\*\* Statements made in this press release include non-GAAP financial measures. Such information is provided as additional information and not as an alternative to Catalyst's financial statements presented in accordance with U.S. generally accepted accounting principles ("GAAP"). These non-GAAP financial measures are intended to enhance an overall understanding of Catalyst's current financial performance. Catalyst believes that the non-GAAP financial measures presented in this press release provide investors and prospective investors with an alternative method for assessing Catalyst's operating results in a manner that Catalyst believes is focused on the performance of ongoing operations and provides a more consistent basis for comparison between periods.

Further, non-GAAP measures of net income used by Catalyst may be different from and not directly comparable to similarly titled measures used by other companies. 

**Fourth Quarter 2025 Financial Highlights:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fourth quarter 2025 total revenues were $152.6 million, a 7.6% YoY increase

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• FIRDAPSE Q4 2025 product revenue, net was $97.6 million, an 18.3% YoY increase

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• FYCOMPA<sup>®</sup> Q4 2025 product revenue, net was
$19.6 million, due to the entry of multiple generic versions of FYCOMPA during the quarter

**Full Year 2025 Financial Highlights:** 

Full year 2025 financial results underscore robust performance, supported by sustained organic momentum and operational discipline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Full year 2025 total revenues were $589.0 million, a 19.8% YoY increase

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• FIRDAPSE full year 2025 product revenue, net was $358.4 million, a 17.1% YoY increase

**2025 Business Highlights:** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company experienced another successful year in 2025 with record revenues and record earnings, driven by
organic growth of its flagship product, FIRDAPSE, and the first full year of AGAMREE sales.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Announced updated guidelines for Small Cell Lung Cancer ("SCLC") treatment published by the National
Comprehensive Cancer Network<sup>®</sup> (NCCN) including VGCC antibody screening of SCLC patients for cancer-associated Lambert-Eaton myasthenic syndrome (LEMS) and use of amifampridine (FIRDAPSE) as a
supportive care treatment for SCLC patients also diagnosed with LEMS, helping to broaden clinical awareness, enhance diagnostic rates, and drive treatment of cancer-associated LEMS in SCLC oncology care.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Settled FIRDAPSE patent litigation with Teva Pharmaceuticals USA, Inc. and Teva Pharmaceuticals, Inc.
(collectively Teva) and Lupin Pharmaceuticals, Inc., leaving only one patent case pending against Hetero USA, Inc. The trial is currently scheduled to start on March 23, 2026, which is prior to the expiration of the automatic 30-month stay (which expires on May 26, 2026). There can be no assurance as to the outcome of this matter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Sub-licensee KYE Pharmaceuticals, Inc., announced Health Canada approval
of AGAMREE New Drug Submission, marking the first therapy approved in Canada to treat Duchenne muscular dystrophy (DMD) and address a significant unmet need for DMD patients in Canada.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Announced launch of FIRDAPSE tablets 10 mg in Japan for the indication of improving muscle weakness in patients
living with Lambert-Eaton myasthenic syndrome ("LEMS") by sub-licensee DyDo Pharma.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Continued enrollment in the SUMMIT study, an open-label, five-year follow-up study which seeks to further demonstrate the clinical value of AGAMREE and evaluate its use as a monotherapy and in combination with other treatment options.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Catalyst reviewed and evaluated over 100 prospective clinical stage acquisition targets during 2025. The Company
continues to focus its efforts on identifying immediate and near-term accretive rare disease (orphan) assets, including development-stage opportunities with established proof of concept, that provide a clinically differentiated profile and address
unmet medical needs. Catalyst continues to employ a disciplined, comprehensive and exhaustive approach to evaluate opportunities that it believes will add significant value. However, no such agreements were entered into in 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In the fourth quarter of 2025, Catalyst announced a $200 million share repurchase program, reflecting the
Company's strong balance sheet and confidence in its long-term financial outlook. Additionally, Catalyst purchased 1,124,948 shares of its outstanding common stock at an average price of $22.49 per share. To date, Catalyst has repurchased
1,740,713 shares at an average price of $22.91 for approximately $39.9 million.

Full year 2025 total revenues were $589.0 million, compared to $491.7 million for full year 2024, representing an increase of approximately 19.8% YoY. Total revenues includes license and other revenues of $0.2 million and $0.1 million, respectively, in the 2025 fiscal year and 2025 fourth quarter, compared to $2.4 million and $11,000, respectively, in 2024.

**Research and development expenses**: In the fourth quarter of 2025, research and development expenses were $1.8 million, compared to $3.8 million in the fourth quarter of 2024. Research and development expenses for full year 2025 were $12.7 million, compared to $12.6 million for full year 2024.

**Selling, general, and administrative expenses:** Selling, general, and administrative expenses for the fourth quarter of 2025 were $53.4 million, compared to $44.2 million in the fourth quarter of 2024. Selling, general, and administrative expenses for full year 2025 were $193.8 million, compared to $177.7 million for full year 2024.

------

**Amortization of intangible assets:** Amortization of intangible assets was $9.5 million in the fourth quarter of 2025, compared to $9.3 million in the fourth quarter of 2024. Amortization of intangible assets was $37.5 million in full year 2025, compared to $37.4 million for full year 2024.

**Operating income:** Operating income for the fourth quarter of 2025 was $61.8 million, compared to $62.8 million in the fourth quarter of 2024, representing a decrease of approximately 1.6%. Full year 2025 operating income was $257.8 million, compared to $195.1 million for full year 2024, representing an increase of approximately 32.1%. Operating income, GAAP net income and non-GAAP net income were all impacted by the entry of multiple generic versions of FYCOMPA during the fourth quarter of 2025.

**GAAP net income:** GAAP net income for the fourth quarter of 2025 was $52.7 million ($0.43 per basic and $0.41 per diluted share), compared to GAAP net income of $55.9 million ($0.47 per basic and $0.44 per diluted share) for the fourth quarter of 2024. GAAP net income for full year 2025 was $214.3 million ($1.75 per basic and $1.68 per diluted share), compared to full year 2024 GAAP net income of $163.9 million ($1.38 per basic and $1.31 per diluted share).

**Non-GAAP net income**: Non-GAAP net income for the fourth quarter of 2025 was $87.1 million ($0.71 per basic and $0.68 per diluted share), compared to non-GAAP net income of $88.8 million ($0.74 per basic and $0.70 per diluted share) for the fourth quarter of 2024. Non-GAAP net income for full year 2025 was $346.2 million ($2.83 per basic and $2.72 per diluted share), compared to full year 2024 non-GAAP net income of $276.3 million ($2.33 per basic and $2.21 per diluted share). Non-GAAP net income in all periods excludes from net income stock-based compensation, depreciation, amortization of intangible assets, and the income tax provision.

**Cash and cash equivalents:** Cash and cash equivalents were $709.2 million as of December 31, 2025. The cash and cash equivalents balance at December 31, 2025, was impacted by a change in the payment terms resulting from the renegotiation of a contract between the Company and a customer. Under the revisions to the contract with this customer, among other changes, the Company is now paying reduced fees to the customer (which are recorded as a reduction in gross-to-net expenses), but the customer is paying amounts due on its obligations to Catalyst on a monthly basis rather than a semi-monthly basis (as required under the previous contract terms). As a result of this change, a payment of approximately $27.0 million that the Company would have received at the end of December 2025, based upon the previous due date (under the previous contract terms) was received in early January 2026. Additionally, during the fourth quarter of 2025, the amount invested in the Company's shares through the announced $200 million share repurchase program was approximately $25.3 million at an average price per share of $22.49, resulting in a reduction of 1,124,948 million shares outstanding.

More detailed financial information and analysis of our financial condition and results of operations can be found in our Annual Report on Form 10-K for fiscal year 2025, which was filed with the U.S. Securities and Exchange Commission on February 25, 2026.

**Full Year 2026 Outlook** 

For full year 2026, the Company forecasts total revenues to be between $615 million and $645 million, reflecting continued robust growth in product revenue, net from both FIRDAPSE and AGAMREE.

------

FIRDAPSE's product revenue, net for fiscal 2026 is expected to be between $435 million and $450 million, growth of between 21.4% and 25.6% compared to 2025, driven by our life-cycle management initiatives in Idiopathic and Cancer-Associated LEMS.

AGAMREE's product revenue, net for 2026 is expected to be between $140 million and $150 million, growth of between 19.6% and 28.1% compared to 2025, reflecting the product's continued market adoption and commercial momentum.

FYCOMPA's product revenue, net for 2026 is expected to be between $40 million and $45 million, driven by ongoing market demand despite the loss of patent exclusivity at the end of May 2025, for FYCOMPA tablets, which currently has three generic competitors, and December 2025 for FYCOMPA oral suspension, which currently has one generic competitor.

**Cost of sales:** On January 25, 2026, the Company completed seven years from the date of first commercial sale of FIRDAPSE in the U.S. On that date, the royalty on net U.S. sales that the Company previously paid to Catalyst's licensor at a tiered rate of 7-10% of net U.S. sales of FIRDAPSE expired. Also, on January 1, 2026, as part of the Company's acquisition and license agreement regarding RUZURGI<sup>®</sup> (amifampridine) with Jacobus, the royalty rate the Company pays Jacobus on net U.S. sales of any amifampridine product increased from 1.5% to 2.5%. In addition to these two changes, there was also another change in FIRDAPSE royalties owed by the Company on net U.S. sales that occurred in November 2025. On November 28, 2025, due to seven years passing from the date of the FDA approval of FIRDAPSE, the royalty on net U.S. sales of FIRDAPSE that the Company owes to its licensor to satisfy its licensor's royalty obligations to another third-party licensor decreased from 7% of net U.S. sales to 3.5%. As a result, beginning on January 26, 2026, the overall royalty rate that the Company will pay to its upstream licensors for net U.S. sales of FIRDAPSE<sup>®</sup> will be 6%, which is down from a previous maximum rate of 18.5%.

AGAMREE royalties are expected to remain relatively flat as a percentage of product revenue, net and there will be a full year of the sales-based milestone payment based on the achievement of the milestone in the fourth quarter of 2025. Further, the Company will be required to pay a 6% royalty, based on net product revenue, to the product licensor for FYCOMPA starting in July 2026.

**Research and development expenses:** Due to the ongoing activities relating to the SUMMIT study as well as life cycle management evaluation for AGAMREE, the Company anticipates research and development expenses in 2026, absent another acquisition, to be between $17.5 million and $22.5 million. If the Company completes an acquisition, its R&D expenses may become more significant, particularly if it acquires rights to a product prior to that product receiving regulatory approval.

**Selling, general, and administrative expenses:** The Company anticipates an increase in selling, general and administrative expenses in 2026 compared to 2025, primarily driven by increased commercial activities to continue to support FIRDAPSE and AGAMREE as well as continued support of its business development strategy, which has been expanded for 2026 to include development opportunities with established proof of concept and a clear regulatory path.

------

**Tax rate:** The Company anticipates that its effective tax rate will be relatively consistent for 2026 compared to 2025 and 2024.
