OVERVIEW

Aptose is a science-driven biotechnology

company advancing first-in-class targeted agents to treat life-threatening cancers, such as AML, high-risk MDS, CLL and other hematologic

malignancies. Based on insights into the genetic and epigenetic profiles of certain cancers and patient populations, Aptose is

building a pipeline of novel oncology therapies directed at dysregulated processes and signaling pathways. Aptose is developing

targeted medicines for precision treatment of these diseases to optimize efficacy and quality of life by minimizing the side effects

associated with conventional therapies. We currently have in development two molecules: luxeptinib (CG-806) and APTO-253, both

being evaluated for safety, tolerability, pharmacokinetics and signals of efficacy in Phase 1 clinical trials. Each molecule is

described below.

Luxeptinib is an orally administered, highly

potent first-in-class FLT3/BTK inhibitor that selectively targets defined clusters of kinases that are operative in hematologic

malignancies. This mutationally agnostic small molecule anticancer agent is currently being evaluated in a Phase 1a/b study for

the treatment of patients having B-cell malignancies including classic CLL, SLL and certain NHL that are resistant/refractory/intolerant

to other therapies. In addition, Aptose received IND allowance and initiated patient dosing in a Phase 1a/b study to develop

luxeptinib for the treatment of patients with R/R AML, including the emerging populations resistant to FLT3 inhibitors. In this

trial of patients with R/R AML, the luxeptinib starting dose of 450 mg BID was selected because the plasma from B-cell cancer patients

at that dose completely inhibited phospho-FLT3, suggesting that this starting dose might be active in the AML patient population,

and that dose escalation is planned to identify an optimal dose for treating a breadth of AML patients. It is important to note

that luxeptinib now is undergoing formal clinical development in both lymphoid and myeloid hematologic malignancies.

APTO-253 is a first-in-class small molecule

therapeutic agent that clinically inhibits expression of the MYC oncogene without causing, to date, general myelosuppression of

the bone marrow. The MYC oncogene is overexpressed across many hematologic cancers, including AML and certain B cell malignancies,

as well as certain solid tumor indications. MYC acts as a transcription factor that regulates cell growth, proliferation, differentiation

and apoptosis, and overexpression of MYC amplifies new sets of genes to promote survival of cancer cells. APTO-253 suppresses expression

of the MYC oncogene in AML cells and depletes those cells of the MYC oncoprotein, leading to apoptotic cell death. APTO-253 is

currently being evaluated in a Phase 1a/b study for the treatment of patients with R/R AML and high-risk MDS. APTO-253 may serve

as a safe and effective MYC inhibitor for AML/MDS patients that combines well with other agents and does not significantly impact

the normal bone marrow.

Impact of COVID 19 on our Research

Programs:

We are advancing first-in-class targeted

agents to treat life-threatening cancers that, in most cases, are not elective for patients and require immediate treatment. However,

COVID-19 has caused global economic and social disruptions that could adversely affect our ongoing or planned research and development

and clinical trial activities including enrollment of patients in our ongoing clinical trials, collection and analysis of patient

data and eventually, the reporting of top-line results from our trials.

Our team proactively addressed these new

challenges swiftly and appropriately, implementing safeguards and procedures to ensure both the safety of our employees and stakeholders,

and accommodate the potential challenges due to COVID-19. Aptose was early in directing its employees to work-from-home and provided

the tools to minimize productivity disruptions. Our clinical operations team reached out to active and future clinical sites to

determine their needs and challenges and assist where possible, including virtual monitoring of patients, which reduces patients’

visits. We also have contacted our drug manufacturers to identify any potential supply chain disruptions and are adjusting accordingly.

During the early part of the first quarter of 2020, we began to carefully monitor the potential impact of COVID-19, and on a regular

basis, we communicated with investigators at our clinical sites to gain an evolving understanding of competing COVID-19 related

activities and clinical trial related activities.

In the beginning of April 2020, we learned

that some of our larger clinical sites that are impacted by COVID-19 may either postpone or face delays in the enrollment of patients

on all on-going clinical trials due to a number of factors, including the re-allocation of resources and to avoid clinical trial

patients being exposed to COVID-19. Such measures taken at the clinical sites could lead to a slowdown in the enrollment of patients

on our trials at these sites. To minimize the impact of COVID-19, we focused efforts on our other larger clinical sites and regional

cancer care sites that are not/less impacted by COVID-19 to recruit patients into the fourth cohort. While it is difficult to estimate

the duration and impact of COVID-19 on the larger clinical sites and regional cancer care sites, as of the date of this report,

we have not experienced and do not foresee material delays to the enrollment of patients or timelines for the luxeptinib Phase 1a/b

B-cell malignancy trial due to the variety of clinical sites that we have actively recruited for this trial. APTO-253, which is

administered intravenously, requires the need for hospital / clinical site resources to assist and monitor patients during each

infusion and based on the current conditions caused by COVID-19, future enrollment of patients on this trial is likely to be negatively

impacted.

PROGRAM UPDATES

Luxeptinib (CG-806)

Indication and Clinical Trials:

Luxeptinib is being developed with the

intent to deliver the agent as an oral therapeutic for the treatment of R/R AML and for the treatment of a spectrum of B cell malignancies

(including but not limited to CLL, SLL and NHL).

On March 25, 2019, we announced that the

FDA granted Aptose IND allowance to initiate its Phase 1a/b clinical trial for luxeptinib. The clinical trial is a multicenter,

open label, dose-escalation study with additional optional expansion cohorts to assess the safety, tolerability, pharmacokinetics

and pharmacodynamic effects, and prelimnary efficacy of luxeptinib in patients with CLL, SLL or NHL. In this study, luxeptinib

is administered in gelatin capsules twice daily (BID during a 28-day cycle.

As of the date of this report, we have initiated thirty clinical

sites for the Phase 1a/b trial in patients with CLL/SLL or NHL which include specialty regional cancer care centers as well as

large hospitals and key academic institutions. As of the date of this report, we have completed the first, second, third and fourth

dose levels (150 mg, 300 mg, 450 mg and 600 mg BID, respectively). Cohort 5 (750mg) enrollment is ongoing. Under an FDA-approved

accelerated titration protocol, only one patient was required at each of the first two dose levels, followed by three patients

at each dose level thereafter. Intra-patient dose escalation is allowed if the higher dose is safe in three or more patients,

and additional patients may be enrolled at dose levels previously declared safe. To date, we have reported that among enrolled

patients with an array of B-cell malignancies, three classic CLL patients have received luxeptinib and all three demonstrated

inhibition of phospho-BTK and “on-target” lymphocytosis and modest tumor reductions in different tumor types, indicating

target engagement and pharmacologic activity of luxeptinib. As luxeptinib moves from low/intermediate dose levels and into the

higher dose levels, it is hoped that an optimal dose can be selected that demonstrates formal clinical responses without excessive

toxicity.

We are also advancing luxeptinib into myeloid

malignancies, with an initial focus on AML, in a separate Phase 1a/b trial. On June 29, 2020, we announced that we had received

allowance from the FDA to proceed into a study in R/R AML with a starting dose of 450 mg BID, and subsequently on October 19, 2020,

announced that we had initiated dosing of the first patient with AML. As of the date of this report we have initiated six clinical

sites for the Phase 1a/b trial and dosing continues at the 600 mg dose cohort.

The clinical trial is a multicenter, open

label, dose-escalation study with additional optional expansion cohorts to assess the safety, tolerability, pharmacokinetics and

pharmacodynamic effects, and preliminary efficacy of luxeptinib in patients with R/R AML. In this study, luxeptinib is administered

in gelatin capsules BID during a 28-day cycle. Our strategy was to identify a starting dose of luxeptinib that we believe could

be therapeutically active in critically ill patients with R/R AML. In our ongoing Phase 1a/b study in patients with CLL and other

B-cell malignancies, 450 mg BID luxeptinib delivered plasma levels potently inhibited phospho-FLT3 in a plasma inhibitory activity

(PIA) reporter cell assay, suggesting that the 450 mg BID dose may be active in patients with AML. Aptose plans to dose escalate

beyond the 450 mg BID dose level, provided the 450 mg BID dose level is safe and well tolerated in R/R AML patients. Based on strong

preclinical evidence of luxeptinib’s activity against AML – including demonstration of mutation-agnostic and genotype-agnostic

potency, particularly compared against other FLT3 inhibitors, and its ability to safely cure AML in murine leukemia models –

we believe that luxeptinib may offer hope to the fragile and difficult-to-treat AML patient population. The FDA has granted orphan

drug designation to luxeptinib for the treatment of patients with AML. Orphan drug designation is granted by the FDA to encourage

companies to develop therapies for the treatment of diseases that affect fewer than 200,000 individuals in the United States. Orphan

drug status provides research and development tax credits, an opportunity to obtain grant funding, exemption from FDA application

fees and other benefits. The orphan drug designation also provides us with seven additional years of marketing exclusivity in this

indication.

Manufacturing:

During fiscal years 2017 and 2018, we created

a scalable chemical synthetic route for the manufacture of luxeptinib drug substance and have scaled the manufacture of API (active

pharmaceutical ingredient, or drug substance) to multi-kg levels, we completed the manufacture of a multi-kg batch of API under

GMP conditions as our API supply for our first-in-human clinical trials, and we manufactured under GMP conditions two dosage strengths

of capsules to serve as our clinical supply in those human studies. During fiscal 2019 and 2020, we completed successful manufacture

of multiple batches of API and drug product, and planned numerous GMP production campaigns to supply the ongoing trial and planned

trials into the future. To date we have been able to manufacture API and capsules to support clinical supplies under GMP conditions.

We are continuing our manufacturing campaigns in the current 2021 fiscal period and continue scale-up and tech transfer activities

to support additional manufacturing capacity for the ongoing and planned clinical trials of luxeptinib. Additional research and

development funds are being utilized to support exploratory formulation studies in an ongoing effort to craft a superior formulation

for later stage development of luxeptinib.

Preclinical Program Updates:

We have completed several non-clinical

studies that demonstrate the highly differentiated profile of luxeptinib. Key studies that have been presented at scientific forums

are as follows:

APTO-253

APTO-253, a small molecule inhibitor of

MYC gene expression, is being evaluated by Aptose in a Phase 1a/b clinical trial in patients with R/R hematologic malignancies,

particularly R/R AML and high-risk MDS. The Phase 1b, multicenter, open-label, dose-escalation clinical trial of APTO-253 is designed

to assess the safety, tolerability, pharmacokinetics and pharmacodynamic responses and efficacy of APTO-253 as a single agent and

determine the recommended Phase 2 dose. APTO-253 is being administered once weekly, over a 28-day cycle. The dose escalation stage

of the study could potentially enroll up to 20 patients with R/R AML or high-risk MDS. The study is designed to then transition,

as appropriate, to single-agent expansion cohorts in R/R AML and/or high-risk MDS.

As of the date of this report, we have

multiple active sites recruiting patients in the dose escalation stage of the trial. As of the date of this report, we have completed

enrollment and treatment of patients on the first, second, third and fourth dose levels (20, 40, 66, and 100 mg/m2,

respectively). Under an FDA-approved accelerated titration protocol, only one patient was required at each of the first two dose

levels, followed by three patients at each dose level thereafter. Aptose is currently enrolling and treating patients in the fifth

dose level (150 mg/m2) of APTO-253. During the second quarter of 2020, the FDA allowed an amendment for Aptose to initiate

more aggressive dose escalations with APTO-253, provided the tolerability profile remains favorable. The first four dosing cohorts

have enrolled a mix of patients with AML and MDS. To date, we have observed meaningful reductions in MYC expression in peripheral

blood mononuclear cells (PBMCs) from treated patients with AML and MDS, demonstrating MYC target engagement and mechanistic proof

of concept in different indications.

Manufacturing:

We are continuing to manufacture additional

drug substance and drug product for use in the ongoing trial.

We are exploring additional drug delivery

methods for APTO-253 and plan to initiate additional non-clinical studies for solid tumor and hematologic cancer development. As

preparing, submitting, and advancing applications for regulatory approval, developing drugs and drug product and clinical trials

are sometimes complex, costly, and time-consuming processes, an estimate of the future costs is not reasonable at this time.

Preclinical data presented at scientific

forums are as follows:

While as of the date of this report we

have not experienced any material delays in initiating our luxeptinib Phase 1 clinical study in AML due to COVID-19, we are conducting

site initiation visits remotely which could result in delays in site activations and negatively impact this trial. Additionally,

COVID-19 could negatively impact patient enrollment if our clinical sites are unable to enroll patients due to either a lack of

administrative resources at their sites or decisions made at the clinical sites to limit patient exposure to COVID-19.

As of the date of this report, we have

not experienced material delays in the manufacturing of luxeptinib or APTO-253 related to COVID-19. Should our manufacturers experience

shortages in staffing or be required to shut down their facilities due to COVID-19 for an extended period of time, our trials may

be negatively impacted.

LIQUIDITY AND CAPITAL RESOURCES

We are an early stage development company

and we currently do not earn any revenues from our drug candidates. The continuation of our research and development activities

and the commercialization of the targeted therapeutic products are dependent upon our ability to successfully finance and complete

our research and development programs through a combination of equity financing and payments from strategic partners. We have no

current sources of significant payments from strategic partners.

Sources of liquidity:

The following table presents our cash and

cash equivalents, investments and working capital as at December 31, 2020 and 2019.

(in thousands) Balances at December 31, 2020 Balances at December 31, 2019

Working capital represents primarily cash,

cash equivalents, investments, prepaid expenses and other current assets less current liabilities.

We believe that our cash, cash equivalents

and investments on hand at December 31, 2020 will be sufficient to finance our operations for at least 12 months from the issuance

date of these financial statements. Our cash needs for the next twelve months include estimates of the number of patients and rate

of enrollment of our clinical trials, the amount of drug product that we will require to support our clinical trials, and our general

corporate overhead costs to support our operations, and our reliance on our manufacturers. We have based these estimates on assumptions

and plans which may change and which could impact the magnitude and/or timing of operating expenses and our cash runway.

Since our inception, we have financed our

operations and technology acquisitions primarily from equity financing, proceeds from the exercise of warrants and stock options,

and interest income on funds held for future investment.

On July 20, 2020 and August 10, 2020, the

Company completed a confidentially marketed public offering (“CMPO”), with Piper Sandler & Co. (“Piper Sandler”)

as the representative of the underwriters, through the issuance of, in the aggregate, 11,854,472 Common Shares for gross proceeds

of $62.2 million (approximately $58.2 million net of share issue costs).

On May 5, 2020, the Company entered an

“at-the-market” equity distribution agreement with Piper Sandler and Canaccord Genuity LLC (“Canaccord Genuity”)

acting as co-agents (the “2020 ATM Facility”). Under the terms of the 2020 ATM Facility, the Company may, from time

to time, sell Common Shares having an aggregate offering value of up to $75 million through Piper Sandler and Canaccord Genuity

on the Nasdaq Capital Market. During the year ended December 31, 2020, the Company did not issue any shares under the 2020 ATM

Facility.

During the year ended December 31, 2019,

the Company completed two CMPOs, with RBC Capital Markets, LLC (“RBC Capital Markets”) and Canaccord Genuity, as representatives

of the underwriters, and Piper Jaffray & Co (now Piper Sandler) as the representative of the underwriters, respectively, through

the issuance of, in the aggregate, 30,043,750 Common Shares for aggregate gross proceeds of $95.45 million (approximately $88.18

million net of share issue costs). The Company also raised capital pursuant to two separate share purchase agreements with Aspire

Capital Fund, LLC (“Aspire Capital”) through the issuance of an aggregate of 7,302,433 Common Shares for aggregate

gross proceeds of $14.4 million. We do not expect that COVID-19 will have a significant impact on our liquidity and capital resources

and we are not incurring significant additional costs to support our ongoing operations during this time. We have not entered into

long term manufacturing contracts and should there be a delay in our trials we have flexibility to reduce future planned manufacturing

campaigns without incurring additional costs.

We expect that we will need to raise additional

capital or incur indebtedness to continue to fund our operations in the future. In December 2019, we filed a short form base shelf

prospectus (the “Base Shelf”) that allows us to distribute, upon the filing of prospectus supplements, up to $200,000,000

of Common Shares, warrants, or units comprising any combination of Common Shares and warrants. The Base Shelf was declared effective

by the SEC on January 9, 2020 and expires on January 9, 2023.

Our ability to raise additional funds could

be affected by adverse market conditions, the status of our product pipeline, possible delays in enrollment in our trial related

to COVID-19, and various other factors and we may be unable to raise capital when needed, or on terms favorable to us. If the necessary

funds are not available, we may need to delay, reduce the scope of, or eliminate some of our development programs, potentially

delaying the time to market for any of our product candidates.

Cash flows:

The following table presents a summary

of our cash flows for the years ended December 31, 2020 and 2019:

For the Years Ended,

Net cash provided by (used in):

Effect of exchange rates changes on cash and cash equivalents 7 23

Net increase in cash and cash equivalents $ 37,551 $ 64,543

Cash used in operating activities:

Our cash used from operating activities

for the years ended December 31, 2020 and 2019 was approximately $33.9 million and $21.6 million, respectively. Net cash used

in operating activities was higher in the year ended December 31, 2020 as compared with the year ended December 31, 2019 resulting

mostly from a higher net loss in the current year. See “Results of Operations”. Our uses of cash for operating activities

for both years consisted primarily of salaries and wages for our employees, facility and facility-related costs for our offices

and laboratories, fees paid in connection with preclinical and clinical studies, drug manufacturing costs, laboratory supplies

and materials, and professional fees.

We do not expect to generate positive cash

flow from operations for the foreseeable future due to additional research and development costs, including costs related to drug

discovery, preclinical testing, clinical trials, and manufacturing, as well as operating expenses associated with supporting these

activities, and potential milestone payment to our collaborators. It is expected that negative cash flow will continue until such

time, if ever, that we receive regulatory approval to commercialize any of our products under development and/or royalty or milestone

revenue from any such products exceeds expenses.

Cash flow from investing activities:

Our cash provided by investing activities

for the year ended December 31, 2020 was $12.6 million, and consisted of maturities of investments of $12.7 million and

purchases of property and equipment of $79 thousand. Our cash used by investing activities for the year ended December 31, 2019

was $17.4 million, and consisted of net purchases of investments of $17.3 million and purchases of property and equipment

of $102 thousand.

The composition and mix of cash, cash equivalents

and investments is based on our evaluation of conditions in financial markets and our near-term liquidity needs. We have exposure

to credit risk, liquidity risk and market risk related to our investments. The Company manages credit risk associated with its

cash and cash equivalents and investments by maintaining minimum standards of R1-low or A-low investments. The Company invests

only in highly rated corporations and treasury bills which are capable of prompt liquidation. The Company manages its liquidity

risk by continuously monitoring forecasts and actual cash flows. The Company is subject to interest rate risk on its cash and cash

equivalents and investments. The Company does not believe that the results of operations or cash flows would be affected to any

significant degree by a sudden change in market interest rates relative to interest rates on the investments, owing to the relative

short-term nature of the investments.

Cash flow from financing activities:

Our cash flow from financing activities

for the year ended December 31, 2020 was approximately $58.8 million, consisted mostly of the CMPO we completed in July and August

2020 as described above and of proceeds from the exercise of stock options of $573 thousand. Net cash provided by financing

activities in the year ended December 31, 2019 reflects mostly:

vi) proceeds from the exercise of stock options of $718 thousand.

At-The-Market Facilities

On May 5, 2020, the Company entered into

an equity distribution agreement with Piper Sandler and Canaccord Genuity acting as co-agents in connection with the 2020 ATM Facility.

Under the terms of the 2020 ATM Facility, the Company may, from time to time, sell Common Shares having an aggregate offering value

of up to $75 million through Piper Sandler and Canaccord Genuity on the Nasdaq Capital Market. During the year ended December 31,

2020, the Company did not issue any shares under the 2020 ATM Facility.

On May 24, 2019, we entered an at-the-market

equity facility (the “2019 ATM Facility”) with Piper Jaffray & Co. (now Piper Sandler) and Canaccord Genuity, acting

as co-agents. The 2019 ATM Facility replaced the previous facility that we had entered into with Cantor Fitzgerald (the “2018

ATM Facility”). The 2019 ATM Facility allowed us to instruct our co-agents to offer up to approximately 20.2 million

Common Shares, having an aggregate offering value of up to $40.0 million, at the prevailing market price from time to time. The

Company did not issue any shares under the 2019 ATM Facility, and on December 16, 2019, the Company terminated the 2019 ATM Facility.

On March 27, 2018, the Company entered

into an equity distribution agreement with Cantor Fitzgerald acting as sole agent in connection with the 2018 ATM Facility. Under

the terms of the 2018 ATM Facility, the Company was allowed, from time to time, to sell Common Shares having an aggregate offering

value of up to $30 million through Cantor Fitzgerald on the Nasdaq Capital Market. During the year ended December 31, 2019, the

Company issued 77,349 shares under the 2018 ATM Facility at an average price of $2.37 for gross proceeds of $183 thousand ($178

thousand net of share issue costs). On a cumulative basis to December 31, 2019, the Company had raised a total of $11.2 million

gross proceeds ($10.9 million net of share issue costs) under the 2018 ATM Facility. The Company terminated this agreement on May

24, 2019.

Common Share Purchase Agreements

On May 30, 2018, the Company entered into

a common share purchase agreement to sell up to $20.0 million of Common Shares to Aspire Capital over approximately 30 months (the

“2018 Aspire Purchase Agreement”). Pursuant to the terms of this agreement, on June 8, 2018, the Company issued 170,261

Common Shares to Aspire Capital in consideration for entering into the 2018 Aspire Purchase Agreement for a total cost of $600

thousand. During the year ended December 31, 2019, the Company issued 5,502,433 Common Shares to Aspire Capital pursuant to

the 2018 Aspire Purchase Agreement at an average price of $1.82 per Common Share for gross and net proceeds of $10 million. On

a cumulative basis, the Company raised a total of approximately $11.9 million gross and net proceeds under the 2018 Aspire Purchase

Agreement. As of May 24, 2019 the Company had issued 6,409,980 Common Shares, the maximum number of Common Shares issuable under

this facility without shareholder approval, and the 2018 Aspire Purchase Agreement was accordingly terminated.

On May 7, 2019, the Company entered into

the a common share purchase agreement with Aspire Capital (the “2019 Aspire Purchase Agreement”), which provided that,

upon the terms and subject to the conditions and limitations set forth therein, Aspire Capital was committed to purchase up to

an aggregate of $20 million of Common Shares over approximately 30 months. Pursuant to the terms of this agreement, on May 13,

2019, the Company issued 171,428 Common Shares to Aspire Capital in consideration for entering into the 2019 Aspire Purchase Agreement

for a total cost of $360 thousand. During the period from May 7, 2019 up to December 16, 2019, the date the 2019 Aspire Purchase

Agreement was terminated, the Company issued 1,800,000 Common Shares under the agreement at an average price of $2.43 per Common

Share for gross and net proceeds of $4.4 million.

Contractual Obligations and Off-Balance Sheet Financing

As at December 31, 2020, we have not entered

into any off-balance sheet arrangements.

The Company enters into research, development

and license agreements in the ordinary course of business where the Company receives research services and rights to proprietary

technologies. Milestone and royalty payments that may become due under various agreements are dependent on, among other factors,

clinical trials, regulatory approvals and ultimately the successful development of a new drug, the outcome and timing of which

is uncertain.

Under the license agreement with CG with

regards to the Rights (other than the China Rights), the Company has obligations for development milestones of $16 million related

to the initiation of Phase 2 and pivotal clinical trials, and regulatory milestones totaling $44 million. The Company also has

an obligation to pay royalty payments on sales of commercialized product. The timing of any milestone or royalty payments that

may become due is not yet determinable.

Under the license agreement with CG with

regards to the China Rights, we entered into a license agreement with CG to gain an exclusive license to CG-806 in China (including

the People’s Republic of China, Hong Kong and Macau). The Company has future obligations of development milestones of $6

million related to approval of an IND and to the initiation of Phase 2 and pivotal clinical trials, and regulatory milestones totaling

$20 million. The Company also has an obligation to pay sales milestones and royalty payments on sales of commercialized product.

The timing of any milestone or royalty payments that may become due is not yet determinable.

RESULTS OF OPERATIONS

A summary of the results of operations

for the years ended December 31, 2020 and 2019 is presented below:

Year ended December 31,

Revenues $ — $ —

Unrealized gain/(loss) on securities available-for-sale (18 ) 18

Basic and diluted loss per Common Share $ (0.67 ) $ (0.52 )

Net loss of $55.2 million for the year

ended December 31, 2020 increased by approximately $28.9 million as compared with $26.3 million for the year ended December 31,

2019, primarily as a result of an increase of $19.1 million in stock-based compensation in the current period, a combined increase

in program costs and related labor costs of approximately $9.8 million on our luxeptinib development program and higher cash-based

general and administrative expenses of approximately $549 thousand. These expenses were partially offset by lower costs of $545

thousand on our APTO-253 development programs.

Research and Development Expenses

The research and development (“R&D”)

expenses for the years ended December 31, 2020 and 2019 were as follows:

Year ended December 31,

Depreciation of equipment 17 30

R&D expenses increased by $12.5 million

to $29.3 million for the year ended December 31, 2020 as compared with $16.8 million for the comparative period in 2019. Changes

to the components of our R&D expenses presented in the table above are primarily as a result of the following activities:

General and Administrative Expenses

The general and administrative expenses

for the years ended December 31, 2020 and 2019 are as follows:

Year ended December 31,

General and administrative, excluding items below: $ 8,627 $ 8,078

Depreciation of equipment 135 122

General and administrative expenses for

the year ended December 31, 2020 were approximately $26.5 million as compared with $10.0 million for the comparative period in

2019, an increase of approximately $16.5 million. The increase was primarily as a result of the following:

COVID-19 did not have a significant impact

on our results of operations for the year ended December 31, 2020. We have not experienced and do not foresee material delays to

the enrollment of patients or timelines for the luxeptinib Phase 1a/b trial due to the variety of clinical sites that we have actively

recruited for this trial. Similarly, we do not expect our enrollment of the luxeptinib AML trial to be negatively impacted by COVID-19

as we plan to use a variety of clinical sites for this trial as well. APTO-253, which is administered intravenously, requires the

need for hospital / clinical site resources to assist and monitor patients during each infusion and, based on the current conditions

caused by COVID-19, future enrollment of patients on this trial is likely to be negatively impacted. As of the date of this report,

we have not experienced material delays in the manufacturing of luxeptinib or APTO-253 related to COVID-19. Should our manufacturers

be required to shut down their facilities due to COVID-19 for an extended period of time, our trials may be negatively impacted.

CRITICAL ACCOUNTING POLICIES

Critical Accounting Policies and Estimates

We periodically review our financial reporting

and disclosure practices and accounting policies to ensure that they provide accurate and transparent information relative to the

current economic and business environment. As part of this process, we have reviewed our selection, application and communication

of critical accounting policies and financial disclosures. Management has discussed the development and selection of the critical

accounting policies with the Audit Committee of the Board, and the Audit Committee has reviewed the disclosure relating to critical

accounting policies in this MD&A.

Significant accounting judgments and estimates

Management’s assessment of our ability

to continue as a going concern involves making a judgment, at a particular point in time, about inherently uncertain future outcomes

and events or conditions. Please see the “Liquidity and Capital Resources” section in this document for a discussion

of the factors considered by management in arriving at its assessment.

Other important accounting policies and

estimates made by management are the estimates related to prepaid and accrued R&D activities, the valuation of contingent liabilities,

the valuation of tax accounts, and the assumptions used in determining the valuation of share-based compensation.

Research and Development Activities:

R&D costs are expensed as incurred. R&D

costs consist primarily of salaries and benefits, stock-based compensation, manufacturing, contract services, clinical trials,

and research related overhead. Non-refundable advance payments for goods and services that will be used in future research

are recorded in prepaid and other assets and are expensed when the services are performed.

The Company records expenses for research

and development activities based on Management’s estimates of services received and efforts expended pursuant to contracts

with vendors that conduct research and development on Aptose’s behalf. The financial terms vary from contract to contract

and may result in uneven payment flows as compared with services performed or products delivered. As a result, the Company is required

to estimate research and development expenses incurred during the period, which impacts the amount of accrued expenses and prepaid

balances related to such costs as of each balance sheet date. Management estimates the amount of work completed through discussions

with internal personnel and external service providers as to the progress or stage of completion of the services. Management makes significant judgments and estimates in determining the accrued balance in each

reporting period. As actual costs become known, the Company adjusts the accrued estimates.

Although Management does not expect our

estimates to be materially different from amounts actually incurred, if the estimates of the status and timing of services performed

differ from the actual status and timing of services performed, it could result in the Company reporting amounts that are too high

or too low in any particular period. To date, there have been no material differences between the estimates of such expenses and

the amounts actually incurred.

Valuation of contingent liabilities:

The Company utilizes considerable judgment

in the measurement and recognition of provisions and the Company’s exposure to contingent liabilities. Judgment is required

to assess and determine the likelihood that any potential or pending litigation or any and all potential claims against the Company

may be successful. The Company must estimate if an obligation is probable, as well as quantify the possible economic cost of any

claim or contingent liability. Such judgments and assumptions are inherently uncertain. The increase or decrease of one of these

assumptions could materially increase or decrease the fair value of the liability and the associated expense.

Valuation of tax accounts:

Uncertainties exist with respect to the

interpretation of complex tax regulations and the amount and timing of future taxable income. Currently, the Company has deductible

temporary differences which would create a deferred tax asset. Deferred tax assets are recognized for all deductible temporary

differences to the extent that it is probable that future taxable profit will be available against which the deductible temporary

differences can be utilized. Management judgment is required to determine the amount of deferred tax assets that can be recognized,

based upon the likely timing and the level of future taxable profits together with future tax planning strategies. To date, the

Company has determined that none of its deferred tax assets should be recognized. The Company’s deferred tax assets are mainly

comprised of its net operating losses from prior years and prior year research and development expenses not yet deducted for income

tax purposes. These tax pools relate to entities that have a history of losses, have varying expiry dates, and may not be used

to offset taxable income. As well, there are no taxable temporary differences or any tax planning opportunities available that

could partly support the recognition of these losses as deferred tax assets. The generation of future taxable income could result

in the recognition of some portion or all of the remaining benefits, which could result in an improvement in the Company’s

results of operations through the recovery of future income taxes.

Valuation of share based compensation:

Management measures the costs for share

based payments using market-based option valuation techniques. Assumptions are made and judgment is used in applying valuation

techniques. These assumptions and judgments include estimating the future volatility of the share price, expected dividend yield,

and expected life of the options. The Company uses historical data to estimate the expected dividend yield and expected volatility

of its Common Shares in determining the fair value of stock options. The expected life of the options represents the estimated

length of time the options are expected to remain outstanding. Such judgments and assumptions are inherently uncertain. The increase

or decrease of one of these assumptions could materially increase or decrease the fair value of share based payments and share

purchase warrants issued and the associated expense.

The weighted average assumptions that were

used in the Black Scholes option pricing model to determine the fair value of stock options granted during the periods ended December

31, 2020 and 2019, respectively, are presented in Note 12 to the consolidated financial statements.

Leases:

Effective January 1, 2019, the Company

adopted Financial Accounting Standards Board, or FASB, standard ASU No. 2016-02, “Leases (Topic 842)”. The Company’s

operating leases of tangible property with terms greater than twelve months are recognized as right of use assets, which represents

the lessee’s right to use, or control the use of, a specified asset for the lease term, and a corresponding lease liability,

which represents the lessee’s obligation to make lease payments under a lease, measured on a discounted basis. The Company

adopted the new standard using the alternative transition method, which permits a company to use its effective date as the date

of initial application without restating comparative period financial statements. Landlord inducements in the form of free rent

periods are netted against lease payments to the landlord in measuring right-of-use assets and lease liabilities.

Impact of adoption:

As a result of adopting Topic 842, we recorded

as of January 1, 2019, a right of use asset of approximately $1.570 million, and a lease liability of approximately $1.647 million.

Upon adoption, landlord inducements of approximately $78 thousand were de-recognized, and a corresponding adjustment was made to

right-of-use assets.

Updated share information

As at March 23, 2021, we had 88,885,238 Common Shares issued and

outstanding. In addition, there were 14,643,053 Common Shares issuable upon the exercise of outstanding stock

options.

ITEM 7A. QUALITATIVE AND QUANTITATIVE

DISCLOSURES ABOUT MARKET RISK

Under SEC rules and regulations, as a smaller

reporting company, we are not required to provide this information.

ITEM 8. FINANCIAL STATEMENTS

AND SUPPLEMENTARY DATA

The financial statements required by this

item are included in the Exhibits to this Annual Report on Form 10-K.

ITEM 9. CHANGES IN AND DISAGREEMENTS

WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

As of the end of our fiscal year ended

December 31, 2020, an evaluation of the effectiveness of our “disclosure controls and procedures” (as such term is

defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) was carried out by our management, with the participation of our

principal executive officer and principal financial officer. Based upon that evaluation, our principal executive officer and principal

financial officer have concluded that as of the end of that fiscal year, our disclosure controls and procedures are effective to

ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is (i) recorded,

processed, summarized and reported within the time periods specified in SEC rules and forms and (ii) accumulated and communicated

to our management, including our principal executive officer and principal financial officers, to allow timely decisions regarding

required disclosure.

It should be noted that while our principal

executive officer and principal financial officer believe that our disclosure controls and procedures provide a reasonable level

of assurance that they are effective, they do not expect that our disclosure controls and procedures or internal control over financial

reporting will prevent all errors or fraud. A control system, no matter how well conceived or operated, can provide only reasonable,

not absolute, assurance that the objectives of the control system are met.

Our management is responsible for establishing

and maintaining adequate internal control over financial reporting as such term is defined in Exchange Act Rule 13a-15(f). Internal

control over financial reporting is a process designed under the supervision and with the participation of our management, including

our principal executive and financial officer, to provide reasonable assurance regarding the reliability of financial reporting

and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in

the United States of America.

As of December 31, 2020, our management

assessed the effectiveness of our internal control over financial reporting using the criteria set forth by the Committee of Sponsoring

Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013 Framework). Based on this assessment, our

management concluded that, as of December 31, 2020, our internal control over financial reporting was effective based on those

criteria. We are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K under the Securities Act.

For as long as we continue to be a smaller reporting company, we may take advantage of exemptions from various reporting requirements

that are applicable to other public companies that are not smaller reporting companies.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL

REPORTING

There were no changes in our internal control

over financial reporting (as defined in Rule 13a-15(f) under the 1934 Act) during our fiscal quarter ended December 31, 2020, that

have materially affected, or are reasonably likely to materially affect, our internal

control over financial reporting.

Aptose

Biosciences Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated

statements of financial position of Aptose Biosciences Inc. and subsidiaries (the Company) as of December 31, 2020 and 2019, the

related consolidated statements of loss and comprehensive loss, changes in shareholders’ equity, and cash flows for each

of the years in the two-year period ended December 31, 2020, and the related notes (collectively, the consolidated financial statements).

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company

Source: SEC EDGAR (public domain) · 10-K for the period ended 2020-12-31, filed 2021-03-23 · accession 0001171843-21-002006

Filing HTML rendered to line-structured narrative text by the shipped reducer (datafeeds.edgar_fulltext.visible_text, keep_table_headers=True): scripts and inline-XBRL headers are dropped, and table content is reduced to its short label cells — numeric table data is not rendered and is therefore not counted. The same rendering is used for every year, so a year-over-year comparison is like for like.

The text is our rendering of the filing, not a facsimile: original pagination, typography and tables are not reproduced, and the numbers live in the financial statements (FA).

The outline locates item HEADINGS in this document. Only Items 1A and 7 have certified boundaries elsewhere in the terminal (the redline and the narrative-overlap number); every span here runs from one heading found to the next heading found.

How the outline was chosen. It is the longest chain of item headings that runs forward through both the document and the standard item order: 20 headings are on that chain and 16 further heading-shaped lines are not — the table-of-contents echo of every item, cross-references and exhibit-list mentions. Each entry's length is measured from its heading to the next heading on the chain.
