NOTES TO CONDENSED FINANCIAL STATEMENTS
(Unaudited)
1. Organization and Basis of Presentation
Business Organization and Overview
Cardiff Oncology, Inc. ("Cardiff Oncology" or the "Company") headquartered in San Diego, California, is a clinical-stage biotechnology company leveraging Polo-like Kinase 1 ("PLK1") inhibition to develop novel therapies across a range of cancers with the greatest unmet medical need, including KRAS-mutated metastatic colorectal cancer, metastatic pancreatic cancer and metastatic castration-resistant prostate cancer. The Company's common stock is listed on the Nasdaq Capital Market under the ticker symbol "CRDF".
Basis of Presentation
The accompanying unaudited interim condensed financial statements of Cardiff Oncology have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and the rules and regulations of the Securities and Exchange Commission ("SEC") related to a quarterly report on Form 10-Q. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations. The unaudited interim condensed financial statements reflect all adjustments consisting of normal recurring adjustments which, in the opinion of management, are necessary for a fair statement of the Company's financial position and the results of its operations and cash flows for the periods presented. The unaudited condensed balance sheet at December 31, 2021, has been derived from the audited financial statements at that date but does not include all of the information and disclosures required by GAAP for annual financial statements. The operating results presented in these unaudited interim condensed financial statements are not necessarily indicative of the results that may be expected for any future periods. These unaudited interim condensed financial statements should be read in conjunction with the audited financial statements and the notes thereto for the year ended December 31, 2021, included in the Company's annual report on Form 10-K filed with the SEC on February 24, 2022.

Liquidity

The Company has incurred net losses since its inception and has negative operating cash flows. As of June 30, 2022, the Company had $122.0 million in cash, cash equivalents and short-term investments and believes it has sufficient cash to meet its funding requirements for at least the next 12 months following the issuance date of these financial statements.

For the foreseeable future, the Company expects to continue to incur losses and require additional capital to further advance its clinical trial programs and support its other operations. The Company cannot be certain that additional funding will be available on acceptable terms, or at all. To the extent that the Company can raise additional funds by issuing equity securities, the Company's stockholders may experience additional dilution.

2. Summary of Significant Accounting Policies
During the six months ended June 30, 2022, there have been no changes to the Company's significant accounting policies as described in its Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

Net Loss Per Share
Basic and diluted net loss per common share is determined by dividing net loss applicable to common stockholders by the weighted-average common shares outstanding during the period. Preferred dividends are included in net loss attributable to common stockholders in the computation of basic and diluted earnings per share.

Table of Contents
The following table sets forth the outstanding potentially dilutive securities that have been excluded in the calculation of diluted net loss per share because their effect was anti-dilutive:

Series E Convertible Preferred Stock 1,342,250 2,684,607

Recently Adopted Accounting Pronouncement

In May 2021, the FASB issued ASU No. 2021-04 ("ASU 2021-04"), Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40): Issuer's Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (a consensus of the FASB Emerging Issues Task Force). The amendments in this update are effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. The Company has prospectively adopted this standard as of January 1, 2022 for periods presented after the adoption. The adoption of ASU 2021-04 did not have a material impact on the Company's financial statements.

Recent Accounting Pronouncement Not Yet Adopted

In August 2020, the FASB issued ASU No. 2020-06 ("ASU 2020-06"), Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40) ("ASU 2020-06"). ASU 2020-06 eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity's own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, ASU 2020-06 modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2021 (or December 15, 2023, for companies who meet the SEC definition of Smaller Reporting Companies), and interim periods within those fiscal years. The amendment is to be adopted through either a fully retrospective or modified retrospective method of transition. Early adoption is permitted. The Company is currently evaluating the impact of this standard on its financial statements and related disclosures.

Overview

We are a clinical-stage biotechnology company leveraging PLK1 inhibition to develop novel therapies across a range of cancers with the greatest unmet medical need. Our goal is to target tumor vulnerabilities with treatment combinations that overcome disease resistance, improve disease response to standard treatment regimens and increase overall survival. We are developing onvansertib, an oral and highly selective PLK1 inhibitor, in combination with standard-of-care chemotherapy and targeted therapeutics. Our clinical development programs incorporate tumor genomics and biomarker assays to refine assessment of patient response to treatment.

Our Drug Candidate, Onvansertib

Onvansertib, our lead compound, is a novel, highly potent, highly selective PLK1 inhibitor. PLK1, a serine/threonine kinase, has a well-understood mechanism of action within tumor cell proliferation and is overexpressed in a number of tumors (including colorectal, pancreatic, prostate, ovarian, breast and lung cancer). In particular, PLK1's activity in various phases of the cell cycle provide multiple targets for a PLK1 inhibitor to inhibit DNA repair and interrupt cell division, thereby killing tumor cells.

PLK1 inhibition has been considered an attractive target of cancer therapeutics for the last two decades, however past PLK1 drug candidates have failed to show acceptable tolerability and efficacy. We believe the attributes of onvansertib described below, as well as clinical evidence of favorable safety and efficacy, with expected on-target, easy to manage and reversible side effects, may prove beneficial in addressing clinical therapeutic needs across a variety of cancers:

•Onvansertib is highly potent and highly selective against the PLK1 enzyme (IC50= 2nM; IC50is the concentration for 50% inhibition), compared to prior PLK1 inhibitors that were pan-inhibitors of several PLK targets. Low or no
18
Table of Contents
activity of onvansertib was observed on a panel of 63 kinases (IC50>500 nM), including the PLK members PLK2 and PLK3 (IC50>10,000 nM).

•Onvansertib has a relatively short drug half-life of 24 hours, compared to a half-life of approximately 5 days for prior PLK1 inhibitors. A short half-life allows for flexible dosing and improved managing of drug concentrations to reduce dose-related toxicities.

•Onvansertib is orally bioavailable, compared to prior PLK1 inhibitors that were delivered intravenously, allowing for relative ease and flexibility of dosing.

In vitrostudies have shown synergistic effects when onvansertib was administered in combination with different cytotoxic agents including antimicrotubule agents, topoisomerase 1 inhibitors, antimetabolites, alkylating agents, proteasome inhibitors, kinase inhibitors, BCL-2 inhibitors, and androgen biosynthesis inhibitors.

In addition, in vivocombination studies have confirmed the positive results obtained in vitroand synergistic effects have been observed in xenograft models of onvansertib in combination with irinotecan, 5-fluorouracil ("5-FU"), abiraterone, PARP inhibitors, venetoclax, and paclitaxel, while additive effects in combination with cytarabine or bevacizumab have been demonstrated.

There are three ongoing clinical trials in onvansertib in combination treatment: second line treatment in patients with KRAS-mutated Metastatic Colorectal Cancer ("mCRC"), second line treatment in patients with Metastatic Pancreatic Ductal Adenocarcinoma ("mPDAC"), and in patients with Metastatic Castration-Resistant Prostate Cancer ("mCRPC") showing early signs of resistance to abiraterone.

Phase 1b/2 Clinical Trial in KRAS-mutated mCRC

TROV-054 is a Phase 1b/2 open-label multi-center clinical trial of onvansertib in combination with standard of care FOLFIRI and bevacizumab (Avastin®) for the second line treatment of patients with KRAS-mutated mCRC, which is being conducted at seven clinical trial sites across the U.S. - USC Norris Comprehensive Cancer Center, The Mayo Clinic Cancer Centers (Arizona, Minnesota, and Florida), Kansas University Medical Center, Inova Schar Cancer Institute and CARTI Cancer Center.

The primary objectives of this trial are to evaluate the Dose-Limiting Toxicities ("DLTs"), maximum tolerated dose ("MTD") and recommended Phase 2 dose ("RP2D") of onvansertib in combination with FOLFIRI and bevacizumab (Phase 1b) and to continue to assess the safety and preliminary efficacy of onvansertib in combination with FOLFIRI and bevacizumab (Phase 2).

The scientific rationale for this clinical trial is based on the two key principles of synthetic lethality and synergy, with the objective of demonstrating a proof-of-concept of clinical benefit within this phase1b/2 trial. Synthetic lethality refers to a critical vulnerability to tumor cell death by way of PLK1 inhibition within CRC tumor cells harboring KRAS mutations versus KRAS wild-type isogenic cells. Synergy occurs when the combination of two drugs results in an unexpected greater activity than an expected additive effect of the two drugs. Onvansertib in combination with two DNA-damaging agents, irinotecan, and 5-FU (two components of FOLFIRI), demonstrated synergy in colorectal cancer cell lines and both combinations have demonstrated significantly greater tumor growth inhibition than either drug alone in CRC in vivomodels. We believe this synergy occurs because PLK1 can promote the repair of DNA damage caused by chemotherapeutic agents and by inhibiting PLK1, onvansertib leaves damaged tumor cells unable to replicate.

Data we presented on January 18, 2022 provided an update of the ongoing phase 1b/2 clinical trial in KRAS-mutated metastatic colorectal cancer.

•34% (12 of 35) of patients treated per protocol at the RP2D in combination with FOLFIRI and bevacizumab achieved a Complete Response ("CR") or Partial Response ("PR") (CR: 1 patient; PR: 11 patients);

•35% (17 of 48) of patients across all dose levels achieved a CR or PR. Historically, Objective Response Rates ("ORR") of 5-13% have been reported in similar second line patient populations treated with various different drug combinations, including the standard of care chemotherapy of FOLFIRI with bevacizumab;

19
Table of Contents
•10% (5 of 48) of patients discontinued the trial to pursue potentially curative metastasis-directed therapy (surgical resection or microwave ablation);

•Median Progression-Free Survival ("mPFS") across all response-evaluable patients (n=48) is 9.4 months and has not yet been reached in those treated per protocol at the RP2D. Historically, mPFS of ~4.5-5.7 months has been reported in a similar patient population treated with standard of care chemotherapy of FOLFIRI with bevacizumab;

•The combination regimen of onvansertib plus FOLFIRI/bevacizumab is well tolerated with no major or unexpected toxicities attributed to onvansertib.

Phase 2 Clinical Trial in mPDAC

CRDF-001 is a Phase 2 open-label multi-center clinical trial of onvansertib in combination with nanoliposomal irinotecan (Onivyde®), leucovorin, and fluorouracil for second line treatment of patients with mPDAC, which is being conducted at six clinical trial sites across the U.S. - The Mayo Clinic Cancer Centers (Arizona, Minnesota, and Florida), Kansas University Medical Center, Inova Schar Cancer Institute, and the University of Nebraska Medical Center. The first patient was dosed in June 2021.

The objective of this trial is to assess the safety and preliminary efficacy of onvansertib in combination with nanoliposomal irinotecan (Onyvide®), 5-FU and leucovorin as a second-line treatment in patients with mPDAC who have failed first-line gemcitabine-based therapy. The trial is expected to enroll approximately 45 patients.

Phase 2 Clinical Trial in mCRPC

TROV-053 is a Phase 2 open-label multi-center clinical trial of onvansertib in combination with abiraterone acetate and prednisone in patients with mCRPC, which is being conducted at three clinical trial sites - Beth Israel Deaconess Medical Center, Dana-Farber Cancer Institute and Massachusetts General Hospital. This trial is now closed for enrollment.

The primary objective of this trial is to observe the effects of onvansertib in combination with abiraterone and prednisone on disease control as assessed by Prostate Specific Antigen ("PSA") decline or stabilization after 12 weeks of treatment in patients with mCRPC showing early signs of resistance to abiraterone.

The rationale for this trial is based on the Mechanism of Action ("MOA") of onvansertib and abiraterone acetate and the synergy of these two drugs when used in combination in pre-clinical experiments. Onvansertib inhibits tumor cell proliferation by inducing G2/M (mitosis) arrest and consequently cell death. The combination of onvansertib and abiraterone acetate synergistically increases mitotic arrest and cell death in prostate cancer cells and has demonstrated significantly greater tumor growth inhibition than either drug alone in vivo.

Data presented on April 8, 2022 at American Association for Cancer Research ("AACR") Annual Meeting provided evidence of the safety and efficacy of onvansertib in combination with abiraterone. Disease control increased with increasing dose density of onvansertib from 29% to 45% of patients achieving PSA stabilization and from 53% to 75% of patients with radiographic stable disease; Arm A (n=17) - onvansertib 24mg/m2days 1-5 in 21-day cycle to Arm C (n=20) - 12mg/m2days 1-14 in 21-day cycle. Median progression-free survival ("mPFS") increased with increasing onvansertib dose density from 4.1 months in Arm A to 13.2 months as of the data cut-off date in Arm C patients. Genomic analysis of ctDNA showed a correlation between alterations in two key genes of the PI3K signaling pathway-MTOR and PTEN, which appears to underly increased pathway activity, and sensitivity to onvansertib/abiraterone combination in mCRPC patients with early abiraterone resistance. The treatment regimen of onvansertib in combination with abiraterone/prednisone has been well tolerated.

Preclinical Data

On April 8, 2022 we announced the results of preclinical studies evaluating the anti-cancer activity of onvansertib in combination with the PARP inhibitor ("PARPi") olaparib in PARPi-resistant patient-derived xenograft (PDX) ovarian cancer models. The results were featured in a poster presentation at the AACR Annual Meeting.

Data showed the combination of onvansertib and olaparib providing statistically significant survival benefits compared to treatment with either agent alone in three PDX ovarian cancer models. Two of the three PDX models studied were cisplatin-

sensitive with a mutated BRCA1 gene, while the third was cisplatin-resistant with wild type BRCA1. The onvansertib-olaparib combination was also shown to be well tolerated in mice.

LIQUIDITY AND CAPITAL RESOURCES

Net cash used in operating activities for the six months ended June 30, 2022, was $16.9 million, compared to $10.2 million for the six months ended June 30, 2021. Our use of cash was primarily a result of the net loss of $21.4 million for the six months ended June 30, 2022, adjusted for non-cash items related to stock-based compensation of $2.2 million, amortization of premiums on short-term investments of $0.6 million, and release of clinical trial funding commitment of $0.1 million. The net change in our operating assets and liabilities was $1.5 million increasing cash used in operations. At our current and anticipated level of operating loss, we expect to continue to incur an operating cash outflow for the next several years.

Net cash provided by investing activities was $26.0 million primarily related to sales and maturities in excess of purchases of marketable securities during the six months ended June 30, 2022, compared to net cash used in investing activities of $130.7 million for net purchases of marketable securities during the same period in 2021.

Net cash provided in financing activities was $0 during the six months ended June 30, 2022, compared to $20.5 million of proceeds from the sale of common stock and proceeds from warrant exercises for the same period in 2021.

As of June 30, 2022, and December 31, 2021, we had working capital of $118.9 million and $139.6 million, respectively.
23
Table of Contents

We have incurred net losses since our inception and have negative operating cash flows. As of June 30, 2022, we had $122.0 million in cash, cash equivalents and short-term investments and we believe we have sufficient cash to meet our funding requirements for at least the next 12 months following the issuance date of this Quarterly Report on Form 10-Q.

Our drug development efforts are in their early stages, and we cannot make estimates of the costs or the time that our development efforts will take to complete, or the timing and amount of revenues related to the sale of our drug candidates. The risk of completion of any program is high because of the many uncertainties involved in developing new drug candidates to market, including the long duration of clinical testing, the specific performance of proposed products under stringent clinical trial protocols, extended regulatory approval and review cycles, our ability to raise additional capital, the nature and timing of research and development expenses, and competing technologies being developed by organizations with significantly greater resources.

For the foreseeable future, we expect to continue to incur losses and require additional capital to further advance our clinical trial programs and support our other operations. We cannot be certain that additional funding will be available on acceptable terms, or at all. To the extent that we can raise additional funds by issuing equity securities, our stockholders may experience additional dilution.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Not applicable.

ITEM 4. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
We have performed an evaluation under the supervision and with the participation of our management, including our principal executive officer (CEO) and principal financial officer (CFO), of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of June 30, 2022, to provide reasonable assurance that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms.

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives as specified above. Management does not expect, however, that our disclosure controls and procedures will prevent or detect all errors and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within our company have been detected.
Changes in Internal Control over Financial Reporting
There was no change in our internal control over financial reporting during the three months ended June 30, 2022, that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
