RISK FACTORS
An investment in our common stock involves a high degree of risk. Before deciding whether to invest in our common stock, you should consider carefully the risks and uncertainties described below and under the section captioned “Risk Factors” contained in our most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q and other filings we make with the SEC from time to time, which are incorporated by reference herein in their entirety, together with other information in this prospectus, the information and documents incorporated by reference in this prospectus, and in any prospectus supplement or free writing prospectus that we authorize for use in connection with this offering. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could suffer materially. In such event, the trading price of our common stock could decline and you might lose all or part of your investment.
Risks Related to This Offering
If you purchase shares of common stock in this offering, you will suffer immediate dilution of your investment.
The shares sold in this offering, if any, will be sold from time to time at various prices. However, the expected offering price of our common stock will be substantially higher than the net tangible book value per share of our common stock. Therefore, if you purchase shares of our common stock in this offering, you will pay a price per share that substantially exceeds our net tangible book value per share after this offering. After giving effect to the sale of shares of our common stock in the aggregate amount of $100,000,000 at an assumed offering price of $10.29 per share, the last reported sale price of our common stock on The Nasdaq Global Select Market on August 20, 2021, after deducting commissions and estimated aggregate offering expenses payable by us, you will experience immediate dilution of $1.84 per share, representing the difference between our as adjusted net tangible book value per share as of June 30, 2021 after giving effect to this offering and the assumed offering price of $10.29 per share. To the extent outstanding options are exercised, you will incur further dilution. See “Dilution” in this prospectus for a more detailed illustration of the dilution you would incur if you participate in this offering.
You may experience future dilution as a result of future equity offerings.
In order to raise additional capital, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock at prices that may not be the same as the price per share in this offering. We may sell shares or other securities in any other offering at a price per share that is less than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock, or securities convertible or exchangeable into common stock, in future transactions may be higher or lower than the price per share paid by investors in this offering.
We have broad discretion over the use of our cash, cash equivalents and marketable securities, including the net proceeds we receive from this offering, and may not use them effectively.
Our management will have broad discretion in the use of our available cash, cash equivalents and marketable securities, including the net proceeds received from this offering, and could spend the proceeds in ways that do not improve our results of operations or enhance the value of our common stock. The failure by our management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business, cause the price of our common stock to decline and delay the development of our product candidates. Pending their use to fund operations, we may invest our cash, cash equivalents and marketable securities, including the net proceeds we receive in this offering, in a manner that does not produce income or that loses value.
The common stock offered hereby will be sold in “at the market offerings,” and investors who buy shares at different times will likely pay different prices.
Investors who purchase shares in this offering at different times will likely pay different prices, and accordingly may experience different levels of dilution and different outcomes in their investment results.

We will have discretion, subject to market demand and the terms of the sales agreement, to vary the timing, prices and number of shares sold in this offering. In addition, subject to the final determination by our board of directors or any restrictions we may place in any applicable placement notice, there is no minimum or maximum sales price for shares to be sold in this offering. Investors may experience a decline in the value of the shares they purchase in this offering as a result of sales made at prices lower than the prices they paid.

USE OF PROCEEDS
We may issue and sell shares of our common stock having aggregate gross sales proceeds of up to $100,000,000 from time to time (before deducting sales agent commissions and expenses). Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time.
We intend to use the net proceeds from the sale of any shares of common stock offered under this prospectus for general corporate purposes, which may include working capital and capital expenditures, expenses related to research, clinical development and commercial efforts, general and administrative expenses, and potential acquisitions of, or investments in, companies, technologies, products or assets that complement our business.
This expected use of net proceeds from this offering represents our intentions based upon our current plans and business conditions, which could change in the future as our plans and business conditions evolve. The amounts and timing of our actual use of the net proceeds may vary significantly depending on numerous factors, including the progress of our research and development efforts, the status of and results from clinical trials, any additional collaborations that we may enter into with third parties for our product candidates, and any unforeseen cash needs. As of the date of this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds to us from this offering. Accordingly, our management will have broad discretion in the timing and application of these proceeds.
Pending use of the proceeds as described above, we intend to invest the net proceeds in a variety of capital preservation investments, including short-term, investment-grade, interest-bearing, instruments, U.S. government securities and highly rated corporate debt securities.

DILUTION
If you invest in our common stock, your interest will be diluted to the extent of the difference between the price per share you pay in this offering and the net tangible book value per share of our common stock immediately after this offering.
Our net tangible book value as of June 30, 2021 was approximately $276.5 million, or $8.03 per share of common stock. Our net tangible book value is the amount of our total tangible assets less our total liabilities. Net tangible book value per share is equal to our total tangible assets, less our total liabilities, divided by the 34,453,239 shares of our common stock outstanding as of June 30, 2021.
After giving effect to an assumed sale of shares of our common stock in the aggregate amount of $100,000,000 in this offering at an assumed offering price of $10.29 per share, the last reported sale price of our common stock on The Nasdaq Global Select Market on August 20, 2021, and after deducting commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of June 30, 2021 would have been approximately $373.2 million, or $8.45 per share of common stock. This represents an immediate increase in net tangible book value of $0.42 per share to our existing stockholders and an immediate dilution of $1.84 per share to new investors in this offering. The following table illustrates this calculation on a per share basis.
Assumed offering price per share
$ 10.29
Net tangible book value per share as of June 30, 2021
$ 8.03
Increase in net tangible book value per share attributable to new investors purchasing shares in this offering
$ 0.42
As adjusted net tangible book value per share after giving effect to this offering
$ 8.45
Dilution per share to new investors in this offering
$ 1.84
The as adjusted information is illustrative only and will adjust based on the actual offering price, the actual number of shares sold and other terms of the offering determined at the time shares of our common stock are sold pursuant to this prospectus. The as adjusted information assumes that all of our common stock in the aggregate amount of $100,000,000 is sold at the assumed offering price of $10.29 per share, the last reported sale price of our common stock on The Nasdaq Global Select Market on August 20, 2021. The shares sold in this offering, if any, will be sold from time to time at various prices.
The table and discussion above are based on the 34,453,239 shares of common stock outstanding as of June 30, 2021, which includes 21,609 shares of unvested restricted stock subject to repurchase by us, and excludes:

4,579,286 shares of common stock issuable upon exercise of stock options outstanding as of June 30, 2021, at a weighted-average exercise price of $12.05 per share;

4,542,522 shares of common stock reserved as of June 30, 2021 for future issuance under our 2020 Stock Incentive Plan, as well as any automatic increases in the number of shares of common stock reserved under this plan; and

704,488 shares of common stock reserved as of June 30, 2021 for future issuance under our 2020 Employee Stock Purchase Plan, as well as any automatic increases in the number of shares of common stock reserved under this plan.

PLAN OF DISTRIBUTION
We entered into the sales agreement with Cowen on August 13, 2021, under which we may issue and sell from time to time up to an aggregate of $100.0 million of our common stock through Cowen as our sales agent. Sales of our common stock, if any, will be made at market prices by any method that is deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act, including sales made directly on the Nasdaq Global Select Market or any other trading market for our common stock. A copy of the sales agreement that we entered into with Cowen is filed with the SEC as an exhibit to the registration statement of which this prospectus is a part.
Cowen will offer our common stock subject to the terms and conditions of the sales agreement on a daily basis or as otherwise agreed upon by us and Cowen. We will designate the maximum amount of common stock to be sold through Cowen on a daily basis or otherwise determine such maximum amount together with Cowen. Subject to the terms and conditions of the sales agreement, Cowen will use its commercially reasonable efforts to sell on our behalf all of the shares of common stock requested to be sold by us. We may instruct Cowen not to sell common stock if the sales cannot be effected at or above the price designated by us in any such instruction. Cowen or we may suspend the offering of our common stock being made through Cowen under the sales agreement upon proper notice to the other party. Cowen and we each have the right, by giving written notice as specified in the sales agreement, to terminate the sales agreement in each party’s sole discretion at any time.
The aggregate compensation payable to Cowen as sales agent will be equal to 3.0% of the gross sales price of the shares sold through it pursuant to the sales agreement. We have also agreed to reimburse Cowen for up to $50,000 of Cowen’s actual outside legal expenses incurred by Cowen in connection with this offering, and for certain other expenses. We estimate that the total expenses of the offering payable by us, excluding commissions payable to Cowen under the sales agreement, will be approximately $300,000.
The remaining sales proceeds, after deducting any expenses payable by us and any transaction fees imposed by any governmental, regulatory, or self-regulatory organization in connection with the sales, will equal our net proceeds for the sale of such common stock.
Cowen will provide written confirmation to us following the close of trading on the Nasdaq Global Select Market on each day in which common stock is sold through it as sales agent under the sales agreement. Each confirmation will include the number of shares of common stock sold through it as sales agent on that day, the volume weighted average price of the shares sold, the percentage of the daily trading volume and the net proceeds to us.
We will report at least quarterly the number of shares of common stock sold through Cowen under the sales agreement, the net proceeds to us and the compensation paid by us to Cowen in connection with the sales of common stock.
Settlement for sales of common stock will occur, unless the parties agree otherwise, on the second business day that is also a trading day following the date on which any sales were made in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.
In connection with the sales of our common stock on our behalf, Cowen will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to Cowen will be deemed to be underwriting commissions or discounts. We have agreed in the sales agreement to provide indemnification and contribution to Cowen against certain liabilities, including liabilities under the Securities Act. As sales agent, Cowen will not engage in any transactions that stabilize our common stock.
Our common stock is listed on the Nasdaq Global Select Market and trades under the symbol “AKUS.” The transfer agent of our common stock is Computershare Trust Company, N.A.
Cowen and/or its affiliates have provided, and may in the future provide, various investment banking and other financial services for us for which services they have received and, may in the future receive, customary fees.
