Productivity improves 6% and pilot training throughput doubles over prior year;

Anticipate double-digit adjusted pre-tax margin in second quarter;

Reiterated full-year adjusted pre-tax margin guidance of 9% to 12%

SEATTLE, April 20, 2023 /PRNewswire/ -- Alaska Air Group (NYSE:ALK) today reported financial results for the first quarter ending March 31, 2023, and provided outlook for the second quarter ending June 30, 2023.

"This quarter we returned to pre-pandemic levels of flying and our roadmap to profitable growth is on track," said Alaska CEO Ben Minicucci. "As we progress through the year, we have taken deliberate steps to build momentum and we are well prepared for peak summer flying. Thank you to our 23,000 employees who are the backbone of our success – I'm proud of their work to deliver operational excellence and show care for the people who fly with us each day. We are well-positioned to deliver on our full-year financial targets, including a 9% to 12% adjusted pretax margin."

Financial Highlights:

Reported net loss for the first quarter of 2023 under Generally Accepted Accounting Principles (GAAP) of $142 million, or $1.11 per share, compared to a net loss of $143 million, or $1.14 per share, for the first quarter of 2022.
Reported net loss for the first quarter of 2023, excluding special items and mark-to-market fuel hedge accounting adjustments, of $79 million, or $0.62 per share, compared to a net loss, excluding special items and mark-to-market fuel hedge accounting adjustments, of $167 million, or $1.33 per share, for the first quarter of 2022.
Resumed the share repurchase program, purchasing a total of 413,554 shares of common stock for approximately $18 million in the first quarter. The company continues to expect share repurchases of at least $100 million in 2023.
Held $2.4 billion in unrestricted cash and marketable securities as of March 31, 2023.
Ended the quarter with a debt-to-capitalization ratio of 48%, within the target range of 40% to 50%.

Operational Updates:

Ratified a two-year contract extension with more than 2,300 McGee Air Services employees represented by the IAM.
Received six 737-9 aircraft during the quarter, bringing the 737-9 fleet count to 43.
Activated new benefits for Alaska Visa Signature® cardholders, including priority boarding, lounge membership discounts, new ways to earn bonus miles and other perks. New benefits and program changes drove cash remuneration under the co-brand credit card agreement up 17% on a year-over-year basis.
Announced plans to elevate guests' regional flying experience with streaming-fast satellite Wi-Fi on E175 regional jets.
Announced three new daily nonstop flights from San Diego to Washington, D.C., Tampa and Eugene, beginning service later in 2023.
Doubled pilot training throughput compared to the same period in 2022, aided by a 75% increase in qualified flight instructors and an investment in two 737 full-flight simulators. Three additional 737 full-flight simulator deliveries are expected later this year.
Began lobby transformation projects to provide guests a more seamless travel experience; expect to roll out new bag tag stations and bag drop technology in key airports throughout 2023 and 2024.
Created a virtual reality 737 flight deck, in partnership with VRPilot, to better prepare pilots for their training experience.

Environmental, Social and Governance Updates:

Announced an agreement with Shell Aviation to advance sustainable aviation fuel (SAF) technology and infrastructure throughout the West Coast; Shell Aviation will also supply Alaska with up to 10 million gallons of SAF in Los Angeles.
Launched a partnership with the Surfrider Foundation, an organization focused on protecting coastal habitats and reducing waste across the West Coast and throughout the Hawaiian Islands.

Awards and Recognition:

Alaska's Mileage Plan named Best Airline Rewards Program by NerdWallet for its customer-friendly policies, rewards and fee structures.
Alaska and Horizon earned the Diamond Award of Excellence from the Federal Aviation Administration, recognizing the airlines' aircraft technicians for their dedication to training.

(a)	Operating income can be reconciled using the trailing twelve month operating income as filed quarterly with the SEC.

Note A: Pursuant to Regulation G, we are providing reconciliations of reported non-GAAP financial measures to their most directly comparable financial measures reported on a GAAP basis. We believe that consideration of these non-GAAP financial measures may be important to investors for the following reasons:

By excluding fuel expense and special items from our unit metrics, we believe that we have better visibility into the results of operations. Our industry is highly competitive and is characterized by high fixed costs, so even a small reduction in non-fuel operating costs can result in a significant improvement in operating results. In addition, we believe that all domestic carriers are similarly impacted by changes in jet fuel costs over the long run, so it is important for management (and thus investors) to understand the impact of (and trends in) company-specific cost drivers such as labor rates and productivity, airport costs, maintenance costs, etc., which are more controllable by management.
Cost per ASM (CASM) excluding fuel and special items, is one of the most important measures used by management and by the Air Group Board of Directors in assessing quarterly and annual cost performance.
CASM excluding fuel and special items is a measure commonly used by industry analysts, and we believe it is the basis by which they have historically compared our airline to others in the industry. The measure is also the subject of frequent questions from investors.
Adjusted income before income tax (and other items as specified in our plan documents) is an important metric for the employee incentive plan, which covers the majority of Air Group employees.
Disclosure of the individual impact of certain noted items provides investors the ability to measure and monitor performance both with and without these special items. We believe that disclosing the impact of these items as noted above is important because it provides information on significant items that are not necessarily indicative of future performance. Industry analysts and investors consistently measure our performance without these items for better comparability between periods and among other airlines.
Although we disclose our unit revenue, we do not, nor are we able to, evaluate unit revenue excluding the impact that changes in fuel costs have had on ticket prices. Fuel expense represents a large percentage of our total operating expenses. Fluctuations in fuel prices often drive changes in unit revenue in the mid-to-long term. Although we believe it is useful to evaluate non-fuel unit costs for the reasons noted above, we would caution readers of these financial statements not to place undue reliance on unit costs excluding fuel as a measure or predictor of future profitability because of the significant impact of fuel costs on our business.

GLOSSARY OF TERMS

Adjusted net debt - long-term debt, including current portion, plus capitalized operating leases, less cash and marketable securities

Adjusted net debt to EBITDAR - represents net adjusted debt divided by EBITDAR (trailing twelve months earnings before interest, taxes, depreciation, amortization, special items and rent)

Aircraft Utilization - block hours per day; this represents the average number of hours per day our aircraft are in transit

Aircraft Stage Length - represents the average miles flown per aircraft departure

ASMs - available seat miles, or "capacity"; represents total seats available across the fleet multiplied by the number of miles flown

CASM - operating costs per ASM, or "unit cost"; represents all operating expenses including fuel and special items

CASMex - operating costs excluding fuel and special items per ASM; this metric is used to help track progress toward reduction of non-fuel operating costs since fuel is largely out of our control
