Societal CDMO, Inc.

Series A Convertible Preferred Stock

This is a public offering of convertible preferred stock, or the Series A preferred stock, of Societal CDMO, Inc. We are offering 450,000 shares of our Series A preferred stock.

There is no established trading market for the Series A preferred stock, and we do not expect a market to develop. In addition, we do not intend to list the Series A preferred stock on the Nasdaq Capital Market, any other national securities exchange or any other nationally recognized trading system. Without an active trading market, the liquidity of the Series A preferred stock will be limited.

Our common stock is listed on the Nasdaq Capital Market under the symbol “SCTL.” On December 9, 2022, the last reported sale price of our common stock on the Nasdaq Capital Market was $1.27 per share.

Subject to our shareholders approving an amendment to our Second Amended and Restated Articles of Incorporation, as amended, to increase the number of shares of common stock we are authorized to issue, each share of Series A preferred stock is convertible into 10 shares of our common stock automatically upon such approval without any further action or the payment of additional consideration by the holder thereof. If such shareholder approval is not obtained by June 30, 2023, the then-in-effect conversion rate of the Series A preferred stock shall be increased by 10% and will increase by an additional 10% per year on June 30 of each year for which shareholder approval has not yet been obtained, subject to certain limits. In the event of our liquidation, dissolution or winding up, holders of our Series A preferred stock will be entitled to be paid out of our assets available for distribution to our shareholders before any proceeds are distributed to the holders of our common stock.

Shares of Series A preferred stock will generally have no voting rights, except as required by law and except that the consent of holders of a majority of the outstanding Series A preferred stock will be required to amend the terms of the Series A preferred stock or take certain other actions with respect to the Series A preferred stock.

Concurrently with this offering, and pursuant to a separate prospectus supplement, we are also conducting a public offering, or the Concurrent Offering, of 27,841,737 shares of our common stock.

Investing in our securities involves a high degree of risk. See “Risk Factors ” beginning on page S-10 of this prospectus supplement and in the documents incorporated by reference in this prospectus supplement.

PROSPECTUS SUPPLEMENT SUMMARY

This summary is not complete and does not contain all the information you should consider before investing in our securities pursuant to this prospectus supplement and the accompanying prospectus. Before investing in our securities, you should carefully read this entire prospectus, including the information incorporated by reference herein, especially the matters discussed in the information set forth under the sections titled “Risk Factors” in this prospectus supplement, the accompanying prospectus and in the documents incorporated by reference into this prospectus supplement.

Overview

We are a bi-coastal contract development and manufacturing organization, or CDMO, with capabilities spanning pre-investigational new drug development to commercial manufacturing and packaging for a wide range of therapeutic dosage forms with a primary focus in the area of small molecules. With an expertise in solving complex formulation and manufacturing problems, we are a leading CDMO providing development, end-to-end regulatory support, clinical and commercial manufacturing, aseptic fill/finish, lyophilization, packaging and logistics services to the global pharmaceutical market. In addition to our experience in handling DEA controlled substances and developing and manufacturing advanced dosage forms, we have the expertise to deliver on our clients’ pharmaceutical development and manufacturing projects, regardless of complexity level. We do all of this in our best-in-class facilities that, in the aggregate, total 145,000 square feet, in Gainesville, Georgia and San Diego, California.

We currently manufacture the following key products with our key commercial partners: Ritalin LA, Focalin XR, Verelan PM, Verelan SR, Verapamil PM, Verapamil SR and Donnatal liquids and tablets, as well as support numerous development stage products.

Effective March 21, 2022, we changed our name to Societal CDMO, Inc. to reflect the corporate transformation that has taken place primarily as a result of our acquisition and successful integration of IriSys into our organization.

We use cash flow generated by our business primarily to fund the growth of our CDMO business and to make payments under our credit facility. We believe our business will continue to contribute cash to fund our growth, to make payments under our credit facility and for other general corporate purposes.

Recent Developments

Purchase and Sale Agreement and Lease Agreement

On December 9, 2022, our wholly owned subsidiary, Societal CDMO Gainesville, LLC, or Societal Gainesville, entered into a purchase and sale agreement, or the Purchase Agreement, with Tenet Equity Funding SPE Gainesville, LLC, or the Purchaser, a subsidiary of Tenet Equity L.P., pursuant to which Societal Gainesville agreed to sell certain real estate located at 1300 Gould Drive, Gainesville, Georgia 30504, or the Property, to the Purchaser for a purchase price of $39.0 million. We collectively refer to the transactions contemplated thereby as the “Sale-Leaseback Transaction.”

The closing of the Sale-Leaseback Transaction is conditioned on, among other things, the outstanding principal amount of the term loans under the Athyrium Credit Agreement (as defined below) being reduced to $40 million or less (after the application of the proceeds from the Sale-Leaseback Transaction).

S-4

Pursuant to the terms of the Purchase Agreement, upon the closing of the Sale-Leaseback Transaction, Societal Gainesville and the Purchaser will enter into a lease agreement, or the Lease, pursuant to which Societal Gainesville will lease the Property from the Purchaser for an initial term of 20 years, with four renewal options of 10 years each. The total annual base rent under the Lease will be approximately $3.5 million per year and will increase (i) on the first anniversary of the effective date of the Lease, by the greater of (A) 3% and (B) the change in the consumer price index, not to exceed 5%; and (ii) thereafter, on each successive anniversary of the effective date of the Lease, at a rate of 3%. Societal Gainesville will also be responsible for payment of all operating expenses, property taxes and insurance for the Property. Pursuant to the terms of the Lease, Societal Gainesville will have a purchase option every 10 years and a right of first offer and a right of first refusal to purchase the Property should the Purchaser intend to sell the Property to a third party.

Seventh Amendment to Athyrium Credit Agreement

On December 9, 2022, we entered into a Seventh Amendment to Credit Agreement, or the Amendment, with the Guarantors (defined below), the Lenders (defined below), and Athyrium Opportunities III Acquisition LP, or Athyrium Opportunities III, in its capacity as administrative agent. The Amendment further amends that certain Credit Agreement, dated as of November 17, 2017 (as amended from time to time, the “Athyrium Credit Agreement”), by and among us, our subsidiaries named as guarantors therein, or the Guarantors, the lenders party thereto, or the Lenders, and Athyrium Opportunities III.

The Amendment provides, among other things: (i) Athyrium Opportunities III’s and the Lenders’ required consent regarding the Sale-Leaseback Transaction; (ii) for certain amendments to the Athyrium Credit Agreement, including an adjustment to the amount and timing of the required principal amortization payments, made in conjunction with the Sale-Leaseback Transaction; and (iii) for a prepayment of principal the terms loan made under the Athyrium Credit Agreement in an aggregate amount equal to the $60 million in aggregate principal amount (plus accrued and unpaid interest and the required exit fee).

RBC Credit Agreement

On December 12, 2022 we entered into a Credit Agreement with our subsidiaries named as guarantors therein, Royal Bank of Canada, who is also acting as the underwriter in this offering and the Concurrent Offering, in its capacity as administrative agent, or RBC, and the lenders named therein, or the RBC Credit Agreement. The RBC Credit Agreement provides for a term loan, or the Term A Loan, in the original principal amount of up to $37.5 million to be funded on the closing date thereof, or the RBC Credit Agreement Closing, which is expected to occur before the end of 2022 upon the satisfaction of the closing conditions set forth in the RBC Credit Agreement. The maturity date, or the Maturity Date, of the Term A Loan under the RBC Credit Agreement is the three-year anniversary of the RBC Credit Agreement Closing.

The RBC Credit Agreement Closing and funding thereunder is contingent on certain closing conditions, including the completion of the Sale-Leaseback Transaction, a minimum $32.5 million equity financing being raised by us, and full repayment of all existing debt facilities, including the term loans under the Athyrium Credit Agreement. The original principal amount of the Term A Loan shall be adjusted lower on a dollar for dollar basis to the extent such equity financing is greater than $32.5 million; provided that such original principal amount shall be not be less than $35 million.

The Term A Loan will bear interest at a floating rate equal to the three-month term Secured Overnight Financing Rate, or SOFR, with an initial floor of 1%, plus an applicable margin that is equal to 4.50% per annum for the first year following the RBC Credit Agreement Closing and increases to 5.00% for the second year following the RBC Credit Agreement Closing and 5.50% for the third year following the RBC Credit Agreement Closing and thereafter, with quarterly interest payments due and owing until the Maturity Date. The outstanding principal amount of the Term A Loan will be repaid in quarterly amortization payments (subject to the Asset Paydown (defined below)), commencing with the quarter ending March 31, 2023, in an amount equal to (i) 1.25% of the original principal amount for all quarterly principal payments made through December 31, 2023; (ii) 1.875% of the

S-5

original principal amount for all quarterly principal payments due for the quarter ending March 31, 2024 through the quarter ending December 31, 2024; (iii) 2.50% of the original principal amount for all quarterly principal payments due for the quarter ending March 31, 2025 until the Maturity Date; and (iv) all outstanding principal amount of the Term A Loan shall be deemed to be $10 million less than the fully funded amount for purposes of calculating amortization payments upon the occurrence of the Asset Paydown (as defined below) if it occurs within 12 months from the funding date of the Term A Loan. The remaining principal amount of Term A Loan is due and payable on the Maturity Date.

Subject to certain exceptions, we are required to make mandatory prepayments of the Term A Loan with the cash proceeds received in respect of asset sales, extraordinary receipts and debt issuances, upon a change of control and specified other events. Additionally, we are obligated to repay $10 million of principal, or the Asset Paydown, within 12 months of the RBC Credit Agreement Closing upon the sale of certain real property located at 1300 Gould Drive, Gainesville, Georgia 30504. If such real property is not sold within the first 12 months of the RBC Credit Agreement Closing, (i) the amortization percentages referenced above will increase by an additional 0.625% for each installment due until such time as such real property is sold and the Asset Paydown is made and (ii) we will be required to pay, ratably to the Lenders as of the date 12 months after the funding of the RBC Credit Agreement, a fee equal to 1.00% of the original principal balance of Term A Loan funded on the funding date.

We may make voluntary principal prepayments in whole or in part, provided that such prepayments are in minimum amounts of $1 million and in whole multiples of $250,000 in excess thereof. Such prepayments will not be subject to any prepayment fee or penalty outside of any compensation required to be paid to lenders on account of any actual loss or expense related to liquidation or reemployment of deposits or other funds required for the lender to maintain term SOFR loans (which shall not include compensation for loss of anticipated profits).

We expect to use the proceeds from the Term A Loan, this offering, and the Concurrent Offering, to repay in full all outstanding indebtedness under the Athyrium Credit Agreement and terminate such agreement, which had provided us with $100 million in term loans due on December 31, 2023, at an interest rate equal to the three-month LIBOR rate, with a 1% floor plus 8.25% per annum.

At September 30, 2022, we reported unamortized deferred issuance costs of $5.7 million related to the Athyrium Credit Agreement. We expect there will be a non-cash write-off of this balance in the fourth quarter of 2022 as a result of us entering into the RBC Credit Agreement, in addition to certain other fees and expenses, which we plan to present in the aggregate as a loss on extinguishment of debt within the consolidated statement of operations.

The RBC Credit Agreement contains representations and warranties and affirmative and negative covenants customary for financings of this type as well as customary events of default. Certain of the customary negative covenants limit our ability and certain of our subsidiaries, among other things, to incur debt, grant liens, make investments, make acquisitions, make certain restricted payments and sell assets, subject to certain exceptions. In addition, the RBC Credit Agreement requires that we comply with a minimum liquidity covenant that is measured as of the end of each fiscal quarter and requires at least $4 million of liquidity through September 30, 2023 (which amount increases to $4.5 million and $5 million in subsequent periods). The RBC Credit Agreement also includes a maximum leverage ratio beginning at 3.75:1.00 and stepping down to 2.75:1.00 and a minimum fixed charge ratio of 1.15:1.00, with both covenants being measured as of the end of each fiscal quarter.

Concurrent Offering of Shares of Common Stock

Concurrently with this offering, we are conducting a public offering of 27,841,737 shares of our common stock, which we refer to as the Concurrent Offering. The Concurrent Offering is being conducted as a separate public offering by means of a separate prospectus supplement. This offering is not contingent upon the completion of the Concurrent Offering and the Concurrent Offering is not contingent upon the completion of this offering.

S-6

We cannot assure you that either or both of the offerings will be completed. Additionally, the Sale-Leaseback Transaction is conditioned on, among other things, the outstanding principal amount of the term loan under the Athyrium Credit Agreement being reduced to $40 million or less, and we cannot assure you that we will be able to meet this condition absent the completion of this offering and the Concurrent Offering. Furthermore, the funding of the RBC Credit Agreement is contingent on the completion of the Sale-Leaseback Transaction, a minimum $32.5 million equity financing being raised by us, and full repayment of all existing debt facilities, including the term loans under the Athyrium Credit Agreement.

Pending their use, we may invest the net proceeds from this offering and the Concurrent Offering in short-term, investment-grade, interest-bearing securities. These investments may not yield a favorable return to our shareholders. Our failure to apply these funds effectively could harm our business, delay the development of our pipeline product candidates and cause the price of our common stock to decline.

If you purchase the Series A preferred stock sold in this offering, and assuming its conversion into shares of our common stock, you will experience immediate and substantial dilution in the net tangible book value per share of the common stock.

Since the price per share of the common stock issuable upon the conversion of the Series A preferred stock being offered is substantially higher than the net tangible book value per share of our common stock, you will suffer immediate and substantial dilution in the net tangible book value of the common stock you purchase in this offering. Based on a public offering price of $11.00 per share, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us, and based on a net tangible book value (deficit) of our common stock of $(0.16) per share as of September 30, 2022, if you purchase shares of Series A preferred stock in this offering, you will suffer immediate dilution of $1.18 per share in the net tangible book value of common stock. See “Dilution” for a more detailed discussion of the dilution you will incur if you purchase shares of common stock in this offering.

Our shareholders will experience additional dilution upon the issuance of common stock being offered pursuant to the Concurrent Offering of our common stock.

The issuance of shares of our common stock being offered pursuant to the Concurrent Offering will be dilutive to the outstanding shares of common stock. Any dilution or potential dilution may cause our shareholders to sell their shares, which would contribute to a downward movement in the price of our common stock.

S-10

Future issuances of shares of common stock or securities convertible into or exercisable for shares of common stock following this offering, as well as the exercise of options and warrants outstanding, will further dilute your ownership interests and may adversely affect the future market price of our common stock.

We expect that significant additional capital will be needed in the future to continue our planned operations. We may seek additional capital through a combination of private and public equity offerings, debt financings, strategic partnerships and alliances and licensing arrangements, which may cause your ownership interest to be diluted. In addition, we have a significant number of options and warrants to purchase shares of our common stock outstanding. If these securities are exercised, you may incur further dilution. Moreover, to the extent that we issue additional options or warrants to purchase, or securities convertible into or exchangeable for, shares of our common stock in the future and those options, warrants or other securities are exercised, converted or exchanged, shareholders may experience further dilution.

A substantial number of shares may be sold in the market following this offering, which may depress the market price for our common stock.

Sales of a substantial number of shares of our common stock in the public market following this offering could cause the market price of our common stock to decline. Immediately after this offering and the Concurrent Offering, we will have 84,521,126 outstanding shares of common stock, based on the number of shares our common stock outstanding as of September 30, 2022. This includes the shares that we are selling in this offering, which may be resold in the public market immediately without restriction, unless purchased by our affiliates or certain of our existing shareholders. In addition, we have also registered the shares of common stock that we may issue under our equity incentive plans. As a result, these shares can be freely sold in the public market upon issuance, subject to restrictions under securities laws.

The market price and trading volume of our common stock have been and may continue to be volatile.

The market price for our common stock has been volatile and may continue to fluctuate or may decline significantly in the future. An active, liquid and orderly market for our common stock may not be sustained, which could depress the trading price of our common stock or cause it to continue to be highly volatile or subject to wide fluctuations. As a result of this volatility, you may not be able to sell your common stock at or above the public offering price and you may lose some or all of your investment. Some of the factors that could negatively affect our share price or result in fluctuations in the price or trading volume of our common stock include, among other things:

•

our ability to consummate the transactions contemplated by the Sale-Leaseback Transaction and the RBC Credit Agreement;

•

our expectations related to the use of proceeds from this offering and the Concurrent Offering;

•

the successful completion of this offering and the Concurrent Offering;

•

FDA, state or international regulatory actions, including actions on regulatory applications for any of our commercial partners’ product candidates;

•

Noncompliance with applicable state, federal, and international data privacy and security laws and regulations including, without limitation, the General Data Protection Regulation (Regulation (EU) 2016/679), as amended, and the California Consumer Privacy Act of 2018, as amended;

•

legislative or regulatory changes;

•

judicial pronouncements interpreting laws and regulations;

•

changes in government programs;

S-11

•

announcements of new products, services or technologies, commercial relationships, acquisitions or other events by us or our competitors;

•

changes in demand for or pricing of our customers’ products;

•

the sales ramp and trajectory for our formulation, development and manufacturing services;

•

market conditions in the pharmaceutical and biotechnology sectors;

•

fluctuations in stock market prices and trading volumes of similar companies;

•

changes in accounting principles;

•

litigation or public concern about the safety of our products or similar products;

•

sales of large blocks of our common stock, including sales by our executive officers, directors and significant shareholders;

•

our announcement of financing transactions, including debt, convertible notes, etc.; and

•

actions by institutional or activist shareholders.

These broad market and industry factors may decrease the market price of our common stock, regardless of our actual operating performance. In addition, in the past, following periods of volatility in the overall market and decreases in the market price of a company’s securities, securities class action litigation has often been instituted against these companies. Any such litigation could result in substantial costs and a diversion of our management’s attention and resources.

There is no public market for the Series A preferred stock being offered by us in this offering.

There is no established public trading market for the Series A preferred stock being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the Series A preferred stock on any national securities exchange or other nationally recognized trading system, including the Nasdaq Capital Market. Without an active market, the liquidity of the Series A preferred stock will be limited.

If you purchase Series A preferred stock sold in this offering, you will not be able to convert the Series A preferred stock to common stock until after the proposal to amend our Articles of Incorporation to increase the number of authorized shares of common stock is approved by the requisite vote of our shareholders.

The Series A preferred stock will only be convertible into common stock upon receipt of shareholder approval of an increase in the number of authorized shares of our common stock. While we intend to use commercially reasonable efforts to obtain the requisite approval from our shareholders, we can offer no assurance that we will ever be able to obtain such approval. If the increase in the number of authorized shares of common stock is not approved by our shareholders, the Series A preferred stock may never become convertible.

Risks Related to the Sale-Leaseback Transaction and the RBC Credit Agreement

Our ability to complete the Sale-Leaseback Transaction and close on the RBC Credit Agreement is subject to several closing conditions and the receipt of consents and approvals from third parties, which may impose conditions that could adversely affect us or cause the contemplated transactions not to be completed.

The completion of the Sale-Leaseback Transaction is subject to a number of closing conditions as specified in the Purchase Agreement entered into with the Purchaser. These include, among others, the outstanding principal amount of the term loans under the Athyrium Credit Agreement being reduced to $40 million or less (after the application of the proceeds from the Sale-Leaseback Transaction). Although we have (i) reached an agreement with Royal Bank of Canada to refinance a portion of the term loans under the Athyrium Credit Agreement; (ii) reached an agreement with Athyrium to provide their consent to the Sale-Leaseback Transaction; and

S-12

(iii) intend to proceed with this offering, no assurance can be given that we will be successful with regard to those matters, and that all of the closing conditions under the Purchase Agreement will be satisfied in a timely manner or at all. Any delay in completing the Sale-Leaseback Transaction could cause us not to realize, or to be delayed in realizing, some or all of the benefits that we expect to achieve. In addition, we can provide no assurance that these conditions will not result in the abandonment or delay of the Sale-Leaseback Transaction, the RBC Credit Agreement, or this offering.

Similarly, the closing and funding of the Term A Loan under the RBC Credit Agreement is subject to a number of closing conditions as specified in the RBC Credit Agreement entered into with the Royal Bank of Canada. These include, among others, (i) the completion of an equity financing by us resulting in net proceeds of no less than $32.5 million, (ii) the completion of the Sale-Leaseback Transaction, and (iii) full repayment of all existing debt facilities, including the term loans under the Athyrium Credit Agreement. Although we have reached an agreement with the Purchaser regarding the Sale-Leaseback Transaction and we intend to proceed with this offering, no assurance can be given that all of the required consents and approvals will be obtained or that the closing conditions under the RBC Credit Agreement will be satisfied in a timely manner or at all. Any delay in closing on the RBC Credit Agreement and receiving the proceeds from the Term A Loan could cause us not to realize, or to be delayed in realizing, some or all of the benefits that we expect to achieve. In addition, we can provide no assurance that these conditions will not result in the abandonment or delay of the Sale-Leaseback Transaction, the RBC Credit Agreement, or this offering.

The occurrence of any one of these events could have a material adverse effect on our results of operations, cash flows, financial condition and/or the trading price of our common stock.

S-13

USE OF PROCEEDS

We estimate that the net proceeds to us from this offering, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, will be approximately $4.5 million.

In addition, we estimate that the net proceeds to us from the Concurrent Offering will be approximately $28.3 million after deducting underwriting discounts and commissions and estimated offering expenses payable by us. This offering is not contingent upon the completion of the Concurrent Offering, and the Concurrent Offering is not contingent upon the completion of this offering.

We expect to use the net proceeds from this offering and the Concurrent Offering to repay $25.8 million of the $100 million outstanding principal amount of the term loans under the Athyrium Credit Agreement. The term loans under the Athyrium Credit Agreement bear a rate of interest equal to the three-month LIBOR rate, with a 1% floor plus 8.25% per annum, and mature on December 31, 2023.

We intend to use the net proceeds from this offering and the Concurrent Offering for the repayment of our outstanding debt facility with Athyrium Opportunities III and associated costs to satisfy closing conditions for a capital structure refinancing, including the Sale-Leaseback Transaction in connection with our facility in Gainesville, Georgia, and the Term A Loan debt facility with Royal Bank of Canada. We intend to use the net proceeds from this offering and the Concurrent Offering, together with proceeds from the new Term A Loan and the Sale-Leaseback Transaction, to repay in full and retire the outstanding debt facility with Athyrium Opportunities III, with any remaining proceeds to be used for general corporate and working capital purposes.

Pending use of the proceeds from this offering and the Concurrent Offering as described above, we intend to invest the net proceeds of this offering in money market funds, certificates of deposit and corporate debt securities.

S-14

DIVIDEND POLICY

We have never declared or paid any cash dividends on our common stock and our ability to pay cash dividends is currently prohibited by the terms of our credit facility with Athyrium III. We do not anticipate paying cash dividends on our common stock in the foreseeable future. Payment of future dividends, if any, on our common stock will be at the discretion of our board of directors after taking into account various factors, including our financial condition, operating results, anticipated cash needs and plans for expansion.

S-15

DILUTION

Our net tangible book value (deficit) as of September 30, 2022 was $(9.0) million, or $(0.16) per share of common stock based upon 56,679,389 shares outstanding. Net tangible book value per share is equal to our total tangible assets less our total liabilities, divided by the total number of shares of common stock outstanding as of September 30, 2022.

After giving effect to our issuance and sale of 450,000 shares of our Series A preferred stock in this offering at the public offering price per share of Series A preferred stock of $11.00 , assuming the conversion of all shares of our Series A preferred stock sold in this offering into 4,500,000 shares of our common stock, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us, our net tangible book value as of September 30, 2022 would have been $(4.9) million, or $(0.08) per share. This represents an immediate increase in net tangible book value of $0.08 per share to existing shareholders and an immediate dilution in net tangible book value of $1.18 per share of common stock to investors participating in this offering.

The following table illustrates this dilution on a per share basis:


Public offering price per share of common stock into which the shares of Series A preferred stock being offered as part of this offering are convertible				$	1.10
Net tangible book value (deficit) per share of common stock as of September 30, 2022.	$	(0.16	)
Increase in net tangible book value per share of common stock attributable to new investors in this offering	$	0.08
As adjusted net tangible book value				$	(0.08	)
Dilution per share to new investors in this offering				$	1.18

The foregoing table and calculations are based on 56,679,389 shares of our common stock outstanding as of September 30, 2022 and excludes:

•

8,116,892 shares of our common stock issuable upon the exercise of stock options outstanding as of September 30, 2022 at a weighted-average exercise price of $3.88 per share;

•

2,145,666 shares of our common stock issuable upon the vesting and settlement of restricted stock units outstanding as of September 30, 2022;

•

288,667 shares of our common stock available for future issuance as of September 30, 2022 under our Amended and Restated Equity Incentive Plan; and

•

348,664 shares of our common stock issuable upon the exercise of outstanding warrants as of September 30, 2022 with a weighted average exercise price of $1.73 per share.

The above discussion and table do not take into account giving effect to the shares of common stock offered by us in the Concurrent Offering. Giving effect to both this offering and the Concurrent Offering at the public offering price per share of common stock of $1.10 (assuming conversion of all shares of Series A preferred stock offered in this offering), our as adjusted net tangible book value as of September 30, 2022, would have been approximately $21.3 million, or $0.24 per share of common stock, which represents an immediate increase in net tangible book value of $0.40 per share of common stock to existing shareholders and immediate dilution in net tangible book value of $0.86 per share of common stock into which the shares of Series A preferred stock are convertible to investors participating in this offering.

Unless otherwise indicated, all information in this prospectus supplement assumes no exercise of the outstanding options and warrants or settlement of the restricted stock units described above.

S-16

To the extent that outstanding options and warrants are exercised, you will experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our shareholders.

S-17

DESCRIPTION OF SECURITIES WE ARE OFFERING

We are offering 450,000 shares of our Series A preferred stock. We are also registering the shares of common stock issuable from time to time upon conversion of the Series A preferred stock offered hereby.

The following description of our capital stock and provisions of our Second Amended and Restated Articles of Incorporation, as amended, or our Articles of Incorporation, Third Amended and Restated Bylaws, or our Bylaws, and the Pennsylvania Business Corporation Law of 1988, as amended, or the PBCL, are summaries and are qualified in their entirety by reference to our Articles of Incorporation and our Bylaws. We have filed copies of these documents with the SEC as exhibits to the registration statement of which this prospectus supplement and the accompanying prospectus form a part.

Authorized Capital Stock

Pursuant to our Articles of Incorporation, our authorized capital stock consists of 95,000,000 shares of common stock, par value of $0.01 per share, and 10,000,000 shares of preferred stock, par value $0.01 per share, to be designated from time to time by our board of directors.

Common Stock

As of September 30, 2022, there were 56,679,389 shares of our common stock issued and outstanding. Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of shareholders, including the election of directors, and do not have cumulative voting rights. Accordingly, the holders of a majority of the outstanding shares of common stock in person or represented by proxies in any election of directors can elect all of the directors standing for election, if they so choose, other than any directors that holders of any preferred stock that we may issue may be entitled to elect.

Subject to preferences that may be applicable to any then-outstanding shares of preferred stock, holders of our common stock are entitled to receive ratably dividends when, as, and if declared by our board of directors out of funds legally available therefor, subject to any preferential dividend rights of outstanding preferred stock. In the event of our liquidation, dissolution, or winding up, holders of our common stock will be entitled to ratably receive the net assets of our company available after the payments of all debts and other liabilities and subject to the prior rights of the holders of any then-outstanding shares of preferred stock.

Holders of our common stock have no preemptive, subscription, redemption or conversion rights. All outstanding shares of our common stock are, and the common stock to be outstanding upon completion of this offering will be, duly authorized, validly issued, fully paid and non-assessable. The rights and privileges of the holders of the common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

Series A Preferred Stock

The following summary of certain terms and provisions of our Series A preferred stock offered in this offering is subject to, and qualified in its entirety by reference to, the terms and provisions set forth in our certificate of designation of preferences, rights and limitations of Series A preferred stock, or the Certificate of Designations, that we expect to file as an exhibit to a Current Report on Form 8-K.

General. Our Articles of Incorporation authorizes our board of directors to issue up to 10,000,000 shares of our preferred stock, par value $0.01 per share.

Subject to the limitations prescribed by our Articles of Incorporation, our board of directors is authorized to establish the number of shares constituting each series of preferred stock and to fix the designations, powers,

S-18

preferences and rights of the shares of each of those series and the qualifications, limitations and restrictions of each of those series, all without any further vote or action by our shareholders. Our board of directors has designated 450,000 of the 10,000,000 authorized shares of preferred stock as Series A preferred stock. When issued, the shares of Series A preferred stock will be validly issued, fully paid and non-assessable.

Automatic Conversion Upon Authorized Share Approval. Each share of our Series A preferred stock will automatically convert into 10 shares of our common stock without any further action or the payment of additional consideration by the holder thereof, subject to and immediately upon, approval by our shareholders of an amendment to our Second Amended and Restated Articles of Incorporation, as amended, and filing and effectiveness thereof, to increase the number of shares of common stock we are authorized to issue, which we refer to as Authorized Share Approval. We have agreed to use commercially reasonable efforts to obtain Authorized Share Approval. The number of shares of common stock issuable upon conversion of each share of Series A preferred stock is determined by multiplying one share of Series A preferred stock by the Series A Conversion Rate in effect at the time of conversion. The “Series A Conversion Rate” shall initially be 10 shares of common stock for each share of Series A preferred stock. The Series A Conversion Rate shall be subject to adjustment as provided in the Certificate of Designation. If Authorized Share Approval is not obtained by June 30, 2023, the Series A Conversion Rate then-in-effect shall be increased by 10% and will increase by an additional 10% per year on June 30 of each year for which the Authorized Share Approval has not yet been obtained, subject to the limits set forth in the Certificate of Designation.

Liquidation Preference. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company, the holders of shares of Series A preferred stock then outstanding shall be entitled to be paid out of the assets of the Company available for distribution to our shareholders, and in the event of a Deemed Liquidation Event (as defined in the Certificate of Designations) the holders of shares of Series A preferred stock then outstanding shall be entitled to be paid out of the consideration payable to shareholders in such Deemed Liquidation Event or out of the Available Proceeds (as defined in the Certificate of Designations), as applicable, before any payment shall be made to the holders of common stock by reason of their ownership thereof, an amount per share, or the Series A Liquidation Amount, equal to the greater of (i) the Series A Original Issue Price, plus any dividends declared but unpaid thereon, or (ii) such amount per share as would have been payable had all shares of Series A preferred stock been converted into common stock pursuant to the Certificate of Designations immediately prior to such liquidation, dissolution, winding up or Deemed Liquidation Event. The Series A Original Issue Price shall mean $11.00 per share, subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Series A preferred stock.

Voting Rights. The Series A preferred stock is non-voting stock and does not entitle the holder thereof to vote on any matter submitted our shareholders for their action or consideration, except as otherwise provided by the PBCL or the other provisions of the Articles of Incorporation or the Certificate of Designations.

As long as any shares of Series A preferred stock are outstanding, we may not, without the approval of the holders of a majority of the outstanding shares of Series A preferred stock, take the following actions: (i) amend, alter or repeal any provision of the Articles of Incorporation, the Certificate of Designations or Bylaws of the Company in a manner that adversely affects the powers, preferences or rights of the Series A preferred stock; (ii) create, or authorize the creation of, or issue or obligate itself to issue shares of, any additional class or series of capital stock unless the same ranks junior to the Series A preferred stock with respect to the distribution of assets on the liquidation, dissolution or winding up of the Company, the payment of dividends and rights of redemption, or increase the authorized number of shares of Series A preferred stock or increase the authorized number of shares of any additional class or series of capital stock of the Company unless the same ranks junior to the Series A preferred stock with respect to the distribution of assets on the liquidation, dissolution or winding up of the Company, the payment of dividends and rights of redemption; (iii) (A) reclassify, alter or amend any

S-19

existing security of the Company that is pari passu with the Series A preferred stock in respect of the distribution of assets on the liquidation, dissolution or winding up of the Company, the payment of dividends or rights of redemption, if such reclassification, alteration or amendment would render such other security senior to the Series A preferred stock in respect of any such right, preference, or privilege or (B) reclassify, alter or amend any existing security of the Company that is junior to the Series A preferred stock in respect of the distribution of assets on the liquidation, dissolution or winding up of the Company, the payment of dividends or rights of redemption, if such reclassification, alteration or amendment would render such other security senior to or pari passu with the Series A preferred stock in respect of any such right, preference or privilege; or (iv) purchase or redeem (or permit any subsidiary to purchase or redeem) or pay or declare any dividend or make any distribution on, any shares of capital stock of the Company (with exceptions for dividends on the common stock solely in the form of additional shares of common stock).

Dividends. Holders of Series A preferred stock shall be entitled to receive dividends or distributions on shares of Series A preferred stock equal (on an as-if-converted-to-common stock basis) to and in the same form as dividends or distributions actually paid on shares of our common stock when, as and if such dividends or distributions are paid on shares of our common stock. No other dividends or distributions shall be paid on shares of Series A preferred stock.

Exchange Listing. We do not intend to list the Series A preferred stock on the Nasdaq Capital Market, any other national securities exchange or any other nationally recognized trading system. We expect the common stock issuable upon conversion of the Series A preferred stock to be listed on the Nasdaq Capital Market.

Listing

Our common stock is listed on the Nasdaq Capital Market under the symbol “SCTL.”

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Broadridge Corporate Issuer Solutions, Inc.

Anti-Takeover Provisions of Pennsylvania Law, our Articles of Incorporation, and our Bylaws

Pennsylvania Anti-Takeover Law

Provisions of the PBCL applicable to us provide, among other things, that:

•

we may not engage in a business combination with an “interested shareholder,” generally defined as a holder of 20% of a corporation’s voting stock, during the five-year period after the interested shareholder became such except under certain specified circumstances;

•

holders of our common stock may object to a “control transaction” involving us (a control transaction is defined as the acquisition by a person or group of persons acting in concert of at least 20% of the outstanding voting stock of a corporation), and demand that they be paid a cash payment for the “fair value” of their shares from the “controlling person or group”;

•

holders of “control shares” will not be entitled to voting rights with respect to any shares in excess of specified thresholds, including 20% voting control, until the voting rights associated with such shares are restored by the affirmative vote of a majority of disinterested shares and the outstanding voting shares of the Company; and

•

any “profit,” as defined, realized by any person or group who is or was a “controlling person or group” with respect to us from the disposition of any equity securities of within 18 months after the person or group became a “controlling person or group” shall belong to and be recoverable by us.

S-20

Pennsylvania-chartered corporations may exempt themselves from these and other anti-takeover provisions. Our Articles of Incorporation do not provide for exemption from the applicability of these or other anti-takeover provisions in the PBCL.

The provisions noted above may have the effect of discouraging a future takeover attempt that is not approved by our board of directors but which individual shareholders may consider to be in their best interests or in which shareholders may receive a substantial premium for their shares over the then current market price. As a result, shareholders who might wish to participate in such a transaction may not have an opportunity to do so. The provisions may make the removal of our board of directors or management more difficult. Furthermore, such provisions could result our company being deemed less attractive to a potential acquiror and/or could result in our shareholders receiving a lesser amount of consideration for their shares of our common stock than otherwise could have been available either in the market generally and/or in a takeover.

Articles of Incorporation and Bylaws

Provisions of our Articles of Incorporation and Bylaws may delay or discourage transactions involving an actual or potential change of control or change in our management, including transactions in which shareholders might otherwise receive a premium for their shares, or transactions that our shareholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock. Among other things, our Articles of Incorporation and Bylaws:

•

divide our board of directors into three classes with staggered three-year terms;

•

provide that a special meeting of shareholders may be called only by a majority of our board of directors;

•

establish advance notice procedures with respect to shareholder proposals to be brought before a shareholder meeting and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a committee of the board of directors;

•

provide that shareholders may only act at a duly organized meeting; and

•

provide that members of our board of directors may be removed from office by our shareholders only for cause by the affirmative vote of 75% of the total voting power of all shares entitled to vote generally in the election of directors.

Our Bylaws also provide that, unless we consent in writing to the selection of an alternative forum, a state or federal court located within the County of Chester in the Commonwealth of Pennsylvania will be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of our company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees or our shareholders, (iii) any action asserting a claim arising pursuant to any provision of the PBCL, or (iv) any action asserting a claim peculiar to the relationships among or between our company and our officers, directors and shareholders. When there are no federal courts located in the County of Chester, as is currently the case, the exclusive forum provision of our Bylaws establishes exclusive jurisdiction for the matters above in the state courts of the County of Chester. However, such provision does not establish exclusive jurisdiction in the state courts of the County of Chester for claims that arise under the Securities Act, the Exchange Act or other federal securities laws if there is exclusive or concurrent jurisdiction in the federal courts.

Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge their credit exposure to us consistent with their customary risk management policies. A typical such hedging strategy would include these underwriters or their affiliates hedging such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

As discussed further elsewhere in this prospectus supplement, Royal Bank of Canada is acting as administrative agent under the RBC Credit Agreement. See “Prospectus Supplement Summary - Recent Developments - RBC Credit Agreement” for more information.

ABOUT THIS PROSPECTUS

This prospectus provides you only with a general description of the securities that we may offer. Each time that we or the selling shareholders offer and sell securities, we or the selling shareholders will provide a prospectus supplement to this prospectus that contains specific information about the securities being offered and sold and the specific terms of that offering. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to these offerings. The prospectus supplement or free writing prospectus may also add, update or change information contained in this prospectus with respect to that offering. If there is any inconsistency between the information in this prospectus and the applicable prospectus supplement or free writing prospectus, you should rely on the prospectus supplement or free writing prospectus, as applicable. Before purchasing any securities, you should carefully read both this prospectus and the applicable prospectus supplement (and any applicable free writing prospectuses), together with the additional information described under the heading “Where You Can Find More Information.”

We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We will not make an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus and the applicable prospectus supplement to this prospectus is accurate only as of the date on its respective cover, that the information appearing in any applicable free writing prospectus is accurate only as of the date of that free writing prospectus, and that any information incorporated by reference is accurate only as of the date of the document incorporated by reference, unless we indicate otherwise. Our business, financial condition, results of operations and prospects may have changed since those dates.

When we refer to “Recro,” “we,” “our,” “us” and the “Company” in this prospectus, we mean Recro Pharma, Inc., and its consolidated subsidiaries unless otherwise specified. References to the “selling shareholders” refer to the shareholders listed herein under the heading “Selling Shareholders” and their respective pledgees, donees, permitted transferees, assignees, successors and others who later come to hold any of the selling shareholders’ interests in our securities other than through a public sale.

ABOUT RECRO

Overview

We are a dedicated contract development and manufacturing organization, or CDMO, solving complex formulation and manufacturing challenges for companies developing oral solid dose drug products. We leverage our formulation and development expertise to develop and manufacture pharmaceutical products using proprietary delivery technologies and know-how for partners who develop and commercialize or plan to commercialize these products. In 2020, we launched our clinical trials support services capabilities, which includes preparation of clinical trial supplies, as well as specialized services dedicated to the development and Good Manufacturing Practices, or GMP, of high-potency products. We operate a 97,000 square foot, DEA-licensed manufacturing facility in Gainesville, Georgia, as well as a 24,000 square foot development, high-potency product and clinical packaging facility in Gainesville, Georgia that we opened in October 2018. We currently develop and/or manufacture the following key products with our key commercial partners: Ritalin LA^®, Focalin XR^®, Verelan PM^®, Verelan SR^®, Verapamil PM and Verapamil SR, as well as supporting development stage products.

Our manufacturing and development capabilities include formulation, product development from formulation through clinical trial and commercial manufacturing, and specialized capabilities for solid oral dosage forms, extended release and controlled substance manufacturing, as well as high potency development and manufacturing. In a typical collaboration, we work with our partners to develop product candidates, or new formulations of existing product candidates, and may license certain intellectual property to such partners. We also typically exclusively manufacture and supply clinical and commercial supplies of these proprietary products and product candidates.

Our Strategy

The CDMO market is large and growing and is expected to continue to expand as outsourced penetration is seen due to biotechnology and pharmaceutical companies outsourcing more of their operations. We believe companies, which include our customers and prospective customers, generally prefer fewer, higher quality suppliers with specialized expertise in addressing their formulation and manufacturing challenges early in the development cycle. Our strategy for growth in this market includes:

•

Expand Existing Customer Relationships. We maintain strong customer relationships with large pharmaceutical and biotechnology companies with established and stable pharmaceutical products. Our development-stage business also provides us the opportunity to provide services through the lifecycle of a product. Approximately 90% of our development customers have signed additional proposals for extension work, such as next step development proposals or additional batches. We view this repeat work as indicative of the level of confidence our existing customers have in our technical ability and reliable execution. We believe this pattern indicates potential for future growth and plan to leverage our current relationships for new business opportunities moving forward.

•

Diversify Our Customer Base. We have taken, and continue to take, steps to diversify and expand our customer base. Over the last several years, we have increased our focus on business development, hired subject matter experts and established additional systems and processes to expand our offering of development-stage services to attract new customers. In 2020 we launched new clinical trial support services, or CTS, capabilities, and we launched a significant new commercial product tech transfer project. This strategy has resulted in adding 16 new customers over the past two years, and we expect to further expand our business with new customers in 2021.

•

Invest in our Manufacturing Capabilities. We intend to continue investing in our facilities and infrastructure to maximize our utilization and support our customers’ development and commercial manufacturing requirements.

•

Explore Acquisitions and Licensing. We may drive growth through the acquisition of business capabilities, products, product lines, technologies and capabilities.

Our Competitive Strengths

We believe that the strong relationships we have with our commercial partners result from of our competitive strengths. In particular:

•

Our Operational Excellence. We maintain a commitment to continually improve productivity and customer service levels and maintain excellent quality and regulatory compliance systems.

•

Focus on Specialized Markets. We participate in specialized markets where significant technical expertise provides a competitive advantage. This includes differentiated drug delivery, controlled substance and complex formulation. Our core expertise is modified release oral solid dosage form development and manufacturing and custom release profile development, including for DEA controlled substance products. We developed extended, controlled and sustained release mechanisms and other intellectual property for several current commercial products.

•

Our Longstanding Relationships with Our Partners. We maintain longstanding, collaborative relationships with our customers. We believe this allows us to leverage our extensive experience and deep knowledge of their business to better address our commercial partners’ business and developmental goals.

•

Our Integrated Full-Service Development and Manufacturing Facilities. We believe pharmaceutical companies generally prefer to engage with CDMOs that are able to work with a product throughout its lifecycle and have experienced a reliable track record of regulatory compliance and quality control first-hand. Our early-stage development and high-potency business feeds clinical and commercial manufacturing opportunities to our manufacturing business. We believe that by providing customers with a broad range of services from benchtop through commercial launch and supply, we can best support the needs of our customers throughout the lifecycle of their products. We provide fully-integrated and customized biomanufacturing services that support our customers from the early preclinical stage through commercial launch and supply. Our services are all supported by modern facilities designed to meet customer needs from early stage development to commercial supply.

•

Our Customer-Centric, Consultative Approach. We are highly collaborative throughout the product lifecycle, guiding our commercial partners through the development process towards commercialization, including support and guidance on regulatory matters and chemistry, manufacturing and controls, or CMC, regulatory document preparation. In particular, we provide differentiated capabilities across a broad array of services that support the ability to serve our commercial partners through the entire development spectrum.

Services

We offer integrated solutions for formulation, analytical services, regulatory support, manufacturing, and packaging of both commercial and development stage oral solid dose drug products. Our two facilities are located just four miles apart in Gainesville, Georgia, allowing employees to seamlessly move from one facility to the other and leveraging the same support staff for facilities, quality, project management and information technology:

•

Our 97,000 square foot manufacturing facility provides a full range of manufacturing capabilities from scale-up services to commercial manufacture.

•

Our 24,000 square foot development and high-potency product facility focuses on development and clinical packaging.

-2-

Our end-to-end service capabilities allow our customers to start with us for early-phase projects and stay with us through late phase and commercial projects. Early-stage coordination with customers utilizing our development and high-potency product facility helps assure streamlined technology transfer for final scale up and manufacturing at our commercial manufacturing site.

RISK FACTORS

Investing in any securities offered pursuant to this prospectus and any applicable prospectus supplement involves risks. You should carefully consider the risk factors included in our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K we file after the date of this prospectus, together with any amendments or supplements thereto, and all other information contained or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in the applicable prospectus supplement and any applicable free writing prospectus before acquiring any of our securities. The occurrence of any of these risks might cause you to lose all or part of your investment in the offered securities. Additional risks not known to us or that we believe are immaterial may also significantly impair our business operations and could result in a loss of all or part of your investment in the offered securities.

Risks Related to the Common Stock Offered by the Selling Shareholders

If the selling shareholders sell significant amounts of our common stock, or the perception exists that these sales could occur, such events could cause our common stock price to decline.

This prospectus covers the resale from time to time by the selling shareholders of up to 2,202,420 shares of our common stock. Once the registration statement, of which this prospectus is a part, is declared effective, all of these shares will be available for resale in the public market. If the selling shareholders sell significant amounts of our common stock following the effectiveness of the registration statement of which this prospectus is a part, the market price of our common stock could decline. Further, the perception of these sales or issuances could impair our ability to raise additional capital through the sale of our equity securities.

None of the proceeds from the sale of shares of our common stock by the selling shareholders in this offering will be available to us.

We will not receive any proceeds from the sale of shares of our common stock by the selling shareholders in this offering. The selling shareholders will receive all proceeds from the sale of such shares. Consequently, none of the proceeds from such sale by the selling shareholders will be available to us for our use. See “Use of Proceeds.”

-4-

USE OF PROCEEDS

Except as set forth in any accompanying prospectus supplement, we intend to use the net proceeds from the sale of any securities offered under this prospectus for general corporate purposes unless the applicable prospectus supplement provides otherwise. General corporate purposes may include, and are not limited to, working capital, repayment of debt (including debt service, principal and interest), acquisitions or investments in businesses and capital expenditures.

We may temporarily invest the net proceeds in a variety of capital preservation instruments, including investment grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government, or may hold such proceeds as cash, until they are used for their stated purpose. We have not determined the amount of net proceeds to be used specifically for such purposes. As a result, management will retain broad discretion over the allocation of net proceeds.

We will not receive any proceeds from the sale of shares of our common stock by the selling shareholders.

Common Stock

Authorized Capital Stock. Our authorized capital stock consists of (i) 50,000,000 shares of common stock, par value $0.01 per share, of which 31,012,003 shares have been issued and are outstanding as of February 19, 2021, referred to as the capitalization date, and (ii) 10,000,000 shares of preferred stock, par value $0.01 per share, of which no shares have been issued and are outstanding as of the capitalization date. We do not hold any shares of our capital stock in its treasury.

Preferred Stock

Our board of directors has the authority, without further action by our shareholders, to issue up to 10,000,000 shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each such series, to fix the dividend, voting and other rights, preferences and privileges of the shares of each wholly unissued series and any qualifications, limitations or restrictions thereon, and to increase or decrease the number of shares of any such series, but not below the number of shares of such series then outstanding. Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in our control and may adversely affect the market price of the common stock and the voting and other rights of the holders of our common stock.

Anti-Takeover Effects of Our Amended and Restated Articles of Incorporation and Our Amended and Restated Bylaws

Provisions of our amended and restated articles of incorporation and amended and restated bylaws may delay or discourage transactions involving an actual or potential change of control or change in our management, including transactions in which shareholders might otherwise receive a premium for their shares, or transactions that our shareholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock. Among other things, our amended and restated articles of incorporation and amended and restated bylaws:

•

Divide our board of directors into three classes with staggered three-year terms;

•

Provide that a special meeting of shareholders may only be called only by a majority of our board of directors, the chairman of our board of directors, the chief executive officer or the president;

•

Establish advance notice procedures with respect to shareholder proposals to be brought before a shareholder meeting and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a committee of the board of directors;

•

Provide that shareholders may only act at a duly organized meeting;

•

Provide that certain provisions of the amended and restated articles of incorporation may only be amended with the affirmative vote of 66 2/3% of the holders of the outstanding shares of capital stock; and

•

Provide that members of our board of directors may be removed from office by our shareholders only for cause by the affirmative vote of 75% of the total voting power of all shares entitled to vote generally in the election of directors.

Our amended and restated articles of incorporation also provide that, unless we consent in writing to the selection of an alternative forum, a state or federal court located within the County of Philadelphia in the Commonwealth of Pennsylvania will be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of our company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees or our shareholders, (iii) any action asserting a claim arising pursuant to any provision of the Pennsylvania Business Corporation Law, or the PBCL, or (iv) any action asserting a claim peculiar to the relationships among or between our company and our officers, directors and shareholders.

The exclusive forum provision described above is intended to apply to the fullest extent permitted by law, including to actions arising under the Securities Act or the Exchange Act. However, the enforceability of exclusive forum provisions in the governing documents of other companies has been challenged in legal proceedings, and it is possible that a court could find our forum selection provision to be inapplicable or unenforceable with respect to actions arising under the Securities Act or the Exchange Act. Even if it is accepted that our exclusive forum provision applies to actions arising under the Securities Act, shareholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder.

Anti-Takeover Provisions under Pennsylvania Law

Pennsylvania Anti-Takeover Law

Provisions of the PBCL applicable to us provide, among other things, that:

•

-7-

outstanding voting stock of a corporation), and demand that they be paid a cash payment for the “fair value” of their shares from the “controlling person or group;”

•

Pennsylvania-chartered corporations may exempt themselves from these and other anti-takeover provisions. Our amended and restated articles of incorporation do not provide for exemption from the applicability of these or other anti-takeover provisions in the PBCL.

Our bylaws also provide that, unless we consent in writing to the selection of an alternative forum, a state or federal court located within the County of Chester in the Commonwealth of Pennsylvania will be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of our company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees or our shareholders, (iii) any action asserting a claim arising pursuant to any provision of the PBCL, or (iv) any action asserting a claim peculiar to the relationships among or between our company and our officers, directors and shareholders. When there are no federal courts located in the County of Chester, as is currently the case, the exclusive forum provision of our bylaws establishes exclusive jurisdiction for the matters above in the state courts of the County of Chester. However, such provision does not establish exclusive jurisdiction in the state courts of the County of Chester for claims that arise under the Securities Act, the Exchange Act or other federal securities laws if there is exclusive or concurrent jurisdiction in the federal courts.

Transfer and Exchange

Each debt security will be represented by either one or more global securities registered in the name of The Depository Trust Company, or the Depositary, or a nominee of the Depositary (we will refer to any debt security represented by a global debt security as a book-entry debt security), or a certificate issued in definitive registered form (we will refer to any debt security represented by a certificated security as a certificated debt security) as set forth in the applicable prospectus supplement. Except as set forth under the heading “Global Debt Securities and Book-Entry System” below, book-entry debt securities will not be issuable in certificated form.

Certificated Debt Securities

You may transfer or exchange certificated debt securities in accordance with the terms of the indenture. You will not be charged a service charge for any transfer or exchange of certificated debt securities but may be required to pay an amount sufficient to cover any tax or other governmental charge payable in connection with such transfer or exchange.

You may effect the transfer of certificated debt securities and the right to receive the principal of, premium and interest on certificated debt securities only by surrendering the certificate representing those certificated debt securities and either reissuance by us or the trustee of the certificate to the new holder or the issuance by us or the trustee of a new certificate to the new holder.

Each global debt security representing book-entry debt securities will be deposited with, or on behalf of, the Depositary, and registered in the name of the Depositary or a nominee of the Depositary. Please see “Global Securities.”

No Protection in the Event of a Change of Control

Unless we state otherwise in the applicable prospectus supplement, the debt securities will not contain any provisions which may afford holders of the debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control) which could adversely affect holders of debt securities.

Covenants

Unless otherwise indicated in this prospectus or the applicable prospectus supplement, our debt securities may not have the benefit of any covenant that limits or restricts our business or operations, the pledging of our assets or the incurrence by us of indebtedness. We will describe in the applicable prospectus supplement any material covenants in respect of a series of debt securities.

-11-

Consolidation, Merger and Sale of Assets

We may not consolidate with or merge with or into, or sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of our properties and assets to any person, or a successor person, unless:

•

the indenture shall remain in full force and effect and either we are the surviving corporation or the successor person (if other than us) is a corporation organized and validly existing under the laws of any U.S. domestic jurisdiction or a corporation or comparable legal entity organized under the laws of a foreign jurisdiction and expressly assumes by a supplemental indenture executed and delivered to the trustee, all of our obligations on the debt securities and under the indenture; and

•

immediately after giving effect to the transaction, no Default or Event of Default, shall have occurred and be continuing.

Defaults and Notice

Unless otherwise specified in the resolution of our board of directors, supplemental indenture or officer’s certificate establishing a series of debt securities, “Event of Default” means with respect to any series of debt securities, any of the following:

•

failure to pay the principal of, or premium, if any, on any debt security when the same becomes due and payable at Maturity, upon acceleration, redemption or otherwise;

•

failure to make a payment of any interest on any debt security of such series when due and payable, and the default continues for a period of 30 days;

•

failure to perform or observe any other covenants or agreements in the indenture with respect to the debt securities of the series or in the Indenture for 60 days after written notice from the trustee or the holders of not less than 25% of the aggregate principal amount of the debt securities of the series then outstanding, with such notice specifying the default, demanding that it be remedied and stating that the notice is a “Notice of Default”;

•

certain events relating to our bankruptcy, insolvency or reorganization or the bankruptcy, insolvency or reorganization of a Significant Subsidiary;

•

certain cross defaults, if and as applicable; and

•

any other Event of Default specified in the resolution of our board of directors, supplemental indenture or officer’s certificate establishing such series of debt securities.

No Event of Default with respect to a particular series of debt securities necessarily constitutes an Event of Default with respect to any other series of debt securities. The occurrence of certain Events of Default or an acceleration under the indenture may constitute an event of default under certain indebtedness of ours or our subsidiary outstanding from time to time.

If an Event of Default with respect to debt securities of any series at the time outstanding (except as to certain events of bankruptcy, insolvency or reorganization) occurs and is continuing, then the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal of, and accrued and unpaid interest, if any, on, all debt securities of that series. In the case of an Event of Default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding debt securities will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of outstanding debt securities. At any time after a declaration of acceleration with respect to debt securities of any series has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind

and annul the acceleration if all Events of Default, other than the non-payment of accelerated principal and interest, if any, with respect to debt securities of that series, have been cured or waived as provided in the indenture and such rescission would not conflict with any judgment or decree. We refer you to the prospectus supplement relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an Event of Default.

The trustee is entitled to be indemnified by holders of debt securities before proceeding to exercise any trust or power under the indenture at the request of such holders. The holders of at least a majority in aggregate principal amount of the then outstanding debt securities of any series may direct the time, method and place of conducting any proceedings for any remedy available to the trustee for such series, or of exercising any trust or power conferred upon the trustee with respect to the debt securities of such series. However, the trustee may decline to follow any such direction that conflicts with law or the indenture, or that the trustee determines may be unduly prejudicial to the holders of the debt securities of such series not joining in such direction.

No holder of any debt security of any series will have any right to institute any proceeding or pursue any remedy, with respect to the indenture or a series of debt securities, unless:

•

That holder has previously given to the trustee written notice of a continuing Event of Default with respect to debt securities of that series; and

•

The holders of note less than 25% in principal amount of the outstanding debt securities of that series have made written request, and offered indemnity or security satisfactory to the trustee, to the trustee to institute the proceeding as trustee, and the trustee has failed to institute the proceeding within 60 days and has not received from the holder of not less than a majority in principal amount of the outstanding debt securities of that series a direction inconsistent with that request within such 60 day periods.

No holder of debt securities under the indenture may use the indenture to prejudice the rights of another holder or to obtain a preference or priority over another holder of debt securities.

Notwithstanding any other provision in the indenture, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, premium and any interest on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment.

The indenture requires us, within 120 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture. If a Default or Event of Default occurs and is continuing with respect to the securities of any series and if it is known to a responsible officer of the trustee, the trustee shall mail to each holder of the securities of that series notice of a Default or Event of Default within 90 days after it occurs or, if later, after a responsible officer of the trustee has knowledge of such Default or Event of Default (except if such Default or Event of Default has been validly cured or waived before the trustee gives such notice). The indenture provides that the trustee may withhold notice to the holders of debt securities of any series of any Default or Event of Default (except in payment on any debt securities of that series) with respect to debt securities of that series if the trustee determines in good faith that withholding notice is in the interest of the holders of those debt securities.

Modification of the Indenture

We and the trustee may modify, amend or supplement the indenture or the debt securities of any series without the consent of any holder of any debt security:

•

to comply with covenants in the indenture described above under the heading “Consolidation, Merger and Sale of Assets”;

•

to provide for uncertificated securities in addition to or in place of certificated securities;

-13-

•

to provide for certificated debt securities in addition to uncertificated debt securities;

•

to comply with requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act;

•

to cure any ambiguity, defect or inconsistency or make any other change to the indenture or the debt securities that does not materially and adversely affect the rights of any holder of our debt securities under the indenture;

•

to provide for the issuance of and establish the form and terms and conditions of debt securities of any series as permitted by the indenture; or

•

to effect the appointment of a successor trustee with respect to the debt securities of any series and to add to or change any of the provisions of the indenture to provide for or facilitate administration by more than one trustee.

We may also modify or supplement the indenture with the written consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the modifications or supplement. The holders of at least a majority in principal amount of the outstanding debt securities of each such series affected by the modifications or supplement may waive compliance by us in a particular instance with any provision of the indenture or the debt securities of such affected series of debt securities without notice to any holder of our debt securities. We may not make any modification or amendment without the consent of the holders of each affected debt security then outstanding if that amendment will:

•

reduce the amount of debt securities whose holders must consent to an amendment, supplement or waiver;

•

reduce the rate of or change the time for payment of interest (including default interest) on any debt security;

•

reduce the principal of or premium on or change the fixed maturity of any debt security or reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation with respect to any series of debt securities;

•

make the principal of or premium or interest on any debt security payable in currency other than that stated in the debt security;

•

change the amount or time of any payment required by any debt security, or reduce the premium payable upon any redemption of any debt securities, or change the time before which no such redemption may be made;

•

waive a default in the payment of the principal of, or interest or premium, if any, on, any debt security (except a rescission of acceleration of the debt securities of any series by the holders of at least a majority in aggregate principal amount of the then outstanding debt securities of that series and a waiver of the payment default that resulted from such acceleration);

•

waive a redemption payment with respect to any debt security, or change any of the provisions with respect to the redemption of any debt securities;

•

reduce the principal amount of discount securities payable upon acceleration of maturity; or

•

make any change to certain provisions of the indenture relating to the rights of holders to institute suit with respect to the indenture or the debt securities of a series and the modification or supplement of the indenture or the debt securities of any series requiring the consent of holders of our debt securities.

The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all the debt securities of such series waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of, premium or any interest on any

-14-

debt security of that series; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration.

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, we may be discharged from any and all obligations in respect of the debt securities of any series (subject to certain exceptions). We will be so discharged upon the irrevocable deposit with the trustee, in trust, of money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. Dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money or U.S. government obligations in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities.

This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel stating that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable United States federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the holders of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred.

Defeasance of Certain Covenants. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, upon compliance with certain conditions:

•

we may omit to comply with the covenant described under the heading “Consolidation, Merger and Sale of Assets” and certain other covenants set forth in the indenture, as well as any additional covenants which may be set forth in the applicable prospectus supplement; and

•

any omission to comply with those covenants will not constitute a Default or an Event of Default with respect to the debt securities of that series, or covenant defeasance.

This is referred to as covenant defeasance. The conditions include:

•

depositing with the trustee money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. Dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal of, premium and interest on and any mandatory sinking fund payments in respect of the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities; and

•

delivering to the trustee an opinion of counsel to the effect that the holders of the debt securities of that series will not recognize income, gain or loss for United States federal income tax purposes as a result of the deposit and related covenant defeasance and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit and related covenant defeasance had not occurred.

-15-

No Personal Liability of Directors, Officers, Employees or Shareholders

None of our past, present or future directors, officers, employees or shareholders, as such, will have any liability for any of our obligations under the debt securities or the indenture or for any claim based on, or in respect or by reason of, such obligations or their creation. By accepting a debt security, each holder waives and releases all such liability. This waiver and release is part of the consideration for the issue of the debt securities. However, this waiver and release may not be effective to waive liabilities under U.S. federal securities laws, and it is the view of the SEC that such a waiver is against public policy.

Governing Law

The indenture and the debt securities, including any claim or controversy arising out of or relating to the indenture or the securities, will be governed by the laws of the State of New York.

-16-

DESCRIPTION OF WARRANTS

We may issue warrants to purchase shares of our common stock, preferred stock and/or debt securities in one or more series together with other securities or separately, as described in each applicable prospectus supplement. Below is a description of certain general terms and provisions of the warrants that we may offer. Particular terms of the warrants will be described in the applicable warrant agreements and the applicable prospectus supplement for the warrants.

The applicable prospectus supplement will contain, where applicable, the following terms of and other information relating to the warrants:

•

the number of shares of common stock or preferred stock purchasable upon the exercise of warrants to purchase such shares and the price at which such number of shares may be purchased upon such exercise;

•

the designation, stated value and terms (including, without limitation, liquidation, dividend, conversion and voting rights) of the series of preferred stock purchasable upon exercise of warrants to purchase preferred stock;

•

the principal amount of debt securities that may be purchased upon exercise of a debt warrant and the exercise price for the warrants, which may be payable in cash, securities or other property;

•

the date, if any, on and after which the warrants and the related debt securities, preferred stock or common stock will be separately transferable;

•

the terms of any rights to redeem or call the warrants;

•

the date on which the right to exercise the warrants will commence and the date on which the right will expire;

•

United States Federal income tax consequences applicable to the warrants; and

•

any additional terms of the warrants, including terms, procedures, and limitations relating to the exchange, exercise and settlement of the warrants.

Holders of equity warrants will not be entitled:

•

to vote, consent or receive dividends;

•

receive notice as shareholders with respect to any meeting of shareholders for the election of our directors or any other matter; or

•

exercise any rights as shareholders of Recro Pharma, Inc.

Each warrant will entitle its holder to purchase the principal amount of debt securities or the number of shares of preferred stock or common stock at the exercise price set forth in, or calculable as set forth in, the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to the specified time on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

A holder of warrant certificates may exchange them for new warrant certificates of different denominations, present them for registration of transfer and exercise them at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement. Until any warrants to purchase debt securities are exercised, the holder of the warrants will not have any rights of holders of the debt securities that can be purchased upon exercise, including any rights to receive payments of principal, premium or interest on the underlying debt securities or to enforce covenants in the applicable indenture. Until any warrants to purchase

-17-

common stock or preferred stock are exercised, the holders of the warrants will not have any rights of holders of the underlying common stock or preferred stock, including any rights to receive dividends or payments upon any liquidation, dissolution or winding up on the common stock or preferred stock, if any.

Prospective purchasers of warrants should be aware that special United States federal income tax, accounting and other considerations may be applicable to instruments such as warrants. The applicable prospectus supplement will describe such considerations, to the extent they are material, as they apply generally to purchasers of such warrants.

-18-

DESCRIPTION OF UNITS

We may issue units consisting of any combination of the other types of securities offered under this prospectus in one or more series. We may evidence each series of units by unit certificates that we will issue under a separate agreement. We may enter into unit agreements with a unit agent. Each unit agent will be a bank or trust company that we select. We will indicate the name and address of the unit agent in the applicable prospectus supplement relating to a particular series of units.

The following description, together with the additional information included in any applicable prospectus supplement, summarizes the general features of the units that we may offer under this prospectus. You should read any prospectus supplement and any free writing prospectus that we may authorize to be provided to you related to the series of units being offered, as well as the complete unit agreements that contain the terms of the units. Specific unit agreements will contain additional important terms and provisions and we will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from another report that we file with the SEC, the form of each unit agreement relating to units offered under this prospectus.

-20-

GLOBAL SECURITIES

Book-Entry, Delivery and Form

Unless we indicate differently in any applicable prospectus supplement, the securities initially will be issued in book-entry form and represented by one or more global notes or global securities, or, collectively, global securities. The global securities will be deposited with, or on behalf of, The Depository Trust Company, New York, New York, as depositary, or DTC, and registered in the name of Cede & Co., the nominee of DTC. Unless and until it is exchanged for individual certificates evidencing securities under the limited circumstances described below, a global security may not be transferred except as a whole by the depositary to its nominee or by the nominee to the depositary, or by the depositary or its nominee to a successor depositary or to a nominee of the successor depositary.

DTC has advised us that it is:

•

a limited-purpose trust company organized under the New York Banking Law;

•

a “banking organization” within the meaning of the New York Banking Law;

•

a member of the Federal Reserve System;

•

a “clearing corporation” within the meaning of the New York Uniform Commercial Code; and

•

a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act.

DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among its participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates. “Direct participants” in DTC include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation, or DTCC. DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others, which we sometimes refer to as indirect participants, that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of securities under the DTC system must be made by or through direct participants, which will receive a credit for the securities on DTC’s records. The ownership interest of the actual purchaser of a security, which we sometimes refer to as a beneficial owner, is in turn recorded on the direct and indirect participants’ records. Beneficial owners of securities will not receive written confirmation from DTC of their purchases. However, beneficial owners are expected to receive written confirmations providing details of their transactions, as well as periodic statements of their holdings, from the direct or indirect participants through which they purchased securities. Transfers of ownership interests in global securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the global securities, except under the limited circumstances described below.

To facilitate subsequent transfers, all global securities deposited by direct participants with DTC will be registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other nominee will not change the beneficial ownership of the securities. DTC has no knowledge of the actual beneficial owners of the securities. DTC’s records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The participants are responsible for keeping account of their holdings on behalf of their customers.

-21-

So long as the securities are in book-entry form, you will receive payments and may transfer securities only through the facilities of the depositary and its direct and indirect participants. We will maintain an office or agency in the location specified in the prospectus supplement for the applicable securities, where notices and demands in respect of the securities and the indenture may be delivered to us and where certificated securities may be surrendered for payment, registration of transfer or exchange.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any legal requirements in effect from time to time.

Redemption notices will be sent to DTC. If less than all of the securities of a particular series are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in the securities of such series to be redeemed.

Neither DTC nor Cede & Co. (or such other DTC nominee) will consent or vote with respect to the securities. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns the consenting or voting rights of Cede & Co. to those direct participants to whose accounts the securities of such series are credited on the record date, identified in a listing attached to the omnibus proxy.

So long as securities are in book-entry form, we will make payments on those securities to the depositary or its nominee, as the registered owner of such securities, by wire transfer of immediately available funds. If securities are issued in definitive certificated form under the limited circumstances described below and unless if otherwise provided in the description of the applicable securities herein or in the applicable prospectus supplement, we will have the option of making payments by check mailed to the addresses of the persons entitled to payment or by wire transfer to bank accounts in the United States designated in writing to the applicable trustee or other designated party at least 15 days before the applicable payment date by the persons entitled to payment, unless a shorter period is satisfactory to the applicable trustee or other designated party.

Redemption proceeds, distributions and dividend payments on the securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us on the payment date in accordance with their respective holdings shown on DTC records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers in bearer form or registered in “street name.” Those payments will be the responsibility of participants and not of DTC or us, subject to any statutory or regulatory requirements in effect from time to time. Payment of redemption proceeds, distributions and dividend payments to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC, is our responsibility, disbursement of payments to direct participants is the responsibility of DTC, and disbursement of payments to the beneficial owners is the responsibility of direct and indirect participants.

Except under the limited circumstances described below, purchasers of securities will not be entitled to have securities registered in their names and will not receive physical delivery of securities. Accordingly, each beneficial owner must rely on the procedures of DTC and its participants to exercise any rights under the securities and the indenture.

The laws of some jurisdictions may require that some purchasers of securities take physical delivery of securities in definitive form. Those laws may impair the ability to transfer or pledge beneficial interests in securities.

DTC may discontinue providing its services as securities depositary with respect to the securities at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor depositary is not obtained, securities certificates are required to be printed and delivered.

-22-

As noted above, beneficial owners of a particular series of securities generally will not receive certificates representing their ownership interests in those securities. However, if:

•

DTC notifies us that it is unwilling or unable to continue as a depositary for the global security or securities representing such series of securities or if DTC ceases to be a clearing agency registered under the Exchange Act at a time when it is required to be registered and a successor depositary is not appointed within 90 days of the notification to us or of our becoming aware of DTC’s ceasing to be so registered, as the case may be;

•

we determine, in our sole discretion, not to have such securities represented by one or more global securities; or

•

an Event of Default has occurred and is continuing with respect to such series of securities, we will prepare and deliver certificates for such securities in exchange for beneficial interests in the global securities.

we will prepare and deliver certificates for such securities in exchange for beneficial interests in the global securities. Any beneficial interest in a global security that is exchangeable under the circumstances described in the preceding sentence will be exchangeable for securities in definitive certificated form registered in the names that the depositary directs. It is expected that these directions will be based upon directions received by the depositary from its participants with respect to ownership of beneficial interests in the global securities.

Euroclear and Clearstream

If so provided in the applicable prospectus supplement, you may hold interests in a global security through Clearstream Banking S.A., which we refer to as “Clearstream,” or Euroclear Bank SA/NV, as operator of the Euroclear System, which we refer to as “Euroclear,” either directly if you are a participant in Clearstream or Euroclear or indirectly through organizations which are participants in Clearstream or Euroclear. Clearstream and Euroclear will hold interests on behalf of their respective participants through customers’ securities accounts in the names of Clearstream and Euroclear, respectively, on the books of their respective U.S. depositaries, which in turn will hold such interests in customers’ securities accounts in such depositaries’ names on DTC’s books.

Clearstream and Euroclear are securities clearance systems in Europe. Clearstream and Euroclear hold securities for their respective participating organizations and facilitate the clearance and settlement of securities transactions between those participants through electronic book-entry changes in their accounts, thereby eliminating the need for physical movement of certificates.

Payments, deliveries, transfers, exchanges, notices and other matters relating to beneficial interests in global securities owned through Euroclear or Clearstream must comply with the rules and procedures of those systems. Transactions between participants in Euroclear or Clearstream, on one hand, and other participants in DTC, on the other hand, are also subject to DTC’s rules and procedures.

Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers and other transactions involving any beneficial interests in global securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

Cross-market transfers between participants in DTC, on the one hand, and participants in Euroclear or Clearstream, on the other hand, will be effected through DTC in accordance with the DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by their respective U.S. depositaries; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (European time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its

-23-

settlement requirements, deliver instructions to its U.S. depositary to take DTC, and making or receiving payment in accordance with normal procedures for same-day fund settlement. Participants in Euroclear or Clearstream may not deliver instructions directly to their respective U.S. depositaries.

Due to time zone differences, the securities accounts of a participant in Euroclear or Clearstream purchasing an interest in a global security from a direct participant in DTC will be credited, and any such crediting will be reported to the relevant participant in Euroclear or Clearstream, during the securities settlement processing day (which must be a business day for Euroclear or Clearstream) immediately following the settlement date of DTC. Cash received in Euroclear or Clearstream as a result of sales of interests in a global security by or through a participant in Euroclear or Clearstream to a direct participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.

Other

The information in this section of this prospectus concerning DTC, Clearstream, Euroclear and their respective book-entry systems has been obtained from sources that we believe to be reliable, but we do not take responsibility for this information. This information has been provided solely as a matter of convenience. The rules and procedures of DTC, Clearstream and Euroclear are solely within the control of those organizations and could change at any time. Neither we nor the trustee nor any agent of ours or of the trustee has any control over those entities and none of us takes any responsibility for their activities. You are urged to contact DTC, Clearstream and Euroclear or their respective participants directly to discuss those matters. In addition, although we expect that DTC, Clearstream and Euroclear will perform the foregoing procedures, none of them is under any obligation to perform or continue to perform such procedures and such procedures may be discontinued at any time. Neither we nor any agent of ours will have any responsibility for the performance or nonperformance by DTC, Clearstream and Euroclear or their respective participants of these or any other rules or procedures governing their respective operations.

Athyrium Credit Agreement

On November 17, 2017, we entered into a five-year credit agreement (the “Credit Agreement”), with Athyrium Opportunities III Acquisition LP (“Athyrium Opportunities III”), as administrative agent and lender and Athyrium Opportunities II Acquisition LP (“Athyrium Opportunities II” and, together with Athyrium Opportunities III, “Athyrium”) as lender. Athyrium Opportunities III is an affiliate of Athyrium Opportunities II. The Credit Agreement provided for $100 million in term loans, $60 million of which was funded in November 2017. In December 2018, we amended the Credit Agreement to, among other things, revise the conditions for drawing on the additional tranches of term loans, and drew upon a $10 million term B-1 loan. On February 28, 2019, we entered into a second amendment to the Credit Agreement which, among other things, increased the amount of term loans available under the Credit Agreement from $100 million to $125 million, restructured the existing $15 million term B-2 loan and $15 million term C loan into one $55 million term B-2 loan and extended the maturity date until March 31, 2023. As of December 31, 2020, we had an outstanding balance under the Credit Agreement of $116 million.

Each of Athyrium Opportunities II and Athyrium Opportunities III acquired the Warrants on November 17, 2017 in connection with the Credit Agreement. Pursuant to the Warrants, we agreed, among other matters, to register

The selling shareholders listed in the above table may have sold or transferred, in transactions pursuant to this prospectus or exempt from the registration requirements of the Securities Act, some or all of its Warrants since the date as of which the information is presented in the above table.

Fifth Amendment to Credit Agreement and Investor Documents

On February 19, 2021, we entered into a Fifth Amendment to Credit Agreement and Investment Documents, which provided for the repayment by us of $16.0 million of the outstanding principal amount of the loans issued under the Credit Agreement, reduces the interest rate on the remaining loans outstanding and permits an equity issuance in connection with the Fifth Amendment and the transactions contemplated thereby. The Fifth Amendment also changes certain other terms and covenants contained the Credit Agreement that allow us to pursue additional acquisitions as well as easing certain requirements surrounding the financial covenants, including the liquidity we are required to maintain as well as the threshold for compliance with the consolidated leverage ratio.

Private Placement and Stock Issuance Agreement

On February 19, 2021, we entered into a Stock Issuance Agreement (the “Stock Issuance Agreement”) with Athyrium for the sale by us in a private placement (the “Private Placement”) of 2,202,420 shares (the “Athyrium Shares”) of the our common stock as consideration for Athyrium’s entrance into the Fifth Amendment and reduction in the amount of principal and interest outstanding under the Credit Agreement and payments of accrued and unpaid interest and an exit fee in an aggregate amount equal to $9,360,285.

The Private Placement was exempt from the registration requirements of the Securities Act pursuant to the exemption for transactions by an issuer not involving any public offering under Section 4(a)(2) of the Securities Act and Rule 506 of Regulation D of the Securities Act and in reliance on similar exemptions under applicable state laws. Each of Athyrium Opportunities III and Athyrium Opportunities II represented that it was an accredited investor within the meaning of Rule 501 of Regulation D, and was acquiring the securities for investment only and not with a view towards, or for resale in connection with, the public sale or distribution thereof. The Athyrium Shares were offered without any general solicitation by the Company or its representatives.

Information concerning the selling shareholders may change from time to time and any such changed information will be set forth in supplements to this prospectus or amendments to the registration statement of which this prospectus is a part if and when necessary.

Other than as described above, and in documents filed by us with the SEC pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, none of the selling shareholders has within the past three years had any position, office or other material relationship with us or any of our subsidiaries other than as a holder of our securities.

We have agreed to pay all costs, expenses and fees relating to registering the Athyrium Shares to be sold by the selling shareholders identified in this prospectus. The selling shareholders will pay any underwriting discounts, selling commissions, stock transfer taxes or similar charges incurred for the sale of the Athyrium Shares.

PLAN OF DISTRIBUTION

We may sell the securities from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods or through underwriters or dealers, through agents and/or directly to one or more purchasers. The securities may be distributed from time to time in one or more transactions:

•

at a fixed price or prices, which may be changed;

•

at market prices prevailing at the time of sale;

•

at prices related to such prevailing market prices; or

•

at negotiated prices.

The selling shareholders may from time to time sell all or a portion of the shares of our common stock beneficially owned by them and offered hereby directly or through one or more underwriters, broker-dealers or agents. If the shares of common stock are sold through underwriters or broker-dealers, the selling shareholders will be responsible for discounts or commissions payable to such underwriters or broker-dealers. The selling shareholders may use any one or more of the following methods (which may involve crosses or block transactions) when selling securities:

•

on any national stock exchange or U.S. interdealer quotation system of a registered national securities association on which the securities may be listed or quoted at the time of sale;

•

in the over-the-counter market;

•

underwritten transactions;

•

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

•

block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

•

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

•

an exchange distribution in accordance with the rules of the applicable exchange;

•

privately negotiated transactions;

•

short sales effected after the date the registration statement of which this prospectus is a part is declared effective by the SEC;

•

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•

broker-dealers may agree with the selling shareholders to sell a specified number of such securities at a stipulated price per share;

•

a combination of any such methods of sale; and

•

any other method permitted pursuant to applicable law.

The selling shareholders may also sell all or a portion of their common stock in reliance upon Rule 144 under the Securities Act or Section 4(a)(1) under the Securities Act, if available, rather than under this prospectus, provided that they meet the criteria and conform to the requirements of those provisions. The selling shareholders may also transfer, devise or gift such securities by other means not described in this prospectus. The selling shareholders are not obligated to, and there is no assurance that the selling shareholders will, sell all or any of the securities we are registering.

Each time that we or the selling shareholders sell securities covered by this prospectus, we or the selling shareholders will (to the extent required) provide a prospectus supplement or supplements that will describe the method of distribution and set forth the terms and conditions of the offering of such securities, including the offering price of the securities and the proceeds to us, if applicable.

-27-

Offers to purchase the securities being offered by this prospectus may be solicited directly. Agents may also be designated to solicit offers to purchase the securities from time to time. Any agent involved in the offer or sale of our securities will be identified in a prospectus supplement.

If a dealer is utilized in the sale of the securities being offered by this prospectus, the securities will be sold to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

If an underwriter is utilized in the sale of the securities being offered by this prospectus, an underwriting agreement will be executed with the underwriter at the time of sale and the name of any underwriter will be provided in the prospectus supplement that the underwriter will use to make resales of the securities to the public. In connection with the sale of the securities, we or the purchasers of securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for which they may act as agent. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best efforts basis and a dealer will purchase securities as a principal, and may then resell the securities at varying prices to be determined by the dealer.

Any compensation paid to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers will be provided in the applicable prospectus supplement. The selling shareholders as well as underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. We are required to pay certain fees and expenses incurred by us incident to the registration of the securities held by the selling shareholders. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof and to reimburse those persons for certain expenses.

Any common stock or preferred stock will be listed on the Nasdaq Capital Market, but any other securities may or may not be listed on a national securities exchange. To facilitate the offering of securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involve the sale by persons participating in the offering of more securities than were sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option, if any. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

We or the selling shareholders may engage in at the market offerings into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act. In addition, we or the selling shareholders may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or the selling shareholders or borrowed from us, the selling shareholders or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter

and, if not identified in this prospectus, will be named in the applicable prospectus supplement (or a post-effective amendment). In addition, we or the selling shareholders may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus and an applicable prospectus supplement. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

The specific terms of any lock-up provisions in respect of any given offering will be described in the applicable prospectus supplement.

The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business for which they receive compensation.

Additional legal matters may be passed upon for us or any underwriters, dealers or agents, by counsel that we will name in the applicable prospectus supplement.
