • Transcripts coded by 3 experienced coders with detailed codebooks (software: Dedoose) • Emerging themes and discrepancies were captured and reconciled through consensus 35 35 Stover and Smith, under review

Recovery Time UGN-102 TURBT “Well, first off, they're [TURBTs] “Yes. I think it took me a gettin' more and more painful, longer time to recover from and it's taken longer and the bladder resection than the longer to recover from them. gel. [For TURBT], maybe at two It's just a little bit of—every time weeks I felt better and things they do it [TURBT], it's just little like that, and I start to exercise, bit more incontinence. It's but I do believe that I was not at gotten much worse with each my 100 percent until many procedure.” (17) weeks later.” (27) 37 Stover and Smith, under review

No Impact on Daily Act ivit ies UGN-102 TURBT “With the gel, the daily activity was a big difference, and I didn’t worry at [TURBT not discussed] all. Basically, I lived my normal life except the one day [instillation], which was well worth it.” (34) “They [UGN-102] didn’t have any impact on me. I went in, and I went back to my normal activity…I had no problems at all.” (37) 38 Stover and Smith, under review

Impact on W ork TURBT UGN-102 “It's [incontinence] mostly a big “The TURBT, I was basically missing embarrassment and an absolute for seven, eight days, I could do no pain in the ass at work…some days work. Here [with UGN-102], really, are much worse than others and work has continued, I have not depending on what I'm doin'—but had an impact. Again, postponing sometimes my pants get wet, and travel, meetings, things like that, I have to go out to the car, get my but I was present, mostly, I was clothes, change, and they're present.

I do not “It was very itchy, all my bladder and everything. The second time, I look forward to spending the rest knew what it was. Knowing what it of my life attached to a was, the scary part went away. I catheter. That’s a no-no for me.” wasn't worried anymore. It was just (08) toughing it out that one or two days.” (29) 40 Stover and Smith, under review

Bleeding UGN-102 TURBT “That [TURBT] was a lot of bleeding.” (45) “At least two occasions [for “They removed five polyps at that TURBT], one of which there was time…Then I bled for two weeks. fair amounts of bleeding.” (03) Finally shut off.

From the patient perspective, UGN-102 meets an unmet need in care delivery for a non-surgical treatment alternative for NMIBC 43 43
