Repligen Reports Second Quarter 2023 Financial Results

and Updates Full Year 2023 Financial Guidance

•

Reports second quarter revenues of $159.2 million as reported, and base business revenues of $157.1 million, down 9% year-over-year

•

Adjusts full year revenue guidance to range of $635-$665 million

WALTHAM, Mass., August 02, 2023 — Repligen Corporation (NASDAQ:RGEN), a life sciences company focused on bioprocessing technology leadership, today reported financial results for its second quarter (Q2) and first half (H1) of 2023, covering the three- and six-month fiscal periods ended June 30, 2023. Provided in this press release are financial performance highlights, updates to our guidance for the year 2023 and access information for today’s webcast and conference call.

Tony J. Hunt, President and Chief Executive Officer of Repligen said, “2023 continues to be a challenging year for bioprocessing. Our base business performance in the second quarter and first half of 2023 held up reasonably well with base revenues down 9% and 3% respectively. Our Analytics, Proteins and Chromatography franchises were all up mid-single to double digits in the quarter and year-to-date, with most of the overall decline in revenues coming from Filtration, where the vast majority of current headwinds exist. In Cell & Gene Therapy, sequential revenue growth of 7% in the quarter was driven by customers scaling up with our technologies and new drug approvals. Pharma base business orders weakened in the second quarter, due to inventory overhang and longer purchase approval timelines. We remain optimistic that we will manage through these headwinds by the end of this year, supported by a growing pipeline of opportunities and projected increase in orders in the fourth quarter. However, 2023 remains a challenging year and we now expect a decline of 7% at midpoint for our base business.”

FINANCIAL GUIDANCE

Our financial guidance for the fiscal year 2023 is based on expectations for our existing business. Our GAAP and Adjusted (non-GAAP) guidance includes the impact of our FlexBiosys acquisition and excludes the impact of potential additional acquisitions, and future fluctuations in foreign currency exchange rates. Our GAAP guidance also includes an initial estimate of $6 million in severance charges associated with our plans to rebalance resources during the second half of 2023.

YEAR 2023 GUIDANCE:

•

Total reported revenue is expected to be in the range of $635-$665 million, compared to our previous guidance of $720-$760 million. This represents a year-over-year decrease of 17%-21%, compared to our previous guidance, a decrease of 5%-10%. We expect COVID-related revenue of approximately $30 million, compared to our previous guidance of $30-$40 million. For our base business, we are expecting revenues to be down 5%-10%, compared with our previous guidance of a 4%-8% increase. For the full year, foreign currency impact is expected to be nominal.

•

Gross margin is expected to be 49.5%-50.5% on a GAAP basis, and 50%-51% on a non-GAAP basis, compared to our previous guidance of 52%-53% for both GAAP and non-GAAP.

•

Income from operations is expected to be in the range of $57-$63 million on a GAAP basis, compared to our previous guidance of $111-$116 million. Adjusted (non-GAAP) income from operations is expected to be in the range of $104-$110 million, compared with our previous guidance of $153-$158 million. Adjusted operating margin is expected to be in the range of 16%-17%, compared to our previous guidance of 20.5%-21.5%.

•

Net income is expected to be in the range of $57-$61 million on a GAAP basis, compared to our previous guidance of $97-$101 million. Adjusted (non-GAAP) net income is expected to be in the range of $98-$102 million, compared to our previous guidance of $134-$138 million. This reflects a tax rate of 20% on adjusted pre-tax income, consistent with our previous guidance.

•

Net income per share (GAAP) is expected to be in the range of $1.00-$1.08 on a fully diluted basis, compared with our previous guidance of $1.70-$1.77. Adjusted net income per share (non-GAAP) is expected to be in the range of $1.72-$1.80 on a fully diluted basis, compared to our previous guidance of $2.35-$2.42.

Our non-GAAP guidance for the fiscal year 2023 excludes the following items:

•

$6.0 million estimated restructuring costs

•

$2.3 million estimated acquisition and integration expenses in SG&A.

•

$30.0 million estimated intangible amortization expense in SG&A.

•

$1.8 million in amortization of debt issuance expense (Other income (expense)).

•

$8.5 million estimated contingent consideration expense related to our Avitide and FlexBiosys acquisitions, primarily reflecting time value of money implications.

Our non-GAAP guidance for the fiscal year 2023 includes:

•

An income tax increase of $7.6 million, representing the tax impact on acquisition and integration costs, intangible amortization and contingent consideration expense, and amortization of debt issuance costs.

All reconciliations of GAAP to adjusted (non-GAAP) guidance are detailed in the tables included later in this press release.

Conference Call and Webcast Access

The replay dial-in numbers are (877) 344-7529 from the U.S., (855) 669-9658 from Canada and (412) 317-0088 for international callers. Replay listeners must provide the passcode 6507297.

Non-GAAP Measures of Financial Performance

To supplement our financial statements, which are presented on the basis of U.S. generally accepted accounting principles (GAAP), the following non-GAAP measures of financial performance are included in this release: revenue growth rate at constant currency; adjusted gross profit, adjusted gross margin and adjusted operating margin; adjusted cost of sales; adjusted R&D expense; adjusted SG&A expense; adjusted income from operations; adjusted net income; adjusted net income per share-diluted; earnings before interest, taxes, depreciation and amortization (EBITDA); and adjusted EBITDA. The Company provides base revenue growth rates, which excludes all COVID-related revenue, and the impact of acquisition revenue for current year periods that have no prior year comparables, in order to facilitate a comparison of its current revenue performance. The Company provides revenue growth rates at constant currency, which exclude the impact of foreign currency translation, in order to facilitate a comparison of its current revenue performance to its past revenue performance. To calculate revenue growth rates in constant currency, the Company converts actual net sales from local currency to U.S. dollars using constant foreign currency exchange rates in the current and prior period.

The Company’s non-GAAP financial results and/or non-GAAP guidance exclude the impact of: acquisition and integration costs, restructuring costs, intangible amortization costs, contingent consideration related to the Company’s acquisitions, amortization of debt issuance costs related to the Company’s convertible debt, and the related impact on tax of non-GAAP charges. These costs are excluded because management believes that such expenses do not have a direct correlation to future business operations, nor do the resulting charges recorded accurately reflect the performance of our ongoing operations for the period in which such charges are recorded.

A reconciliation of GAAP to adjusted non-GAAP financial measures is included as an attachment to this press release. When analyzing the Company’s operating performance and guidance investors should not consider non-GAAP measures as substitutable for the comparable financial measures prepared in accordance with GAAP.

Under ASU 2020-06, the Company is required to reflect the dilutive effect of the 2019 Notes by application of the if-converted method. Prior to filing the Second Supplemental Indenture on March 4, 2022, the Company had the option to settle the conversion of the 2019 Notes in cash, stock or a combination of the two. Therefore, from January 1, 2022 (the date the Company adopted ASU 2020-06) to March 4, 2022, the Company included 3,474,429 shares in the denominator of the weighted average six months ended June 30, 2022 diluted EPS calculation. Subsequent to March 4, 2022, after the Second Supplemental Indenture became effective, the Company irrevocably elected to settle the conversion principal in cash and only the premium in shares of the Company’s common stock. Therefore, from March 5, 2022 to March 31, 2022 the Company included 980,525 shares and from April 1, 2022 to June 30, 2022 842,233 shares in the denominator of the weighted average six months ended June 30, 2022 diluted EPS calculation. Under the if-converted method, the Company was also required to exclude amortization of debt issuance cost and interest charges applicable to the convertible debt from the numerator of the diluted EPS calculation for the period from January 1, 2022 to March 4, 2022, assuming the interest on convertible debt was never recognized for that period. For the six months ended June 30, 2022 the Company excluded amortization of debt issuance costs and interest charges for the period January 1, 2022 to March 4, 2022 of $0.4 million (tax effected) from the numerator.
