Aerojet Rocketdyne Holdings, Inc. increased its top line by 11% year over year, achieving its highest ever first quarter sales at $566 million. Backlog of $6.8 billion is an increase of 6% from $6.4 billion a year ago, with $2.4 billion currently expected to convert to sales in the next 12 months. Backlog includes an award announced in the quarter from Lockheed Martin Corporation to power additional Terminal High Altitude Area Defense (“THAAD”) interceptors. The award is for lots 13/14 as well as foreign military sales. The Adjusted EBITDAP margin of 10.4% in the quarter includes a one-time, out of period adjustment of $6.5 million related to excess costs on fixed-price contracts in nearly complete or inactive status as well as $5 million additional stock compensation related to changes in the fair value of previously granted stock appreciation rights. Excluding changes in contract estimates and stock compensation, the Adjusted EBITDAP margin was 13.7% in the first quarter compared with 13.9% in the prior year. Free cash outflow of $34 million is significantly improved from an outflow of $77 million in the first quarter of 2022.

“We continue to win important new programs as evidenced by our steady backlog position, and we started the year strong with our highest sales quarter ever. We’re also pleased to have entered into a $216 million cooperative agreement with the Department of Defense’s Office of Manufacturing Capability Expansion and Investment Prioritization (“MCEIP”) which will allow us to build additional modernized facilities, purchase advanced equipment, and automate manufacturing processes at our Arkansas, Alabama and Virginia sites,” said Eileen P. Drake, Aerojet Rocketdyne CEO and president. “These funds will support increased production of rocket propulsion for Javelin, Stinger and the Guided Multiple Launch Rocket System (“GMLRS”) and will build on Aerojet Rocketdyne’s ongoing investments in modern, efficient facilities and innovative technologies and processes to support the development of next generation capabilities for Tactical missile systems, advanced Hypersonics, Strategic Missile and Missile Defense systems, including the Next Generation Interceptor (“NGI”) and the Sentinel Ground Based Strategic Deterrent. This agreement reflects the continued support and commitment to excellence of the Company, our customers and the end users of our products.”

First quarter of 2023 compared with first quarter of 2022

The increase in net sales was primarily driven by an increase on the NGI, RL10, and Patriot GEM-T programs. Net income was unchanged for the periods.

Backlog

As of March 31, 2023, the Company's total remaining performance obligations, also referred to as backlog, totaled $6.8 billion. The Company expects to recognize approximately 35%, or $2.4 billion, of the remaining performance obligations as sales over the next twelve months, an additional 27% the following twelve months, and 38% thereafter. A summary of the Company's backlog is as follows:

	March 31, 2023		December 31, 2022
	(In billions)
Funded backlog	$	3.0	$	3.1
Unfunded backlog		3.8		3.7
Total backlog	$	6.8	$	6.8

Total backlog includes both funded backlog (unfilled orders for which funding is authorized, appropriated and contractually obligated by the customer) and unfunded backlog (firm orders for which funding has not been appropriated). Indefinite delivery and quantity contracts and unexercised options are not reported in total backlog. Backlog is subject to funding delays or program restructurings/cancellations, which are beyond the Company's control.

L3Harris Technologies, Inc. (“L3Harris”) Merger Agreement

On December 17, 2022, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”), with L3Harris and Aquila Merger Sub Inc., a Delaware corporation and a wholly-owned subsidiary of L3Harris (“Merger Sub”), pursuant to which, subject to the terms and conditions thereof, Merger Sub will merge with and into the Company (the “Merger”) with the Company being the surviving corporation and a wholly-owned subsidiary of L3Harris.

Subject to the terms and conditions set forth in the Merger Agreement, each share of the Company's common stock outstanding as of immediately prior to the effective time of the Merger will be canceled and converted into the right to receive $58.00 in cash, without interest, plus, if the closing occurs after September 17, 2023, $0.0025 for each calendar day elapsed after such date up to and including the closing date.

On March 15, 2023, the Company received a request for additional information from the Federal Trade Commission as part of the regulatory review process for the acquisition of the Company by L3Harris.

On March 16, 2023, the stockholders of the Company voted in favor of approving the Merger Agreement at a special meeting.

Closing of the Merger is anticipated to occur in 2023, subject to various customary conditions, including regulatory clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

In the three months ended March 31, 2023, the Company recorded $20.0 million of costs associated with the Merger with L3Harris. The components of the Merger costs are as follows (in millions):

Consulting and other professional costs	$	11.4
Legal		4.6
Internal labor (including $0.8 million of recurring employee costs)		4.0
	$	20.0

Out of Period Adjustment

During the three months ended March 31, 2023, the Company recorded an out of period adjustment related to the completeness and accuracy of its accounting for excess costs on fixed-price contracts in nearly complete or inactive status. The out of period adjustment resulted in a decrease in net sales of $6.0 million, an increase in cost of sales of $0.5 million, and a decrease in the income tax provision of $1.7 million in the three months ended March 31, 2023. The Company has evaluated the effects of this error, both qualitatively and quantitatively, and does not believe the correction was material to any current or prior interim or annual periods that were affected.

Excluded from segment performance are: corporate income and expenses, interest expense, interest income, income taxes, and unusual items not related to the segment. The Company believes that segment performance provides information useful to investors in understanding its underlying operational performance.

Use of Unaudited Non-GAAP Financial Measures

Adjusted EBITDAP, Adjusted Net Income and Adjusted EPS

The Company provides the Non-GAAP financial measures of its performance called Adjusted EBITDAP, Adjusted Net Income and Adjusted EPS. The Company uses these metrics to measure its operating and total Company performance. The Company believes that for management and investors to effectively compare core performance from period to period, the metrics should exclude items that are not indicative of, or are unrelated to, results from the ongoing business operations, such as retirement benefits (pension and postretirement benefits), significant non-cash expenses, the impacts of financing decisions on earnings, and items incurred outside the ordinary, ongoing and customary course of business. Accordingly, the Company defines Adjusted EBITDAP as GAAP net income adjusted to exclude interest expense, interest income, income taxes, depreciation and amortization, retirement benefits net of amounts that are recoverable under the Company's U.S. government contracts, and unusual items. Adjusted Net Income and Adjusted EPS exclude retirement benefits net of amounts that are recoverable under its U.S. government contracts and unusual items which the Company does not believe are reflective of such ordinary, ongoing and customary activities. Adjusted Net Income and Adjusted EPS do not represent, and should not be considered an alternative to, net income or diluted EPS as determined in accordance with GAAP.

_________

(1)  The income tax impact is calculated using the federal and state statutory rates in the corresponding period.

Free Cash Flow

The Company also provides the Non-GAAP financial measure of Free Cash Flow. Free Cash Flow is defined as cash flow from operating activities less capital expenditures. Free Cash Flow should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to cash flows from operations presented in accordance with GAAP. The Company uses Free Cash Flow, both in presenting its results to stakeholders and the investment community, and in the Company's internal evaluation and management of the business. Management believes that this financial measure is useful because it provides supplemental information to assist investors in viewing the business using the same tools that management uses to evaluate progress in achieving the Company's goals. The following table summarizes Free Cash Flow:

	Three months ended March 31,
		2023			2022
	(In millions)
Net cash used in operating activities	$	(32.8	)	$	(75.0	)
Capital expenditures		(1.6	)		(2.2	)
Free Cash Flow	$	(34.4	)	$	(77.2	)

Because the Company's method for calculating these Non-GAAP measures may differ from other companies’ methods, the Non-GAAP measures presented above may not be comparable to similarly titled measures reported by other companies. These measures are not recognized in accordance with GAAP, and the Company does not intend for this information to be considered in isolation or as a substitute for GAAP measures.
