CITY, Calif., February 12, 2026 - Rezolute, Inc. (Nasdaq: RZLT) ("Rezolute" or the "Company"),

a late-stage rare disease company focused on treating hypoglycemia caused by all forms of hyperinsulinism (HI), today reported financial

results and provided a business update for the three months ended December 31, 2025.

Congenital Hyperinsulinism (HI)

Second Quarter Fiscal 2026 Financial Results

Cash, cash equivalents and investments in marketable

securities were $132.9 million as of December 31, 2025, compared with $167.9 million as of June 30, 2025.

Research and development (R&D) expenses were

$14.3 million for the second quarter of fiscal 2026, compared with $12.6 million for the same period a year ago. The increase from fiscal

year 2025 to fiscal year 2026 was primarily due to (i) increased expenditures in clinical trial activities and (ii) higher employee-related

expenses, which included one-time severance benefits related to the December 2025 reduction in force, partially offset by a decrease

in manufacturing costs for ersodetug.

General and administrative (G&A) expenses

were $9.9 million for the second quarter of fiscal 2026, compared with $4.5 million for the same period a year ago. The increase was primarily

attributable to increased professional fees and employee-related expenses, which included one-time severance benefits related to the December 2025

Net loss was $22.8 million for the second quarter

of fiscal 2026 compared with a net loss of $15.7 million for the same period a year ago.

Ersodetug is a fully human monoclonal antibody

that binds allosterically to the insulin receptor to decrease receptor over-activation by insulin and related substances (such as IGF-2)

in the setting of hyperinsulinism (HI), thereby improving hypoglycemia. Because ersodetug acts downstream from the pancreas, it has the

potential to be universally effective at treating hypoglycemia due to any congenital or acquired form of HI.
