Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Landos Biopharma Australia Pty Ltd. All intercompany balances and transactions have been eliminated in consolidation.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company’s audited financial statements and notes thereto included in its Annual Report on Form 10-K for the year ended December 31, 2022. In the opinion of the Company’s management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of its financial position, operating results and cash flows for the periods presented have been included. Operating results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the full year, for any other interim period or for any future year.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts in the Company's consolidated financial statements and the disclosures made in the accompanying notes. Significant estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not limited to, accrued liabilities, fair value of equity instruments and uncertain tax positions. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Despite management’s intention to establish accurate estimates and use reasonable assumptions, actual results may differ from the Company's estimates.

Significant Accounting Policies

The significant accounting policies used in preparation of these unaudited condensed consolidated financial statements for the three and six months ended June 30, 2023 are consistent with, and should be read in conjunction with, those discussed in Note 1 of the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and highly liquid investments with original maturities of three months or less at the date of purchase. The carrying amounts approximate fair value due to the short maturities of these investments. Cash equivalents consist primarily of amounts invested in money market funds and are stated at fair value.

Marketable Securities

The Company’s investments in marketable securities are maintained by investment managers and consist of corporate debt securities and asset backed securities with original maturities of over 90 days, all of which are considered available-for-sale debt securities. The Company classifies its available-for-sale securities as short-term marketable securities on the Condensed Consolidated Balance Sheets, even though the stated maturity date may be one year or more beyond the current Condensed Consolidated Balance Sheets date, as the Company views those securities as available for use in current operations, if needed.

Available-for-sale securities are carried at fair value with their unrealized gains and losses included in accumulated other comprehensive loss within stockholders’ equity, until such gains and losses are realized in other income, net, within the Condensed Consolidated Statements of Operations and Comprehensive Loss, except for the changes in allowance for expected credit losses, which are recorded in other income, net, within the Condensed Consolidated Statements of Operations and Comprehensive Loss. Realized gains and losses are determined using the specific identification method.

The Company conducts periodic reviews to identify and evaluate each investment in its portfolio that has an unrealized loss to determine whether a credit loss exists. An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis.

A credit loss is estimated by considering available information relevant to the collectability of the security and information about past events, current conditions and reasonable and supportable forecasts. Any credit loss is recorded as a charge to other income, net, not to exceed the amount of the unrealized loss. Unrealized losses other than the credit loss are recognized in accumulated other comprehensive loss. When determining whether a credit loss exists, the Company considers several factors, including whether the Company has the intent to sell the security or whether it is more likely than not that the Company will be required to sell the security prior to recovery of its amortized cost basis. If the Company has an intent to sell, or if it is more likely than not that the Company will be required to sell a debt security in an unrealized loss position before recovery of its amortized cost basis, the Company will write down the security to its fair value and record the corresponding charge as a component of other income, net. No declines in value were deemed to be credit losses as of January 1, 2023, the adoption date of Accounting Standards Update (“ASU”) 2016-13—Financial Instruments (Topic 326) Measurement of Credit Losses on Financial Instrument (“ASU 2016-23”), or during the three and six months ended June 30, 2023.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash, cash equivalents and marketable securities. Bank deposits are held by accredited financial institutions, and these deposits are often in excess of insured limits. The Company limits its credit risk associated with cash and cash equivalents by placing them with financial institutions it believes are of high quality.

The Company’s available-for-sale investments primarily consist of high-grade corporate debt securities and asset-backed securities and potentially subject the Company to concentrations of credit risk. The Company has adopted investment guidelines that limit the amounts the Company may invest in any one type of investment and requires all investments held by the Company to be highly rated, thereby reducing credit risk exposure.

Research and Development Expenses

Research and development costs consist primarily of external costs related to clinical development, contract manufacturing and discovery as well as personnel costs. The Company estimates preclinical and clinical study and research expenses based on the services performed, pursuant to contracts with research institutions that conduct and manage nonclinical and clinical studies and research services on its behalf. The Company records the costs of research and development activities based upon the estimated amount of services provided but not yet invoiced and includes these costs in accrued liabilities in the Condensed Consolidated Balance Sheets. These costs are a component of the Company’s research and development expenses. The Company accrues for these costs based on factors such as estimates of the work completed and in accordance with agreements established with its third-party service providers under the service agreements. The Company makes significant judgments and estimates in determining the accrued liabilities balance in each reporting period. As actual costs become known, the Company adjusts its accrued liabilities.

Government Assistance Tax Credits

The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) provided refundable employee retention credits ("ERC"), which are used to offset payroll tax liabilities. During the three months ending June 30, 2023, the Company determined that it qualified for an ERC in the amount of $0.6 million related to labor costs recognized during 2020 and 2021 and filed its amended employment tax returns to claim this credit. The entire amount of $0.6 million is included in prepaid expenses and other current assets in the Company's Condensed Consolidated Balance Sheet as of June 30, 2023. The Company has recorded $0.4 million of the offset of this receivable as a reduction to research and development expense and $0.2 million as a reduction to general and administrative expense in the accompanying Condensed Consolidated Statement of Operations and Comprehensive Loss for the three months ended June 30, 2023. In August 2023, prior to the filing of this Quarterly Report on Form 10-Q, the Company has received all $0.6 million of refunds.

Net Loss per Share

Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock together with the number of additional shares of common stock that would have been outstanding if all potentially dilutive shares of common stock had been issued. The Company included the weighted-average number of pre-funded warrants issued in its private placement in the number of outstanding shares for calculating basic and diluted net loss per share because the shares issuable upon exercise of the pre-funded warrants will be issued for little to no consideration. The following table sets forth the computation of basic and diluted net loss per share during the periods presented (in thousands, except share and per share amounts):


	Three Months Ended June 30,						Six Months Ended June 30,
	2023			2022			2023			2022
Numerator:
Net loss	$	(3,922	)	$	(11,284	)	$	(9,956	)	$	(26,148	)
Denominator:
Weighted-average shares of common stock issued and outstanding		3,116,798			4,025,489			3,407,989			4,025,489
Weighted-average pre-funded warrants outstanding		3,090,909			—			2,937,217			—
Weighted-average shares used to calculate net loss per common share, basic and diluted		6,207,707			4,025,489			6,345,206			4,025,489
Net loss per common stock, basic and diluted	$	(0.63	)	$	(2.80	)	$	(1.57	)	$	(6.50	)

The following outstanding shares of potentially dilutive securities have been excluded from diluted net loss per common share for the periods presented, because their inclusion would be anti-dilutive:


	Six Months Ended June 30,
	2023		2022
Stock options to purchase common stock		494,716		365,417
Restricted stock units		99,807		—
Total		594,523		365,417

Comprehensive Loss

The Company’s comprehensive loss is currently comprised of changes in unrealized loss on available-for-sale securities.

Segment Reporting

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker in making decisions regarding resource allocation and assessing performance. The Company views its operations and manages its business in one operating segment.

Emerging Growth Company Status

The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an EGC or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-23, which requires an allowance for expected credit losses on financial assets be recognized as early as day one of the instrument. This ASU departs from the incurred loss model which means the probability threshold is removed. It considers more forward-looking information and requires the entity to estimate its credit losses as far as it can reasonably estimate. The ASU was effective for fiscal years beginning after December 15, 2019 for public business entities that are U.S. Securities and Exchange Commission (“SEC”) filers, excluding entities eligible to be smaller reporting companies (“SRC”). For all other public business entities, including SRC, the ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company's adoption of ASU 2016-13 as of January 1, 2023 did not have a material impact on the condensed consolidated financial statements and accompanying notes.
