Based on the available objective evidence at this time, management believes that it is more-likely-than-not that the net deferred tax assets of the Company will not be realized. Accordingly, management has applied a full valuation allowance against net deferred tax assets at both  December 31, 2023 and December 31, 2022. The net valuation allowance increased by approximately $4.8 million during the year ended  December 31, 2023. The increase in net valuation allowance primarily relates to net operating losses generated during 2023.

 

At December 31, 2023, the Company has Federal and California net operating loss carryforwards of approximately $171.4 million and $4.1 million, respectively, which will begin to expire on December 31, 2034 for Federal and California purposes. Approximately $146.2 million of federal net operating losses were generated after December 31, 2017 and thus do not expire. Approximately $25.2 million of the federal net operating losses and $4.1 million state net operating loss carryforwards will begin to expire in December 31, 2034, if not utilized.

 

Utilization of the Company’s net operating loss may be subject to substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state provisions. Such an annual limitation could result in the expiration of net operating loss carryforwards prior to utilization.

 

At  December 31, 2023, the Company had research and development credits carryforward of approximately $0.5 million and $0.5 million for Federal and California income tax purposes, respectively. If not utilized, the Federal research and development credits carryforward will begin to expire on  December 31, 2034. The California credits can be carried forward indefinitely.

 

The Company’s policy is to account for interest and penalties as income tax expense. As of  December 31, 2023, the Company had no interest related to unrecognized tax benefits. No amounts of penalties related to unrecognized tax benefits were recognized in the provision for income taxes.

 

Effective January 1, 2022, the Company is subject to mandatory capitalization of Section 174 research and development expenditures. The capitalized expenditures are subject to amortization over five years for expenses incurred within the U.S. The Company capitalized $3.6 million and $3.6 million during the years ended December 31, 2023 and December 31, 2022, respectively.

 

The Company maintains liabilities for uncertain tax positions. These liabilities involve considerable judgement and estimation and are continuously monitored by management based on the best information available, including changes in tax regulations, the outcome of relevant court cases, and other information. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits as income tax expense. At  December 31, 2023, the Company’s total amount of unrecognized tax benefit was approximately $0.5 million, none of which will affect the effective tax rate, if recognized. The Company does not expect its unrecognized benefits to change materially over the next twelve months.

 

The Company files income tax returns with the United States federal government and the State of California. The Company’s tax returns for 2020 to 2022 remain open to audit for Federal and California purposes.
