is developing the Elk Creek Project, located in southeast Nebraska.

The Elk Creek Project is a development-stage property that

has disclosed niobium, scandium, and titanium reserves and resources and disclosed rare earth mineral resources.

The Company is

continuing technical and economic studies around the rare earths contained in the Elk Creek Project’s mineral resources

in order to determine whether extraction of rare earth elements can be reasonably justified and economically viable after taking

into account all relevant factors.

Niobium has developing applications in the formulation of solid-state lithium-ion batteries,

which may reduce charging times and increase battery safety.

Niobium is used to produce various superalloys that are extensively

used in high performance aircraft and jet turbines.

It also is used in High-Strength, Low-Alloy steel, a stronger steel used in

automobiles, bridges, structural systems, buildings, pipelines, and other applications that generally increases strength and/or

reduces weight, which can result in environmental benefits, including reduced fuel consumption and material usage and fewer air

Scandium can be combined with aluminum to make high-performance alloys with increased strength and improved corrosion

Scandium also is a critical component of advanced solid oxide fuel cells, an environmentally preferred technology

for high-reliability, distributed electricity generation.

Titanium is a component of various superalloys and other applications

that are used for aerospace applications, weapons systems, protective armor, medical implants, and many others.

It also is used

in pigments for paper, paint, and plastics.

Rare earths are critical to electrification and decarbonization initiatives and can

be used to manufacture the strongest permanent magnets commercially available.

primary business strategy is to advance our Elk Creek Project to commercial production.

We are focused on carrying out our near-term

planned work programs associated with securing the project financing package necessary to complete mine development and construction

of the Elk Creek Project.

The Company received net proceeds from the October 2025 Offering, after deducting placement agent fees and other offering expenses payable by the Company, of approximately $139.1 million.

The Company intends to use the net proceeds from the October 2025 Offering for working capital and general corporate purposes, including to advance its efforts to launch construction of the Elk Creek Project and move it to commercial operation.

On November 21, 2025, the Company adopted a limited-duration shareholder rights plan (the “Rights Plan”).

One right (a “Right”) was issued for each Common Share outstanding as of December 4, 2025, and a Right automatically attaches to each subsequently issued Common Share until the expiration of the Rights Plan.

The Rights generally become exercisable only if a person or group acquires or announces the current intention of commencing a take-over bid to acquire beneficial ownership of 20% or more of the Company’s outstanding Common Shares other than through a permitted bid made in compliance with applicable Canadian take-over bid rules.

If the Rights become exercisable, each holder of a Right, other than the acquiring person, would be entitled to purchase additional Common Shares at a discount to the then-current market price.

The Board adopted the Rights Plan to help ensure that all shareholders of the Company are treated equally and fairly in the event of any unsolicited take-over bid or other attempt to acquire control of the Company (including by way of a "creeping take-over bid").

In respect of such transactions, the Rights Plan is intended to, among other things:

• encourage potential bidders to treat the Company's shareholders fairly and equally and preserve control premiums and value for shareholders;

• provide the Board and shareholders adequate time to appropriately respond on an informed basis.

The Rights Plan was not adopted in response to any specific take-over proposal.

The Plan expires on May 21, 2026, or earlier as provided by the terms of the agreement governing the Rights Plan.

On December 4, 2025, the Company, through its newly-formed subsidiary, NioCorp Advanced Metals and Alloys, LLC, completed the acquisition of the manufacturing assets and intellectual property of FEA Materials LLC for $8.4 million in cash.

The acquired assets include equipment and proprietary technology used to produce Al-Sc master alloy through an innovative process that converts scandium oxide directly into Al-Sc master alloy, eliminating the need to first manufacture scandium metal.

This technology is expected to meaningfully reduce processing complexity and cost relative to traditional methods.

The acquisition strengthens the Company’s downstream commercialization strategy by potentially enabling the future production of Al-Sc master alloy in the United States, subject to completion and financing of the Elk Creek Project.

Elk Creek Project Update

On August 1, 2025, Elk Creek Resources Corp.

(“ECRC”), an indirect, majority-owned subsidiary of the Company, closed on its option to purchase three parcels of land in Johnson County, Nebraska, pursuant to the terms of an Option to Purchase dated December 4, 2009, as amended (the “2009 Option Agreement”), and an Option to Purchase dated December 4, 2014, as amended (together with the 2009 Option Agreement, the “August Option Agreements”).

Pursuant to the terms of the August Option Agreements, ECRC acquired all surface rights with respect to an approximately 80-acre parcel and both surface and associated mineral rights with respect two additional parcels totaling approximately 1.66 acres.

The aggregate purchase price was approximately $2.7 million, including indirect costs of $35.

On September 8, 2025, the Company announced the successful completion of its previously announced drilling program at the Elk Creek Project (the “2025 Drilling Program”).

The 2025 Drilling Program was divided into two phases.

Phase I of the 2025

Drilling Program comprised 11 HQ diamond drill holes totaling approximately 7,339 meters and Phase II of the 2025 Drilling Program

comprised four HQ diamond drill holes totaling approximately 2,235 meters.

Two additional geomechanical drill holes totaling approximately

1,950 meters were also completed as part of an accelerated effort to support the underground mine design related to access ramp

Phase I of the 2025 Drilling Program comprised 11 HQ diamond drill holes totaling approximately 7,339 meters and Phase II of the 2025 Drilling Program comprised four HQ diamond drill holes totaling approximately 2,235 meters.

Two additional geomechanical drill holes totaling approximately 1,950 meters were also completed as part of an accelerated effort to support the underground mine design related to access ramp development.

Assays of the drill holes completed during the 2025 Drilling Program are underway at external laboratories.

2025 Drilling Program and associated technical work is designed to support the conversion of a portion of the Elk Creek Project's

Indicated Mineral Resources into Measured Mineral Resources and the subsequent conversion of a portion of its Probable Mineral

Reserves into Proven Mineral Reserves.

The 2025 Drilling Program was designed to help meet Mineral Resource and Mineral Reserve

classification requirements associated with the ongoing review of the Company's application for up to $800 million in potential

debt financing by EXIM, as further discussed under “—Liquidity and Capital Resources.”

September 30, 2025, ECRC closed on its options to purchase two parcels of land in Johnson County, Nebraska, which include:

a portion of the property known as Woltemath002, consisting of approximately 105.77 acres of land (the “Woltemath002 Property”),

pursuant to the terms of the 2009 Option Agreement and (ii) the property known as Woltemath003J, consisting of approximately 220

acres of land (the “Woltemath003J Property” and, together with the Woltemath002 Property, the “ September Properties”),

pursuant to the terms of the Amended and Restated Option to Purchase, dated January 4, 2017, as amended, between Victor and Juanita

Woltemath (together with Roger and Nancy Woltemath, the “Owners”) and ECRC (the “2017 Option Agreement”

and, together with the 2009 Option Agreement, the “September Option Agreements”).

Pursuant to the terms of the September

Option Agreements, the Owners sold, transferred, conveyed and assigned to ECRC all of their respective rights, privileges, title

and interest in and to the surface rights and associated mineral rights, which consisted of approximately 325.77 acres of the

The 2025 Drilling Program and associated technical work was designed to support the conversion of a portion of the Elk Creek Project's Indicated Mineral Resources into Measured Mineral Resources and the subsequent conversion of a portion of its Probable Mineral Reserves into Proven Mineral Reserves and to help meet Mineral Resource and Mineral Reserve classification requirements associated with the ongoing review of the Company's application for up to $800 million in potential debt financing by EXIM, as further discussed under “—Liquidity and Capital Resources.”

On September 30, 2025, ECRC closed on its options to purchase two additional parcels of land in Johnson County, Nebraska (the “September Properties”), pursuant to the terms of the 2009 Option Agreement and an Amended and Restated Option to Purchase dated January 4, 2017, as amended (together with the 2009 Option Agreement, the “September Option Agreements”).

The September Properties consisted of approximately 325.77 acres of land.

Pursuant to the terms of the September Option Agreements, ECRC acquired all surface rights and associated mineral rights relating to the September Properties.

The aggregate purchase price was approximately $11.3 million, including indirect costs of $29.

This acquisition

provides NioCorp with ownership of all land that hosts the Elk Creek Project’s Mineral Resource and Mineral Reserve and

all acreage necessary to commence construction once project financing is obtained.

On November 7, 2025, ECRC completed the acquisition of a 40-acre parcel of land and associated mineral rights (the “November

Property”) located within the one-square-mile section that comprises the Elk Creek Project area.

The acquisition was

completed in exchange for (i) the transfer of surface rights to a separate 40-acre tract constituting a portion of the September

Properties, which lies outside the Elk Creek Project section, (ii) cash consideration of $500, and (iii) the grant of a 2%

net smelter return royalty on the November Property.

As a result of this transaction, the Company now holds full ownership

of all surface rights within the one-square-mile section in which it plans to construct both the underground critical

minerals mine and integrated surface processing facility associated with the Elk Creek Project.

Company continues to execute a work plan to further advance the development of the Elk Creek Project.

In addition to the expected

updates to Mineral Resources and Mineral Reserves, noted above, the Company expects to finalize engineering and costing of its

new and more efficient production process which incorporates the potential addition of light and heavy magnetic rare earth oxides,

the planned production of titanium in the form of titanium tetrachloride, and the potential to produce both ferroniobium and niobium

oxide as commercial products.

In addition, the Company is advancing engineering to potentially modify the design of the mine to

incorporate a twin ramp for access along with a Railveyor system for material movement instead of utilizing vertical mining shafts.

The updated mine design is expected to also incorporate updated costing.

This work is expected to be summarized in an updated

feasibility study for the Elk Creek Project.

addition to the work plans noted above, as funds become available through the Company’s fundraising efforts, the Company

expects to undertake the following activities to further advance the Elk Creek Project and the Company is assessing and prioritizing

the timing of these efforts:

evaluation of the potential to produce rare earth products and sell such products under offtake agreements;

and completion of offtake agreements for the remaining uncommitted production of niobium, scandium, and titanium from the

Elk Creek Project, including the potential sale of titanium as titanium tetrachloride, as well as potential rare earth element

and completion of engineering, procurement, and construction agreements;

of personnel to manage the Company’s responsibilities for construction and operations;

of the final detailed engineering for the underground portion of the Elk Creek Project;

and completion of the final detailed engineering for surface project facilities;

of natural gas and electrical infrastructure to serve the Elk Creek Project site;

of water supply agreements and related infrastructure to deliver fresh water to the Elk Creek Project site;

of mine groundwater investigation and control activities;

of long-lead equipment procurement activities;

of the Company’s efforts to secure additional federal, state, and local operating permits;

of the characterization and testing of waste materials to support tailings impoundment and paste backfill plant designs;

engineering and costing of road improvements near the junction of Nebraska state highways 50 and 62, which are intended to

facilitate access to the Elk Creek Project site and manage increased traffic in the project vicinity.

and Operating Results

Company has no revenues from mining operations.

Operating expenses incurred primarily related to costs incurred for the advancement

of the Elk Creek Project and the activities necessary to support corporate and shareholder duties and are detailed in the following

For the Three Months Ended

September 30,

On November 7, 2025, ECRC completed the acquisition of a 40-acre parcel of land and associated mineral rights (the “November Property”) located within the one-square-mile section that comprises the Elk Creek Project area.

The acquisition was completed in exchange for (i) the transfer of surface rights to a separate 40-acre tract constituting a portion of the September Properties, which lies outside the Elk Creek Project section, (ii) cash consideration of $500, and (iii) the grant of a 2% net smelter return royalty on the November Property.

As a result of this transaction, the Company now holds full ownership of all surface rights within the one-square-mile section in which it plans to construct both the underground critical minerals mine and integrated surface processing facility associated with the Elk Creek Project.

On December 22, 2025, the Board approved the Company’s Mine Portal Project (the “Portal Project”), at the Elk Creek Project site.

The Portal Project will establish the main entrances to the Elk Creek Project underground mine, which will serve as the primary access points for personnel, equipment, and materials for the Company’s planned underground mining operations.

The Board-approved scope also includes excavating to bedrock, drilling and blasting to establish the twin mine ramps, on-site access

road construction, as well as on-site supporting infrastructure.

Work with respect to the Portal Project is expected to begin in the first quarter of calendar year 2026.

The current estimated capital cost for the project is approximately $44.6 million;

however, there can be no assurance that the actual capital cost of the Portal Project will not be materially greater than such estimate.

Other Activities

The Company continues to execute a work plan to further advance the development of the Elk Creek Project.

In addition to the expected updates to Mineral Resources and Mineral Reserves, noted above, the Company expects to finalize engineering and costing of its new and more efficient production process which incorporates the potential addition of magnetic rare earth products and the planned production of titanium in the form of titanium tetrachloride.

period ended September 30, 2025 compared to the three-month period ended September 30, 2024

items affecting operating expenses are noted below:

Employee-related

expenditures increased for the three-month period in 2025 as compared to 2024 primarily due to the timing of options issued

to employees in 2025.

fees increased for the three-month period in 2025 as compared to 2024, primarily due to higher costs incurred in 2025 related

to the timing of legal services associated with the preparation of the Company’s SEC registration statements filed in October

expenditures increased for the three-month period in 2025 as compared to 2024, primarily due to expenditures associated with

the 2025 Drilling Program.

operating expenses include costs related to investor relations, general office expenditures, shareholder services and proxy

expenditures, board-related expenditures, and other miscellaneous costs.

These costs increased for the three-month period in 2025

as compared to 2024 primarily due to the timing of fully vested options to purchase

Common Shares (“Options”) issued

to board members and advisors in 2025 and increases in investor-facing services and stipend payments provided to board members.

significant items impacting the change in the Company’s net loss and net loss per share are noted below :

in fair value of Earnout Shares liability represents the changes in fair value related to the shares of Class B common stock

of ECRC, the rights of the holders of which to exchange such shares into Common Shares are subject to certain vesting conditions

(such shares of ECRC Class B common stock, the “Earnout Shares”).

The 2025 expense represents the impact of an increase

in the Company’s Common Share price on the financial modeling used to determine the period end fair values, whereas the

2024 gain represents the impact of a lower share price on the financial modeling results.

in fair value of warrant liabilities represents the changes in fair value of Warrants that are carried as liabilities in the

condensed consolidated balance sheet.

Expense for the three-month period ending September 30, 2025, reflects the impact of an

increase in the Company’s Common Share price on the Black-Scholes modeling results for our outstanding Warrant liabilities,

whereas the 2024 gain primarily represents the impact of a lower share price on the modeling at period end.

income represents earnings from the investment of excess cash balances in a commercial money market account.

for the three-month period in 2025 as compared to 2024 is due to an increase in our cash balance resulting from our successful

financing efforts during calendar year 2025.

attributable to noncontrolling interest represents the portion of net loss in ECRC not owned by the Company.

in loss for the three-month period in 2025 as compared to 2024 is related to the increased exploration expenditures, as noted

above, incurred by ECRC.

net loss and adjusted net loss per share both increased for the three-month period in 2025, as compared to 2024, primarily due

to the increase in exploration expenditures, as noted above, incurred by ECRC.

and Capital Resources

have no revenue generating operations from which we can internally generate funds.

To date, our ongoing operations have been financed

by the sale of our equity securities by way of public and private offerings, convertible securities issuances, the exercise of

Options and Warrants, and related party loans.

With respect to currently outstanding Options and Warrants, we believe that exercise

of these instruments, and cash proceeds from such exercises, will not occur unless and until the market price for our Common Shares

equals or exceeds the related exercise price of each instrument.

discussed above under “— Recent Corporate Events ”, the Company closed four equity offering transactions

between July 18, 2025 and October 15, 2025.

The combined net proceeds from these offerings were approximately $194.4 million,

after deducting placement agency fees and other offering expenses payable by the Company.

In addition, during the three-month

period ended September 30, 2025, the Company issued an aggregate of 10,975,634 Common Shares through the exercise of Warrants

and Options by their holders, for which the Company received proceeds totaling approximately $15.2 million.

The Company expects

to use these net proceeds for working capital and general corporate purposes, including to advance efforts to launch construction

of the Elk Creek Project and move it to commercial operation.

of September 30, 2025, the Company had cash of $162.8 million and working capital of $159.6 million, compared to cash of $25.6

million and working capital of $24.8 million on June 30, 2025.

expect that the Company will operate at a loss for the foreseeable future.

The Company’s current planned cash outflows are

approximately $40.0 million to $50.0 million for the next twelve months.

Our planned cash outflows over the next twelve months

are expected to consist of expenditures relating to limited, incremental activities to advance certain aspects of the Elk Creek

Project by NioCorp’s majority owned subsidiary, ECRC, corporate overhead costs, and estimated costs related to securing

financing necessary for advancement of the Elk Creek Project.

These planned expenditures include expenditures relating to the

anticipated completion of an updated resource and reserve estimate

and associated mine plan and an updated capital cost estimate

in connection with the EXIM application process, ongoing engineering and metallurgical test work, environmental and permitting

activities, community and stakeholder engagement programs, corporate and administrative overhead, and advisory costs related to

securing project financing.

Company will need to secure additional capital to finance construction and achieve commercial production to support its

long-term business objectives.

Until sufficient funding for construction is secured, the Company expects to limit activities

to modest, value-preserving work and project readiness efforts.

The Company also intends to evaluate strategies and potential

investment opportunities that could reduce overall project costs, capital requirements, or execution risk.

planned corporate overhead costs over the next twelve months are approximately $11.0 million, including Elk Creek property lease

commitments, which are $65,000 through June 30, 2026, and the settlement of outstanding accounts payable as of September 30, 2025.

estimated financing costs associated with the Elk Creek Project over the next twelve months include, but are not limited to, costs

relating to the EXIM application process, the scope of which remains under discussion with EXIM.

On June 6, 2023, the Company

announced that it had submitted an application to EXIM for up to $800 million in debt financing (the “EXIM Financing”)

to fund the project costs for the Elk Creek Project, under EXIM’s “Make More in America” initiative.

Financing is subject to, among other matters, the satisfactory completion of due diligence, the negotiation and settlement of

final terms, and the negotiation of definitive documentation.

The Company was informed that its application received approval

by the first of three reviews by the EXIM Transaction Review Committee (the “TRC”) on October 2, 2023.

In April 2024,

EXIM provided the Company with a preliminary, non-binding indicative term sheet as part of a Preliminary Project Letter (the “PPL”),

which also conveyed EXIM’s initial due diligence findings on the Company’s application for the EXIM Financing.

PPL identified additional project activities to be undertaken by the Company as part of EXIM’s due diligence process.

included, among other things, an updated mine plan and updated Elk Creek Project capital costs on a final or close-to-final basis

reflecting updated process flows.

The 2025 Drilling Program, which started in April 2025, was designed to help meet mineral resource

and mineral reserve classification requirements necessary to complete certain of the additional project activities identified

In addition, as previously disclosed, the Company took an additional step in the process by executing a professional

services agreement with SLR Consulting to conduct an independent environmental and social review as part of EXIM’s ongoing

project due diligence.

Company continues to meet with EXIM, provide responses to requests for additional information from EXIM and to the consultants

that are conducting due diligence on the Company’s application on behalf of EXIM and take steps to complete the additional

project activities identified by the PPL.

There can be no assurance as to what further project activities or matters EXIM may

request in connection with the application process.

We are currently unable to estimate how long the application process may take,

and there can be no assurances that we will be able to successfully negotiate a final commitment of debt financing from EXIM.

expect our cash balance as of September 30, 2025, as well as the net proceeds from the October 2025 Offering, the proceeds from

Warrant and Option exercises that occurred since September 30, 2025, and the reimbursement payments pursuant to the DoD Agreement,

to be sufficient to fund our planned expenditures for the next twelve months.

However, additional work is required in order to

advance the Elk Creek Project to construction, requiring additional financing.

The technical report summary for the Elk Creek

Project prepared in accordance with subpart 1300 of Regulation S-K (“S-K 1300”) and filed as Exhibit 96.1 to the Company’s

Annual Report on Form 10-K for the fiscal year ended June 30, 2025, includes an estimated total upfront capital expenditure for

the Elk Creek Project of approximately $1,141.0 million.

The actual amount of capital expenditure required to successfully achieve

commercial production at the Elk Creek Project is subject to, among other factors, the timing and actual cost of further exploration,

preparing feasibility studies, permitting, engineering and the construction of infrastructure, mining and processing facilities.

In addition, to the extent that EXIM requests further project activities to be undertaken in connection with the diligence process,

the Company would require additional funding to complete such activities.

As noted above, the Company’s ability to continue

operations, fund our current work plan, and construct and operate the Elk Creek Project is dependent on management’s ability

to secure additional financing.

When available, the Yorkville Equity Facility Financing Agreement provides an opportunity

for opportunistic share sales to help fund our current work plan.

However, the Yorkville Equity Facility Financing Agreement will

expire by its terms on April 1, 2026.

for the potential funding from advances under the Yorkville Equity Facility Financing Agreement, as discussed above, and the potential

exercise of Options and Warrants, we currently have no further funding commitments or arrangements for additional financing at

Management currently anticipates that it will fund the upfront capital expenditure amount for the Elk Creek Project

through a combination of debt and equity financing, with approximately two-thirds of such amount being funded from the net proceeds

of debt financing, including the amount of debt that would be represented by the EXIM Financing, if any.

Management is actively

pursuing additional sources of debt and equity financing to meet its long-term funding requirements, and while it has been successful

in doing so in the past, there is no assurance that we will be able to obtain any such additional financing on acceptable terms,

Pursuant to the Exchange Agreement, dated as of March 17, 2023 (as amended, supplemented or otherwise modified, the

“Exchange Agreement”), by and among NioCorp, ECRC and GX Sponsor II LLC, NioCorp is restricted from issuing equity

or equity-linked securities (other than Common Shares) or any preferred equity or non-voting equity if such issuance would adversely

impact the rights of the holders of the shares of Class B common stock of ECRC, without the consent of the holders of a majority

of the shares of Class B common stock of ECRC.

The various placement agency agreements entered into with Maxim in connection with

the equity offerings described above under “— Recent Corporate Events ,” including the October 2025 Placement

Agency Agreement, also contain certain covenants that, among other things, limit NioCorp’s ability to enter into any variable

rate transaction on or before November 28, 2025, including issuances of equity or debt securities that are convertible into Common

Shares at variable rates and any equity line of credit, at-the-market offering agreement, or other continuous offering of Common

Shares, other than with Maxim, subject to certain exceptions.

Notwithstanding the restrictions set forth in the Exchange Agreement,

as well as the various placement agency agreements, there is significant uncertainty that we would be able to secure any additional

financing in the current equity or debt markets.

The quantity of funds to be raised and the terms of any proposed equity or debt

financing that may be undertaken will be negotiated by management as opportunities to raise funds arise.

Management may pursue

funding sources of both debt and equity financing, including but not limited to the issuance of equity securities in the form

of Common Shares, Warrants, subscription receipts, or any combination thereof in units of the Company pursuant to private placements

to accredited investors or pursuant to public offerings in the form of underwritten/brokered offerings, registered direct offerings,

or other forms of equity financing and public or private issuances of debt securities, including secured and unsecured convertible

debt instruments, or secured debt project financing.

Management does not currently know the terms pursuant to which such financings

may be completed in the future, but any such financings will be negotiated at arm’s-length.

Future financings involving

the issuance of equity securities or derivatives thereof will likely be completed at a discount to the then-current market price

of the Company’s securities and will likely be dilutive to current shareholders.

In addition, we could raise funds through

the sale of interests in our mineral properties, although current market conditions and other recent worldwide events have substantially

reduced the number of potential buyers/acquirers of any such interests.

However, we cannot provide any assurances that we will

be able to be successful in raising such funds.

As defined under S-K 1300, we are a development stage issuer and we have

incurred losses since our inception.

Three-month period ended December 31, 2025 compared to the three-month period ended December 31, 2024

Significant items affecting operating expenses are noted below:

Employee-related expenditures increased for the three-month period in 2025 as compared to 2024 primarily due to the timing of grants of options to purchase Common Shares ("Options") issued to employees in 2025 and the hiring of additional corporate staffing.

Professional fees increased for the three-month period in 2025 as compared to 2024 primarily due to higher legal costs incurred in connection with the preparation of the Company’s SEC registration statements filed in October 2025.

Exploration expenditures increased for the three-month period in 2025 as compared to 2024, primarily due to costs associated with the Company's current efforts to update the Elk Creek Project feasibility study.

Other operating expenses include costs related to investor relations, general office expenses, shareholder services and proxy related activities, board-related expenditures, and other miscellaneous items.

These costs increased for the three-month period in 2025 as compared to 2024 primarily due the timing of Option grants issued to board members and advisors, as well as higher investor-facing service costs.

Other significant items impacting the change in the Company’s net loss and net loss per share are noted below :

Change in fair value of earnout shares liability represents the impact of changes in fair value related to shares of Class B common stock of ECRC, the rights of the holders of which to exchange such shares into Common Shares are subject to certain vesting conditions (such shares of ECRC Class B common stock, the "Earnout Shares").

The decline in fair value

for the three-month period in 2025 as compared to 2024 primarily reflect the decrease in the Company’s Common Share price in the financial modeling used to determine the period end fair value.

Change in fair value of warrant liabilities represents the impact of changes in fair value of Warrants recorded as liabilities in the condensed consolidated balance sheet.

The declines in fair value for the three-month period in 2025 as compared to 2024 primarily reflect decreases in the Company’s Common Share price used in the Black-Scholes valuation of outstanding Warrant liabilities.

In addition, the 2025 decline was partially offset by additional fair value expense recognized in connection with Warrants exercised during the period.

Interest income represents earnings from the investment of excess cash balances in a commercial money market account.

The increase for the three-month period in 2025 as compared to 2024 is attributable to our higher cash balance resulting from our successful financing efforts during calendar year 2025.

Loss attributable to noncontrolling interest represents the portion of net loss in ECRC not owned by the Company.

The increase in loss for the three-month period in 2025 as compared to 2024 is related to the increased exploration expenditures, as noted above, incurred by ECRC.

Adjusted net loss increased for the three-month period in 2025, as compared to 2024, primarily due to the increase in exploration expenditures, as noted above, incurred by ECRC.

Adjusted net loss per share declined slightly due to the impact of additional Common Share issuances in 2025.

Six-month period ended December 31, 2025 compared to the six-month period ended December 31, 2024

Except as noted below, the discussion of significant variances for the three-month period also explains the majority of changes for the six-month period, including with respect to net loss and net loss per share for the six-month period ended December 31, 2025:

Exploration expenditures increased for the six-month period in 2025 as compared to 2024, primarily due to field-based costs associated with the 2025 Drilling Program, which was substantially completed by September 30, 2025, as well as expenses related to the Company’s ongoing efforts to update the Elk Creek Project feasibility study.

Change in fair value of earnout shares liability and change in fair value of warrant liabilities both increased for the six-month period ended December 31, 2025, as compared to 2024, reflecting the effect of an increase in the Company’s Common Share price on the financial modeling results for each of these liabilities.

A djusted net loss and adjusted net loss per share both increased for the six-month period in 2025, as compared to 2024, primarily due to the increase in exploration expenditures, as noted above, incurred by ECRC.

Liquidity and Capital Resources

We have no revenue generating operations from which we can internally generate funds.

To date, our ongoing operations have been financed by the sale of our equity securities by way of public and private offerings, convertible securities issuances, the exercise of Options and Warrants, and related party loans.

With respect to currently outstanding Options and Warrants, we believe that exercise of these instruments, and cash proceeds from such exercises, will not occur unless and until the market price for our Common Shares equals or exceeds the related exercise price of each instrument.

As discussed above under “— Recent Corporate Events ”, the Company closed the October 2025 Offering with net proceeds of approximately $139.1 million, after deducting placement agency fees and other offering expenses payable by the Company.

In addition, during the three-month period ended December 31, 2025, the Company issued an aggregate of 3,957,822 Common Shares through the exercise of Warrants and Options by their holders and advances under the Yorkville Equity Facility Financing Agreement, for which the Company received proceeds totaling approximately $14.6 million.

During the period from January 1, 2026 to February 6, 2026, the Company issued an aggregate of 4,527,662 Common Shares through advances under the Yorkville Equity Facility Financing Agreement, for which the Company received proceeds totaling approximately $31.1 million.

The Company expects to use these net proceeds for working capital and general corporate purposes, including to advance efforts to launch construction of the Elk Creek Project and move it to commercial operation.

As of December 31, 2025, the Company had cash of $306.4 million and working capital of $297.9 million, compared to cash of $25.6 million and working capital of $24.8 million on June 30, 2025.

We expect that the Company will operate at a loss for the foreseeable future.

The Company’s current planned cash outflows are approximately $70.0 million to $85.0 million for the next twelve months.

Our planned cash outflows over the next twelve months are expected to consist of expenditures relating to limited, incremental activities to advance certain aspects of the Elk Creek Project by ECRC, corporate overhead costs, and estimated costs related to securing financing necessary for advancement of the Elk Creek Project.

These planned expenditures include expenditures relating to the anticipated completion of an updated resource and reserve estimate and associated mine plan and an updated capital cost estimate in connection with the EXIM application process, infrastructure development, ongoing engineering and metallurgical test work, environmental and permitting activities, community and stakeholder engagement programs, corporate and administrative overhead, and advisory costs related to securing project financing.

The Company will need to secure additional capital to finance construction and achieve commercial production to support its long-term business objectives.

Until sufficient funding for construction is secured, the Company expects to continue advancement activities related to the Elk Creek Project, including incremental engineering and limited underground portal-related work, while maintaining project readiness efforts.

The Company also intends to evaluate strategies and potential investment opportunities that could reduce overall project costs, capital requirements, or execution risk.

The planned corporate overhead costs over the next twelve months are approximately $12.0 million, including Elk Creek property lease commitments, which are $54 through June 30, 2026, and the settlement of outstanding accounts payable as of December 31, 2025.

The estimated financing costs associated with the Elk Creek Project over the next twelve months include, but are not limited to, costs relating to the EXIM application process, the scope of which remains under discussion with EXIM.

On June 6, 2023, the Company announced that it had submitted an application to EXIM for up to $800 million in debt financing (the “EXIM Financing”) to fund the project costs for the Elk Creek Project, under EXIM’s “Make More in America” initiative.

The EXIM Financing is subject to, among other matters, the satisfactory completion of due diligence, the negotiation and settlement of final terms, and the negotiation of definitive documentation.

The Company was informed that its application received approval by the first of three reviews by the EXIM Transaction Review Committee (the “TRC”) on October 2, 2023.

In April 2024, EXIM provided the Company with a preliminary, non-binding indicative term sheet as part of a Preliminary Project Letter (the “PPL”), which also conveyed EXIM’s initial due diligence findings on the Company’s application for the EXIM Financing.

The PPL identified additional project activities to be undertaken by the Company as part of EXIM’s due diligence process.

These included, among other things, an updated mine plan and updated Elk Creek Project capital costs on a final or close-to-final basis reflecting updated process flows.

The 2025 Drilling Program, which started in April 2025 and completed in September 2025, was designed to help meet mineral resource and mineral reserve classification requirements necessary to complete certain of the additional project activities identified by the PPL.

In addition, as previously disclosed, the Company took an additional step in the process by executing a professional services agreement with SLR Consulting to conduct an independent environmental and social review as part of EXIM’s ongoing project due diligence.

The Company continues to meet with EXIM, provide responses to requests for additional information from EXIM and to the consultants that are conducting due diligence on the Company’s application on behalf of EXIM and take steps to complete the additional project activities identified by the PPL.

There can be no assurance as to what further project activities or matters EXIM may request in connection with the application process.

We are currently unable to estimate how long the application process may take, and there can be no assurances that we will be able to successfully negotiate a final commitment of debt financing from EXIM.

We expect our cash balance as of December 31, 2025, as well as the proceeds from Warrant and Option exercises and advances under the Yorkville Equity Facility Financing Agreement that occurred since December 31, 2025, and the reimbursement payments pursuant to the DoD Agreement, to be sufficient to fund our planned expenditures for the next twelve months.

However, additional work is required in order to advance the Elk Creek Project to construction, requiring additional financing.

The technical report summary for the Elk Creek Project prepared in accordance with subpart 1300 of Regulation S-K (“S-K 1300”) and filed as Exhibit 96.1 to the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2025, includes an estimated total upfront capital expenditure for the Elk Creek Project of approximately $1,141.0 million.

The actual amount of capital expenditure required to successfully achieve commercial production at the Elk Creek Project is subject to, among other factors, the timing and actual cost of further exploration, preparing feasibility studies, permitting, engineering and the construction of infrastructure, mining and processing facilities.

In addition, to the extent that EXIM requests further project activities to be undertaken in connection with the diligence process, the Company would require additional funding to complete such activities.

As noted above, the Company’s ability to continue operations, fund our current work plan, and construct and operate the Elk Creek Project is dependent on management’s ability to secure additional financing.

When available, the Yorkville Equity Facility Financing Agreement provides an opportunity for opportunistic share sales to help fund our current work plan.

However, the Yorkville Equity Facility Financing Agreement will expire by its terms on April 1, 2026.

Except for the potential funding from advances under the Yorkville Equity Facility Financing Agreement, as discussed above, and the potential exercise of Options and Warrants, we currently have no further funding commitments or arrangements for additional financing at this time.

Management currently anticipates that it will fund the upfront capital expenditure amount for the Elk Creek Project through a combination of debt and equity financing, with approximately two-thirds of such amount being funded from the net proceeds of debt financing, including the amount of debt that would be represented by the EXIM Financing, if any.

Management is actively pursuing additional sources of debt and equity financing to meet its long-term funding requirements, and while it has been successful in doing so in the past, there is no assurance that we will be able to obtain any such additional financing on acceptable terms, if at all.

Pursuant to the Exchange Agreement, dated as of March 17, 2023 (as amended, supplemented or otherwise modified, the “Exchange Agreement”), by and among NioCorp, ECRC and GX Sponsor II LLC, NioCorp is restricted from issuing equity or equity-linked securities (other than Common Shares) or any preferred equity or non-voting equity if such issuance would adversely impact the rights of the holders of the shares of Class B common stock of ECRC, without the consent of the holders of a majority of the shares of Class B common stock of ECRC.

Notwithstanding the restrictions set forth in the Exchange Agreement, there is significant uncertainty that we would be able to secure any additional financing in the current equity or debt markets.

The quantity of funds to be raised and the terms of any proposed equity or debt financing that may be undertaken will be negotiated by management as opportunities to raise funds arise.

Management may pursue funding sources of both debt and equity financing, including but not limited to the issuance of equity securities in the form of Common Shares, Warrants, subscription receipts, or any combination thereof in units of the Company pursuant to private placements to accredited investors or pursuant to public offerings in the form of underwritten/brokered offerings, registered direct offerings, or other forms of equity financing and public or private issuances of debt securities, including secured and unsecured convertible debt instruments, or secured debt project financing.

Management does not currently know the terms pursuant to which such financings may be completed in the future, but any such financings will be negotiated at arm’s-length.

Future financings involving the issuance of equity securities or derivatives thereof will likely be completed at a discount to the then-current market price of the Company’s securities and will likely be dilutive to current shareholders.

In addition, we could raise funds through the sale of interests in our mineral properties, although current market conditions and other recent worldwide events have substantially reduced the number of potential buyers/acquirers of any such interests.

However, we cannot provide any assurances that we will be able to be successful in raising such funds.

As defined under S-K 1300, we are a development stage issuer and we have incurred losses since our inception.

The Company will require additional capital to meet its long-term operating requirements.

Uncertainty in capital markets, supply chain disruptions, increased interest rates and inflation, and the potential for geographic

recessions have contributed to general global economic uncertainty.

Flow Considerations

Company has historically relied upon debt and equity financings to finance its activities.

Subject to the restrictions set forth

in the Exchange Agreement and the various placement agency agreements with Maxim, the Company may pursue additional debt and/or

equity financing in the medium term;

however, there can be no assurance the Company will be able to obtain any required financing

in the future on acceptable terms, or at all.

Company has limited financial resources compared to its proposed expenditures, no source of operating income, and no assurance

that additional funding will be available to it for current or future projects, although the Company has been successful in the

past in financing its activities through the sale of equity securities.

ability of the Company to arrange additional financing in the future will depend, in part, on the prevailing capital markets conditions,

and its success in developing the Elk Creek Project.

Any quoted market for the Common Shares may be subject to market trends generally,

notwithstanding any potential success of the Company in creating revenue, cash flows, or earnings, and any depression of the trading

price of the Common Shares could impact its ability to obtain equity financing on acceptable terms.

Historically,

the Company has used net proceeds from issuances of Common Shares to provide sufficient funds to meet its near-term exploration

and development plans and other contractual obligations when due.

However, development and construction of the Elk Creek Project

will require substantial additional capital resources.

We do not believe that the credit, liquidity, or market risks with respect thereto have increased as a result of the current market conditions.

However, in order to achieve greater security for the preservation of our capital, we have, of necessity, been required to accept lower rates of interest, which has also lowered our potential interest income.

Operating Activities

During the six months ended December 31, 2025, the Company’s operating activities consumed $7.6 million of cash (2024:

$2.0 million).

The cash used in operating activities for the six months ended December 31, 2025, reflects the Company’s funding of losses of $44.7 million, primarily resulting from increased fair value related to the Earnout Shares and Warrant liabilities, share-based compensation, and other non-cash transactions.

Overall, operational outflows during the six months ended December 31, 2025, increased from the corresponding period of 2024 due to costs and expenditures incurred in connection with the 2025 Drilling Program and the Company's current efforts to update the Elk Creek Project feasibility study.

Going forward, the Company’s working capital requirements are expected to increase substantially in connection with the development of the Elk Creek Project.

Investing Activities
