On November 2, 2020, the Company completed its IPO of 28,750,000 shares of its common stock at an offering price of $14.00 per share, of which 25,000,000 shares were sold by the Company and 3,750,000 shares were sold by selling stockholders, resulting in net proceeds to the Company of approximately $321,425, after deducting $20,125 of underwriting discounts and $8,450 of offering costs. The Company’s common stock is now listed on the Nasdaq Global Select Market under the ticker symbol “ALGM.”

Prior to the IPO, the Company had two classes of common stock, Class A common stock and Class L common stock. The Company’s Board of Directors authorized 12,500,000 shares of Class A common stock at par value of $0.01, out of which the Company issued 6,720,000 to Sanken in exchange for its previous shares of common stock. The previous single class of common stock was retired in full. The Company sold 2,880,000 shares of newly issued Class A common stock, representing a 28.8% ownership interest, to OEP for cash consideration of $291,000 (the “OEP Transaction”). The stock issuance proceeds were recorded net of $9,260 of related transaction costs. The Company’s Board of Directors authorized 1,000,000 shares of Class L common stock at a par value of $0.01.

Both Class A and Class L common stock were entitled to dividends when, and if, declared by the Board of Directors. Holders of shares of Class A common stock were entitled to a priority dividend of 8%. After holders of shares of Class A

common stock receive an annualized return on capital of 8%, distributions of the remaining value were split between holders of shares of Class A common stock and Class L common stock based on the achievement of certain return targets.

Each outstanding share of Class A common stock entitled the holder to one vote on each matter submitted to a vote of the stockholders of the Company, including the election of the Board of Directors. Holders of Class L common stock were not entitled to vote.

In the event of voluntary or involuntary liquidation, dissolution or winding-up of the Company, any amounts available for distribution by the Company were to be paid to the holders of Class A common stock and Class L common stock, as if such distribution were a dividend paid, factoring in the priorities as described above.

Upon the earliest of (i) an IPO; (ii) change of control; (iii) the date OEP and its affiliates cease to own any shares of capital stock of the Company; or (iv) at the election of the Board of Directors, any merger transaction involving the Company or its subsidiaries, each outstanding share of Class L common stock would convert into Class A common stock.

Also, in connection with the OEP Transaction, the Company granted 400,000 unvested shares of Class A common stock and 597,400 unvested shares of Class L common stock to certain Company employees. The shares of Class A common stock vest to the grantees over a service period of 60 months. However, they remain subject to the Company’s repurchase right at par value in the event that either (i) a change in control has not occurred or (ii) the Company has not consummated an IPO by the seventh anniversary of the OEP Transaction. As of March 27, 2020, the Company was not able to determine whether such a change in control or IPO was probable, and therefore, no amount of stock-based compensation was recognized for the unvested shares of Class A common stock at that time. As a result of the Company’s IPO closing on November 2, 2020, the unvested shares of Class A common stock immediately become vested and the Company recognized $40,440 of one-time stock-based compensation (400,000 shares to management at $101.10 per share) at that time.

The Class L unvested shares vested on a straight-line basis over a service period of four years. Class L unvested shares had no other vesting conditions. If an IPO occurred, 25% of the unvested awards would accelerate vesting if 25% or more of the awards are unvested at the time of the IPO. If a change in control occurs, 100% of the then unvested awards would accelerate vesting. Accordingly, based on the Company’s IPO closing on November 2, 2020, the Company accelerated the vesting of the 25% unvested awards at that time.

Prior to the IPO, the Company issued 17,203 shares of Class L common stock during the nine-month period ended December 25, 2020 with a weighted average price per share of $33.83 and issued 30,300 shares of Class L common stock during the nine-month period ended December 27, 2019 with a weighted average price per share of $26.93.

On October 2, 2020, the Company repurchased an aggregate of 1,997 shares of its Class L common stock from certain of its directors and one of its non-executive employees for an aggregate purchase price of $408 in connection with (i) in the case of such directors, the settlement of certain outstanding promissory notes issued by the Company to such directors, and (ii) in the case of such non-executive employee, to satisfy certain withholding tax obligations triggered by the vesting of such shares in accordance with the terms of the applicable award agreement.

Immediately following the pricing of the IPO on November 2, 2020, all outstanding shares of Class A common stock and Class L common stock were automatically converted into an aggregate of 166,500,000 shares of common stock (the “Common Stock Conversion”). Outstanding shares of Class A and Class L common stock were converted to common stock in the Common Stock Conversion at conversion rates of approximately 15.822 and 13.010 shares of common stock to each share of Class A and Class L common stock, respectively. As part of the Common Stock Conversion, 2,066,508 and 1,766 shares of common stock were returned to the Company for tax payments made on behalf of holders of Class A common stock and Class L common stock, respectively, in withhold to cover tax transactions. Outstanding loan amounts related to Class L common stock in the aggregate amount of $753 were extinguished on October 2, 2020.

The following table presents the respective number of shares of common stock and unvested restricted common stock issued in the Common Stock Conversion. The number of shares of common stock and unvested restricted common stock issuable are based upon the vesting provisions of the outstanding shares and reflect the shares vested and unvested at the date of conversion.


	Shares of Common Stock	Shares of Unvested Restricted Common Stock	Total Shares of Common Stock
Class A common stock	156,155,403	—	156,155,403
Class L common stock	7,816,574	459,749	8,276,323
Total	163,971,977	459,749	164,431,726

Prior to the IPO, there were 638,298 shares of Class L common stock outstanding at a weighted average price per share of $11.99. As noted in the above table, as part of the Common Stock Conversion, the Class L common stock was converted to 7,816,574 shares of common stock and 459,749 of unvested restricted common stock at weighted average prices per share of $14.00.

In connection with its IPO, the Company offered certain employees (excluding its named executive officers) who were eligible to receive cash bonuses under the Company’s LTCIP and TRIP the opportunity to elect to receive RSUs under its 2020 Omnibus Incentive Compensation Plan in lieu of cash payouts under the LTCIP and/or TRIP, through the LTCIP/TRIP Award RSU Conversion Program (the “RSU Conversion Program”). The expense related to the LTCIP and TRIP awards elected to be exchanged in the RSU Conversion Program amounted to $607 and $421, respectively. The number of RSUs granted to employees that elected to participate in the RSU Conversion Program is determined as a percentage of the employee’s target bonus under the LTCIP or TRIP, and amounted to 602,490 and 348,911 RSUs on behalf of the LTCIP and TRIP conversion, respectively, at a grant date fair value of $14.00. If an employee elected to not to participate in the RSU Conversion Program, the LTCIP or TRIP award will continue under its existing terms and conditions.

In addition to above, the Company also issued RSUs to its non-employee directors as consideration for their provision of future services. The stock-based compensation expense related to RSUs is measured based on the fair value market price of the Company’s common shares on the grant date and is recognized on a straight-line basis over the requisite service period, which coincides with the vesting period. RSUs can only be exchanged and settled for the Company’s common shares, on a one-to-one basis, upon vesting. RSUs are generally subject to forfeiture prior to the release of vesting restrictions. Included in the table below is a total amount of 54,644 RSUs issued to such non-employee directors.


	Number of Shares	Weighted-Average Grant-Date Fair Value		Weighted-Average Remaining Contractual Life (In years)	Aggregate Intrinsic Value
Outstanding - March 27, 2020	—	$	—	—	$	—
Granted	1,426,944	14.04

Canceled	(28,920)	14.00
Outstanding - December 25, 2020	1,397,648	$	14.04	1.74	$	34,648

The weighted-average grant fair value per share for RSUs granted during the nine-month period ended December 25, 2020 was $14.04, and the stock-based compensation expense related to non-vested awards not yet recorded at December 25, 2020 was $17,496, which is expected to be recognized over a weighted-average of 1.74 years. During the nine-month period ended December 25, 2020, 376 shares vested.

The Company also awards PSUs to its senior executive officers based on achievement of medium-term plans (“MTP”) approved in meetings of its Board of Directors for establishing target performances. Each award reflects a target number of shares (“Target Shares”) that may be issued to the award recipient. In fiscal year 2021, these awards are earned upon the completion of a three-year performance period ending March 31, 2023. Whether units are earned at the end of the performance period will be determined based on the achievement of certain performance objectives over the performance period. The performance objectives include achieving certain revenue improvement and cumulative EBITDA levels for the performance period, and also include a performance objective relating to relative total shareholder return (“TSR”). Depending on the results achieved during the three-year performance period, the actual number of shares that a grant recipient may receive at the end of the period ranges from —% to 200% of the Target Shares granted.
