Rhea-AI Filing Summary

BioCryst Pharmaceuticals entered into a new Loan Agreement on January 23, 2026 providing $400 million of initial term loans to help fund its acquisition of Astria Therapeutics and related costs, as well as for working capital and general corporate purposes. The term loans mature on January 23, 2031 and require quarterly interest-only payments, with all principal due at maturity.

The loans bear interest at three-month SOFR, with a floor of 1.75%, plus 4.50% per year, and BioCryst may pay up to 200 basis points of interest in kind until the second anniversary of closing, at which time the margin on those loans increases by 0.50% for the relevant period. The facility is secured by substantially all assets of BioCryst and its subsidiaries and includes customary covenants and events of default, plus prepayment premiums that step down from 3.00% to 0% over four years.

On the same date, BioCryst completed its merger with Astria Therapeutics, with Astria becoming a wholly owned subsidiary. Each share of Astria common stock was converted into the right to receive 0.59 BioCryst share plus $8.55 in cash, subject to standard adjustments, combining the two companies’ businesses.

Positive

  • Strategic acquisition completed: BioCryst closed the merger with Astria Therapeutics, adding Astria as a wholly owned subsidiary and expanding its business portfolio.
  • Long-dated financing in place: The $400 million term loan matures in 2031 with interest-only payments, providing multi-year funding stability to support the Astria transaction and ongoing operations.

Negative

  • Higher leverage and interest burden: The secured $400 million term loan with SOFR plus 4.50% interest and prepayment premiums increases BioCryst’s fixed financing costs and limits financial flexibility through covenants and asset liens.

Insights

BioCryst uses $400M secured term loan to fund the Astria acquisition, adding leverage with structured prepayment costs.

The company has entered a $400 million term loan maturing on January 23, 2031, structured as interest-only until maturity. The interest rate is three-month SOFR with a 1.75% floor plus 4.50%, which locks in relatively high fixed spread funding and adds a meaningful fixed cash interest burden over time. The option to pay up to 200 basis points of interest in kind for two years provides near-term cash flexibility at the cost of increasing principal.

The loan is secured by substantially all assets of BioCryst and its subsidiaries and comes with customary covenants restricting additional debt, asset sales, dividends, and certain transactions. These constraints, together with mandatory prepayment triggers on change of control and certain asset sales, can limit future financial flexibility. Prepayment premiums up to the fourth anniversary, including make-whole-like interest in the first year, economically encourage keeping the debt in place for several years.

Strategically, BioCryst used this financing to close the merger with Astria Therapeutics, where each Astria share was exchanged for 0.59 BioCryst share plus $8.55 in cash. The combination adds Astria as a wholly owned subsidiary, so subsequent filings and financials will be key to understanding how the acquired assets and additional leverage affect BioCryst’s revenue, R&D pipeline, and overall risk profile.

Item 1.01.
Entry Into a Material Definitive Agreement.

On January 23, 2026 (the “Closing Date”), BioCryst Pharmaceuticals, Inc., a Delaware corporation (“BioCryst”), entered into a Loan Agreement (the “Loan Agreement”), by and among BioCryst, as borrower, the guarantors from time to time party thereto, Blackstone Alternative Credit Advisors LP and Blackstone Life Sciences Advisors L.L.C., as the Blackstone representatives thereunder, the lenders from time to time party thereto and Wilmington Trust, National Association, as agent. The Loan Agreement provides for initial term loans in the principal amount of $400 million (the “Term Loans”), which were funded on the Closing Date.

BioCryst intends to utilize the proceeds from the Term Loans solely (i) to pay the cash portion of the consideration required to consummate the Merger (as defined below) and pay other expenses related to the Merger, (ii) to pay the fees, premiums, expenses and other transaction costs incurred in connection with the transactions related to the Merger and the Loan Agreement, and (iii) for working capital and other general corporate purposes of BioCryst and its subsidiaries.  The maturity date of the Term Loans under the Loan Agreement is January 23, 2031 (the “Maturity Date”), the fifth anniversary of the Closing Date.

The Loan Agreement provides for quarterly interest-only payments until the Maturity Date, with the unpaid principal amount of the outstanding Term Loans due and payable on the Maturity Date.  Until the second anniversary of the Closing Date, BioCryst has the option to make a portion of the applicable interest payment on the Term Loans in kind (a “PIK Interest Payment”) by capitalizing as principal on the Term Loans up to 200 basis points of interest that is payable for such interest period. The Term Loans will bear interest at a rate equal to the three-month SOFR rate, which shall be no less than 1.75%, plus 4.50%, per annum and, for any interest period in which a PIK Interest Payment is made, the interest margin for such borrowing will be increased by 0.50% per annum on all Term Loans for which BioCryst has made a PIK Interest Payment for the applicable interest period.

BioCryst is required to make a mandatory prepayment of the Term Loans (i) upon the occurrence of a change of control of BioCryst, (ii) upon the incurrence of certain indebtedness not permitted under the Loan Agreement, and (iii) subject to certain exceptions and thresholds, upon the receipt of proceeds from the sale of certain assets of BioCryst and its subsidiaries, or from the receipt of proceeds from certain events of loss related to assets of BioCryst and its subsidiaries.  BioCryst may make voluntary prepayments under the Term Loans, in whole or in part. Prepayments are subject to a yield protection premium equal to (i) with respect to any prepayment made prior to the first anniversary of the Closing Date, the sum of (1) 3.00% of the principal amount of the Term Loan being prepaid plus (2) the aggregate amount of all interest that would have accrued on the principal amount of the Term Loan being prepaid from the date of prepayment through the first anniversary of the Closing Date; (ii) with respect to any prepayment made on or after the first anniversary and prior to the second anniversary of the Closing Date, 3.00% of the principal amount of the Term Loan being prepaid; (iii) with respect to any prepayment made on or after the second anniversary and prior to the third anniversary of the Closing Date, 2.00% of the principal amount of the Term Loan being prepaid; (iv) with respect to any prepayment made on or after the third anniversary and prior to the fourth anniversary of the Closing Date, 1.00% of the principal amount of the Term Loan being prepaid; and (v) with respect to any prepayment made on or after the fourth anniversary of the Closing Date, 0.00% of the principal amount of the Term Loan being prepaid.  The foregoing yield protection premium is also payable upon certain mandatory prepayments or an acceleration that occurs within such periods.

The Loan Agreement also 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 the ability of BioCryst and certain of its subsidiaries to, among other things, dispose of assets, engage in mergers, acquisitions and similar transactions, incur additional indebtedness, grant liens, make investments, pay dividends or make distributions or certain other restricted payments in respect of equity, prepay certain other indebtedness, enter into restrictive agreements, undertake fundamental changes or amend certain material contracts, among other customary covenants, in each case subject to certain exceptions.

A failure to comply with the covenants in the Loan Agreement, or an occurrence of any other event of default, could permit the lenders under the Loan Agreement to declare the borrowings thereunder, together with accrued interest and fees, and any applicable yield protection premium, to be immediately due and payable.


BioCryst’s obligations under the Loan Agreement are secured by a security interest in, subject to certain exceptions, substantially all of the assets of BioCryst and its subsidiaries.

The foregoing description of the Loan Agreement is not complete and is qualified in its entirety by reference to the full text of the Loan Agreement, which will be filed as an exhibit to BioCryst’s next periodic report filed with the U.S. Securities and Exchange Commission (the “SEC”).

Item 2.01.
Completion of Acquisition or Disposition of Assets.

On the Closing Date, BioCryst completed the transactions contemplated by the Agreement and Plan of Merger, dated as of October 14, 2025 (the “Merger Agreement”), by and among BioCryst, Axel Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of BioCryst (“Merger Sub”), and Astria Therapeutics, Inc., a Delaware corporation (“Astria”). On the Closing Date, Merger Sub merged with and into Astria (the “Merger”), with Astria surviving the Merger as a wholly owned subsidiary of BioCryst. The Merger was more fully described in BioCryst’s Registration Statement on Form S-4 (File No. 333-291678) filed with the SEC on November 20, 2025, and amended on December 15, 2025 (the “Registration Statement”).

At the effective time of the Merger (the “Effective Time”), under the terms of the Merger Agreement, each share of common stock, par value $0.001 per share, of Astria (“Astria Common Stock”) issued and outstanding immediately prior to the Effective Time (excluding shares held by BioCryst, Astria or their wholly owned subsidiaries or dissenting stockholders) was converted into the right to receive (i) 0.59 of a share of common stock, par value $0.01 per share, of BioCryst and, if applicable, cash in lieu of fractional shares, and (ii) $8.55 in cash, without interest, subject to applicable withholding taxes. Astria’s Series X Convertible Preferred Stock, par value $0.001 per share, outstanding options to purchase shares of Astria Common Stock, pre-funded warrants to purchase shares of Astria Common Stock and other warrants to purchase shares of Astria Common Stock were treated as set out in the Merger Agreement and more fully described in the Registration Statement.
