Exhibit 99.1

CEO Remarks

Good morning, and welcome to the Ally Financial annual stockholders meeting. I’m Jeff Brown, Chief Executive Officer. It’s a pleasure to speak with you today.

2017 was an exceptional year for our company. We made substantial progress in expanding and diversifying the products we offer our customers, while growing deposits, maintaining our leading position in auto finance, and delivering strong financial results. And I’m pleased the market acknowledged the successful year we had, with stockholders seeing a 56%* total return on Ally stock in 2017 – among the best in banking.

This morning, I’ll talk about our financial and operational accomplishments while providing my perspective on our strategy going forward.

Financially, we had a number of achievements in 2017, driven by strong risk-adjusted returns in the auto finance business, efficient capital management, and further progress optimizing our funding structure by growing deposits and the structural roll-down of high cost debt.

Additionally, we achieved a significant milestone on the regulatory front when the Federal Reserve released Ally Bank from certain legacy capital and liquidity requirements, including the commitment to maintain a tier 1 leverage ratio of at least 15%. This was a very meaningful development, allowing us to manage our capital and funding much more efficiently. When given an opportunity to compete on a level playing field, I’m very confident in what we can bring to the table, and this regulatory normalization allowed us to do exactly that – compete on the same basis as other banks.

Operationally, we made progress in executing on our strategic objectives, including optimizing our auto finance business, growing our customer base, and building out our new product offerings.

Our auto finance business reached an inflection point in 2017, as our transition to a diversified full credit spectrum retail auto loan mix was largely completed. During this transition, we focused on optimizing risk-adjusted returns, with Estimated Retail Auto Originated Yield⁴ up 42 basis points in 2017, while the weighted average FICO score on new retail originations also increased – demonstrating our ability to maintain credit discipline while leveraging our leading platform to book business that makes sense for us and is good for our customers. In fact, last year, we helped nearly 1.2 million retail customers finance the purchase of a vehicle.

Our commercial auto finance portfolio serves more than 18,000 dealers across all 50 states and we saw the yield on that portfolio increase by 46 basis points while registering the sixth consecutive year in which portfolio losses were less than or equal to one basis point.

Our auto finance business continues to position itself for the future, entering into agreements and relationships with emerging online entrants while expanding our digital and direct-to-consumer capabilities with the rollout of Clearlane. The adaptability and resilience of our auto finance franchise is second to none, and we’ve consistently demonstrated the ability to face a challenge, find a solution, and execute on a plan. In the course of a little more than 4 years, we had two OEM exclusivity agreements expire and a large portion of our lease business internalized with a competitor, yet today we stand stronger and more diversified than ever. Our proven ability to innovate and leverage our deep industry experience to

serve our customers at the highest level gives me confidence we’ll continue to find success as the auto ecosystem evolves and new trends emerge.

Away from auto finance, our deposits business had another terrific year. This franchise is foundational to our customer acquisition strategy and I’m very proud that we grew retail deposits by $11.3 billion while adding nearly 200 thousand retail deposit customers in 2017. These accomplishments are even more impressive given the competitive dynamics of the deposit market, and are clear proof that our brand and value proposition resonate with customers. Since we created Ally Bank back in 2009, we’ve continuously innovated and improved the customer experience, but our core approach has remained unchanged. We offer:

Our ability to consistently deliver this value proposition across products will be important as we expand and grow our consumer and commercial product offerings. Entering new channels and introducing new products are not easy and we will continuously learn and adapt, as we’ve always done. The seeds have been planted in mortgage, wealth management and credit card, allowing us to do more for our customers, and we see opportunities for these products to grow more meaningfully in 2018, particularly wealth management and mortgage. On the commercial side, our corporate finance business introduced new industry verticals in 2017, which contributed to growing pre-tax earnings by 60% year-over-year, and we see attractive opportunities for that business as well.

Overall, I was very pleased with our financial and operational performance in 2017 and I’m energized to build upon this momentum in 2018. It’s an exciting time for Ally. We’ve created the model for what a customer-centric digital bank should look like, and as we build scale in our products, grow the customer base, and further improve profitability, I’m confident we’ll continue to drive attractive returns for our stockholders.

Before I wrap up, I’d like to spend a minute on our culture. Ally is a diverse and inclusive company where people want to work, and I think that’s a big reason why Ally is a company where people want to bank. We have a strong and distinctive culture focused on “doing it right” that attracts great talent, and we’ve received a number of accolades that reflect that, including “Best Bank to Work For” and “Best Companies to work for Women and Millennials.” And just a few weeks ago, we were named “Best Company to Work for in Detroit,” a city that has been integral to the heritage of this company and a community that we’re deeply committed to. The passion and diligence I see from our associates every day is humbling and I am privileged to lead an organization with such wonderful talent.

In closing, I want to thank our 8,000+ associates across the country for their dedication and commitment to ‘doing it right’ day in and day out, as well as my fantastic leadership team for their tireless efforts in guiding the strategic direction of this company. I’d also like to thank the board of directors for the service and invaluable advice they provide.

Lastly, I’d like to thank our valued stockholders for their continued support as we build the preeminent digital bank.

I am honored to be CEO of this great company and couldn’t be more excited about our future.

Thank you.

Financial Reconciliations

Adjusted earnings per share (Adjusted EPS) is a non-GAAP financial measure that adjusts GAAP EPS for revenue and expense items that are typically strategic in nature or that management otherwise does not view as reflecting the operating performance of the company. Management believes Adjusted EPS can help the reader better understand the operating performance of the core businesses and their ability to generate earnings. In the numerator of Adjusted EPS, GAAP net income attributable to common shareholders is adjusted for the following items: (1) excludes discontinued operations, net of tax, as Ally is primarily a domestic company and sales of international businesses and other discontinued operations in the past have significantly impacted GAAP EPS, (2) adds back the tax-effected non-cash Core OID, (3) adds back tax-effected repositioning items primarily related to the extinguishment of high-cost legacy debt and strategic activities, (4) excludes certain discrete tax items that do not relate to the operating performance of the core businesses, and (5) adjusts for preferred stock capital actions (e.g., Series A) that have been taken by the company to normalize its capital structure.

Adjusted tangible book value per share (Adjusted TBVPS) is a non-GAAP financial measure that reflects the book value of equity attributable to shareholders even if Core OID balance were accelerated immediately through the financial statements. As a result, management believes Adjusted TBVPS provides the reader with an assessment of value that is more conservative than GAAP common shareholder’s equity per share. Adjusted TBVPS generally adjusts common equity for (1) goodwill and identifiable intangibles, net of DTLs, (2) tax-effected Core OID balance to reduce tangible common equity in the event the corresponding discounted bonds are redeemed/tendered and (3) Series G discount which reduces tangible common equity as the company has normalized its capital structure.

Note: in December 2017 tax-effected Core OID balance was adjusted from a statutory U.S. Federal tax rate of 35% to 21% (“rate”) as a result of changes to U.S. tax law. The adjustment conservatively increased the tax-effected Core OID balance and consequently reduced Adjusted TBVPS as any acceleration of the non-cash charge in future periods would flow through the financial statements at a 21% rate versus a previously modeled 35% rate.

(1) Excludes accelerated OID

Core original issue discount (Core OID) amortization expense is a non-GAAP financial measure for OID, primarily related to bond exchange OID which excludes international operations and future issuances.

Core outstanding original issue discount balance (Core OID balance) is a non-GAAP financial measure for outstanding OID, primarily related to bond exchange OID which excludes international operations and future issuances.
