purport to contain all the information that may be necessary or desirable to fully and accurately evaluate an investment in the Company; (c) is not to be considered as a recommendation by the Company that any person make an investment in the

historical fact, certain information contained herein constitutes forward-looking statements which include but are not limited to statements regarding: stockholder approval of the conversion rights of the Series A Preferred Stock; the expected

inflammatory bowel disease therapies; other activities, events or developments that the Company expects or anticipates will or may occur in the future; the Company’s business strategy objectives and goals; and management’s assessment of
future plans and operations which are based on current internal expectations, estimates, projections, assumptions and beliefs, which may prove to be incorrect. Forward-looking statements can often be identified by the use of words such as
“may”, “will”, “could”, “would”, “anticipate”, ‘believe”, expect”, “intend”, “potential”, “estimate”, “scheduled”,
“plans”, “planned”, “forecasts”, “goals” and similar expressions or the negatives thereof. Forward-looking statements are neither historical facts nor assurances of future performance. Forward-looking

Aeglea-Spyre Transaction highlights Structure: The acquisition of Spyre
was structured as a stock-for-stock transaction whereby all of Spyre’s outstanding equity interests were exchanged for a combination of shares of Aeglea common stock and a newly created non-voting Series A convertible preferred stock.
Financing: Concurrent with the acquisition of Spyre, Aeglea closed a $210 million private placement with a group of institutional accredited investors led by Fairmount Funds and joined by a robust syndicate of dedicated biotechnology investors as
well as additional undisclosed institutional investors. Primary use of proceeds: The proceeds from the private placement are expected to be primarily used to advance the Spyre pipeline and deliver the following anticipated milestones: two INDs for
SPY001 and SPY002 in 2024, HV PK/PD data for SPY001 in 2H2024, and HV PK/PD data for SPY002 in 1H2025. Proceeds are expected to provide cash runway into 2026. 37
Capitalization * As of 6/20/2023 • Shares of common stock and
preferred stock Shares of common stock outstanding 2.6 million were issued to Spyre Therapeutics Inc. security holders in exchange for all of Spyre’s outstanding Pre-funded warrants 1.2 million equity interests. Merger consideration •
Shares of preferred stock were issued to Spyre Therapeutics Inc. stockholders and to investors in Shares of common 0.5 million the $210 million private placement. Shares of preferred 0.4 million • Each share of preferred stock will
automatically Preferred conversion ratio 1:40 convert into 40 shares of common stock upon Total pre-financing common equivalent 18.9 million stockholder approval, subject to certain beneficial ownership restrictions set by each holder. Concurrent
financing • Please refer to the company’s SEC filings for Shares of preferred 0.7 million additional information. Common equivalent 28.9 million Total capitalization (Common) 47.7 million *Note: All figures have been retroactively
