Previous wording

To date, we have not had any products approved for sale and have not generated any revenue from product sales. Further, we do not expect to generate revenue from product sales until such time, if ever, that we are able to successfully complete the development and obtain marketing approval for one of our product candidates. We will continue to require additional capital to develop our product candidates and fund operations for the foreseeable future. We have incurred net losses in each year since inception and we expect to continue to incur net losses for the foreseeable future. Our ability to generate product revenue will depend on the successful development and eventual commercialization of one or more of our product candidates. Our net losses were $130.4 million, $133.3 million, and $36.3 million for the years ended December 31, 2023, 2022, and 2021, respectively. As of December 31, 2023, we had an accumulated deficit of $710.1 million. Substantially all of our net losses have resulted from costs incurred in connection with our research and development programs and from general and administrative costs associated with our operations. We expect our expenses will increase substantially in connection with our ongoing activities, as we:

On March 28, 2023, we committed to a plan to reduce our workforce by approximately 11% to better align our resources with our previously announced strategic prioritization of our late-stage progranulin and TREM2 immuno-neurology programs. We initiated such reduction in force impacting approximately 30 employees across the organization, effective March 29, 2023. As of December 31, 2023, we had cash, cash equivalents, and marketable securities of $548.9 million. In January 2024, we announced the closing of an underwritten public offering and the net proceeds from the offering were approximately $71.1 million. Our cash, cash equivalents and marketable securities as of December 31, 2023 plus the net proceeds from the offering total $620.0 million, which we anticipate provides runway through 2026.

Under the terms of the AbbVie Agreement, in addition to receiving the upfront payments from AbbVie, we may also be entitled to development and regulatory milestone payments, an opt-in payment for continued development of AL002, and other future payments from profit sharing or royalties after commercialization of product candidates from such program. Under the terms of the AbbVie Amendment signed in February 2023, the Company received a $17.8 million milestone payment in March 2023 for the dosing of the first patient in the LTE trial and $12.5 million payment in the second half of 2023 for the enrollment of additional patients.

In January 2025, AbbVie decided to terminate the TREM2 collaboration program, which resulted in termination of the AbbVie Agreement.

Previous wording

We expect that our revenue for the next several years will be derived primarily from the AbbVie and GSK Agreements. The balance of deferred revenue was $293.8 million as of December 31, 2023, related to the AbbVie and GSK Agreements. The deferred revenue is expected to be recognized over the research and development period of the programs through proof-of-concept for AL002 and the completion of the initial Phase 2 clinical trials for specified indications for latozinemab and AL101.

Specific program expenses include expenses associated with the development of our most advanced product candidates: latozinemab, which is being studied in a pivotal Phase 3 clinical trial, INFRONT-3, and which has an ongoing Phase 2 clinical trial; AL002, which is being studied in a Phase 2 clinical trial; and AL101, which has an ongoing Phase 2 clinical trial. We also have expenses related to the discovery and development of future product candidates and separately tracked expenses related to programs that we expect to move out of preclinical studies and into Phase 1 clinical trials. These expenses primarily relate to salaries and benefits, stock-based compensation, facility expenses, including depreciation, and lab consumables.

Previous wording

We expect our research and development expenses to increase substantially for the foreseeable future as we continue to invest in research and development activities related to developing our product candidates, as our product candidates advance into later stages of development, as we begin to conduct larger clinical trials, as we seek regulatory approvals for any product candidates that successfully complete clinical trials, and incur expenses associated with hiring additional personnel to support our research and development efforts. The process of conducting the necessary clinical research to obtain regulatory approval is costly and time-consuming, and the successful development of our product candidates is highly uncertain.

Current wording

At this time, we cannot reasonably estimate or know the nature, timing, and estimated costs of the efforts that will be necessary to complete the development of, and obtain regulatory approval for, any of our product candidates.

Collaboration revenue was $97.1 million for the year ended December 31, 2023, compared to $133.6 million for the year ended December 31, 2022. The decrease of $36.6 million was mainly due to $68.9 million of collaboration revenue recognized in the second quarter of 2022 due to changes in estimated costs to satisfy the performance obligations resulting from the termination of the AL003 program and a $27.0 million decrease in revenue recognized for the latozinemab programs. This was offset by a $30.6 million increase in revenue recognized for the AL101 programs, including a cumulative non-cash revenue adjustment due to contract modification to have

Current wording

Collaboration revenue was $100.6 million for the year ended December 31, 2024, compared to $97.1 million for the year ended December 31, 2023. The increase of $3.5 million was mainly due to a $15.9 million increase in revenue recognized for the AL002 program and a $9.8 million increase in revenue recognized for the latozinemab programs, offset by a $22.2 million decrease in revenue recognized for the AL101 programs. Revenues are recognized as the program costs are incurred by measuring actual costs incurred to date compared to the overall total expected costs to satisfy the performance obligation.

We reduced our workforce to better align our resources with our current strategic priorities and maintain our expectations with respect to our ability to fund our operations. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. We may also choose to seek additional financing opportunistically. We may seek to raise capital through public equity or debt financings, license agreements, collaborative agreements or other arrangements with other companies, asset sales, or through other sources of financing. We have an omnibus shelf registration statement on Form S-3 with the SEC, which became effective on May 1, 2023, which permits us to issue up to $400 million in common stock, other equity securities and/or debt securities. On November 7, 2023, we entered into an at-the-market sales agreement with TD Cowen pursuant to which we may offer and sell from time to time through TD Cowen up to $125,000,000 of shares of our common stock, in such share amounts as we may specify by notice to TD Cowen.

Previous wording

We recognize collaboration revenue at a point in time if control of the promised good or service has been transferred to the customer. We recognize collaboration revenue over time by measuring the progress toward complete satisfaction of the performance obligation using an input measure. In order to recognize revenue over the research and development period, we measure actual costs incurred to date compared to the overall total expected costs to satisfy the performance obligation. Revenues are recognized as the program costs are incurred. We re-evaluate the estimate of expected costs to satisfy the performance obligation each reporting period and make adjustments for any significant changes. Clinical trials are expensive and can take many years to complete, and the outcome is inherently uncertain. Changes in our forecasted costs are likely to occur over time based upon changes in clinical trial procedures set forth in protocols, changes in estimates of manufacturing costs, or feedback from regulators on the design or operation of our clinical trials. We have had changes to the overall expected costs to satisfy the performance obligations from period to period.

These companies are considered to be comparable to our business over a period equivalent to the expected term of the stock-based awards. In 2020, we began giving weight to our own historical volatility in the determination of expected volatility.
