Stockholders' Equity Note [Abstract]  
Stockholders' Equity Stockholders’ Equity AGI maintains two stock-based incentive plans: the 2012 Equity Incentive Plan (the “2012 Plan”) and the 2018 Equity Incentive Plan (the “2018 Plan”) that provide for the grant of shares in the form of incentive stock options, non-qualified stock options, restricted shares, stock appreciation rights and RSUs to employees, consultants, officers and directors. The 2012 Plan
expired on March 15, 2022, and remains in effect for outstanding grants only, and is no longer available for new grants. On March 8, 2022, we transferred the 129,009 unused shares under the 2012 Plan to the 2018 Plan.

As of July 31, 2022 and April 30, 2022, there were 1,050,591 and 812,763 shares, respectively, remaining available for future issuance under the 2018 Plan.

On July 6, 2022, the Company amended its Certificate of Incorporation, as amended, to increase the number of authorized shares of common stock the Company is authorized to issue from 40,000,000 to 60,000,000 authorized shares, which was approved at a special meeting of the Company's stockholders held on July 6, 2022.

On December 22, 2021, the Company held its Annual Meeting of Shareholders at which the shareholders voted to amend the 2018 Plan to increase the number of shares of common stock available for issuance under the 2018 Plan from 1,600,000 to 2,350,000 shares.

Preferred Stock

The Company is authorized to issue 1,000,000 shares of “blank check” preferred stock with designations, rights and preferences as may be determined from time to time by our Board of Directors. As of July 31, 2022 and April 30, 2022, we had no shares of preferred stock issued and outstanding.

Common Stock

At both July 31, 2022 and April 30, 2022, the Company was authorized to issue 60,000,000 shares of common stock, respectively.

Restricted Stock

As of both July 31, 2022 and April 30, 2022, there were no unvested shares of restricted common stock outstanding. During the three months ended July 31, 2022 and 2021, there were no new restricted stock grants, forfeitures, or expirations. There is no unrecognized compensation expense related to restricted stock as of July 31, 2022.

Restricted Stock Units
A summary of the Company’s RSU activity, granted under the 2012 and 2018 Equity Incentive Plans, during the three months ended July 31, 2022 is presented below:
Restricted Stock Units Number of Shares Weighted Average Grant Date Fair Value
Unvested balance outstanding, April 30, 2022 929,928  $ 6.12 
Granted —  — 
Forfeits (172,828) 7.65 
Vested (14,345) 0.97 
Expired —  — 
Unvested balance outstanding, July 31, 2022 742,755  $ 5.86 

On August 16, 2021, the Compensation Committee approved a 125,000 RSU grant to the Company’s newly hired Chief Financial Officer as part of his employment agreement. The grant has a grant date fair value of $725,000 based on a closing stock price of $5.80 per share. On August 12, 2021, the Compensation Committee approved individual grants of 80,000 RSUs to the Company’s Chief Operating Officer and Chief Academic Officer. The grants have a total grant date fair value of $1.0 million based on a closing stock price of $6.48 per share.

The three executive grants discussed above are under the Company’s 2018 Plan and are set to vest annually over a period of three years and are subject to continued employment as an officer of the Company on each applicable vesting date. The
amortization expense related to these grants for the three months ended July 31, 2022 was $146,817, which is included in "general and administrative expense" in the accompanying consolidated statement of operations.

On July 21, 2021, as part of a new employment agreement, the Compensation Committee approved a 125,000 RSU grant to the Company's Chief Executive Officer under the Company's 2018 Plan. The grant has a grant date fair value of $873,750 based on a closing stock price of $6.99 per share. As stipulated in the grant, vesting is subject to continued employment with the Company and will occur in full on the date the Company files with the SEC a quarterly or annual report on Forms 10-Q or 10-K, as applicable, which reflects the Company's reported net income on a GAAP basis. The Company was amortizing the expense over three years through July 2024 (the filing date of the Form 10-K for Fiscal Year 2024). At July 31, 2022, the Company assessed that the performance condition will not be met. Therefore, the amortization expense related to this grant of $242,708 was reversed. The amortization expense related to this grant for the three months ended July 31, 2021 was $72,813, which is included in general and administrative expense in the consolidated statements of operations prior to the reversal.

Of the 742,755 unvested RSUs outstanding at July 31, 2022, 162,500 remain from the February 4, 2020 executive grant. These RSUs vest four years from the grant date, if each applicable executive is still employed by the Company on the vesting date, and are subject to accelerated vesting for all RSUs if the closing price of the Company’s common stock is at least $12 for 20 consecutive trading days. On the grant date, the closing price of the Company's common stock on The Nasdaq Global Market was $9.49 per share. The amortization expense related to this grant for the three months ended July 31, 2022 was a net reversal of $34,150 due to the resignation of the Chief Nursing Officer on July 15, 2022. The amortization expense related to this grant for the three months ended July 31, 2021 was $112,155. The amortization expense is included in general and administrative expense in the consolidated statements of operations. The remaining unvested RSUs during the three months ended July 31, 2022 were granted to employees.

At July 31, 2022, total unrecognized compensation expense related to unvested RSUs is $2,635,885 and is expected to be recognized over a weighted-average period of approximately 1.37 years.
Warrants
The Company estimates the fair value of warrants utilizing the Black-Scholes pricing model, which is dependent upon several variables such as the expected term, expected volatility of the Company’s stock price over the expected term, expected risk-free interest rate over the expected term and expected dividend yield rate over the expected term. The Company believes this valuation methodology is appropriate for estimating the fair value of warrants issued which are subject to ASC Topic 718 requirements. These amounts are estimates and thus may not be reflective of actual future results, nor amounts ultimately realized by recipients of these grants. The Company recognizes expense on a straight-line basis over the vesting period of each warrant issued.

On April 22, 2022, as consideration for amending the Intercreditor Agreement, the Company issued warrants to the same two unaffiliated Lenders of the 2022 Convertible Notes, to each purchase 100,000 shares of the Company’s common stock exercisable for five years from the date of issuance at the exercise price of $1.00 per share. See Note 5. Long-term Debt, Net. The fair value of the warrants is $118,000 and is being amortized over the remaining term of the debt. The fair value of the warrants is treated as deferred financing costs, a non-current asset, in the accompanying consolidated balance sheets at July 31, 2022 and April 30, 2022. Total unamortized costs at July 31, 2022 and April 30, 2022 was $112,100 and $118,000, respectively. The Company has recognized $5,900 of amortization expense in connection with the fair value of the warrants for the three months ended July 31, 2022, which is included in "interest expense" in the accompanying consolidated statement of operations.
On August 31, 2021, the Compensation Committee approved the issuance of warrants to the Leon and Toby Cooperman Family Foundation as an extension fee in connection with the extension of the 2018 Credit Facility Agreement. The warrants allow for the purchase of 50,000 shares of the Company’s common stock and have an exercise price of $5.85. The warrants have an exercise period of five years from the August 31, 2021 issuance date and will terminate automatically and immediately upon the expiration of the exercise period. The fair value of the warrants is $137,500 and is being amortized over the 14-month line of credit period. The Company has recognized $11,167 of amortization expense in connection with the fair value of the warrants for the three months ended July 31, 2022, which is included in "interest expense" in the accompanying consolidated statement of operations.

On July 21, 2021, the Executive Committee approved the issuance of warrants to a former member of the Board of Directors for the purchase of 25,000 shares of the Company's common stock with an exercise price of $6.99 per share. The warrants have an exercise period of five years from the July 21, 2021 issuance date and vest annually over a three-year period subject to continued service on the Company's Advisory Board on each applicable vesting date. The warrants will terminate automatically and immediately upon the expiration of the exercise period. The fair value of the warrants is $84,000 and is being amortized over the three-year vesting period. The Company has recognized $7,000 of amortization expense in connection with the fair value of the warrants for the three months ending July 31, 2022, which is included in general and administrative expense in the accompanying consolidated statement of operations.
Stock Option Grants to Employees and Directors

The Company estimates the fair value of share-based compensation utilizing the Black-Scholes option pricing model, which is dependent upon several variables such as the expected option term, expected volatility of the Company’s stock price over the expected term, expected risk-free interest rate over the expected option term and expected dividend yield rate over the expected option term. The Company believes this valuation methodology is appropriate for estimating the fair value of stock options granted to employees and directors which are subject to ASC Topic 718 requirements. These amounts are estimates and thus may not be reflective of actual future results, nor amounts ultimately realized by recipients of these grants. The Company recognizes compensation on a straight-line basis over the requisite service period for each award.

The Company utilizes the simplified method to estimate the expected life for stock options granted to employees. The simplified method was used as the Company does not have sufficient historical data regarding stock option exercises. The expected volatility is based on historical volatility. The risk-free interest rate is based on the U.S. Treasury yields with terms equivalent to the expected life of the related option at the time of the grant. Dividend yield is based on historical trends. While
the Company believes these estimates are reasonable, the compensation expense recorded would increase if the expected life was increased, a higher expected volatility was used, or if the expected dividend yield increased.

There were no options granted to employees during the three months ended July 31, 2022 and 2021.
